"Guarantee Agreement?" The three of the Hagelos Demon King were stunned for a moment, not understanding what the so-called guarantee agreement meant.

I explained to them directly: "It can be seen from your words that you all hope to return to the Temple of Darkness, so I think I can give you a guarantee. I will help you communicate with Ditans and then directly let you return to the Temple of Darkness. I promise that Ditans will not hold you accountable for the fact that you were actually not responsible outside the Temple of Darkness, and you will pay me a reward for my good office for you. What do you think of my decision?"

When I heard what I said, the three people over there looked at each other, obviously exchanging opinions, but they didn't speak, and I didn't know what they had communicated, but I didn't care at all. If I could make money, I would naturally make money, and if I couldn't make money, I wouldn't be able to make money without it.

After a few eye contact, the three of them began to murmur again, but the room was so quiet that I almost heard them all. Of course, I didn't care even if I heard it. Anyway, they were all things that had nothing to do with me.

In the end, the three of them seemed to have discussed the result, and the Chief Guard Roswell asked me: "Are you really sure that you have the ability to guarantee that Ditans will not hold us accountable? You should know that our previous actions are actually equivalent to defecting from the Dark Temple!"

"Since I have mentioned the guarantee, I will definitely guarantee it. If something goes wrong, I will take responsibility. Don't worry, if Ditans refuses, I will stop his revenge, and as long as I disagree, he will never dare to touch you."

"You have the ability to save us under the noses of the Dark Temple?" This time, the attendant Clydea suspected my words.

I nodded with certainty and said, "You may not know much about the outside world because you rarely leave here recently. If you go outside and inquire, you will know that I definitely have the ability to prevent the Dark Temple from coming to touch you."

"If this is the case, I think this agreement can be signed." The attendant of Clydia expressed his final opinion.

The Great Demon King of Hagelos looked at the Roswell Guard next to him. The Great Demon King of Hagelos looked at the Captain Roswell Guard next to him. After confirming that his two right-hand arms agreed, the Great Demon King of Hagelos finally nodded and said, "In principle, we agree to sign such an agreement with you, but we want to know, what kind of reward do you need us to pay?"

"How is all the knowledge accumulated in the witchcraft system?" I said directly: "Just copy one and give it to me. Strictly speaking, you actually lost nothing, and I got enough benefits. Isn't such a deal very cost-effective?"

Of course, such a transaction cannot be simply described as cost-effective. Otherwise, modern society would not have had a technology blockade. Of course, although the three of Haglos Demon Kings have not come out to move around in recent hundreds of years, they are not stupid. They also know that if the technology is sold, they may be reversely eroded by their own technology. But they also know one thing, that is, they have no comparison with my organization, so there is no competitive relationship between us. If that is the case, then it will not change much whether the technology is transferred to me.

After pondering for a while, the Great Demon King Haglos decisively nodded and used technology to pay for the rewards. I quickly took out a temporary guarantee agreement and signed it. This thing is protected by the system. Naturally, they can rest assured.

"Ok, happy cooperation." We kept the guarantee agreement. We shook hands with each other, and then we opened a bottle of magic drink to celebrate. Of course, I took out the drink. The Great Demon King of Haglos squatted in such a place. Of course, it was impossible to entertain guests with advanced magic fruits like the rich and powerful Dark Temple.

Since such an agreement has been completed, the atmosphere between us has immediately become warm. After all, we will be a temporary cooperative relationship. As a guest, the Great Demon of Hagelos invited me to rest in the castle tonight and to attend the opening ceremony of the Magic Festival with them tomorrow morning, and of course I agreed. However, before that, I would ask the Chief Roswell to take me out, and first, to explain to the old witch and Glenn wizard, and the other was to visit the night market.

Although the Magic Festival has officially started tomorrow, it is actually the most lively time period tonight and tomorrow night. The wizards do not like the existence of light, they prefer activities at night, so it will be more lively than during the day. Because I have to concentrate on attracting the Magic Dessert Master tomorrow, I have no time to go out. Therefore, I am like taking advantage of the Magic Dessert Master tonight before the Magic Dessert Master comes, and first check out what is the magic festival here.

Remote rural areas also have the benefits of remote rural areas. Because the environment is blocked, there will definitely be no high-end goods outside. However, because the environment is blocked, there are often special supplies that cannot be bought in other places. For example, a group of American players had died in the Pacific Ocean and accidentally discovered an island. As a result, they actually found an NPC village on the island. Finally, they bought a very rare fishing line from them. The thickness is not as good as the hair of ordinary people, but the tensile resistance is comparable to that of cables with arms thickness. If the output is not too low, this kind of thing will definitely have great consumption prospects. The environment at this Magic Festival is the same. With such a closed environment, there may be some unknown good things, which are just convenient and simple.

With Chief Roswell's side, I was not worried that anyone would dare to cheat me. Even when I saw Chief Roswell following me respectfully, many merchants did not dare to say the price when I asked for the price, and just said that I just like to take it away. This shows how prestige of the Great Demon King and his group of people in this place is so deeply rooted in the hearts of the people. It is not only respect, but also a certain degree of fear. But thinking about the strength of the wizards here, let's look at Chief Roswell's weakest among the three people behind me. I immediately understood why the people here are so afraid of them. I am really not afraid, but they are several orders of magnitude inferior in strength!

"What is this?" Because the Magic Festival has not started yet, the shops have not opened much tonight. Those who come out to sell things are mobile vendors, and most of them are concentrated in the square in front of the castle. I only visited less than fifty meters and saw something that interests me.

The boss was worried when he heard my question, but after thinking about it, he still plucked up his courage and said to me: "This is a demon fly egg."

"Demon Fly?" I picked up the crystal-clear red object in confusion. This thing is probably the size of a cantaloupe, and it is basically red on the outside, but there are several purple meridians that look like blood vessels. It looks quite scary. The reason why I am interested in this thing is mainly because I found that the magic fluctuations on this thing are very special, and it feels like a magic black hole. Although it is also emitting magic fluctuations, for some reason, all the magic fluctuations spreading around were absorbed by this egg, and then the magic fly egg will emit a unique weak and thin fluctuations.

Seeing that I was interested in this thing, Chief Guard Roswell explained to me: "There are a lot of this thing in our place, and it is almost everywhere in the forest. However, the birth location of the demon fly eggs itself is not very fixed. So it is difficult to find it by purpose. I can only collect it by chance."

"What do you want this thing for?"

Commander Roswell looked at the stall owner, meaning that he would answer. After all, Commander Roswell is not a professional wizard. He knew that this thing was useful to wizards, so he didn't know what it was for.

The stall owner there immediately explained to me when he saw the look of the guard Roswell, "This is mainly used as a stabilizer for magic potion."

"Stabilizer?"

"Yes." said the stall owner: "If you know a little bit of magic pharmacy, you should know that after the magic power is highly enriched, it will become quite unstable, and the greater the density, the more unstable it is. However, if you add some juice squeezed from the magic fly eggs in moderation, you can quickly stabilize the energy substance."

"So amazing?"

"I don't know whether it's magical or not. We all use it this way, and it works very well."

"How much juice can this egg make?"

"Look at it. It usually looks like seventy to eighty flowers."

"Do?"

Chief Roswell quickly explained: "This is a unit of measurement here. It is used to represent the volume of the liquid. I am not very clear about the specific conversion, and you also know that I am not a legal profession."

The stall owner there heard our explanation. He quickly took out a small cup from the stall next to him and handed it to me: "This cup is the measurement cup for testing. Look, there is a scale inside the cup, and the top bar is ten."

I looked at it and found that the cup was not very big, just like an ordinary coffee cup. If you say that, the amount of seventy or eighty cups is seven or eight cups, and the actual amount is also quite large.

"If it is a high-energy solution, how much juice can be added to ensure stability? Also, will this thing be added to reduce the explosive power when it explodes?"

Thanks to the fact that the stalls here are all genuine wizards and not pure businessmen, even if my question is very professional, the stall owner still answered: "There is no conclusion about the stable ratio.... The quantity measured between my friends and I are not very accurate, but the rules are fixed. The higher the energy density of the energy solution, the more stabilizer needs to be added, and the stability of the energy substance itself will also affect the stability effect. In addition, the energy substance and the stabilizer themselves sometimes have some joint reactions. We have not yet discovered the reason for this reaction, but this reaction does interfere with the stability of the stabilizer, sometimes increasing stability, and sometimes reducing stability."

Whether the stability of the stabilizer is increased or decreased, as long as it is unpredictable, it is not a good thing. After all, high-energy substances are definitely not for the sake of being good-looking. No matter what high-energy substances are, everyone ultimately aims to utilize the energy in it. If the effect of the stabilizer decreases, it may lead to an unexpected explosion of the high-energy substance. The consequences can be imagined. If the effect of the stabilizer increases, it may not be a good thing. If the energy substance is too stable at a critical moment and needs to release energy, it will not respond. What should you do at this time? So, as long as it is an unpredictable result, it is not a good thing whether it is an increase or decrease.

"Stand owner, you haven't said whether this thing will affect the power of energy release?"

The stall owner shook his head and said, "The demon fly egg itself is also a high-energy substance, so it will not only not lower it, but may increase the explosive power."

I nodded and said, "It sounds like antifreeze!"

"Ah? What antifreeze?" I'm talking about gasoline antifreeze. Although there is oil in the game, the gasoline and diesel industries have not developed. So it's normal for the other party to not know about it. For example, in reality, the gasoline antifreeze used by cars in winter is actually a high-energy substance. Although its main function is to prevent gasoline from freezing, it is itself a high-combustion substance. If you don't add gasoline and use this thing to burn it completely, it will not only drive the car, but will cause the engine cylinder to burst due to excessive combustion.

This demon fly egg obviously has similar characteristics to antifreeze. It not only does not affect the explosion of high-energy substances, but also produces more terrifying explosive power. Of course, it is relatively stable and does not explode easily.

"How do you sell this thing?" After confirming that this thing will not cause an explosion, I wanted to get some back and hand it over to the research department for experimentation. After all, the liquefied magic crystal steam technology that our guild now uses is a high-energy substance polymer, and this thing is notoriously unstable. Although we have invested a lot of money and personnel to study anti-explosion methods, it can only be said that the effect has been very little. The only thing we can do is to take it lightly and will never explode. However, if there are a little more severe collisions and bumps, it can only be determined by the character.

Seeing that I was interested in buying, the stall owner unconsciously glanced at the Commander Roswell again. When I noticed his eyes, I immediately said first: "No need to reduce the price. Commander Roswell just came out for a walk with me. I didn't want me to rob your stuff, so just keep the quote. Just don't cheat me."

Although I said this, of course, the other party could not still sell it at the original price. It only quoted a relatively low price, but still in a reasonable range. Because this thing is everywhere in this forest, the price is not very high. Unfortunately, it is not easy to find it specifically, so the stall owner only has a few. After paying to buy all the demon fly eggs of the stall owner, we started to walk around again. Of course, as long as we find the demon fly eggs along the way, I will buy them. The large-scale experiment requires a lot of quantity, and if this can be used to stabilize the liquefied magic crystal steam, the demand will increase by several orders of magnitude. Of course, I don’t expect to rely on the natural production here.

The biggest reason why humans can have their current living conditions is that we can raise creatures. Since there are demon fly eggs here, hatching demon fly is also very simple. At worst, we can set up a demon fly breeding farm in the future, and then we can receive a large amount of demon fly eggs. Anyway, flies in reality are a species that cannot be killed even if they want them to die. The vitality of demon fly will only be stronger and will definitely be easy to feed.

In fact, there are quite a lot of demon fly eggs here, mainly scattered and messy. Almost every stall owner has more or less a few, and these demon fly eggs are not all the same size. Some are of good quality and large size, while others are cracked and very small.

Of course, Chief Roswell didn't know why I had such a special liking for the Demon Fly Egg, but his mission was to follow me to protect him. Of course, he himself felt that there was no need. After all, he knew the strength of the wizards here, but I could surpass the existence of the Great Demon King, so if there was a conflict, the one that needed protection was definitely not me.

Accompanied by Chief Roswell, we quickly visited the market. In addition to purchasing a large number of demon fly eggs, most of the things we saw were rags, and of course there were some things worth noting. In fact, in addition to the demon fly eggs, I also bought three things.

The first is the leaves of a plant. It is said that the growth conditions of this plant are extremely special, cannot be transplanted and cultivated, and cannot be artificially raised, and the growth environment is messy and cannot be found in any pattern. However, although the growth method of this plant is very strange, their leaves are really good things, because the liquid obtained after the leaves of this plant can actually raise swords. Of course, raising swords is a saying. If you use it to raise knives and guns, no one will say you, and the effect is the same. As long as the weapon is soaked in the leaf juice of this plant, the durability of the weapon will slowly increase. Note that what is rising is not durability but the upper limit of durability.

It is precisely because this thing can increase the durability limit of a weapon. Therefore, the more advanced the weapon is, the more it needs it. The advanced weapon must be in the hands of advanced players. And because advanced players must be very rich and powerful, the purchase price of this thing is getting higher and higher. Unfortunately, this thing is distributed randomly around the world and there is no pattern at all, so everyone you meet looks like you have won a lottery and cannot deliberately harvest it. Because of this reason, the price of this thing has always remained high. And there is no market price.

However, today I found a treasure. I didn't expect that there was a place in the nearby valley where two of these plants grew, and they were next to each other. Most of them were wizards, and there were very few people who needed weapons. So the wizard who discovered it only picked a small number of leaves, so the plant was able to continue growing. Every time the wizard came to participate in the Magic Festival, he would pick a few pieces. Over the years, a lot of them have been accumulated, and most of them have not been sold. In addition, this leaf has a characteristic.

Even if it is picked, it will not deteriorate. So it is not a problem to preserve it at all. This made the wizard accumulate a lot of these leaves. Originally, he just brought a few pieces to try his luck this time, but who knew that he had actually encountered a buyer like me. Not only did he buy everything in his hands, but he also bought all the inventory in his house. Of course, I haven't gotten those inventory yet, because the guy is still on the way back to get it. However, according to him, the distance is very close and he will definitely come back tomorrow morning.

The second item is relatively simple. It is a seed without a seed. However, this seed is not simple, because this thing is actually the seed of the Giant God Wood.

The Giant God Tree is a close relative of the World Tree. It is said that it has a certain relationship with the natural tree of the elves, but this Giant God Tree does not have so many strange abilities. The only feature is that it can grow very large and its hard texture can be used as a very good wood. Aisinger does not need to plant trees. Besides, the zombies climb and skeletons run all over the streets cannot grow any big trees. However, although Aisinger cannot use it, Tianyu City is very suitable. Tianyu City itself is at the junction of Germany, France and Switzerland, and is protected and divided by the border mountains, and there is no cover on the top of his head. If such a giant God Tree can be found in the center of Tianyu City and find some creature-gathering items to grow into a towering tree in a short time, Tianyu City will be safer at that time.

The third item I bought at Magic Festival this time is a recipe that can create a deformation potion. This thing is basically a magic-level thing in the eyes of wizards, and it doesn't take it seriously at all, but I don't know that this thing is of great use.

The main problem of this kind of error is the technical system. It seems that the refining of potions is more effective in witchcraft, but the alchemy in the magic system is quite complex and has few results. For wizards, the deformation potion is completely apprentice-level potion, but for alchemists, the transformation potion is almost the same even if it is not a magical medicine. This is the gap caused by different systems. Just like for biological civilizations that specialize in genetic engineering, extending the lifespan of decades is an operation problem for middle school students. However, for mechanical civilizations, the technology to extend human lifespan is basically equal to high-end disciplines. It is not a question of who is stronger and who is weak, it is a question of technical expertise.

Deformation potion can make people become a designated creature within a certain period of time. During this period, this person actually becomes this creature completely, so no detection technique can detect it. To use an inappropriate metaphor, if you make a person use the Deformation potion to turn into a sheep and then slaughter him into roasted lamb, it will definitely taste no different from a real sheep, because during the period of the drug effect, he is indeed a sheep. This is the magic of Deformation potion.

Because of the special ability of this deformation potion, for spies, this thing is simply a magical medicine, and its usefulness is too great. Even ordinary players can save their lives at critical moments, at least you can consider running away with a sparrow or simply turning into a mouse to dig into a hole in the ground to hide.

This deformation potion is so useful that it is difficult for those magical alchemists outside to make, so the price is high and it is absolutely hard to find a medicine. However, here, I only used fifty magic coins to buy this recipe, and I forced it to the other party. The stall owner was only willing to collect ten magic coins, because except for the newly-entered apprentice, the wizards here can match all this kind of thing, but no one thought of writing it out to sell the medicine.

Of course, the other party doesn't care about it, but I know the price of this thing, so I forced fifty magic coins to the other party. But it's still scary to think about it, because according to the market conditions here, fifty magic coins are the price of five white skeletons. If you can get five white skeletons outside, you can sell one gold coin, even if you have strong sales ability, if you convert it, I will get this formula in less than one gold coin. However, in the outside world, the world price of the transforming potion is - one hundred crystal coins per bottle.

Although the things I bought before were also good, I only realized after I had this recipe that this thing is the most valuable. Moreover, because of this recipe, I decided to take a few wizards to our guild when I went back. Although I had obtained all the technical information of the witchcraft system from the Great Demon King, there were no real wizards, and there would still be many detours with the information, so I planned to take a few wizards back to help us enrich the technical system of our guild.

The value of science and technology is like the connection line between points. If you have two points, then you only have one line, three points can connect three lines, and four points are six lines. After that, as more and more points, the increase of lines will be more terrifying than the increase of points. Therefore, the more technology, the greater the value, and a new technology will often make many useless technologies suddenly useful, and can also make some very low-value technologies valuable. This is also the reason why I have been working hard to enrich the technical system of our guild. Compatibility and package are the best way to develop. If one goes to black, it is not development, it is self-destruction.

After visiting the night market, I had nothing to do, so I returned to the castle with Captain Roswell. Although I didn’t have to sleep, it was hard to speculate since I invited me. Anyway, I was alone in the guest room, and no one would look at me, so I arranged whether to sleep or not. I just used this time to study the various information about the magic dessert master collected in the night market. I really hoped to kidnap this magic dessert master, so I conducted a full investigation in advance. With the opportunity of purchasing magic fly eggs, I almost asked all the wizards in the market and got information about some things that the magic dessert master had purchased from them. After knowing what the other party had bought, you can know the other party’s general preferences and needs. This information is very helpful for me to abduct this magic dessert master tomorrow, and now I can study these materials for screening.

In fact, it is a very troublesome thing to organize the information about the Magic Dessert Master all night. I and my group of demons were all sorted out all the relevant information of the Magic Dessert Master. Finally, I came to a lot of conclusions. One of the most important ones is that the Magic Dessert Master seems to be a woman, and I don’t like men to get close to her. To put it simply, this person has a natural phobia for all male creatures, and will become emotionally unstable as soon as he gets close. Therefore, when you meet the Magic Dessert Master later, you must not use the Ziri account, otherwise the recruitment plan will be completely out of the blue. I was even considering whether to ask Ling to take a group of female demons to recruit the other party, and I might as well not show up. (To be continued)!~!
