"This bottle of potion has a good effect, its physical fitness has improved a lot, and its vision has evolved to a point beyond ordinary people. The side effects are very small, and it only weakened for about half a day after taking it." Sylvia put the empty bottles left by the bottles of potion that had been tested on the table, and then carefully introduced: "This bottle of potion has the best effect, the physical fitness has the greatest improvement, which is comparable to the sacred warriors who have passed a divine congratulation ceremony, but the side effects are also very large. Some mutated tissues appeared on the user, but fortunately it was hidden. The other bottles of potion have very average effects. Although the physical fitness has improved a little after use, the improvement is not particularly large. Moreover, it requires a lot of food after use. There is a risk of losing mind during the eating process, and there is even signs of attacking people. After eating a lot, the reason will recover, but the personality will also change."

"These potions mainly use the blood of the same mutant monster." Leo looked at the bottle on the table, with a hint of confusion on his face, and said, "It's just that the auxiliary materials that match the blood are different, but their efficacy is so different, it's like a different potion. It seems that the power that caused the wild beast to undergo uncontrollable mutation was also left in the monster's blood, and affected the effect of the potion."

"What should I do?" Hearing Leo's words, Sylvia couldn't help but frown again.

"Two solutions, one is to continue to use this kind of medicine, but before selling it, the effects of these medicines are divided and several qualities are developed. Those who pay more will naturally have good results. Those who pay less will have less side effects. Those who pay less will have only those who have greater side effects and low effects." Leo seemed to have expected this for a long time, so he quickly gave two answers, saying: "The other solution is not to use monster blood as the main medicine for the medicine, and use other materials. In that case, it will increase a lot of additional costs and it is also very troublesome to make. It is impossible for not a very skilled alchemist or pharmacist to make a bottle of qualified medicine."

"Is it easy to make this kind of potion made from monster blood essence now?" Sylvia asked in confusion.

"It's very simple. When I was developing, I had already considered mass production and production issues. I especially simplified the production method. Even an ordinary person could make it." Leo said and ordered Sylvia to a small room next to him.

I saw some equipment that Leo had made recently. Leo came directly to a piece of equipment that looked like a food box, opened the upper lid, then took out a metal test tube from it, and took out a bottle of monster blood to be used for testing from the side, poured the test tube full, and then inserted the test tube into its original position and closed the lid of the food box.

Afterwards, he saw him start a small steam engine next to the food box. The gears of the steam engine immediately drove the food box to rotate rapidly. It was not until a few minutes later that he stopped the steam engine. After the food box stopped rotating, he took out the test tube and handed it to Sylvia, signaling her to take a look.

Sylvia opened the seal plug of the test tube and looked inside, and found that the blood that should have been very viscous had now turned into a clear liquid, and the viscous blood had sink to the bottom and became even more viscous.

"Is the blood extracted and refined so simply?" Seeing this scene, even though Sylvia didn't know much about alchemy, she knew very well what was going on, and asked immediately in surprise.

In Sylvia's memory, the scholars of the life school of medical schools and the blood wizard Lawrence recruited by the Dodd Group often need to extract some monster blood or liquid materials. The methods they used were very complicated and complicated, and took a long time. At the shortest, they took half a little time to achieve the effect of refining. Even if there was a little mistake during the refining process, all previous efforts would be wasted.

Now Leo has completed the refining of blood in such a short time, and the refining process is so simple. As Leo said, even an ordinary person can operate it. More importantly, Leo's blood extracted by Leo is clearer than the blood extracted by the blood wizard Lawrence through the secret technique. Although she doesn't know what impact this has on use, according to common sense, the clearer the clearer the less impurities, the stronger the effect will naturally be.

"This is a centrifuge that can be used to refine liquid materials." Leo briefly introduced the centrifuge he modified and pointed out in detail the functions of each component.

If it were in the past, Leo wanted to make a centrifuge with the same effect, he would probably need a steam furnace as big as a room, gears and other components as individually, and the effect would not be as good as the one now.

However, as the world began to mutate, various mechanical parts can improve their efficacy exponentially or even dozens of times while the power consumption remains unchanged, allowing Leo to miniaturize and modularly.

While listening to Leo's introduction to the centrifuge, other uses of the centrifuge appeared in Sylvia's mind. She felt that with this thing, perhaps the medical department she had planned for a long time could be successfully established. Those in the Life School did not have to stay in the laboratory of Bran Forest and wasting the knowledge in their minds in vain.

"With this centrifuge, how much does it cost to make a physical agent that uses monster blood as the main raw material?" Sylvia asked with great concern after listening to the introduction to the centrifuge.

Leo reported a number.

"Why don't you use this kind of potion for the blood of monsters?" Sylvia asked again.

Leo reported another estimated number.

Hearing this number, Sylvia couldn't help but remain silent for a moment. This number was nothing to her, but in the eyes of ordinary people, it was definitely an addition. The cost of the two drugs was hundreds of times more.

However, thinking about it, there are so many mutant monsters outside the city. Every time the monsters die in the tide of monsters outside the Odorene's wall, the corpses of monsters are piled up like mountains, and it takes several days for the whole city to completely remove them. Therefore, the blood and organs of these monsters are cheaper than those of wild beasts. Only a few monsters with extraordinary power have special value.

However, it is difficult to find on the market with herbs or ores with special effects. You need to go deep into the forests and mountains of monsters to find them. In the past, when there was no threat of monsters, it was already difficult to find these materials. Now a large number of mutant monsters are entrenched in such places. Any entry into forests and mountains is a life-and-death test, and the price is naturally high.

Needless to think too much, Sylvia chose to continue using monster blood as the main material for the potion, because she knew very well that although it was safer to use other materials, the price was too high, and the potion used with that material would inevitably not be used by ordinary people, which would violate the plan they had set earlier.

Although there will be uncertainty in the efficacy of the agent made with the blood of mutant monsters, if the drug is refined, the efficacy and side effects are good and bad, and the agent is divided into several grades. The agent with too poor effect or too much side effects will be discarded. Even if it will cause some cost increase, compared to the kind of agent that requires special personnel to refine and the material cost is high, she can still make a lot of money and can also mass-produce it.

Afterwards, Sylvia discussed things with Leo, and sent someone to learn how to make this monster blood potion from Leo, and also learned how to make and assemble parts of centrifuges, etc.

After discussing various things, Sylvia was about to leave and come back in two days. However, when she was about to leave the mine, she suddenly thought of something and turned back and said to Leo: "I also forgot one thing. The long night period will be coming in a few days. According to the news released by the Shaman Church, this long night period will be about twenty days, and there will definitely be a monster tide. Don't you want to see how Odorene resists the monster tide? Then I will have someone arrange you on the wall."

The long night period is a unique phenomenon in the Mosang continent. It only appears in the depths of the wasteland at first. Almost every year, some areas in the depths of the wasteland will fall into the darkness, for several days or even more than ten days. What’s strange is that the long night period will only occur in specific places. Once you leave that place, it will instantly turn into daytime. Therefore, during the long night period, it will take one step toward the darkness, and take one step back is a wonder of daytime.

However, for those whose lives are affected by long nights, such a wonder is a big problem that they have to worry about every year, because in the boundaries that are covered by long nights, all creatures will be more or less invaded by a mysterious force. This force will not allow people to gain any mysterious force, but it will affect others' moods and make the affected people particularly warlike and violent.

Although the long night period is so dangerous, before the world changes, the long night period occurs in the depths of the wasteland. Moreover, the shamanism can often predict the locations covered by the long night period and Fan Wei, and notify the tribes there in advance to leave, so long night period is not a particularly big trouble in the wasteland.

But as the world mutates, the coverage of the long night period is also expanding rapidly, and the edge of the range is also expanding towards the outside, gradually leaving the wasteland and entering the civilized country of the Mosang continent.

Five years ago, Odorene was included in it, and the residents of Odorene saw how bad the adverse effects brought by the Odorene period were. Not to mention the monsters outside the city who were controlled by violent thoughts. The residents who received the influence of the long night period, their personality changed and became extremely violent, and they hit the unprepared Odorene with a heavy blow. At the same time as the monster tide, Odorene also riots from the lower classes inside, and the riots were so great that they affected the fortifications on the city walls that Odorene was almost broken.

Later, Odorene paid special attention to the long night time every year, and made various preparations. In addition to adding a large number of patrol guards and city defense troops, the municipal government will also distribute a potion to everyone in the city to resist the mysterious infectious force that appears with the long night time. This potion will not be affected by external forces for a period of time and become extremely violent.

However, these are just some information that can be disclosed, about hidden dangers during the long night period, and some information that cannot be made public to the public. These information all mention that after the long night period, some unpredictable strange things will happen. What specific things are there, and Leo didn't say much about the information that he saw.

After recalling the relevant information a little, Leo asked in confusion: "I remember that the long night period should not happen for a few months? Why does it suddenly appear now?"

"I don't know this either, but the Shamanism has issued an announcement, which should not be fake." Sylvia said seriously.

Shamanism has been dealing with long nights all year round and has compiled a very complete set of secret techniques that can accurately know the occurrence time of long nights, and the error is less than one day. So once the Shaman Church issues an announcement, it means that long nights are really coming.

The reason for the occurrence of long night period has always been a mystery. Even the shamanism, who has been studying long night periods, is confused and ignorant of this strange phenomenon. However, Leo feels that the so-called long night period should be related to the movement of celestial bodies. It should be a certain period of each year. A satellite in the sky just blocks the sun and a certain area of ​​the Mosan continent in the Viron World, which causes the appearance and disappearance of long night periods, some like a solar eclipse.

As for why the coverage of long-night periods is expanded, this is very simple to explain, that is, the huge obstruction satellite is approaching the world of Viron, and its shape is getting bigger, so the covering area naturally increases.

But such statements obviously cannot explain other things, such as the creatures within the long night period becoming violent and aggressive, and various strange things will appear in that area, even the True God Church and Shamanism cannot figure out the strange things, etc.

"Don't worry." Seeing Leo frowning, Sylvia thought he was worried about his safety in the long night period, so she said: "This is not the first time I have encountered the long night period. The power of the long night period will not have any impact on me. And as long as I am not alone, there are many people around me, and you will not encounter any strange things. You don't have to worry about this, but you may stay here alone at that time..."

Leo gestured to Sylvia, smiled and shook his head, and said, "It's okay, I just happened to see what the secret of this famous long night period is."

Sylvia looked at Leo who was eager to try his clothes, and couldn't help but raise her eyebrows and warned: "Just look, don't be missing for twenty years. If that's true, I won't wait for you for twenty years."
