The last time I came here with Rose, I didn’t bring it, but this time I was prepared. I released the crystal beetle and started gnawing on steel. These little guys have a special liking for hard things. Gnawing on steel is like eating cakes. According to the key points explained by Woma, we first need to determine the reserves of steel. The specific way is to first calculate the steel reserves in the tree part and then calculate the reserves of steel under the ground.

The reserves of trees are easier to deal with. The average height of trees in the forest is about 270 meters, and the average diameter of the bottom of the tree is 19 meters. However, the trunk is thinner and thinner as the tree trunk is upward, and there are tree forks and other things that cannot be measured uniformly. So we roughly calculate a tree into a perfect cylinder with a diameter of 14 meters and a height of 270 meters. In this way, the volume of a tree is about 41,563 cubic meters. The specific gravity of iron is 7.86, but this is steel, because some special materials are mixed with specific gravity of about 7.81. That is to say, the weight of this tree is about 324,607 tons. After measurement, the entire cave is an oblong shape with a total area of ​​about 14,400 square kilometers. Among them, the Sand Forest only occupies about 10,000 square kilometers. These giant steel trees are very large, one

The tree covers an area of ​​about 900 square meters, which means that if the gap between trees is removed, one square kilometer can only accommodate about 1,000 trees, and there are about 10 million trees in the entire forest. This can calculate that the steel reserves of these big steel trees are about 3246.07 billion tons. A warship has an empty load displacement of 100,000 tons, is it a great deal? The aircraft carrier has an empty load of less than 100,000 tons! If all of these steels are used to build warships, at least 32.46 million warships can be built. So many ships are used to build warships, and one person will cost tens of millions of people. We cannot use so many warships at all, and of course we will not build so many warships. According to our guild's ability, there are many warships with one to two thousand warships. Even if all of them are built with a weight of 100,000 tons, only 2000 tons of steel will be only 2000 tons.

After I finished counting, a German mm next to me said in surprise: "Will that tree build 3 ships still be left? We can't use the entire forest at all. Even if we need to build 2,000 warships, only 600 trees are enough."

At this time, Woma also said: "It seems that we can't use the steel we have turned into when digging the ground. Just get these trees back."

"I think since the steel reserves are so large, why don't we try the synthetics of golden beetles? Let them eat the steel and maybe they can get high-hardness materials."

"This method is good, try it quickly!" Woma was excited when he heard it.

I quickly asked the crystal beetle to do an experiment. I directed the golden beetle to climb up to the top of the tree and started gnawing on the tree.

Xiaoyao Daodao asked, "Why don't you put it down and eat it? So we can see it!"

"A tree has more than 300,000 tons, will you help me if it falls?"

"oh!"

The speed of 1.2 million crystal beetles gnaw on things is really terrifying. A tree was gnawed in less than an hour. After they were finished eating, I directed them to spit out the synthetic product, and the result was a black substance. When the thing gathered large enough, I picked up one and looked at it. It actually showed that it was a material and also its attributes. I read out the attributes. "Ink steel, the product after the magic of steel has a black and matte surface, and can be melted. The melting point is slightly higher than that of steel, and its hardness is more than twice that of steel, and its specific gravity is 7.9 and slightly higher than that of steel."

"Good thing!" Woma sighed: "The hardness is more than twice that of steel, which means that the ink steel plate is stronger when the thickness is only half of the steel plate. To achieve the hardness of the ink steel plate, the steel plate must be more than twice the thickness of the ink steel plate."

Another German mm said: "Don't the president's crystal beetle suffers losses every time? Let's see how many it has come out?"

After hearing what she said, I quickly asked the crystal beetle to concentrate the ink steel spit out, which scared me. More than 3200 tons of steel were eaten and more than 3,200 tons of ink steel were produced, and the output was only one percent. Fortunately, there were more steel here, and one percent could bear it. Aisinger's dock had only 4 slots, which means that at most 4 docks could be built. According to the size of the slots of Aisinger, a dock should have 4 shipbuilding spaces. This is a game, shipbuilding is very fast, but each shipbuilding space can only build one ship a day. 16 warships cost up to 1.6 million tons of steel, and the crystal beetle only produces 3,200 tons of ink steel in one hour. It seems that the output is a bit unsatisfactory! Why are there not enough crystal beetles!

Seeing my face, Woma asked, "What? Is the situation not good?"

I nodded. "The production loss is only one percent. The 1.2 million crystal beetles can only produce nearly 80,000 tons of ink steel a day when they drive at full capacity, which is not enough for a warship with a large tonnage."

Woma comforted me and said, "You don't have to be so sad. The warship is not entirely made of steel. There are still many parts inside the hull with other materials. The warship shell that consumes 80,000 tons of ink steel, and the weight of the internal parts should be more than 100,000 tons. The captain may have to exceed 1,000 meters. Such a warship is already a super-super warship. The American Iahua-class battleship is only 45,000 tons and has a length of more than 290 meters. It is already the top three battleships in the world. We don't have to build such a large warship? The aircraft carrier has a full load displacement of less than 100,000 tons! Why are we doing that big?"

"I don't want to build warships according to standard specifications. We have the advantages of thrusters, with high thrust, so we don't have to consider speed. Moreover, our naval guns are too large, and if the warship is not large, we cannot guarantee accurate shooting."

"You don't want to build a sea bunker, do you?"

I smiled and said, "Is it very smart? I just want to build a sea bunker. I don't have to consider the load. I ask our warship's armor thickness to double. Because of the hardness of ink steel, the actual hardness of our warship is 5 times that of ordinary warships, and the thickness of the armor is only 2 times. How big is it to build such a warship of 80,000 tons of ink steel?"

Woma calculated slightly. "The armor doubled, and the special defenses of important parts are still 100,000 tons. In this way, the full load displacement is about 150,000 tons, and the length of the hull should not exceed 700 meters. Oh my God! Can such a warship run fast?"

"When we go back, we will build a test ship first. Anyway, the custom-made thrusters in Atlantis have arrived."

"I'd better talk about these things when I go back, I'm a little dizzy."

"Haha! Well, let's talk about it when you go back."

After a night of busyness, we finally built several large teleportation arrays. Because it will change in the future, this time we built a temporary teleportation array. After dawn, a large number of craftsmen and NPCs and players crowded here to start work. Because there is no need for city walls and defense facilities, there is no most expensive and troublesome thing in urban construction. The construction speed of Steel City is surprisingly fast. After dawn, Steel City is very busy, and I took Woma back to Aisinger.

At around 8 o'clock in the morning, a large group of players appeared outside the city of Aisinger. The players of our guild all had standard equipment. The people outside the city were wearing messy clothes that were not from our guild. Our guild rarely contacted the outside world. Logically speaking, there shouldn't be a large group of people entering the vicinity of Aisinger. Vader carefully ordered the guard and asked someone to notify me.

When I arrived on the city wall, the team outside had reached less than 3 kilometers outside the city. In this way, the number of people was less than 3,000, and it looked like a guard. There were a large number of carriages among these players. Judging from the ruts, the carriages were not light. Now it seems that these are not here to attack us. There are not many players from our guilds. Not to mention that there are NPC guards in the city, even if we fight to the ground, our players can deal with them. No one is so stupid that they use 3,000 people to attack a city like Aisinger. Besides, I have never heard of anyone bringing so many carriages in war!

I asked Vader to pay attention, but there was no need to be too nervous. I went to the inside of the city wall, standing at the window halfway up the wall, looking at the city gate passage. Although there was already artificial intelligence, NPC could not be fully human after all. In order to prevent it, I arranged for players to stand guard at the door, and the shifts were rotated in half an hour. Fortunately, Aisinger only had one external gate.

At this time, the four players were standing at the city gate in their entire set of equipment, but none of them had helmets, which was for the sake of convenience. Of course, the guards could not only use players, the players were responsible for commanding, and if they really encountered the enemy, they were still powerful. At this time, there were two rows of NPCs standing neatly on both sides of the door, each of which consisted of 8 seraphic angels, 2 sub-god knights, 20 blood lords, 50 dark night guards, and 200 blood skeletons. As long as there was something wrong, these people would block the enemy and the players would call people using the guild channel. In addition, the residence of Red Flame is also very close to the city gate. If there is a battle, he will arrive immediately. If there is no ten thousand people, don't expect to rush in.

The player team slowly arrived outside the city, and five horse-riding players left the team and ran first. The four gate-guarding mms in our guild had already stood in the middle of the road, and the NPC behind them also realized that these people had problems and stood behind these 4 mms. Whenever there was something wrong, they could immediately rescue the 4 players.

Maybe he was scared by this formation, and the five players outside did not dare to run too close. The leading knight stopped, and the four people behind him also stopped. The knight shouted to this side: "Is this Aisinger?"

"Yes. What's wrong with you?" Now only one of the four mm guarding the goal is Chinese, so of course she is responsible for her speech. "Aisinger only allows our guild players to enter and exit NPC for the time being."

"Your guild defeated the Temple of Light some time ago, right?" the knight asked.

The four mms of our guild put their hands on the weapon at the same time. "What do you mean?" The npcs behind the mms have already pulled out all the weapons.

"Don't get me wrong, I'll just check it out." He pointed to the convoy behind him. "These are war reparations that the Temple of Light needs to pay to you, but they are punished themselves and cannot leave the city, so they hire us to transport the goods."

My private chat suddenly rang. "President, we are the city gate guards. A team of players just said it was an escort..."

I interrupted her. "I'm in the window above you."

She looked up at me when she heard me, and I waved to her and said in a private chat: "Let them come in first, I will call the NPC guards to come over to see you. Three thousand people can't make any trouble. By the way, check the vehicles. There are many terrorists these days, and it will be bad if they pull explosives."

The mm couldn't help laughing, and then closed the private chat. "Come in, but the vehicle needs to be inspected."

"No problem, this is your thing anyway." The knight was able to speak.

Player mm waved forward, and the blood skeletons behind ran out. The convoy passed one by one, and the blood skeletons checked the vehicles one by one. After a while, the entire convoy drove into the city.

"Where are your president?" asked the Cavaliers who led the team.

The gatekeeper's mm instinctively looked up at me. This silly girl was exposed in one sentence. I quickly flashed back and left the window. They shouldn't have seen it. They quickly teleported to the teleportation array near the city gate, and then walked out of it. He pretended not to know anything and shouted, "What's wrong? Vader called me over in a hurry?"

The Chinese mm opened her mouth and wanted to defend something. The German mm beside her responded quickly and held her down. "President! This knight sent the last part of the compensation supplies of the Temple of Light. We treated them as enemies at the beginning!"

"Oh! Is the supplies shipped? That's great." I turned to the NPC guard next to me and said, "Transfer things to the warehouse, don't forget to check the list."

"Yes!" The guard immediately began to leave with the convoy.

Captain Cavaliers took out a scroll and handed it to me. "Please sign for it. Please confirm that our transportation will be completed."

I asked while checking the contents of the scroll, "Are you players?"

"certainly!"

"In the past, weren't the NPC transport team responsible for transporting goods?"

The player said: "The Temple of Light has been banned by the system. Now all the Temple of Light NPCs cannot leave the city."

"Isn't the transport team free NPC?"

"But recently, a large number of thieves have appeared outside the city. It is extremely unsafe to leave the city. The temple must protect the transportation team, but they cannot come out themselves and have to hire players to come out. In fact, there were players escorting the team a long time ago, but at that time, Guangming NPC was not restricted from moving. We are generally responsible for small-scale transportation, and now we have to be responsible for even big deals!"

"Aren't they afraid that you will steal from your custody?"

"Do you think NPC is stupid? We paid a deposit equivalent to one-tenth of the value of the goods, and we were all recorded. If the items are lost, we must repay all the losses, otherwise we will be wanted by the system. Before the Temple of Light was confined, a small escort team had been guarding and stolen. At first, they thought it was just wanted by the Temple of Light, but they thought it would be enough to hide from the dark forces. After doing this, they went to the city controlled by the Temple of Light. The NPC over there actually said that these players are people with no credibility. The Temple of Darkness should not be people who are not trustworthy, but they were bombarded out. Later, those players were chased by other players hired by the Temple of Light.

The temple is different from the players. Players usually ask for several kills. The Temple of Light is unlimited. You kill him once and get money once. This means killing the player back to the novice village. Those unlucky people were finally scared to return the thing and then cancel the pursuit order. Since then, no one dared to stole it again. Anyone with a thief guard is fighting to the death. By the way, there is also a believer of the temple in the team, which is that." The knight secretly pointed it to me. "He is not a member of the Temple of Light, but he listened to the temple. Every guard has such a npc following. The temple relies on them to judge whether the guard is stole it."

"No wonder!" I heard the player in charge of the verification say that the items were complete, so I pressed the confirmation on the delivery certificate to hand it back to the knight. "Okay, thank you for your hard work. Aisinger is temporarily in a state of war, so he will not accept the visit. If you are willing, you can have a meal in our cafeteria before leaving, and if you don't want to leave, you can leave immediately. We have a teleportation array and don't have to walk back."

"Thank you, we have eaten dry food. Just borrow the teleportation array and use it."
Chapter completed!
