The second update is here.

Wang Kuang didn't expect that Wang Wu's speed was so fast that he asked Huang Da to send a message back to ask Wang Wu to try to make micro holes. In just a few days, he made one, and the effect seemed to be good. I don't know how he made it. Judging from the effect of Xiao Wang Sheng's trial just now, the diameter of the hole was a little thicker than the hair, and it was not even a millimeter away. It was far beyond Wang Kuang's expectations to be able to achieve this. Because this is not an internal combustion engine, the requirements for the atomization effect are not so high. Even if the small holes cannot be made, Wang Kuang can add one or two layers of nets deteriorated from thin metal wires in front of the nozzle. If the oil sprays on the net, it will naturally be dispersed into a fog.

The jade carving in Xiao Wang Sheng's hand should be the nozzle that Wang Wu imagined, which is already quite decent. The reason why there are water marks is that it is filled with water. Due to the capillary action, it will seep out, but it will not drip. Only when it touches the surface of the object, it can be brought out by relying on the tension of the water itself. The nozzle that Wang Kuang wants has a diameter of millimeters, and then a conical port can be used to make it possible. If you want the effect to be better, you can add another needle in front of the oil passage of the nozzle, aim it at the center of the nozzle, disturb the liquid, and optimize the atomization effect.

The hardness of jade and iron are not very different. Relatively speaking, jade is harder, and jade is easy to break, and iron will not have such concerns. Therefore, theoretically, since jade can make such fine holes, iron can be too. At this moment, Wang Kuang was full of confidence. The nozzle was the level he was most worried about, and he was not worried about other components. For artificial pump oil and oil passage sealing, it is not a problem that cannot be solved. If sealing, if there is no rubber as a sealing ring and using cork, the cork oil will expand, and there is not much pressure in the oil passage, and one kilogram will be overwhelmed. Therefore, these are all easy to solve.

At this time, the sky was almost dark. When he arrived at Wang Wu's courtyard, Wang Wu was busy with a few candles, squinting his eyes. When Wang Kuang saw it, he quickly stepped forward and moved the candles away, snatched the tool from Wang Wu's hand, and blamed him: "Fifth Brother, it's so dark, you don't care about your eyes. If you keep doing this, your eyes can't stand it. In a few years, what should I do? I also want Brother Wu to do more for me in the future, so I can't let you rest after working hard for a few years."

Wang Wu smiled and said, "It's not a big deal. If you try it successfully, you will be familiar with it in the future and you won't have to touch the dark anymore." At this moment, on the workbench in front of him, there were iron blocks thick with fingers. He was just busy with this.

Wang Kuang was angry and funny, but after all, it was his own negligence. He didn't expect that Wang Wu would start trying to drill holes after receiving the letter. So when he first explained Huang Da, he only said how thick the hole should be. He did not say how deep the hole should be, nor did he say when he wanted it.

In fact, the length of the nozzle that Wang Kuang needs to make is only two or three millimeters at most. If it is so long, it is enough to form atomization. If the nozzle mouth is longer than this, just create a cone in other places. Moreover, the nozzle must be connected to the nozzle. As for Wang Wu, since it is said that it is necessary to drill as long as it can, and it can drill one day earlier, then it will not delay Wang Kuang's affairs. He did not know that if Wang Kuang wanted to test the nozzle, he had to wait for the turbulent oil from the oil lake to come over, and then test distillation and choose the best fraction to start testing the effect of the nozzle.

Similarly, Old Man Xu and his team had to think about the artificial oil pump mechanism, and they had to wait until Xu Guoxu went to sea before starting the test. They also had to wait until Wang Kuang extracted the oil. The viscosity of oil and water was different. This kind of test could be replaced by water at the beginning, but if it really wanted to pass the test, it would be done. If it could not be done, it would have to be pushed down and started over again. Therefore, this nozzle should be made as long as it can make progress before next winter. Now, there will be one and a half years left to next winter.

Seeing that Wang Wu was still not satisfied, he was not good to wait until he turned around, and he could pick up the tool and try it. Wang Kuang had to sketch his request for the nozzle and told him that he could drill out fifty small holes in the iron plate as thick as half a chopstick and half a copper coin size. And there was plenty of time. With Wang Wu's current progress, it would be too late to do it after a year.

Seeing Wang Kuang's statement like this, Wang Wu smiled and collected the tools. As a jade maid, he knew the importance of his eyes. Since he had plenty of time and according to the pictures given by Wang Kuang, he was very sure of making them, so he naturally didn't have to rush to work.

It's night without saying anything.

The next morning, the craftsmen who Wang Ling invited came to the door early. These craftsmen were the leaders who helped Wang Kuang become the yard where Fulai was. Over the years, Fulai and Wang's work were basically for them to do, and they were very happy to take on the work related to the little boss. Needless to say, the usual foods were delivered by Fulai Inn, which was much better than the ones they cooked. Therefore, in recent years, they have worked hard. In their opinion, since the little family looked down on them, they had to be worthy of the little boss. If it weren't for the little boss' insistence, they wouldn't even ask for wages. So, Wang Ling sent someone to tell them the day before, and they rushed over early.

The Wang family did not have secret rooms, but the secret rooms built in the past were used to store property, and there were many good Tianhuang inside. Of course, Wang Kuang would not go there stupidly to inlay Cao Cao. If something happened, for example, suddenly there was a crack in space and swallowing his own property, wouldn’t it be a big loss? Therefore, it would be necessary to build another secret room, but the secret room is not as simple as Wang Kuang thought last night. He first built two secret rooms, one big one, one small one, and the big one, and then between the two secret rooms, in addition to the small stone window that can be pushed and pulled, there are two small holes connected with each other, and the hole is not big, and it is also

It is a little bigger than a tea cup, and it can hold a small bamboo gratin in. If you want Cao Cao to return to his position, just dig a hole in the small stone chamber so that the luminous stone can be embedded in it tightly. Then Cao Cao put it on the side and used a bamboo to pull it back. He was worried that there would be resistance, so a small wooden hammer would be hung on the other hole. Cao Cao could not return to his position automatically, so he used a small wooden hammer to go down. Of course, in addition to the two small holes and a small window, there is another hole that is left as an observation hole. Wang Kuang is preparing to embed a thick piece of glass. If he can't burn such a thick glass, it wouldn't be tight. He cut it directly with crystals. In the treasure room, there are several crystals as big as melons.

This is already the best protection method that Wang Kuang could think of. In fact, he was also guarding against it. Since that thing appeared in Cao Cao in Huarong Road, since it appeared in the form of a luminous stone, Wang Kuang did not believe that someone would be so bored, so bored that he threw him over a thousand years ago, and then joked with him. But, not afraid of ten thousand, but only in case, the so-called intention to harm others should not be without the intention to guard against others. Before knowing who the other party is, it is better to be cautious.

Since Jian'an City has built houses almost every year, and the city walls are improved step by step according to Wang Kuang's original idea, so the chiseled bluestone is mostly the ones that were carved out after Wang Kuang led to the place where the secret room was built. After Wang Kuang led him to plan, he went out and walked around. Behind him, there were a lot of people with carts and small cars, all of whom were carts and carts transporting the chiseled bluestone. These were all sent by the people of Jian'an when they heard that the little boss wanted to use it, so they sent it directly. I won't talk about the money or not. It hurts the feelings.

Digging pits and building walls are all very fast. Even when Wang Kuang suddenly thought of preventing radiation, he suggested that a layer of lead should be filled with six sides. The craftsmen successfully asked for more than a thousand kilograms of lead from the salt iron official, but it did not melt. He directly built another wall, smashed the lead and then smashed it into a gap nearly a finger wide between the two walls. They thought that the little boss was for waterproofing, so they naturally would not say anything. The ductility of lead is not worse than gold. Not to mention one finger wide, it is just a seam as thin as hair. After being smashed with lead wire, it is tightly fitted. The stones on the dams in many places were cracked, seeping water, or water in the mine holes seeped out from the cracks on the rocks on the walls of the caves. This method is used to repair it.

In more than half a day, the secret room was built. Such a construction speed was a miracle. If people from other places wanted to build such a stone room, they would not even think about it. Only Wang Kuang, who was very popular in Jian'an, would need anything. The craftsmen went out to go around and told me that the little boss wanted to build a house. What was missing? It would be possible that Wang Kuang would have collected everything in a moment. If it weren't for Wang Kuang's consideration that the secret room could not be too ostentatious and did not let someone come to help, I guess those people in the entire Jian'an City who had nothing important at hand, regardless of the old or young, men and women, would have come to help.

The glass of the observation hole had been burned and sent here. Wang Kuang did not require a high level of flatness. He only asked to see whether Cao Cao was returning to the right position. As long as there was a shadow and a contour, it would be possible, so it burned very quickly.

"Try it?" Xu Guoxu also saw the Huarong Dao taken out of Wang Kuang's hand, and also saw Wang Kuang take out Cao Cao from it, so he naturally recognized it. The size and thickness of this Cao Cao was the same as the pit on the luminous stone. In addition, Wang Kuang wanted to build such a secret room, so he knew that Wang Kuang was going to try to inlay. But in Xu Guoxu's eyes, Cao Cao was still Cao Cao, and he was still a small square made of wood. If there was something strange, the only font was a bit weird, and nothing else was left. Therefore, his mind suddenly raised his mind with such careful attitude towards Wang Kuang. If this thing was really combined, what would happen? Eat people? Swallow them? Or suddenly spew out the samadhi true fire or poisonous miasma mentioned in the legend?

"Try it." Wang Kuang smiled, turned around and went down the steps, entered the secret room, pushed open Xu Guoxu who wanted to follow in, and then closed the door of the stone room. Because there was a small room alone, there was no need to be made of stones. In that case, it would not be built in less than half a month. The heavy stone door switch mechanism is a technical job.
