Wang Juan missed the exercises at that time. The only difference between them and real wars was that the soldiers did not face the oppression of death.

Anyway, I know that even if I die, I will pretend to die, except for those who accidentally fall to death.

That's much more fun than the sand table now and costs more, unlike now. Just get some money.

At that time, the satellites in the sky really needed cooperation. After the two sides contacted each other, the first thing they started was electronic warfare, then long-range warfare, and finally annihilation war.

If there are really bullets outside the tanks, rocket launchers and other cannons, they will not explode and will send out electronic signals. If there are enemies around the place where they fall, there will be analog signals of shrapnel flying according to irregular signals. If you are injured, you will be injured. Some functions cannot be used. If you are killed, you will be withdrawn from the battlefield.

A protective helmet on your head, and even if the shells fall on your head, it will not easily die. Unexpectedly, you are sniping on a tall tree. Suddenly, a shell falls on your head and smashes you down. Then... the death quota has your name.

However, the current sand table deduction judgment is improved no matter how it is improved, there are always loopholes, and the ability of individual soldiers to fight cannot be reflected.

For example, if you determine the encounter, one party uses a bow and arrow and a flying knife, and the other party uses a gun. If you make a normal judgment, the one who holds the gun will kill you at a certain distance.

However, in reality, there may be a situation where people who use bows and arrows and flying knives can get close to you and kill you with a flying knives.

A small team of elite troops can even determine the success or failure of a local tactic. The sand table cannot perform accurately, which is far behind.

The simplest example is to ask Zhang Xiaobao to lead the Miao Guardian team to cooperate tactically. When the opponent has guns and cannons and one side uses cold weapons, the 100 team led by Zhang Xiaobao can appear, which will completely defeat the opponent's 300 or even 500 people.

The personal qualities of soldiers are not the same. How do you reflect them on the sand table? Will you let everyone compete again?

Therefore, while Wang Juan made rules, she regretted that she could only try her best. It was better than two people talking on the left and right side of the sand table.

Li Longji didn't know Wang Juan's regrets. He thought it was already very good now. Whether he had the ability or not could tell at one try.

Arrange people immediately to notify the generals and ask them to prepare for the written examination.

Zhang Xiaobao and Wang Juan left with satisfaction.

The generals were stunned after receiving the emperor's notice. They were just wars, so why did they have such a relationship with the people? Is it a joke?

Zhang Xiaobao had no time to consider what the generals thought, so he came out of the palace with Wang Juan and went straight to the Ministry of Works to find Zhang Xiaobao's father Zhang Zhong to discuss the family's business expansion.

Before the Ministry of Works, they received news that Zhang Zhong was not in the Ministry of Works, but went to the place where the martial law experiment of the Ministry of Works outside the city. The two of them looked for a carriage and turned outside the city.

When we arrived at the place, many people gathered there to watch the fun.

Zhang Zhong was also in the crowd, holding a telescope in his hand and looking at a diesel engine two hundred meters away.

When Zhang Xiaobao and the others approached and took the telescope from their hands to watch, they saw that the diesel engine was operating normally, making a sound that deafening. The other end was not connected to a hand-held tractor, but a lathe.

The shaft on the lathe is connected to the diesel engine. As the diesel engine rotates, the turning tool on the lathe also rotates, and the blade is painted with color, one small dot and one small dot.

Zhang Xiaobao saw coils, and after looking at them for a while, he felt like he was turning in reverse, just like a wheel, which was clearly rotating forward, but the lines formed by the holes on the wheel were rotated backwards due to rotation.

It is a visual deception, a very common thing.

Next to the lathe, there was a cabinet, oh, no, it was a man, wearing armor made of unknown metal, and approaching the knife with an iron rod in his hand.

Zhang Xiaobao understood that the armor this man wore was to prevent the knife or iron rod from collapsing, and to prevent the diesel engine from exploded. It was really not easy, hero.

Everyone was watching, watching the man touching the iron rod to the rotating cutting knife, and the iron rod broke with a spark.

When we were on time, a burst of cheers broke out in the crowd, which made Zhang Xiaobao and Wang Juan feel that the noise of the diesel engine was not very big.

The man picked up the broken iron rod on the ground, held it together with his hands, and ran towards the crowd, but his movements were clumsy. He ran out for more than ten steps, and his feet were unstable, and he fell to the ground with a rumbling sound.

Immediately, someone who was not afraid of death rushed over and pulled the man back.

After helping to take off the 'clothes' on this person, everyone then watched the two broken iron rods that were cut open.

Zhang Xiaobao and Wang Juan also came forward and watched together.

After learning, everyone did not foolishly touch the broken mouth with their hands, knowing that it was so hot.

"It's not bad, the blade edges are very uniform, the cut surface is smooth and flat, which means the blade does not have too large concave convexity on the horizontal plane." Zhang Xiaobao commented after looking at it.

Wang Juan nodded. The most intuitive thing about the cutting knife is reflected in the cut surface of the cut object. Looking at the iron rod in front of you, the steel mouth is pretty good, but I don’t know how worn the cutting knife is.

Hearing Zhang Xiaobao's words, Zhang Zhong realized that his son and his daughter-in-law were coming. He hurriedly pulled his son over and introduced: "Xiaobao, look, this is the steel just made from the blast furnace. It is very hard. It takes a lot of effort to break it with normal cutting methods, and the incision needs to be re-sanded.

People from the Ministry of Industry were wondering whether they could use diesel engines, but the result was really done. Look, look at the cut, it is flat and smooth, and it can improve a lot of efficiency in the future. The diesel engine is not very stable. We plan to produce more such steel and then use it to make diesel engines."

Zhang Xiaobao nodded and expressed his understanding that industry is like this, promoting each other, turning back and forth, such as lathes, first hand-made parts as fine as possible, and then using lathes to use more precise parts on the lathes, and then repeated back and forth, updating from generation to generation based on the same improvement of materials.

Nothing can be created out of thin air without the development of the system.

"Dad, it's time to stop the diesel engine." Zhang Xiaobao reminded.

"Stop? You can't stop. Let's talk about it when the oil is burned. After it is burned, it will stop by itself. If it is not burned and suddenly it breaks, we can know where something went wrong." Zhang Zhong said to his son.

Zhang Xiaobao looked at Wang Juan, and Wang Juan blinked. She knew how the money was spent. She also admired the technicians of the Ministry of Works even more. Although she knew that it was not easy to build a diesel engine, she still hoped that the diesel engine would have problems.

It can be said that it is another version of worrying about the cold weather.

Creating over and over again, experimenting over and over again, moving forward step by step, boldly thinking, and carefully proof, this is the scientific spirit.

Except for their lack of theoretical knowledge, they are no worse than academicians of the Academy of Sciences in terms of research.

Zhang Zhong was still excited and said to his son: "For some new steel, we can make better cutting blades, and the lathe should be replaced. Xiaobao, come here..."

Zhang Zhongcai remembered that his son didn’t come here very much, and it must be something that he found here today.

Zhang Xiaobao's father has definitely begun to change from an administrative staff member to a technical staff member. Wang Juan has never taught his father any more, and he has learned a lot.

Reply: "Juanjuan and I discussed it and planned to expand our business at home, open more branches, and go to the Ministry of Industry to see the waste."

"Scrap? Is it possible that the branches also need to make steel?" Zhang Zhong asked in surprise.

Zhang Xiaobao waved his hand and said, "That's not the case. I think, no matter how bad the waste in the Ministry of Industry is, it is better than the farm tools outside. If you want to make some sets of things that people can use normally, you can sell them, so that the Ministry of Industry will have less waste.

Many things don’t have to be re-cooked. For example, if the cutting blade collapses, the quality is indeed not good. Compared with the requirements of the work department, it is still fine to use the fragments inside to grind out some of the engraving knives."

Zhang Zhong thought for a while: "That's right, but parts cannot be sold casually, especially those with shapes, which are easy to get people to go there. If you open a branch at home, please pay attention. If you encounter meteorites outside the sky, you must take them back.

As you said, there may be very good alloys inside. Our Ministry of Works will take a look. We will pick the useful ones and make new parts. Xiaobao, can the newly refined steel be used for the cold rolling you and Juanjuan mentioned?"

Zhang Xiaobao's eyes suddenly widened, "I dare to think about anything, I'm still cold-rolled. Is there any stamping equipment?"

Wang Juan took over: "Dad, it's not working yet, so it's better to heat calcinate. Wait until the smelting technology is improved and see if it has the ability to make large stamping equipment. Things need to be done little by little. Let's propose a theory, and everyone discusses it and don't be anxious.

When we go back to find a way to find meteorites, we actually ask the people from the Ministry of Works to mix different metals together in different proportions, and smelting and forging materials with different properties may also appear, such as very hard, easily plasticized, etc.

Since we have already made our efforts to make money and don’t feel sorry for spending, we should experiment hard. A small step in every project is a big step in the industrial system.”

Zhang Zhong couldn't hide the disappointment on his face, but he still responded: "Oh, okay, as Juanjuan said."

After all, the daughter-in-law is the "professional", and Zhang Zhong firmly believes in this.

Wang Juan was very embarrassed, is he professional? It seems that his major is not like this. After thinking about it, he said to Zhang Zhong: "Dad, isn't oil separating various materials? You can put it in various oils when annealing steel, debug the temperature and see how it works."

"Can you still put it in the oil?" Zhang Zhong heard it for the first time.

"Try it, maybe there is a really unexpected surprise." Wang Juan said.

"Okay, anyway, we have a lot of money, various materials and various mixing methods, so we don't believe that we can't find good things. We can also miss one or two, right?" Zhang Zhong made up his mind.

Zhang Xiaobao quickly agreed: "Yes, yes, dad, you are right. Science has developed through unexpected events that have been tried again and again. Of course, we have to figure out why we should do this. First, we must analyze the good things we miss."

"I know, I know, there are experimental records. If the records cannot be repeated, it means that we have some key things missing." Zhang Zhong looked like a scholar.

"Yes, Dad is right, then Dad, let's talk about it here. Juanjuan and I will reply first, and then summarize the theory to see if we can make something better."

When Zhang Xiaobao saw his father talking to him, he always glanced at the diesel engine and lathes in the experiment. He knew that his father was not focused on him, so it would be better to leave quickly.

"Xiaobao, go and Juanjuan and let me take a look." Zhang Zhong waved his hand.

Zhang Xiaobao and Wang Juan left, walked through layers of defense circles, and stood at the foot of the mountain.

Looking at the coachman who was napping on the shaft, Wang Juan asked: "Xiaobao, do you think that if science develops, will many people be unemployed, such as this coachman?"

"How is it possible? The more science develops, the more detailed the industry will be, and the more people you need. It's just that the technology has become stronger. Can the driver who drives the car go and drive."

Zhang Xiaobao is not worried about such things. The so-called inability to find a job is relative, not absolute.

Anyone who cannot find a job dislikes the poor job that can be done easily and the low income is not a problem of strength, but a problem of concept.

"Yes, there are not many people in the Tang Dynasty now, so I'm worried too much. Let's go and go back." Wang Juan no longer thought about this matter.

Wake up the driver and take the car back home.

Xiao Bei and his group of children are already packed up and are reading books. If you don’t understand, ask each other first. No one knows how to remember. They will wait until their brother and sister come back before learning.

Because Xiao Bei's development direction is different, he has not learned much now. He quickly memorized what he should be memorized and told stories to Li Jun and Pan'er.

The two little guys are over two years old. They like to listen, point at things and ask, and they also like to run over and take a closer look when they see something. They are serious and seem to want to do an atomic analysis of the thing.

After seeing it, they found it was not fun, so they ran to another place and threw a ball on the ground. They could run along for a long time and were very happy.

Under the temptation of candy, the two children are now staying by Xiao Bei's side and listening to Xiao Bei's sister telling stories.

At this moment, Xiao Bei finally knew how difficult it was for his brother and sister. He knew what he knew, but he couldn't let Li Jun and Pan'er understand it. He had to become as stupid as them, and telling stories turned into teaching vocabulary.

"Ball, ball, is rolling, far away, ball, ball, rolling, look, isn't it?" Xiao Bei organized his words in embarrassment, holding a ball in his hand and throwing it around the ground.

The two children were obviously more interested in the state of rolling the ball. As for what they were doing, they might be able to learn a few times after playing with the ball.

"I'm so stupid, so stupid. It's too hard to teach them two." Xiao Bei sighed to the sky.

Xiaohai turned his head and looked at his sister, saying, "Brother and sister have never said we are stupid. We also grew up from this time."

"Okay, I won't say that they are stupid anymore, they are all smart. I can't remember what happened like theirs. It seems that I can get what I know naturally. What's going on?"
