Standing at the door of the courtyard, Li Zhao and He Yuzhu looked at each other and smiled, both of them carrying large bags and small bags. is also Li Zhao's young age, and when he left the leader's house, he asked Li Zhao to bring out a lot of things, including meat, and scarce materials such as canned food, and He Yuzhu's is similar.

When you get home, marinate the meat first, otherwise it will stink the next day. In this era, since there are few refrigeration equipment such as refrigerators, it is quite troublesome to store food in the summer. In the past, large families had ice cellars where food could be stored, or food that could not be stored could be hung in wells, but this condition was not available in the courtyard.

For Li Zhao, there are only two ways to choose, one is to marinate with salt, and the other is to marinate with sugar, of course, don't think about sugar, he only has salt, and marinate the meat he brought back, which is enough for him to eat a lot of meals.

Now the courtyard is much calmer than when I first came, and the second and third masters were frightened this time, and their own problems were not so obvious. For example, the second uncle beating the child, I haven't heard much about it recently, although the third master is still always at the door, but there is no such thing as calculating things.

Uncle Yi and the Jia family are becoming more and more like a family, and they are busy educating the two children of the Jia family all day long, and they are also an uncle with a family background, and the two children are very close to them. Maybe it's because of his reliance, Uncle Yi doesn't care about things in the yard as much as before, and the number of times he comes to Li Zhao's house is also significantly reduced.

Xu Damao has already set off to open up the wasteland, without Xu Damao, it seems that there are more than half of the people in the yard at once, and the chase and fight scene with He Yuzhu every day is gone. He Yuzhu has been fighting with Lou Xiao'e recently, and he often can't see people, so He Yushui often goes to Uncle Yi's house for dinner, but Uncle Yi is quite welcome, because He Yushui often gives make-up lessons to stick terriers now, and it is not an exaggeration to say that Uncle Yi is full of smiles on He Yushui's face.

Just thinking about the things in the yard, He Yuzhu greeted him and came in, looking at He Yuzhu who was smiling, Li Zhao was also puzzled and asked, "What's wrong?" Laughing like a fool. ”

He Yuzhu asked a little awkwardly: "Brother Li Zhao, let me ask you about something, what do you say girls like?" I want to give Lou Xiao'e a gift, but I don't know what to give, so I don't want you to be a staff officer. ”

Li Zhao also beckoned He Yuzhu to sit down at this time, poured water for him, thought about it and Li Zhao said: "Actually, I can't say clearly, there are very few things that Lou Dong's family will lack, even if there is a shortage, he can't get it, and it is estimated that you will be enough." In other words, your family will basically not lack anything, so you need to find another way, give full play to your characteristics, and most importantly, be attentive. ”

Hearing Li Zhao say that it was his son-in-law, He Yuzhu's eyes lit up. In fact, Li Zhao was also a little embarrassed at this time, to be honest, if it was an ordinary person, it would be okay to say, just buy something and send it over. But for Lou Xiao'e, she doesn't lack any of these things, and it's hard to impress people. After thinking about it, Li Zhao continued: "Your carving is very good, can you carve wood?" ”

He Yuzhu replied without thinking: "It is okay to carve wood, this principle is the same, in the past, our cooks went to people's houses to cook, due to the lack of ingredients, they would also use wood to carve some things, such as fish or something, and put them on the table to make a good fortune." There are also some families who hold happy events, and there are also cooks who carve wild geese, and I have also learned some. What's the use of this? "Eight One Chinese Net

When Li Zhao heard this, he was also happy, and said: "It's easy to carve wood, you see that the Lou family is not short of things, and you have this craft, so why not carve something for her?" If you carve a wood carving of Lou Xiao'e and send it to her, won't this intention be there? Is it your carver who can do it? ”

Listening to Li Zhao's words, He Yuzhu was overjoyed, and hurriedly thanked Li Zhao, and then ran away in a hurry. At this time, Li Zhao secretly wiped the sweat on his forehead, breathed a sigh of relief, and said in his heart, how do I know what to send. If people are willing, it is good to give anything, and if they are not willing, it is wrong to send anything.

However, thinking of Lou Xiao'e, Li Zhao was also a little embarrassed, the probability of the Lou family going to Hong Kong Island in the future is still too great. Now that the Lou family has fallen in love with He Yuzhu, it is impossible for Li Zhao to run in front of others and say what the future holds, let the family run away first, right? If the Lou family doesn't run away, it will definitely be difficult to protect them. After thinking about it for a while, Li Zhao also had no clue, so he could only take one step at a time.

After sending He Yuzhu away, Li Zhao also sat at his desk and began to write down the plan. At present, the most important thing for Li Zhao is the production of a whole series of machine tools today. Li Zhao needs to write down the difficulties, key points and implementation process plans of these tasks for the convenience of later meetings.

You must know that this is a whole series of machine tools, with these basically the entire machining industry can complete a major innovation, and then based on these machine tools, you can develop a lot of special machine tools. For example, there are some places with extremely high requirements for the processing length, so the corresponding machine tool can be produced according to the requirements, but the main part of the machine tool is unchanged, such as the main chassis can not be changed.

In order to realize these machines, it is necessary to prepare a series of prerequisites. First of all, in order to ensure the performance, even beyond the design performance, Li Zhao is ready to directly use high-performance materials to smash. To take a very simple example, let's say that the pressure-resistant tank used in the hydraulic press needs to withstand hundreds of atmospheres.

In order to withstand this pressure, it is usually necessary to use pressure-resistant steel plates to wrap in multiple layers, and the wall thickness of the entire pressure-resistant tank even reaches tens of centimeters. This is also a very helpless thing, the material performance is not up to standard, can only use this method, generally up to more than 300 atmospheres, at least seven or eight layers of pressure-resistant steel plate wrapping.

But Li Zhao took out the pressure-resistant alloy steel used 60 years later, it was different, the same wall thickness, the pressure that can be withheld, can be increased several times. If you only need to achieve the current pressure level, you can use a thinner wall thickness, and the difficulty of processing will be greatly reduced when the wall thickness is reduced. Not only that, such a pressure-resistant steel plate can also be used in the pressure-resistant structure of the reactor, which will be widely used.

Speaking of high-pressure water pumps, if you want to increase the pressure of the water pump, in addition to the multi-stage pressurization structure of the water pump itself, it is the speed and motor power of the water pump. The motor power is good, as long as you want, you can basically configure the motor power arbitrarily. But if you want to increase the speed and pressure, the material requirements are stricter.

In this case, Li Zhao can use the high-strength and toughness steel in 60 years to produce these parts, in short, Li Zhao now has a variety of alloy steel bases, which can be very capricious design. Basically, under the same structure, Li Zhao can achieve better results than others.

Thinking of this, Li Zhao couldn't help but think of the hydraulic press, took out the drawings of the hydraulic press, and looked at the drawings, Li Zhao couldn't help frowning. The reason is very simple, Li Zhao did not plan to build such a large electroslag furnace, and when designing the hydraulic press, only a few key parts used alloy steel. For the most part, existing steel is still used, and the overall design of the hydraulic press weighs more than 2,000 tons.

In order to be able to process larger workpieces, Li Zhao increased the opening size to 7 meters and the height to 8 meters. The classic three-beam four-column mode is not adopted, but the eight-column mode is adopted, the reason for doing so is mainly to reduce the difficulty of processing, after all, the four-column mode, the diameter of each column reaches one meter, the processing difficulty can be imagined, and the eight-column mode can be greatly reduced.

Now that the electroslag furnace has expanded, then more parts can be replaced with alloy steel, in this case, not only can the overall weight be further reduced, but the performance can be further improved, the original design is 15,000 tons, then the use of alloy steel ratio increases, the index can be further relaxed, according to 20,000 tons to build.

Therefore, the first step is to build the electroslag furnace first, and in order to cooperate with the electroslag furnace, it is necessary to produce various added elements. In addition to that, there is the power plant, and near the rolling mill is the power plant, but this power plant is now limited in capacity. Originally, this power plant was aided by Da Mao, but last year Da Mao was withdrawn, and it is said that the construction of the power plant was not completed. Thinking of this, Li Zhao wrote down this matter and needed to take time to see the actual situation.

At present, the solution with the electroslag furnace is the power plant and the refinery of various elements, otherwise the electroslag furnace can only be used to refine metals. After these prerequisites are realized, Li Zhao can take out various alloys after 60 years, so that after the material properties come up, many problems will not be a problem. With excellent materials, many problems that could not be achieved in the past can be solved simply and crudely.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
