People in Datang have been expelled from school

That night, Kong Yingda's body was brought back.

I heard from the children in the academy that the old master Kong Yingda fell asleep while reading a book, and he couldn't wake up from this sleep.

Li Tai said to Li Zheng; "The old master is so old, at least he is enjoying his old age in An'an, and his granddaughter also has happy children."

I was still talking yesterday, but now I see that the person has left.

Li Zheng felt panicked.

Li Tai said: "The old man walks very quietly. It's not surprising when he walks at this age."

Listening to Li Tai's comfort, Li Zheng said: "I really hope they can live a long life."

Put Kong Yingda's body first at the residence of Kong Yingda's granddaughter.

Waiting for people from the Kong family to collect the funeral.

The imperial court also knew the news of Kong Yingda's death, and the palace came with a decree, "I will be gifted to Tai Changqing, with the posthumous title of Xian, and buried in Zhaoling."

It is a great honor for Kong Yingda to be awarded the posthumous title and be buried with Zhaoling.

The old village chief and Sun Simiao also came to visit Kong Yingda.

The three old men in the village, Kong Yingda, Sun Simiao, and the old village chief were the closest.

Li Zheng and Li Tai helped Cheng Chumo keep the spirit.

The village looks very quiet tonight.

Cheng Chumo said: "I didn't expect his old man to leave like this."

Li Zheng patted him on the shoulder, "Birth, old age, sickness and death are common things."

Cheng Chumo looked at the stars all over the sky, "I still remember that my old man wasted a lot of thought in order to let Kong Yingda marry her granddaughter to me."

This marriage is indeed rare.

Kong Yingda has always been a scholarly family.

And Cheng Yaojin was born as a martial artist.

It is not easy for the two to come together.

It was an unprecedented thing for Wufu and the scholarly family to marry by marriage.

At the beginning, everyone looked down on this marriage.

Under Cheng Yaojin's stalking, Kong Yingda finally betrothed his granddaughter to Cheng Chumo, and the two families became in-laws.

Facts have proved that Cheng Chumo is very kind to Kong Yingda's granddaughter.

The two families get along very well.

Kong Yingda's granddaughter is coaxing two children to sleep.

She and Cheng Chumo also have two children.

Cheng Chumo said in a low voice: "Do you think we will have such a day in the future?"

Sitting at the gate of the courtyard, Li Tai said, "Everyone has such a day. Isn't it the same when my grandpa passed away? Everyone has to face it."

The Kong family came the next day, and they took away Kong Yingda's body.

According to the rules, the granddaughters of Cheng Chumo and Kong Yingda had to see Kong Yingda off.

Li Zheng stood at the entrance of the village and watched a group of people carrying Kong Yingda's body go farther and farther.

Li Yifu came and said: "We have already bought a few officials, and they are willing to speak up and hand over more border fortifications to Jingyang."

Putting away his sad emotions, Li Zheng said: "Continue to arrange the next thing, let the people in the court know that our engineering team has the top construction technology of Datang."

"Here!"

Walking back to the village, Li Zheng walked on the path in the field. Now the children in the village have grown taller, and the first batch of children who learned the multiplication table from him back then have also married.

After so many years, Li Zheng now has a feeling of trance, time flies too fast.

It feels like so many years have passed by now.

Black smoke rising from the chimneys of the printing house showed that the boiler was working.

So far the boiler seems to be working fine.

The three brothers of the Tie family have already turned on their horsepower and started casting boilers.

Li Zheng found Yan Liben in the academy.

Kong Yingda passed away, and Yan Liben was not in high spirits.

Seeing Li Zheng coming, Yan Liben quickly stood up, "Chang'an order."

Walking into Yan Liben's room, not long after he came back, Yan Liben's room returned to a messy state.

All kinds of drawings are placed all over the place.

Some are helpless.

Yan Liben smiled awkwardly and led Li Zheng out of the room, saying, "This old man understands that numeracy and construction are inseparable. I didn't think so before, but now I think so."

Li Zheng said to him: "How is the formula applied?"

"I am much more proficient than before, especially geometric calculations, which are very useful in our artisan industry."

Lu Ban is the patriarch of craftsmen all over the world.

In Yan Liben's heart, he didn't want the artisans to stagnate.

If numerology can break the bottleneck of artisans, he is still willing to learn it.

Li Zheng said to him: "Master Yan also knows that I am now casting something called a boiler."

Yan Liben nodded and said, "That thing is really miraculous. I didn't expect such a miraculous thing to be created in the village these days after the old man left."

Li Zheng said: "It was all made by His Royal Highness King Jin."

While walking, Yan Liben said: "I don't believe that I don't have your advice from Li Zheng."

Li Zheng did not deny what Yan Liben said.

Yan Liben said with emotion: "The old man has studied this boiler and seen the blueprint of the boiler. It is a very complicated thing. If I let the old man do it, I will not be able to make it within a year or so. The boiler is as difficult as it is difficult." He combined the physics, mathematics, and crafts he learned in the academy, not only can he make it with a superficial understanding, but he also needs to learn physics and mathematics to a deeper level, otherwise he would not be able to make this boiler."

What Yan Liben said was correct. In order to create this thing, Li Zhi began to study mechanics. After studying power and then thermodynamics, Li Zhi almost became obsessed with learning.

Li Zheng stopped and said, "Actually, I came this time because I wanted to ask Master Yan for help."

"Say it straight."

"I want to build a processing factory in the village. Master Yan also knows that boilers are very difficult to manufacture. The current casting progress is still not enough, so I want to build several processing factories in the village."

"Processing plant?"

Li Zheng took out a roll of drawings and said, "It's just such a processing factory."

Looking at the drawings, Yan Liben saw something that he had never seen before.

Li Zheng smiled and said, "Can it be made?"

"It shouldn't be a big problem, but what are the small parts on it for?"

"The big rack is used to hold metal objects, and the wheel is actually a whetstone, used to sharpen metal parts, and the small rotor is used to thread and drill holes."

What Li Zheng didn't mention are tools for hardware work.

With these things in metal casting, it will be much more convenient in the future.

"It's not a problem to build a few houses, but I'm afraid it will take some days to make these small parts."

"Then I will trouble Master Yan."

Yan Liben waved his hand and said, "It's nothing troublesome. The old man came to you and learned all this knowledge. It's too late to repay you. How can you say it's troublesome."

Li Zheng still bowed slightly.

Seeing something that he had never seen before again, Yan Liben sighed, "It's true that there is no end to learning."
