People in Datang have been expelled from school

Li Lizhi was about to say something when Li Zhi hurried over and interrupted the conversation between the two couples.

"Teacher, Tie Da has finished the boiler and is sending it to the printing workshop now."

"I gonna go see."

After speaking, Li Zheng stood up again.

Li Lizhi knew about the boiler and Li Zheng took it very seriously.

According to Li Zheng, the boiler is the key to break the current productivity bottleneck in Jingyang.

Li Lizhi swallowed the words she wanted to say, and could only watch Li Zheng leave.

Xu Hui walked over with tea and said, "Your Highness, the tea is just brewed."

Li Lizhi nodded and took the tea and said, "Father, Queen Mother, have you received my letter?"

Xu Hui said in a low voice: "The queen was quite relieved after receiving the letter, saying that she is now waiting to hold her grandson."

Li Lizhi is the most beloved daughter of His Majesty and Empress.

Both His Majesty and Queen are very concerned about Li Lizhi's current life.

Moreover, among the princesses in the palace, only Princess Changle and Xiao Sizi are the two prostitutes.

Princess Changle is the most honorable princess, and Li Zheng is the richest person in Guanzhong.

Xu Hui really couldn't imagine what would happen to the children of Princess Changle and Chang'anling in the future.

Li Lizhi lowered her eyebrows and looked at the tea in the cup and said in a low voice, "Have someone prepare some money. We will sort out all the money in our treasury. We will need a lot of money in the coming days."

Over the past ten years, Li Zheng and Li Lizhi have saved a lot of money.

Although the various workshops need to spend money to buy materials, the farms also need to buy old grain from Lingnan for feed.

But these costs can be turned into profits, and they have been paid back in the past few years.

In addition, Princess Changle and Chang'an Ling lived a simple life on weekdays.

And don't squander money.

The more money he saved, the ones buried underground in the backyard, and the three storerooms were full of money.

Not to mention that the silver mines sent from the Western Regions are still piled up and have not been refined into silver cakes.

The money alone is more than a million guan.

Li Zheng followed Li Zhi all the way to the printing workshop.

Dozens of logs are used to support the boiler, and seven or eight strong men in the village are struggling to send the boiler to the printing workshop.

Li Zhi hurriedly stepped forward to direct.

Many people in the village came to watch.

Kong Yingda also watched this scene. He walked up to Li Zheng with a cane and said, "Son, is this the power you mentioned?"

Li Zheng didn't deny it and said, "This is part of it."

The previous assembly line of the printing workshop was driven by both manpower and water power.

After using the boiler, the original cumbersome water power and manpower can be discarded.

The heat generated by the combustion of the boiler is used to drive the wheels above the boiler. After the wheels turn, they can pull the rotation of the assembly line through various transmission joints.

Li Zhi directed the boiler to the ground.

The three brothers of the Tie family were busy installing all the joints of the printing line to connect the boiler.

In order to make room for the boiler, it has been specially rebuilt during the period of shutdown during the Chinese New Year.

Now it's much easier to just put it on.

After working for a long time, the boiler can be regarded as the transmission device connected to the assembly line.

Daniel and Li Zhi are doing the final inspection.

Kong Yingda said: "Since you said that the power is not just the boiler, what are your other strengths?"

Li Zheng said: "It's like knowing a formula. With this formula, mathematics that could not be solved before can be easily solved. Industry is like this. It is a door. Open this door. There are many treasures in it. When treasures are mastered by people, things that could not be done before can be done in the future."

Hearing this, Kong Yingda stroked his beard and said, "It's like when a person's understanding has reached a certain level, he can also understand things that he didn't understand before, and do things that he couldn't do before."

"Almost the same meaning."

"I still have a question."

Li Zheng looked at him and said, "Excuse me, old master."

Kong Yingda whispered: "Then do you know how to grasp those treasures? What are the things that cannot be done?"

Li Zheng smiled, "How do I know?"

"You just don't want to say it."

"Then it's because I don't want to say it."

Kong Yingda sighed: "I still remember the first time I saw you in the Imperial College ten years ago, when you were still a brat."

Recalling the beginning, Li Zheng smiled awkwardly.

Kong Yingda added: "At the beginning, I felt that you were a very special child. Many times you behaved the same as others. That was because you deliberately let others see. At that time, you said that the ground was round, so I should Understand, in fact, you look at everything in the world differently from ordinary people.”

"may be."

Li Zheng had a smile on his face.

Daniu and Li Zhi have confirmed that there is no problem with the installation of the boiler, and have started burning coal for trial use.

Kong Yingda continued: "Can you now tell me the riddle from ten years ago?"

Li Zheng said in a low voice: "Actually, we live on a sphere. This sphere rotates on its own axis and revolves around the sun. That's why there are sunrise and sunset, day and night, year and seasons, and the land under our feet has land. Gravity, it is attracting everything, I can stand on this ball, so there will be stars in the sky falling on the ground."

"Why didn't anyone find out?"

"Because all this is our cognition, we think that the ground is flat when we step on it, and we think that the stone will fall, so we naturally think that the stone is heavy, but we don't think about why it falls."

Kong Yingda sighed, "Is this the way you see things?"

Li Zheng said: "Break out of the usual way of thinking, don't accept death, don't take it for granted, think more and ask more."

"Think more, ask more."

Kong Yingda smiled and nodded, "Although I don't know if what you said is right or not, I believe that one day in the future, the world will understand the truth."

After he finished speaking, he looked at Li Zheng, and Kong Yingda said in a low voice, "Li Zheng, the old man is right."

Li Zheng nodded solemnly, "The old master is right, people in the future will understand."

The operation of the boiler was very smooth, and without any manpower or hydraulic power, the conveyor belt and printing rollers in the printing house started to rotate automatically. Although the speed was not high, this was already a great improvement.

After three days of successful boiler operation.

Li Zheng sat up from the bed tiredly.

On the contrary, Li Lizhi was already sitting aside, dressing up.

Ignoring that the couple were in the room, Xu Hui hurried to the study and said, "Chang'an Ling, something happened to Her Royal Highness, Mr. Kong Yingda is in the academy, he...he passed away."

Hearing this, the comb in Li Lizhi's hand fell to the ground.

Li Zheng got dressed and ran out of the house, all the way to the academy.

At this moment, the academy was full of people, and no one was talking. They were all looking at Kong Yingda who was sitting kindly on the chair. He was still holding a book and pen in his hand.

Kong Yingda's granddaughter knelt aside and wept.
