Li Zheng took out another drawing and handed it to Xu Jingzong and said, "Take this drawing to Duan Lun of the East China Sea, and the future sea ships will be built according to this specification."

Xu Jingzong took the drawing and said, "I understand, let's make arrangements."

Xu Jingzong, who had taken the drawings, hurried to do his business.

Li Zheng looked up at the gray sky, and the snow was still falling.

The scenery in the distance is already covered with snow.

When I got home, the little rhinoceros in thick coats were piled with snowmen.

My little face was so cold that it was red.

Li Zheng walked into the house and sat next to the stove to keep warm.

Li Lizhi had nothing to do today and whispered: "Have you met your father?"

Li Zheng nodded and said, "I have seen it."

Li Lizhi sat down and asked, "What have you said?"

It was a cold snowy day outside, and the home was much warmer.

Li Zheng said: "It's nothing, it's just asking about your well-being and warning me not to rebel."

Li Lizhi smiled and said, "I don't believe that my father told you all this."

Holding a cup of hot tea, Li Zheng looked into the distance, and occasionally he could see a few busy figures in the snow.

After sitting for a while, Li Zheng stood up and returned to his study.

It is not difficult to use boilers on sea boats.

The drawings that Xu Jingzong gave to Duan Lun were also drawings of boilers and sea ships in later generations.

When Li Zhi's boiler is completely built, it will be placed on the sea boat.

Of course, the boiler must be used in other places, which will increase Jingyang's productivity by a lot.

After sitting in my study for a while, the wind and snow outside had stopped.

But the sky is already gray, and it seems that the snow will continue to fall.

Li Zheng came to the door of his house and looked at the blacksmith shop in the distance. The sound of the boiler whistle sounded very loudly and quickly.

After the whistle sounded, the boiler began to operate and thick black smoke came out of the boiler mouth.

After a while, the boiler emitted the sound reinforcement.

The boiler shook a few times and then there was no movement again.

On heavy snow, Li Zhi was still busy and sweating profusely, and his clothes were already blackened by the black smoke from the boiler.

As if he noticed Li Zheng's gaze, Li Zhi turned to look at Li Zheng.

He simply put down his work, Li Zhi walked to the door of his house and sat at the door of his house like a child exhaling his anger.

Li Zheng said: "Your Highness King Jin, nothing happens overnight. You often have to learn from failure."

Li Zhi said distressedly: "How many times have you said this? The boiler's tolerance is too poor, and the wheels next to the boiler cannot be carried."

After saying that, Li Zhi handed it to Li Zheng according to the drawing and said, "Look, what other solutions are there."

Li Zheng looked at Li Zhi's drawings and said, "Why do the transmission need gears?

Why not try the tracks.”

Li Zhi thought about it and said, "Crawlers?"

After thinking for a while, Li Zhi said: "The transmission of the gear requires a lot of kinetic energy, the friction of the gear consumes more kinetic energy, and the gears are more likely to wear. If you use a track, it is easy to replace the track. Not only that, it can save a lot of kinetic energy, save a lot of parts, and reduce unnecessary failures."

Li Zheng nodded, "The wisdom of His Highness King Jin is really admirable."

Li Zhi stared and stood up and pointed at Li Zheng and said, "You knew from the beginning, right?"

Li Zheng smiled and said, "Why did Your Highness the King of Jin say this?"

Li Zhi shouted: "You have known what I did wrong. Did you torture me on purpose?"

Li Zheng said: "Your Highness King Jin is crazy about studying boiler devils. Here we suggest that Your Highness King Jin stop working for a few days to rest."

Li Zhi snatched his drawings and looked at Li Zheng's face again: "If it is not done well after this time, I won't make a boiler, and whoever wants to do it will do it."

After saying that, Li Zhi returned to his room angrily.

Little Aizi asked curiously: "What's wrong with the emperor?"

Li Zheng said, "Your brother has an epiphany at this moment."

"Epiphany?"

Little Shizi looked at Li Zheng with a puzzled look on her face.

Li Zheng said: "The things you created by your royal brother will change a lot. Of course, this thing will be the first to be used in Jingyang. That is the power of knowledge and power that those people cannot understand."

Knowledge is power, and I have never missed this.

What changes the world is knowledge, and what is used to explore the future is also knowledge.

Li Zhi returned to his room and probably wouldn't come out all day after he went in.

Xu Hui brought a basket of green vegetables and said, "The greenhouse vegetables this year are good."

Although it is winter and the weather is very cold, the light is long this year, and with greenhouse insulation and light green vegetables, you can grow well.

During dinner, the whole family sat at the table and ate around a large hot pot.

Li Zhi ate two bites of mutton hotpot, then cleaned the rice in the bowl and returned to his room.

Seeing that Li Zhi was in a hurry to eat again, Li Lizhi sighed.

It seems that sitting at the dining table for a while is a waste of time for Li Zhi.

It started snowing outside the house at night.

Li Jiangshan rarely stayed at home tonight.

Seeing her sleeping by the stove holding a horizontal knife, it was the first time she saw her sleeping. Li Zheng looked at her for a long time and thought that when he approached her at this time, would she draw her sword?

"What are you watching me do?"

Li Jiangshan suddenly opened his eyes and said.

Li Zheng withdrew his gaze and said, "I'm wondering if you want a bedding."

As soon as he finished speaking, Xu Hui held a bedding and handed it to Li Jiangshan and said, "This is arranged by His Highness the Princess."

Li Jiangshan didn't hesitate to take the quilt and covered her body.

Li Zheng returned to his room, took a sip of hot tea and went to bed.

The next day, the snow stopped, and Li Zheng carried a hoe and went out early. Now this is when the snow stopped and the coldest time.

Even the air I breathed could feel colder than yesterday.

There are already villagers in the fields busy.

When the snow melts, it will also cause frozen soil to form on the ground.

This kind of permafrost is especially in fields, which can also harm crops that have been cultivated in the coming year.

At this time, we must turn out the frozen soil, and after the snow is completely melted, the land will be fertile in the next year.

Li Zheng waved his hoe to shovel the frozen soil on the ground.

Li Ji walked out early in the morning and said, "It's so cold today."

Li Zheng said: "The General came out for a walk so early?"

Li Ji said with his muscles and bones, "Doctor Sun said that you should exercise more when you are old. This will be of great benefit to me. You must live longer so that I can watch you. What if I rebel as soon as I die, what should I do?"

Li Zheng smiled and said, "The General really loves to joke."

Li Ji shook his arm and said, "You should continue digging the ground, I will walk around by myself."

Li Zheng waved his hoe again and saw Li Zhi hurried to the blacksmith shop with the drawings.
