People in Datang have been expelled from school

Chapter 1180 The First Boiler Experiment

Now the Potala Palace is about to be completed, and the palaces are basically completed. The construction that took several years is about to come to an end.

In the Potala Palace, Lu Dongzan and Songtsan Gampo talked about the recruitment of herdsmen.

After listening to Lu Dongzan's narration, Songtsan Gampo said, "How many herdsmen does Movo have now?"

Lu Dongzan thought about it and said, "Not many, even if they recruit another thousand herdsmen this time, they will only have three thousand herdsmen in their hands."

Songtsan Gampo thought about it and said, "It seems that Li Zheng has good intentions."

Lu Dongzan frowned and said, "What do Zanpu think?"

Songtsan Gampo said with a long sigh, "They want children from Tubo, not real herdsmen."

It is rare to see how Songtsan Gampo paid attention to the affairs of Tubo. It seems that Songtsan Gampo did not give up Tubo completely.

Being able to see Zanpu like this, Lu Dongzan was relieved a lot.

Lu Dongzan whispered, "Do we need to do something?"

Songtsen Gampo closed his eyes again and said, "Are we going to stop our herdsmen from going to their territory?"

Lu Dongzan was also silent when he spoke, and there were more and more conflicts among the herdsmen.

Songtsen Gampo said in a low voice, "Let's wait and see what happens."

Lu Dongzan stood up, although he didn't understand what Songtsan Gampo was thinking, but he finally saw that Zanpu was able to care about the affairs between the tribes.

When he walked down the Potala Palace, Lu Dongzan couldn't help feeling sad when he saw more and more Tubo monks. Maybe in the future there will be fewer and fewer Tubo warriors, but there will be more and more Tubo monks.

Looking up to the east, Lu Dongzan wondered what Li Zheng was doing now.

A cold monsoon blew by, and it was already winter before we knew it.

Lu Dongzan tightened his clothes and stepped down the Potala Palace.

In Jingyang, a huge boiler was dragged out of the blacksmith shop. This boiler was taller than the height of a grown man.

The entire boiler glowed with metallic luster in the sun.

Li Zheng and Li Tai watched from a distance as Daniel and Li Zhi and a group of college students were busy working around the boiler.

Li Tai looked at the boiler and said, "Is this the result of the past few years?"

Li Zheng nodded with emotion and said, "His Royal Highness King Jin didn't think about tea and food in order to create this thing, and he was about to go crazy."

Li Zhi started from the most basic physical effects at the beginning, and then began to study the mechanics of the interaction of forces, and studied the transformation of kinetic energy.

This period went through three or four years.

There are also two or three huge gears attached to this boiler.

As the boiler was ignited, a loud whistle sounded.

The sound of the whistle is very sharp and loud, and can be heard in a radius of several meters.

The boiler started to operate, and as the charcoal fire burned, the chimney of the boiler began to emit smoke, and then the gears of the boiler began to rotate.

Li Zhi's eyes were filled with excitement.

After a while, the movement of the boiler gradually became smaller, and the gears stopped turning.

A group of excited students also calmed down and began to look for the problem.

Li Tai looked at these from a distance and said, "How useful do you think this thing is?"

Li Zheng grinned and said, "You will know later."

After the boiler stopped working, Daniel and Li Zhi began to discuss with the drawings.

It seems that there are still some problems with the boiler that was built for the first time.

It's pretty good to be able to do this.

A gust of cold wind blew by, and it was time for winter in Guanzhong.

Li Zheng looked up at the cloudy sky and said, "I'm afraid it's going to rain."

Li Tai also said: "I haven't confiscated my change of clothes in the academy, so I went back first."

After Li Zheng returned home, the rain began to fall.

There are also fine snowflakes in the rain.

This kind of rain is very cold, and it hurts a little when it falls on the face.

Li Lizhi was sitting at the door of the house with a cup of hot tea and was teaching Xiao Si how to write.

Li Zhi also hurried back home.

As soon as he entered the door, he saw Li Zhi's resentful eyes.

Li Zheng drank his tea calmly.

Li Zhi moved closer and continued to look at Li Zheng with resentful eyes.

After being quiet for a while, Li Zhi finally couldn't help but said, "Don't you want to say something?"

Li Zheng looked at the drizzle outside and said, "It's winter, and the vegetables in our village's greenhouses can be prepared."

Li Zhi said: "What I want to say has nothing to do with the weather."

Li Zheng took a sip of tea, glanced at Li Zhi and said, "What does His Highness King Jin want to say?"

Li Zhi put the blueprint in front of Li Zheng and said: "There is a problem with the boiler, it stopped running after half a stick of incense."

Li Zhengchang sighed and said: "There is a saying that failure is the mother of success, and His Royal Highness King Jin will get closer and closer to success if you fail a few more times."

Li Zhi pointed to the map and said, "Then tell me what went wrong."

Putting down the teacup in his hand, Li Zheng said: "The charcoal fire His Royal Highness King Jin used to burn the boiler may not have enough firepower. If it is replaced with coal, the effect may be better."

Li Zhi thought about it and said, "What you said should also make sense. Coal is more resistant to burning and has greater firepower."

Li Zheng also said: "Ordinary coal mines need to be crushed to remove impurities before they can be used. However, this step pollutes the environment and is not good for the human body. I still don't recommend it."

Li Zhi thought about it and said, "Even if it's another kind of fuel, the firepower of coal is greater, and the pressure in the pot will be greater."

Li Zheng nodded slightly, "Then, does His Royal Highness King Jin understand the boiler problem this time?"

Li Zhi looked at the drawing and said, "Insufficient combustion leads to insufficient internal pressure in the pot. Once the gas valve is opened, the pressure in the pot overflows rapidly, and the pressure in the pot weakens, causing the boiler to stop operating."

"His Royal Highness King Jin is quite proficient in summarizing the reasons for the failure."

Li Zheng nodded in relief.

Li Lizhi, who watched this scene, suppressed a smile, and Li Zheng was short of saying that a child can be taught.

Li Zhi also said: "If you want to change a kind of fuel, you need to make some changes inside the boiler, and the size of the gas valve of the boiler also needs to be modified. Since it is replaced with coal, the heat generated by coal during combustion is higher than that of charcoal fire." , The inner wall of the boiler also needs to be thickened, and the seal also needs to be strengthened.”

Wanting to play these games, Li Zhi held his forehead in distress and said, "This is equivalent to tearing down the entire boiler and starting over."

After speaking, Li Zhi looked at Li Zheng again.

Sensing Li Zhi's gaze, Li Zheng said, "Your Highness, Prince Jin, don't look at me like that. You designed the blueprints yourself, and you asked Tie Da to make the boiler yourself. If you fail, you can't blame me."

Li Zhi said: "The most critical part of the drawing is what you gave me."

Li Zheng sighed and said: "That was just a flash of inspiration I came from based on the teapot. It is all thanks to His Royal Highness Jin Wang himself that I can make the boiler."
