Su Chen took Li Er with him, followed by civil and military officials.
On the other side, Si'er also held Queen Changsun's hand and pulled her towards the east end of the village, still chirping:
"Auntie, that steam engine is really fun. You can put some coal in it and it will run on its own. Brother Su Chen also made me a small bucket for it to pull Si'er and run."
Arriving at the east end of the village, Li Er looked at an ugly lump of iron lying on the railway track with a look of disappointment on his face:
"You want me to go out on a cold day, that's all?"
"Your Majesty, this is just a demonstration. It's great that it can be made in such a short time. It will take you a lot of time to build a carriage!"
Li Er frowned: "Didn't you say you can run?
Why don't you move?"
Su Chen nodded, and the craftsman came up to open the air vent and close the air valve...
The fire pit of the steam engine never went out, and the water in the boiler kept boiling.
After the furnace fire is burning, the steam will quickly rise. After the pressure is reached, it will start to output power...
As a large amount of water vapor is sprayed out, the steam engine drives the wheels to slowly move along the rails.
When Li Er saw that he could really run, he showed some admiration.
After walking a few steps, I found that I couldn't keep up, so I had to stand still and watch from a distance.
Si'er clapped her hands beside her and said, "Aniang, you look like you're running!"
The Minister of Civil and Military Affairs opened his eyes wide and saw an ugly iron lump with one pipe emitting black smoke and the other pipe emitting white smoke running past them.
?I didn’t see anything pulling in front of me. How could this thing run by itself?
Cheng Yaojin yelled and chased after him, and at the same time a group of other generals followed him.
"So soon?"
Li Er was not satisfied with the speed.
Su Chen said helplessly: "I told you that this is just a demonstration product. It is only used to demonstrate the principle of steam. And for the safety of the experiment, the speed is deliberately controlled to be slow."
"When a real steam locomotive is built, it will be so fast that it can run two hundred miles an hour."
Li Er asked: "How long will it take to make that one?"
"It's hard to say, I guess it will take half a year."
Li Er turned his head, and the steam engine had already come around from the other side of the village.
Si'er ran over: "Brother Su Chen, where is Si'er's little car?"
Li Er asked: "What little carriage?"
"Daddy, Brother Su Chen made a small carriage for Si'er. Si'er can sit in it and be pulled by the steam engine, just like riding a carriage. It's so fun!"
Li Er glared at Su Chen and said to Si'er: "Dad and the ministers will have to take a closer look at how this steam engine works later. I won't sit down today!"
Si'er had no choice but to agree reluctantly.
Seeing the steam engine running past him again without stopping at all, Li Er asked:
"How much longer can I run?"
Su Chen asked the craftsmen: "How much coal was added?"
A sturdy young man replied: "It's full!"
Su Chenzhao slapped him on the head: "You idiot, why did you add so much?"
The young man smiled honestly: "Master, you didn't say much, so I just filled it up!"
"Wait for the next round, go ahead and turn off the stove, be careful!"
Su Chen turned back to Li Er and said: "This demonstration product is not equipped with a control device. After a while, the air inlet of the stove is closed and it will slowly stop."
At this time, Changsun Wuji, Fang Xuanling and others came over and stood next to Li Ersheng.
Changsun Wuji glanced at Su Chen and said, "Your Majesty means, how long can you last without running for just one rest?"
Su Chen was stunned: "At this time, the machine does not need to rest, and it is not tiring. It keeps adding coal and keeps running!"
Li Er and the ministers beside him widened their eyes: "Keep running?
No need to rest?
As long as there is coal?”
"Yes! Of course, you have to add water after the water in the boiler is dried out."
Su Chen then explained: "This is a simple demonstration product, and many functions are not installed."
"A real train has its own coal carriage in the locomotive. There are workers next to the boiler who use shovels to continuously add coal to the furnace. When the coal in the carriage is burned out or the water is dried up, you only need to stop to fill it with coal and water and you can continue running.
Got it!"
Li Er and the ministers around him were very shocked:
"There is no need to rest. As long as there is coal to burn, you can keep running. Coal is plentiful in the Tang Dynasty!"
Wei Zheng sighed: "I can't wait to see what a real train looks like."
Su Chen smiled and said: "Don't worry, we will probably see you in half a year."
"Of course, the premise is that His Majesty agrees to build a railway!"
After forcibly closing the furnace mouth, the steam engine slowly stopped as the combustion slowed down.
Li Er quickly stepped forward, ready to take a closer look at how this thing ran.
It was a very magical thing for people of the Tang Dynasty to be able to run without being pushed or pulled by people or animals, or with the help of wind!
All the civil and military ministers also gathered around!
Su Chen hurriedly shouted: "Your Majesty, be careful, don't touch it randomly, be careful of burning it!"
But Su Chen seems to be shouting too late!
I only heard Cheng Yaojin yelling: "Brewed! It burned me to death!"
Cheng Yaojin jumped out of the crowd, waving his hands and shouting at Su Chen:
"If you didn't tell me if it was so hot, what would happen if it burned Your Majesty?"
Su Chen didn't say anything yet, only to hear Li Er say: "Do you think I'm as stupid as you?
That pipe with black smoke is obviously a chimney, how dare you touch it?"
Cheng Yaojin said quickly: "Yes! Yes! Your Majesty is wise, but this minister is stupid!"
Li Er raised his hand and pointed to a simple and honest young man among the craftsmen: "Come here!"
That young man was the one who just added more coal to the boiler. He pointed at himself and said, "Your Majesty, your name is me?"
"Yes, what's your name?"
"Your Majesty, my name is Wang Tie!"
"Oh, Wang Tie, come here and tell me what these institutions are for."
Su Chen stepped forward and said: "Your Majesty, it's me and you..."
Li Eryi glared: "You go away!"
"Your Majesty, you don't believe me?"
Li Er nodded: "You are very self-aware!"
Seeing Su Chen standing there with a confused look on his face, Li Er said again:
"What are you doing standing there stupidly? Haven't you seen all the ladies standing there in the cold wind for a long time?"
"Hurry back and prepare some hot soup for everyone!"
Su Chen walked home with an innocent look on his face: Li Er had something to say to the minister, but he didn't want to hear it himself.
"Boy, quickly call your doctor to show me!"
Cheng Yaojin caught up from behind and said, "If my hand gets burned and I can't turn the axe, I'll be doomed for the rest of my life!"
Su Chen glanced at Cheng Yaojin's slightly red palm: "It can't be damaged, at most it will peel off the skin!"
Cheng Yaojin shouted: "The skin is about to peel off, but it can't be broken?"
"Duke Protector, seeing that you are also the Duke, please quickly ask the doctor to apply some medicine to me!"
Su Chen was stunned: For the sake of both being the Duke of the country?
