Li Chengqian finally discovered the mystery of this thing.
There is a hat-like thing on the chimney mouth.
All smoke enters the hat first and then is discharged outside.
Li Chengqian couldn't help but get closer: "Boss! What is this?"
The stall owner looked up and smiled.
"Isn't this just a chimney?"
"It's not the chimney, it's the one above the chimney." .??.
Li Chengqian pointed to the little hat and said, "Where did you get this thing?"
"Oh, this."
"This is a gadget that the carpenter next door to my house made when he was free."
The stall owner smiled and said: "It is said that it is based on the wind mill of our Datang Dynasty."
Windmill…
Li Chengqian nodded and said, "Your neighbor is very talented."
"By the way, can you take this thing off and let me see it?"
"There's nothing not to see here."
The stall owner took off the little hat-like thing and handed it to Li Chengqian.
In fact, the principle of this little hat is very simple, just like the chimney mouth in rural areas in later generations.
There is something like a fan inside, connected to a small mechanism.
Just shake the wheel underneath.
The smoke will be continuously drawn out.
At the same time, air will be continuously drawn in from the inside of the stove, allowing the firewood to burn more fully.
When Li Chengqian saw this thing, another thought came to his mind.
yes.
You can definitely install an exhaust system on the iron warship.
As long as the cabin can be kept as dry as possible, won't the coal not become damp?
Li Chengqian has a do-it-yourself temperament.
He immediately said to the stall owner: "Give me all the candied peanuts on your stall and don't want the rest."
"ah?"
The stall owner was surprised: "No? Then...I can't find the money."
"Keep the change, please." Li Chengqian played with the wind and said without raising his head: "I'll reward you."
The stall owners were all confused.
He has never seen such a generous guest.
After Li Chengqian left, he was in a dazed state.
He couldn't help but murmured: "This man is really weird..."
"Strange?"
"I said, brother, you haven't figured out who he is yet?"
At this time, a person running a stall next to him suddenly interrupted and said.
"who is it?"
The stall owner looked confused.
"The current prince Li Chengqian!"
In addition, the owner of that stall has been setting up his stall in this place for many years.
And Li Chengqian is not the kind of person who never leaves home and never goes out of his way. He always wanders around the city when he has nothing to do.
So these old traders basically all know him.
They recognized Li Chengqian just as he walked over.
The peanut vendor was obviously new here, and he was frightened to death when he heard these words.
"Tai...Prince?"
"You, you said the one just now was the prince?"
In his opinion, the prince is an extremely noble person.
Not to mention ordinary people, even officials with lower official positions may not have seen it.
But she happened to meet him, and chatted and laughed with him face to face.
For a moment, the peanut vendor didn't know whether to be happy or scared.
"Our prince is different from those in folklore."
"He can't help but give money when he eats, and if he does a good job, he will give him a reward every time."
"So you don't have to be afraid, he won't come to blame you."
The vendor smiled and reassured him.
Hear this.
The peanut vendor was relieved.
But at the same time, he was afraid again.
It is useless to say anything in front of this person.
And the other side.
Li Chengqian took a carriage and ran all the way back to the East Palace.
After returning to the East Palace.
He ran straight to the study room and spent half an hour drawing a complete exhaust system.
Although contemporary materials are limited and the technical level is limited.
But it’s always okay to come up with a simplified version.
Wait until the drawing is finished.
Li Chengqian asked Xiao Chuzi to call all the carpenters in the East Palace.
Most of the carpenters in the East Palace stayed with Li Chengqian when he was in Prince Qin's Mansion.
So, these people also know it.
Li Chengqian called them over, and he must have come up with another good idea.
And Li Chengqian didn't talk nonsense.
He directly handed the drawings to several people in the venue: "Did you see it?"
"Just follow my drawings and make a rough model."
"The total length of this thing is estimated to be about three meters."
“But remember, even though it’s small, you can’t be careless.”
"You all have to keep this saying in mind that even though a sparrow is small, it has all its internal organs. Do you understand?"
Hearing this, everyone nodded in agreement.
Next.
The head carpenter took the drawings and went to find materials.
Li Chengqian stayed in the study and reimagined the internal structure of the iron warship.
After all, it was his first time to study such a big thing.
Therefore, mistakes are inevitable.
For example, the exhaust is one of the problems of iron-clad warships.
However, it is easy to install an exhaust. The final step is to arrange the exhaust at the appropriate location.
And because of the first experience.
This is not a difficult problem for Li Chengqian.
The main thing is to see how the shipyard and ordnance camp implement it in the end.
And it was just when Li Chengqian was writing furiously.
Su Qing Ling walked in slowly.
Seeing how lively Li Chengqian was working, she didn't speak, but just stood aside silently.
Li Chengqian was sweating, so he wiped his sweat with a handkerchief.
Seeing that he was thirsty, he handed him a glass of water.
Li Chengqian is a true technical geek.
As long as he is fully committed, he will not hide even if an earthquake comes.
It was only when he was halfway through the drawing that he discovered that his wife was standing next to him.
Li Chengqian was a little stunned, but he quickly came to his senses.
"What's wrong?"
Li Chengqian asked while drinking water: "Do you have anything to do with me?"
"It's not a big deal."
"I'm just asking you if you have time in three days."
Su Qingling said unhurriedly: "My father is here to invite you, saying that he wants to invite you to our house for a party."
"Your dad? Invite me?"
Li Chengqian was a little confused.
Ever since Lu Wanjie married him.
In order to avoid suspicion, Su Dan would almost never take the initiative to invite him to the house as a guest.
What happened today?
Su Qingling lowered her head and said with a red face: "I have a younger brother..."
After hearing this, Li Chengqian finally understood.
It turns out that Su Dan himself has a happy event.
But if you think about it carefully, it's not easy for Su Dan.
Earlier, he only had one daughter, Su Qingling, but now he is nearly forty and finally has a son.
And if Li Chengqian remembered correctly, his youngest son seemed to be able to become a big shot in the future.
Although Su Gui, Su Quan's son, was not well-known in his early years.
But in his later years, he dominated the Tang Dynasty court.
When Empress Wei was plotting to usurp the throne, she protected the royal family and fully assisted Liuwei Dihuang Pill Li Dan in ascending to the throne, stabilizing the chaos for the Tang Dynasty.
"Since it's my father-in-law's invitation."
Li Chengqian said with a smile: "Even if I don't have time, I will make time to go there."
