Chapter 730: Propeller Becomes a New Object in Painting

"The prime minister should take charge of the overall situation and put the country's important affairs first. I always wanted Li Yi to come up with better things, but in the end..."

Yao Chong said this, shook his head, and started eating.

Seeing Song Jing now, he thought of himself in the past.

He also tried to do the work of a hundred craftsmen, but failed in the end.

To put it bluntly, whoever you think can be used by you must be used by you.

Zhang said yes, I am, and when it comes to Song Jing, it is still the same.

Your Majesty may hope that the prime minister will be tougher to handle things.

Of course, Li Yi is not made of clay. It's okay to fight in the air, but if you really come to him, Li Yi will also have a temper.

"Raising birds is always wrong." Song Jing heard the meaning of Yao Chong's words.

"It's winter, and the people can do less work. In addition to ice cutting and greenhouse planting, they only do the work arranged by Li's manor."

Wei Zhigu changed the subject and talked about the work of the people.

The work of spinning cotton, weaving cloth, and sorghum stalks arranged by Lijiazhuangzi has never stopped.

According to the amount of cotton and sorghum stalks, it is estimated that it will take until next year.

It means that Lijiazhuangzi has always been helping. You Song Jing should calm down and focus on other aspects.

"That's right." Song Jing was a little helpless. He saw that, except for Su Yan, the people he found today were all on Li Yi's side.

He thought that since he had met Li Yi and had a good talk, he had the responsibility to help Li Yi to be positive.

What's the use of raising pigeons and parrots? Write medical books when you should write medical books, and take out good things when you should take out good things.

Lu Huaishen stopped arguing. Anyway, he understood and supported Li Yi's pigeons.

As for the parrot, didn't the parrot say that Hu Feng, the hunter who once helped catch the Khitans, caught it?

He gave it to Li Yi, so how could Li Yi refuse it?

"I don't know if it snowed in Tubo. This year, our Tang Dynasty did not agree to Tubo's proposal for peace. Tubo will probably take some action."

Su Yan changed the topic. He, as a prime minister, was like Lu Huaishen, doing detailed work.

"More than 20,000 Tang civilians were exchanged, and there were still hundreds of Tibetan captives who were not sent back because they could not gather Tang civilians."

Bi Gou was the prime minister, and he was not so obsessed with money.

He praised the battle of Songzhou, killing many enemies and taking many captives.

The civilians looted by Tubo came back, of course, some did not come back, and Tubo was also divided into tribes.

Some tribes had no one captured by the Tang Dynasty as a captive, so they would not exchange the looted Tang civilians.

In addition, other forces were huge, and many captives were captured, so they exchanged things with tribes with Tang civilians.

The captives who were not exchanged back showed that their forces could not get Tang civilians.

Both prime ministers talked about Tubo, so Song Jing had to give them face and talked about it in the same way.

"I guess Tubo will fight again in the spring, at least to grab some food."

This is what Song Jing considered. Tubo lacked farmers, and a group of people fighting did not know how to farm.

The food cultivated by the Tubo people who could farm was just enough to eat. Tubo did not take advantage of the fact that the Tang Dynasty had not yet assembled its troops to fight once, otherwise there would be no chance.

"We need to talk to Li Yi about this matter." Lu Huaishen thought it made sense, and thought of Li Yi, and told Li Yi.

Song Jing: "..."

He felt that something seemed to be wrong. He wanted Li Yi to do something, but a group of people opposed it.

If he said something, he would tell Li Yi.

Who is the prime minister? Do I have to report to Li Yi?

……

Li Yi, who became the center of the topic, did not have much contact with the great rose-breasted parrot.

He had something to do, and the workshop made the propeller he designed.

The diameter of the propeller is two feet, which is considered large if it is powered by gasoline or diesel.

But there is no such equipment in the manor, so it can only be powered by human power.

Connect the transmission equipment, put it behind the boat, and pedal it, and the propeller will rotate.

The bearing is not good, so just use it.

Wooden ships can turn, and iron ones can turn too.

The disadvantage is that steering still depends on the rudder, not adjusting the propeller.

The transmission system of the propeller is fixed, and the rudder used should be the front rudder.

Or put the propeller in the middle of the bottom of the boat, and the rudder is at the back.

Either the rudder is in the middle, or the propeller cannot turn back and forth.

"There is water in the Ba River. Before it freezes, make a wooden boat, install the paddle, and try it out. We can adjust it."

Li Yi recognized the craftsmanship of the craftsmen, and the rest is practice.

The craftsmen found and made traditional equipment, and the boat on the carpenter's side was also built.

The wooden boat can carry eight people, with a load of fifteen stones, and four people are responsible for pedaling together.

Now it just needs to be assembled. If the speed is faster than the ship, then by next year, the carrying capacity of the water network will be greatly improved.

Coming out of the workshop, Li Yi sighed: "We need rubber to make a sealing system, so that we can make a diesel engine, a single-cylinder one will do, very small, and gasoline is also OK."

Li Yi thought of a car, two wheels are hand-pushed, and you can add a wheel, pedal, like a bicycle.

But for a while, someone put a very small diesel and gasoline cylinder on the car.

So it became a three-wheeled power-assisted car, and the diesel and gasoline engines on it were very small, and smoked when they turned.

Don't underestimate that kind of car, it's very fast.

If there is rubber, it can be made.

The chain of the bicycle is a bit difficult. Although the chain structure is simple, the metal requirements are not low.

"Why don't we ask them to cast some chains first to see if they are useful? Bicycles don't need tires. Just ride them directly. It's bumpy. I believe that cement roads are still fine."

Li Yi didn't want to copy books today. He muttered and ran back to the study to design a bicycle, a real bicycle.

The parts were simplified as much as possible. Brakes were not needed. The shaft was dealt with. There were two wheels and front and rear gears. The front one was bigger and the rear one was smaller. The diameter and teeth also needed to be designed.

Otherwise, the front and rear could not be stuck. There was a gap between the chains.

There was no bearing at the handlebar position. A sleeve was used, so it was flexible when riding.

Li Yi drew until the evening. He finished the design and walked out with a stack of drawings.

"Ah! Old Bi, are you not busy in the government hall?"

When Li Yi left the yard, he saw Bi Gou standing at the door, blown by the cold wind.

"Not as busy as you, UU Reading www.uukanshｕ.net I just went in and you didn't notice, drawing, calculating, I came out because I didn't want to disturb you."

Bi Gou looked at Li Yi and said, then his eyes moved to the pile of papers.

Li Yi thought about it, but he didn't remember.

He smiled: "I designed a bicycle with an iron chain. It may not achieve the expected effect when operated, but the technology can only be improved if it is made first."

"Okay, the craftsmen of the Tang Dynasty should have your kind of belief, and I support you. That... after it is made, is it a luxury? The kind that sells for a high price?"

Bi Gou changed the subject smoothly. Money, he is the prime minister, but he is still the minister of the Ministry of Revenue.

"Yes, only those who have bought kerosene lamps and thermos bottles before will be eligible to buy them."

Li Yi is not sure, but the old man is waiting outside, so he has to make him happy.
