"Zai is quite in charge of the overall situation and puts the country's priorities first. The old man always wanted Li Yi to come up with something better, but the result was ......"

Yao Chong said a word, shook his head after speaking, and began to eat.

Seeing the current Song Jing, he thought about his former self.

I also did a lot of work, and finally failed.

To put it bluntly, whoever you think can be used for yourself, that person must be used for yourself.

Zhang said yes, he is, changed to Song Jing, or.

Your Majesty may want the Prime Minister to be tougher so that things can be handled.

However, Li Yi is not muddy, it is okay to fight in the air, if you really find the door, Li Yi also has a temper.

"It's always wrong to keep birds." Song Jing heard the meaning of Yao Chong's words.

"In winter, the people can do less work, except for digging ice and planting greenhouses, only the work arranged by Li Zhuangzi is doing."

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

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

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

It shows that the Li family Zhuangzi is always helping, and you Song Jing stopped and focused on other aspects.

"That's exactly how it should be." Song Jing was a little helpless, he could see that the people he was looking for today, except for Su Ying, everyone else was towards Li Yi.

He thinks that since he has met Li Yi and talked well, he has the responsibility to help Li Yi be positive.

What is the use of keeping pigeons and parrots? When you should write a medical book, you will write a medical book, and if you should take out a good thing, you will take out a good thing.

Lu Huai was cautious, anyway, he understood and supported Li Yi to get carrier pigeons.

As for the parrot, didn't the parrot say that Hu Feng once helped catch the Khitans and got caught by the hunters.

He gave it to Li Yi, can Li Yi still want it?

"I don't know if it has snowed in Tibet, but this year, my Datang did not agree to Tubo's proposal for peace, and Tubo will take action in the future."

Su Ying changed the topic, he, the prime minister, was the same as Lu Huaishen, doing detailed work.

"More than 20,000 people of the Tang Dynasty were exchanged, and hundreds of Tibetan prisoners were not sent back because they couldn't get together the people of the Tang Dynasty."

Bi Gou became the prime minister, and he was a little less always thinking about money.

He affirmed the first battle of Songzhou, killing many enemies and taking many prisoners.

The people who were plundered by Tubo came back, and of course they didn't come back, and Tubo was also divided into tribes.

Some tribes have no one captured by the Tang Dynasty as prisoners, so they will not exchange the people of the Tang Dynasty for the plundered Datang people.

In addition, there are other forces that are huge, and there are many captives who have been captured, and they exchange things with tribes with the people of the Tang Dynasty.

The captives who were not exchanged back showed that their forces could not get the people of the Tang Dynasty.

The two prime ministers both talked about Tibet, and Song Jing had to give a face, and they also talked about it.

"Tubo is estimated to fight in the spring, at least grab some grain."

This is something that Song Jing considers, there are fewer people who farm in Tibet, and a group of people who fight in the war will not be able to farm.

The grain cultivated by the Tubo people who can cultivate will be enough to eat, and the Tubo will not take advantage of the fact that the Tang Dynasty has not yet assembled the troops to fight once, and there will be no chance to wait any longer.

"I want to talk to Li Yi about this matter." Lu Huaishen felt that it made sense, remembered Li Yi, and told Li Yi.

Song Jing: "......"

He felt that something seemed wrong, and he wanted Li Yi to do something, but a group of people objected.

If he said something, he had to tell Li Yi.

Who exactly is the prime minister? Have to report to Li Yi?

……

Li Yi, who became the center of the conversation, did not have much contact with the big scarlet-breasted parrot for long.

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

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

However, there is no such equipment in Zhuangzi, and it can only be driven by artificiality.

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

The bearings are not good, so they can be improvised.

Ships of wood can turn, and iron ships are the same.

The disadvantage is that the steering also relies on the rudder, not the adjustment of the propeller.

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

Or put the propeller in the middle of the underside of the boat and the rudder in the back.

Either the rudder is in the middle, and the propeller can't turn back and forth anyway.

"There is water in the water, take advantage of the fact that it is not frozen, make a wooden boat, install the oars, try whether it works well, we can adjust it full."

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

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

You can take a wooden boat for eight people, with a load capacity of fifteen stones, and four people are responsible for stepping on it together.

Now it is enough to assemble it, and if it is faster than a ship, then next year, the carrying capacity of the water network will be greatly improved.

Coming out of the workshop, Li Yi sighed: "You need rubber to make a sealing system, so you can make a diesel engine, a single-cylinder one, a very small one, and a gasoline one." ”

Li Yi thought of a kind of car, two wheels pushed by hand is with a car, you can add a wheel, with pedals, bicycle kind.

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

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

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

If there is rubber, it can be made.

The chain of the bicycle is a little hard, don't look at the simple structure of the chain, the requirements for metal are not low.

"Why don't you let them cast some chains first, see if it's easy to use, the bicycle doesn't need tires, ride directly, bumpy on bumps, I believe the cement road is still fine."

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

The parts are simplified as much as possible, the brakes are not needed, the shaft is dealt with, there are two wheels and front and rear gears, the front is larger, the back is smaller, and the diameter and teeth should also be designed.

Otherwise, it can't be stuck before and after, and the chain has a spacing.

The position of the handlebar is not on the bearing, with a sleeve, flexible when riding.

Li Yi painted, until the evening, he designed it, and he took a stack of drawings and walked out.

"Yikes! Lao Bi, are you not busy in the political hall? ”

When Li Yi came out of the yard, he saw him standing at the door and being blown by the cold wind.

"You're not busy, you didn't notice when I went in just now, painting, counting, I'm afraid of disturbing you and coming out."

Bi Gou looked at Li Yi and said, and then his eyes fell on the stack of papers.

Li Yi thought about it and was not impressed.

He smiled: "I designed a bicycle with iron chains, and the operation may not be able to achieve the expected effect, but the technology can only be improved if it is made first." ”

"Okay, Datang craftsmen should have your kind of faith, and the old man supports you. That one...... After it is made, it is a luxury? The kind that sells for a lot of money? ”

Bi Goushun took the topic crookedly, Qian, he is the prime minister, but he is still in charge of the household department.

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

Li Yi wasn't sure, but the old man was waiting outside, so he always had to make the other party happy.
