"That's what happened." Bi Goo found Li Yi and repeated Song Jing's words to him.
"Of course, the gears made of pig iron can be used. They are not bad in terms of abrasion, but they can't withstand high strength. Zhuangzi uses steel."
Li Yi admitted that there was no problem with the cast iron gears, but the quality was not very good unless they were changed to ductile iron.
"In terms of crankshafts, the cast iron is not good. It's still okay to use human power. In addition to the cast iron half-shafts, the torsion force on the whole is too high. It's not very good. "
Li Yi introduced the structural characteristics of the propeller ship and the material properties of the pig iron.
The conclusion was that the pig iron could be used, but it was easy to break. It could be used for a period of time.
"If that's the case, why are you renting it out?" Bi Goo could not figure it out and asked.
"When are you talking about renting it out? I'm just testing whether it's good or not. The blueprint for the new gear change has been given to the workshop.
After the workshop is produced, the power and speed can be adjusted. For example, when the current is too fast, the gears need to be adjusted. Otherwise, it will not be able to withstand it. "
Li Yi said the principle was the same as the speed change of a bicycle when going up a hill. They could no longer use the big front wheel and the small rear wheel.
"Not renting it out?" Bi Goo found that everyone was worried for nothing.
"That thing is expensive. Who will pull the ship up and dismantle it? Where can I find it? The new propeller will be used by the military in the future. Zhuangzi will also use it. "
Li Yi was telling the truth. The thing was too precious and not suitable for renting. He was afraid of losing it.
Bi Goo was relieved: "But if it's installed on a big ship, more people will step on it."
"No, the material can't withstand the force. It's possible to build a separate propeller, but it has its own weight.
In the future, I will make a steam engine and use it to drive the ship. The ship will be loaded with coal to boil water.
It will be equipped with seawater filtration equipment. After sailing for a long time, we will go further to see. "
Li Yi had a full set of technology and was waiting for a ship. In recent years, the navy had been abandoned.
Even if it was not abandoned, it was not good. The ship must be bigger and have sails.
Then, he would build a steam engine ship as the flagship.
Ships could be abandoned on the way and the lives of sailors could be exchanged for money.
When the time came, the sailors who went to America and came back alive would be a valuable asset. Let them bring more people to familiarize themselves with the sea route.
The main thing was now that the ocean currents were more detailed, and which islands had fresh water.
If there was really no fresh water on the island, they would bring drilling equipment to try.
Li Yi shared his idea with Bi Goo. He had shared it with Li Longji and Li Chengqi before, and both of them had expressed their full support.
"So, you're not thinking about Tubo?" Bi Goo concluded from Li Yi's words.
"We've been fighting Tubo for a few years, so we'll settle it once we make a move.
The Turks couldn't compare to Tubo. They didn't develop their internal affairs well and instead fought everywhere.
After fighting for so long, what kind of foundation did they have? Relying on their bravery, they had neither the skills nor the reserves.
Tubo was a completely slave society. They had the technology of breeding, planting, handicrafts, and they could produce their own weapons. "
Li Yi looked down on the Turks and didn't take them seriously. On the other hand, Tubo needed to be fought for two years.
Now was the time for the country to accumulate strength. They had to bear with it for a while and then fight their way to Europe.
"As long as the key technology isn't leaked out, Old Bi, we can conquer the entire world. No one is our match."
Li Yi was confident that in the next ten years, they could suppress India and Arabia, and their losses would be minimal.
Bi Goo heard about technology and pondered for a moment. "Xiao Yi, tell me the truth. If you don't use your lifespan to exchange for Zhuangzi, how powerful is it now?"
"The first generation of handmade lathes and converters have been produced. Chemistry and physics are being taught to the students.
Don't think that they will still learn when they become officials. I will take exams, and if they don't pass, I will remove them from their positions.
Biology is being taught to the nurses, and they will gradually perfect it.
The production of glass and the gradual improvement in precision processing can provide the basic optical instruments.
The sextant and theodolite can be produced at any time. A few more theodolites will be produced this autumn, and they can be used to survey the terrain. It is more useful than the current method. "
Li Yi didn't directly answer how powerful it was, and he couldn't say how many years ahead it was.
Anyway, he had been building the foundations. What was truly powerful was not what was produced under his guidance, but what the students learned.
This was especially so for the farmers and craftsmen. The term craftsmen sounded like low-level existences.
In fact, the craftsmen in Zhuangzi had learned many things, and any craftsmen could bring out treasures.
They had the theoretical foundation and craftsmanship. They were not allowed to leave Zhuangzi alone to avoid being caught.
Bi Goo didn't understand, but he felt that it was unusual. His understanding of technology was limited.
"The weather is warm. Bring more chili sauce for me. It's too hot. I have to eat water." Bi Goo immediately changed the topic.
"Won't eating chili sauce cause excessive heat?" Li Yi wanted to explain from a medical point of view.
"Hurry up. When you slaughter the cow, send beef mince to me. Don't send it to the Political Affairs Hall. Unless you prepare more, they will rob my things."
Bi Goo didn't want to listen to the doctor. He just wanted to eat chili sauce.
"I have some now. Should I send it to your home, or do you want to bring it with you?" Zhuangzi had a new dead cow yesterday.
When the cow was plowing, it suddenly hit its owner. Fortunately, the owner ran away and found someone to kill the cow and send it to the Li Family Zhuangzi.
Li Yi had tested it. There was no problem. It was edible.
As for why the cow hit its owner, it wasn't something he needed to consider.
Maybe the owner was too harsh on the cow, or maybe the cow was depressed. No matter what, the cow had to die.
At that time, he and his wife bought a cow and raised it to work.
When it was time to sell it, the cow hit its owner.
There was also a man who wanted to sell the cow. He didn't agree on the price and brought the cow home. As a result, he was hit by the cow.
Maybe the cow felt that its owner was going to sell it and that it would be killed.
Li Yi didn't know what was going on. He was not a cow.
Zhuangzi's cows were all good. When it was time to work, it was necessary to put a plow on the cow. The cow stood and waited for the plow to start plowing.
After plowing, it was necessary to bathe the cow. The cow also stood and enjoyed the bath. Then, it ate.
It never lost its temper and got along well with people.
Bi Goo heard what happened, but he didn't say anything. He took the beef and chili sauce and left. He was going to eat noodles at home in the evening. He wanted noodles that had been soaked in water.
Before the evening, the news about the Li Family Zhuangzi's new boat that could fly close to the water spread.
In the end, it was said that the Li Family Zhuangzi's boat was blocked by the shore. It flew from the land for a while and returned to the water.
This was relatively restrained. Otherwise, it would have flown into the sky and flew higher and higher towards the sun.
In the evening, Li Longji's family of three came and brought a freshly slaughtered cow.
He knew that Li Yi didn't want to kill working animals. He was soft-hearted and timid. Therefore, he arranged for someone to kill it. He didn't do it himself.
In fact, this cow wasn't a working cow. It was specially raised for the royal family to eat.
It was fatter than working cows. It would probably cause problems if it was used to work.
Generally, working cows had to be taught from a young age. Otherwise, the cow wouldn't understand.
It was best if there was a big cow working and a small cow watching. It would be better if it grew up in a working environment and then let it plow the land.
"Brother Yi, the boat has started sailing at Hukou Waterfall. It's very successful." Li Longji came specially to report the good news.
