"That's how it is." Bi Gou found Li Yi and repeated Song Jing's words.

"Of course, the gears cast by cast iron can be used. They are good at wear resistance, but they can't bear it when they are high-strength. The farm is steel."

Li Yixian admitted that the gears of cast iron are fine and the quality is not very good unless it is replaced with ductile iron.

"In crankshaft applications, cast iron is not good, and human pedaling is OK. With the cast iron half-shaft, the overall torque is too high, which is not very good."

Li Yi introduced the structural characteristics of propeller boats and the material properties of pig iron.

It is concluded that pig iron can be used, but it is easy to break, and it can be pedaled with all humans and can last for a period of time.

"Since that's the case, why do you need to rent it?" Bi Tao couldn't understand and asked.

"When will I say renting? I'll just try it out if it's easy to use. The new drawings that can be changed have been handed over to the workshop.

After the workshop is made, the force and speed can be adjusted. For example, when the water flows backwards too fast, you need to adjust the gears, otherwise you will not be able to withstand it."

The principle mentioned by Li Yi is the same as the speed change of bicycles when going uphill. You can no longer use large wheels in the front and small wheels in the back.

"Not renting?" Bi Gou found that everyone was worried in vain.

"That thing is expensive. Who pulled the boat up? If the thing is dismantled, where can I find it? The new propeller will be used for the army in the future, and the farm will also use it."

Li Yi told the truth, things are too precious and not suitable for renting, so they are afraid of losing them.

Bi Gou felt relieved: "It can be installed on a large ship, and more people can step on it."

"No, the material cannot withstand that force, so it is feasible to disperse the propeller assembly, but it has weight in itself.

Later, I made the steam engine, drove it with the steam engine, and loaded coal on the boat to boil water.

Carry a seawater filter device and sail on the ocean for a long time, and go to a farther place to see.”

Li Yi has a complete set of skills and is waiting for the ship. In recent years, the navy has been abandoned.

Even if it is not abandoned, the ocean-going ship should be larger and carry sails at the same time.

Then build a steam engine as a flagship.

You can abandon ships on the road and exchange money for the lives of seafarers.

At that time, these seamen who come back alive to America will be valuable assets, allowing them to bring more people to familiarize themselves with the route.

Mainly, where the ocean currents are more detailed, which island has fresh water.

If you really don’t have fresh water, try it with drilling equipment.

Li Yi told Bi Gou that he had said to Li Longji and Li Chengqi before, and the two expressed their full support.

"So, aren't you focusing on Tubo?" Bi Gou came to a conclusion from Li Yi's words.

"The incident that happened to the Tubo for several years was settled directly, and there were also Turks.

The Turks were not as good as Tubo, and they did not develop well within the Turks, and they fought everywhere.

What foundation does it have until now? With a sense of martial arts, you need to have no technology and reserves.

Tubo is a completely slave social structure, with breeding and planting technology, handicraft processing technology, and weapons can be produced by themselves."

Li Yi looked down on the Turks and did not take the Turks seriously. Instead, Tubo needs to be fought for two years.

Now is a period of accumulating national strength, endure it and then fight to Europe.

"As long as the key technologies are not spread, Lao Bi, we can fight all over the world, and no one is our opponent."

Li Yi is confident that in order to suppress Tianzhu and Dashi within the next ten years, his own side will suffer very little losses.

Bi Gou heard the technology and pondered for a moment: "Xiao Yi, tell me the truth. If you don't count the things you exchanged for your life, how powerful is it now?"

"A generation of manual lathes have come out, converter steelmaking has come out, chemistry and physics are teaching students.

Don’t think they will still learn from me when they go out to be officials. I can take the exam, but if I fail, I will remove him from my official position.

Biology is teaching nurses, and they will gradually improve.

The production of glass and the progressive finishing can provide basic optical instruments.

Sextants and theodolites can appear at any time. Several more theodolites are produced this fall to measure the terrain, which is easier to use than the current method.”

Li Yi didn't directly answer how powerful he was, and he couldn't say how many years he was ahead.

Anyway, the foundation has been laid, and the real thing is not what he has produced under his guidance, but what the students have learned.

Especially for the farmer and craftsman, the term craftsman sounds like a low-level existence.

In fact, Zhuangzi's craftsmen learned a lot, and any craftsman took it out is a treasure.

It is necessary to have a theoretical foundation and craftsmanship. It is not allowed to leave the farm alone on weekdays to avoid being arrested.

Bi Gou didn't understand it. Anyway, he felt it was extraordinary, and his ability to understand technology was limited.

"It's warm, so bring more hot sauce for me. It's hot. If you want to get the heat, you have to eat the water surface." Bi Gou instantly changed the topic.

"Will you not get angry when you eat spicy sauce?" Li Yi wanted to say it from a medical perspective.

"Hurry up, when you kill the cattle again, give me beef sauce, don't send it to the government affairs hall, unless you prepare more, they will steal my stuff."

Bi Gou didn't want to listen to the doctor, so he wanted to eat spicy sauce.

"I'll have it now. I'll send it to you home, or do you take it with me?" Zhuangzi was so new that he was a dead cow yesterday.

When I was plowing the land, I suddenly wanted to take over the owner. Fortunately, there was a plow on my body. The owner ran away and found someone to kill the cow and sent it to the Li family village.

Li Yi has tested it, no problem, can eat it.

As for why the cow wants to be the master, it is not something he needs to consider.

Maybe the owner is too harsh on the cow, or maybe the cow is depressed. No matter which one, the cow must die.

He had an old couple at that time, and they bought cattle to keep them for work.

When it's time to sell, the cow will be too powerful.

There were also separate people who wanted to sell cattle, but the price was not negotiated and took the cattle home, but they were overwhelmed by the cattle.

Maybe I feel that my owner wants to sell him and he will be killed.

Li Yi didn't know what the situation was, and he was not awesome.

The cattle on the farm were all very good. They said that when working, they had to plow the cows. The cows stood and waited, and they put on the ground and started to plow the land.

After plowing the land, you have to bathe the cows, and they also stand and enjoy and then eat.

I have never gotten angry and get along well with others.

Bi Gou heard about the past, but did not express his opinion. He left with beef and spicy sauce. He was preparing to go home to eat noodles at night, asking for wide noodles and water.

Before night time, the news spread about the new ship that could fly to the water.

At the end, the Lijiazhuang ship encountered a shore barrier, flew from the land for a while, and returned to the water.

This is relatively restrained, otherwise it can be heard from flying into the sky, flying higher and higher, and flying towards the sun.

In the evening, Li Longji and his family of three arrived and brought a newly killed cow.

He knew that Li Yi was unwilling to kill the livestock who worked. He was soft-hearted and timid, so he arranged for someone to kill him, but he didn't do anything by himself.

In fact, this cow is not a cow that works, but is specially raised for royal food.

It is more fatter than the cows used to work, and it is probably going to be a problem.

Generally, when raising cattle, you have to teach it from childhood, otherwise the cattle will not understand it.

It is best to have big cows working, small cows grow up in the working environment, and then let them cultivate the land, so that they can cooperate better.
