Ah Chao was in the iron-smelting base, and Li Zhao handed him the drawings and methods for manufacturing the main components such as the cylinder and control valve of the steam engine.

Ah Chao glanced at it, didn't say much, and took it.

Li Zhao hadn't been to the iron-smelting base for a long time, and this trip was timely, so he went inside to inspect it.

Since the establishment of the base, he has given Ah Chao a lot of cheats, and he wants to see if the craftsmen of the base are well understood.

Walking inside, the base that appeared in front of me was simply dazzling.

Just returned from the imperial court's weapons manufacturing office, this is compared to the weapons manufacturing office, the weapons manufacturing department is simply weak.

This is what an iron-smelting base should look like.

Large furnaces, mountains of iron ore, dozens of blowers, machine tools and other appliances not far away, and other elemental ores can be seen next to it, although the number is less, but it is very surprising to Li Zhao.

He once told Ah Chao about the shape and color of various mines, and asked Ah Chao to send someone to find it, and it seems that Ah Chao is very concerned.

Looking at the furnace again, there was something similar to coal, but it was very dark, Li Zhao's eyes were even brighter, this was coke, when he handed over the secret book of smelting steel to Ah Chao, he asked Ah Chao to try to smelt coke, and it seems that he succeeded.

Of course, since steel can be smelted, it must have been successful very early.

Coke is obtained by dry distillation of coal at a high temperature of about 1000°C, and it is difficult to reach a high temperature of 1,000 degrees Celsius according to the current calcination technology of Daqin, but after Li Zhao gave the manufacturing drawings of the blower, the situation was different.

It is difficult for ordinary charcoal fire to reach 1,000 degrees, but under the blowing of the wind, it is much easier.

The temperature produced by coke combustion is very high, once the coke is distilled, it is not difficult to continue to produce it, and with coke, it is much easier to turn iron ore into molten iron.

This is something that Daqin's current technology can't do.

Looking at the side, there are finished steel products, which are piling up, and at this moment, the major forging places are in full swing, and it seems that mass production is about to be made.

On the other hand, the wires were also manufactured, and although they were larger than the ordinary wires of the previous life, they did not hinder their use, and the craftsmen mastered the technology, and a layer of rubber was wrapped on the surface of the wires.

"Uh-huh!"

Li Zhao nodded in satisfaction.

With steel and wires, the hydropower plant will soon be ready for construction.

"You have to produce these parts as quickly as possible, you have to ensure hardness and toughness, the dimensions must be accurate, and the errors must be minimal."

There must be emergency contact between the cylinder and the piston of the steam engine to prevent steam leakage, so it must be particularly accurate, but Li Zhao is not worried, when making firearms, he told Ah Chao the manufacturing method and fine scale of the ruler, with the ruler, the error will not be too large.

Ah Chao nodded.

Soon, Li Zhao was gone.

In Chang'an Township, an uninvited guest came, this person was old, his face was haggard, but there was deep concern in his eyes, as if there was a dead knot that could not be dissolved lingering all over his body.

Regardless of the fatigue of the past few days, he dragged his not very straight body and walked towards the farmland of Chun Yuyue.

This person is the smart old man.

In the field, Chun Yuyue is still hoeing grass, his body is still so rickety, and the time he has been a farmer has made him tired and his temperament has sunk a lot.

"Chun Yu old man, tell me, is it intentional? Isn't it? Before the agile old man arrived, his voice came.

"Are you trying to kill me? Just for such a little preconception, are you embarrassed to damage the relationship between the two of us for many years? ”

"You old immortal, I'm not done with you."

The old man began to scold and scold, and came directly to Chun Yuyue.

Chun Yuyue raised his head, saw the angry figure, smiled calmly, did not continue to hoe, but took a few steps, picked up the hoe from the side, staggered back to the original place, and threw it aside.

"Old immortal, why don't you speak? Is it that being a farmer makes you stupid? Seeing that Chun Yuyue was silent, he didn't even bother to look at him twice, and he was smart and old-fashioned.

Finally, Chun Yuyue smiled a little and spoke: "The person who is about to enter the soil is still so impatient, come and come, help hoe the grass and dissipate his anger." ”

I simply picked up the hoe and threw it over.

The agile old man was very angry and kicked the hoe aside.

", tell me what you mean?"
