With the first piece of iron ore mined in Green Field, the construction of the steel plant was naturally put on the agenda.

It is not an easy task to smelt iron ore into usable steel.

In another cosmic plane, humans began to use natural metals in the Stone Age.

However, it was not until about 5000 BC that copper was learned, and it is said that the ancient Romans were already using iron nails.

However, until the twentieth century, before the great progress of metallurgical science, the only way to make a good piece of steel was basically to rely on luck.

In the case of Brattis, for example, the dwarves are often thought to hold the mysteries of blacksmithing, but even those who are known as masters have limited production capacity.

Just like the Japanese swordsmiths of the past, there may be only a few pieces of work throughout the year.

It's not that they don't want to build more, after all, no one can't get along with money, but the reason is that there are too many uncontrollable factors in the entire forging process.

Experience does work, but it doesn't always work.

The good news is that Li Yu is here, and there will be no need to wait for hundreds of years for mass production of qualified steel.

An engineer named Besemer has long since written down the standard answer.

- By fully contacting the molten iron, the oxygen and the carbon in it react chemically to produce carbon dioxide, so that all the carbon in the iron is removed, and then the carbon element is mixed in according to the proportion.

The advantage of this is that the carbon content of the iron ore itself can be completely ignored, and no matter what quality of ore can be smelted into steel.

Bessemer later opened his own steel mill and made a lot of money.

Li Yu remembered that during the period of large-scale steelmaking, the local method of steelmaking vigorously promoted by the people in various places was also based on the same principle.

It can be seen that if there are no strict requirements for the quality of steel, steelmaking does not require any high-precision equipment and equipment, which can be done with the current productivity level of Brattis.

In this way, Green Field should soon be able to achieve freedom in armor and weapons, and in the future, it can even be sold domestically and re-exported.

Of course, that's all for later. At present, the most important thing is to build the blast furnace first, and Li Yu planned to hand over this errand to Ge Lipeng at the beginning.

Because Ge Lipeng, as a handicraft expert, is no stranger to the Bessemer steelmaking method, but in addition to learning the language, Ge Lipeng was also busy imitating the Iowa rifling machine, which is used to cut rifling in the barrel of a gun.

Previously, he had made a smoothbore gun according to Li Yu's request and helped Miss Rabbit win the championship of the martial arts competition.

But Ge Lipeng was not satisfied, especially after seeing the terrifying flying ability of those Wing Clansmen, he didn't need to be reminded by Li Yu, he had already begun to continue to improve those flintlock pistols.

What he is doing now is to engrave rifling in the barrel to further improve the muzzle kinetic energy and shooting accuracy.

However, Ge Lipeng recommended another person to Li Yu.

"He Chaoyang?" Li Yu thought for a while, shook his head and said, "He can't do it, he was injured too deeply by civil engineering, I promised him before I was reincarnated that I would not force him to do civil engineering again." ”

"The past is the past, the present is the present, and I don't think you will refuse if you go to him now, Your Excellency Prophet."

Ge Lipeng's words surprised Li Yu slightly.

"Really? Do you know where he is? ”

"He was supposed to be in the little village south of the tower, where a windmill mill had recently been built, and he went over when he heard the news."

Li Yu wondered if there was something wrong with his ears, and someone's resounding sentence "Civil engineering, dogs don't learn" was still in his ears.

But no matter what, the prophet of the Shuangxiu Sect still found He Chaoyang according to the direction pointed out by Ge Lipeng.

From a distance, Li Yu saw He Chaoyang with an iron pot on his head, holding his hands behind his back on the ridge, inspecting the half-built windmill mill.

If you got closer, you could hear him speaking a broken lingua franca, jumping out word by word, and for fear that the nearby craftsmen would not understand, he crouched down and drew on the ground.

When Li Yu walked over, he was talking about the rise, "This ...... Structure, tired, understood? ”

Li Yu couldn't listen to it anymore after listening to it for a while, so he said to He Chaoyang, "You tell me first, and I'll translate for you." ”

He Chaoyang heard the voice behind him, turned his head sharply, and found that it was Li Yu, and couldn't help but be a little embarrassed.

The halfway point of the painting just stopped there.

"Prophet Merlin, you, why are you here?"

"I'm here to find you."

"Looking for me?" He Chaoyang's face was flushed, just like being caught in bed for an affair, and his back was soaked after a while.

"You finish the business at hand first, and we'll talk later."

He Chaoyang nodded, with Li Yu's help, he only used a few simple words to explain the problem clearly.

Under the admiring gaze of the craftsmen, the two walked back.

Li Yu said, "I thought you hated civil engineering." ”

"Well...... He Chaoyang hesitated, "I used to hate it, but now I don't hate it." ”

"Why?"

"Because I seem to have found the joy of simple building again, just like building Lego when I was a child, and I can help others, so I will return it...... It's quite fulfilling. ”

He Chaoyang finally said what was in his heart, and at the end he sighed, "I realized that what I hated was not this profession, but the industry environment at that time."

"Overtime has become a habit, desperately kneeling and licking Party A, blindly pursuing speed, and constantly reducing costs...... But what am I, even if I hate it, it's useless. He Chaoyang laughed at himself.

However, soon a smile appeared on his face again, "It's different here, huh." I feel like I'm getting in love with civil engineering all over again. ”

"It's good, I was thinking about what you could do in the future, although you said that you can do anything except civil engineering, but it is always better to be able to do a job you like than to find a job to make a living." Li Yu said.

"It just so happens that I also have a job to trouble you, and it stands to reason that after coming here, I will go to a language school for three months before I officially start working.

"But the situation in various places has been turbulent recently, and I have to prepare in advance, so I can only let you study and work at the same time, but you can rest assured, the rest time will not be less no matter what, and the work will be paid wages and bonuses normally."

He Chaoyang scratched his head, "Actually, I've already found a part-time job as a construction consultant for Miss Ireya...... We met before in the new town. Mainly because I'm a little excited myself, I want to walk around the construction site.

"So I think I'm ready to work, you can rest assured that you can leave it to me if you have any tasks, and I will definitely give you quality and quantity to complete."
