The reason why aristocratic families are called aristocratic families is because they do have their own ways of dealing with the world.

In the eyes of aristocratic families, there is only the prosperity of the family and there is no personal benefit. They can sacrifice a lot of things for the family.

Just like Li Muyun, although this guy killed more than 50 people from the Wang family's side, and even the younger brother of the leader of the side branch, when the master found out that this kid could still be chaotic, he decisively threw an olive branch to him, and all of them were thrown out of the Nine Night Clouds before.

In other words, those dead tribe members will die if they die, and the master will not pursue this matter again. This is the only thought that Wang Jie had in his mind after hearing Wang Yishu's words.

...

Let’s talk about it in two ways, let’s talk about our protagonist Li Muyun.

At this time, Li Muyun was not idle either. In an unknown valley, in front of more than ten caves, he was hiding under a big tree holding a bowl of iced grapes and drinking gulplessly. He watched the cave that had been turned off not far away, and a large amount of smoke was emitting from it.

This is the place where coke is refined. After more than twenty tests, this time it was the biggest time to grasp, so Li Muyun came to visit and guide him with great enthusiasm.

"Xiaoyaohou, what exactly is the coke you are talking about? Why do you want to burn black stone and charcoal together?" Fang Yi sat straight beside Li Muyun, with a bowl of iced grape wine in his hand, but he didn't have the heart to drink this thing, just thinking about knowing the effect of coke.

"To put it bluntly, you can also regard it as a kind of charcoal, but its structure is quite special. If it is based on the purpose, this thing can't be found for any purpose except steelmaking." Li Muyun took a sip of the wine in the bowl and said with a shrugged look.

"Just used to make steel?" Fang Yizhi asked with some uncertainty.

Li Muyun often habitually deceives people. Fang Yizhi hates this, but there is no way to do so, so he can only ask again and again.

"There are other uses, but it can only be used to make steel at the moment. You have to know that I promised the emperor that I can make steel at 500,000 kilograms in five years!"

"That was your own fault, and no one forced you." Fang Yizhi glanced at Li Muyun with contempt, and expressed his extreme disdain for his attitude that he was obviously showing off but still pretending to be infinitely aggrieved.

"No one forced me? Well, you can do whatever you say. Anyway, these 500,000 kilograms of 100 steelmaking must be completed within the limit. If we can't handle it, we will lose our heads together, and no one can escape." Li Muyun said seriously, and at the end, he did not forget to drain the grapes in the bowl, and then said to Fang Yi, who was stunned: "Okay, the temperature in the kiln has dropped almost. You can go over and take a look."

...

A large number of black stones had been moved out of more than ten caves, which seemed to be no different from ordinary black stones.

However, when Li Muyun saw these things, he showed a happy smile on his face. He turned around on Fang Yizhi's shoulder and patted him happily and said, "Old house, it's done, we've succeeded!"

"Success? Isn't these the original black stones?" Fang Yizhi said blankly. As a scholar, he really couldn't see the difference between black stones and coke.

"Don't bother with the black stones in the past, in short, this batch of things is coke now. Just remember it. If it really doesn't work, put one in your pocket. Take it out from time to time. You will know the difference over time." Li Muyun was a little overjoyed, and grabbed a piece of coke that was still a bit hot on the ground and stuffed it into Fang Yizhi's hand.

"Li Muyun, your uncle!" Fang Yizhi grabbed the newly released coke in his hand without any warning, and immediately exclaimed and threw it out. Who said that the honest child would not scold people, but he was not forced to that extent.

However, Li Muyun didn't care about Fang Yizhi at this time, waved to the workers waiting aside and said, "From the future, you will continue to burn the charcoal according to the firing method of this furnace just now. You can burn as much as you can. Do you understand?"

"No!" everyone replied.

They come here to work, and as long as someone pays for it, they do everything the same.

"Foreman, where is the foreman?" After ordering the workers, Li Muyun began to look for the person in charge everywhere. After shouting two times, a thin black man in his thirties ran over and said, "Mr. Hou, are you looking for me?"

"These burned items are loaded for me and sent to the counterfeit village after returning. In addition, I will hurry up these days and make more coke. I will use it to turn back. Do you understand?"

"I understand, Mr. Hou, don't worry, I will urge them to work hard." The foreman pointed his head quickly.

"Okay, let's do it." Li Muyun quickly glanced around and found that there seemed to be nothing to explain. So he finally explained and took Fang Yizhi away from this broken place that was almost terrible.

...

On the way back, Fang Yi looked at Li Muyun with a strange look. He was furrowed and asked in confusion the question he hadn't just asked - what exactly can coke do.

Li Muyun was speechless about Fang Yizhi's curiosity, and finally could only say helplessly: "Old house, do you know what black stone can burn?"

"I know." Fang Yi nodded.

"So do you know the temperature of the black stone burning?"

"This..., how could I know this? It should be very hot, right?" Fang Yizhi thought for a long time, and searched all the memories but couldn't find any records about the temperature of the Black Stone.

Fortunately, Li Muyun did not really ask him to answer this question. Seeing that he was confused, he directly said the answer: "Eight hundred degrees, up to one thousand degrees."

"What is degree?" Fang Yizhi couldn't understand it and frowned.

The concept of temperature was only cold, hot, very cold, very hot in the Tang Dynasty. Like Li Muyun, there was no such concept as measured by specific values, so Fang Yizhi was a little confused.

"This is not the point, the point is that coke combustion can produce high temperatures of 2,300 degrees."

"Two, two thousand three hundred..." Fang Yizhi opened his mouth wide.

"Yes, 2,300 degrees, and the melting temperature of iron and steel is about 1,500 degrees. That is to say, if we use coke to make steel, we can completely burn the iron into water and then add it..."

Fang Yizhi couldn't listen to what Li Muyun said later. At that moment, he only saw someone's mouth opening and closing, and what he said seemed to have nothing to do with him.
