Feng Yuheng is still quite interested in walking sideways, but now she has to face a very headache: teach Xuan Tianming to read simplified Chinese characters.

She told Xuan Tianming: "I write like this entirely because I am lazy. I want to write a few less strokes. Anyway, I know that this is what I mean."

Xuan Tianming didn't believe this, so he simply said: "You can tell me directly that this is Persian."

She spread her hands: "Although I really want to say that, in fact, it is really not a Persian word. If you insist on saying it up, you will have to break it down sooner or later."

Xuan Tianming wanted to say that you will have a lot of trouble in the future, but you still couldn't bear to expose it. Under Feng Yuheng's guidance, it began to read the "Feng's Steel Making Guide" written in simplified Chinese.

The so-called "Feng's Steelmaking Strategy" is actually the steelmaking process handwritten by Feng Yuheng. From slag making and slag production to the final silicon increase, end control, and steel output, there are a total of nineteen steps, each step has a detailed explanation and explanation. Moreover, she has also analyzed some problems that cannot be solved in today's era, found a method of replacement, and explained them in detail. However, this method of replacement has not been tested, and I still don't know whether it can be successful. This is also one of the biggest difficulties in their steelmaking.

Xuan Tianming's ability to accept was quite fast. Feng Yuheng told him some rules for reading simplified Chinese characters and guided him to read a few. After reading them, he could figure it out by himself, but there were some too professional narratives that still needed Feng Yuheng to explain.

An hour later, he finally put down the strategy and said to Feng Yuheng: "Making steel is not an easy task. After reading this, I confirmed its difficulty even more. I can't guarantee that it will succeed, but at least we can try it. If it doesn't work once, it will be twice, and if it doesn't work twice, it will be twenty times. No matter when the test is done, I believe it will succeed. God will not be so unwilling to be so sorry for my great success."

She nodded and began to organize the furnace while saying, "This has nothing to do with God's pity for Dashun. Although I have never refined steel with my own hands, I have watched others practice with my own eyes. It's just that we can't have some equipment that needs to be used in some aspects, so those alternative methods are the main places for our experiments."

Xuan Tianming also became serious, turned his wheelchair and began to prepare with Feng Yuheng.

The first step in steel making is slag making. Compared with the subsequent steps, this is considered simple. In other words, it is simple from slag making to slag output and then to the stirring of the solvent pool, which is just blowing at the bottom of the electric furnace. I don’t know if the existing huge bellows can be achieved. Especially the oxidation period and decarbonization period of the subsequent step, which is the time to test technology.

The two of them didn't care about their image, and even Xuan Tianming got off from the wheelchair and sat directly on the ground. Feng Yuheng served as technical guidance and took action. Xuan Tianming was the main operator.

"Slag making is the operation of adjusting the slag composition, alkalinity, viscosity and its reaction capacity in steel and iron production. The purpose is to make a metal with the required ingredients and temperature." She said, and he took a step, and the amount of everything, the heat and time of each furnace were strictly stipulated. He did not dare to carry it at all, but unfortunately, after the slag was released, Feng Yuheng shook his head: "No, the oxidized slag is not clean enough, and it is easy to cause phosphorus return." Thinking about it again, "I think there is no problem with anything else, so it is still the mastery of time. Although we calculated it very seriously, it is still not accurate enough."

Xuan Tianming nodded and said, "Come again."

"Wait." She held his wrist, thought about it, and simply removed a wall clock from the wall of the space.

Xuan Tianming saw that she pulled out something that was so big that it was impossible to put into her sleeves from her sleeves, and her hair stood up. Fortunately, she had the experience of the soldier being poisoned a few years ago. He was the one who had seen this girl pull out a butt from her sleeve. Although she was shocked now, she was not so shocked that she regarded Feng Yuheng as a monster. What's more, Xuan Tianming understood that things were not the same as being a monster. In this way, his young wife would have been soaked in the river to sacrifice to the gods.

"This thing is called a clock." Feng Yuheng was guilty and did not dare to explain the origin of the thing. He only talked about the usage of the clock with ease. She told Xuan Tianming: "The three pointers on these are called hour hand, one is minute hand, and the other is second hand. The reason is the same as the sundial we use. However, the sundial is twelve hours, and the clock is divided into twenty-four hours, which means that one hour on the sundial is equivalent to two hours of the clock."

She patiently explained the clock to Xuan Tianming and said again: "This process of making a scum takes one hour and forty-five minutes. This time we use the clock to accurately time it and try again."

"Okay." He nodded, pointed to the twelve o'clock position directly above the clock and said, "The minute hand and the money needle will start here. This time, it's not bad at all."

The two of them made all the preparations for doing it again, staring at the last two minutes on the clock, looking at it one by one. Finally, the ticking second hand walked through the last square, and as soon as it fell at twelve o'clock, Xuan Tianming's movements immediately started to operate.

Feng Yuheng also stared at him nervously, and said the steps one by one as he moved.

Xuan Tianming remembered it very quickly. After the last test, he could have completely remembered the entire process in his heart. His movements were so skillful that he looked like a veteran. Even Feng Yuheng had to sigh that this person's brain was really good and he was so decent in everything he did.

Finally all the processes were completed, and the rest was to keep the time. Last time they were guarding the time, they could occasionally say a few words, but this time, even with the clock standing here, the two of them became even more nervous, without a word of communication, and kept staring at the wall clock, not daring to leave at all.

With only one minute left, Feng Yuheng whispered: "Be ready to turn on the furnace, and you have to start the furnace when there are two seconds left."

Xuan Tianming nodded, and his hand had already been placed on the Lu Qiying's handle.

Finally, the last minute ended, almost at the same time when the second hand was approaching twelve o'clock, Xuan Tianming started the furnace with his hand, and a wave of heat hit him. When the furnace shovel was taken out from inside, Feng Yuheng screamed: "It's done!"

As soon as these two words were spoken, even Xuan Tianming was excited, and then he looked at the scrap on the stove shovel, and asked Feng Yuheng uncertainly: "It's really done?"

Feng Yuheng nodded, "Success! Not only did you succeed, you also created the best scum. With these things, our subsequent steps will have a solid foundation. Xuan Tianming, you are really capable!"

She praised her sincerely, and Xuan Tianming breathed a sigh of relief. This was the first step. If she had to repeat it too many times in the first step, her morale would be beaten down.

"We have to continue making slag." Feng Yuheng said: "Although we just try to make a piece of steel first, the middle link has to fail countless times. Every time we fail, the materials in the front will be scrapped. Slag making is the first step, and it is necessary to ensure that the first step is sufficient materials so that the later can be carried out."

Xuan Tianming nodded, "Okay, then we will build a few more furnaces, and we must be more proficient." He said, moving the finished slag aside and putting it on, then turning on the furnace to add materials, and starting a new round of slag production.

This time, he is more skilled than last time, and has a clearer understanding of the time rules of clocks. He almost didn't use Feng Yuheng to remind him that he could operate the entire link alone.

However, Xuan Tianming did not expect that his wife shook her head when she came out this time: "No, the quality is not as good as the last time. It should be because she didn't master the initial temperature. She was a little anxious. You have to keep a little more steady."

"Then come again." He started to fight again without saying a word.

The fourth time, success.

The fifth time, success.

The sixth time, failure.

The seventh time, success.

Feng Yuheng thought in his mind that at first, he would fail once if he succeeded twice, and sometimes he would fail twice in a row. Until Xuantian Ming practice reached the sixteenth time, the success rate began to rise sharply, and ten times in a row were all high-quality products.

Feng Yuheng told him: "You have fully mastered the essence of slag making and slag production. If the finished products we have now are not as good as unexpected, they should be squandering enough. Do these first and continue to proceed. If it is really not enough, then go back and make up for it."

Xuan Tianming nodded, looked at the clock again, and said, "You can't continue anymore, you must rest." He pointed to the clock and said, "According to the time rules you mentioned, it should be the dinner time now, and it is the second day we came to this place. Hengheng didn't close his eyes a day and night, and he didn't eat anything."

"Ah?" She was a little surprised. She was locked in this cave and focused on doing something, and she could not feel the passage of time. However, she didn't expect that it had been a day and a night outside. It was fine if she didn't mention it, but when she mentioned it, she felt a little hungry and couldn't help but complain: "It's true, if we don't go out, don't anyone think about coming in and delivering food?"

Xuan Tianming told her helplessly: "There were six times in between. I even smelled the food, but you drove away the person."

"I drove away?" Feng Yuheng had no idea that he had done this, "How is that possible?"

"How is it impossible?" Xuan Tianming pointed to a pile of empty mineral water bottles on the ground and said, "If it weren't for these things, we would probably die of thirst."

Feng Yuheng ran away!

When did she get so much mineral water? Judging from the number of empty bottles, there are more than half a box. Mom, so many things are taken out of her sleeves, Xuan Tianming must have regarded her as a monster.

Just as he was thinking about it, he looked at Xuan Tianming again, and was surprised to find that this girl was actually... "What are you eating?" Feng Yuheng stopped running to him, stared at the terrified eyes and grabbed the paper bag in his mouth.

Then, she was speechless.
Chapter completed!
