"Wife, if you don't want your husband to starve to death, you'd better return that thing to me. It's quite filling."
How can she not care about being full? Feng Yuheng looked at the thing in her hand, Yili yogurt. Look, what did she do while making slag? Sure enough, she had the same old problem again. Once she was particularly focused on doing something, she would forget to eat, drink water and other things that the body needed. But she only forgot subjectively, but the brain would still convey the corresponding information, and at the same time, the limbs would be quickly controlled by the brain to do the corresponding things. This kind of control is often not felt by her when she is concentrating on doing things. For example, in the process of steelmaking and slag making, she drank, and then took out bottles of water from the space by herself. When she was hungry, she would also take out food such as yogurt from the space by herself. In short, everything is subconscious behavior, and she can't feel it subjectively at all.
Feng Yuheng was thinking that there was instant noodles in the space. Fortunately, she didn't take out the instant noodles to soak and eat.
"That..." She couldn't pretend anymore. There were bottles on the floor, and a few scattered bread bags. Xuan Tianming was not a fool, and she really couldn't explain it if she didn't say something. So she said helplessly: "If you have something to ask, just ask. I will answer what I can. If I really don't understand, don't pick on me."
Xuan Tianming smiled bitterly and stretched out his hand to her. Feng Yuheng was stunned for a moment, and after thinking for a while, he handed over his hand. As a result, Xuan Tianming said, "Why do I need your hand? I want you to give me a few more sips of that sour and sweet thing. Your husband is really hungry."
All right! She admitted defeat and obediently took the remaining half bag of yogurt. In her heart, she was thinking that when she had some free time, she would stock up on more food. She would put more buns, dumplings, noodles, snacks, and fruits in the space, so that she would have more choices in food in case of any emergency.
Xuan Tianming drank the half bag of yogurt very seriously, and then said to Feng Yuheng: "I don't have anything to ask. I have known that you have something hidden in your sleeve for a long time. I felt strange as early as when we were in the northwest mountains. The sleeves of the clothes you wore were worn out. How could you carry something inside? But you really took out a strange medicine bottle from it, so I was naturally surprised. Years ago, you detoxified the soldiers, and in front of us, you basically took things out without any consideration. I am not stupid or blind, I can see everything."
The more he said this, the more uneasy Feng Yuheng felt. He couldn't help but come forward and half-kneel beside Xuan Tianming: "Since you can see everything, why don't you ask me? Don't you find it strange?"
Xuan Tianming said as a matter of course: "Even if you are a monster, I will still marry you into my family. What's more, you just got a sleeve with hidden secrets by chance, well, or should I say, a wrist."
She couldn't help but admire Xuan Tianming's observation skills, and at the same time, she thought the excuse he gave her was pretty good.
So the girl nodded and said, "You are right. I was indeed able to hide something on my wrist by chance, but this is a big secret, Xuan Tianming. This is known only to heaven, earth, you and me. No third person can know about it. Even my seventh brother cannot tell him."
Xuan Tianming suddenly felt very happy. This girl said that she couldn't let Old Seven know, which meant that in her heart, Old Seven couldn't compare to herself! He always felt that Feng Yuheng treated Xuan Tianhua and Ren Xiang very well, and he also knew that besides himself, Xuan Tianhua had the most special position in her heart, and he used to be a little jealous. But now, hearing her say this in person, he felt very satisfied.
"Okay, I won't tell anyone." Xuan Tianming agreed to her happily, and then stroked the little girl's head, "Let's go, go out and eat something decent, and then have a good sleep. There are still several hard battles to come. If you don't eat and sleep, how can your body bear it?"
The body is the capital of revolution, Feng Yuheng naturally understood this truth. So he nodded and followed Xuan Tianming out of the cave obediently.
The soldiers outside saw the two of them finally come out, and they all breathed a sigh of relief. Ban Zou hurried forward and said, "Your Highness, Master, the food has been prepared. Is it being sent to the cave?"
Xuan Tianming nodded, "Go ahead." Then he let Feng Yuheng push him all the way to the cave.
This time they rested and woke up at noon the next day. Xuan Tianming already knew what she was doing, so Feng Yuheng simply stopped being coquettish and went straight to the guard and ordered, "Go and ask someone to make more food and pack it in food boxes. It'd better be enough for three meals. Your Highness and I will take it into the cave."
Ban Zou was puzzled: "Then it will all be cold." Then he thought about it again, there was a fire in the cave, so he said: "Even if it can be heated by the fire, it will not be fresh. No, no. You always come up with bad ideas."
Xuan Tianming said, "Just listen to her and go get ready."
Ban Zou was used to bickering with Feng Yuheng, but he didn't dare to ask any more questions when Xuan Tianming spoke, so he quickly said, "As you command." Then he went out to order the preparation of meals.
Feng Yuheng was depressed, "You are obviously my secret guard, why don't you listen to me?"
Xuan Tianming told her the truth: "You've spoiled me."
Well, maybe she really spoiled him. But it was good this way, and she didn't want to change. The secret guards were not slaves, and she liked her secret guards to have independent thinking, rather than being like machines that only followed her instructions.
After half an hour, the two finished their lunch. Feng Yuheng performed in front of Xuan Tianming again by stuffing two large food boxes into his wrists, which made Xuan Tianming stunned.
Finally, the two of them entered the steelmaking cave again. This time, they agreed to rush forward three steps in one breath, all the way to the melting stage, and make the slag for the melting stage.
As soon as the stone door of the cave was closed, Xuan Tianming held it in his hand again, and carefully read the next three steps several times before asking Feng Yuheng: "What does this so-called supply of energy to the molten pool mean?"
Feng Yuheng sighed and said, "This steelmaking method is for people with advanced steelmaking equipment. We don't have that now, so we have to find a way to change this." She pointed to the bottom of the paper and said, "Look at the paragraph I annotated. This energy should originally be electricity. Now I want to turn electricity into wind power and use a bellows to complete it. I don't know if it will work. We have to try it a few more times."
Xuan Tianming pointed to a large bellows in the cave and said, "The cave has a vent. The wind force generated by pulling this bellows is not small. I don't know if it is enough. I will pull it in a while. You watch carefully."
"Okay." Feng Yuheng inserted the air pipe into the smelting furnace, poured the slag into it, and nodded to Xuan Tianming, "It's OK, try to pull it. Remember, add force slowly, don't be too hasty at once."
Xuan Tianming said he understood and turned his wheelchair to the side of the big bellows. "Get ready." As soon as he said that, he immediately started moving.
This movement was slow at first, and then gradually increased in strength. The whirring sound of the big bellows sounded very satisfying, and the wind force generated was also very strong, but Feng Yuheng was worried.
The concerns have not diminished in the slightest.
The wind is not as powerful as electricity. How can a bellows be compared to high-voltage electricity? She sat back on the ground in frustration and waved her hands at Xuan Tianming, "No, stop first."
He stopped, not looking tired, "No?"
Feng Yuheng sighed, "It seems that I have to find a way to transform this furnace." As soon as this thought came to her mind, she immediately realized that she had dug a hole for herself again! It was not easy to transform a furnace that could use electricity. Moreover, even if she really built it, this was a small-scale experiment between her and Xuan Tianming. She could draw electricity from space. But what about mass production in the future? She didn't have the ability to get so much electricity.
Feng Yuheng rejected this idea on the spot.
"It won't work." She said helplessly, "It can't be modified. We still have to find a way to maximize the energy. This won't work. Even if you pull this bellows to the extreme, the energy it can provide is still not enough."
Xuantian pondered for a moment and asked her, "You mean to say that the reason for the failure is this bellows? If it can provide more energy, it will succeed?"
"That's the theory." She didn't dare to say it for sure, "At least we can give it a try."
"That's easy." Xuan Tianming said, "The wind power that can be produced here is limited by the environment, but if we go outside, this difficulty can be immediately eliminated. There is also a furnace outside the Xutian Cave, but it is not hidden enough, so we chose to do it inside at first. But the secrecy can be solved. At most, we can strengthen our defenses, which is better than holding it in here."
Feng Yuheng's eyes lit up. Yes, this Xutian Cave had imprisoned her thoughts. She was only thinking about how to solve the problem of steelmaking here, but she forgot that she could go outside.
She perked up and said, "How could I have forgotten this? This is a good opportunity to divide the locations. Some things that can be done in the cave can be done in the cave, and some things that don't have to be done in the cave can be arranged in other places. In this way, there is basically no need for concealment, because it is only one or two links. There are a total of 19 steps in steelmaking, and learning one or two steps is useless."
The two reached a consensus and hurried out of the cave. Xuan Tianming immediately ordered people to move all the things to the furnace outside, and then ordered people to artificially isolate that place to create a quiet space.
Some soldiers brought a bigger bellows over. This time, Xuan Tianming didn't need to do anything. The soldiers lined up to help.
Feng Yuheng called a few people to help pull the bellows. This bellows was so huge that it required the combined efforts of four people to pull it. She explained the key points several times, and the four soldiers tried it repeatedly, and finally they were able to control 70% to 80% of the strength.
Feng Yuheng connected the air pipe to the furnace again, and then pulled Xuan Tianming to sit beside the furnace to observe carefully, and from time to time he had to direct the soldiers' strength. Even so, he still failed four times in a row.
Feng Yuheng was not discouraged. She told the soldiers: "If it is so easy to make steel, it will not be an advantage for Dashun. You are able to participate in the first steelmaking operation. This will be recorded in the history of Dashun. You should be proud of it."
With her encouragement, the soldiers shook off the gloom brought by failure and devoted themselves to work again.
When the soldiers pulled the bellows for the eighth time, Feng Yuheng's eyes, staring at the furnace, suddenly flashed with excitement.
Xuan Tianming saw with his own eyes that the light in her eyes was getting brighter and brighter. Finally, everyone present heard a beautiful and heart-throbbing voice shouting, "It's done!"
