"I was shocked. Why did this happen?" Zhang Yanling smiled.

Xu Youtang wiped the sweat from his face and sighed, "I was shocked too. My father didn't say that there would be a blast in his notes. Could it be that I made a mistake? Marquis, I feel more and more unsure. I'm afraid I'm going to make this furnace of iron into scrap iron."

Zhang Yanling saw Xu Youtang's face red and her hair was soaked. He knew that she was under tremendous pressure and felt pity and admiration in her heart. A seventeen-year-old girl who shoulders such a heavy responsibility can imagine the pressure in her heart.

"Don't worry, I think it should be nothing. Isn't this the stove calmer again? It should be nothing big. Besides, what if the practice is useless? It's just a waste of pig iron and charcoal. If you fail, you will be exploring and starting again." Zhang Yanling comforted.

Xu Youtang smiled at Zhang Yanling gratefully and thought to himself: He just reassured me, he doesn't want to fail, and he can't let him down.

Within one incense stick of time, three sprays and infusions of white soil were performed. This is also the key point of the smelting process. After each spray of white soil, the molten steel needs to be tumbling and fused, and the molten steel below was tumbling and then added. After three times, the addition of the molten steel and the molten earth in the whole furnace can be more evenly.

Although Xu Gao's notes and has been studying them carefully for a long time, there are absolutely no fixed patterns to follow in real practice, in the mastery of the heat and the time for adding white soil. Everything needs to be judged based on the judgment of the furnace water form and temperature. This is really a challenge for Xu Youtang. In fact, even she herself did not have the confidence to guarantee that she would succeed later.

Finally, three hours later, it was time to produce the steel. Everyone gathered together again and wanted to know what kind of results could be produced in this complex furnace after a series of complex smelting processes guided by a little girl.

The iron chains roared, and the iron wheels slid on the thick cross-bowl, moving the huge cast iron crucible to the notch of the furnace water tank. Several strong men hooked the iron ring embedded in the circular furnace door with iron hooks. Seven or eight men tried hard together, and the circular furnace door was pulled open. Sun Wanhou went into battle personally, holding a long and heavy iron rod in his hand and hit the thin dark red inner wall on the inside and outside of the furnace several times, opening up the passage inside and outside the furnace.

For a moment, white light was dazzling, and sparks were splattering everywhere, and a white fire-emitting steel tilted out from the notch. Suddenly, a scorching steel was burning in the air, emitting flames, shining with dazzling light, and the choking blue smoke quickly spread.

Sun Wanhou roared loudly. The iron chisel in his hand poked into the furnace, speeding up the speed of the steel flowing out.

Several furnace workers next to them also followed with iron chisels in hand, and the steel rushed out quickly and poured into the crucible. Soon, half of the steel was injected into the huge crucible in the bowl. No steel flowed out of the smelting furnace soon, and the rest were some black and red semi-solid objects.

The iron chains roared, and the crucible, shaking in the air, moved to the end of the cross-bowl, and then hung over the iron ingot mold on the soil platform.

Zhang Yanling didn't care about the burning of the steel, so he walked closer to take a look. The molten steel in the crucible was rapidly becoming dim. Li Dagen shouted loudly, and several furnace workers acted quickly, manipulating the crucible to inject the mould into the iron ingot mold below. After casting the five molds, the crucible had already been emptied.

"Five hundred kilograms of green iron, the maximum amount of molten steel is 200 kilograms here. What's going on? Is it useless?" Li Dagen frowned.

Xu Youtang looked very excited and stared at the Tiexue: "It seems to be done."

Zhang Yanling couldn't see the clues, so he hurriedly asked, "Is it done?"

Xu Youtang said: "Dad's notes say that after smelting, only half of the steel was obtained and half was slag. Isn't this match? Also, the steel condensed with a dark blue color. Brother, look, does the surface of the steel cooling water have a dark blue color?"

Zhang Yanling squinted his eyes and looked carefully. He saw that the black condensed surface seemed to have a hint of blue tone. It did look a little different.

"So that...has it been successful?" Zhang Yanling was ecstatic.

Xu Youtang said: "We have to wait until everything cools down before seeing it. I'm not sure yet."

Seeing that her face was covered in sweat and her face was red with hot red, Zhang Yanling hurriedly said, "Don't worry about it for now, go, go cool down quickly. You'll have heatstroke in a while."

Everyone finished work and rested. Today, the kitchen was filled with meals and dishes, which was very fragrant. The furnace workers successfully opened the furnace today. Although it was unbearable, they were also happy. They sat happily under the shade of the shanty town and chatted with the house.

Zhang Yanling sat in the room with Xu Youtang for a while. He felt that Xu Youtang was a little restless. He thought she was still worried about the result of the smelting, so he comforted her.

"Don't be too psychologically burdened. If you succeed, you will succeed. If you fail, you will try again. Failure is the mother of success. If you fail, you will learn from experience. Besides, you may not fail."

Xu Youtang whispered, "No, I feel uncomfortable. My clothes inside are soaked. There is no place to change them. It's so uncomfortable. I really want to take a shower and change my clothes."

Zhang Yanling smiled and said, "So that's it. That's not easy? Just go to the reservoir below to take a shower."

Xu Youtang blushed and said, "How can this be so in broad daylight? Isn't it so embarrassing to be seen?"

Zhang Yanling smiled and said, "There are invisible lotus leaves. Who can see them bathing among the lotus leaves? I will give you the wind, who dares to get close?"

Although Xu Youtang felt it made sense, he was a little shy and hesitant after all. Zhang Yanling stood up and came and said, "Let's go, what's there to hesitate? Take a clean bath and feel comfortable all over. How comfortable it should be to change into clean clothes. Didn't we bring some snacks and dry food? After we packed up, we would eat something under the shade of willows and have a breath of air, so comfortable."

Xu Youtang's girl's character could not withstand this temptation. She could have a picnic on the dam with her lover and get along alone, so of course she would not refuse. So she hurriedly got up and packed a big package and held it in her hand.

Zhang Yanling went out to greet everyone, saying that he wanted to go to the foot of the mountain with Miss Xu, and there was no need to send anyone to follow him. Chen Shiyi and Zhang Yin knew it well, and knew that the relationship between the two was extraordinary, so they nodded and agreed.
