Li Ruixiu didn't know that the craftsmen were frightened, his current position could be regarded as the closest to the converter except for pouring molten iron, he urged the craftsman to add three things to the furnace, and he wanted to stand on the shelf and take a look at the reaction inside the hearth, so that he could only dimly see the traces of molten iron.

Li Ruixiu endured it for a long time and still didn't hold back, let Li Zhan help himself to the shelf, let go of the bamboo cane and climb up, and held the railing step by step to quickly reach the craftsman who dumped the molten iron.

Li Ruixiu could see the red hearth through the cloth belt, he reached out and pulled off the belt, his eyes did not dare to squint at all, he opened his eyes and looked, the furnace was a dazzling red light, which made him shake his mind for a while, the molten steel rolled, a layer of black impurities floated on it, the heat wave rolled up, straight on Li Ruixiu's face, he took a step back and touched his cheek, and waited for the temperature to be a little lower before ordering someone to pour the ground limestone into it, this step is for desulfurization, he has never done this before, this time I want to test it, This is said to reduce the amount of oxygen and coke used, making it more energy-efficient.

Li Ruixiu scoffs at energy saving, but he is willing to try new reactions.

The furnace gradually turned over the iron, and the burned molten iron was also filled, Li Ruixiu estimated the time and ordered the lower part to start turning the furnace and pouring out the molten steel, not taking the dirty liquid above, not taking the slag below, only taking the molten steel in the middle, and pouring it into the mold lined up in a row.

The splashing molten steel is diverted out, the craftsmen are dressed in thick clothes and trousers, and the molds are filled with ease, and then there is a long wait.

Li Ruixiu turned his back to everyone and recorded his experience of observing converter steelmaking, because it was almost dark, and there was always a red spot of light in his eyes without the light of the furnace fire, so he reluctantly put away the notebook, he groped his way down the shelf, and went out to wait.

I didn't feel it inside, but I felt the cold wind and fresh air in the mountains when I went out, and I thought that I had just inhaled a lot of steelmaking poisonous gas.

After waiting for a long time, I followed the craftsmen to eat a big pot of dishes, and the time was almost up. The experienced craftsmen saw the exposed part and knew that it was time to open the mold, and smashed open a mold under the gaze of a group of people. The triangular thorn inside was wrapped in some impurities and leaked out, and the craftsman carefully picked it up and used tools to clean the surface of the triangular thorn, revealing the silver-white weapon inside.

The color seemed to be steel, but everyone was not convinced, and looked at each other hesitantly, and before they could say anything, the craftsman who opened the mold slashed horizontally to the ground with a three-edged thorn. He has been striking iron all year round, and he knows that this kind of weapon is brittle in the middle, and he can judge the weakest link by smashing it horizontally.

The tip of the triangular thorn poked into the ground, causing the people around them to let out a soft cry, and they didn't know if they wanted to see a broken weapon or an intact weapon, but they couldn't help but cry out for the result.

The man pulled out the prismatic thorns from the ground, inspected them and found that there was no damage, and after thinking about it, he poked the thorns downward and stabbed them into the ground fiercely, and half of the triangular thorns sank into the earth, but the craftsman's hand was scratched because the thing was not used as a gauntlet. Although the prismatic thorn had not yet been opened, his movements were a little too forceful, and his palm slashed to the corner of the tail.

It was only after a long time that everyone came back to their senses and discussed, one accompanied him to clean the wound, and the others stepped forward to smash open the mold, as if opening a treasure chest. While cleaning up the attachment, they secretly bent and tested the hardness of this thing, and everyone was surprised.

Li Ruixiu picked up a few prismatic thorns at random, lit a torch in the corner to watch, and knocked on the wall to test the hardness, he didn't have a professional instrument, and he couldn't measure the quality of this thing, but there were no traces of bubbles on the observation surface, the molten steel temperature and smelting time should be enough, and the hardness and toughness were okay if he stabbed the wall, and there was no problem with killing people.

The craftsmen were excitedly communicating noisily, Li Ruixiu took advantage of this time to leave, he took three and asked Li Zhan to help him back to the room, and further observed to look slowly in the sun, now this flickering torch will not work.

The craftsmen hurried up to open the mold, only four were not good, and the others were successful, and some people began to sharpen the blade in a hurry, and they were very busy.

The commander was ready to thank the horse and say a few kind words, but found that the other party was long gone, so he could only turn around and pick up a few triangular thorns that had been cut in advance, and run to the camp down the mountain with torches, and this good news should be told to the prince as soon as possible.

Wang An looked at the two triangular thorns on the table, one was presented by Li Ruixiu, and the other was presented by the mechanical word camp today, there was almost no difference, the blades were shining with cold light, and the whole body had the color of good steel.

Summoned the commander to inquire carefully about the manufacturing process, and Li Ruixiu didn't get started during the whole process, that is, he ordered people to operate according to his instructions, and there was no hiding from him.

King An pondered, he always felt that things went smoothly and unexpectedly, suppressed the uneasiness in his heart, and carefully inquired about the process, there was a special person on the side to record all the steelmaking process, just waiting to copy it again.

He nodded, and instructed his subordinates to re-refine the three furnaces of molten steel in Li Ruixiu's back mountain, and if all were successful, they would set up a workshop in the Chinese army according to the drawings.

At noon on the second day, the subordinates of Princess Yongning's mansion sent clothes for four o'clock, including court clothes and official uniforms, all of which were made of tribute satin, so that the embroidery girls in Jiangnan rushed to make them overnight, which was very different from the court clothes that Li Ruixiu bought in a hurry that day, and sent charcoal, bacon, whole fur, and cloth to be lifted.

Li Ruixiu looked at the open shelf, knowing that these things must have been carried all the way from the west of the city to the north of the city, so that people could watch the princess all the way to the deep meaning, he had no choice but to accept the things, because Zhang Da was not there, he could only let Li Zhan lead people to the warehouse.

Not long after that, the Zuo Zongren came again, urging Li Ruixiu to vacate the main courtyard for the princess to stay, the status of the monarch and the minister has been decided, Li Ruixiu can not struggle, fortunately, the third courtyard in the back is very spacious, and there are also east and west wings, the sect people inspected, and also agreed that Li Ruixiu will clean up this courtyard for the princess to prepare, the Chinese military craftsmen who live behind are making steel in the back mountain at this time, and the Zuo Zongren just entered the garden and slipped around, it seems that it is indeed an empty courtyard, so he didn't say anything.

Li Ruixiu sent everyone away, he couldn't help but have a headache, he never thought that there were so many things to open the door and set up a household, so he could only call Li Zhan and ask him to go to the tooth store to urge, willing to pay a high price to buy a steward.
