"Big iron box? Where did our three rows of big iron boxes come from? The soldiers did not know, but when they ran out of the camp, they saw twelve large iron boxes standing next to the pile of metal materials.

These are the iron boxes that Lu Haoyu carried from the collection room when he told Hou Xiaoxian to leave. That was the night before, when he dismantled the Divine Mind Instrument, the iron box removed from it, no more, no less, exactly six pairs. There are large and small, and they are the sand mold boxes he prepared for casting.

Twelve pairs of large and small boxes were carried to the camp one after another, and Lu Haoyu designated a pair of medium boxes as the first sand box, and began to instruct everyone to start packing the reconciled sand.

Then, he called the three platoon commanders aside, arranged five people for him, and asked him to make sand cores. The sand core is the internal structure of the round pot design, that is, the internal capacity of the round pot.

The third platoon commander is worthy of being a little expert in science and technology, and his ability to accept drawings is also extraordinary. And Lu Haoyu is to guide the details, everyone has little experience in casting sand molds for the first time, and it all depends on Lu Haoyu's on-site attention.

It didn't take long, two sand boxes and a sand core were stacked, the next step was to fill the sand, the 1mm sand particles screened before, Lu Haoyu used seven layers of water to stir into a slurry paste, fill these muds on the surface of the sand mold and sand core, and then polish it Seiko. This is not only for the sake of aesthetics, but also to ensure that there are no obvious marks after pouring. After all, the grinding parts are the inner and outer walls of the casting after molding.

When the sand mold was close to completion, Lu Haoyu nodded and called the three platoon leaders over, "The final grinding work will be handed over to you, it will take an hour for the casting to condense, and the first team will be replaced when it is done here, you and the first team will be responsible for resting, and let the second team take over the work of screening sand and gravel, and by the way, mix it into a pulp, and prepare the second casting."

"Commissioner, let me work with the second team, think about the casting process of the third row is about to succeed, I can't sleep."

"No, the first team has no experience in sand casting, and I still need your guidance." Lu Haoyu sternly rejected the application of the third platoon leader, what he decided, I am afraid that it will be difficult for Ye Guchen to change.

The casting row was carried out in an orderly manner, and Lu Haoyu walked out of the camp, using a skateboard to slide quickly, out of the bedroom, and into the hall.

At this time, he felt that the temperature in the hall was higher than usual, Lu Haoyu followed the temperature induction, and walked to the door, the scorching high temperature came from outside, and now it is a rainy day, it stands to reason that the outside world should not be so hot.

Outside the door is the outside world, since Lu Haoyu was born in the Heavenly Dream Troupe, he has been staying at home and has not breathed the air of nature.

In fact, he had mentioned it to Ye Guchen a few times, but the latter had always disagreed with him walking out of the gate of the Heavenly Dream Troupe, and kept emphasizing that it was very dangerous outside, and the Heavenly Dream Regiment was the best safe haven, and when he cultivated to a certain level, such as the tenth level of forging his body, he would take him out to see the world.

It's a pity that Lu Haoyu can't lift his spirit at all to see the world, he was not just a human being in his last life, he was still a true god of the universe, and he had never seen anything in the world, so he obeyed Ye Guchen.

Now, he had guessed that Ye Guchen was smelting molten iron outside, and there was no smelting furnace in the entire room, so needless to say, he must be smelting molten iron outside.

He had downloaded level 1 of smelting, and knew that the temperature required to smelt molten iron was extremely high, and the room was the world of the soldiers of the Heavenly Dream Regiment, and if he was not careful, he might cause casualties to the soldiers, Ye Guchen naturally did not dare to risk the army, and all dangerous things would be carried out outside.

Lu Haoyu hesitated for a moment, and used all his strength to knock the door open a crack, of course, this was because Ye Guchen forgot to lock the door.

Coming to the outside world and looking up at the sky, he took a deep breath, this world is so big, and he has a different feeling when he is reincarnated.

It's not bad to be a creep, at least you can look up at the sky and look farther away.

Because of the humid weather, Lu Haoyu had just walked out of the door, and the accumulation of water in his scientific and technological essence had recovered to 100%, making up for the consumption caused by forging his body by the furnace in recent days.

Feeling the warmth of nature, Lu Haoyu was ready to look for Ye Guchen, and he was more concerned about the condition of the molten iron.

Looking into the distance, this is a huge courtyard, huge is of course in his eyes, but in fact it is just a small courtyard, in a corner of the courtyard, Ye Guchen has a dark face, and is anxiously paying attention to the molten iron in front of a half-person-high smelting furnace.

"This is a small electric arc furnace, and it is very new, and it can be heated to a high temperature of nearly 2,000 with normal household power supply to refine the molten iron. It seems that the level of science and technology in this world is not low, at least the industrial technology of mankind is on par with the modern world in the world. But isn't Ye Guchen an orphan, where did he get the electric arc furnace, and why does he have such a deep family background? There is also a man who lives in a room alone, whether he is deceiving me, or is he hiding something else. ”

Seeing that the molten iron was about to be baked, Lu Haoyu didn't have time to think about it, and took a step forward and wanted to run over to help.

Oops, the yard is sandy, far less flat than in the house, and it is impossible to use pulleys at all. He could only take the pulley off his left foot, throw it in the doorway, and try to walk.

As soon as he took a few steps, a breeze hit and blew into his body, and his right leg suddenly felt that it was no longer weak and weak, and there was a sound of stepping on the ground.

"My right leg has an affinity with the wind in nature", thinking of this, Lu Haoyu was very happy in his heart, no wonder he hadn't found it before, because he was hiding in the room and the wind was isolated, and he couldn't absorb it into his body at all. 、

Now he runs in the wind, and not only is his right leg strong, but he is also extremely fast, even comparable to a pulley. Unfortunately, the breeze in this dry environment was gusting, and the wind that could be absorbed was so small that he couldn't run after running a few steps and consuming the wind energy storage. But even if you go, it's much faster than before.

It turned out that none of his limbs were crippled, his left arm was friendly with water, his right arm was friendly with ice, his left leg was friendly with earth, and his right leg was friendly with wind.

Lu Haoyu didn't spend a lot of time running in front of Ye Guchen and stopped the master who was blackened.

"Hey, are you new to EAFs? It doesn't look like you're very skilled, how is your molten iron smelting? I've done all my preparations, but that's all you need. ”

"How did you find this, it's dangerous here, get out of here."

Ye Guchen probed and saw Lu Haoyu, who was small on the ground, with a worried face. At this moment, a few iron ore slags were "touched" and fell in front of Lu Haoyu.

Pls. Sandalwood is guilty, the book is a little slow, the progress is slow, and the layout is too large, which is not conducive to the beginning of the newcomer's work. However, the book has gradually spread out, and the follow-up will try to improve, I hope you will comment more, give Sandalwood valuable comments, I am waiting for your guidance in the book review area.

In addition, the originally planned double opening "Return to the Flood Wilderness" finally decided to concentrate on the writing of the small soldier faction and no longer involved any energy. I've been busy at work lately, but Sandalwood tries to find time every day to read book reviews. Finally, thank you for your support, comments, favorites, clicks, recommendations, and rewards. Sandalwood must do her best to write the creep faction well.
