"Don't check, I've vomited it all, and the molten iron is not poured into my stomach, but in my dantian."

When it came to the dantian, Hou Xiaoxian was silent, others may not know, but he knows very well, as a master of the Tongmai realm, and with the memory of his previous life, he knows that the dantian is the main part of human cultivation.

The first two stages of the cultivation realm are forging the body and passing the pulse, and the highest realm of the pulse is on the dantian. This kid is only a forging body level three, the dantian can hold molten iron, and the amount of storage has reached such an astonishing amount, but this is too inconsistent with the growth law of the little soldier, how much will he subvert the common sense of my cognition? Or, he will really bring miracles to the Xuanwu Empire.

"Are you sure you spit out all the molten iron? Is there any molten iron left in your dantian? Ye Guchen's heart was full of worry, and he kept asking questions.

Can you not worry, the facts are in front of you, Lu Haoyu inhaled more molten iron in his body than the total amount of molten iron in the pouring cavity and metal furnace.

"I think I should have vomited out, right? But it seems that there is still something left in the dantian. ”

But no matter how much he vomited, he couldn't spit it out, and what he couldn't spit out made him feel like a small pool of viscous objects with a high concentration, like sticky phlegm, clinging to the dantian, no matter how he coughed, he couldn't spit it out. ”

In order to spit out the unknown objects in the dantian, Lu Haoyu was so red that he couldn't spit it out, but in the end, he didn't spit out anything, but he held back a fart below, which made him blush with shame.

In order to divert everyone's attention and avoid embarrassment, Lu Haoyu ran back to check the only cavity.

Although the temperature of the cavity has not subsided at this time, he found that the casting inside has completely solidified into a solid state, which is not right, doesn't the textbook say that it will take an hour to completely cool and form? It's only been a long time, and it's too fast, Ye Guchen was shocked in his heart.

Lu Haoyu didn't know why, the facts in front of him were beyond the casting technology he mastered, and he used the calculation level 1 to make a simple calculation in his brain, and he found the key reason, the molten iron spit out of his dantian has some mutations, and it can't be compared with ordinary molten iron.

What kind of sword will be produced by the molten iron that has been improved by the dantian? With doubts, he slowly removed the sand and began to pick up the parcel, which was also the process of boxing. Since he had just drunk molten iron, he had become more aware of his antibodies to fire, and he was not afraid of high temperatures.

The grit was peeled off while beating, and after the sand mold was peeled off layer by layer, the casting was finally revealed, and a small pouring pot with a bright silver metallic luster was presented to everyone.

"Wow, it's so beautiful, it's so exquisite, it turns out that the casting process is so mysterious, it seems that this is high-tech." Including Ye Guchen, everyone began to look at Lu Haoyu with admiration, the seemingly simple and easy process, get a sand mold and pour molten iron, you can make such a beautiful watering pot, this is also amazing, except for the sprue on the edge, this is simply a handicraft, there is not even a little impurity.

Lu Haoyu was also stunned, it doesn't seem to be like this, right? I remember that the castings were all primordial embryos, not only did they not have a metallic luster, but they also had a bunch of raw edges, which were quite rough. Doesn't it have to be ground or forged by hand before it can be finally formed? How did it become so smooth, is this Nima a cast part? It is even more precise than precision mold molding, and it is directly in one step.

After a while, when the temperature had dropped completely, he picked up the watering pot. It's so heavy, it seems to be twice as heavy as an ordinary watering pot, lift it up to see the inside, not only there are no flaws on the outside, even the inner wall is extremely smooth, touch it along the body of the pot with your hand, the texture of the rustle is full, and there is not even a particle impurity, let alone a raw edge. This is definitely a fine product, and it can be displayed in the museum.

Ye Guchen seemed to see the problem, "Lu Haoyu, do you think that what is different from the technology you have learned before?" ”

Lu Haoyu's eyes stared at the perfect small watering pot, and he didn't raise his head but nodded frequently.

"Is that what was poured this time better than any other casting you've ever seen before?"

"It's not just good, it's a thousand, ten thousand times better, it's a world of difference." Lu Haoyu didn't know whether to cry or laugh.

"I noticed something was wrong."

"What's wrong?" Lu Haoyu finally raised his head, he seemed to be tempted by the achievements in front of him, and forgot to calculate and think for a while.

"There is a big difference between the molten iron you spit out and the molten iron I take out of the electric arc furnace. First of all, in terms of color, the molten iron I pour out of the electric arc furnace is pale red, while the molten iron you spit out is bright red, and"

"And what? Is it mixed with other colors? ”

Orange. Ye Guchen thought that he had just lost his eyes, but now seeing Lu Haoyu's excited face, he finally said what he saw.

"Orange pure fire, that's right." Hearing Ye Guchen's affirmative reply, Lu Haoyu was particularly happy, high-temperature molten iron is actually a manifestation of flame, iron is a substance, fire is a natural element, and all substances in the world can be sublimated by fire.

His memory is still there, and his understanding of flames is very clear, and several of his brothers and sisters in his previous life were born to play with fire professionally. And he has a lot of his own mastery, at least the flames of the natural world, which can be easily displayed in the previous life, but unfortunately now the cultivation is lost, the origin of the Great Dao is not there, and everything has to be cultivated from scratch.

The pale red flame, that is the lowest flame, I am afraid that there is not even a thousand degrees, the bright red flame is probably close to three thousand degrees, these flames are real and visible, and they have the same name, called real fire.

The orange flame, which can reach a high temperature of 3,000 to 4,000 degrees, is a flame that is further refined on the basis of the real fire, also known as pure fire. Although there was only a trace of orange in the flame he spit out, it at least meant that he could refine the flame, or through the dantian.

No wonder they were able to make a flawless pouring pot, it turned out that it was using pure fire to refine molten iron.

"Okay, now there is a watering pot, three rows long, the future casting process will be handed over to you, as for the casting process diagram, I am responsible for helping you draw it, and you will arrange the sand mold to build, from today the three rows will be called the casting row." Lu Haoyu was in a very good mood at this time, and casually gave the three rows of sex.

PLS: The flame level setting of this book is the same as "Return to the Flood Wilderness", because after all, Lu Haoyu is a true god who came out of the universe, and "Little Soldier Faction" is one of the series of "Return to the Flood Wilderness". Although "Return to the Flood" has not yet been written, the setting of flames in the previous paragraph has already been quite foundational, see "Chapter 260: Seven Strange Fires" for details.

I also took this opportunity to solemnly promote the book: Sandalwood's "Return to the Flood Wilderness", an innovative Xianxia masterpiece, more than seven years of precipitation, the accumulation of 600,000 outlines, although it is a double protagonist, although the beginning is not glamorous, but it will give birth to lotus step by step, it is Sandalwood's lover, and it is also where all obsessions lie.

Pls. technology and cultivation are upgraded alternately, complementing each other, and they are the same lineage.
