Give the money, and it's easy to do.

This time it's a simple contest where both sides build a weapon at the same time, and then put it to the test, with the winner coming first.

In fact, Hu Tie originally planned to build a sword. But because of his anger, he changed his mind, and he wanted to build a knife, a knife in the style of the East China Sea.

Of course, this was not Hu Tie's temporary idea, he also had his own plans in his heart.

The East China Sea Sword is in a class of its own, and few people know its secrets in the Central Plains. Ordinary blacksmiths think that the Tokai scimitar is bent, but only a few people know that the Tokai scimitar is actually bent during quenching. This is a secret that is not passed down in the East China Sea, and it was also a disciple of Sword Casting Villa who went to the East China Sea to lurk for many years and secretly learned it. It was precisely because of this skill that he brought back that the disciple who had no achievements was deserved to be promoted to a caster, and now he is already a great caster.

Hu Tie wants to use this kind of secret that no one knows in the Central Plains to defeat Gao Li, and let Gao Li know what it means to have someone outside the people!

The other party is menacing, and Gao Li is not idle. In fact, he had been looking at the shed behind Hu Tie, which had been erected for some time, and some iron ingots had been exposed to the air for a while. Pingyang County is hot and humid, and under this environment, iron tools are very easy to rust. But some of the iron ingots used to test the furnace were thrown aside, and after a long time, there was still only a slight trace of rust. Gao Li already knew in his heart that the other party was really prepared.

The iron ingots in front of me are afraid that they are the prototype of stainless steel.

Stainless steel is a steel with a high chromium content and is incredibly tough. The iron ingots in front of me still look rusty, indicating that the chromium content in them should not be high, but even so, the mechanical properties should far exceed that of ordinary steel.

This guy really came prepared.

This time, there were five days to prepare, and after five days, each of them played a Tokai knife. Sword Casting Villa has widely issued a hero post, asking all the senior masters to come to Lizhuang. Masters from all walks of life were already curious about the weapons of this Li Village, and now that someone has invited them, they are naturally happy to see the big battle.

Well, well, fortunately, brother, I'm not unprepared.

The next day, Shapur appeared, and the fire-worshipping merchant looked drastically different from yesterday. The scales on her skin softened and lightened, and she changed her voluminous robe into a distinctly feminine national dress.

Seeing the expression on Gao Li's face, Shapur was also a little embarrassed, and said: "Originally, I wasn't very interested in these things, but after I went back yesterday, I don't know why, I began to miss those colorful clothes when I was a child." ”

Gao Li smiled: "Maybe it's because of the fact that Ren's vein was opened." ”

Shapur nodded and said, "Sword Forge Villa is challenging again?"

Gao Li gave a thumbs up and said, "This word is used well." Gradually, the group of people in the villa are not educated, and they really think that they are still the boss? I can challenge wherever I want? When I am busy with the affairs of Li Zhuang, I have to go to the Sword Casting Villa to go back, and I have to be disgusted and disgusted with them. ”

Shapur said, "If there's anything I can do to help, just ask." ”

Gao Li smiled: "Don't say it, I really have a place to ask you." ”

"Please!"

"Don't worry, go see the eggs first. ”

Under the care of Lizhuang F4, this egg is naturally foolproof. When Gao Li came here, it happened to be Qin Suyan taking care of him. Although this girl has amnesia, she is quite reliable. Seeing Gao Li and them coming, she jumped down from the roof and said, "Report to the owner! No suspicious person was found!"

After saying that, he jumped directly on the roof again.

"Reliable kids. Shapur laughed.

After entering the house, Shapur routinely injected true qi, and this time, the raging flame weakened again, and those meridians continued to extend outward, and things got better and better.

When Shapur had finished infusing all her True Qi, she rested for a moment, and then asked Gao Li, "Is there anything that Gao Gongzi needs my help with?"

Gao Li said: "I remember the last time I said that I wanted to use your ability to control fire, and it happened that the enemy of Sword Casting Villa came to the door at this time. I was thinking of trying out our new material, so I ......"

Shapur smiled and said, "What's so hard about that?

Gao Li brought Shapur to the workshop, and Gao Li built a hut for his experiments.

If you want to engage in powder alloys, high temperature and high pressure are indispensable.

The biggest benefit of powder metallurgy is the ability to achieve extremely complex compositional compliance and extremely material savings. Moreover, Gao Li has always been thinking about such a thing: the steel clamping process and the pattern steel will lead to the disintegration of the weapon under the pressure of high true qi due to different materials. So the use of powder metallurgy to mix high-strength materials and high-conductivity gas materials, will this achieve an alloy with both strength and excellent vacuum conductivity because of the uniform distribution of materials?

Gao Li knew that there was an alloy called tungsten copper alloy, a pseudo alloy with good electrical conductivity and the wear resistance of tungsten. But there is also an alloy called copper-iron alloy.

In short, Gao Li really plans to try them all.

What, what do you say if the attempt fails?

There are still several Donghai knives in the weapons exhibition hall, just pick one at random, Gao Li really doesn't believe that the other party can play with stainless steel.

Gao Li's simple description of the molds was enough to make Shapur's eyes widen. Powder metallurgy, she had never heard of this kind of play before! It turns out that there is such a wonderful metal smelting technology in this world?

"In this way, the air has to be isolated in the reduced state to prevent the metal from oxidizing, so I specially customized this special sintering furnace. Pointing to the big guy in the middle, he said, "This is a ceramic brick, and the outer part is a cast pressure-resistant furnace wall." One on the left and one on the right, each has a station, one is used to apply true qi to achieve high pressure and expel air, and the other is responsible for controlling the temperature of the flame. ”

Shapur didn't seem to understand it, anyway, she had never seen or heard of this kind of thing, she could only listen to Gao Li. In the end, she was already in a fog, and simply asked directly, "What do you want me to do?"

Gao Li clapped his hands and said, "First of all, please let me see your ability to control the flames." ”

Shapur had an iron rod in front of him, and Shapur said: "Actually, our ability to control the flame is not very accurate, because sometimes, there is actually no fire. ”

As he spoke, Shapur gently brushed the iron rod with his hand, only to see that the iron rod was heated in an instant, and it had become fiery red in a blink of an eye!

"Can it be hotter?" asked Gao Li in surprise.

"Naturally. ”

The iron rod got hotter, from orange to white!

Gao Li was shocked, this is wrought iron with an iron rod, and the melting point is 1,500 degrees! And people actually melted it with a light touch? Not only Gao Li, but also several spider demon and bull demon craftsmen who were busy on the side also expressed their incredibleness.

"Where's that pile of powder?" asked Gao Li.

"Here!" a spider craftsman immediately found a box filled with metal powder obtained from the gold-eating ants.

"Can you try to melt this pile of iron powder?" Gao Li asked.

"I'll give it a try. ”

Shapur brushed the pile of metal powder lightly as before, and then he sighed softly and said, "What kind of iron powder is this, and why is it so difficult to heat?"

Gao Li smiled and said, "This is my secret weapon! If I can succeed, there will not be any weapon in this world that is my opponent in the future!"

Shapur also smiled: "I also feel extremely honored to be able to witness the birth of such an artifact!"

"Hahaha! You are so polite! Without your help, I would not have been able to get to this point so quickly!"

After a wave of commercial blowing, Shapur continued to concentrate on heating the iron powder, while Gao Li observed Shapur's movements. In his eyes, Shapur's hands cast true qi, which seemed to be magnetic, and as soon as it left her palm, it would immediately attach to the metal. As the True Qi accumulated, the True Qi began to heat violently.

How does this feel like an induction cooker? It's just that the electricity is replaced by real gas.

It's a pity that Gao Li can understand it, but he can't learn it, this is the natal talent of other people's fire worshippers, and the treasure engraved in the genes.

Eventually, the pile of tungsten manganese steel powder was heated to the limit and finally melted in the crucible.

Gao Li was not sure about the tungsten content in this pile of metal powder, but from the current state, the content was certainly not low.

Shapur waved his hand at the molten iron, and in the blink of an eye, the molten iron was completely cold.

Can it even absorb heat?

That's terrifying! According to the laws of thermodynamics, that's a lot of power!

Click!

The piece of iron cracked.

Instant cooling, which means instant quenching, tungsten alloy itself is hard, not broken is evil.

"What kind of iron is this?"

Shapur asked, picking up a piece of shard. She shook it slightly, and then with some surprise she used her True Qi to break it again, and then she had to break it with all her might!

Just kidding, tungsten alloy, it's still so fast quenching, the internal stress of this metal is explosive, if you can break it, it will be evil!

"It's tungsten steel, and that's my secret weapon to win today. However, I have more to pursue than win, but unfortunately, there is no way to do it today, and we will continue tomorrow?"

Shapur smiled: "A word is a certainty!"

Seeing Shapur away, Gao Li's heart was surging, and he was now full of excitement and didn't know who to talk to!

Tungsten manganese steel is hard and brittle, not suitable for making slender weapons, but what if copper is added to it?

The only reason to stop Gao Li's experiments today is simply because he didn't make enough copper dust. Now, Gao Li can't wait!

No, I need gold-eating ants! more gold-eating ants!
