The first time Lu Jing saw the silver-gray stone, he couldn't help but have mixed feelings.
This was the most widely used alloy in his previous life. It was almost everywhere in homes and cities, and it carried too many memories for him. But for this era, tonight is probably the first time it has been used in history. An appearance.
That's right, it's stainless steel!
Unlike other time-travelers who are good at burning glass to make soap, Lu Jing didn't expect that the first thing he tinkered with was stainless steel!
Anyway, Lu Jing recalled the time travel he had seen before, and even the big guys with a background in materials science had never done anything like this.
Firstly, the chromium needed to make stainless steel is almost impossible to extract with the current level of technology. Secondly, the melting point of chromium is also very high, reaching 1800 degrees. With a normal blacksmith's furnace, even with a blower It is impossible to reach this temperature even by pressing in air to assist combustion.
So instead of saying that Lu Jing was a hundred times more powerful than other time travellers, it would be better to say that Chi was simply too powerful.
With the help of formations, spells and the strange thing called Iron Bar, all the impossible conditions for refining stainless steel were put together.
This made stainless steel, which should have appeared only in the 20th century, come out eight hundred years earlier.
Chi saw Lu Jing playing with the silver-gray stone and explained to Lu Jing, "This material is very special. I have never seen it before, and the master has never mentioned it. Judging from the difficulty of my refining, Look, I’m afraid the world won’t be able to find another piece, so this is something that has been completely refined by us.”
Chi's expression became excited when he said this, "It is not afraid of water or fire. Even if I soak it with highly corrosive poison, it will not be affected. It seems that it will not rust at all. This This property is truly amazing!”
However, after Chi praised the small silver-gray stone, he changed the subject again and seemed a little regretful.
"It's a pity... this material is still a bit inferior in terms of hardness and toughness. It may not be a problem against ordinary weapons, but if it encounters a treasure weapon, it is still a bit unsatisfactory.
"But I can feel that your method does work. By fusing two different materials to generate a new material, it seems that you can retain the advantages of the previous two materials and make up for their shortcomings. No, the new material is the same as the previous one. The two materials are completely different.
"If I follow this path, maybe I can continue to mix other materials into it..."
Chi seemed to be lost in thought again as he spoke.
And Lu Jing knew that her idea was right. The piece of stainless steel they had accidentally tinkered with was actually just the most basic and primitive style of stainless steel.
In his previous life, there were actually many types of stainless steel, and they were constantly developing. By adding different metals, controlling the proportions of different metals and the carbon content, stainless steel for different uses could also be produced.
For example, as far as Lu Jing knew, the famous 154cm high-quality stainless steel was one of the best knife steels in his previous life.
Unfortunately, the chemical composition of this thing is much more complicated. It contains far more than just chromium, iron and carbon, and the process requirements are also very high. Lu Jing doesn't know what to do.
But at least Chi is on the right path now, and is much more promising than before when she focused solely on purification.
Chi didn't know what he thought of, and the expression on his face became fanatical again. He wished he could go back and find some materials to mix with. Not only could he mix it into this silver-gray stone, he could also mix in other materials in pairs. Look, no, you can even mix them in threes, or even mix them with each other after mixing.
Chi felt like he was standing in a treasure house now. There were treasure boxes in front of him. If he opened one at random, he would not know what treasure was buried inside.
She hadn't been so excited and happy for a long time, but Chi still didn't forget the purpose of coming here. Looking into Lu Jing's eyes, he invited the latter, "Let's do it together!"
However, Lu Jing refused without hesitation, "No."
Chi frowned, but after a moment he could only give in reluctantly, "We don't have to live together, but it's not convenient to communicate like this."
"It's not a matter of living together." Lu Jing was helpless, but after saying this, he seemed to realize something was wrong, and quickly added, "Of course, living together is indeed a problem."
Lu Jing tried to explain to Chi, "Senior Chi, a young man and woman will only live together when they like each other."
"I like you," Chi said with burning eyes, looking at Lu Jing with undisguised desire, "Can you help me refine weapons!"
"Uh... I don't mean like when I say like."
"Then what is liking?" Chi's brows knitted together again.
"To like is to want to live with someone... forever."
"Then I like you." Chi's tone became more firm.
"…………"
Lu Jing felt that he couldn't go around like this any longer, and if he went around any further, he would be involved too.
To untie the bell, the person who tied the bell must be tied. To solve this problem, we must start from the source. Lu Jing paused and said to Chi.
"Senior Chi, I have told you everything I know. To be honest, I have no idea what to do next to make the most powerful weapon in the world, so even if I follow you back to the cave... …”
"It doesn't matter, we can work hard together." Chi said.
"I want to try to combine all the materials I have on hand and can find. I can feel that this will be a very time-consuming and labor-intensive thing. Maybe I won't be able to complete it until the day I die. , so I need help.”
Chi's extreme passion and persistence for one thing also touched Lu Jing. It had been a long time since he had seen someone as pure as Chi.
But Lu Jing still shook his head when he heard this and said, "Sorry, I can't be a weapon refiner."
"Who said that? You can feel that you, like me, are born to do this kind of thing." Chi said sincerely, "If you give me some advice on weapon refining, I will reciprocate and use what Master taught me. Take something out and share it with you.”
Lu Jing smiled bitterly again, "Senior Chi, have you really not heard about me?"
"What's your business?"
"I don't have any qualifications for cultivating secret power." Lu Jing said, "This is something that almost everyone in the academy knows."
Chi was stunned when he heard this and could not speak anymore for the first time.
Because weapon refiners are different from the blacksmiths outside, even if we put aside the spells and formations required for smelting and forging, the forged weapons and armor usually need to be engraved with corresponding runes.
Lu Jing did not have secret power, which meant that this most important step could not be completed at all.
