Miao Shang was embarrassed: "Uh, yes, I'm sorry, I just don't think this Xuantie is good." ”

Ye Xuan also lost his temper: "Xuantie is not good, you tell me what is okay, it was you just now, said that the flame is not good, and now it is said that Xuantie is not good, I think you are sincerely looking for things!" ”

Miaoshang touched her nose: "That, it was my sister who said it just now, I am my sister, my name is Miaoshang." ”

Ye Xuan was angry: "Who asked you what your name is." ”

The twins look exactly the same, even the clothes they wear are the same, Ye Xuan is a straight man, where can he tell who is the sister and who is the sister.

Miao Shang muttered: "I mean you recognized the wrong person, explain." ”

"Well, I think it's better not to use Xuantie, but to use selenium ink carbon."

Ye Xuan was also a little surprised: "Selenium ink carbon? ”

Ye Xuan didn't think about using this thing, selenium ink carbon is a kind of carbon that is not too rare, the hardness is not high, the toughness is strong, and sometimes the intermediate or low-level refiners will melt some into it when making longbows.

And Ye Xuan, a refining master, is rarely used anymore, because there are other better materials that can replace it.

Compared to such a soft thing and a hard diamond crystal, they are simply two extremes.

Ye Xuan is not a stubborn person, he also wrote down Yun Chuchu's words before, to be honest, he is also very curious about the "intuition" of the two sisters.

Ye Xuan: "Let's talk about it, why selenium ink carbon." ”

Miaoshang: "First, diamond crystal has high hardness but low toughness, it can be said to be a porcelain doll, it will break when touched, and selenium ink carbon can well supplement its lack of toughness. ”

Miao Qing: "Second, the dark iron is resistant to high temperatures, and when the dark iron melted into molten iron is poured on top of the diamond crystal, the diamond crystal is likely to be unable to withstand it and shatter, after all, the small diamond crystal in your hand is solid, and the miss's sight still has a skeleton made of dark iron. ”

Miaoshang: "Third, even if the diamond crystal is lucky not to be broken, after the whole refiner is cooled, due to thermal expansion and cold contraction, the shrinkage of the two materials is relatively different, and there will be a gap between the diamond crystal and the dark iron, just a slight knock, the outer dark iron will be broken piece by piece like a shell." ”

Miaoqing: "Fourth ......"

The sisters, you and I say one sentence at a time, and occasionally find a few examples to prove that what they say is true.

Ye Xuan was stunned by what the two girls said, as if he felt that he was not a master of refining, but like a student who was criticized by the teacher.

Ye Xuan: "Stop, what you are talking about is nothing more than to tell me that selenium ink carbon is more suitable, or you can operate it." ”

Miao Sheng looked at Ye Xuan's eyes a little wrong: "I'm afraid you have forgotten, we have only learned refining for half a year, and we have just laid a good foundation, and now we have just started it." ”

Ye Xuan really forgot, after all, the two of them really knew too much about the properties of refining materials, and there were many things in it that could only be known after practice.

Ye Xuan: "Then how do you know such details?" ”

Miaoqing: "In order to practice fire control, we often take a piece of material and burn it casually, with a timer on the side, so that when it turns into water, it can turn into water, not one second more and not one second less." ”

The corners of Ye Xuan's mouth twitched: "Burning and playing?" ”

How expensive those refining materials are! They used it to burn and play?

Yun Zhichu: "They often practice this, fusing different things together, and then using different melting points to separate them. ”

Ye Xuan: "What happened to those materials?" ”

Yun Zhichu: "What can be the future, at the beginning, the yard was almost blown up, many materials they said had been melted too many times, and they were no longer pure, and they were too lazy to re-purify, so they kept piling up in the corner." ”

The discarded refining materials in the void space can be piled up in a room, in fact, those materials are not really wasted and cannot be used, but the sisters are almost done with fire control, and no one is too lazy to repurify the pile of materials, so they put it aside.

Ye Xuan seemed to remember something, and suddenly looked at the crystal ball in his hand and said, "This flame is used?" ”

Yun Zhichu didn't think there was anything, he wanted the Samadhi True Fire, and Xueqiu just spit it out: "Yes, this flame is better than their own, so naturally use this." ”

Ye Xuan looked up to the sky and roared: "Tyrannical things, just a master like you can cultivate such a person, a group of little bastards!" ”

Yun Zhichu: "Hey, why are you scolding, annoyed and angry?" ”

Ye Xuan: "Hmph." ”

Yun Chuchu smiled: "Don't hum there, don't do experiments?" What kind of material are you going to use? ”

Ye Xuan fell into thought, Xuantie is indeed hard, but there are also drawbacks, the general direction of the two girls is right, but is selenium ink carbon really suitable?

Why don't you try both?

Ye Xuan touched his chin: "I plan to try both materials, after all, I have worked very your scope, and I don't want to waste it here." ”

Yun Zhichu: "That's fine, practice is the only way to test the truth, and when the results come out, we will know which one is more suitable." ”

Ye Xuan nodded: "That's right, but what you said seems to be particularly philosophical, the refining of weapons is indeed like this, utopian dreams are unrealistic, only by making it with your hands is the real ability." ”

Yun Chuchu rolled his eyes: "Okay, okay, I know you have the ability, let's get ready to start?" ”

Ye Xuan: "Hmm. ”

Ye Xuan touched the crystal ball in his arms, as if he was communicating with it, as if he was familiar with the performance of the flame.

The first time he used this unfamiliar flame, Ye Xuan was also cautious, this flame seemed to be well-behaved in the crystal ball, but he could vaguely feel the explosive power in it.

Ye Xuan wrapped the entire crystal ball with spiritual power, and then separated a wisp of spiritual power to open a small crack.

The moment the crack opened, the crystal ball changed, and the fire elemental, which had been relatively quiet, began to churn, struggling to get out of that tiny exit, and the nature of the burst was unmistakable.

At this time, Ye Xuan was extremely glad that he was cautious, as soon as he came into contact with the flame, he knew that it was bursting, which was even more than what he felt through the crystal ball before.

Fortunately, the opening was small, otherwise he would probably be unprepared, causing the entire crystal ball to shatter.

Ye Xuan could feel that the fire element in his body was suppressed, and he hid in the corner trembling.

What the hell is this flame, and how can it be so oppressive?

Miao Shang rubbed behind Miao Qing and muttered softly: "Isn't it, it takes so much effort to get a fire?" ”

Miao Qing: "Shh, Master Ye Xuan is in contact with the flames of the snowball for the first time, it is normal to be slow to get started, and your first use is not like your hair was almost burned by the fire." ”。

When Miaoqing Miaoshang first came into contact with the refiner, she liked to pull the snowball together, and the two asked the little guy for flames, and the little guy also helped control the size of the flames.
