Li Ling was dumbfounded, looked at it for a while, and didn't understand it at all, what was going on?

Yue Lao looked at Li Ling's ignorant expression, put away the silver essence into his palm, and sighed slightly: "Look at your expression, you know that you don't understand." ”

Li Ling woke up from his observation, nodded blankly, and said, "I really don't understand?" Don't understand at all? ”

"Where don't you understand? Tell me about it? "Yue Lao Zhilu said that Li Ling is just a beginner, and he still doesn't understand some things, which is a normal thing.

"I don't understand, this liquid ball itself is not pure silver essence, but silver concentrate, even if it melts into liquid, it is still silver concentrate, how can you remove the molecular structure in it with a flick of your finger?" Li Ling said blankly.

"Didn't I just say that? The silver concentrate has been decomposed by high-intensity heat energy, and at this moment, it contains the most basic molecules, as long as all the molecules that are not silver essence are eliminated, what remains is the essence of silver essence. Yue Lao explained angrily.

Li Ling still shook his head, still not understanding, after all, this kind of thing was beyond the scope of Li Ling's cognition.

"If you don't understand, then I really can't help it?" Yue Lao was a little discouraged, teaching Li Ling to smelt metals was like teaching a ten-year-old child, and his comprehension ability was extremely low.

The smelting that Li Ling knew in his mind was to use some chemical reactions to refine the part of the metal needed, but there was no so-called chemical reaction at all in the process of Yue Lao's step. It seems that the soil on the outside of the ore has been removed.

Understandably, there are conflicts and contradictions.

"Well, let's experience it for yourself. If you don't experience it yourself, you may not understand it no matter how many times I do it. Yue Lao said helplessly.

Li Ling nodded, and Yue Lao got up from the furnace and gave the furnace position to Li Ling, who got up and came to the furnace. Looking at the rising purple sun fire in it, I was slightly excited in my heart.

"Sit down, Silverspirit. I've already smelted it for you, and the rest is for you to practice with the ten catties of gold ore yourself. Elder Yue handed the thumb-sized silver essence to Li Ling.

Li Ling took the thumb-sized silver essence and said, "Such a big piece of silver essence." Smelted finished. There is only so much left, but such a little silver essence is really heavy, I'm afraid it looks like seventy or eighty pounds. ”

The thumb-sized silver essence weighs seventy or eighty pounds, which shows how high the precision of this silver is.

Li Ling weighed the silver essence in his hand, but he was thinking in his heart. If you can get more silver essence to incorporate into the weapon, then the hardness of the weapon. It should be several notches.

Seeing that Li Ling was showing signs of distraction, Yue Lao bent his finger and knocked on Li Ling's forehead, and said angrily: "What do you want?" Hurry up and take out the gold mine and smelt it, I can't teach you today, I can't report it to the eldest lady. ”

Li Ling pursed his lips, carefully put the silver essence back into the space magic weapon, took out a piece of gold ore, and threw it into the furnace.

Yue beat his chest angrily, nodded Li Ling's forehead and said, "How stupid are you?" Who told you to throw the gold ore directly into it, didn't you see that when I sent the silver essence in, I used a layer of gas to wrap the silver essence? ”

Li Ling was severely taught by Yue Lao, and he had a feeling that the old man had taught him a lesson, and his eyes suddenly moistened, remembering the old man who had raised himself and trained himself to become the number one killer in China.

Seeing that Li Ling's eyes were slightly red, Elder Yue immediately withdrew his hand and said, "Could it be that I used too much force just now and made you a little painful." ”

Li Ling shook his head and said, "No, it's just ...... Hey, nothing, sorry, I won't make that mistake again this time. ”

"It's not a big mistake, I didn't understand it beforehand, I thought you saw it clearly? I didn't expect you to even omit the steps that I could easily see through. Yue Lao said.

Yue Lao's own strength is too strong, thinking that what he can easily perceive, in Li Ling's opinion, it will also be easy to understand, in fact, when Yue Lao just sent the silver essence into the furnace, he wrapped the qi, I am afraid that even the people of the county level may not be aware of this detail, not to mention, Li Ling's vision of a city level honorable level, it is even more impossible to understand.

After Li Ling got Yue Lao's reminder, he took out a piece of gold ore according to the method that Yue Lao said, wrapped the gas outside the gold mine, and then sent it into the furnace, the gas took on a spherical shape, and the gold ore was quickly melted into a spherical shape suspended in the furnace.

At this moment, Li Ling finally knew what the Dao was when Yue Lao had just smelted the silver essence, the silver essence would be in the shape of a ball, and it turned out to be because of the qi, and if there was gas to wrap the mineral liquid, it would not be splashed around because of excessive energy.

"It can be done." Li Ling took out the gold ore gas that had completely melted into the liquid ore and hung it above the palm of his hand, it was a golden ball liquid.

The golden fluid, the most shining golden light, is concentrated in the center of the sphere, and from the inside to the outside, the gold gradually fades, like a mantle structure.

Li Ling personally manipulated it, and he discovered this subtle change, what Yue Lao flicked with his fingers just now turned out to be those impurities floating on the outside, and those impurities were all gray or white.

"Senior Yue, I seem to understand." Li Ling's eyes stayed on the ball liquid, and he said seriously.

"Yes, go ahead." Yue Lao said solemnly.

Li Ling's eyes stared at the impurities outside the ball fluid, and gently bent his fingers with his fingers, flicking them lightly on the surface, and with a bang, Li Ling's fingers suddenly smoked, and the tip of Li Ling's hand ached, and he was burned.

"This ......" Li Ling looked at the fingers that were constantly smoking, and said in amazement.

"Of course, the ball liquid has been melted at a high temperature of tens of thousands of degrees, even after being taken out of the furnace, the temperature is still four or five thousand degrees, and your fingers are just burned, but it is not a big deal." Yue Lao said very lightly, for Yue Lao, the high temperature of four or five thousand degrees could not even hurt his fur.

It can be seen how high the defense of Yue Lao's own flesh is.

After Li Ling played it once, he didn't dare to play it a second time, and that kind of hot feeling was not only scorched by Li Ling's fingers, but also by Li Ling's will.

"Go on, are you afraid of the pain?" Yue Lao said solemnly.

Li Ling's eyes were lowered, then he raised his head and said, "I have endured a hundred times more pain than this, what is this." ”

Li Ling's fingers popped out quickly, and every time he flicked, his fingers would be burned, and every time he flicked, there would be a heart-piercing pain from the tips of his fingers.

Yue Lao also secretly praised it, after all, no one with the strength of Li Ling had dared to use the gold ore solution with a temperature of four or five thousand to shoot a finger missile.

Therefore, very few people below the county level can learn this skill, and ordinary people take gold mines to the smelter to smelt with tools.

"My technique is so meticulous that I am able to smelt metals that are infinitely close to perfection and infinitely close to 100% purity." Yue Lao is very proud of this skill.

"Infinitely close to 100 percent." Li Ling knew that there was no such thing as 100% purity in this world, and besides, it seemed that the higher the purity, the lower the hardness.

"Yes." Yue Lao said lightly.

"However, according to what I know, the higher the purity of the metal, the lower the hardness, and the practical value is not high." Li Ling has studied physics for a few days, and this most basic knowledge is still knowledgeable.

"What you said is very correct, but you ignore one point, what we need is pure metal with low hardness, the purpose is to compress, the lower the hardness, the easier it is to compress, infinitely compress, and the weapons created can have higher density." Elder Yue said the truth.

Li Ling felt that this point of view was very novel.

"Well, if the density reaches a certain level, it will create a terrible gravitational pull." Li Ling knew that there was such a thing as a neutron star, and it was because the density was too high that it would have a strong attraction.

"There was once a caster who forged a divine weapon, and as soon as that divine weapon came out, it had an oppressive force equivalent to the strength of the Imperial Domain, and this is the real foundry." Yue Lao's eyes also shone with incomparable excitement when he talked about the foundry, as if it was a competitor he respected very much.

"Is it the result of condensation?" Li Ling said.

"Yes, it's the result of condensation, that caster, can condense pure gold the size of his palm into the size of dust particles, just imagine, what a skill." Yue Lao said in admiration.

"It's too exaggerated to condense pure gold the size of a palm into the size of dust particles." Li Ling said in surprise.

"For you now, it may be a bit exaggerated, but I believe that one day you can also reach that level, okay, this is the smelting technique I taught you, it is not too early to see that it is not too early, and it is time for my elder Yue to report to the eldest lady and complete the task." Yue Lao waved his sleeve at the furnace on the ground, and the furnace was included in his sleeve.

Li Ling also put away the piece of pure gold that was gradually cooling in his hand, and prepared to send Yue Lao out of the house, and when he went out, it was indeed evening outside, and when Yue Lao walked to the door, he suddenly stopped, turned back to Li Ling and said: "There is one thing I almost forgot, look at my memory." ”

"What's the matter?" Li Ling looked at Yue Lao Dao blankly.

"I'll have to give you a furnace first." As Yue Lao spoke, he stretched out his fingers, and a copper-colored furnace flew out of the space ring, which looked like a heaven and earth better than the one just now.

"This is a copper-colored furnace, it is considered the lowest level in the furnace, you just start learning, use it first, okay, little brother Li Ling, I'm leaving." After that, Yue Lao's figure was already a hundred meters away, and in the blink of an eye, Yue Lao disappeared into this street at a ghostly speed. (To be continued......)
