"It seems...... It doesn't seem to have been cleaned up of the impurities! Zhang Meng, who had been paying attention to Ling Li's every move, hesitated slightly, but still replied.

"Well, that's the second question we're going to talk about, which is to really analyze all the properties of the ore. Almost all materials contain impurities of a certain composition, in this world, completely pure materials are almost impossible to exist, but the impurities contained in the ore are not all harmful, there are many beneficial ingredients, if properly controlled, it can increase some characteristics of the material. This requires us to be able to understand all the mineral components contained in an ore in a very detailed way, to remove harmful impurities and retain what is beneficial. In fact, it takes a lot of energy to completely purify a material, especially in the final process. In fact, if we can fully understand the structure of the ore, understand the material composition contained in it, in the refining process, there is no need to be so time-consuming and laborious, as long as the harmful components are eliminated, and the beneficial things are retained, we can save more than half of the effort, we pursue purity in smelting, but if we overemphasize this point, it is too much, it is a waste of effort. ”

Ling Li's words suddenly made everyone suddenly realize that the real masters saved time and effort in the process of refining, not because they had a high purification ability, but because they had a better understanding of the composition of minerals than ordinary people.

Every time Ling Li invests in a material, he will analyze the composition and properties of this material for everyone, mainly the analysis of impurities is much more detailed than in the books, most of these are from the summary of the experience of craftsmen and old monsters of Aoki, but there are also some from the material analysis methods on the earth, which they do not have.

Later, everyone has understood that everyone's daily refining is actually making alloys, and the various materials added are actually the proportions of the components of various alloys.

As for the specific formula, Ling Li only said a dozen kinds, and the addition ratio of all materials is not necessarily fixed, which requires everyone to continue to try in the future. The true meaning and greatest pleasure of refining is to create, not to mechanically repeat the experience of those who have gone before us.

Everyone listened as if they were drunk, Ling Li seemed to have opened a new road of refining in front of them, only the protagonists of this refining, Zhu Xiaoxiao and a few girls seemed to understand it, looking at the appearance of other people seemed to be amazing, but they probably understood what Ling Li said.

Time passed quickly, and Ling Li took out the Qinghong steel he had mixed and threw it into the large mass of molten metal that had been completely melted in the furnace. As the green rainbow steel melted, his technique changed, and the whole solution began to stir and rotate violently, gradually mixing evenly, and the surface of the solution was instead glowing with a strange pale blue light.

The Yuan Force output in his hand became violent, and the frequency of the wave of his hands instantly increased several times, and the molten liquid with a blue glow on the surface floated up from the furnace and spun sharply in mid-air.

"Go!" With a loud roar, the molten liquid flowed straight down, smoothly pouring into the sword mold prepared in advance.

"You'll take care of the rest!" Ling Li said to Liang Xiaotian, the clothes on his upper body were almost all soaked at this time, and he was sweating profusely, this refining work was indeed not an easy task.

Liang Xiaotian is indeed a good iron striker, Ling Li just took a shower and changed his clothes, and a light and spiritual long sword with a smooth shape and a blue and red light was molded.

However, during the construction process, Zhu Xiaoxiao kept pointing fingers on the side, which almost collapsed.

"Here, well, a little more prominent, to make an arc...... Here, it should be thinner so that it looks prettier...... There is also the tip of the sword, the triangular one is too ugly, not beautiful at all, why do you have no aesthetic concept at all, you should learn painting from time to time, this will help improve your aesthetic vision......"

In the end, Liang Xiaotian couldn't stand the noise and went on strike......

It's no wonder that those refining masters absolutely don't allow women to be present when building weapons, it's really too noisy!

Ling Li pointed to the sword embryo that was thrown aside by Liang Xiaotian and said to Zhang Meng, "Throw it into the stove in the house!" ”

Zhu Xiaoxiao jumped up, "What do you want to do?!" ”

Ling Li was angry and funny, "Ke Lingtu, stupid! It's not for you to throw it! He glared at the little girl viciously.

Zhu Xiaoxiao pouted and wanted to cry, but she didn't want to, so she held back her tears and swirled in her eyes.

Ling Li stopped looking at her, entered the refining room, and closed the door directly.

He was afraid that under Zhu Xiaoxiao's trouble, he would not even be able to engrave the Source Spirit Array in the end.

After thinking for a while, he immediately took out the red sword embryo from the furnace and began to carve a kind of ice attribute spirit diagram.

After carving the spirit map, Ling Li vaguely heard a slight sobbing sound coming from outside the door, so he opened the door and said to Zhu Xiaodao: "It's basically almost done, what are you crying about?" ”

"Look at ...... Is that for girls? It's ugly to death! Zhu Xiaoxiao was still sobbing.

Ling Li took a closer look at the sword body, and had to say that Liang Xiaotian's aesthetics did have some problems, although it didn't affect the overall performance, but it did look a little too rough in appearance, "Okay, it's not a big problem, I'll change it carefully for you!" So he sat back down in front of the iron case, and put the sword back in the furnace to heat it.

At this time, Zhu Xiaoxiao watched with wide eyes as Ling Li picked up the small hammer and kept knocking on the surface of the sword body, but this time he didn't dare to talk nonsense anymore.

Soon, a layer of fine scales appeared on the surface of the sword body, blue and red, like a layer of waves, and the tip of the sword also made Ling Li modify it a little more rounded, Ling Li turned out a piece of bright silver sword handle in the storage ring and put it on, and then used the wrong knife and the abrasive cloth to polish it finely.

"I'm satisfied." Ling Li handed the long sword to Zhu Xiaoxiao's hand, "This sword doesn't need to be sharpened anymore, otherwise it will hurt the sword body, but it will lose the sharpness of the ice source qi."

Zhu Xiaoxiao looked at the sword body with light in his eyes, took the long sword, and observed it carefully, and seemed to be very satisfied. However, she soon whispered again: "Ling Li, there is still a place that needs help......

Ling Li's brows suddenly furrowed, "The transformation has to be reheated, which is a bit troublesome." ”

"No, it's just to help carve a few words on the sword......" Zhu Xiao whispered like a mosquito and a fly, looking pitiful.

Ling Li couldn't bear it, "Oh, carve what?" ”

"This side is engraved with 'Qing Yao', and that side is engraved with 'Lingyun'." Zhu Xiaoxiao smiled, and her face became really fast.

It was not easy to carve words on the surface of Qinghong Steel, Ling Li picked up the diamond chisel and beat it for a while, which fulfilled Zhu Xiaoxiao's wish......
