Bai Yumei, as a Six Tribulations Scattered Immortal, she is really worried about the strength of the cash cow, not anything else, it refers to the strength of refining weapons, generally speaking, every cultivator, he is a polymath, in addition to the corresponding astronomical and geographical knowledge, there are also refining, alchemy and even qin, chess, calligraphy and painting, these are also a course that a cultivator must know, however, everything is talented, some people are good at killing, and some people are better at saving people, the cash cow may have very good talent and strength in other aspects, but in terms of refining, But it is very worrying, because, like alchemy, refining tools not only require talent, but also need long-term contact, need the support of a powerful sect, and need more and more other things, for example, as far as Bai Yumei's cognition is concerned, a very good furnace is one of the guarantees for refiners to improve their success rate, but this seems to be a cash cow that does not have it!

Fortunately, the requirements of the cash cow are not very complicated, in his opinion, these kinds of things can be practiced into a tool is already quite good, there is no hope to be able to practice into a pick-up, you know, casual steel, star iron and the like are relatively rare, but, that is relative to the secular world, in the cultivation world, although this kind of thing is not garbage, but, a treasure, want to change a mountain of star iron, pay attention, it is a mountain, it is still very easy, at least, if there is a treasure of the magic weapon of the eight characters love white ignorance in front of the face, She will not hesitate to exchange a star iron mine for it, even then, she is also earning, so, can the cash cow do it?!

She had the intention to use the refining room that she used to increase the success rate of the three-point refining tool to the cash cow, but she didn't expect the cash cow to refuse, just asked her for a quiet room, of course, it was not without requirements, this quiet room must be remote, quiet, and strong, and she didn't expect Yao Qianshu to want what kind of Bai Yumei was willing to see and see his refining strength, so she didn't hesitate to give Yao Qianshu a practice room made of wooden fish stone that she didn't usually use, which was located in the back of the courtyard, of course, Bai Yumei is not without conditions, that is, she must watch the whole process of refining, Yao Qianshu agreed without even thinking about it, which made Bai Yumei a little more curious about the cash cow!

Three hundred catties of star iron, one hundred catties of Qinglan stone, and one hundred catties of steel were piled up into three hills near the left side of Yao Qianshu, but because these three things were hard things with fine textures, if they were really true, they were only three piles.

Refining is a very particular thing, there are many things that need to be paid attention to, at least, there are different requirements for the stage of not passing, some people say that refining tools need pure metal and high-grade materials, this is good, but let the real experts hear it, it will definitely mean a smile.

What kind of magic weapon needs what kind of material, the material to which it belongs here is by no means the type of material, but the purity of the material, such as the magic weapon long sword that Yao Qianshu is preparing to refine now, because it needs to have a certain toughness, therefore, the star iron can not be particularly pure, which also needs to retain a certain amount of impurities, of course, these impurities are not soil and sand and the like, but are likely to be other unknown metals, according to Yao Qianshu's simulation in his mind, when the purity of the star iron is purified to more than ninety percent, It will be at its toughest, or rather, it will have been alloyed with other metals in it.

How to control the purity? Of course, it depends on the temperature, and the average refiner, some of them use the three-flavor true fire, and some use a kind of flame, which is like the true flame of the sun, the true flame of Taiyin, the true fire of Taiyi, etc., of course, there is also a large part of the use of earth fire or heavenly fire, such as the earth's core fire in the magma crater, the Nine Heavens Separation Fire collected in a special way after the heavenly thunder splits, and so on! And the cash cow, what is used is not these types of flames, but a slightly weird chaotic soul fire, this kind of flame comes from the soul, the cash cow is now used when refining weapons, and when he cultivates to the peak, it is not impossible to destroy everything with a wave of his hand, because this kind of fire is not a virtual fire or a real fire, but a chaotic fire between the virtual and the real, from a little spiritual seed generated in the chaos before the opening of the world, the cash cow can master, but it is not the credit of the white-robed old man in the head order, but the benefits of his extensive reading of which jade slips were found, and where did they find it by chance, it is with soul refining and heart refining, chaos soul fire is suitable for soul refining, and Taiyi heart fire is suitable for heart refining, and the level of heart refining is lower than that of soul refining, and Yao Qian's book refining techniques are these two!

With a slight wave of her hand, three hundred catties of star iron floated up, and Bai Yumei, who was sitting in the distance, looked at her, from this simple wave of her hand, she could see that the strength of the cash cow was really a few points higher than she guessed, and then Yao Qianshu's actions made her extremely surprised!

I saw a cash cow mouth, and a golden flame came out of his mouth, and instantly wrapped the star iron in it, only to hear the sneering sound endlessly, it didn't take much effort, the original one-foot square star iron block became a red solution the size of the mouth of the sea bowl that emitted a little bit of light, in fact, the cash cow is now completely able to regulate the chaotic soul fire in the meridians in the body, but, in order to avoid shocking the world, he still used the most stupid method, but he didn't expect that even so, It also scared Bai Yumei enough, it turned out that at the moment when this golden flame appeared, Bai Yumei's soul fluctuated greatly, almost shaking her Dao Ji.

Spewed out a mouthful of pure true vitality, wrapping this red solution, Yao Qianshu summoned the Qinglan Stone again, and then used the Chaos Soul Fire to begin to melt, and it didn't take half a pillar of incense time, this Qinglan Stone also turned into a cyan solution, and then, he summoned a hundred steels, the same step, this metal melted into a mass of solution!

This is the first step of refining, called purification, and the second part is fusion, which is actually not simple, because the method, speed, degree, etc. of fusion directly affect the quality of the final product.

But with the guarantee of the Chaos Soul Fire, this step was completed very quickly, after the fusion, it was the billet stage, this stage, in fact, it was the death to convert this mass of solution into the appearance of a magic weapon, this stage was actually the easiest, before the refining began, Yao Qianshu had an idea, therefore, soon, a pale cyan sword appeared in front of Bai Yumei!

Below, it is the stage of spiritual possession, to put it bluntly, it is the restraint formation, this stage, Yao Qianshu took about an hour and a half to complete this work, and there were nine hundred and eighty hundred and ten formations carved in it.

A sword about two and a half feet long and two inches wide is freshly baked, and between the swings, pieces of cyan light and shadow fly with the sword, this sword is called Luoying!
