Since he thought of the method of pouring the mold, Beifeng Yang immediately took action, preparing to subvert the tempering method.

Beifeng Yang's current control of Shuangyang Guijing can be said to be perfect, he probed down with both hands, and then lifted it up, a misty element was extracted, his hands were closed, the elements began to compress and fuse, and in just a while, a colorless and transparent substance was generated. Then according to the shape of the sword shell to stretch the structure to make a hollow sword shell, the hollow sword shell is composed of two halves of the right and right symmetry, can be separated, can also be merged, the north wind Yang began to construct the inner surface of the separated sword shell to construct the magic circle concave, the first is to construct the spiritual power circuit circle, this spiritual circuit can allow the spiritual energy injected into the spirit sword to return to the user's body, and the second is to construct the spirit of the spirit circle, so that the spirit sword and the user's mind can communicate. Originally, Qingrui only asked to engrave these two magic circles, but Beifeng Yang thought about it, and finally carved a solid magic circle in the Fu Array Heavenly Scripture.

After the two circles were burned, the hollow sword shell, that is, the sword mold, was made, leaving a filling opening at the hilt of the sword shell.

Beifeng Yang took out the Wuhuang Ding, put it on the ground, and silently recited in his heart, the Wuhuang Ding became bigger, and the Wuhuang Ding became bigger. The Wuhuang Ding immediately grew in size until it was as tall as Elder Qingrui's Refining Spirit Ding.

Elder Qingrui was also quite surprised to see the size of the Wuhuang Ding raised by the north wind, but there were many items that could be scaled in the Immortal Cultivation Realm, and he didn't think it was too unusual, but he also knew that this Ding must be extraordinary.

"The injuries on your hands are all healed, you still need to practice more hammer techniques, and you need to pay attention to the direction, direction, and strength of the hammer. He glanced at Beifeng Yang and said. He took out the saber that had been knocked off the edge by Beifeng Yang and handed it to Beifeng Yang.

"You refine it again! Recently, there are many refining tasks, and the time is tight, although Dao Liang, this kid, has mastered the refining heat well, but the speed is too slow, and you can't count on him, although you are a beginner, the speed of production is actually faster than him, but there are too many wastes. After he finished speaking, he went back to work.

Beifeng Yang couldn't help but scolded: "Okay, this old man actually treats himself as a laborer, hmph, I really don't want to stay here, I take a hammer and beat it all day long, I feel like a blacksmith, this is not my favorite style, today I will let you see what is the Dafa of integrated forming and casting!"

Beifeng Yang threw the waste sword into the Wuhuang Ding, stretched out his palm, and with a stabbing sound, a blue flame rose from his palm. Elder Qingrui turned his head when he heard the sound, and just saw the blue flame, he couldn't believe it in his heart, this is a flame color that he can't reach, the flame color in his palm is arranged in no order of red, orange, gold, white and blue, the temperature is from low to high, he can rise to light blue at most, and the pure blue fireworks can't be generated by himself.

Beifeng Yang hit the blue flame into the Wuhuang Ding, the sword in the Wuhuang Ding quickly melted, this sword has been purified before, so there are very few impurities, but he still saw a small piece of dark yellow impurities, about to clear it, his mind just moved, but saw that the impurities have been cleaned up, without a trace, Beifeng Yang thought, could it be that this Wuhuang Ding has been psychic, understand the master's mind, this is simply great.

When it comes to alchemy and refining, in fact, the most tedious thing is to clean up impurities and purify materials, which often requires refiners to use their divine sense to pull out impurities, which is very draining, if Wuhuang Ding can help remove impurities, it will be much easier. And using his own divine sense to remove impurities is not as clean as Wuhuangding's treatment.

Then Beifeng Yang verified his conjecture, as long as he thought of which piece of impurities to remove, Wu Huangding immediately did it for him, it was simply amazing.

Beifeng Yang wrapped the purified melt with spiritual power and poured it into the casting hole at the hilt of the hollow sword shell, just filling the entire mold, and then injected spiritual power until the spiritual power was saturated.

It was too late, it was too fast, and Beifeng Yang quickly picked up the sword shell and sank it into the ice pool next to it, but when he heard a long "boom", the quenching of the sword was completed. The north wind threw a few ice picks into the ice pool to cool down.

After a while, Beifeng Yang separated the sword shell and took out the saber inside, but saw that the sword body was as smooth as autumn water, emitting a bright cold light. It's a lot better than the previous Tempered Sword. Moreover, the slightly raised formation patterns on the sword body are even more uniform and detailed, and the spiritual light flickers, injecting a trace of spiritual power into the sword formation, and the spiritual light is even stronger.

After refining all the previous waste swords, and refining them with new materials, because the mold can be reused, the time for Beifeng Yang to refine a saber is greatly shortened, and each time it is three materials thrown together, and before he knows it, all the materials that Elder Qingrui put on the ground like a hill are used up! On the shelf in front of Beifeng Yang are neatly placed thirty swords.

Elder Qingrui hurriedly refined a saber, turned around and wanted to get the materials, but he didn't expect the pile of materials behind him to disappear, and turned his head to look at the north wind Yang but saw many swords neatly placed on the shelf in front of him. Qingrui was very strange, and walked over and said, "Feng Yang, where are those materials?"

Beifeng Yang was refining the last saber and said, "Elder Hui, all the materials have been refined into swords. Uh, no, there's one last one in Dingzhong!".

Elder Qingrui couldn't believe it, there were a full thirty swords on this shelf.

The material impurities in the Wuhuang Ding have been cleared, Beifeng Yang used spiritual power to wrap the melt into the sword mold, just full, and then Beifeng Yang continuously injected the spiritual power in the body into it, and finally put the sword mold and the sword together into the ice pool to quench the sword, only to hear a long sound of "boom", the quenching of the sword was completed, and the last saber refining was completed.

Elder Qingrui stood aside and read it seriously, it was simply incredible, it was obvious that this casting method was far more efficient than the method he had tempered. But when he thought about it, fast is fast, and he doesn't know what the quality is. So he said: "Feng Yang, your method is very efficient, especially suitable for batch refining, it is estimated that the grade must not be very good, it is better for you and me to use our own refining swords to fight hard." ”

Elder Qingrui returned to his weapon rack, drew his sword that had been tempered at the end, and walked towards the north wind.

Beifeng Yang casually took a cast saber from the weapon rack and walked towards Elder Qingrui.

The swords in the hands of the two slashed together fiercely, only to hear the sound of "p-

Oh my God, he has been refining weapons for 200 years, and he is not as good as this teenage Beifeng Yang, he can't compare with him in terms of quantity, and he can't compare with him in terms of quality, he is simply a complete failure! This son is really a talent! No, he is really a genius in refining weapons, no, he is really a demon!

"Bang dang!" The broken sword fell to the ground, and Elder Qingrui also sat down on the ground, his expression was sluggish, and the whole person seemed to be dozens of years old for a moment, he trembled and stretched out his hand, pointed to the entrance of the cave, and said: "You go, thank you for helping me refine the sword, I really have no shame to guide you in refining the weapon anymore." ”

"Thank you Elder Qing for your care during this time, I'm leaving, and the sword model will be given to the elder as a souvenir. ”

The north wind bowed to Qingrui, looked around, and walked away.

Looking at the north wind and walking away, Elder Qingrui stood up, took the sword refined by the north wind and looked at it carefully, the appearance was smooth and bright, like a pool of autumn water, it was perfect, and tried to inject a trace of spiritual power, the three magic circles on the sword body emitted a shining light, carefully distinguished, two spirit patterns faintly appeared on the sword body, one more spirit pattern than the one he refined, a medium-grade spiritual weapon! Such an ordinary material refines a medium-grade spiritual weapon! Isn't this material all a low-grade spiritual weapon?

After refining weapons for so many years, Qingrui has refined medium-grade spiritual weapons, and even high-grade spiritual weapons, but they are all high-quality materials, and even genius earth treasures.

It seems that the disciples who have recently advanced to the inner gate are blessed!
