It's no wonder that the Miyanishi clan can be famous for their forging skills, and it turns out that there are such treasures. Ling Chuxi knew that even if he had learned their forging technique, it would probably be useless if he didn't have lava fire crystals, but he didn't bother to think about it now, and watched intently at the movements of Gongxi's mad sword.

"The forging technique of the Gongxi clan is divided into three steps, the first step is smelting, the second step is forging, and the third step is casting spirits, you pay attention to it!" Miyanishi's mad knife destroyed the true qi, and the lava fire in his hand became brighter and brighter, like a burning flame, beating in the palm of Miyanishi's madness. The high temperature that came from the body made Ling Chuxi feel hot on his face, and he subconsciously took a step back, but Gongxi Crazy Knife seemed to be unaware, and his whole body was concentrated on controlling his true qi. I have to say that the Miyanishi Crazy Knife at this moment is completely different from the fierce appearance before.

A wave of red fire leaped out of his palm, scurrying towards the barely formed sword. Under the high temperature, the iron crystal flashed with a cold brilliance unique to metal, and the waves of fire followed the blade all the way to the blade, and at the end, completely wrapped the tip of the knife.

"Now it's forging." Gong Xi's mad knife drank in a deep voice, destroying the true qi with all his might. The flames took on a faint blue color, and the tip of the sword also turned red, and then it took on a silver-like crystal color. Under the high-temperature smelting of lava and fire crystals and the squeezing of true qi, the sword became even sharper and sharper.

Gongxi stopped violently, and took out an ice-like spar from his arms, under the destruction of true qi, a cold current came out of the body, "Huh", the tip of the knife cooled down instantly, flashing a heart-piercing cold, and the surface was as bright as a mirror as if it had been carefully polished.

This time, Ling Chuxi didn't ask much, this spar must be a strange treasure such as cold jade ice crystal, although it is also very rare, but it is much more common than lava fire crystal.

Only then did Ling Chuxi realize how wonderful the forging technique of the Gongxi clan was. The usual forging technique is to first melt and quench with furnace fire, and refine it to remove metal impurities, and some legendary forging masters even use the earth fire cold spring to forge, but no matter how it is tempered, the weapons forged in this way always have impurities.

And the forging technique of the Gongxi clan, borrowing lava fire crystals and true qi, its effect can almost be compared with the aura refining of the Cangyuan Sword Spirit, if you only look at that section of the blade, its quality is definitely not inferior to the Falling Dust Sword that has been tempered by the Heavenly Thunder. It is not difficult to imagine how powerful this knife would be if it had been fully forged.

However, obviously, the consumption of true qi by this forging method is also terrifying, and it is only a section of the tip of the knife, and the Miyanai Crazy Knife is already tired and lying on the ground, sticking out his tongue and panting heavily, but his eyes are full of joy.

"See, this is the forging thaumaturgy of our Gongxi clan, even in the ancient flood time, no forging master can compare with my Gongxi clan." Miyanishi's mad knife relieved his breath and began to get angry again.

"You're tired like this with just the tip of the knife, so how long does it take to completely forge the Eight Desolations Battle Knife?" Ling Chuxi asked. The forging technique of the Miyanishi clan is wonderful, but it is also a little too strenuous. She couldn't help but wonder what would happen if it were her. She also wanted to learn the forging technique as soon as possible, and then re-temper the Falling Dust Sword as soon as possible.
