When Zhu Cheng saw him stop, his expression was strange, and he immediately became anxious, and hurriedly dragged him away.

When they turned the corner, You Zhukong came back to his senses, and then he found that his palms were in sharp pain, it turned out that he had broken his palms, his eyes were still wet, and it turned out that he was crying.

You Zhukong said in a low voice: "Brother, that female demon just now is my enemy, and I will avenge this sooner or later!"

Zhu Cheng said categorically: "I will accompany you for revenge!!, but don't act rashly now!"

Speaking kung fu, they came to Guan Boss's equipment shop and reported more than a dozen materials and tools needed for forging techniques, including fine iron, heavenly fire ice, iron hammers, fire tongs, eye patches, etc., these things are more ordinary than forging spiritual energy substances, Guan Boss has them all in his shop, and Guan Boss boldly gave them the best varieties.

The two bought materials and tools, didn't dare to stay longer, and hurriedly sneaked back to the campus. Qianqian had already learned the method of refining the spirit knife in the forging technique three times, and cleaned up Qinghong Burning Ding.

As soon as You Zhukong came back, they began to refine, Qianqian explained the method to You Zhukong in detail, Zhu Cheng was not good at this, so he still gave them a helper.

The weapons of this world, unlike ordinary weapons, are mixed with a substance similar to aura metal, which can assist the aura to be emitted and produce huge destructive power.

However, this kind of substance cannot be put too much, and its proportion must be strictly controlled, otherwise the sharpness and solidity of the spirit knife will be greatly reduced.

The best weapons are after repeated forging, not only can the aura be outgoing, but also can sharpen iron like clay, such weapons can be divided into grades, ranging from one to nine grades, each grade is divided into inferior, medium, and superior three grades, there are also some handed down artifacts, there is no grade.

Weapons with grades can only be refined by forging masters, and they have not undergone formal training from forging divisions, so it is extremely difficult to refine weapons with grades, but ordinary weapons can also be sold at a good price, which is their best choice.

Ordinary weapons can also be divided into inferior, medium, and upper grades, and the sales volume in the civilian sector is considerable, but if you want to master the refining of ordinary weapons, you also need to study for two or three years, which is a huge challenge for You Zhukong.

In order to prevent sparks from hurting his body and eyes, he put on a metal shell blindfold, ** on his upper body, and smeared a plant essential oil on his body to prevent burns.

He first put the Heavenly Fire Strange Ice into the refining furnace, and began to heat up for Qinghong Burning Ding, and soon he used his aura to sense the change in temperature, and when he reached the limit, You Zhukong decisively shouted: "Feed!"

Zhu Cheng and Qianqian had already prepared the refined iron aside, and quickly put it into the smelting furnace, melting the refined iron was a long process, You Zhukong continued to use the aura to urge the fire, and gradually the refined iron began to melt, You Zhukong used the aura to drive the refining furnace, and the molten iron began to rotate in the furnace.

Seeing that the heat was suitable, You Zhukong shouted the names of several auxiliary materials, Qianqian knew the forging steps better than him, just waiting for him to send a signal, as soon as the signal came out, Qianqian immediately put the auxiliary materials into the refining furnace.

When the auxiliary materials entered the refining furnace, a puff of black smoke came out of the furnace, and the secret room could not be ventilated, and the smoke was immediately filled, and the three people choked and coughed.

You Zhukong coughed, and immediately his aura was chaotic, and the furnace was chaotic, and he hurriedly poured out the molten iron according to the method in the forging technique, and the furnace was scrapped. The three of them knew that the refining had failed, so they hurriedly rushed out of the secret room and gasped for breath.

"This can't be done! Although there was smoke when forging the aura substance, it was not as big as this time!" Qianqian sighed.

Zhu Cheng sighed: "Although there are vents in the secret passage, the ventilation in the secret room is far from enough, if there is an exhaust pipe that leads directly to the outdoors, it would be good!"

You Zhukong sighed: "This secret passage, we can't dig it out, let's go, find a few wet cloths, and just gag your mouth!"

Zhu Cheng said: "It's better to be like this, we haven't finished exploring the entire secret passage, maybe there is a more suitable secret room for forging, you continue to forge, how about I search the secret passage again?"

You Zhukong and Qianqian nodded in agreement, so the three soldiers split into two ways, You Zhukong and Qianqian forged weapons, and Zhu Cheng was responsible for continuing the search.

This time, Qianqian found a large bucket of water and a dozen wet cloths, covered their mouths and noses, and began to try forging again.

With the first experience, You Zhukong melted the fine iron at a faster speed, and Qianqian assisted him in putting in the accessories, and when the accessories fused with the fine iron, the smoke filled the room again, and they barely managed to hold on with a wet cloth to resist.

After a while, the refined iron fused with the auxiliary materials and turned into stainless steel, the molten iron ran perfectly in the smelting furnace, and all the impurities rose to the top.

These materials are the main materials of the Reiki substance, and Qianqian quickly poured the materials into the refining furnace, which is the most difficult part of the entire forging technique, if the Reiki material cannot be perfectly fused with the molten iron, it will lead to the failure of refining.

You Zhukong had experience in forging spiritual energy substances, and this level was actually very easy. He divided the aura into more than a dozen strands, each controlling different raw materials, and letting them fuse one by one.

Just this one process, if he changed his previous world, it would require at least dozens of complex processes and hundreds of sophisticated equipment to complete, but now with the subtle control of aura, every qiē has become very clumsy.

Fusion to the final stage, You Zhukong once again lost his aura, Qianqian cooperated with him many times, already had a heart, as soon as he showed fatigue, he came behind him, gently hugged him, held his arms, and delivered aura to him.

You Zhukong enjoyed this link very much, when Qianqian hugged him from behind, he could feel Qianqian's soft and firm breasts, a faint grass body fragrance, and soft boneless hands. So You Zhukong deliberately slowed down and tasted more about the basket of roses

In this way, it will help the fusion of the aura substance and the molten iron, and after a while, You Zhukong found that the two had become one and there was no longer any flaw, so he shouted: "Ready to bake!"

Qianqian was also intoxicated by the hug just now, and when she heard him shout, she came back to her senses, and hurriedly blushed, set up the mold, and You Zhukong poured out the molten iron, and soon the molten iron solidified in the mold.

You Zhukong took out the iron tongs, clamped out the solidified iron, and put it on the top of the refining furnace, and Qianqian added a large amount of Tianhuo Qi Ice to the refining furnace, and Qinghong Randing turned into a blue and red color at high temperatures, and they realized that Qinghong Randing really had a bit of a background.

You Zhukong began to forge iron tongs in one hand and hammer in the other, and from time to time sparks splattered, and when they splashed on him, the plant essential oil prevented the sparks from burning his skin, but it still hurt faintly.

Qianqian used the aura to control the firepower on the side, although she was clumsy, but the focus of forging had shifted to tempering, and the requirements for firepower were not high, so she plucked up her aura and just exerted her strength.

After thousands of tempering, the iron becomes more and more refined, and every time You Zhukong smashes down, he will use his soul power to sense the structure and changes of the iron, and the next hammer will be shot down in a targeted manner, which is far more efficient than smashing indiscriminately, a hundred times more efficient.

After an hour, the iron gradually took shape, You Zhukong and Qianqian were very happy, and soon You Zhukong forged the iron into the shape of the spirit knife, and then put it into the potion, with a bang, the spirit knife changed violently in the medicine, and the perfect structure was produced inside, and the potion was stimulated by the high temperature, emitting a pungent water mist.

In a moment, the spirit knife was completely solidified, You Zhukong took out the tools again, polished it, and a spirit knife was finally forged!

You Zhukong and Qianqian hurriedly walked out of the secret room, picked off the wet cloth, gasped for breath, they were really stuffy, You Zhukong brandished this spirit knife, feeling that the tiger was vigorous, Qianqian took out an old weapon she had collected before, slashed each other with both hands, and with a click, the old weapon broke in response

You Zhukong saw it and laughed happily, he took the spirit knife, took it in his hand and waved it repeatedly, and at the same time activated the spiritual energy, pouring the spiritual energy into the knife, and the blade of the spiritual knife immediately emitted a little light, becoming even sharper.

Seeing that there was still time, they built a second one overnight, and this time it was much faster than the first forging due to their skillful operation. By this time, it was already daylight, and the two of them were exhausted, and they all returned to the dormitory to rest.
