Chapter 1329 Sword Body Forming

"As for why I did the Iron Can Malaysia, I still did the spark test. Let's talk about it later. Xiang Yu, I will attack you first, don't worry, there is still time."

After saying that, Zhang Yu stopped talking, but continued to start forging the sword edge. Xiang Yu smiled slightly. He was not angry because Zhang Yu reminded him during the game, but instead smiled. Then Xiang Yu chose some bolts, screws, scissors and iron pipes. He opened the grinder, wiped the materials one by one, placed them on the grinder, and conducted spark tests.

Zhang Yuwei's side had been forged and formed. He stood the sword in front of him, but did not touch the ground. Zhang Yuwei knew very well that once the forged steel billet touched the ground, it would react chemically with the substance on the ground, thus generating a layer of impurities on the sword, which greatly affected the strength and sharpness of the sword. Therefore, Zhang Yuwei held the sword in the backhand and stood in front of his chest. He turned his right hand and a bubble appeared in the palm of his right hand. Zhang Yuwei didn't think much about it and directly hit the sword body. He heard "snap~~~~~" White smoke came out of the sword body. When Baiyan passed, the prototype of a straight sword appeared in Zhang Yuwei's hand. Zhang Yuwei made a stance to stab the sword, and his eyes looked from the tail of the sword. Seeing that the sword body was straight and there was no bending at all, he nodded with satisfaction.

"I really didn't expect you to choose water quenching. If you want to quench it, won't it be possible to quench it with oil? You are not afraid that the sword will break if the water quenching."

Xiang Yu, who was still forging U-shaped steel billets, saw that Zhang Yuwei had completed the quenching. He joked, but he was quite summoned in his heart. Although Zhang Yuwei said that there was enough time, don’t worry, but two hours had actually passed. Xiang Yu had to start over because the steel billet broke. Seeing that Zhang Yuwei was almost done, sweat broke out on his forehead, and he was impatient.

"I also want oil quenching, but do you see this? By the way, your forging technique is not learned in modern times. How do you know oil quenching? Did oil quenching be there in the Chu and Han dynasties?"

When Zhang Yu heard Xiang Yu's joke, he was very confused. He was convinced that there was no such thing as oil quenching during the Chu State period. If Xiang Yu had mastered modern forging techniques at that time, I was afraid that Master Xu would have to take him as his teacher. Seeing Zhang Yuwei asking, Xiang Yu said "hum".

"I didn't have that era and now? Yuwei, don't think that you can only browse your phone, will this king be fine?"

"Damn it, didn't you break the case with a flip phone? You actually use a phone?"

The two of them kept spanking their mouths, and their movements did not slow down at all. Zhang Yuwei was constantly polishing the sword body. He wanted to make the sword sharper and lighter, so he had to thin the heavy area. Xiang Yu also completed the production of three steel and began to perform secondary calcination. About a quarter of an hour later, Zhang Yuwei stopped polishing. At this time, his sword body was extremely sharp and shining with silver light. As for the sword body, it was comparable to the sword hanging on the wall. However, Zhang Yuwei was not satisfied with such a sword body. He stretched out his index finger, used the power of the golden element and blessed a trace of holy Taoist Tianshen Yan, and began to portray fine lines on the sword body.

Xiang Yu took out the calcined steel billet and forged it again. The first time he dropped the hammer, Xiang Yu felt that the feel was very different. It was obvious that the steel billet was much stronger this time than before, so he simply did not restrain his strength. In order to speed up, Xiang Yu frantically swung the hammer forging. For a moment, the sound of "dong, dong" resounded throughout the forging room.

Just as Zhang Yuwei finished carving the fine lines, Xiang Yu also ended the forging. He looked at his newly forged sword body and nodded to express his satisfaction. Then Xiang Yu directly penetrated the billet deep into the bucket. Suddenly, thick white smoke radiated from the bucket. With the sound of "hiss", Xiang Yu pulled out his billet. He saw that his sword body had been formed. Like Zhang Yuwei, Xiang Yu's sword body did not bend at all. The three steels completely formed a perfect billet without a trace of faults under his construction.

Seeing that his sword was basically completed, Xiang Yu looked at Zhang Yuwei with confidence, and directly Zhang Yuwei put the fine-grained sword into a bucket. There was a strange liquid in the bucket. Xiang Yu found that he also had this bucket, but he didn't know what the bucket was for. Therefore, Xiang Yu did not intend to put his sword into the bucket. He began to polish his sword body on the grinder to make it sharper and lighter.

After waiting for five minutes, Zhang Yuwei took out the sword in the bucket. He saw that the sword body had lost its polished glow and no longer had silver light. The surface was a little dim. Faced with such a situation, Zhang Yuwei was not only not panicked, but was very satisfied. He put the sword body and began to choose wood to build handguards.

"Is it actually sour? I didn't expect it to be so meticulous."

Nangong Xian looked at Zhang Yuwei's operation and sighed repeatedly. Although Zhang Yuwei did not use the forging technique in the universe, in terms of the forging technique on earth, Nangong Xian felt that Zhang Yuwei's level could be said to be extremely exquisite and exaggerated. During the forging process, he kept paying attention to the sword bodies of the two. The patterns and spacings of Zhang Yuwei's carved were the same, which surprised Nangong Xian very much. If he had not seen it with his own eyes, he would not even believe that such a sword was artificial.

"Elder, what is acid soak?"

Hearing Nangong Xian’s words to himself, some students raised their own questions. Seeing the students looking at him with a gaze, Nangong Xian smiled. He knew a lot about sour soda. He pointed to the bucket containing the strange liquid, and Nangong Xian explained.

"Acid soaking means soaking the created sword body in an acid solution. The principle is that steel with different properties undergoes oxidation to varying degrees after reacting with the same chemical reagent, resulting in color difference to show patterns, which can make the sword more beautiful."

"So that's it. I didn't expect that there would be such an effect. I've never heard of it."

Seeing many students lamenting Zhang Yuwei's forging technique, Nangong Xian continued to explain.

"It's normal that I haven't learned it. Now I rarely use acid soaking. I use other methods to deal with the sword body. However, the forging room retains the props for acid soaking. I just didn't expect that he would use it. Who knows his name?"

A knife forging competition made Nangong Xian very curious about Zhang Yuwei. At the same time, he also began to pay attention to Zhang Yuwei from the bottom of his heart. After asking about Zhang Yuwei's name, a student immediately responded.

"Elder, I know that he is a newly promoted student of Tianzi Academy, named Zhang Yuwei, from Earth, and the other one is like him, named Xiang Yu."

"Hiss, so that's it. He is the Emperor's Spirit Root!"

When Nangong suddenly realized the words Zhang Yuwei, he saw Zhang Yuwei's eyes changing for a moment.
