"Red gold copper, flowing flame iron, yunying ore mother ......" Cheng Daonan selected more than a dozen kinds of ores, most of these ores are very ordinary, and it is not how superb his skills are, and he can use the most ordinary ores to create high-quality products. The main reason is that this assessment can only provide these, and there is no way to do it.

The flames are getting smaller, but the temperature is getting hotter. The pieces of ore were burned red, and the solid layer of stone on the outside gradually fell off.

Cheng Daonan's iron tongs probed and grabbed a piece of red gold and copper. The red gold and copper ore smashed on the desk, sparks splashed everywhere, and the temperature was extremely high. And he held a sledgehammer in his right hand, and the muscles in his arm tensed, and he smashed it down in an instant.

Red gold and copper are the softest, so if you want to quench the impurities in it, you need to use great force. "Bang. With a hammer down, the whole iron table trembled, and the red gold and copper turned into a thin discus.

"Bang bang bang. "The pincers flew, and the red gold and copper kept changing shape under the hammer. Soon, a large number of impurities were beaten out, and the whole piece of red gold and copper was smaller.

"Boom. "Iron tongs clamped the copper and plunged it into the coal-fire. Then, a piece of micion ore mother was clamped, and red gold copper is different, the texture of the corn ore mother is extremely brittle, if the force is too strong, it will collapse into powder directly, but the force is not enough, there is no way to remove the impurities.

"Dangdang. "Every time the hammer is struck, there is a trembling force to strike, so that, as soon as the hammer goes down, there are three crashing sounds, and when the hammer is thrown faster, the sound is like raindrops, extremely dense.

Flowing flame iron is the least likely to melt, so Seido Minami puts it at the end to forge it. "Whew. "As soon as the flame iron is baked. With a path of flames, it burst out in all directions. Forge this ore. It was extremely difficult for all outer disciples. Because the temperature above is too hot. Once it falls on the skin, it can burn a large hole directly into the body.

The speed of quenching in Chengdaonan was extremely fast, but Rao was like this, and it was only after half an hour that these ores were quenched one by one.

He reached out, and several pieces of metal jumped out of the stove and landed on the desk. "When. Yunying Mine Mother was smashed down by a hammer and immediately sank for a few minutes. Because of the hard texture of the corn ore mother, it is most suitable as a sword blade.

Then. The red gold copper is encased in the mother mine. This red gold and copper has the best toughness, which can be used as a sword spine, which can make the long sword not easy to break.

Over time, a long strip of about three feet was forged. Cheng Daonan folded in the middle, and the hammer continued to be forged, and the two pieces of metal were slowly glued together with great force.

"Whew. "Continue quenching, let it soften, take advantage of this opportunity. Cheng Daonan forged several other pieces of metal together, and between different metals, some of them repel each other, and some complement each other. To memorize these kinds of changes, it takes not only excellent memory, but also a lot of practice.

Continued to forge for an hour. A long patina strip was formed, with some crimson patterns faintly covering it. Like blood, it looks beautiful and evil. The sword was like a stab into a person's body. These patterns act like a sponge to suck in the body's blood.

"Snort. The long sword poked into the cold water, and a white mist rose out, and the temperature dropped in an instant. The next step is to cut the edge. The cutting edge is different, forging requires different strength, but the cutting edge needs to be even, so that there is no uneven change on the blade, so that the sharpness reaches an extreme.

"Bang bang. Cheng Daonan picked up a rough stone, poured water on it, pressed the long sword rough blank up with both hands, and his hands turned into a phantom, and quickly rubbed it.

"Snort. "Because of the high speed, the temperature of the rough billet becomes extremely high, and it is often necessary to splash water to cool it down. Gradually, a bright color appeared on both sides of the rough blank.

"Change the fine stone. After changing the whetstone, Cheng Daonan's movements began to slow down, smoothing some uneven places. The bright color on the sword body became more and more intense, as if it was the first ray of sunlight in the sky, although it was not blazing, but it contained endless edges.

"Whew. Cheng Daonan raised his long sword and blew lightly on it, and a few drops of water rolled along the blade. "Tick-tock. "A drop of water fell, smashed on the iron filings, and sank into a depression.

"The time has come. The black-clothed deacon pinched his point and announced loudly. When the time comes, no one can continue to forge anymore.

On the desk of Chengdaonan, a long sword with a three-foot-long sword and a simple body lay there quietly. The hilt is also made of metal, with a circle of threads on it, which can be tightly attached to the hand and will not fall off easily. The whole body is patina, only on the blade, there are two silver white, the two are contrasted, which highlights the sharpness and sharpness of this long sword.

Zhu Changqing stepped off the high platform and commented on everyone's swords in turn. He walked to the front of a desk, a young man about his age, but who saluted him respectfully. It's hard to get to the last step, and no one wants to fall short.

"When. Zhu Changqing's fingers flicked on the blade of the sword, making a crisp sound. "The sword body is too long, and the texture is too brittle, and the force is uneven......" There was no expression on his face, and with every comment, the disciple's face became ugly.

"Class C, medium. Zhu Changqing spit out the last few words and walked to the next desk. And that disciple is like ashes, and the third rank means that he will be eliminated, and when he fails in the last level, he will not be reconciled.

"The long sword is thick and heavy, the sword body is broad, although the force is uneven in some subtle places, but the problem is not big, B, medium. Zhu Changqing picked up a long sword that was only two and a half feet long, and his hand was very heavy, almost catching up with the weight of a big sword.

Zhu Changqing commented quickly, although he is narrow-minded, but he can achieve this position, and he still has the ability. Most of the long swords can be seen by just eyesight.

He walked in front of Cheng Daonan, but did not look at the sword, but quietly looked into Cheng Daonan's eyes. "Wait, wait. The corners of his mouth curled, and he slowly said these three words. Ding is the lowest evaluation.

"Elders, are you sure you don't want to take another look?" Cheng Daonan took the long sword in his hand, and with a slight touch of his fingers, a low trembling sound sounded. Tough enough, but not too soft, this sword can already be regarded as a high-quality category.

"You...... Is it worthy?" Zhu Changqing walked to his side, his tone full of disdain and mockery. "You'll find out soon...... Am I worthy or not. He didn't say this, and shook his head slightly.

Cheng Daonan held the long sword in his hand, turned around and left here. (To be continued......)
