...

At the same time, the blazing flames in the bronze melting furnace were extinguished. The furnace opened, and the viscous and hot metal solution rolled out with red flames.

"Congratulations to Master Cui!" Zheng Zhihua stepped forward and congratulated: "This furnace of red fire copper looks excellent in color, and the purity is probably more than 90%.

Cui Cheng frowned, poked out his sword energy, and carefully examined it.

"The purity of this red fire copper is a little less than 90%. If you hadn't come in and disturbed me just now, I'm afraid it would have been done this time." Cui Cheng's tone was not kind and showed no mercy.

Zheng Zhihua didn't think it was at all and said apologetically: "I'm really sorry, I don't know that Master Cui's smelting sword material is at such a critical moment. This is indeed my fault. Please forgive me."

Ou Chuyang thought to himself: Cui Chengyi is really awesome. Zheng Zhihua is the boss. He is just the supervisor in charge of smelting. Logically speaking, it should be lower, but his attitude seems to be completely reversed. However, management talents and technical talents often look like this, which is not very bizarre.

Cui Chengyi nodded casually, expressed his acceptance of the apology, and then ordered his apprentices to help.

Zheng Zhihua took the opportunity to introduce: "Master Cui, this is Master Ou Chuyang Ou who has recently joined our Tiangong Pavilion."

"Yes." Cui Chengyi glanced at Ou Chuyang indifferently, without any expression, and looked extremely arrogant.

Although Ou Chuyang was unhappy, he was still patient and greeted Cui Cheng again, and then asked humbly: "Master Cui's smelting technique has opened my eyes. I wonder if I can give me some advice."

Cui Chengyi said: "Using sword energy to activate fire is a trick that only smelting masters need to master. You are still too far away."

"Master Cui, Ou Chuyang has defeated the smelting master Qiu Shaohui." Hong Kaishan said from the side.

"I know that bet against that time." Cui Chengyi said proudly: "Do you think that defeating the smelter master in terms of the purity of the two sword materials, Yunbian and Wugang, means you are a smelter master?"

"This... I don't mean that." Hong Kaishan said embarrassedly: "Of course I know that meeting the standards of a master of smelting is to be able to smel out a complete set of sword materials needed for a famous tool. But since Master Ou can improve the purity of Yunbian and Wugang to exceed the level of a master of smelting, maybe..."

"Hmph!" Cui Chengyi snorted coldly, "Being superior to Qiu Shaohui in the second-level sword materials such as Yunbian and Wugang can only show that he has his own unique features in the smelting of these two sword materials, that's all."

Cui Cheng paused and looked at Ou Chuyang, "Qiu Shaohui has no talent in the Sword Sect, and it is a miracle that he can reach the smelting master. The threshold requirement of the Sword Sect talent does not mean that the smelting master does not need the Sword Sect talent. Smelting masters, smelting masters, are a huge difference in one word. Do you think that if you smelting cloud steel better than Qiu Shaohui, you can ignore the smelting masters in the world?"

Ou Chuyang was secretly shocked.

It seems that what Master Duan said before that smelters do not need sword sects, but only for the smelter level. If you want to reach the level of smelter masters, it is probably even more difficult without sword energy as an auxiliary.

Cui Chengyi was right. Although the smelter and the smelter master were only one word different, they were actually separated by an insurmountable gap.

In modern society, the word "teacher" often represents a certain profession title. For example: doctor, technician, architect, engineer, pharmacist, etc. However, those who can afford the word "master" are all leaders in their respective fields and powerful people standing at the top of the pyramid.

Judging from Cui Chengyi's tone, Qiu Shaohui is only afraid that he is at the lowest level among smelting masters, and there should be a very big gap compared to Cui Chengyi.

Hong Kaishan continued: "Master Cui is so serious. We have no disrespect to the smelting master. We just think that Master Ou is extremely talented and skilled, so he should be promoted to the smelting master soon."

"Let's talk about it when he can melt the third-level building materials." Cui Chengyi said with a sense of superiority: "Do you think melting the third-level sword material is as easy and casual as the second-level sword material?"

"This... I haven't tried to melt the third-level sword material yet." Li Zhiqi took the opportunity to ask for advice. "I wonder what's special about melting the third-level sword material? I would like to ask Master Cui for advice."

"Okay, since everyone is here today, I will say a few more words." Cui Chengyi knew that it would be difficult to convince the public without taking some real skills at this time. "There is a very big difference between the second-level sword material and the second-level sword material. The most important thing in smelting the second-level building material is the temperature that can be generated by the secret fuel. As long as the temperature is high enough, it will be almost the same. It is not very particular about the separation and purification of the sword material."

Ou Chuyang and three other smelters listened carefully.

"But the third-level sword material is very different. The composition of each third-level sword material is different. The methods of separation of impurities and purification are also completely different. Let me give you an example. For example, if the meteorite impurities with a specific gravity of more than half of the ore of Xingyu Steel cannot be separated without a special formula."

"For example, blood-silver silver is easy to melt, but it is difficult to preserve blood-silver essence; the real gold of the gold body needs to remove pure gold as an impurity, which is extremely difficult. Therefore, the smelting of almost every third-level sword material requires a special formula corresponding to it, otherwise the purity will not meet the requirements at all."

"Furthermore, stimulating the sword energy to activate the fire is also a technique that an excellent smelting master needs to master. But only by reaching the sword sect or above can you stimulate the sword energy with your hands. Do you understand?" Cui Chengyi looked at Ou Chuyang deeply after saying that.

"So that's it." Ou Chuyang and the other three nodded repeatedly.

Cui Chengyi's words gave Ou Chuyang a preliminary specific understanding of the smelting master, and he felt that a brand new world was unfolding in front of him. It was indeed not a simple thing to become a master. He actually needed to reach the level of the Sword Sect above. He was indeed a little far away...

"Listen to your words is better than reading ten years of books." Ou Chuyang bowed respectfully and said, "In the future, please give me more advice and support."

"I can't talk about advice, and I dare not support me. Master Ou is young and has such achievements. I guess he is a famous teacher. Why ask for advice from a bad old man like me?" Cui Cheng said that, and turned around and left, leaving Ou Chuyang and others in place, unable to speak.

After Cui Cheng left, Hong Kaishan explained in a low voice: "Master Cui and Qiu Shaohui are brothers. Last time you defeated Qiu Shaohui, he also felt dull."
