Du Feng engaged in forging by himself, because there was no suitable furnace, so he would use the Medicine King Ding as a furnace. Although the temperature is very high, it is somewhat inconvenient to take the molten iron. The sect's forge is different, with furnaces, forging tables, forging hammers, and fire sources.

Mountain fire is different from lung fire, which uses the heat accumulated in the magma layer underground. Make an opening in the ground and draw the heat up.

And the fire of the mountain is the heat in the mountain. This heat did not come from the ground, but from the movement of the mountain itself and the influence of the fire attribute spirit veins. The heat surged through a gap in the mountain, eventually breaking through a gap. It is collected by the formation and can be used for forging.

Of course, this collection process still requires some fairy stones. Use immortal stones to replenish the Yuan Force of the formation, and then you can introduce the mountain fire into the furnace well.

"Hall Master Du, you are busy first, we have retired. ”

Du Feng's face is still quite big, and he dominates the forge alone. A bunch of disciples who were working inside all honestly withdrew. Generally speaking, as long as it is not the door master, the deputy door master, and the four elders who want to use the forge workshop, he still has priority as the hall master.

"Well, I'll be bothering you for the next few days. ”

Du Feng did not use the forge temporarily this time, but used it for several days in a row. Therefore, in the next few days, not only would the other disciples not be able to use it, but someone would also cause someone to guard the door for him outside and block others.

In this way, the others retreated, and Du Feng walked to the furnace alone. He looked at the formation below, then observed the furnace, and then stuffed a few high-grade immortal stones into the corresponding positions. If you want to make good use of the fire of the mountains, immortal stones are definitely indispensable.

It's a pity that he doesn't have second-order immortal stones, otherwise in the process of forging, there would be no need to add immortal stones repeatedly. Now I use high-grade immortal stones in the first order, and almost every time I finish forging a flying sword, I have to add immortal stones once, and I have to add many pieces at a time.

Tut-tut...... Although I made a small profit at the auction, I still didn't have enough money to spend. Du Feng had already thought about it, and when he had the opportunity to go to the immortal city of the Southern Heaven Realm, he would earn another sum of money to spend. It's best to find a place to exchange for some second-order immortal stones.

The exchange ratio of second-order low-grade immortal stones and first-order high-grade immortal stones is also one to one hundred, but this is the official ratio, and if you exchange it from private channels, I am afraid that you will lose some.

After the immortal stone is inlaid, the furnace does not immediately catch fire. Instead, he waited for a while, and first the formation was activated. Then, under the attraction of the formation, the fire energy in the mountain range was constantly used. After accumulating to a certain extent, it poured into the furnace.

"Whew...... Whew......"

Behind the mountain range was really fierce enough, whirring in the hearth like a giant beast was spewing gas.

"Good, good stove!"

Du Feng was in a good mood because he could play to his heart's content. He took out a pile of ore, threw it into the hearth, and closed the thick iron door.

It is really worthy of the fire of the mountains, and it is really worthy of the melting pot of the sect, which is really different from the small melting pot of individuals. In just a few moments, the ore was melted into molten iron. But Du Feng was not in a hurry to pour out the molten iron, but let it continue to calcinate inside.

After a few more moments, yellowish soot was seen coming out of the vent at the top of the furnace. That's right, that's what you want. When the temperature is high enough, some impurities in the ore will be vaporized and then volatilized. As a result, the quality of the weapon will be higher.

After the smoke and dust no longer appeared, Du Feng opened the drainage groove to let the molten iron stay, and slipped into the mold of the sword embryo impartially. When the sword embryo was in a semi-soft state, Du Feng clamped it onto the forging table, and it was the turn of the hammer to start clanging.

"I didn't expect Hall Master Du to have this hand, I knew that we should ask him for advice. ”

"Who says it's not, you listen to the sound of this beating, and you are a master when you hear this sense of rhythm. ”

Du Feng's hammering is not a random knock, forging this kind of thing is skillful. Each hammer falls, what force and angle, and how long it stays on the sword embryo are all particular. Not only must there be regularity but also feeling, which comes from the intuition of the forger, and to put it bluntly, talent.

"It's a pity, the master of the Du Hall is opening the Sealing Array Hall, if it is the Forging Hall, let's ......"

Several disciples who like to engage in forging are very sorry, because Du Feng's new opening is a sealed array hall, so the group of people who can become inner disciples are also disciples who like formations. And only a small part of those who like to engage in forging are inner disciples, and the rest are outer disciples.

If Du Feng opened a forging hall, they might also become inner disciples because of this, and they would enjoy different treatment, which could be regarded as having a skill.

"Why don't we go and apply to the deputy head. ”

"Yes, I think so too, let's go together and call all the junior brothers and sisters. ”

Du Feng was concentrating on forging in the house, not knowing that the disciples outside were beating his idea. There were already many disciples in a sealed array hall, and they still wanted Du Feng to open another forging hall. The difference between the forging workshop and the forging hall is the difference between the outer disciples and the inner disciples.

This kind of thing is generally handled by the deputy master surnamed Jin. He's younger, he doesn't need much retreat, he's the best at dealing with this kind of thing.

"Let's all go back, I'll think about it. ”

A group of disciples found the deputy master with great interest, but they were sent back by the deputy master with a few words. The reason why this is so simple is simple. Because Elder Taishang already knew about Du Feng's forging skills, and was discussing whether to open a forging hall.

As long as the Supreme Elders agree, the Forge Hall will definitely be able to open. If a few of them don't agree, it's useless for the deputy door master to open it again. So he simply asked the petitioning disciples to go back first and wait for the news to be announced.

"Since the establishment of our Yuxian Sect, there has never been a situation where one person is in charge of two halls. ”

The Grand Elder Taishang was rather old-fashioned and felt that this matter would not work. Although Du Feng's formation and forging ability are good, he is a person after all. It's enough for one person to manage one Sealing Array Hall, and it is not possible to open another Forging Hall at the same time.

In fact, there are still masters in the Feather Immortal Sect Forging Sect, but they have not yet reached the level of the hall master, so he does not agree to this matter.
