Three days later.

The Su Danyi Pavilion is located in a not-so-busy alley in the Immortal City, with few pedestrians. Occasionally, there are a group of immortal cultivators passing by in a hurry from here.

Yin Xuan found the Su Danwei Pavilion and looked at it curiously, and found that the shop was also very small, worse than Tianbaozhai. But the business here was quite good, and there were several foundation-building monks in the Pavilion discussing business with Su Chen.

She found the goods here cheap!

Whether it is buying elixirs and magic weapons, or placing an order to refine them specifically, the price here is extremely cheap. It is so cheap that there is almost no profit at all.

Therefore, although the location of this Danwei Pavilion is remote, there are still many inexpensive cultivators coming to visit.

This surprised Yin Xuan very much.

Su Chen and several foundation-building monks discussed a small order. After they left, they smiled and looked at Yin Xuan who was stepping into the cabinet.

"Senior Su!"

Yin Xuan hurriedly bowed and looked at the pavilion, full of doubt, and said, "I saw the various elixirs and magical instruments in the shop, and the price of them was almost unprofitable. There was no profit in this shop, so how could it last for a long time?"

Su Chen smiled and shook his head, "I just used these business orders to practice alchemy and weapon refining techniques. It will be closed for five years or ten years. I don't plan to keep operating it! By the way, what are you thinking about Mithril smelting? "

Yin Xuan suddenly realized.

Senior Su is a Jindan cultivator and an island owner of the Spirit Dan Alliance. He has many ways to make money, and I don’t think he has to rely on this to earn spirit stones.

Yin Xuan quickly took out a jade slip from the storage bag and handed it to Su Chen, saying, "I have brought the spirit-eating flying ant back these days. I have tried it several times and confirmed that it is correct. This technique can indeed extract extremely high purity mitr silver. This time I brought a family's mitr silver smelting technique and came to find Senior Su. Please check it out."

Su Chen nodded and took a jade slip handed over by Yin Xuan. The slip records the unique mitr silver smelting technique of the Yin family.

After reading it, he taught Yin Xuan a can of spirit-eating flying ants and complete insect-controlling techniques.

A newborn soul-eating mother ant and dozens of low-level spirit-eating flying ants.

Only with female ants can new flying ants be born and replaced by dead flying ants. Otherwise, the lifespan of the spirit-eating flying ants will last for at most decades.

"The spirit-eating flying ants are not ordinary docile spiritual pets, but alien vicious insects. They eat all kinds of spiritual objects. If they are hungry and their relatives do not recognize them, they may even retaliate against their masters, so they must strictly control their number.

Remember not to let the spirit-eating flying ants be too big. Raise dozens of them, and hundreds of them are enough to refine mitral. If more than one hundred are killed directly. Otherwise, their appetite is too big and there are not enough spiritual objects to feed them, which will cause a disaster. You only have a female ant in your hand to control the flying ants tribe and prevent them from surging randomly."

Su Chen reminded Yin Xuan.

"Um."

Yin Xuan's face turned pale when she heard all the terrible aspects of the Spirit-Devouring Flying Ants. She couldn't help but nod and carefully kept this can of Spirit-Devouring Flying Ants.

She wants to take these dozens of spirit-eating flying ants back to raise.

Of course, she is not as rich as Su Chen, and she can feed a huge group of spirit-eating flying ants, which can be used for fighting. She can only raise dozens of them in small quantities, which is enough to refine Misin.

"Senior Su, I secretly copied this Mithril smelting technique and did not discuss it with my father. We must keep it confidential when trading purification techniques and smelting techniques in private."

Yin Xuan said guiltily.

"I just used the Misilan Smelting Technique to refine a set of Misilan armor, and I will not pass this technique and refining objects to outsiders."

Su Chen thought for a while and nodded.

Since Yin Xuan doesn't want others to know, he naturally won't tell the public. The fewer people know about him refining the mitral armor, the better.

Su Chen tried Yin's Misilan smelting technique in the weapon refining workshop of his own Danwei Pavilion, and refined a protective gear widget to see if it was effective.

Yin Xuan also stayed to help and gave some key details.

Given the particularity of Mithril, there are only two normal methods of refining weapons.

First, the super-level weapon refining method. Use extremely high-temperature flames beyond a large level to melt the mitral. But this is only suitable for mitral silver below the third level. If a Nascent Soul Ancestor can do it, it can be melted. However, the fourth-level mitral silver cannot be melted, and the Nascent Soul level flame cannot be melted. It must be a cultivator in the God Transformation Stage to melt. This is obviously something that ordinary weapon refiners cannot do.

Second, the violent tempering method. Through hundreds of millions of times of repeated folding and pounding, mitril silver and other gold and iron are completely kneaded together and fully evenly. It takes decades to create a third-level mitril silver magic weapon, even a golden elixir monk.

Yin's Misilan smelting technique is quite magical. He took a different approach and cleverly avoided these two methods. This method is called "Sulphur Poison Silver Refining Method".

"Midsilver can unlock all kinds of magic in the world. However, if it does not destroy poison, it will be corroded and melted by various poisons. My ancestor of Yin spent hundreds of years to find a strange sulfur poison from thousands of different poisonous substances and completely dissolved it.

Then, the mitril sulfur poison melt was sprayed into the fourth-level black iron that had been melted at high temperature and mixed well. Finally, the poison was vaporized, and the mitril was precipitated again and was evenly integrated into the black iron."

Yin Xuan gave detailed instructions on the details of each step.

Especially the preparation of sulfur poison is the most critical trick. This accurate formula of sulfur poison is the true top secret of the Yin family. It was obtained after tens of thousands of tests. Even if outsiders know that sulfur poison is working, it is in vain if they don’t know the formula.

Su Chen nodded, and he naturally knew that Miltsil did not ward off poison. Because Miltsil spirit-eating flying ants could not ward off corpse poison, he had been killed by Zhuang Luyi many times. Other poisons could also hurt Miltsil.

He took a pound of fourth-level high-purity mitral silver and ten pounds of fourth-level black iron to test it.

The fourth-level black iron is extremely hard. In the high-temperature refining furnace, the extremely expensive fourth-level spiritual charcoal absorbed a large amount of fire spirit energy and burned for more than half a month before melting.

Then, he dissolved the mitril silver sulfur poison prepared by Yin Xuan and sprayed it into the high-temperature refiner furnace.

"Midian silver has been separated, it activates fire and cools very quickly. Immediately pour the melt into the mold."

Yin Xuan looked nervous and stared at the high-temperature stove.

The boiling hot furnace water made in a pot of refined mitrils began to cool down sharply because it was melted into mitrils.

Su Chen immediately waved his hand and poured the melt into the mold of a glove protective gear that had been prepared.

The originally boiling black iron furnace water completely cooled down in almost a few moments. The high-temperature fire aura was quickly completely repelled by Mitsunian.

A fourth-level Misilian glove protective gear was officially released.

This mitral glove protective gear exudes a mysterious and gorgeous silver light. The knuckles can be bent and closed, which is quite flexible. When you touch it, there is a little cold air.

Su Chen put this mitsilver glove on his hand and placed his palm on the fourth-level blazing spiritual charcoal fire to grill it. However, the fierce flames completely avoided the mitsilver glove, and he couldn't help but exclaim.

The fourth-level mitril silver gloves can withstand the flames of the Nascent Soul level! If a complete set of fourth-level protective gear is refined, it is enough to withstand the powerful spells of the Nascent Soul cultivator.
