"Before the head of the sect came, you were refining weapons here. This is the material you used."

Mu Chen took out all the things in the ring, and handed them out more than 70% of the materials to Yu Sichen. She put away the remaining materials and sat aside to calmly rest.

Looking at the materials in front of him, Yu Sichen felt a little bitter. If these materials really need to be refined, they would probably be as many as dozens of spiritual weapons. There were only about five days left before the auction. I was afraid that it would take me to refine them without sleeping.

He looked back at Mu Chen, but at this moment she entered the emptiness and darkness of entering into the meditation.

He was fiddling with the materials in his hand, recalling what Mu Chen said when he was learning to refine weapons, and the materials were classified and coded. It turned out that the large room was occupied by flat materials, making it look much smaller.

He took out a box with many grids and put the materials into different grids in a box. This was the box he had a sudden idea during his last practice. It was similar to a storage space container, and each grid was a small space.

After packing up, he also began to sit cross-legged and close his eyes, but instead of resting calmly, he was thinking about what kind of spiritual tools these materials would be refined into.

After a long time, he was still meditating, but Mu Chen woke up from entering into meditation and saw the box in front of him, which was a dozen grids of the same size, and now it was filled with materials.

Mu Chen didn't bother him. He walked out of the room by himself. Yu Sichen, who was meditating, woke up from the sound of closing the door. Many weapons and armor appeared in his mind.

"Since you have the idea, start working..."

When Yu Sichen saw that Mu Chen was no longer in the room, he began to refine his first weapon.

Take out the expected things from the material and start purifying them with flames. Over time, the material gradually becomes liquid.

This is a piece of meteorite iron. Under normal conditions, it is difficult for cultivators to refine it. It is already very difficult to melt it alone. It is usually used by high-level immortals to refine weapons. Unfortunately, Yu Sichen is still a rookie...

The meteorite that became liquid had no impurities, which made him wonder when he started smoothly. The principle of refining weapons was to refine it to the purest. Judging from his experience of using defective products when practicing, he could also extract some impurities, but there was no trace of this meteorite.

"What's going on? The spiritual consciousness clearly noticed impurities, but it couldn't be extracted..."

Yu Sichen looked at the liquid in front of him and said to himself. At this moment, a sound came from behind him. He looked back and found that Si Yuan was standing behind him, but he didn't notice it.

"Uncle Shi said you seem to be in trouble. Is there anything I need my help?"

Si Yuan is a middle-aged man. His clothes are different from those of other disciples. At this moment, he is moved by Mu Chen.

"Um……"

Yu Sichen felt a little embarrassed to speak. He couldn't do the most basic step in refining the weapon well. Isn't this slandering Brother Yi's face!

"Are you refining meteorite iron?"

Seeing that he was embarrassed to speak, Si Yuan probably knew what he was thinking, so he tried to break the deadlock.

"Yes, but some problems may be that I don't have enough skills, but I can only melt but cannot extract impurities."

Yu Sichen finally told the difficulties he encountered. Si Yuan did not express any expression. He just looked at the brother who had become sworn brothers with the ancestors and then looked at the Meteorite.

"Actually, you are already very good. Most of the people who can extract meteorite impurities in the cultivation world are high-level scattered immortals, and they probably need the level of the golden immortal. However, our Ziyang Gate has a way to extract meteorite iron, which is to use this."

Si Yuan said as he took out a big cauldron. The appearance was dark and not gorgeous, far from what he saw in a spirit-selling store, but the cauldron exuded a scorching smell.

"Is this a tripod for refining weapons?"

Yu Sichen heard Mu Chen say that when refining high-level pills, he will use a cauldron. Do you also need to use a cauldron for refining weapons?

"No, this is a tripod for alchemy. After our Ziyang Sect cultivates the true fire of the natal world, the master will cast a tripod for his disciples according to his attributes. This tripod can refine alchemy or purify materials, including the materials for refining weapons."

Si Yuan's explanation made Yu Sichen understand, but there was no need to refine weapons and alchemy after cultivating the true fire of the natal world. The rules of Ziyang Sect are really special.

"The Ziyang Gate's alchemy and weapon refining is not specially carried out. It can be said to be a by-product of our practice. The refining is to allow us to master the fine control of spiritual energy. The masters often make things difficult for the disciples and give us special materials to purify them. This is also to train us."

The next explanation made Yu Sichen understand the benefits of doing this. No wonder Mu Chen can be refined easily. It seems that he has been trained by Ziyang Zhenren a lot.

"Then can I show this tripod?"

Yu Sichen didn't want to borrow it. This was something given to his master, and the meaning was slightly different. If he spoke, he would definitely lend it to him, but it was just because of his identity.

Si Yuan did not hesitate and sent the cauldron to Yu Sichen's eyes. Yu Sichen did not use his hands to pick it up. He used his spiritual sense to scan the cauldron. Generally, cauldrons require considerable strength to play a role. However, according to Si Yuan, the disciples of Ziyang Sect will do some purification materials when they cultivate the true fire of their natal life, which shows that the cauldron is special. I am afraid that there is a difference in the part in the refining.

After scanning the various parts of the tripod, the detailed information of the tripod was imprinted into Yu Sichen's mind. He checked all the information. The materials were very ordinary, and even the refining techniques were very rough. Soon he discovered a difference, that is, he couldn't understand the formation, and he vaguely saw the amplification array, the fire lock array, and the fire gathering array. This is very common in spiritual weapons like the tripod, but the formations are incomplete. There is also an unprecedented formation. The three formations are combined into a chain formation with the fire gathering array as the center.

"What materials have you purified with this cauldron?"

Yu Sichen began to speculate on this unprecedented formation.

"The most advanced one is meteorite, but it is barely refined into a semi-liquid state and cannot be refined like you."

Si Yuan knew that those who could become sworn brothers with the ancestors must not be ordinary people, so even if he was stronger than Yu Sichen, he would not feel inferior, but would be surprised by Yu Sichen.

"If your master doesn't use a cauldron, can he purify the meteorite iron?"

The answer is about to come out. Based on Yu Sichen's identity, Si Yuan also answered truthfully.

"Just like when I use a tripod, I can only be refined into a semi-liquid state."

Yu Sichen nodded. It seemed that his guess was correct. This was completely the effect of a chain formation.

"Thank you, I'm going to have a retreat. If something happens, I'll call you."

Yu Sichen plans to study this formation, perhaps not just for refining this single purpose.

Si Yuan bowed and bowed, left the cauldron in the room, and slowly left the room.

======================

Yu Sichen, who was studying the formation, was always in the room, carving the formation on the ground, and referring to the formation on the cauldron from time to time, but he had no idea.

The amplification array, the fire gathering array and the fire lock array were gradually peeled out from the chain formations, and most of the intersections were the same. After the first formation was stripped away, Yu Sichen discovered the rules.

In the end, only the unknown formation was left. After searching all the jade slips and knowledge he had, he did not find that there were no similar ones like this formation.

He carefully carved the formation on the ground, because he would not know the name of the formation, and it would be safer to add some precautions.

After the final stroke of the formation was carved, he felt that there were signs of overdrawing of the spiritual energy. He portrayed four formations in succession, but this should not be the case. He looked at the formation in confusion.

In a moment, a lot of spiritual energy condensed in the middle of the formation, gradually gathering with the center of the formation, becoming more and more dense, and when it reaches a certain level, it no longer condenses.

"Why do you seem to have seen it?"

While he was murmured, he searched in his mind. As time went by, a place appeared in front of him, an image portrayed with spiritual energy.

"Ziyang Mountain?"

This image is a bird's-eye view of Ziyang Mountain looking down from the sky. The location of the houses and the staggered roads are all similar to this formation.

No wonder I didn’t feel the spiritual energy on Ziyang Mountain. More than a thousand people needed to practice were very huge, but I never saw the reduction in spiritual energy.

"Spirit Gathering Array?"

He knew the spirit gathering array, but it was completely different from this formation, and the position of the formation center was obviously different. The spirit gathering array was mainly gathered, but this formation alternated with gathering and dispersion, forming a wind heart like a tornado, and the spiritual energy was sucked by the wind heart and gathered.

"By the way! This periphery is a spirit gathering array."

At this moment, Yu Sichen realized that if he removed the heart of the array, it would be a spirit gathering array. The problem arose again. What is the purpose of this spirit gathering array?

He felt the spiritual energy inside and outside the array. He felt that this formation was not a simple spiritual gathering function. Sure enough, the spiritual energy inside the array was more active than the spiritual energy outside the array. In other words, the spiritual energy was condensed through the array. When he thought of the explosion during his study, all this made sense.

However, this formation is only an auxiliary function, and spiritual energy is used as a catalyst for the fire gathering array, which promotes the quality of the flame and makes it possible to refine higher-grade materials.

The problem now is that I understand it, but I can't use it. Although there is Si Yuan's cauldron, according to my comparison just now, I am afraid that I can't resist the calcination of my own flame.

Just as he was thinking hard, his eyes gradually closed, but the colorful humanoid emerged from his body. Seeing the formation hand carved the formation in the air. After carving the formation, the colorful humanoid opened its mouth and ate the formation into its body. The formation slowly landed in the position of the Dantian. There was a small flame above the formation, which jumped happily with the infusion of spiritual energy. At this time, the colorful humanoid disappeared into Yu Sichen's body.

Yu Sichen had been sitting cross-legged in the room for a long time. The spiritual energy outside the room became chaotic. Si Yuan was a little worried about going in and checking. Mu Chen grabbed him, shook his head, turned around and went to another weapon refining room.

The flames have grown a lot larger than before. At this moment, the flames are still devouring spiritual energy. The formations in the room still exist, constantly absorbing the surrounding spiritual energy, and then being absorbed into the body by Yu Sichen.
