When the huge melting pot in front of Lu Li appeared, the other two people also quickly dispersed and opened up. They stood on one side of the challenge arena and divided the challenge arena into three parts.

Xie Guyuan and Jiang Kang also used the Ming Spring glacier fire and the broken gold fire to form a huge furnace. At their level, ordinary furnaces can hardly meet their needs. It is only by the power of the fire spirit that they can gather the furnace and cast the spirit weapon that they are more commonly used.

Among the three, the most powerful one is Naxie Guyuan. The rising of the broken gold fire is like countless golden lights, which makes his area look bright and dazzling. When the broken gold fire condenses into a melting furnace, the surging fire is also as bright as the melted gold.

And the Mingquan glacier fire in Jiang Kang's hand is also unusual. The ice dragon fire spirit directly wrapped the huge ice blue flame furnace in it. The huge dragon body slowly swam around the furnace, and the strands of ice cold gas continuously penetrated out, making the furnace look rather domineering.

In contrast, Lu Li is the most simple. However, where is Lu Li the kind of person who can endure? With a snap of the finger, No.2 and Yan Ge immediately nodded and immediately flew down in front of the huge furnace.

Between the two hands, suddenly changed a guqin, between the rhythm of the fingers, the sound of the Qin, actually like the water flowing gently, and the burning song, the body is directly transformed into a cloud skirt, a little toe, is accompanied by the sound of the No. 2 Qin, wearing a butterfly like dancing!

Granny Lianyin and the other three strong men were all looking at this scene with a slight trembling face, and their expressions were quite strange.

"Lu Li, what do you do with human form fire spirit?"

Grandma Lianyin was the first to roar.

"Tut, grandma, that's not true. I'm the sword elder of the craftsman's palace. Can people compare with each other casually? At that time, I will lose not only my own face, but also the face of the craftsman's palace! "

Lu Li smacked his lips. The way of righteous words was to give a thumbs up to the three great powers in a twinkling.

Granny Lianyin wanted to scold her, but after seeing Lu Li's self-confidence, she let down her heart, snorted a smile and scolded: "this boy, he loves to do these fancy things! It's no business

"Ha ha... Grandma, when you say this, won't your conscience hurt?"

The Lord of Fuhua Pavilion echoed with Lang's smile, "this boy, when has he been normal?"

"That's true. Let's see what he can do."

Nodded, grandma Lianyin no longer said anything, but turned her eyes to Lu Li.

On the challenge arena, Xie Guyuan was the fastest. With a wave of his hand, he put the long gun which looked like black charcoal into the furnace directly. The fire of broken gold was boiling. The fire of broken gold, which looked like red gold melt, immediately attached to the long gun. Xie Guyuan then threw a lot of ores and crystal stones into the furnace, Those forging materials, just like being activated by something in a moment, quickly decompose into various liquids, immediately condense and coil, and the speed is particularly amazing.

At the same time, Xie Guyuan's golden fire spirit also threw himself into the furnace. His figure kept flying around all kinds of materials. Every time he flew, he saw the impurities extracted from the materials. Except for the Dao furnace, with the cooperation of the two, the forging materials were soon purified!

"It's worthy of being the auxiliary flame used by the powers of the ancient universe. It's really a good thing..."

Lu Li looked at this rather harmonious cooperation in his eyes, but he couldn't help praising it in his heart. The effect of broken gold fire can save a lot of trouble in forging, especially in precision casting.

However, praise to praise, Lu Li's own hand movement is not slow, different from Xie Guyuan, Lu Li does not intend to let No. 2 and Yange help him in the process of casting, for Lu Li, although the two can greatly improve his speed, but that speed is not what Lu Li needs.

The process of investment casting, in short, is to restore the semi-finished artifact to its original shape, and then use better materials and more sophisticated means to improve its quality. In this process, the more you rely on the help of the fire spirit, the lower the plasticity of the finished artifact, because only the forgers themselves know the shortcomings of this forging and the direction to improve next time. The more skillful the forgers are, the more obvious these shortcomings will be in their own artifact. In this way, It's only now that there is the possibility of continuous improvement!

With a wave of his hand, there are a lot of forging materials in front of Lu Li. Among them, there are many top-quality crystal stones that Lu Li picked up from Zhou Yunhai. To Zhou Yunhai, these things are like a pair of glass beads with beautiful colors. They can be used as marbles to play with, and they are not round enough, These are precious treasures.

"With so many top grade crystal stones, does he want to smelt them at the same time without the help of Huoling?"

Seeing this scene, Su Yuan's face suddenly flashed an unbelievable color. Different forging materials have different characteristics. If they are forged in batches, it's all right. It's extremely difficult to melt them into a sword artifact. Even Su Yuan himself doesn't dare to smelt so many crystal minerals at the same time!

However, after some previous shocks, Su Yuan was obviously more calm this time. She surrendered her eyes to granny Lianyin and Lord Fuhua. As you can see, their faces were almost the same as her. In her calm, she was a little surprised, and her face was slightly trembling.

"Don't look at me, have you ever heard of the alchemy method that takes advantage of the medicinal materials?" Grandma Lianyin shrugged.

"Don't look at me either. The world of the blood amulet is coming out. Are you interested in learning about it?" The leader of Fuhua Pavilion also gave a smile.

Su Yuan can see that Lu Li is a miracle wherever he goes!

In contrast, Jiang Kang seems to be in order. However, his speed is not slow. He pursues them closely. In his furnace, there are many forging materials, which gradually melt and decompose. Although Mingquan ice fire is a variant cold fire, it still has the temperature that can make these materials melt away!

This process lasted about an hour. Finally, Xie Guyuan and his fire spirit were the first to complete the melting of all the materials, and all the materials in his furnace were integrated. When he wrapped the long gun in it, his hands suddenly moved: "aura, respect my will, gather spirit!"

With the sound of Xie Guyuan's mouth falling, the whole underground space is suddenly a micro earthquake. Immediately, there is a lot of aura of heaven and earth, and they begin to gather towards his melting pot!

Gathering spirit is the last step of precision casting. It can gather the aura of heaven and earth towards the artifact, make it shrink into the artifact, and integrate with the artifact. In this way, the artifact after precision casting can be promoted to the extreme it can achieve. The more Aura gathered, it means that the finished product of precision casting can reach a higher grade!

"Gather spirit to make casting... This guy wants to attack eight grade spirit weapon!"

This kind of movement immediately made Su Yuan aware that the method of precision casting is usually only used for the seven level spirit weapons. Although the three of them have different grades, they all have the same level of seven level spirit weapons. How dare Xie Guyuan's black spear have the top level of seven level spirit weapons? At this moment, if his technique is right and he has gathered enough spirit weapons, Want to be able to use this to impact the level of eight level spirit weapon!

Forging is different from Dan Fu. There is almost no secondary means to improve the quality of Dan medicine, and lingfu rarely goes beyond the level. However, forging is different. Even if it is not eight grade repair, it can make Lingwu reach the level of eight grade by means of precision casting. Of course, it's not easy.

Rongyang was also noticed by Lu Li and Jiang Kang about the movement of Xie Guyuan. Jiang Kang saw that the material in his furnace had also been melted. With a wave of both hands, he suddenly uttered a loud voice: "the aura of heaven and earth, come into my array, gather the spirit!"

Listening to the movement in Jiang Kang's mouth, Su Yuan and the other three strong men were slightly surprised. Jiang Kang wanted to attack eight grade aura at the moment!

At the same time, these three people also began to worry about Lu Li. Both of them started to gather spirits. The aura in this underground space is not as abundant as the outside world. The quantity is not unlimited. If Lu Li moves too late, he can't compete with them at all

"Tut Tut, you're in a good mood. If you don't want to lose your aura, I'd better carry out my consistent style. I'm not going to take the ordinary road. I'll have to do it back and forth!"

Looking at their fighting posture, Lu Li suddenly broke his finger and threw a blood bead into the melting pot. Suddenly, the melting pot formed by the fire of Anning Ling Yan was a great shock. A voice of Lang ran also sounded from Lu Li's mouth.

"Blood is the seal, leading the soul into the cauldron, the method of spiritual fusion, the life!"
