Only by driving the sect's Nascent Soul Cultivator out of Tengyun Mountain could Xu Yan truly feel at ease.

How could he allow others to snore on the side of the bed? What's more, Xu Yan, the fake junior uncle, once his identity is exposed, he will be chased by the entire Dijian Sect, and Xu Yan can't stand it.

It was late at night and there was only Xu Yan, a living person left in Tengyun Mountain.

Standing on the top of the mountain and looking down at the huge sect in the night, an urgent feeling gradually came to my heart.

The mysterious giant bronze coffin under the cemetery, the second elder soul hiding deep in the ice cliff realm, and the corpse of the great elder Hongzhi from time to time, once these crises break out, each of them is in fatal danger.

The seemingly high-ranking uncle of the sect, in fact, Xu Yan is always in crisis.

"The realm of transformation is closed, Xiao Qianfu's soul should not be able to come out. The bronze coffin in the cemetery is too gloomy and I don't know what it is. The next Thousand Infants List should be about to arrive, and the ban has not yet been broken..."

With the night wind, Xu Yan stood on the top of the mountain for a long time. With his body moving, he left Tengyun Mountain with his sword and flew towards the direction of the Earth Fire Cave.

The Earth Fire Cave of the Dijian Sect is located in a valley in the mountains. There is no wood in the valley and scorched earth cliffs everywhere. There are huge caves in the center of the valley, which lead directly to the underground.

As soon as the Earth Fire Cave arrived, the heat waves hit the surface. Although it was midnight, there were endless disciples of the sect entering and leaving the Earth Fire Cave.

If disciples in the foundation-building or even Qi refining stage want to refine alchemy, the most convenient way is to use the earth fire.

Earth fire is strong and weak, and it is divided into two areas by Earth fire caves.

The weakest earth fire is suitable for disciples with low realms. If you specialize in the Qi Refining Period, you will have the opportunity to control it. The strong earth fire can even be refined with magic weapons.

The Earth Fire Cave is originally underground, so it naturally belongs to the Yunxia Peak Sect. There are as many as three Nascent Soul Powers guarding here. Tianjiao Lan Yushu is born in the Earth Fire Cave.

After choosing the stone chamber with the strongest ground fire, Xu Yan tried to lead out the ground fire to refine the bone of the feather.

After all, Cangming Temple is extremely far away. If the earth fire in the Earth Fire Cave can refine the feather-turned bones, Xu Yan would not have to go out.

In the center of the stone chamber is a stone platform with a wellhead shape, which is not bottom-out. There are four sag marks around the stone platform, which are similar in size to spirit stones, and are used to place spirit stones.

Only by urging the magic array engraved on the stone platform can you attract earth fire. This is the method of using earth fire in the earth fire cave.

In order to obtain the most powerful earth fire, what Xu Yan took out was not the lower-grade spirit stone, but four top-grade spirit stones. As the spirit stones were inlaid, a howling sound came from the depths of the wellhead, like a strong wind surging.

With a shout, a fire column of more than one person rushed out of the wellhead, and the temperature in the stone chamber rose in vain and the heat waves rolled.

Using spiritual power to protect the body, Xu Yan took out the bone of the feather, sent it into the pillar of fire, activated the spiritual power and began to try to refine it.

One hour later, the craziest stone chamber gradually calmed down, the earth fire slowly retreated, and the bones of the transformed feathers the size of the arm remained unchanged.

"It seems that I have to go to Cangming Temple. Such a level of earth fire cannot be used to transform the bones of feathers."

It was confirmed that the strongest gust of earth fire cave could not be refined into feather-turned bones. Xu Yan did not stay for a long time and would leave the earth fire cave after walking out of the stone chamber.

"Can uncle master successfully refine it? If you want to help, you can always speak." The person waiting outside the door was a fat Nascent Soul Elder, whose surname was Xu, was one of the Nascent Soul Elders who were in charge of Dihuo Cave.

"Thank you, Elder Xu, for your kindness. We are from our family. I won't be polite when we can use it." Xu Yan said casually, and suddenly remembered something, saying, "I heard that there is a unique skill in the Earth Fire Cave called the method of demon refining. Could it be that Elder Lan Yushu practiced?"

"That's true. Jade Book became famous by the method of demon refining. If it weren't for this, how could it be ranked among the three great geniuses?" The elder surnamed Xu smiled and saw him off. In front of his uncle, how dare he, an elder in the early stage of the Nascent Soul stage, be neglected.

"The name of the magic refining method is really weird. Can all disciples of the sect learn it, or can only disciples from the Earth Fire Cave practice it?" Xu Yan asked curiously.

"Disciples cannot practice it. It is not that they are not allowed to practice it, but that this technique can only be practiced at least at the level of the Golden Elixir. The method of demon refining is passed on to the Sword King Hall of this sect. It is one of the unique skills of the Sword Lord. It is a method of refining magic weapon puppets. It is divided into five realms, namely the Wood Man Demon, the Iron Man Demon, the Golden Man Demon, the Saint Man Demon and the Heavenly Man Demon."

Seeing that the uncle was very curious about the method of demon refining, the elder surnamed Xu immediately asked Xu Yan to walk to the deep hall of the Earth Fire Cave and even talked to his good words.

The method of demon refining is actually a puppet method. It refines puppets to fight the enemy. This puppet method has an advantage. It can judge attack and defense by itself, and may fight by itself. Unlike magic weapons, once it is out of the control of its owner, it can only become a dead object.

The puppet is also dead, but the puppet can leave the master for a period of time. The higher the level the puppet, the longer it can leave the master.

Xu Yan was unfamiliar with the method of puppets, and there was no such method in the bottle, so he became even more curious.

According to the fat elder Xu, the puppets of the five major realms correspond to different levels of magic weapons, the wood demon corresponds to the lower-grade magic weapons, the iron demon corresponds to the upper-grade magic weapons, and the gold demon corresponds to the power of the best magic weapons. When it comes to the saint demon, it is amazing. It actually possesses the power of the earth spirit treasure, but no one has seen the heavenly demon before, and it is said that it can compete with the innate spiritual treasure.

While speaking, the two came to a hall, which was covered by formations. As the elders of the surname Xu cast their spells, they opened. They contained the unique skills of the Earth Fire Cave lineage, mostly the methods of refining weapons and alchemy. Many of them were the experiences left by the Nascent Soul of the Earth Fire Cave in the Earth Sword Sect in the past dynasties. Such experiences are worthless.

In addition to the experience of the mental method of the alchemy art, there are also some fire control methods, the most precious method is the method of demon refining.

"My uncle is an elder of the sect. If you are interested, you can comprehend the method of demon refining at any time." The elder surnamed Xu respectfully pointed to a stone tablet in the center of the hall, which was engraved with the five realms of the method of demon refining.

Standing in front of the stone tablet, Xu Yan recorded all the dense inscriptions before he could finish his meal. It would be very troublesome to come to the Earth Fire Cave to comprehend. You can practice at any time by yourself.

In fact, the rules of the Earth Fire Cave are that the practice of demonic refining must be carried out in the Earth Fire Cave, which means that this Qimen skill is not allowed to be practiced outside, but Xu Yan's identity is there, and the uncle of the junior master is willing to write it down directly, who dares to say no?

The fat elder surnamed Xu made up his mind not to go too much, and let Xu Yan remember the whole set of methods.

"The inscription is a rubbing? Why does it seem incomplete?" After writing down the exercises, Xu Yan looked at a place that was obviously empty below the inscription and asked. If it were the entire exercises, there shouldn't be such a big blank.

"The inscription was passed down from the Sword King Hall, and it must have been rubbing."
