In less than half an incense stick, Xiao Yan refined nearly twenty pieces and returned the five pieces that destroyed Ji Yi to him.

"Do you need it?" Xiao Yan looked at Gujiu and asked, and Gujiu shook his head.

"We have never gone deeper, nor do we want to go deeper. The demon flame is not something we can get, so there is no need." Gujiu waved his hand and said, still very clear about how much he has.

After Gujiu said that, he made a gesture of invitation. Xiao Yan nodded slightly and followed Gujiu towards the bottom of the giant tree.

The giant tree is extremely large, with several coiled roots. When it really reaches the bottom, it is discovered that it is as complicated as a huge maze.

There was also a layer of gray mist covering the ground, which made the surrounding vision extremely blocked, but under Xiao Yan's powerful soul power, it was no problem.

Only after going deeper can you find that under this giant tree, the roots have formed a hollow space, and here you can feel the extremely rich surging of the source energy.

Soon everyone came to a huge tree root, which almost blocked all the way. At this time, Gujiu's handprints changed, forming a special mark. As soon as he raised his hand, the huge tree root slowly moved from the inside out in a rumbling manner.

As the tree roots continued to move out, they saw that the tree roots that were constantly moving turned purple and red, and there seemed to be flames burning on them. After seeing this scene, Xiao Yan's eyes slightly condensed. With the heat waves coming from the pavement, Xiao Yan could conclude that just such a flame was stronger than the strange fire and was close to the level of the heavenly fire.

However, it is still far from reaching the level of the Heart of Fire. But since everyone is here, Xiao Yan has to go down to figure it out. Whether it is the Heart of Fire or not, he can go to find out what kind of world and strange fires are there in this world of Ten Thousand Demons.

The roots of the tree were completely pulled out, and the purple-red flames continued to burn the roots. With the roots of the tree, a huge cave appeared on the ground, accompanied by the gushing heat waves and extremely rich source air.

Xiao Yan also suddenly understood why many people in the Guling Bird clan had this aura of flame, probably because they came here to practice.

In this pit, I saw purple-red flames swaying. When I approached and looked, Xiao Yan felt a little numb and looked down the pit. A group of figures appeared in front of me, all of whom were crawling on the wall of the pit, with long limbs, constantly crawling out of the cave.

"Sir, take the Golden Pill of Avoidance!" At this time, Ji Yi reminded him, saying that he had swallowed the Golden Pill of Avoidance into his stomach. At this moment, if he looked carefully at Ji Yi's eyes, a purple-red flame flashed by.

Xiao Yan also frowned slightly, and raised his hand to swallow the golden elixir of avoidance. The moment the golden elixir of avoidance was swallowed down, the picture in front of him became completely different again. When he looked down at the cave, the figure before him was gone, only those purple-red flames burning along the wall of the cave.

"Interesting... I can actually ignore the power of the soul." Xiao Yan also showed an interesting look on his face.

"Two sirs, our clan is just practicing here and has never stepped into this cave. I don't know what the situation is, so I can only send it to the adults." Gujiu bowed his hand and clasped his fists slightly, and Xiao Yan nodded.

"You are waiting here. If someone comes, you will crush the jade slip." After that, Xiao Yan raised his hand and handed it to Gujiu.

Gujiu did not dare to be negligent, so after taking the jade slip, he bowed his hand and fisted.

"Let's go, don't stand there." Xiao Yan said, and Ji Yi smiled bitterly. It's fake to say that it's not afraid of it. After all, this demon flame is very famous in the world of Ten Thousand Demons. Although the demon flame is extremely tempting, it is also extremely risky. There are countless people who die for him. It can be seen that this is still very dangerous.

However, the soul blood was in Xiao Yan's hands, and he was dead even if he advanced and retreated. He had to grit his teeth and gritted his teeth and even wanted to go up. After saying that, Ji Yi's eyes were straightened and he took a step forward and stepped into the cave with purple-red flames.

A sound came after a moment.

"Sir, you are safe for the time being, you can come down." After Ji Yi's voice came, Xiao Yan slowly entered the cave. Gujiu looked at Xiao Yan's background from behind and sighed secretly. With such a strong strength, he was so cautious.

After Xiao Yan stepped into the cave, it was not deep, but only a few dozen feet in the end. The further down, the purple-red flames became more and more violent, and the heat wave covered the place. Obviously, Ji Yi did not expect such high temperatures here, which made Ji Yi's face become more and more gloomy.

However, Xiao Yan was naturally walking on flat ground in it. Such temperature would not feel any discomfort for Xiao Yan.

The cave continued to extend forward. At this moment, Xiao Yan paid attention to the surroundings. As he continued to move forward, the cave became wider and wider, like a huge underground world.

Xiao Yan looked around and looked at the ground. Xiao Yan found something was wrong. If no one came in here, there should be no sign of anyone walking by, but at this moment, Xiao Yan saw some footprints under their feet.

"Can you have already been climbed here first?" Xiao Yan murmured in his heart, not knowing if Ji Yi came here alone, or there are other places where he could come here in addition to the bottom of the giant tree.

Although it has entered the depths of the cave, purple-red flames spread everywhere, so that the entire underground is bright and even looks a bit spectacular and beautiful.

The two of them were still moving forward carefully. After about half a stick of incense, the real underground world finally appeared in front of them. The space here was extremely huge. At this time, the two were only in a tiny hole in the rock wall. It looked like a huge canyon.

Moreover, this place is not lonely. The sound of beast roars came from the canyon, and many figures could even be seen in the air.

"It seems that it's quite lively here." Xiao Yan said, but the figures of these people felt something was wrong. Although they were hanging, their postures were very strange. They didn't look like a normal person's straight body, but stood in various strange postures.

Including some monsters, it was also very strange. When a huge salamander passed by Xiao Yan and the others, he could clearly see that the pupils of the salamander's beast's eyes were completely gone and were replaced by the fiery red flame.

Looking into the distance, a figure stood in the center. The figure was slender and slowly raised its palm, and a purple-red flame rose from its palm.
