The size of this dormant volcano on the ground is quite huge. After going deep into the mountain, it is found that the space underneath is ten times the surface area.

The immortal cultivator who followed the two said anxiously: "The area here is so large that we can't find the tomb in time. The longer we miss the agreed time, the more disadvantageous it will be for us."

Chen Xiao also understood this truth, but he had to remain calm and not show his inner anxiety.

Xi Yunting said: "The only way now is to alert the enemy. Use all the detection methods you have. The larger the range of the spell, the better."

Everyone followed his orders, and all of a sudden, lights of various colors shone in the cave, and various fluctuations of true energy mixed together, making the interior of the cave brighter.

After a while, someone suddenly said in surprise: "We found traces of evil cultivators passing by here!"

Xi Yunting and Chen Xiao hurried over.

The immortal cultivator who made great contributions was a disciple of the Jin Chan Sect who was in the Nascent Soul stage. He was of the same generation as Jinghui, but his cultivation was much lower than Jinghui’s. His name was Ruicheng.

Chen Xiao looked at his short hair and said in a daze, "I actually forgot that your Jin Chan Sect has several spells that are specifically used to detect evil magic."

Rui Cheng was a shy person, he said sheepishly: "It doesn't work every time, it's a special spell for evil spirits."

Anyway, it's good to have discovered something.

Gather all the people, form a formation, and continue to go deeper into the depths in the direction where the reaction was detected.

There was magma flowing everywhere. At the beginning, there was more ground than magma. The deeper you went, the less ground there was for people to walk on. Gradually, the magma became a stream and then a river.

Eventually, they were blocked by a large lava lake.

Rui Cheng shook his head and said, "The spell reaction has disappeared."

Xi Yunting looked around and said in a deep voice, "Look around to see if there are any traces."

After everyone dispersed, Chen Xiao took out the water bag and drank a few sips to replenish the lost water.

It's too hot here and the air is not well circulated. If he wasn't in such a strong physique, he would have been unable to bear it.

Xi Yunting looked at him worriedly and whispered, "Brother Xiao, how do you feel?"

Chen Xiao took a sip of the water on his lips and said, "I'm fine."

Xi Yunting held his hand and felt relieved when he felt that the temperature of his hand was still within the normal range.

With repeated physical strengthening, cultivators' ability to adapt to extreme climate environments is gradually increasing.

For example, the tolerance of high temperature in the Foundation Establishment Stage is around 60 to 80 degrees, and that of the Golden Core Stage is twice that of the Foundation Establishment Stage. With each promotion to a higher realm, there will be a certain degree of increase.

Standing in the huge cave below the large area of ​​magma, these immortal cultivators rarely feel uncomfortable. What's more, Xi Yunting, who is in the Spiritual Severing Stage, can jump directly into the magma without any protection.

"Let's go look for him too." Chen Xiao shook Xi Yunting's hand.

The two of them split up and began searching along the edge of this huge lava lake.

After walking around for a long time, even with the speed of a cultivator, he circled the lava lake, but still couldn't find anything.

Chen Xiao returned to the place where they entered and stood beside the lava thinking.

He looked up at the top of his head.

At this time, Xi Yunting came over and asked, "Do you think it's above your head?"

Chen Xiao looked at him and said, "I don't know. But there is no other place except the top of your head and inside the magma."

Xi Yunting thought for a moment and said, "I'll ask a few people to go up there, and you come with me into the magma to take a look."

Chen Xiao nodded and said okay.

After arranging people to search on the top of the head, Xi Yunting and Chen Xiao went down to the lava lake.

The temperature of the magma here is not very high, only about 700 to 800 degrees, and the magma is between cherry red and orange.

There were some floating bodies in the middle. Chen Xiao and Xi Yunting stepped lightly on them and went deep into the center of the magma lake.

"Look! There's something there!" Chen Xiao spotted an object the size of a washbasin in the lava.

Xi Yunting flew up directly, Chen Xiao jumped over and stood lightly on top of him.

He looked carefully and found that it was a short stump of a stone pile. The area below was even larger and as thick as two people could hug together. He reached out and touched the surface, then looked up and said, "This could have been a pillar that was cut off."

"Wait a minute, I'll go take a look around." Xi Yunting said.

Xi Yunting was very fast and he came back after going around the area in less than five minutes.

He shook his head at Chen Xiao and said, "I didn't see anything else."

Chen Xiao was not surprised. He said, "They must have been chopped off by the evil cultivators. If we hadn't come to the center, we wouldn't have discovered this stake."

Xi Yunting said: "The entrance to Yan Duo's tomb should be from here."

Chen Xiao said: "The evil cultivator cut down the pillars because he didn't want us to find the tomb. He will intercept us from below."

"We have to go down even if there is an interception. Time is running out." Xi Yunting made a prompt decision and sent a flying message to the people who were still there.

After everyone gathered together, Chen Xiao and Xi Yunting discussed it and decided to leave behind a few people who had reached the Nascent Soul stage, while those who had reached the Out-of-Body stage would follow them into the magma.

After entering the magma, Chen Xiao felt a burst of heat. His skin was protected by his vitality, but his mouth and nose were submerged in the magma. He casually stuffed a bead into his mouth.

Because they knew they were going to a place with fire this time, everyone wore heat-resistant clothing, otherwise they would be naked as soon as they got down.

There is no vision at all in the magma, and Chen Xiao can only rely on his perception to explore the surrounding environment.

The magma lake was bottomless, and after coming down, the Taoist practitioners unknowingly distanced themselves from it.

Just when Chen Xiao was about to use his aura to find Xi Yunting, he felt that the magma flow around him was abnormal.

His heart skipped a beat, and Chen Xiao summoned the compass without hesitation and held it in front of him.

A stream of white magma with extremely strong impact rushed towards him. If he had not used the compass to pour the magma into the universe in the disk in time, he would have been in trouble.

Chen Xiao was shocked and angry after being ambushed. The star symbols on the compass in his hand lit up, generating tremendous star power. Chen Xiao threw the compass out.

Suddenly, the magma surged like a river and the waves became turbulent.

The evil cultivator who launched the sneak attack did not expect that Chen Xiao could create such a huge wave in the magma. He was swept away by the tide and his body was unstable. Before he could steady himself, Chen Xiao pounced on him and chopped him to death with the Xingshan Axe.

As soon as the man died, his body began to burn violently and turned into ashes in a short while.

Chen Xiao stretched out his hand to summon back the compass and moved in another direction.

On his way to find other people, he encountered an evil cultivator who was looking for death.

The cultivation levels of these evil cultivators are at the Nascent Soul and Out-of-Body stages. The Taoist cultivators are not afraid of a head-on fight with them, but the white magma flows they control are more difficult to defend against.

He wandered around for a while, and apart from killing several evil cultivators, he did not encounter a single Taoist cultivator.

In the end, he had to give up and followed Xi Yunting's aura downwards, where he saw another stone pillar.

There was a huge chain fixed on the pillar. Following the chain, he finally found a man-made underground channel in the lava.

He passed through the culvert and floated up out of the lava.

There was a fierce battle on the lava surface. Xi Yunting was fighting against a hundred of them alone, killing the evil cultivators so badly that they were pissing and running.

When Chen Xiao jumped out of the lava, he noticed that on the dark rock walls around him, there were countless streams of lava flowing down like waterfalls, which was extremely spectacular.

The flowing magma gathered below, and on the magma there was a huge chain-like passage, at the end of which were six huge stone towers.

There are five stone towers arranged in a pentagram shape surrounding the periphery, with an exceptionally large stone tower with a pointed roof in the middle.

At this time, another person emerged from the magma. Chen Xiao took a cautious look and saw that it was a Taoist practitioner who was traveling with him.

"Master Chen, look! There is someone on top of the tower!" The man jumped out of the lava and said with sharp eyes.

Chen Xiao glanced up at the tower. There was a circle of high platforms extending from the stone tower. There were figures sitting cross-legged there. The fight was in full swing here, but those people did not move at all.

"They... they won't die, right?" the man said.

"Don't let your imagination run wild. You stay here to meet the others, and I'll go and lend a hand to Yun Ting."

Chen Xiao rushed over and joined Xi Yunting. The two of them worked together to beat these evil cultivators so badly that they had no chance to fight back.

Maybe the cultivation level of these evil cultivators is quite good, but they can only be beaten by the two people who seem to have cheats.

Leaving behind countless corpses falling into the lava, only a few escaped to the stone tower.

The battle here is over, and those who should have come up over there have all come up, and those who couldn’t come up will probably never come up again.

The first person to come up said somewhat sadly: "Five people did not come up."

Xi Yunting said coldly: "Kill all these evil cultivators and avenge our dead comrades!"

With just one sentence, he ignited the somewhat depressed atmosphere and boosted the morale of these people.

"That's right! Kill them all! Avenge our dead fellow Taoists!"

The group flew towards the stone tower, but looking at the stone tower so close before their eyes, they couldn't get closer no matter how hard they flew.

Chen Xiao frowned and said, "There is a magic circle here. How come those evil cultivators can get close to the stone tower and hide inside it, but we can't get close?"

Xi Yunting thought for a moment and said, "Did you notice that those evil cultivators just now entered the stone tower by falling on the chains?"

Chen Xiao suddenly realized that this seemed to be the only way to enter the stone tower.

Following the evil cultivators' method, they stepped on the chains and indeed walked into the vicinity of the stone tower.

The six stone towers are linked by chains, and these chains follow a certain pattern. Some fellow Taoists believe that there may be a magic circle on top, and you must pass through the correct chain to get to the desired place smoothly. If you encounter the wrong chain, it is likely to trigger an attack spell.

The cultivators who are chosen to follow the Shenzhou Atlas are both knowledgeable and patient, and are well prepared for their main duties in every aspect.

"How long will it take you?" Xi Yunting asked the formation master.

The formation master said with difficulty: "I have never seen this kind of formation before. I can only give it a try."

Xi Yunting said calmly: "Do your best."

Just as they were waiting for the formation master to find the correct passage, the flow of magma on the rock wall suddenly increased, and the color slowly changed from orange-red to golden yellow, and then from golden yellow to white.

As the flow rate increased, the magma level also began to rise rapidly, rapidly approaching the chain they were on.

Seeing this scene, the Taoist practitioners' faces suddenly changed.
