This immortal cultivator is different from what I imagined.

Zhou Jingbian took the lead and flew down with his flying sword. After passing through the hole, the space below became wider.

He lit up a fireball that illuminated the surrounding area, but it couldn't reach the edges. It looked like the space was quite large.

Several people followed one after another.

After everyone arrived, several people stepped on flying swords in mid-air and carefully fell downwards.

Falling to the bottom of the cave, looking at a river in front of them with the light of the fireball, several people fell into silence.

There is an underground river. It seems that this underground space should be quite large.

Everyone shot a light ball out, and the illuminated space became brighter and larger.

The surrounding area was empty, with the river extending in two directions, and it was impossible to see where it was leading.

"Let's look around. This cave seems to be quite big, and it may lead to other places."

Zhou Jingbian said as he held up the fireball and walked towards one end of the river, followed by several people.

Yun Lingxi looked around and felt that the underground cave was probably very big, otherwise it would be impossible for them to just randomly choose a central location and open it.

In the dark cave, a few people explored with a piece of light. Wherever they went, there was light.

Walked along the river for a while.

"There is actually a fork in the ground?" Yun Lingxi was surprised.

Looking at a passage that appeared on the right side ahead, several people looked at each other.

"Let's go take a look at this fork in the road." Yun Lingxi suggested.

Several people turned around and headed towards that passage.

After walking for a while, the passage went all the way down.

After walking for a long time, I found nothing. There were only rocks along the way.

"There is light ahead." Zhang Ye was very excited. After walking for so long, he finally found something.

"Go and have a look." He was not the only one who was excited. Zhou Jingbian quickened his pace, and several others quickly followed.

After rushing all the way to the light source, the terrain ahead became more open, and a large circular cave appeared in front of us.

"Is this earth fire?" Zhou Jing frowned while looking at the red fire pool in front of him.

"Why don't you feel hot?" Zhou Zhenyang was surprised.

Several people stood at the entrance of the cave and did not move forward. This scene looked too weird.

The red fire light illuminated the surrounding area brightly. The space was not small, with a circular fire pool in the middle and a circle of flat ground surrounding it.

The magma was flush with the ground. It was obviously a pool of fire, but it didn't feel warm at all.

"What's going on?" Zhang Ye frowned.

Yun Lingxi took two steps forward and tried to reach out and explore.

"I don't feel the existence of the formation. It shouldn't be the formation isolation, but it doesn't seem to be a natural formation."

Zhou Subai frowned: "You guys wait here, I'll go over and take a look."

"Be careful." Zhou Jing warned his brother while looking at him.

"Yes." Zhou Subai nodded in agreement and walked forward slowly.

A few people stayed at the entrance of the cave, carefully observing the surrounding situation to prevent accidents.

Zhou Subai walked carefully to the fire pool and felt a little weird looking at the rolling lava.

"This lava doesn't look real."

Ok?

"Is the magma still fake? Or is it not magma but something else?" Yun Lingxi asked.

Zhou Subai shook his head, "It looks like magma, but it doesn't seem to exist."

"It can't be an illusion, right?" Yun Lingxi was surprised. Could it be that they had stepped into an illusion unknowingly.

After thinking about it, Zhou Subai stretched out his hand to pick up a stone and threw it down.

Then I saw that the stone rolled twice on the magma and then stopped on the magma.

The magma is rolling below, but the stone is motionless.

Seeing this scene, several people also came over.

I walked around the magma pool and found nothing.

Yun Lingxi tried to send a stream of spiritual power to the magma pool, and a ripple rippled on the magma pool.

"There is a formation on the magma. Could it be that someone set up a formation beside the magma pool to isolate the temperature of the earth's fire?

But what kind of material is needed that can not be affected by the ground fire and lay out the formation at such a close distance? "

"Can you tell what the formation is?" Zhou Jing turned around to look.

Yun Lingxi shook his head helplessly, "I can't tell. I didn't see any traces of the formation. Maybe the level of this formation is too high and my practice is not enough, so I can't tell."

"If there is a formation, does that mean there is someone here?" Zhou Zhenyang asked.

Several people pondered for a moment and looked around. Although they didn't want to admit it, it didn't seem to be natural.

Maybe the caves and magma pools are natural, but the magma pools must have been repaired later.

This formation cannot exist naturally.

But from the looks of it, no one has been here for a long time.

"Does this count as destroying other people's things?" Zhang Ye asked.

"Do you think the spiritual fruit we didn't pick before would be picked if someone discovered it?" Yun Lingxi asked.

Zhang Ye thought about it and concluded that he would definitely do it.

After all, although they left the formation behind, the fruit tree was not theirs. They just discovered it first and hid the formation behind it.

If others can break the formation, it's hard to tell if the fruit is not ripe, but if the fruit is ripe, they will definitely pick it away.

Does this mean that there is a treasure in the earth fire that was discovered by others, but cannot be taken away for the time being, so a formation is set up to prevent others from discovering or taking it away?

Thinking of this, several people stared at the ground fire with a little fiery eyes. It seems that there is a treasure!

"Even if this earth fire breaks out, we should be able to resist it for a while, right? How about we try to break it out with violence?" Yun Lingxi suggested.

Wei Zizhuang stepped forward and said, "Let me try it first. If the level of the formation is very high, we may not be able to break it easily. Please pay attention and see if you can tell anything."

If it doesn't work, let's try together again. "

Violent destruction may destroy things, so it is best to unlock the formation to be on the safe side.

"Well, okay, then you should be careful, I'm not sure what the formation is yet." Yun Lingxi agreed.

The few people retreated a little, and Wei Zizhuang took out his spiritual sword and struck it towards the magma pool.

The sharp sword light fell on the magma pool, causing ripples on the magma pool.

After some experiments, I saw that this formation cannot be destroyed easily.

Wei Zizhuang no longer held back his hand, gathered his strength and swung his sword.

The white sword light fell on the formation on the magma pool. The sword light, which could split the trial platform with one blow, still only caused ripples in the magma pool.

Wei Zizhuang's attack was fused with the sword intention he had comprehended, and the attack power was not a bit stronger than ordinary sword moves.

In terms of attack power alone, it is already the strongest move they can use. Even so, it only causes some fluctuations in the formation.

The level of this formation is definitely not low, at least the third level formation cannot achieve this level.

After looking at it for a long time, I couldn't see anything, so I had no choice but to ask Wei Zizhuang to stop first.

"I really can't tell."

Yun Lingxi was very depressed. It seemed that he needed to work harder to learn the formation.

"How about we try together? If it doesn't work, we have to wait until my father comes back."

"That's all it can do." Zhou Jing nodded.

Several people took action together, and the attacks fell one after another. The ripples on the magma layer became more violent, but they still blocked all the attacks steadily.

After attacking for a long time, it was still not broken.

"Forget it, let's leave it for now. Let's go look for anything else." Yun Lingxi stopped and gave up.

Several people also stopped, looked helplessly at the magma pool, and had no choice but to give up.

They can't break this formation unless they give up.

"Let's go." Zhou Jingbian took the lead and walked towards the exit, keeping out of sight.

When a few people came out, Yun Lingxi didn't even bother to set up the formation. There was no one in this vast mountain except them. What was the use of setting up the formation? It was a waste of materials, so be it.

Several people returned to the previous place and continued walking along the river. After walking for a while, they made another discovery.

They've come to an end!
