After a while, she sighed lightly: "It's really the end, it's really an underground fault around here, the terrain is very complicated, and in a certain direction, there is still a faint heat emitted. ”

"What do you mean......" Yang Di was taken aback.

"That's right, it's supposed to be a molten flow underground, and there's supposed to be a fire hole around here. Ye Shenyu nodded.

Their current location is not to really fall into the center of the earth, but they can encounter the rock flow fire cave if they do not reach the center of the earth.

There must have been a crack in the earth's crust that led to the center of the earth, so the magma came up.

The heat emitted from the water is not very strong, indicating that the magma there has stopped and there is no sign of a large spurt.

"Then let's hurry up, our bodies are almost cold, and where there is fire energy, I can do alchemy. Yang Di was pleasantly surprised, ordinary people are afraid to avoid the underwater melt flow, but now he is ecstatic.

In that cave before, even if the Feng carp guys didn't come to disturb, it was difficult for Yang Di to refine the pill, and his fire control technique had made great progress, but the fire path cultivation was still very low.

If you want to make an alchemy, you need external help, compared to burning kerosene and burning charcoal, the underground thermal energy is simply a bunker!

In ancient times, alchemists often practiced at least one fire path treasure technique, and it was best to find some innate true fire and put it into their bodies to help them refine their own alchemy.

But both of these are not easy, especially the latter, the innate true fire is extremely difficult to find, and the income in the body also requires extremely high cultivation attainments, full of dangers.

As a result, most alchemists, when refining pills, will take advantage of the excellent environment, in ancient times, those Dan halls of the Great Sect of Cultivation often had treasures such as fire pools and divine flames, which were opened up by some cultivators who were powerful beings of creation and transformation.

If it is an ordinary loose cultivation pharmacist, there is no such condition, and there is one place that has become the best place for alchemy—the crater!

Huahai City is a coastal city, the geographical environment is not complicated, there are no active volcanoes within a radius of several hundred kilometers, so Yang Di was just thinking about it before, and he has been thinking about what extremely difficult pills to refine in the future, so he went to find a place with a volcano.

Now it's a godsend, in a desperate situation, after a series of disasters, finally bumped into a good fortune.

"In your current state, can you still refine the pill?" Ye Shenyu asked softly, naturally knowing what this guy was excited about.

"If you can't, you have to hold on, or we'll be stuck here." Yang Di said excitedly.

"Okay, let's go over then. Ye Shenyu chuckled and shook his head, took his hand, and swam in the direction of a cave, groping his way through the cracks.

"I hope we don't run into a rock flow eruption, we're unlucky enough!"

"You crow's mouth!"

......

Just when Yang Di and the others were seriously injured and actively looking for the fire cave in the underwater abyss, in the three-layer water, the seven phoenix carp, after some painstaking efforts, finally removed all the stones blocking the underwater tunnel.

A large crystal clear water bubble quietly drifted out of the tunnel, and the seven people wrapped in the water curtain enchantment, their faces were gloomy and full of murderous aura.

"Split up!"

The phoenix carp snorted coldly and asked everyone to separate to search, the water here is calm, almost static, even if it is separated, it will not be washed away in the dark.

At that time, with the perception and memory of the nearby hydrological geography of the spiritual sense, they can easily gather.

Moreover, at the moment, even if they are chased separately and killed, there is not much danger, that Dao Sect disciple has already been injured, and he has lost an arm, and when he encounters any of them, he has no chance of winning.

As for those two, they will not be taken seriously by a powerhouse of their level.

After the seven separated, they immediately swam in all directions.

However, after searching in the dark waters for half a day, the seven of them found nothing, this dark water is not small, but it has a boundary, like a hidden valley sealed under the water.

The seven of them had only been wandering for more than an hour before they reached the edge, and more than thirty meters in front of them and up were bare rock formations, and the bottom of the water was mud and sand.

"Damn!"

In a corner of this dark water, the phoenix carp, which was wrapped alone in water-repellent beads, was furious, and he lit a dazzling Dao fire.

Suddenly, a small sun seemed to light up in the darkness, which was a signal to summon others.

"Those three are gone!"

Soon after, the other six arrived, all with ugly faces, and they searched almost all the dark waters, but they could not find the whereabouts of the three men.

If they are ordinary people, it is normal to not be able to find a target in the dark, but they are all powerful monks, even if they can't see with their eyes, their spiritual sense can easily sense the movement of hundreds of meters around them.

Moreover, the waters are bare all around, and there is hardly any place to hide.

"Could it be that the three of them swam back along the way they came?" Ao Ji guessed in a deep voice, although the scope of this water area is not small, but it is sealed, except for the way from which they came, there is no other exit for the time being.

"Impossible! That wide passage connects to the underground river, and the higher you go, the more turbulent the water becomes, and you can't swim up against the current, but I went to investigate just now, and I was able to swim as far as I could, and I didn't find any trace of the three of them. Feng Li snorted and shook his head, not believing that there would be such a possibility.

Several other people also nodded their heads, they were all washed down from the dark river, so turbulent water, let alone upstream, even if they grabbed the rocks and climbed up, it was very difficult, just like carrying a waterfall to climb up.

Moreover, the passage is surrounded by bare water rocks, which have long been washed by the current and are very smooth, and they can't grasp anything at all, and they can't climb up with their strength.

"Hmm. Ao Ji also admits that this speculation is a bit unreliable, and if they can really get out, they will not be in a desperate situation.

That dark river is like a Huangquan road, it is easy to get in, but it is almost impossible to get out.

If they can't even hold the water beads and cultivate to the strongest phoenix carp, how can the three people who are already injured go against Tian?

In fact, this judgment is very right, after escaping from the tunnel before, Yang Di and the three of them didn't even think about returning the same way, unless they were fools!

"Perhaps, they fell into the maelstrom just now?" After a long silence, the strong man of the Tantai family said gloomily.

This person's name is Tan Taiyi, and when he was searching for Yang Di and the three of them just now, he also swam near the big whirlpool.

It's just that he didn't think that Yang Di and the three of them were as unlucky, and when he sensed the danger, he hurriedly stopped his figure.

The devouring attraction around that great whirlpool was so amazing that even a powerhouse of their level would be swallowed within 50 meters.

There is only a layer of mud and sand at the bottom of the water, and there is nowhere to grasp it, even if it is a monk, floating in the water, it is actually difficult to move, maybe it can discharge the true qi with both palms and retreat backwards, but in terms of strength, there is also a limit, and it is impossible to compete with the devouring power in that big whirlpool.
