Immortal cultivation starts with copying.

From the first floor to the second floor, the aisle in the middle is several miles deep.

When Chen Yunhao and Zhao Yuyang landed, they seemed to be in a huge and boundless underground cave.

It is not as dark as imagined here. There are some moss-like plants growing on the surrounding cliffs or on the cliffs above.

These plants emit a faint fluorescence, making the entire underground world not pitch black but somewhat bright.

The entire cave was filled with a faint mist, which was actually poisonous mist.

They sensed it when the three of them came down. Now some of them have spiritual shields on their bodies, while Chen Yunhao directly slapped a Vajra Talisman.

However, this Vajra Talisman could not last long, and the poisonous gas was corroding the spiritual power shield emitted by the Vajra Talisman bit by bit.

From time to time, some black liquid drips from the cliff wall at the top of the cave. It is also a toxic corrosive liquid.

Under the feet of the three of them was a rotten quagmire that had accumulated over who knows how many years. In some places, there were rocky surfaces protruding from the quagmire, but most of the area was a quagmire.

Bubbles would occasionally emerge from these swamps, emitting a pungent smell, and from time to time some ironclad beetles, unique to the swamp, would crawl out.

On the cliff wall at the top of the cave in the distance, there were some monsters hanging upside down in the air, which seemed to be black-winged bats, which are also a poisonous monster.

This second layer is also extremely vast, even larger than the first layer, but it is not a whole hole, but a large hole inside a small hole, with an area of ​​several thousand miles.

The nine-leaf black lotus is in one of the caves. The specific cave is also described on the jade slip. It is not far away, about a thousand miles away.

The lowest level cultivators who dare to enter the second layer of the Wuhui Abyss are Nascent Soul cultivators or above, and most cultivators operate within a hundred miles of the entrance.

Those who can get a thousand miles away are rare. Mahayana cultivators like Chen Yunhao generally don't come in. There is a reason why high-level cultivators don't come in.

Because this Abyss of No Return has existed for countless years, many powerful monks have come to explore it during this period.

After exploration by many cultivators, it was found that there were indeed some treasures produced on the first and second floors, which were somewhat useful for cultivators with low cultivation, but were somewhat useless for cultivators above the Mahayana stage.

Therefore, there are few powerful monks coming here, and those who can break into the area beyond a thousand miles are all by chance.

Especially on the second floor, there are many dangers. Even a Mahayana cultivator may get hurt if he is not careful.

Cai Lingyun identified the direction and flew straight forward without saying anything.

Chen Yunhao and Zhao Yuyang followed closely on the left and right. Although the three of them looked carefree, in fact, each of them had already been on alert, with their spiritual awareness outward, their eyes and ears open, and their ears alert.

With the cultivation level of the three of them, no matter the black-winged bats hiding in the dark, the venom dripping from the sky at any time, or even the iron-clad beetles rushing out from under their feet at any time, none of them could get close to them.

But we can't be careless. This place is called a dangerous place, and naturally it has its advantages.

Ordinary poisonous insects and creatures are just as powerful as ants, except for being more numerous. They can be destroyed with a single thought.

However, there are also terrible creatures under this swamp. They are extremely powerful. They are both monsters and insects. The strength of those who are powerful is not weaker than that of a combined body.

So even if the three of them meet, it will take some effort.

From time to time, black-winged symbols flew out from the darkness. They were all big ones, with their wings spread out over ten feet.

From a long distance away, it spewed out a ball of venom from its mouth, and the fishy stench was overwhelming.

These black-winged bats are not very strong, most of them are at the foundation-building level, but there are too many of them, and each one is fearless and unafraid of death, which is very annoying.

Finally, Cai Lingyun took out a magic pill, crushed it into powder, and scattered it on the three people.

This is a colorless and odorless elixir, but humans cannot smell it. However, it is very effective against poisonous insects and poisonous creatures, and it can instantly make the place much quieter.

The flying speed of the three people was actually not slow, but of course not as fast as in the outside world. They could not fly freely here.

In the time it takes to stick an incense stick, they have already flown hundreds of miles, and the journey has been relatively peaceful.

It seems that there is no road ahead, and there is a cliff at the end. However, this is just a cave, and there will be a special passage connecting to the next cave.

Just as the three were looking for the next passage, suddenly there was a loud bang from the mud below, and the smelly mud and water splashed all over the sky.

Zhao Yuyang reacted quickly, and with a low shout, a sword light flashed from his palm.

In the swamp below, a snake-like monster just emerged and was pierced through by the sword light.

It was a carrion worm with the strength to become a god, the overlord of this swamp, and the strongest one could reach the level of fusion.

What the three of them need to guard against is this ugly and disgusting carrion beetle.

The carrion beetle is quite powerful and good at hiding, but its defense is too poor and it can be killed by just one sword.

This was just a minor incident for the three of them. What they feared most was that the deeper they went, the more swarms of scavengers would appear, which could cause some trouble.

However, if these were the only troubles, Cai Lingyun could handle them alone, so there was no need to call Chen Yunhao and Zhao Yuyang.

So along the way, Chen Yunhao had been guessing that the danger after entering here should come from somewhere else, rather than the danger of the Abyss of No Return itself.

But now that it has come to this, no matter what Cai Lingyun's purpose is, he will help if he can within his ability, and withdraw if he can't. No one can force him.

The three of them quickly found the entrance to the next cave. There were three or four entrances here, leading to different caves.

The passage was only about one person high, barely enough for one person to walk in.

The three of them entered one after another. Behind the passage was a cave of similar size, which was also filled with poisonous quagmire.

As soon as we walked into the next cave, two scavengers as thick as buckets jumped out from the mud below.

Carrion beetles are most sensitive to fluctuations in spiritual energy. Although Chen Yunhao and the other two have restrained their auras, they are like three bright lights in the darkness, attracting the most carrion beetles.

With two bangs, two sword lights shot out and the two carrion beetles were directly blown off their heads.

One of the two sword lights belongs to Zhao Yuyang and the other to Cai Lingyun.

Don't think that Cai Lingyun is weak just because he focuses on alchemy. There is no simple one who can reach the Mahayana stage.

Among the three of them, Chen Yunhao is the weakest. On the surface, his cultivation is indeed the lowest.

Therefore, when making a move, try to lag behind by half a step, which is also a way to hide your weakness.

The two carrion beetles whose heads were blown off fell back into the mud. The mud, which was originally calm, suddenly became lively. Countless poisonous insects of all sizes swarmed over and began to devour the bodies of the two carrion beetles.
