"Disappeared into thin air?"

There was a hint of weirdness in Sunan's eyes.

Something that big is gone, and the underground magma is gone, as if nothing happened.

Even if it's him.

There's no way to make such a big thing disappear, right?

It's hard to do it.

Is there anyone still in the palace?

Sunan was puzzled.

After being stunned for a while, he couldn't help but smile bitterly.

"Hit sometimes you have to have it, hit no time you don't have to force it. ”

He hadn't thought that there was a palace underneath this place, but now that it was gone, it meant that it didn't have anything to do with him.

Then he found a place in the vast underground space.

Calm your mind.

Feel the rich aura of heaven and earth around you, and gradually consolidate the slightly fluctuating Fourth Zhang Spiritual Sea.

......

......

A week later.

Sunan, who was already covered in dust, slowly got up, and there was a crackling sound of bones on Zhou's body.

Seven full days of meditation.

The fourth zhang Linghai has been stabilized, and feeling that the strength in his body has increased several times, Sunan couldn't help but nod with satisfaction.

"It's time to go back. ”

The fourth zhang Linghai is stable.

His current strength is stable in the realm of golden immortals, above the earth, and no one is his opponent, he can already go back and settle all the new and old accounts before.

"Here's ......"

He just wanted to turn back.

But I inexplicably feel that there seems to be something under this underground space.

I've been cultivating before.

Although Shen Nian also noticed the strangeness, he didn't care. Now that the spiritual power has been withdrawn from cultivation, the movement underground seems to be getting bigger and bigger, as if there is some living creature!

Ever since that red-black palace and the magma have disappeared.

There was only a cylindrical black hole left under this vast space, which was pitch black and stretched downward.

Obviously.

It used to be a volcano.

And the location where Sunan is now is like the middle of the bottle, and there is still a deep space below.

"What could it be?"

After the divine thought probed slightly.

There were still more than 2,000 meters in the space below, and he was already more than 2,000 meters underground at the moment, with a total depth of nearly 5,000 meters.

Such space.

Humans can't reach it with their physical bodies.

Not only is there a lack of oxygen, but there is also an increase in pressure, even if it is a shackle venerable, it is impossible to reach five thousand meters underground.

"Can there be living creatures in such a deep place?"

Sunan frowned.

But the divine thought probe just now did detect that there was a huge space below, more than ten times that of here, and there was tiny biological activity in it. Because of the distance, I don't know what it is.

The palace before.

It had already piqued his curiosity.

Right now.

There are living creatures five thousand meters underground, and Sunan naturally can't help but explore it.

Plus.

This underground is where the spiritual veins are located, and there may be something good.

An idea came out.

After the red ball of light enveloped Sunan, looking at the black endless abyss below, Sunan did not hesitate at all.

One jumped and fell directly.

There are still more than 2,000 meters in Sunan below with divine thoughts, but in fact, there are 4,000, and the distance has doubled by half.

An abyss six thousand meters underground.

Even Sunan began to feel that as the depth increased, the pressure began to increase. Breathing began to become difficult, and the ears were also buzzing under the pressure.

Fortunately, the impact is not too big.

"Bang. ”

With a muffled sound.

Sunan descended from the sky and landed steadily at the bottom of the abyss, stirring up dust in the sky.

After the dust dissipated, Sunan was able to take a look at the specific appearance of the bottom of the abyss.

At the bottom is a huge space.

It's like the bottom of a bottle, and the space is much larger than where he was before.

It was pitch black.

The walls are pitted, with minerals and stones of various colors, as well as some flower branches of animals, pitted, not as flat as above, apparently naturally formed.

At the bottom of this great abyss, there is poverty.

There is not even a single grass except for the stones, let alone any life.

"Am I perceiving a mistake?"

Sunan frowned slightly.

When he was above, he could clearly feel the fluctuations of the life form below.

After inspecting one side in the huge space, suddenly, Sunan found a position in front of the side, and a subtle light emanated.

A few steps teleported to the front to take a look.

There's a passage here.

There were faint bursts of light from the passage, and the general outline of the entire tunnel could be clearly seen. It's so deep that you can't see the end at a glance.

When you come to the tunnel, you can see the situation inside.

The tunnel is five or six meters high and three or four meters wide. The source of the glow is a semi-crystalline stone in the tunnel, which hangs down from the top of the tunnel, like stalactites, large and small, glowing blue.

At a glance, the top of the tunnel is full of these blue and blue stones, reflecting the entire tunnel.

Compared to the outside.

Inside the tunnel, it was a different story.

Not only the glowing stones, but also the green creeper-like vegetation that fills the entire tunnel.

There are colorful flowers on the ground, as well as mushrooms of various colors, grass and trees.

If it weren't for the darkness and lifeless bottom of the volcanic abyss, it would really give people the illusion that they are on land.

"The world is so big, it's really amazing. ”

Sunan was surprised when he saw this.

If you hadn't seen it with your own eyes, who would have thought that it would be in an abyss more than 6,000 meters underground. There is a tunnel inside an extinct volcano, and there is indeed a thriving vegetation inside, and another scene of thriving business?

Even if he says it, others probably won't believe it.

Step into the tunnel.

The surrounding scorching temperature suddenly plummeted, returning to 256 degrees Celsius, and the air was no longer smelling of lime from volcanic rocks, but the fragrance of plants and trees.

But what surprised Sunan was.

in this tunnel.

There was a force that made him feel refreshed.

But I can't say what it is, it's almost the same as air, but it's different from Reiki, because this gas can't be absorbed, but it's not harmful to the body.

After walking forward for more than a minute.

A purple-black vegetation under the ground suddenly attracted Sunan's attention, making him slightly stunned:

"Is this a poisonous barrier grass?"

The grass was about the size of a palm, and two leaves grew from the rhizome the thickness of a thumb. The edge of the leaf has tiny needle serrations, and the serrations are covered with fluff, which are highly poisonous and kill when touched!

The name of this vegetation.

Or Sunan accidentally saw it in the herb encyclopedia that Lao Jun gave him, although it was highly poisonous, but after refining, it could make the holder inviolable. Moreover, the poison of this plant directly attacks the soul of people, and it is also of great help to the soul refining!
