In the underground world, the number of creatures is unimaginable.

Basically every ten meters or so, at least one giant bug will appear.

Come to think of it, bugs exist in large numbers no matter what world they are in.

Bugs above the ground are only very small, so they are usually ignored.

But in this underground world, bugs are often three or four meters long, even bigger than Mimi Silver King.

There are also those strange and weird appearances. Xu Xin will feel a little bit of physical discomfort every time he sees them.

Big bugs and such are indeed much scarier than big brown bears and tigers.

Although their lethality shouldn't be that strong.

After all, most bugs give people a soft feeling.

Except for those big beetles.

He did not walk very fast, but shuttled through the jungle at a relatively constant speed.

The underground world also has soil.

These vines and giant plant-type monsters all grow in the soil.

but……

Xu Xin squatted down and grabbed a handful of soil.

The soil is dark red.

[Completely contaminated soil (ash): Soil infected by unknown forces has been completely eroded and is useless to survivors. 】

Really?

He just used his discerning ability to look around and found that the soil here was completely colorless.

There is gray-scale, useless soil everywhere.

"Huh...?" Coco also used her little paws to stir up the dark red soil in his hand.

Xu Xin was slightly confused.

By the way, where does this soil come from?

underground……

There shouldn't be soil, right?

Isn’t soil a substance that only exists on the surface of the earth?

Could it be that someone carried it underground?

Shaking her head and no longer thinking about it, Xu Xin stood up and continued walking forward.

The surroundings are not all gray and polluted soil.

There are also a lot of blue-level resources here.

For example, any stone on the ground is blue level.

However, Xu Xin was too lazy to pick up these things. Li Wenxi had complained to him more than once that there were too many stones as a by-product of mining.

There were already too many stones to use up. He didn't waste time anymore.

The pace of his feet was a little faster, because he found that this section of the road was much easier to walk than Xu Xin imagined.

The giant beasts and large monsters around him seemed to have little interest in him.

Every five or six hundred meters, one or two giant beasts at least twenty or thirty meters tall will appear.

Although these giant beasts look extremely ferocious, they do not kill each other, and they all keep a relatively long distance.

Looking at it like this, they seem to have divided their territories, do not invade each other, and seem to be somewhat harmonious.

The creatures in this underground world should have really formed a food web of their own.

Foreign humans like Xu Xin are not in their diet at all, and they have not provoked them, so they basically don't care, and entering their territory is not considered an intrusion at all.

Just like a tiger wouldn't consider a butterfly flying into its territory an intrusion.

It's too weak, I don't know if it tastes good, and it's not tasty enough to fit between my teeth, so I'm not interested.

Therefore, he felt that it didn't matter even if he didn't wear the cloak of the Invisible.

As long as he doesn't run too fast and arouse the behemoth's curiosity, there won't be any problems.

This is the best thing.

Although he thought so, he still walked cautiously.

After all, there are too many monsters in this underground world.

You can't be sure which giant beast is more curious, so you have to take action against him.

For example, right now, about two hundred meters ahead and to his left, there was a giant rhinoceros the size of a heavy truck lying on the ground.

It was lying on a pile of struggling mutated vines, its body remained motionless, and it was eating these moving vines leisurely and contentedly.

The surrounding mutated vines that were not suppressed launched various whip-like attacks on the giant rhinoceros, but the rhinoceros didn't care at all.

Because these attacks can't cause any damage to its armor-like thick skin.

Not even a trace is left.

After observing for a while, Xu Xin breathed out gently.

It's too strong, he can't deal with it at all.

Perhaps Ma Hongwei's new type of heavy crossbow, delayed explosion heavy crossbow, can cause harm to this rhinoceros.

Keep walking forward.

Ahead, there is more than just a huge rhinoceros.

Because, far away, he heard the sound of trickling water coming from ahead.

The underground world also has rivers and lakes.

Xu Xin took two steps and was stopped by Coco's "squeak".

Its little paws pressed against his breastplate, and its little head kept shaking: "Ugh..."

It seems that it is very dangerous over there, Ke Ke can feel it.

No matter on the ground or underground, any living thing cannot survive without water. Therefore, various kinds of creatures usually gather along rivers and lakes.

Including powerful beasts.

There are dangers along the river, that's for sure.

but……

"There is no way, Coco, we have to cross this river." Xu Xin looked forward, "This river has blocked our road."

"Ugh..." Coco whispered, expressing her helplessness.

Although there are thorns and vines in front of me, and I haven't seen the river yet, the sound of trickling water, the sound of water splashing in the water, and even the sound of something unknown jumping into the water all came from the front.

This front includes all directions ahead.

This means that the river is right in front of them.

Keep walking forward.

Because of his increased hearing, even though he can no longer observe the surroundings through maps underground, he can still identify the locations of surrounding animals through hearing.

Most of them are just bugs, so there is basically nothing to worry about.

Along the way, not only giant beasts, but also these big insects had no desire to attack him.

Soon, he walked to a position only thirty or forty meters away from the river and saw the river.

"Ugh!" Coco yelled, expressing surprise.

"...This is really..." Xu Xin frowned slightly.

The river is very wide, at least fifty meters wide.

Compared to the creek next to his tree house, it was much wider.

The river is not turbulent and flows smoothly.

But from now on, there is nothing unusual.

But the biggest exception is the color of the river water.

The water flowing in the entire river appeared pale red under the shining white light in the sky.

That’s right, this river is no ordinary river!

This should be a polluted river!

This can be seen from the vegetation along the river.
