Xu Xin has been walking for so long, and most of them are ordinary thorn vines that have not mutated, and the number of mutated vines is relatively small.

But all the vines along the river are mutated vines!

The branches of these vines stood up and swayed in the air.

The giant rhino just ate this kind of mutated vine.

Compared with the mutated vines on the ground, these vines by the river are not much thicker, that is, less than twenty centimeters in diameter, which is almost the same as the vines that Xu Xin encountered on the ground that were enhanced in special areas.

Moreover, the blood patterns on their vines are not as bright as the special areas on the ground, but are instead a bit dull.

These vines are probably the bottom of the food chain in this underground world, right?

It is equivalent to the grass on the ground.

Although there are vines that have not mutated in this underground world, just like the vine bush where Xu Xin was hiding just now, it is just a pile of vines that have not mutated.

But he seemed to have never seen other creatures eating those unmutated vines.

Whether it's giant beasts, giant bugs, or vegetarian animals, they basically eat these mutated vines.

It feels like they need to use these mutant vines to supplement something, something that ordinary vines don't have.

Thinking of the madness of these underground creatures when the Silver King appeared, Xu Xin seemed to understand.

"...Is it still mutant energy?" Xu Xin said to herself.

These giant beasts really lack mutation energy.

In their eyes, things without mutation energy are not worth looking at.

For example, Xu Xin now.

There was another burst of joy in his heart.

This is also thanks to Lou Fei'er and his bracelet, otherwise, he might not be as relaxed as he is now.

I just hope nothing happens to Lou Feier.

Holding the halberd in his hand tightly, he walked towards the vines.

"Ugh...!" Coco suddenly shouted, and at the same time, he also stopped.

He heard the splash of something emerging from the water.

Through the gap between the vines, he saw a three-meter-long pitch black beetle emerging from the river.

Just after it came out of the water, its body was shining, and the two dark horns on its head also reflected a metallic luster.

Then, walked in his direction.

...Is this guy coming for him?!

It soon approached the vine group.

At this time, the rhythmic vines swarmed and attacked the pure black beetle!

However, it is impossible for the lowest level of the food chain to stand up.

Even if it's just a relatively "ordinary" giant black beetle.

The two horns on the beetle's head did not move, and the mutated vines that were thrown were thrown on top, and they were cut into two pieces as if they were thrown on the blade of a knife.

But those thorny mutant vines were completely unable to break through the beetle's defense.

The pitch-black carapace was like an extremely powerful alloy, and these mutated vines could not leave any traces on it.

"Pitiful……"

"Hey..."

These mutated vines that dominate the ground and serve as killers of survivors in dangerous areas are actually so humble in this underground world.

No one can beat this.

The vines still wanted to fight with the beetle, and countless vines wrapped around the jet-black beetle, trying to tie it up.

But the beetle immediately spread its wings and took off!

Xu Xin's eyes widened.

This beetle also has wings! I didn’t notice it at all!

Under the high-frequency vibration, the surrounding vines were shattered into powder!

An entrance of about four meters has also been cleared by the river.

The other vines did not dare to continue attacking the beetle, they all retreated silently and continued to swing.

The beetle landed slowly, retracted its wings, returned to its original appearance, and walked towards Xu Xin and Coco again.

"Hey..." Coco shrank in Xu Xin's arms.

Xu Xin took out his halberd, held it tightly in his hand, and stood still.

Once this beetle takes action, he can just fight back.

However, he had no intention of taking the initiative to attack.

After all, this place is full of dangers, and finding enemies for oneself is really annoying.

Moreover, bugs usually live in groups. If you kill one and lead to a bunch of them, then he is really in trouble.

Is this guy really here for him?

Why does it emerge from the river?

But things didn't seem to be what he imagined.

This pitch-black beetle, which was at least three meters long, passed him by.

Just as he was passing by, this jet-black beetle turned its head and glanced at him, opening and closing its mouthparts slightly.

The wings vibrated slightly and made a somewhat clear sound.

Then, the giant beetle ignored Xu Xin and turned its head and crawled away.

"... Huh?" Coco looked at the back of the giant beetle, tilted her little head, and sounded a little confused.

Xu Xin breathed a sigh of relief.

This giant beetle is too easy to deal with the vines, and its true strength is probably very strong.

If he were to fight alone, he wouldn't be afraid, but with so many monsters around, it would be better not to fight them.

So, this big beetle just comes to the river to drink water?

"Ugh!" Coco pushed Xu Xin, pointed at the big beetle that just left, and then made gestures with his two little claws, "Uh-huh!"

Xu Xin was stunned for a moment, then shrank.

He suddenly turned back to look at the giant black beetle.

But in just a few seconds, the beetle was gone.

"...You mean, that beetle just made a sound to tell us...not to enter the river, otherwise there will be danger?"

"Rebirth of the Great Era of Fighting Waves"

"Hey!"
