In total darkness, there is hardly any visible light.

Halfway through the excavation, Lin Ye suddenly heard some agitation on the other side. Just behind the sealed mound, Lin Ye heard a thick wheezing sound again.

His heart was beating rapidly, and Lin Ye's claws stopped and slowed down his digging movements.

Lin Ye's visual range was compressed to three meters, and he couldn't see what kind of creature was in front of him at all. The mysterious creature would occasionally move around a few times, and the vibration from the feet of his legs on the ground was transmitted to Lin Ye's feet, and the vibration made Lin Ye's feet slightly numb. Lin Ye relied on this vibration to gradually judge the size of the creature that emitted the vibration.

Slightly larger than the caveman, it appears to have no eyesight, relies on sound recognition, or has other sentient abilities. Lin Ye's breathing became rapid, he had never faced such a terrifying monster, compared to the birdcatcher spider that almost killed him, this unknown horror made Lin Ye even more terrifying.

It doesn't seem to have found Lin Ye.

And now that he was finally able to observe this mysterious creature up close, Lin Ye naturally would not let go of this rare opportunity. Lin Ye hid in the cave. Waiting for this mysterious creature to pass through.

However, it kept blocking the hole, crashing against the side walls.

What is it doing?

The hairy rat that had thrown off Lin Ye before curled up in a small hole that had been temporarily dug, and the mysterious creature was alarmed by the cry of Lin Ye, who was in the nest before, and was now blocked in the escape route of the hairy rat. It trembled, not daring to make any sound, not even digging. It held something in its hands, its nose twitching, anxiously waiting for the danger to pass.

Of course, Lin Ye didn't know that the hairy mouse was here.

Sticking his head out, he saw the rudiments of the mysterious creature.

With a visual distance of less than three meters, Lin Ye saw the full appearance of the mysterious creature for the first time!

Lin Ye's heart screamed, and what was in front of him at this moment was a caveman dragon dressed in pitch-black "oil".

A pair of thick legs, covered with a black oil-like liquid, so black that they could swallow all light, as if they had fallen into a bottomless abyss. On its forelimbs it grasps an underground insect that has inadvertently passed by and has become food for burrowing dragons. However, the latter did not open its mouth to eat, and the "oil" on its forelimbs devoured the insect, which subsequently merged into the troglodyte dragon's body.

This way of eating is extremely similar to the phagocytosis of single-celled organisms - endocytosis!

The mysterious creature didn't notice Lin Ye, but the black liquid on its body felt Lin Ye's approach, and it split a tentacle from the inside, twisting and twisting, like a baby's palm, as if it wanted to grab Lin Ye.

Every time Lin Ye took a step back, the tentacles took a step forward. It had already locked on Lin Ye, and the speed at which it stretched out was getting faster and faster!

Instinctively feeling a chill, he commanded a small ball of flame, burning the outstretched tentacles directly.

Whew!

But this action immediately caused a fierce reaction from the cave dragon, it lowered its head, and in one fell swoop, it collapsed the entrance of the cave where Lin Ye lived, and at the same time blocked Lin Ye's retreat.

Just this action immediately made Lin Ye understand that it was not the burrowing dinosaur he was familiar with. The latter's movements are extremely stiff, not so much relying on autonomous consciousness to find, but rather as a puppet of ** control, the body seems to be constantly dissolving, but the strength is much stronger than those cave dragons, and it can crash through the thick earthen wall in just one stroke!

It's not a cave-dyngote!" Lin Ye exclaimed, and he immediately ran under the dinosaur's feet. The dinosaur's reaction was so slow that it couldn't even make out the direction of the sound, and it seemed to be dragged by the black oil covering its body before it turned around and chased Lin Ye.

A viscous black liquid dripped down, and the ground became so smooth that it couldn't even stand firmly on it.

"It's a cave-dwelling dragon. The system corrected Lin Ye: "It's just that the tissues of the body have collapsed." ”

With the first up-close encounter with the mutant dinosaurs, the sound of the system also changed subtly. The system said in a voice that Lin Ye couldn't hear, as if talking to itself: "Gene—collapse?"

Whatever it is, if you dare to attack him, you will have to pay the price!

After this exploration, and even seeing more terrifying hideous eyeballs than this, Lin Ye's courage has grown. Lin Ye had already regarded these black liquids as a kind of parasite, and when he thought about it like this, he immediately didn't feel afraid.

Fight back, of course!

"Wow!" Lin Ye suppressed the anger in his heart, and a ball of flame was released from his body, and the black flame turned into a bloody mouth, instantly confusing the dinosaur's face.

The terrifying black liquid was stimulated, and it actually wrapped the flame in reverse. Although it resembles oil, it is not as flammable as oil, and in the fierce stalemate, the black flame constantly consumes the black liquid, but it is also consumed rapidly.

Not only can it devour living things, but it can also swallow fire!

"It takes a long time for the Flame Feather Cloak to regenerate flames, so you need to be patient. The system prompted that this meant that Lin Ye's Flame Feather Cloak would not be able to release a second flame for a while.

You can't get close, and if you touch it and swallow it, it will be bad. Lin Ye's mind was thinking about the solution quickly. He immediately thought of the mysterious creature from before. The reason why those cavemen blocked the entrance to the cave must have been to deal with these mutant dinosaurs, and it seems that isolating them is indeed the best solution.

Of course, the mutant dinosaur wouldn't give Lin Ye time to think, it stepped out and slammed on Lin Ye. Lin Ye immediately jumped into the air. With this jump, he jumped to the top of the cave, and kicked his legs on the ceiling like a ball that kept bouncing, luring the crumbling cave dragon after him.

The blocked hairy rat naturally smelled Lin Ye's scent, and it immediately drilled out of the hole in horror, and when the mutant burrowing dinosaur attacked Lin Ye, the hairy rat drilled out of the hole like a rocket, and then quickly dug the cave back, and soon opened the re-blocked hole again.

Lin Ye naturally saw this hairy mouse, and he immediately shouted in a low voice.

"Wow!"

Wait for me!

A meal on the body of a hairy mouse. It turned its head and watched as the caveman dragon chased after Lin Ye, its beard moving. Seeing this familiar chick, the hairy mouse immediately knew that it was Lin Ye who saved its life.

One second, two seconds~

Lin Ye dodged the attack while calling out to the hairy mouse, he had no way to take this terrifying creature now, although he could hide in the depths of the passage, but he didn't want to lose the hairy mouse, a guide who knew the terrain.

As if he had finally made up his mind, the hairy rat did not run away, but squeaked. It had returned from the mine with a small piece of green natural stone in its arms, and it held it high, and this small natural stone had just been lifted, immediately attracting the attention of the mutant dinosaur in front of it.
