"Where does this passage lead?"

The passage discovered by Lin Chao was obviously dug by hand, and it seems to have a long history. Due to the movement of the mountain, the entrance to the passage was buried, and by coincidence it was excavated by him.

Digging the entrance of the passage, there was a gust of wind generated by the flow of air inside, it seems that there should be other exits to this passage, and there may be secrets of the Xi tribe hidden in it.

The inside of the passage is very damp and dark, and it seems that a swarm of terrifying prehistoric insects will pop up at any moment.

After hesitating for a while, Lin Chao decided to explore first, maybe he could find the secrets and clues about this primitive world.

This artificially dug passage is very spacious, and with Lin Chao's huge size, it is completely passable, so you can imagine how much effort the ancestors of the Xi tribe spent in order to dig this passage.

What made him wonder was why the ancestors of the Xi tribe had spent so much effort to dig such a passage in the belly of the mountain, what was hidden in it?

The answer lies in the belly of the mountain at the end of the passage.

Drilling into the passage, Lin Chao found that the surrounding rock walls were very smooth, and there was a layer of wet white slime on it, which was obviously left by some kind of prehistoric giant worm.

The ground is also slippery, and the passage is not completely flat, with many steep slopes up and down. There are several slopes with an inclination of 45 degrees, making it very difficult for Lin Chao, who is a Tyrannosaurus rex, to climb.

So, he figured out a way to stick his sharp claws into the rock wall, and then moved his body to climb, and successfully passed the slopes.

Lin Chao originally thought that this passage was not very long, but when he arrived here, he found that the length of the passage was longer than he imagined, and in the end, he didn't know where it would lead.

"Hiss"

At this moment, a small insect chirp was heard from the depths of the passage.

Then the insects in the passage grew louder and louder, and something seemed to be moving rapidly towards him.

"Something is coming. ”

In the dark passage, a whip-like black tentacle "snapped" and whipped over, Lin Chao dodged back, and this powerful force was pumped on the rock wall, directly leaving a deep whip mark on it.

After missing the blow, the monster hidden in the darkness seemed to sense that the opponent was difficult, and instead of continuing to attack, it quickly retreated. Lin Chao immediately pounced, and his sharp claws slashed down like a razor.

The cold light was shining, and one of the tentacles of the insect was cut off by Lin Chao's claw, and green mucus splattered from the wound.

The roar of insects like a fierce beast echoed in the passage, and when Lin Chao rushed up, he finally saw the true appearance of this giant insect.

This giant insect looks a lot like the water centipede on Earth, but it is much larger, with two long tentacles like whips on its head covered in black carapace, and a giant claw like a sharp scythe around its mouth, which can easily dig through hard rock.

At the tail of the giant worm, there is also a sharp stinger, which looks very creepy.

A foul smell emanated from the giant worm, which was so poisonous that even a mammoth would be poisoned if it was pierced by its stinger.

Judging from the terrifying aura exuded from this bug, it should be a powerful creature that has evolved to the first order, and its strength is even stronger than that of the Spider Empress.

However, at this time, it was impossible for Lin Chao to retreat. As soon as he turned to run away, he would immediately be violently attacked by this bug. And in the passage with complicated terrain, it is impossible for him to run past the insects.

When the narrow road meets, the brave wins, and Lin Chao may not be afraid of this bug.

The insect that had its tentacles cut off by Lin Chao seemed to be out of anger, and its poisonous tail pierced like a poisonous snake that chose to devour people.

In the dark passage, Lin Chao had no way to dodge at all, he could only resist the attack of the insects, and he could not be pierced by its stinger, and the situation suddenly became very dangerous.

"Die, bugs!"

Sharp claws slashed across the rock wall, erupting in a barrage of sparks.

Ten meters away, in a blink of an eye.

The insect that had been living in a dark and damp environment seemed to be frightened by the sudden appearance of the spark, and its movements stopped for a moment, but Lin Chao caught the opportunity and chopped off its tail with one claw.

This worm was covered with a hard carapace, but it was useless to Lin Chao, and he easily chopped off its tail along with the mad stinger.

Under the severe pain, the crazy insect desperately waved its sickle-like giant claw and slashed at Lin Chao's head.

This bug's venomous claw is sharper than a steel knife, and it can easily tear ordinary beasts to pieces.

It's just that this insect's "knife technique" is not very good, it is simply chopping indiscriminately, and there is no discipline at all. The speed is not very fast, and Lin Chao's perception can completely keep up.

Boom!

Lin Chao crossed his claws to block the sharp claws of the insect, and then used the weight of his whole body to press on the insect.

The powerful force crushed over the insect like a bulldozer, and there was a crisp sound of "rattle, rattle" from the bug's body, and the hard carapace was cracked inch by inch.

Although this insect was huge, its strength was completely inferior to the Tyrannosaurus Rex, which was known as the strongest predator on land, and was directly crushed by Lin Chao with his strength.

At this point, the bug finally realized that something was wrong and let out a painful scream, but it was a little too late to escape.

The indestructible claws pierced deeply into the insect's head, and Lin Chao slashed violently, directly cutting off half of the insect's head.

A splash of green liquid splattered out, and the fishy smell permeated the passage, disgusting.

The worm that had its head cut off twitched a few times, and finally collapsed, completely dead.

After killing the bug, Lin Chao pulled twice on its corpse and found a black worm core as hard as diamond from inside.

"Successfully absorb the Evolution Nucleus (LV1) to gain 5 Evolution Points, 2 Strength, and 5 Free Attribute Points. ”

The system prompt appeared in Lin Chao's mind, and after absorbing the energy in the evolution worm core, his evolution point reached 88 points, and it was estimated that it would not take long to evolve to a first-order overlord.

In addition, his naked strength attribute exceeded 40 points, almost reaching the level of a high-level fierce beast warrior. In this primeval forest, there are not many creatures that can pose a threat to him.

However, Lin Chao didn't take it lightly, if he accidentally encountered a hegemon-level king beast like the Titan Python, the River Giant Beast, and the Unicorn that ruled a group or a certain field, he still wouldn't be able to see enough.

After absorbing the ability to evolve the worm core, Lin Chao continued to move forward along this passage that had been carved out thousands of years ago.

The terrain in this passage is complicated, but fortunately there are no forks, and one road leads to the dark. Therefore, Lin Chao did not have to worry about getting lost in the belly of the mountain.

I don't know how long he groped in the dark passage, but a light appeared in his field of vision.

"It's finally here!"

Lin Chao's heart beat violently, and the secret of the Xi tribe was ahead.
