The way back was very peaceful, and the mutant troglodyte dragon that had been lying on the ground remained in place, but its form had changed slightly. It turned into a mass of glue, as if the skeleton inside had been dissolved by black slime, and there was nothing left.

"It is expected that after three months, these mutants will die out on their own due to the irreversible consumption of energy. The system judged.

This is why caveytides are so confident in isolating these variants, as they won't be around for long, and it seems that caveylists have gone through several of these changes.

Go through three sealed dirt walls in a row, and seal the hole under the mound again when you go back to prevent the monsters from getting in.

In front of me was the mound of earth that I had first passed, but the entrance to the cave was blocked. It turned out to be a caveman who had found the place being dug up and re-contained a large clod of earth to block it. Of course, this was not a problem for the hairy rat, which dug up and puffed, and soon dug through the hole again.

For an hour, the hairy rat returned to the cave dragon's lair with Lin Ye in high spirits.

Sensing movement below, a caveman guarding the lair trotted over, and the hairy rat squeaked in response. Realizing that it was an old friend, the troglodyte dragon chirped happily, rubbed the hairy mouse, and returned to the main chamber.

The hairy rat is an animal that lives on the surface, and it comes to a depth of 100 meters, that is, for a small piece of natural stone.

At this moment, he returned to the lower layer of the nest safely, and the hairy rat who felt safe was holding the natural stone and rubbing it on his stomach, his eyes were full of joy. In the belly, the fetus of the hairy rat seems to sense the natural stone through the belly, and there is a slight reaction.

Lin Ye seemed to understand the reason why the hairy rat did this, maybe the natural stone was good for the unborn fetus.

However, this behavior of hairy rats is obviously not innate.

He wondered in his mind and said, "Are Cretaceous animals so smart?"

"Among the same species, the strength of adaptability obviously has a significant advantage and disadvantage difference in the survival of the species, and the improvement of intelligence is generally a positive bonus to the adaptability of the species. ”

The meaning of this sentence of the system translates to that those who are not smart are burped, and those who remain are smart. Of course, there are certain exceptions, and the smarter some creatures are, the faster they die. That's an afterword.

——————————

The main quest has been completed, and Lin Ye has also had a bumper harvest.

There was only a little more than an hour left before the equipment was successfully built, and Lin Ye's heart was full of anticipation, not knowing what would be created.

Now that he had completed the task of the underground cave, Lin Ye raised his head, nostalgic for the warm sunshine on the surface. It's dark and cold here, and it's really uncomfortable.

At this moment, the main chamber above his head began to stir again. Three or two cave dragons returned to their nests, all of them looking depressed and depressed.

The mouths of these cave dragons are dry and their tongues are cracked, and the scales on the epidermis are dry and dull.

They lack water, and the original source of water is the underground lake, and the cool groundwater is sweet and cold, and it is very delicious. However, because of a recent incident, they had to abandon it.

Oh yes, there's a mutated caveman dragon out there!

Lin Ye suddenly remembered. His complexion gradually changed, speaking of which, the mutant cave dragon should have been sealed in the passage, but now it was because Lin Ye was lured out and crashed into the mound that stopped it.

At this moment, the mutant troglodysaurus must be guarding the entrance to the underground cavern, devouring everything that can be touched.

Lin Ye looked at the cave dwelling dragon beside him with some weakness. The accident started because of him.

Originally, Lin Ye wanted to forget about it, but he suddenly remembered the silver-scaled fish in the underground lake, these silver-scaled fish, at least there were hundreds, which could provide Lin Ye with a lot of growth value, but now they were occupied by that mutated cave dragon.

This can't be endured!If these silver-scaled fish were all devoured by the mutant cave dragon, Lin Ye would have to skin them alive! Lin Ye's heart immediately burst into anger!

Gotta get rid of it!

Just do it, Lin Ye has already made a decision to deal with it. This time, Lin Ye was able to make sufficient preparations, but it was different when he suddenly encountered the mutant cave dragon before! Moreover, Lin Ye also had a secret killing move brewing, which would soon take shape.

For the sake of growth value!" Lin Ye shouted in his heart, his eyes narrowed, flashing with a sharp light.

"Let's see if the caveman has any experience in dealing with these monsters~"

He raised his head and bounced at the caveworms, putting on a super-ferocious look, suggesting that he was going to deal with the mutated caveworms.

The body language is generally simple and easy to understand, and under Lin Ye's hands and dances, the cave dragon quickly understood what Lin Ye meant.

It pulled out a chubby, white, chubby tree root the size of a forest night from the food storage room, indicating that it could be used to deal with the caveman.

How can a tree root deal with them? Lin Ye tilted his head a little incomprehensibly, but still accepted the root.

He walked towards the way back, and the two troglodytes saw him off hundreds of meters all the way, and then reluctantly called a few times.

He remembered clearly that with the help of the system, the explored area in his mind formed a complete map, which was clearly presented in front of Lin Ye's eyes.

To Lin Ye's surprise, the hairy rat also moved his little short legs, holding the fragments of natural stones, and followed him honestly.

When Lin Ye stopped, the hairy mouse stopped, and when Lin Ye walked, the hairy mouse followed.

It was no longer afraid of Lin Ye, and its big shining eyes were full of worship for Lin Ye. The hairy rat was originally a kind of rat that was placed under the fence of the strong, and now it uses Lin Ye as its shelter.

Go farther!

Lin Ye can't shelter it, he's not a refugee shelter. Besides, he is now going to deal with the mutant cave dragon, and the hairy rat will be in danger of his life if he follows him.

Now explain to the hairy mouse, it also does not understand. Lin Ye was ruthless, flapped his wings, and his running speed increased.

But the hairy mouse didn't understand why Lin Ye wanted to shake it off, and it ran quickly, like a gray fluffy ball rolling on the ground. Although the hairy mouse tried so hard to keep up with Lin Ye's footsteps, he was still hung far behind by Lin Ye.

"Squeak~" The voice of the hairy mouse became farther and farther away, and it was soon left behind, and it was inaudible.

Hearing the sound of the hairy mouse, Lin Ye sighed in his heart. He certainly won't abandon the hairy mouse. Seeing that the hairy rat wanted to follow him, Lin Ye actually had a set of plans to place the hairy rat in his heart at that time. But this is all until the mutant troglodyne is killed.

——————————

"Drop! The crafting prop has been formed and identified as E-class equipment. [Double-headed Meteor Bone Hammer]. ”

Lin Ye walked along the tunnel, quickly approaching the underground cave. And the new equipment created was successfully released at this time!

A white light flashed, and Lin Ye had a new piece of equipment in front of him.

These are two bone joints that have been fused together, and there is a groove in the middle that joins together, and a slender but tough thread is wrapped around the groove, which is more than a meter long. It seems to be able to pick it up and shake it. But it looked like two bone joints were stacked together, and Lin Ye couldn't see anything special at all.

This is a weapon that is used by holding the end of the rope and swinging it vigorously, using inertia to attack the enemy in front of it.

Yo-yo? Lin Ye was stunned for a moment, instinctively thinking of this term.

"It's a meteor hammer. The system corrected Lin Ye's idea and gave an evaluation of the weapon, "According to the inference, the damage caused by the two-skull hammer under the full swing of the host is equal to the host's raptor kick, and it has a powerful [Armor Shattering] effect. ”

"Due to the lack of natural breath, the Meteor Bone Hammer produced is the lowest level, Class E. ”

However, this is also enough, it is exactly the long-range strike method that Lin Ye needs! It is more secure to deal with the mutant cave dragon.

Lin Ye dragged the [Double-headed Meteor Bone Hammer] on the ground with a long line in his mouth, sandwiched the roots under his wings, and continued to move forward in small steps!

The goal, kill the mutant troglodyne!
