With a snort, Lin Ye wiped out more than half of the hundreds of silver-scaled fish at the bottom of the lake in one go, and gave Lin Ye more than 200 points of growth value in one fell swoop, making his growth value soar to 630 points, just 100 points more than the natural breath he had.

With a full burp, Lin Ye's stomach swelled round, his digestion ability was top-notch, but each silver-scaled fish could only take a bite to absorb the growth value inside. Of course, Lin Ye left a few silver-scaled fish as fish species, these silver-scaled fish will not produce natural breath, and the fish larvae they give birth to will naturally not have natural breath.

There's nothing left to be nostalgic about.

Returning to the cave dragon's lair, the cave dragon that gave Lin Ye the root of the tree sensed Lin Ye and screamed in surprise. It smelled the scent of the enemy from Lin Ye's body, and now that Lin Ye came back alive, it means that the matter has been successfully resolved!

After knowing that Lin Ye had eliminated the mutant cave dragon, the cave dragons present cheered one after another, and they lifted Lin Ye high and threw Lin Ye up and down excitedly. More than half of the troglodyte dragons licked their dry mouths and couldn't wait to head towards the underground lake. The other caveworms tended to their cubs, waiting for their companions to bring back the water.

The smooth flow of underground lakes means that they don't have to travel long distances and spend more time traveling to extremely distant water sources.

In the corner of the main chamber, however, the hairy rat sat on the ground with some frustration, holding a small piece of natural stone in its arms. Its purpose had been accomplished, but it was sluggish, leaning against the wall, staring blankly.

The troglodyte dragon's cheers did not alarm it.

As a creature under the dragon's hedge, the mate of the hairy rat was killed by the mutant troglodyte a few days ago. The underground environment became extremely hostile to it in an instant, and in addition to the mutated troglodging dragons, there were also many carnivores lurking.

And it is strong and hard to survive in a dangerous environment, and looks forward to using natural stone fragments to make its descendants stronger. However, it can survive on its own, but with a dozen or so children born, it is not so easy to survive.

Just when it was in despair, the black-winged chick walked up to it and stretched out a wing at it.

Would you like to come with me?" Lin Ye looked at the hairy rat, stretched out his wings, and invited it to his territory. His realm really lacked some assistants.

Lin Ye's kindness immediately impressed the hairy mouse.

After discovering that Lin Ye had not abandoned it, the hairy rat trembled with excitement.

At this moment, seeing Lin Ye sending an invitation to it, it was like seeing a savior, the hairy mouse was half-lying on the ground, squeaking excitedly, and expressing obedience to Lin Ye. At the same time, it also made several body movements, colliding with fangs, waving its nails, trying to prove that it has a lot of use for Lin Ye, such as you can bring it to fight!

It's not a parasite. It can help Lin Ye defend against foreign enemies, and it can also be sentry, and it can even be used as a bait to seduce enemies!

Lin Ye didn't expect that this small move of his own would bring new hope to this hairy mouse. He stretched out his wings and patted the hairy mouse lightly, calm down!

Only then did the hairy rat calm down and be excited.

"Seeing that you have gray fur, you will be called Little Ash. ”

Lin Ye decided to name it Little Ash.

Grey the mouse, join the shallow waters!

As the hairy rat joins Lin Ye's camp, the system shows the attributes of Little Ash.

"Hairy Mouse: Little Gray, a low-level intelligent creature with low strength, low physical strength, poor physical fitness, and a timid personality. Loyal, fecund, good at digging. She is two weeks pregnant and is expected to give birth in a week. ”

Looking at Ash's attributes, there don't seem to be any advantages worth mentioning. But what Lin Ye likes is the wisdom that Xiao Ash has! No matter how many weaknesses there are, how inferior his physique is, as long as he is smart, he can make up for the above disadvantages!

With a little training, the hairy rat can help Lin Ye take care of a lot of things. Taking care of the growth of rice paddies, cutting grass and feeding silverfish, as well as building roads and giving early warnings, all require "human" hands. And this is also the reason why Lin Ye took in hairy rats, because they are born quickly and smart, and they can quickly form a labor force.

The caveworms had already returned from fetching water, and they were lying on the ground drinking with a naturally formed wooden scoop in their mouths. After meeting Lin Ye, their knowledge has also increased a lot, and they have become closer to Lin Ye. They knew that Lin Ye had come from the outlet at the top of the underground lake, and they discussed it, and seemed to reach a consensus. Lin Ye didn't know what they were communicating.

At this point, the main quest has been completed, and Lin Ye has discovered two biomes, one of which is a cave dragon, and the other is a hairy rat, and the latter is subordinate to Lin Ye and has become Lin Ye's vassal.

Wait, how do I bring the hairy rat up?

After being taken in by Lin Ye, the hairy mouse happily followed behind Lin Ye, and when Lin Ye walked through a fork in the road and was about to turn right, Lin Ye suddenly thought of this key question, and was immediately stunned in place.

The rope more than thirty meters long was washed by the heavy waterfall, Lin Ye gritted his teeth and could climb up against the waterfall, but with a hairy mouse, it was not so easy.

Just when he was at a loss, the hairy rat stretched out its little paw and pulled Lin Ye, as if to tell Lin Ye that it knew a shortcut back to the surface.

Lin Ye turned his head and followed behind the hairy mouse, walking towards the passage that he had not walked through.

One hour, two hours, three hours......

Under the leadership of the hairy mouse, Lin Ye walked along the labyrinth dug by the cave dragon, although the overall terrain was very sloping, it had been winding upward, and the passage became narrower and narrower.

Time flies, and the road ahead is still far away.

Finally, Lin Ye saw a faint light coming out from the front.

Squinting his eyes, the light that gradually became intense as he got closer was a stimulus to Lin Ye's eyes.

I never expected that after walking up, the scene in front of me was so familiar!

Fresh air is coming!

Turning around, Lin Ye actually returned to the underground waterway where the bird-catching spider had been killed, and at this moment the hairy rat was drilling out of the exit of the underground waterway, and it stepped on the dilapidated and rotten cobweb, and squeaked happily at Lin Ye.

After killing the bird-catching spider, Lin Ye did not continue to explore. On the right, near the shore of the Blood Moon Lake, the pale red water of the lake is undulating, and the faint waves crash against the entrance of the waterway. At a depth of five meters inside the cave entrance, it was the exit where Lin Ye and the hairy rat were. On the left, fifty meters deep, near the corner, is where Lin Ye killed the bird catcher spider.

After the birdcatcher dies, the hairy rat is able to regain the path out of the ground without being attacked by the bird's spider.

It was obviously a battle between Lin Ye and the bird catcher, but it has affected it until now. Lin Ye's mood was accompanied by the rippling water of the lake, and he deeply understood what cause and effect was. With the reason why he killed the bird catcher, there was the fruit of the hairy rat who brought him here.

At the edge of the cave there are traces of dinosaur eggs accumulating. Those cave-dwellers laid their dinosaur eggs here and were exposed to the moonlight. And this is the second source of water for cave dragons.

They are subterranean creatures and have no eyes. At the same time, because of the long distance and the underground lake as a water source, cavemen rarely come here except during the breeding season.
