A heavy wheezing sound, with a viscous black liquid, rolled up the dust in the air and dripped onto the ground. Mysterious creatures walk through the side of a buried cavern.

Because the road he came from had been blocked, Lin Ye couldn't see the specific appearance of the mysterious creature, and he was led by the caveman along the dug tunnel in a daze.

The caveman in front of him lowered his body and walked forward cautiously, not daring to make any sound with his steps, while Lin Ye followed behind it. The mystical creature's wheezing was too far away to be heard.

Although he is petite, Lin Ye's head is still very flexible. Seeing that the cave dragon had no ill will towards him, Lin Ye was no longer worried, he lowered his head and walked silently, while beginning to connect this series of events.

Soon he came to an obvious conclusion, that is, the cave dragon saw Lin Ye purely by accident, but there was also a reason why it came here.

The system helped Lin Ye make an analysis: "According to the inference, the cave dwelling dragon dug the cave and came here for the water source of the underground lake. After judging that there was a dangerous enemy, he fled with the host. ”

It's just that it can completely let Lin Ye go, so why save him? This is obviously a sign of sympathy. After all, in the perception of the cave dragon, Lin Ye was just a skinny chick.

Lin Ye was silent and raised his head to look at the cave dragon in front of him. Suddenly, Lin Ye remembered something, and suddenly became excited.

Could it be that this caveman already has the same rudimentary wisdom as Redback?

The cave dragon let out a low roar, and after walking far enough, its steps became brisk, and at the same time, it turned its head and sniffed Lin Ye from time to time, as if it was a little happy that it had saved Lin Ye. It emerged from the tunnel and came to a very wide, underground tunnel that extended in all directions.

The smooth surface is flat and smooth, with some rough granite padding on the pavement. On either side, there are some fluorescent mushrooms that emit a shimmering glow. The tunnels are tall and wide, enough for five cave-dwelling dragons to pass side by side.

It seemed to be very interested in Lin Ye, and after coming to the wide passage, it circled around Lin Ye, and then raised its head and chirped highly. Voices echoed through the dark tunnels.

This chirp is meant to call out to its companions.

After a while, there was a sound of clattering feet from the tunnel, and a group of dinosaurs that looked like caveworms appeared in Lin Ye's sight, they had big brains and ran fast, and immediately came to the caveman's side. After seeing the cave-dwelling dragon, they jumped a few times with joy and cried out in joy.

The caveman shook his head, looked depressed, and shouted a few times at his companions, the sound was like a syllable one by one, just because its vocal organs were not yet developed, so there were only four simple quacks, ah, oh, clicks.

As the cave dragon recounted, its companions immediately lowered their heads, as if they were very lost.

During the whole process of these dinosaur exchanges, Lin Ye was in a state of confusion, tilting his head, what were they talking about? Although it was only a simple four syllables, after combining a sentence, the meaning would change dramatically.

At this moment, the system broke the tranquility in Lin Ye's mind. "Ding! Caveman social biome has been discovered!"

The troglodyte sniffed, and they lowered their heads, and immediately sensed that at the foot of the burrowing dragon, which had returned safely, there was a feathered chick standing. They were stunned.

Seeing these dinosaurs that may have rudimentary intelligence, Lin Ye will not miss the opportunity to communicate. He spread his wings and jumped onto a small rock, chirping in an attempt to communicate with the troglodyte. But the latter tilted their heads one after another, as if they didn't understand Lin Ye's reason for doing this.

Seeing this, Lin Ye took a sharp breath and knew that he had to use a ruthless move. He spread his throat and began to sing.

"Chirp~Ka~Wisp~Ya~Woo Ka~"

"Ahem~ah~card~chirp~touch!"

Lin Ye's singing voice is really bad, the first time he sang with a bird's singing voice, the songs were directly out of tune. But the cave dragons were shocked, and they sniffed Lin Ye's body in surprise, and they became more interested in Lin Ye.

Seeing that the singing was effective, Lin Ye continued to cheer himself up in his heart and continued to sing.

If the caveman had eyes at the moment, it must have been a light of surprise and excitement in both eyes, and a few of the cavemen had suddenly discovered something, and the chick seemed to be trying to communicate with them.

One of the troglodytes also sang in a low voice, and its behavior immediately aroused the resonance of the other troglodytes, and they all roared in a low voice, although there was no tacit understanding at all, and Lin Ye led the formation of a terrible choir. However, they slowly found a consensus with Lin Ye in their singing.

As cave dragons with low-level intelligence, their wisdom may not be comparable to that of even the oldest primitives, but for Lin Ye, it is already a big discovery!

Lin Ye stretched out his wings, and the cave dragon also stretched out his stubby forelimbs, and the two touched lightly, and a consensus was reached on the aspect of singing.

Soon, in a dark and secluded underground tunnel more than 100 meters above the ground, a bird and a group of burrowing dragons formed a preliminary friendship.

Welcomed and led by the cave dragons, Lin Ye was treated as a harmless existence and smoothly came to their lair.

Lin Ye happily drilled in and out of the cave dragon's lair, and after a cursory exploration, he immediately had a diagram of the structure of the nest in his mind.

There were fifty or sixty burrowing dragons in total, and more than twenty cubs.

The nest is divided into three rooms, connected by excavated tunnels.

The top floor has more than thirty small rooms and two large rooms.

The children born to the troglodyte were raised by the group, and the small room was where the adult troglodyte slept, and a large room was the nursery for the cubs, and next to it was another large room where delicious roots, mushrooms, insects and other food were stored.

The middle floor is divided into two rooms, one is the main room, and the other is the egg hatching room, which must pass through the main room to get to the egg hatching room, and there are usually two cave dragons guarding here.

Lin Ye is now in the middle of the main room, there is a lot of space here, it is a place for the cave dragons to communicate, used to cultivate feelings for each other, the main room is connected to the upper and lower floors, if you want to reach the other rooms, you must pass through the main room.

The main chamber is also the exit from the lair, and the exit is connected to a wide tunnel that extends in all directions, which is where Lin Ye came, and there is no end in sight, and I don't know how deep it has been dug.

"Ding! Main quest completed! Please be patient and wait for the follow-up main quest. ”

"Cavemen lacked the necessary eyesight, the population was too small, and it was a primary society, with almost zero potential for improvement in the social system. After the task was completed, it seemed that through Lin Ye's observation, he gave an evaluation of the Caveman Dragon Society.

Lin Ye went down to the bottom, there was a fork in the road, and the road on the right was blocked by gravel and dirt, so Lin Ye went to the left and passed a room.

It was just a casual glance, and at this glance, Lin Ye suddenly took a cool breath, and his eyes widened.

In the room lie three natural stones, these natural stones glow yellow and contain a strong natural atmosphere!
