At this moment, in front of Lin Ye, it was a storage room of the cave dragon, and three shiny natural stones were placed in it!

Why did he choose to come to the underground cave, Lin Ye also had a purpose, that is, to verify an idea in his heart. And now his idea has been confirmed.

The natural stone that contains the natural breath is indeed a kind of ore.

Natural stones will not fall from the sky, Lin Ye knows this very well, he went down to the underground cave this time, in addition to the accident according to the main quest, it is also to find the natural stone.

And these cavemen have natural stones!

The birth of intelligent creatures is full of difficulties and dangers, and it will never appear as easily, unless it is assisted by the breath of nature, otherwise even if millions of years have passed, the probability of its appearance is very small. And now just in the vicinity of the Blood Moon Lake, Lin Ye saw the rudiments of several intelligent creatures. And he has witnessed Redback go from a goofy lizard to a smart and clever one.

All of this is derived from the breath of nature, in other words, from natural stones!

The conjecture had been confirmed, and Lin Ye understood what the meaning of the main quest released by the system for him was.

He walked into the storage room, his eyes lit up, these three natural stones didn't know how much natural breath they could provide him, of course, it was definitely enough to create a suitable equipment or props!

But then Lin Ye stopped, these natural stones should be the treasure of the cave dragon, so let's wait and see for the time being. If the natural stone in the storage room suddenly disappeared, even if the cave dragon was a fool, he would know that only Lin Ye could do this.

He swaggered back to the main chamber and greeted a caveman who was resting with its legs nearby. Lin Ye raised his wings and pointed at the natural stone placed in the room, and the guarding cave dragon suddenly raised its head and screamed after noticing Lin Ye's movements.

Judging from its attitude, Ga, which means denial. It rejected Lin Ye's offer.

Sure enough, no. These natural stones should be something useful for cavemen. Lin Ye thought in his heart that when he saw that he was rejected, he suddenly had an evil thought and had the idea of snatching. But then he shook his head, in the long run, it was still necessary to have a good relationship with the caveman, and besides, he was not the kind of bird who did all kinds of evil.

For example, can you make a deal? Lin Ye had a good idea in his mind. He thought to himself, these cave dragons must have never eaten cooked food, as long as they exchanged cooked food, they might be able to get these natural stones! And if they continued to trade like this, they might be able to earn even more!

If they don't eat cooked food, Lin Ye also has many ways! Insects are fighting, silver scale fish sashimi, herb tree roots are boiled, Lin Ye will do it, this is Lin Ye's proud work.

With this in Lin Ye's mind, an adult caveman dragon suddenly ran in at the exit outside the main door. Its paws hold many white and tender roots, and at the same time it has many underground mushrooms in its mouth.

The troglodyte placed its food on the ground, and several hungry cubs gathered around, delightfully swallowing and chewing.

Adult cavemen go out foraging for food and bring food back to their cubs. When Lin Ye was exploring the cave dragon's lair, this kind of thing had happened several times.

But this time it's a little different. Lin Ye raised his head, and he felt that there was something strange about the movements of this adult cave dragon.

There was some black viscous liquid adhered to the back of this caveman, and there was a big palm***** Julong looked very sluggish, his hands drooped, and he hummed in pain. After placing the food on the floor, it tried to rub its back against the wall, but the black liquid on its back spread as a result, increasing the surface area covered.

The viscous liquid exerts a deeper irritation on it because of its movements. The caveman screamed in pain again, terrified. It fell to the ground in agony, its thick legs stretched out to support its weight, and the viscous liquid on its back seemed to entangle the caveman in pain.

"Is it sick?" Lin Ye stood aside, he looked at the black liquid on the back of the cave dragon, and always felt as if he had seen it somewhere.

Beside it, six adult troglodytes distanced themselves from it, and they let out a sad cry, two of which bit its tail and slowly dragged it out of the main chamber. And the caveman that was dragged away also cooperated and crawled out little by little, and seemed unwilling to transmit the disease to its companions.

Seeing that they were going to take this painful cave dragon to an unknown place, Lin Ye jumped out.

He sensed it might be time for him to help. These cavemen could not see the black liquid on their companion's back, and the latter had no scent, nor could they smell it. But Lin Ye saw it clearly, and knew that the black liquid on his back was the culprit that caused the caveman to be weak.

"Wow!"

Lin Ye chirped, blocking the way of the cave dragons. He stepped forward, carefully observing the sticky liquid on the back of the caveman lying on its side on the ground.

This!

His eyes shrank suddenly, Lin Ye was frightened, and he suddenly took a small step back.

In its observation, the palm-sized black liquid seemed to be capable of movement, its surface glowing with a delicate oily glow, constantly wriggling, and occasionally sticking out a small black tentacle that seemed to cling to something.

Is it a parasite?

Seeing that Lin Ye was blocking their way, the cave dragons were restless, they couldn't understand what Lin Ye was trying to say, and they didn't know why Lin Ye was doing this. They continued to carry their companions, trying to ignore Lin Ye. It seems that this is not the first time they have done this, and they are rushing to isolate their infected companions, otherwise the entire population will be devastated.

Stop me!" Lin Ye shouted, inadvertently releasing a coercion, instantly shocking the six cave-dwelling dragons around him.

Lin Ye's feathers stood up, and he held his breath and stared, his gaze locked on the black liquid on the cave dragon's back.

The flame has the effect of purifying everything, although Lin Ye's flame feather coat has not yet reached this height, but it is still possible to burn this entity.

"Whatever it is, it's all going to be wiped out under the flames!" Lin Ye shouted in his heart, and the gathered flames slapped on the cave dragon's back like a dog skin plaster, covering all the black liquid!

The cavemen in the presence raised their scales, and they felt a rush of heat, accompanied by a piercing scream.

In less than a second, in the time that the caveman dragon could not react, the black liquid covered by the flames was instantly burned clean, but the moment it was touched by the flames, it actually let out a sharp chirp, echoing in the passage, lingering endlessly!

The caveman who had been treated by the flames grunted weakly, and Lin Ye's flames burned its back.

Too late to explain.

The six troglodyte dragons around them noticed that their companion had been injured by Lin Ye, and they roared angrily, spreading their legs and slashing to the ground, and immediately became hostile to Lin Ye.
