The yellow-faced and thin-skinned caveman swallowed the food brought by Lin Ye in a big gulp, they had never eaten such a delicious thing, they all admired Lin Ye so much, even the old cave dragon that had not joined the shelter area couldn't help himself with excitement after eating the food brought by Lin Ye.

The passage that once led to the caveworm's lair was once again sealed, and the dozens of troglodytes that were missing were blocked inside, and these cavemen had completely undergone extreme mutations. Lin Ye ordered the caveman to stand by in the underground cave, and he personally went to the caveman lair to kill the dozens of mutated cavemen.

Pushing away the blocked stones in the passage, Lin Ye took a deep breath and took a step forward, while ordering the caveman behind him to block the underground passage again, and it could not be opened until he came out.

The wind whined overhead, and the sound of the caveman behind him had completely disappeared. Lin Ye wrinkled forward two hundred meters away, and according to the memories in his mind before, he walked towards the cave dragon's lair step by step.

In addition to killing all the mutant troglodytes, Lin Ye also had to find the mine that the original troglodyte dragon had dug up, and take out the remaining natural stones to use as materials for creating the phoenix totem.

The ground beneath Lin Ye's feet began to appear radiating black spots, which were a sign of the appearance of mutated creatures, and these black spots were still very wet, so it seemed that the enemy was nearby.

The flames surrounded Lin Ye, forming a distinct flame shield that could help Lin Ye resist sudden attacks. The red flame also has a characteristic, that is, it can illuminate the road ahead, although Lin Ye has night vision, but also prefers to move in places with bright lights.

Although this will continue to consume Lin Ye's mental power, Lin Ye's spirit is still very sober, and after becoming a juvenile, Lin Ye's spirit has also increased significantly. With this level of mental consumption alone, Lin Ye could hold on for six hours, which was completely able to support him for one round trip.

Occasionally, a wet, viscous black liquid drips from the rock wall overhead.

The entire underground passage was extremely long, there was not a single insect, and there was no sound of any living creatures, even if a needle fell on the ground hundreds of meters away, it would be clearly heard by Lin Ye. It's like an abandoned mine, with intricate, dead, lifeless tunnels. But there is no doubt that there are dozens of cave-dwelling dragons that have undergone extreme mutations, hiding in every corner, and they may come out to attack Lin Ye at any time.

Click~

Heavy wheezing came from three hundred meters ahead.

Wandering ahead were three unconscious troglodytes, their bodies completely transformed into black "oil", devouring any visible light. One of the closest mutant cave dragons spotted Lin Ye in front of him, and it let out a heavy breathing sound, slowly turned around, and rushed towards Lin Ye.

It is not afraid of death, it does not know what pain is, but according to instinct, it seeks the emptiness in its body, and wants to fill it completely. It's like a corpse that has lost its soul, hoping to kill and assimilate other creatures to get it. But eventually, the creatures it assimilated into flesh and blood in its body, becoming part of the corpse.

Lin Ye was naturally merciless to these cave dragons who had lost their biological consciousness, and he controlled the flames to form a three-meter-high wall of fire directly in front of them.

The ferocious wall of fire filled the entire passage in an instant, and under Lin Ye's control, it quickly advanced forward. The three mutant troglodmen were directly engulfed in flames, their flesh turned to ashes, and their pitch-black bodily fluids were burned into steam. In the end, only three white shifts were left on the ground, which were the ashes of the bones in their bodies that had not yet been completely dissolved.

There are also a few cave dragons that have been completely mutated and have turned into a mass of "slime monsters", they have lost their mobility, and there are traces of their movements on the top of their heads, under their feet, and on the left and right sides.

Tick!

There was a wet liquid dripping from the top of his head, and when Lin Ye raised his head, he saw a sticky mass of glue on the top of his head, like a lump of thin black mud pasted on the top.

The air suddenly became very humid in an instant, and a faint smell of blood could be smelled, Lin Ye waved his wings, and burned all the black "thin mud" he encountered along the way into ashes with flames.

He continued on, and soon came to the caveman lair.

The caveman's lair was surrounded by black slime, flesh and blood that had mutated into the dragon's body, but the shape of the creature was no longer recognizable.

Before, there was a hairy mouse Xiao Gray to lead the way for him, but Lin Ye was not very afraid. And now, except for Lin Ye, a bird staying in the dark and silent passage, there is not a single living thing within a radius of hundreds of meters.

The entrance to the lair is blocked by rubble, while the passage to the upper and lower levels of the main chamber is similarly sealed with stone and earth. This is what the caveman dragons who have not yet lost their consciousness do, and they have sealed their companions who have completely mutated in their lair, which gives Lin Ye great convenience.

In the room on the upper level of the lair, as long as it is blocked by earth and stone, there will be a mutated caveman dragon or even an upward mutated troglodyne.

Lin Ye used his wings to pluck away these black netted stickies, break these earth and stone seals, and clear the mutated cave dragons in the room one by one, while looking for anything missing.

A ......

Two ......

Three ......

Every time Lin Ye used flames to purify a mutated cave dragon in the room, he would write down a number in his mind. By the time he slammed open the mound of earth and rocks in the door of the last nursery, the number had risen to twelve.

The scene in the nursery room was beyond Lin Ye's imagination.

"Is this one, or is it eight?" Lin Ye took a deep breath and stood at the door of the nursery, he looked at a monster in front of him, and said to himself in his heart.

It was a room completely covered in black glue, like a fungus blanket.

In the nursery, eight extremely mutated cave dragon cubs have been fused together, their heads spliced together, and the eight young heads are crammed into a fat neck, and the eyes are empty, forming a strangely shaped monster.

Originally, seeing such a monster in a dark underground secret room would have made anyone very frightened. But Lin Ye was already used to it, and his heart was indeed touched, but he could still remain calm. On the contrary, it was the things behind this monster that made Lin Ye interested.

On the pitch-black ground behind the monster, there was an equally pitch-black eyeball, which was turning around and staring at Lin Ye at this moment.

It is a first-class eyeworm, Lin Ye flapped his wings, not surprised. The eyeworm was an important source of his growth value!And the moment the eyeworm saw Lin Ye, especially after seeing the flames around Lin Ye, its eyes were immediately filled with fear, as if it had met a natural enemy.

The first-level euglena did not have any threatening ability to creature beings, and its eyes widened to scare Lin Ye away. But after Lin Ye learned about them, he was no longer afraid of them.

The eyeballs that originally frightened others became the frightened party. At this time, the monster made of eight cubs found Lin Ye at the door, and immediately roared and pounced on Lin Ye.
