Zhu Jianhai was already desperate, knowing that he would definitely die, but he was no longer afraid, and the timid behavior just now disappeared.

"What do you mean, these slippery cave walls are left behind by that monster?"

Lin Song couldn't believe his ears, such a long cave, at first he thought it was a tunnel dug by Zhu Jianhai and them, but now it has actually become a monster's cave.

"That's right, that monster may not believe it, it's a new species created by this base."

Zhu Jianhai looked at a black shadow, which gradually projected over, and had gradually covered half of Zhu Jianhai's body.

"He's here, run Zhu Jianhai."

Lin Song didn't want Zhu Jianhai to receive the lunch box in advance, it was useful to keep him, but no matter how hard Lin Song tried, Zhu Jianhai was like being filled with lead, and he couldn't help him.

"Don't bother, I'm going to die, because I'm immobilized by him."

Zhu Jianhai lowered his head as he spoke, looking at his immobilized feet.

Lin Song saw that along the direction of the tunnel cave, something like a spur several meters long had drilled out from under the ground, forming an X-shaped iron pincer-like thing, firmly fixing Zhu Jianhai's feet on the ground, making it difficult for him to move an inch.

"It's man-made."

Lin Song didn't believe in evil, grabbed that thing with both hands, and wanted to break it, but Lin Song used his strength to feed, and didn't move that thing at all.

Sweat was rolling down his sideburns like rain.

"Hehe, brother, don't work in vain, I'm going to die, the only thing I can't let go of is my brother's fourth, promise me to take my brother out."

As Zhu Jianhai spoke, he pulled out a dagger from his waist, and the sharp edge flickered from time to time.

"What are you doing here?"

What Lin Song didn't expect was that Zhu Jianhai actually ripped off his shirt and slashed at his chest with a sharp dagger.

A line of hot blood rolled out of the wound, and it was still steaming white.

"I have carved the tunnel of escaping from the base on my chest in advance, you can take this layer of skin on my body, you can take my brother home, I promised my mother to bring my brother back."

Zhu Jianhai endured the severe pain and tore off the flesh on his chest.

When Lin Song took the bloody human skin, he didn't know how to express his gratitude.

Although Zhu Jianhai has selfish intentions, being able to make such a sacrifice before dying shows that Zhu Jianhai is by no means beyond the reach of ordinary people.

"Lao Zhu, don't worry, I promise you."

Lin Song gently closed Zhu Jianhai's eyelids that he hadn't closed, he knew that Zhu Jianhai couldn't rest assured that the brother who was no longer a human being.

However, Lin Song had no time at this time, and Zhu Jianhai didn't say much about that monster, but just told Lin Song that it was a new species developed by the base.

Just when Zhu Jianhai closed his eyes, the ground thorns that fixed Zhu Jianhai were like magic, and suddenly disappeared, and all of them were sucked into the ground.

Then the huge rumble came again, and it seemed that this monster could not move when it released the ground thorn, and now it retracted the ground thorn, so it started a new movement again.

Zhu Jianhai's body collapsed there, and Lin Song couldn't take care of Zhu Jianhai anymore, so he could only retreat in the opposite direction of the monster alone.

After all, he hadn't seen that monster with his own eyes, and Lin Song was unwilling, so after feeling that he was at a safe distance, Lin Song secretly observed what was about to happen.

The black projection became larger and larger, and a monster that Lin Song had never seen before appeared next to Zhu Jianhai's corpse.

Lin Song, who has been hunting for a living since he was a child, has never seen this kind of monster, which shows that the appearance of the monster is really different.

It looks like the monster has the head of a cow, but it has a mouth like a tiger, and the fangs are like those of a shark, showing a jagged arrangement, and there are no fangs like a tiger's square ruler.

This appearance alone does not conform to the principle of biological evolution, which is clearly a complex of marine and terrestrial organisms.

Looking at the monster's body again, it is simply a manic Tyrannosaurus rex in the world, showing two hind legs walking upright, and a huge tail balancing the body.

The monster was like smelling a gluttonous feast, and accurately found Zhu Jianhai's body, as if he had been hungry for several months, opened his bloody mouth, tore Zhu Jianhai's whole person to pieces, and chewed Zhu Jianhai into minced meat in less than a minute.

After eating Zhu Jianhai, the monster seemed to be unsatisfied, wandered around for a while, and returned the same way.

When the monster returned, he rubbed his huge smooth body on the cave wall from time to time, making the already smooth cave wall even smoother.

Lin Song unfolded the flesh cut by Zhu Jianhai, looked at the tattoo on it, and knew where the monster's lair was.

Why did the enemy create such a strange species?

Lin Song didn't know the specific reason yet, but the tattoo clearly told Lin Song that if he wanted to capture the enemy's base, he had to first uproot the monster's lair.

Because the Lair is the only way to base command, there is no other choice.

Lin Song quietly pursued the fourth child, he had to be cautious, with his current strength, he would definitely not be able to deal with that monster.

'Bang, bang, bang. ’

Lin Song felt that he was about to arrive at Fax's laboratory, and he heard a sound of banging.

It must have been the fourth child trying to push open the manhole cover that connected the underground tunnel to the surface lab.

When Lin Song rushed over, the fourth child was still working hard, he glanced back at Lin Song, but he didn't see anything at that time, as if Lin Song was air, not a big living person.

"The fourth is enough, your brother has already hung up for you."

Lin Song wanted to get the fourth child to stop this senseless behavior, with the fourth child's perverted SSSSSS-level evolutionary ability, he couldn't get the manhole cover made of alloy, and Lin Song couldn't open it.

"Roar, I want to live, I want to change back."

The fourth child said unwillingly, his hands still trying to push open the alloy manhole cover.

"Your brother will tell us how to get in."

Lin Song saw that the fourth child was screwed to death, and it was difficult to convince him, so he decided to help him, since Lin Song had agreed to Zhu Jianhai's request, then he would do his best to the end, unless the will of heaven did not leave the fourth child, Lin Song would definitely save the fourth child.

"Brother."

When the fourth child saw that Lin Song actually took out Zhu Jianhai's flesh, he roared, and with a crisp click, the manhole cover was pushed open.
