'Da, da, da. ’

The three of them walked shoulder to shoulder, foot to foot, slowly walking down the empty underground laboratory, the further down they went, the darker the basement laboratory became, the light seemed to be scared away by something more terrible than the darkness, and it seemed that they did not want to come to this strange place.

"Does it feel like it's getting emptier in here?"

Ye Bai looked at the environment in the dark, there were only a few cement pillars supporting the basement in the night vision glasses, and he couldn't see the edge of the underground laboratory at the end of his sight, and he could see the edge of the laboratory when he just came down, and silently calculated the sound of footsteps in his heart.

"Well, it's true that this basement is getting bigger."

Cao Xiaoseng followed the footsteps of the medicine spirit, and the special radiation-resistant hard-soled shoes kept making a 'da, da' sound.

In fact, when they first went down to the basement, the footsteps were relatively close to them, and the reflection time of the sound was relatively short, so they could not hear the second echo at all, and the sound was relatively crisp; But in the open space, it is different, every time you take a step forward, the footsteps will be relatively dull, after the first footsteps have passed, Cao Xiaoseng can clearly hear another echo after a while.

Cao Xiaoseng judged the size of the basement based on the crispness of the footsteps and whether there was an echo.

"Something!"

The medicine spirit between Ye Bai and Cao Xiaoseng suddenly turned around and walked towards the other, and the pulse gun in his hand pointed directly at the place he was looking at just now.

Ye Bai didn't hold the knife The power of the fire attribute in his left hand was directly condensed, illuminating this piece of basement, it was the corner of the basement, and there was a green elixir on the wall at the corner that I didn't know what the name had been broken, like a small green handprint on it.

"What's going on? Ling'er. ”

Ye Bai asked what the medicine spirit had discovered, there was no need to hide it now, the voice of the medicine spirit just now and the basement illuminated by the power of Ye Baihuo's attribute had already exposed their location, or it was possible that it had been exposed as soon as they stepped into this villa area.

The praying mantis catches the cicada, and the yellow finch is behind. During this time period and in this environment, the identity of the prey and the hunter seems to have changed inexplicably.

"Huh?" Yao Ling walked over and took a closer look at the corner of the basement, found that there was nothing, turned around and said, "I don't know, it's nothing, I obviously felt something just now." ”

Yao Ling frowned, turned around and looked again, and only after confirming that there was nothing before returning to the team.

"Ling'er, don't do this next time." Ye Bai and Cao Xiaoseng walked towards the position of the medicine spirit, asking the medicine spirit to return to the team quickly, Ye Bai continued: "Don't leave the team without permission, especially in this dark environment, don't leave the team easily, be careful to turn the tiger away from the mountain, if you disappear in this place, it will not be easy to find you." ”

"Oh." Yao Ling bowed his head and admitted his mistake.

"Ye Bai, do you feel that this place is getting more and more wrong." Now in this situation, no one who can sleep will not feel sleepy, Cao Xiaoseng is unusually awake now, he doesn't remember the last time he was so awake was when he was eight or nine years old, I remember that it was him who was about the same situation, if it wasn't for his father coming in time, maybe he wouldn't be there now.

Ye Bai turned his head to look at the medicine spirit and confirmed that she had returned, before he said: "Well, the further down you go, the more red and green potion traces there are on the wall, it is supposed that something should come out, but nothing has been found so far, it is not normal." ”

Ye Bai led the way and continued to walk down, there was no turning back when he opened the bow, there was no turning back, and he couldn't say that the way back had become more dangerous.

"And the basement is also quiet, it feels like no one exists, even the sound of breathing is just the three of us. By the way, Ling'er, what did you see just now? ”

Yao Ling lifted the night vision goggles on his eyes, and the black on the side of his eyes turned green again, "It seems to be a relatively small thing, a little like a mouse before the Dark Age." Yao Ling said with some uncertainty.

"Mouse?" Ye Bai asked rhetorically, a little surprised, after entering the Dark Age, the mice have become bigger than cats, and they basically survive in the Shenmu Mountain Range.

The three of them walked down a few hundred meters, and the space around them seemed to be smaller, the footsteps were less dull, and the interval between echoes became smaller.

Cao Xiaoseng, who was in the back, suddenly felt a chill in his neck and shouted, "Wait, it's above." ”

The three of them raised their heads almost at the same time and looked at the top of the underground laboratory, and they couldn't help but be stunned.

Ye Bai, who was just about to condense the power of the fire attribute, exhausted the power of the attribute in his hand and dissipated it, but fortunately he looked up and glanced at it, or he didn't know how to die.

"It's a corpse bat, turn off the analyzer on your glasses, don't emit a little light, and move quietly." Ye Bai looked up at this dense piece of corpse bats, they were still asleep, and he breathed a big sigh in his heart, if he didn't wake up these things, ten Ye Bai wouldn't be able to kill them all.

"How is that possible?"

The medicine spirit's face was full of incredulity, the corpse bats she knew, this was something that would only appear in the early days of the Dark Age, strictly speaking, the corpse bats were not living things, they were the things of the dead that were produced from a large number of corpses, they had no brains, no thoughts, and only knew how to suck fresh blood.

Whether it's a human or a mutant beast, as long as it touches the whole of the brain, when the mutant beast or human flies again, it will become a dry skeleton.

They resemble movable pieces of flesh, a bit like pre-Dark Age bats, and they were created from corpses that were later called corpses.

"Haven't these things been around for decades! How did it come back out now? There were no major wars, and where did they come from? ”

Yao Ling asked a series of questions, and she couldn't figure out how there could be so many corpse bats.

Cao Xiaoseng looked at the corpse bat above his head, and the corners of his mouth kept pulling out silk threads, and he instantly understood what the cool thing between his neck was.

"Maybe these corpse bats were not produced from a large number of corpses, and it is possible that someone specially cultivated them." Cao Xiaoseng suppressed the urge to break the corpse bat on his head into ten thousand pieces, and explained to the medicine spirit.

"That's right." Ye Bai pressed the shooting device on his glasses, slapped off a claw on the upper part of the corpse bat's wings, and transmitted it to the wisdom of Yao Ling and Cao Xiaoseng.

"Little paws! It's a lot like the paw prints on the wall when we first came down. The medicine spirit exclaimed.

"Let's get out of the way. This place can not stay any longer, as we all know, corpse bats are things that the six relatives do not recognize, no one can survive the attack of so many corpse bats, it seems that the owner of this place does not want to leave here alive at all. ”

The rear team changed to the front team, and the three of them did not dare to hesitate, and began to walk outside the basement led by Cao Xiaoseng.

As soon as he took a few steps, Cao Xiaoseng stopped.

"Maybe it's too late."

Yao Ling and Ye Bai also saw more than a dozen xenomorphs similar to black figures in front of them at this time.

"This is a water-shaped xenomorph that can change various positions of its body into weapons to attack each other, and it is like water in whatever shape it is, and it is very difficult to deal with." At the same time as the medicine spirit explained, Ye Bai also thought of the identity of the alien species in front of him.

"I didn't expect that we broke into an incredible place this time, and it is not a simple thing to be able to use more than a dozen water-shaped xenomorphs as a place to see the gate, you must know that the water-shaped xenomorphs are all entry-level."

Ye Bai took a look, since the back road was gone, they could only rush forward, it was impossible for the three of them to deal with so many water-shaped aliens, not to mention the corpse bat overhead.

"Let's go, keep going." Now there is really no choice but to go down.

I don't know why the water-shaped xenos just stood there and didn't move, as if to prevent them from going back, or if the owner liked to play with them in the palm of his hand.

Ye Bai felt helpless for the first time, helplessness who didn't know anything, since he entered this underground laboratory, the initiative had disappeared from his hands little by little, and now he had been forced to move forward.

The expression on Ye Bai's face did not change, he was still very calm, at this time, he couldn't mess with anyone, if he messed up, he wouldn't be able to get out of here at all.

The water-shaped xenomorph behind did not catch up, and with the departure of Ye Bai and the others, they disappeared again into the dark basement.

Ye Bai is now thinking about how to escape, but after thinking about it, there is only one exit when he comes in, and there is no way back now.

Suddenly, he felt his clothes being tugged, turned his head, and saw Yao Ling's eyes widen and he pointed to the front.

Ye Bai was a little confused, so he turned his head and saw the most unforgettable scene in this life.
