Watch out One of you is a ghost.

In the dim elevator space, the sounds of two people's breathing were clearly audible.

However, there were clearly three people standing here.

No matter whether it was No.1 or No.2, they could only hear each other's breathing.

This specially made elevator space was quite large, so when the three of them entered, they stood back to back in a defensive formation.

Now No.1 looked around a little and did not see the figure of No.4.

He said in a low voice, "No.4, you left the formation."

As soon as he finished speaking, No.1 felt someone gently lean against his back, and his breathing calmed down a little.

Soon, the elevator stopped descending and the elevator doors opened.

A rush of icy air poured in. In the pitch black darkness that was invisible when you stretched out your hand, a gloomy passage appeared in front of the three people.

But none of them moved. No.1 said in a low voice, "Go back, No.3 is still upstairs."

Although No.3 had reacted a bit strangely earlier, from the perspective of the three people, they did not find that No.3 had already been attacked.

No.2 went forward and groped on the inner wall of the elevator compartment, and finally touched the elevator button.

However, no matter how No.2 operated it, the elevator did not move at all.

During this time, No.1 shouted into the walkie-talkie a few times in a low voice, without any echo.

If you listened carefully, you could hear a faint electric current.

Time passed bit by bit, and the three of them fell into silence.

Soon, No.2's voice rang out, "It looks like we can only move forward..."

No.1 shook his head and said, "Moving forward is likely to be dangerous."

"This elevator didn't come down from the ground for too long, proving it's not far from the ground. But in the time we've been down here, there hasn't been any movement from No.3 upstairs."

"I suspect the enemy has already discovered us, and No.3 is most likely already dead."

After No.1 finished speaking, the elevator compartment fell silent again for a short while.

Drip -

Suddenly, No.1 heard the sound of some kind of liquid dripping onto the floor.

In an extremely quiet environment, such a sound was exceptionally jarring!

"What sound?!"

There was some panic in No.1's voice.

At this moment, he realized that the shoulder-to-shoulder, back-to-back defensive formation that the three of them had maintained was messed up when No.2 went to touch the elevator buttons!

He sniffed hard, and immediately a sense of panic spread in No.1's mind!

It was the smell of blood!!

When No.1 spoke again, his voice already contained some tremors caused by fear, "Get close! Get close! Defend!"

In an instant, No.1 felt a sense of security as the body behind him leaned against him.

In the darkness of the elevator compartment, No.2's voice rang out from behind No.1: "No.4, come over!"

At this moment, No.1's whole body shuddered violently, and his body turned cold in an instant.

Because from his perspective, he could faintly see No.2 who had just gone to touch the elevator buttons.

No.2 was still standing there motionless.

The "drip" sound just now also came from that side, as well as the faint smell of blood.

No.1 could be certain that the person behind him who was obviously imitating No.2's tone was definitely not No.2.

It was either No.4, or... someone else.

If it really was No.4, he wouldn't play this kind of impersonating a teammate joke at a time like this.

It seemed that he had sensed something from No.1's body shudder just now. The "No.4" who had been leaning against No.1's back turned around and put his hand on No.1's shoulder.

No.1 worked up his spirit and pretended he hadn't guessed anything. "Now we move forward, we can't sit here waiting to die!"

No.2's voice immediately rang out from behind No.1: "Yes!"

No.1's thinking was simple. Take advantage of the fact that the person impersonating "No.2" behind him had not yet realized that he had already discovered he was an imposter, and delay as much time as possible.

If he could delay until the second team discovered this place, he would still have a chance to live!

In the gloomy underground passage, No.1 only felt that the hand resting on his shoulder was like a demon claw from hell.

The two of them slowly moved forward in this dark and quiet underground passage.

Not even half a minute after leaving the elevator compartment, the entire passage was full of cool breezes, but even so, No.1's whole body was already soaked in sweat.

Ka, ka -

Suddenly, bursts of faint electric current sounds came from the walkie-talkie on No.1's collar, and the voice of No.1 of the second group came through: "Team one, how many of you are there now?"

In one second, several answers went through No.1's mind.

Finally, he chose to answer: "Four."

Immediately after, the urgent voice of No.1 of the second group came from the walkie-talkie: "Be careful! There is a ghost among you!!"

In the dead silence of the underground passage, this sentence from No.1 of the second group was exceptionally jarring.

......

Outside the Lu Yuan Clinic building, a few minutes ago.

The four members of Team Two were standing guard around the corpse of No.4 of Team One.

Why did Team One suffer an attack without sending out any notification?

This was the question No.1 of Team Two was thinking about.

At this time, bursts of crackling electric current sounds came from the walkie-talkie, and the voice of No.1 of Team One came through: "A secret passage has been found in the warehouse behind the main building, it's an elevator. Team One is entering."

No.1 of Team Two turned his head to look towards the rear of the main building. There was indeed a large square back there, which his team had just passed through earlier.

Behind the square were overgrown weeds, and faint sounds of water ripples could be heard from behind those weeds.

Looking at the corpse of No.4 of Team One in front of him, No.1 of Team Two cautiously asked into the walkie-talkie: "Team One, how many of you are there now?"

The voice of No.1 of Team One quickly came from the walkie-talkie: "Four."

Abruptly, No.1 of Team Two immediately said, "Be careful! There is a ghost among you!!"

The "ghost" that No.1 of Team Two referred to here was naturally not something like a wandering spirit or jiangshi, it was jargon among mercenaries that referred to moles, spies and the like.

Next, No.1 of Team Two waved his hand at the three people behind him, and immediately ordered: "Go support them immediately——"

Halfway through, No.1 of Team Two corrected himself: "No! Retreat immediately! Call the two psychic commanders to provide support!"

The other three soldiers immediately nodded, and the four formed a defensive formation as they carefully retreated.

Swish -

The night wind blew through the weeds in the abandoned medical academy, making faint rustling sounds.

Under the veil of night, it seemed like something was bending large swaths of grass.

Whoosh!!

Suddenly, three of the four people in Team Two only felt a gust of wind blow past them. When the three of them turned to look, there were only three people left in the four-man team.

"Where's No.2?!"

No.1 of Team Two asked in horror. No.3, who was closest to No.2, said in panic, "I didn't see... Didn't see anything..."

Crackle, crackle!!

Abruptly, the faint sound of some creature's teeth chewing flesh and bone slowly emanated from the clump of weeds next to the three of them.
