The team of seven people is divided into three groups, two groups are attached to the wall and one group is centered, so that every direction can be taken care of.

An Yunshan was pressed against the wall on the left, and the sound just now came from a room on the left.

The people behind him walked backwards to them, guarding against possible dangers behind him.

The group is well-trained.

They quickly moved near the source of the sound with guns.

Carson took the lead and gestured to the back. Several people on the right side of the wall quickly came over and stuck to the other side of the door.

Now that they had surrounded the door, nothing could slip away from their eyes.

The door in front of him was a false impression. Carson gently pushed open the door with a gun, but the person did not go in immediately.

After the door opened for a while, there was no movement inside, and nothing was about to come out. Carson no longer hesitated and took a few steps in, shaking his gun around.

The people behind him followed, their guns opposite to Carson, heading towards the rest.

The room was not big, and it was filled with various medicines. It should be a place like a drug storage room, but it was very messy. The cart for the medicine was horizontally at the door, and the medicines were scattered all over the floor, and pill bags were everywhere.

The room was not big, there were no other doors. After a brief and careful confirmation, everything was normal here, and there was not even a mouse.

So where did the sound just now come from?

Unless they heard it wrong, but one of them was wrong, so many people were wrong?

After confirming safety, several people in the room conducted a search.

An Yunshan reached out to pick up one, but she didn't recognize the words on it...

He sighed lightly and was about to throw it away when Zhao Jianfeng, who was beside him, took it over.

“This is an anti-inflammatory.”

An Yunshan turned his head and looked at him.

“It’s a surprise?”

An Yunshan shook his head, then took another medicine bag from the cart and handed it to him for identification.

"Sedatizing agent."

An Yunshan took another bottle from the broken frozen medicine cabinet.

“This is…muscle relaxant.”

When Zhao Jianfeng saw this, he no longer waited for An Yunshan to hand it to him, but searched for it himself.

Most of the medicines here are similar, and they do not have the fever and cold medicines like ordinary hospitals. The only slightly normal one is anti-inflammatory drugs.

Why do a hospital use these things? This is obviously not for ordinary patients.

Carson and others also realized the problem here. Is this hospital doing some experiments?

Does it have anything to do with this disaster?

Why did the third group disappear here?

Not only did the doubts not decrease, but they increased a lot.

Later, Carson and others, together with the back of the medical cabinet and the floor tiles, searched one side, without any secret passages, and there was no possible place like a vent. The sound rang out and disappeared completely.

Not finding anything, Carson and others not only failed to breathe a sigh of relief, but instead became more vigilant.

This shows that there are other things here besides them.

Of course, it may also be small animals such as mice and cats, although they have not seen any living creatures other than them for most of the day.

The people guarding outside did not notice anything. After leaving the room, the group could only continue to explore.

"Clang!"

A group of seven people walked out several meters away, and the sound came again.

Crack! Crack!…

The muzzle turned around and looked back again.

Everyone's faces were slightly calm, and their voices were still coming from that room.

Why is it so sure? Because at a distance of several meters, there is only one room, and in the middle is a small hall similar to a waiting area. It is obvious that there is nothing hidden in the small hall.

And that sound has a slight echo...

Carson narrowed his eyes, and was a little annoyed and angry by the sound again and again. No matter what it was, he would find it!

The seven people returned again, and the atmosphere was a little condensed, and even An Yunshan frowned.

This is the first time I have encountered such a thing!

When I came to the door again, the door was still open, and everything inside was still the same as they were when they left.

Even the medicine bags on the ground are in their original location.

An Yunshan glanced at him and knew that there was no one or anything here at all!

So where does the sound come from?!

Once again, I went into the room to search and could meet, but I didn’t find anything!

Everyone looked at each other.

This time Carson did not leave easily. He planned to wait here, waiting for the sound to catch a current situation.

No one has any objection, and if they cannot find the source of the sound, they dare not walk at will.

They didn't even enter the room, they just guarded the corridor at the door, scattered in a small area to ensure that all the movements and stills around could be heard.

The sound seemed to be irregular. This time, the seven people waited for half an hour, and the sound did not appear again.

This feeling is like knowing that someone is waiting for them at the door.

It feels even more strange.

Just as Carson began to hesitate to continue waiting or leave temporarily, the voice rang out again.

Hurry!

This time I changed my voice, as if something was scattered.

But the things in the whole room were still placed in place without any change, and the sound was indeed coming from the room!

What a hell!

Several people were holding guns, nervous and a little confused.

No one expected this situation.

An Yunshan's eyes flashed slightly, and he walked towards the room with a gun.

Carson watched the little soldier walk past without stopping him.

An Yunshan stood in the middle of the room, and Jerek followed him in and stood beside her.

"Don't be afraid, I'm here." Jerek smiled at An Yunshan.

An Yunshan turned her head and she was really not interested in people who were all yellow in turtles.

An Yunshan felt strange when he first came in with the three noises. The first time he was like something was hit, but there was nothing in this room.

The last sound was like something scattered all over the floor, and even if the medicine bottle and medicine bag fell in the room, it would not be that kind of sound.

so……

An Yunshan didn't move, and she had a little guess in her heart.

Soon, the sound rang again.

Huh~roar!

The sound suddenly filled the room, and it was short and fast, as if something was howling. Jerica next to An Yunshan was startled, and squatted down like a conditioned reflex, held the gun high, and the muzzle was scattered everywhere, and she was a little panicked for a moment.

As the saying goes, there is no harm without comparison. This voice is indeed cunning. Jerek's reaction can be considered normal, but the little female soldier next to him looked calm and didn't even raise a gun.

This comparison makes Jerek look a little inferior.

But, what is this sound? Where did it come from?
