The team of seven is divided into three groups, two against the wall and one in the center, so that each direction can be taken care of.

An Yun's shirt was attached to the wall on the left, and the voice just now came from a room on the left.

The people behind walked backwards with their backs to them, guarding against possible danger behind them.

The group was well-trained.

They quickly moved near the source of the sound with their guns in hand.

Carson took the lead and gestured to the back, and a few people on the right against the wall quickly passed over and stuck to the other side of the door.

Now that they had surrounded the door, it was impossible for anything to slip out of front of their eyes.

The door in front of him was hidden, and Carson gently pushed it open with a gun, but the person did not enter immediately.

After the door opened for a long time, and there was no movement or anything to come out, Carson no longer hesitated, and took a few steps inside, the muzzle of the gun dangling.

The men behind him followed, their muzzles facing Carson's opposite, toward the rest.

The room is not big, it is full of all kinds of medicines, it should be a place like a medicine storage room, but it is very messy, the cart containing the medicine is horizontal at the door, the medicine is scattered all over the ground, and the pill bag can be seen everywhere.

The room was small, with no other doors, and after a brief and careful confirmation, everything was in order, not even a single mouse.

So where did the sound come from?

Unless they heard it wrong, but one heard it wrong, so many people heard it wrong?

Confirming that it was safe, several people in the room conducted a search.

An Yunshan reached out and picked up one, and she didn't recognize the words on it......

sighed lightly, and was about to throw it away, but was taken by Zhao Jianfeng on the side.

"It's an anti-inflammatory."

An Yunshan turned his head to look at him.

"Surprised?"

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

"Tranquilizer."

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

"It's ...... Muscle relaxants. ”

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

Most of the medicines here are similar to this, there is no fever and cold medicine like ordinary hospitals, and the only slightly normal ones are anti-inflammatory drugs.

Why should a hospital use these things, this is obviously not for ordinary patients.

Carson and the others are also aware of the problem here, what kind of experiment is this hospital doing?

Does it have anything to do with this disaster?

Why did the third group disappear here?

Instead of decreasing, the number of doubts has increased.

Later, Carson and the others searched for the back of the medicine cabinet and the roof of the floor tiles, and there were no hidden passages, no places like vents that might exist, and the sound rang and disappeared completely.

Nothing was found, and instead of breathing a sigh of relief, Carson and the others became more vigilant.

This shows that there is something else here besides them.

Of course, it could also be a small creature like a rat or cat, although they hadn't seen anything alive other than them for most of the day.

The people who were guarding outside didn't find anything, and after the group left the room, they could only continue to explore the bottom of the room.

"Bang dang!"

A group of seven people walked a few meters away, and the voice came again.

Click! Click! ……

The muzzle of the gun was turned, and it was pointed back again.

Everyone's faces were slightly condensed, and the voices were still coming from that room.

Why are you so sure, because at a distance of a few meters, there is only one room, and in the middle is a small hall similar to a waiting area, and it is clear that the small hall cannot hide anything at a glance.

And that voice has a small echo......

Carson narrowed his eyes, a little annoyed and angry by the sound over and over again, whatever it was, he had to find out!

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

It's the first time I've encountered something like this!

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

Even the medicine bag on the ground is in its original place.

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

So where does the sound come from?!

Once again, I entered the room and searched, but I found nothing!

Everyone looked at each other.

This time Carson didn't leave easily, he was going to stay here and wait until he got the sound to sound and catch one of them.

No one has an opinion, and if they can't find the source of the sound, they don't dare to walk freely.

They didn't enter the room either, but stood guard in the hallway of the door, scattered in small areas to make sure that all the movements around them could be heard.

The voice didn't seem to be regular, and this time the seven of them waited for half an hour, and the voice didn't appear again.

It's like knowing that someone is waiting for them at the door.

It feels weirder.

Just as Carson began to hesitate whether to wait any longer or leave for a while, the voice rang out again.

Whoa!

This time it was a different voice, like something was scattered.

But the things in the whole room were still in place, and there was no change, and the voice was indeed coming from the room!

Hell yes!

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

No one expected this situation.

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

Carson watched as the little female soldier walked past him without hindrance.

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

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

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

For the three noises just now, An Yunshan felt strange when he came in for the first time, the first time it was like something had been bumped, but in this room, there was nothing that turned over.

The last sound, as if something was scattered all over the ground, and in the room, even if the medicine bottle and bag were dropped, 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 voice rang out again.

Whew~Roar!

This voice suddenly filled the entire room, coupled with the short and urgent, as if something was howling, Jerica on the side of An Yunshirt was startled, squatted down reflexively, raised the gun high, and the muzzle of the gun was messed around, and he was a little flustered for a while.

As the saying goes, there is no harm without comparison, this voice is indeed infiltrating, and Jereke's reaction can be regarded as normal, but the little female soldier beside him has an indifferent face, and he didn't even raise his gun.

In such a comparison, it seems that Jerrick is a bit inferior.

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