Yun Xin cautiously pushed the door open to a crack and quietly inquired about the situation outside.

Outside the door, it was also brightly lit, and there was no one at a glance.

She opened the door, and found that outside the door, there was a long corridor with doors on both sides of the corridor, leading to a different room.

She took the glass, chose a direction, and walked quickly towards the end of the hallway.

At the end, there is the elevator.

Yun Xin excitedly pressed the elevator door button.

However, the elevator door was not opened as Yun Xin wished, and a cold female voice sounded in the empty corridor.

"Ding~ Please put the work card into the card slot, scan it, and then start the elevator."

As soon as this voice sounded, Yun Xin looked around in fright.

It's just that the sound is so loud that no one shows up.

Although Yun Xin had doubts in his heart, he was not timid, but he was more cautious.

Only then did she notice that there was a card-sized card slot on the elevator switch button, which meant that the elevator needed an identification card to take it.

Unable to get out for the time being, Yun Xin had to go back the way he came, and began to look for cards, looking for useful things by the way.

Yun Xin walked along the wall, and every time she came to the door of a room, she gently pushed the door open, and when she saw that there was no reaction in the room, she entered the room.

Every room here is much the same, there are laboratories, there are laboratories, there are virus rooms......

It's just room after room, Yun Xin didn't find a single living person, and those who could be here seemed to be dead.

Where have all the people here gone?

At the other end of the corridor, there is no elevator, there is only one large room here, double doors, but it is locked with iron locks and chains.

Although the double door was locked, it was forcibly pushed through a gap, and Yun Xin wanted to see the situation inside.

Her eyes slowly crept into the gap and looked inside.

Suddenly, a pair of blood-red eyes suddenly appeared in the gap.

Yun Xin was so frightened that she couldn't keep her feet, her steps were unsteady, and she fell to the ground, her little heart "fluttering" and beating.

She saw a big, big eye, which was blood-red and not like a human eye.

What kind of monster is inside?

Why is such a monster here?

The monster inside seemed to have spotted Yun Xin as well, and he suddenly pounded the door frantically.

This monster's strength is not small, and every punch he throws can knock the double door uneven.

Following this trend, the door was quickly smashed down by the monsters inside.

Now he can't enter the space, and without knowing the enemy, Yun Xin doesn't dare to confront him.

She crawled to her feet, and she saw that those blood-red eyes were still staring at her, and her heart beat half a beat in fright.

Without hesitation, she turned around and ran towards the room where she had woken up.

The faster Yun Xin escaped, the more irritable the monsters in the house became, and the faster they pounded the door.

Just as Yun Xin ran to the door of the room, she saw the double doors of the room at the end of the room fall in response.

She didn't have time to look closely, so she ran straight into the room, locked the door, and blocked the door with a cabinet table.

When she was ready, she pricked up her ears to eavesdrop on the situation outside the room.

The hallway was silent, as if everything that had just happened was an illusion.

The more silent it was, the more uneasy Yun Xin became.

It stands to reason that the monster should have escaped from the locked room, and since he saw Yun Xin, he should chase after him, why didn't there be any movement in the corridor.

Just when Yun Xin was nervous, suddenly, there was a strong banging on the door outside the door.

"Knock~Knock~Knock~"

One after another, Yun Xin was so frightened that he held his breath.

According to the speed at which the monster continued to fight, Yun Xin felt that this gate would not be able to resist for long at all.

With the help of spiritual power, Yun Xin blocked the door to prevent the monsters outside from succeeding.

But I was already incoherent in my heart.

Damn, it's really coming!

Hercules? Doesn't it hurt to pound the door like this?

Yun Xin looked at it and saw if it hurt for him.

"Click~", suddenly, a fist smashed through the door, and the fist couldn't be contained and stretched out directly.

The difference was 0.00001 mm, and the fist almost hit Yun Xin's head.

The fist that can break the door, if it really hits Yun Xin's head, then she is not a head burst.

For the sake of his life, Yun Xin directly blessed with spiritual power, covering the whole body.

The fist stretched out the door, and then, instead of thrashing again, the monster leaned its head into the doorway and went inside to see if Yun Xin was inside.

Yun Xin was also fast, squatting directly on the ground, hiding under the table, and due to the blind spot, the monsters outside did not see Yun Xin.

The monster left abruptly, and then there was silence again.

After waiting for more than ten minutes, seeing that there was no movement outside, Yun Xin thought that the monster was leaving, so he crawled out from under the table, and then looked out through the broken doorway.

This look scared Yun Xin's soul away.

Because, when she looked outside the doorway, the monster outside the doorway was also looking inside the house with a blood-red eye.
