Yan Shi obeyed her unconditionally and nodded obediently.

The ground was covered with dead bats. When I squatted down and looked carefully, the system kept screaming and the roaring eardrums rumbled.

When I was bored, I was annoyed. Today's system was particularly surprised and threatened: "if you scream again, I'll plug the bat into you."

System: "CBI, didn't you agree to be each other's angels? Why do you do this to me? "

Shi Li: "then you treat me as a devil."

At the end of the hall, there is a closed bronze door.

Shi Li walked to the door and saw a huge lock with thick wrists hanging on the bronze door. The relief on the door was a terrible devil's head, and a sign of "no entry" was erected next to it.

"Open it."

Time away from the command line.

Yanshi stepped forward and unscrewed the giant lock without effort.

For level zombies, such a lock is no different from paper paste.

"Squeak"

The heavy bronze door opened slowly to both sides, and a fishy wind blew from inside.

Inside the door is a spiral staircase, winding down to the ground. It's dark inside. You can't see what's below.

Shi Li raised his head and walked to the stairs without squinting.

I'm afraid this is the entrance to the underground laboratory.

System: "people are so afraid, master. Let's go back. I don't want to go to that place."

Shi Li: "hehe, you know I'm the master. You have to keep up with me wherever I go."

System: "no, I'm still a fairy. Don't you have a heart of pity?"

Shi Li: "do bats eat? Enough to shut your mouth. "

System: "master, let's go down. I can't wait."

Down the winding ladder, the induction lights on both sides turn on in turn, and the dim yellow light shines on the circular ladder.

The stairs are full of dust, and there are many spider webs on the wall. It seems that no one has been here for a long time.

Inexplicably, there is a feeling of horror game.

Shi Li doesn't know how long he went down. In short, he is farther and farther away from the ground, but the more he goes down, the more light comes up from below.

Yan Shi walked side by side with her and said vigilantly, "be careful, there may be someone below."

"There should be no one." Shi Li shook his head: "even if there is, I'm afraid it's not human."

When I opened the door just now, the iron lock was full of rust, indicating that no one had been here for a long time.

Let alone the lack of air circulation, even if there are refugees below, they should have starved to death.

They finally came to the end of the stairs. Below was an empty white room, but there was still electricity.

The two automatic doors seemed to sense that there were guests and slowly slid open to both sides.

Suddenly, a bright light came out of the door.

Shi Li blocked his face with his hand until his eyes adapted to the light and looked ahead.

In front of her was a huge white laboratory.

The laboratory was empty, with tables and chairs toppling and in a mess.

On the white desk, there were spread out notes, pieces of paper and materials were thrown on the ground, and the chair fell aside.

All this looks like the experimenter left in a hurry and hasn't had time to clean up.

Shi Li went to his desk and touched it.

The table is covered with thick ash. No one has been here for a long time.

When she saw an experiment note on the table, she picked it up, dusted it and opened it gently.

Just then, Shi Li suddenly heard a loud noise behind him.

Like the sound of broken glass.

She immediately turned around and put on a defensive posture.

But there was no crisis behind him. Yanshi stood by a door and looked straight inside.

On the ground beside his feet, a glass fell to the ground and broke. It should have been knocked over by him just now.

"Yanshi, what are you looking at?" Shi Li walked over in surprise.

Yan Shi looked blankly at the front and didn't answer her for the first time.

Along Yan Shi's line of sight, Shi Li looked up and suddenly became stiff.
