Now that the light is on, it proves that there are definitely people in the room. Could it really be Lin Yaru inside?

"Alright, I have brought you here. There are two rooms, and the target person should be inside. I can't go any further now. From this angle, I can keep an eye on the best position, so I'll stay here to guard for you."

"Okay, I understand. You also be careful."

"Remember, you must act quickly."

Anying still made a special reminder, and then nodded, before getting up and walking towards the inside.

After arriving outside the door, Ye Chen only quietly stopped, and then carefully listened against it. He seemed to vaguely hear the sound of two men talking inside.

However, he was not sure whether the soundproofing of the place was particularly good or if the two people were deliberately lowering their voices. In any case, he couldn't hear it very clearly.

He could just make out that there seemed to be people talking inside.

It was already this time, so even if there were people, they should have already been in dreamland by now. Yet unexpectedly, they were still chatting here.

Looking through the window, he glanced at the entire area. Then, behind this spot, he realized that the rest was all stone walls, without any windows at all.

That is to say, it was an impossible task for Ye Chen to try to enter through the windows.

Thinking of this, he just nodded his head, then tidied up his clothes, and walked to the door, knocking lightly on it.

At this time, the two guards inside were planning tomorrow's activities. Suddenly hearing the knocking sound from outside, the two men immediately looked at each other with caution.

This place was extremely vigilant, and under normal circumstances, it was impossible for anyone to easily come here.

Could it be the zoo staff? But they remembered that they had heard before that there should be no staff here, especially at this time.

"Who is it?"

Although the man doubted this situation, he was still very cautious. He did not directly go to open the door but shouted from inside.

"Oh, I just wanted to ask why there are people here? I'm here for the night patrol tonight, as I recall, there weren't people here before. Who are you? Are you zoo staff?"

"Oh, yes, we're staff, we're just fixing something here temporarily, so we're making do here for the night, we'll be leaving tomorrow."

"Making do for the night? Really? How can you just make so simply for one night? Moreover, I haven't heard any orders from above. How about this, you open the door and let me take a look. After confirming you are our people, then I'll be at ease."

At this, the man was momentarily stunned.

They were only here for a temporary hideout and never thought to disturb others.

If they didn't open the door at this moment, it would surely arouse suspicion from those outside. So, it seemed he had no choice but to deal with the situation temporarily.

After exchanging glances, the two men put a tool they were holding behind their waists.

Just in case something happened, they would definitely take measures against him and absolutely would not let him easily leak this information.

Finally, the man walked to the door, gently opened it, and then looked outside. At this time, Ye Chen was standing right in front of him.

"Are you in charge of inspecting the zoo? How come I didn't know about this? Moreover, no one told us before we started working that there would be people coming at this time. We're just staying here overnight."

"Oh, how many of you are there?"

As Ye Chen spoke, he prepared to poke his head in for a look, but he found that the man was very vigilant, standing at the crack of the door and not giving him any chance to enter.

"Oh, just the two of us?"

"Two people, then can your companion come out for me to see?"

"Is that necessary? I've already opened the door and told you that we're just temporarily staying for the night and will leave early tomorrow. Let's not complicate things further."

"Sigh, comrade, if you say that, you're in the wrong. I'm responsible for the inspection here. Why can't you let me in to check?"

While talking, Ye Chen suddenly reached out and pushed the door open.

Then, he took out a can of aerosol spray from his pocket and vigorously sprayed it in the faces of the two men.

Very quickly, the two men didn't even have time to react before they went limp and collapsed to the ground.

Ye Chen pocketed the aerosol spray again and then put his hand on their necks to check—fortunately, their breathing was steady; they were merely temporarily unconscious.

However, Ye Chen knew that the effect of the drug was very short-lived, lasting at most half an hour. After half an hour, they would wake up again, and regarding the events that had just occurred, they would have no memory of it at all.

He entered the room and then took a glance inside. There were two doors in total, one on the east side and another on the west side.

The door on the west side was tightly closed, while the one here was padlocked with an iron lock. It seemed like it was securing something.

He went to the door and tried to pull the lock, but it was tightly fastened.

At this time, Lin Yaru inside the room was not asleep at all. She had been listening to the noises outside.

Just now, the two men were talking to someone, and she was wondering if she shouted out at this moment, would someone rescue her?

But she felt that maybe she was being too simplistic in her thinking and didn't want to bring unnecessary trouble upon herself at this time, so she kept quiet.

"Who's there?"

When she heard someone tampering with the door lock, Lin Yaru suddenly became alert, because she felt that this person was probably not one of her guards.
