"We stayed here for a period of time without any problems, so it should be fine. You guys rest up, I'll be on guard." Shangguan Yun said to Xiao Chen and Qin Xiaoyue.

Xiao Chen and Qin Xiaoyue were already very tired, and they did not have to be polite. They directly leaned into a corner and rested.

The girl beside Shangguan Yun asked curiously, "Big Brother Yun, why are they standing?" Isn't it more comfortable to sit? The group of people behind them were sitting and resting.

Shangguan Yun looked at the girl as if she were looking at a noob, "The room is so small, if you sit down there, there's no way a zombie will be able to respond."

Shangguan Yun's words caused the people sitting in the back to all stand up. They all began to lean against the wall to rest.

In the following time, the entire room fell into silence. After Xiao Chen and Qin Xiaoyue rested for two hours, the exhaustion in their bodies disappeared.

The two of them heaved a sigh of relief. Although this place could feel a stifling pressure, now that they had recovered their strength, there was no need to fear this kind of pressure.

Qin Xiaoyue looked at the time. It was three in the morning. Xiao Chen asked, "Shangguan Yun, when did they agree to move out?"

"Five in the morning." Shangguan Yun raised his eyebrows and said, "There are a lot of people here this time, but this underground laboratory is a little too big."

Qin Xiaoyue exchanged a glance with Xiao Chen. They only saw three tunnels. It seemed like they only saw a small part of it. What about the researchers who used to work here? "

"They all escaped. I heard that when the Greyhound escaped, more than half of the researchers here were injured, and the rest of them didn't dare to show their faces again after they escaped. One of them just happened to fall to our base and was recognized by the military, which is why the truth was revealed. This lab is so scary, if the Greyhound escaped, we normal people would not be able to survive, which is why the higher-ups decided to solve all the hidden dangers here." Shangguan Yun explained.

"So that's how it is." Qin Xiaoyue exchanged a glance with Xiao Chen. To be resting in this laboratory, who was the one who made such a bold decision? This was the Gray Man's production base.

Xiao Chen and Qin Xiaoyue had decided to make their move now. To them, the longer they stayed in this place, the more dangerous it would be.

"Shangguan Yun, we're going out now, what about you?" Qin Xiaoyue looked at Shangguan Yun.

"Count me in." Shangguan Yun also felt that it would be dangerous if they stayed any longer.

When he followed Qin Xiaoyue out the door, the six or seven people behind him also hurried to catch up.

Qin Xiaoyue had already noticed that these people were clearly Adepts. Although their levels weren't as high as theirs, they were at least considered experts.

Once they left, the rest of the people in the room couldn't help but ask, "What should we do?"

"You stay here." Shangguan Yun raised his eyebrows as he spoke. The remaining people, including the girl, were all the students they had rescued from the school. They couldn't possibly be of any help when they came to the laboratory.

After the group left the room, they decided to push everything in one room at a time. As long as there was a grey-skinned person inside, they would behead them all.

The group directly opened the room next to theirs. This room was three times the size of the one they had stayed in before. There were over ten large vats inside, and each vat contained a person. Two of these people's skin had already turned gray, while the rest were completely pale.

"AHH!" A scream came from behind them. Shangguan Yun glared viciously at the woman who had followed them out and said, "Scram!"

The girl covered her mouth and whispered, "I know two of them. They were both students who went missing in school."

That also explained why she was screaming, because there were people she knew.

"How long have they been missing?" Qin Xiaoyue asked.
