After descending to the B2 level, Gu Yanlin and his two companions were still searching for the entrance outside the elevator.

When they parted, Gu Yanzhi forgot to give Gu Yanlin the drug she used that could instantly wake up a person who was unconscious. Gu Yanlin wanted to wake up Experimenter No. 2 and force him to reveal the entrance and exit.

Unfortunately, perhaps because they went too far, Experimenter Number Two never regained consciousness.

Seeing that the elevator was running, the three cleverly hid in advance.

As soon as the elevator doors opened, before anyone could get out, Gu Yanlin darted inside, a dagger silently pressed against Gu Yanzhi's neck.

"Don't move!" Song Zhao was about to make a move to deal with this reckless person who had taken his wife hostage when Gu Yanlin spoke, and he stopped himself from moving.

"It's me, Yan Lin," Gu Yanzhi said.

"Sisters, it's you!"

Gu Yanlin lowered the hand holding the dagger and scratched his head awkwardly.

At this moment, Zhao Rui and Li Sheng also entered the elevator.

The three of them checked the external cameras and found that only the elevator area was a blind spot. Fearing being discovered by the cameras, they could only move around near the elevator and admitted with shame that they hadn't even explored the entire outer floor.

"Hurry up and change," Gu Yanzhi tossed the extra cleaning clothes in his hand to the three people, turned his back, and waited for them to change before turning back.

Under the guidance of Experimenter No. 1, the door was opened in yet another bizarre way.

"Good evening, Lab Technician Zhang."

Good evening, good evening.

"Laborer Zhang, have you heard? We have some excellent test subjects today."

"Really? I haven't heard about that. I'll go check on my experiment first, then we can talk properly later."

"Sure, sure, when you have time."

"I'm telling you, you'll absolutely regret missing out on this test subject."

"..."

Upon entering the B2 level, there is a stark contrast to the deserted and cold space outside.

The people on level B2 were all in a hurry, each carrying either test tubes or plates with unidentified liquids, rushing towards their destinations.

It's clear that Zhang, the lab technician, is quite popular. Even in such a tense and anxious atmosphere, some people would stop to greet him and chat about gossip.

As for Gu Yanzhi and the others who followed behind Zhang, they were ignored.

They assumed that Zhang, the lab technician, had just run into them and asked them to help clean the lab. This kind of thing had happened to other lab technicians before.

Although the cleaning staff comes to clean at a fixed time every night, they don't clean every laboratory. They are only allowed to enter and clean with the permission of the lab technicians.

More often than not, they are responsible for cleaning the outside corridors, restrooms, and lounges.

Just as Zhang, the lab technician, opened the door to his own lab and was about to go in, the door to the lab next door suddenly opened, and a man with a stubble beard and messy hair, who looked like he hadn't washed his hair in days, poked his head out and called out to Zhang.

"Brother Zhang, where's Xiao Li? Didn't Xiao Li come with you?"

"Oh, it's Xiao Liu. Xiao Li has been quite tired these past few days. I told him to go home and rest before coming back."

"Do you need to see him for something?"

"Hey! It's nothing serious. I haven't been up there for a few days, and I was missing some stuff, so I asked Xiao Li to bring it for me." Xiao Liu is the head of the lab next door. The experiment he's in charge of is at a critical stage, and he hasn't had a proper rest for several days.

"Oh, okay, I'll have Xiao Li bring it to you when he arrives."

"Okay, thank you in advance, Brother Zhang," Xiao Liu said gratefully.

"Are you cleaning the lab? I remember it was just cleaned a few days ago." After finishing the business, Xiao Liu looked at Gu Yanzhi and the others behind Zhang, the lab technician, with a puzzled expression.

The lab next door was only cleaned a few days ago; according to Zhang's habits, it shouldn't be time for the next cleaning yet.

"I heard we have new test subjects. I'm cleaning up properly in case one ends up with me," Zhang, the lab technician, said to Xiao Liu in a low voice after looking around to make sure no one else was there.

"A new test subject? The new test subject has excellent aptitude?" Xiao Liu asked in surprise, his voice unconsciously rising.

"Shh, keep your voice down," Zhang, the lab technician, gestured with his mouth, then said mysteriously, "His aptitude is exceptional. Who knows, if we assign a new test subject, my experiments might make a breakthrough."

"I'm only telling you this because we're good friends. Quite a few people know this, but there are definitely some like you who've been oblivious to what's going on lately and don't know. Don't spread rumors; the fewer people who know, the less competition there is."

There are only a few new test subjects.

The lab technician gave him a knowing look.

Xiao Liu understood immediately and gestured with his mouth as if he were zipping up a zipper, indicating that he would never tell anyone.

Xiao Liu lowered his voice, glanced at Gu Yanzhi and the others who were bundled up tightly, and thanked Zhang, the lab technician, saying, "Thank you for the reminder, Brother Zhang. Please have them come over here after they finish cleaning."

"No need to thank me, we're not that close. Alright, let's not waste any more time. I'll take them in first, and you can go to Inspector Liu's place later when you're done."

"I have important things to do next," Zhang, the lab technician, waved to Xiao Liu and led Gu Yanzhi and his group into his laboratory.

"Laborer Zhang, Brother Zhang," Lin Cheng said sarcastically to Laborer Zhang as soon as they entered the lab. After checking the lab separately and confirming that all the cameras were turned off, the members of Team 532 checked the situation.

Upon hearing this, they realized that this person hadn't been telling them the truth, claiming that he was just an assistant. Now it seemed that his position was much more than that.

"Hehehe, just lucky, just lucky. I arrived early. Actually, my skills are just so-so." Zhang, the lab technician, was almost soaked with sweat. He had already used up too many brain cells exchanging pleasantries with people outside. He didn't expect to face a hellish situation as soon as he came in.

The laboratory was quite large. Only Lin Cheng and Chu Guodong remained at the outermost edge to guard Zhang, the lab technician, while the rest of the people dispersed to various rooms to investigate.

Zhao Rui, who was inspecting the room inside, called out to Chu Guodong from inside the room.

"Is this the person we're looking for?" Chu Guodong followed Zhao Rui's voice and found the room filled with medical equipment. On the tables on either side of the bed were piles of colorful liquids and experimental equipment, and the scalpels were still stained with dried, dark red blood.

Lying on the hospital bed was a person whose skin was almost completely unrecognizable except for his face. His hair had been shaved off, and a large, clean hole was visible on the top of his head, revealing the internal structure at a glance.
