"Wait a minute, aren't they being a little too docile? The one that passed by us just now also reacted to us," Yang Ji said strangely. "They seem to be asleep; they didn't even move."

Upon hearing Yang Ji's words, a sentence he had seen in the experimental report flashed through Yin Chengjue's mind—once a person is infected with the virus, they will purposefully seek out normal people, scratching and biting them until they confirm that the other person is infected with the virus, then they will leave to find the next target.

At that time, it was still in the early stages of experimentation, and everyone called this source a virus. Later, after Dr. Fu's in-depth research, he beautified this source of infection as a "genetically modified source".

The experimental report didn't say what the person injected with this "genetically modified source" would become, nor did it say whether they would retain the habits of the previous mutants. But thinking in this direction, it seems that the reason why these mutants ignored Liu Qingling can be explained.

To verify his guess, Yin Chengjue also groped his way toward the room, but before he could even touch the door, someone grabbed his hand.

Rong Yu's deliberately lowered voice came: "Where are you going?"

Yin Chengjue: "I'll go in and take a look too."

Rong Yu: "Then I'll go too."

But just as Yin Chengjue reached the door, he heard a strange roar coming from inside.

The sound startled everyone else as well.

"Has the mutant started to go berserk? Why? Did Old Liu run into something?" Yang Ji tensed up instantly.

Yin Chengjue took another step forward, and as soon as his hand touched the door, strange roars echoed from inside the room!

These sounds meant nothing to Yin Chengjue, but the people watching the monitor around the computer light source were startled. They moved, and the clothes that were blocking the light slipped down, instantly revealing the computer light source!

"Roar! Roar! Roar!" Now that's it! The four mutants immediately seemed to have been injected with chicken blood and came back to life. They rushed out of the door and pounced straight at Yin Chengjue, who was closest to the door!

The computer light stimulated the mutants, and also allowed Yin Chengjue to see their movements clearly. Seeing them rushing towards him, he immediately pulled Rong Yu aside and grabbed a chair to block them.

The mutant NPC, whose view was partially obscured by the chair, looked up and met Yin Chengjue's cold gaze, which shone through the dim light. Seeing his aloof demeanor, he had no choice but to temporarily ignore the "tick Yin Chengjue" voice coming from his earpiece and turn to run after Wei Shu and Lei Miao.

And so, in this room with only a computer screen as a light source, this amazing scene appeared.

Wei Shu and Lei Miao ran around the room laughing and joking, with two strangely dressed people chasing after them. The whole space was filled with Wei Shu's smug voice saying, "Come on~ Come on, catch me~ I can't catch you~"

The two oddly dressed people got tired of running and went to catch Qin Ke and Xiao Xiao, so the scene from the previous paragraph was copied and pasted.

Even Yang Ji, who was initially screaming in terror, was now numb.

Liu Qingling: "..." You guys have ruined the whole scary atmosphere.

Yang Ji couldn't help but complain: "After what you guys did, I feel like I don't have to be afraid of haunted houses anymore."

Two other oddly dressed people had already been led outside by Hua Yun and locked out.

Once the atmosphere of terror was broken, everything became simple.

Open the room doors, drive the mutants out into the hallway, close the doors, and completely empty the three rooms to facilitate a thorough search.

The haul this time was clearly substantial. The middle room of Yin Chengjue's house used to be Dr. Fu's wife's bedroom. There were framed photos of Dr. Fu and his wife on the table, and a lot of information proving the identity of the bedroom's occupant was inside the cabinet.

The reason I say "in the past" is because Dr. Fu's wife has been dead for ten years.

The detectives came here at nightfall because they received a letter of commission from Dr. Fu, who asked them to find the murderer who killed his wife ten years ago.

Ten years have passed and the murderer has still not been caught, so Dr. Fu's letter did not express much hope. He simply asked the detectives to come back and investigate, and he also paid a deposit in advance.

But who could have imagined that after arriving here, I would encounter these things?

I thought that finding the murderer was a lie to lure people here, but I never expected that Dr. Fu's wife really did die ten years ago.

The room looked clean and tidy, obviously someone had come here regularly to clean and tidy it up, and apart from Dr. Fu, it was unlikely that anyone else would come here to clean it.

"But if this is a room that Dr. Fu cleans regularly, why are there still mutants here? Shouldn't it be properly protected?" Wei Shu asked, somewhat puzzled.

"Yes, since Dr. Fu wants to find out the real culprit and is so protective of his deceased wife's room, he must cherish it very much. Logically, he shouldn't let anyone else in, unless..."

"His wife is one of those four mutants!" Everyone quickly realized the same thing!

"By the way, has anyone seen what those four mutants look like?" Wei Shu looked around and found that everyone's expression was stiff.

“So…” Yin Chengjue slowly began, “The reason those two mutants kept chasing us and hovering in front of us was because they wanted us to see their faces clearly?”

"That's not right. None of us know Dr. Fu and his wife. Even if they were standing right in front of us, we wouldn't recognize them!" Qin Ke said, somewhat puzzled.

But after this question was voiced, everyone suddenly realized something and looked at the three people who had returned to the group later.

"Have you met Dr. Fu?" Liu Qingling squinted at Yang Ji.

Yang Ji waved his hands repeatedly: "I didn't!"

Yin Chengjue: "Only undercover agents and murderers can lie. If you are not an undercover agent in a certain mission line, then you are the murderer that the detective line is looking for."

Yang Ji looked innocent: "I really didn't! Old Liu, you know I can never hide anything on my face!"

Liu Qingling: "...Don't you feel guilty saying that? Do you think everyone doesn't watch the show? Everyone already knows that you were an undercover agent in the variety show 'Triumph in the Skies' and fooled everyone all by yourself, okay?"

Yang Ji: "That's an exaggeration!"

Wei Shu grinned and said, "Yes, yes, my mom loves watching your variety show the most. She always says you're her idol!"

Yang Ji's face lit up with delight: "Oh my, this is truly my honor!"

Wei Shu: "So, Teacher Yang, you don't need to be so modest. Being an undercover agent is really your forte. You'll definitely succeed this time! Go for it!"

Yang Ji waved his hand and laughed, "Oh, you flatter me, you flatter me. Look at this child, he really knows how to talk... cough cough cough! But those last two sentences are not right, I really am not an undercover agent this time!"

Rong Yu and Hua Yun: "..." They don't know if you're lying, but we do! Since you can lie and haven't been warned on the radio, it means you're either the undercover agent or the murderer. Now that you've denied one of them, it's like the murderer has revealed their identity!

Rong Yu sighed in regret, wishing she hadn't been on the detective team this time, otherwise she would have won by now!

Hua Yun also felt sorry for Rong Yu, because Hua Yun, like Rong Yu, was on the escape route this time.

Like them, Liu Qingling was also on the escape route.

However, among these three known members of the escape line, there is an undercover agent.

Hua Yun, the leader of the escape line team, glanced at Rong Yu and Liu Qingling without leaving a trace. After observing them for so long, he still couldn't determine who the mole among them was.

Rong Yu? That's quite a possibility.

Yin Chengjue was also observing the micro-expressions of the three of them. In his opinion, Yang Ji, Rong Yu, and Hua Yun must have met Dr. Fu, because when he asked this question before, Hua Yun and Rong Yu did not answer him directly, only Yang Ji did.

Therefore, in his view, Yang Ji was someone who could lie. In addition, Yang Ji himself denied the possibility of being an undercover agent. So, Yang Ji was the murderer.

Yin Chengjue stroked his chin, somewhat unsure how much of Yang Ji's words were true.

"Let's go over this storyline again," Liu Qingling suggested. "Anyway, we need to know the plot, no matter which main storyline it is."

“Sure, it’s not bad to hear this story anyway,” Hua Yun agreed.

Liu Qingling: "Let me start with myself. Ten years ago, an accident happened in this laboratory, which caused most of the members in the laboratory to mutate. Everyone knows this, right?"

The others nodded.

Liu Qingling: "Then, judging from the clues in this room, Dr. Fu's wife died before this accident. The cause of death was murder. There were three murderers. Two of them have been caught by Dr. Fu, and one escaped. So Dr. Fu has been looking for him for ten years. Is that okay?"

Liu Qingling: "Dr. Fu discovered that the result of this accident was of research value, so he was willing to go against his superiors' wishes and secretly conduct research. He continued his research until recently, when he finally cultivated three highly active ultimate modified gene sources. So he sent invitations to the Dark Treasure Hunting Team and the Dark Detective Agency, inviting them to search for the 'Water of Life' and the murderer who killed his wife, respectively."

Liu Qingling: "So, the Treasure Hunting Team and the Detectives arrived at night, along with three people who had broken in without permission. They were people Dr. Fu did not expect."

"In other words, the person Dr. Fu is looking for is definitely not among the three people on the escape line?" Rong Yu followed this line of thought and came to this conclusion.

“That’s not necessarily true.” Yin Chengjue quickly rejected Rong Yu’s conclusion: “Because, the person who could break into this abandoned laboratory at this time is most likely connected to what happened ten years ago.”
