After killing Dominic, Pang Jindong finds Barney and Al fighting beside him. Al lay on Barney's back, his legs wrapped around Barney's waist, and his hands tightly around Barney's neck.

Barney looks like a wolf, and he can't do anything to Al because of his physical strength. He kept shaking his body, but he still couldn't shake Al off his body. El was like a leech, clinging to Barney's back.

Pang Jindong came behind Al and told him: "Listen, we Chinese are not monkeys! In fact, when our ancestors created the zào civilization, your ancestors had not climbed down from the trees!"

Before Al could react to Pang Jindong, Pang Jindong twisted El's cervical vertebrae as if he had killed Dominic.

Barney threw Al's body to the ground, stomped on it a few times, then shook his neck a few times, and said to Pang Jindong, "Thank you!"

Pang Jindong didn't answer, but looked at the others. At this point, everyone has already decided the winner, Meryl kills Lis, and Kane kills Lisa, who is already on the verge of death.

"I'm sorry she rushed over and attacked me...... That's all I can do......" Kane said in a low voice as he looked at Lisa's corpse.

Suddenly, with a squeak, the lid of the metal box opened automatically, revealing four blue syringes in the middle.

"How do you use this thing?" Meryl said breathlessly, she didn't win the fight just now.

"Like me!" Pang Jindong picked up a syringe, pinched it at the bottom, and then quickly stabbed it into his arm.

The others did the same, and then everyone sat down on the ground to rest. After what happened just now, everyone seemed to have an extra layer of separation between each other, and no one was willing to take the initiative to talk to others, but they paid attention to everyone. Even if there is a small movement of the people around you, you have to watch nervously for half a day.

At this moment, the voice sounded again: "Congratulations on passing the test! Please continue the journey, more difficult tests are waiting for you!"

The words landed, and the iron door slowly opened. The group walked through the iron gate and found a corridor ahead.

No one thought about what the voice had just said meant by "a harder test", and they hurried away, trying to leave as much as they could. It's no longer because of the fear of the place, but because you don't want to see anyone killed by your own hands anymore.

"Come and see here!" Meryl had just walked to the front when she found a room with an open door on the right side of the hallway, and the light inside was bright, illuminating the nearby hallways very clearly.

Several people walked into the room and were immediately stunned.

The room is very spacious and has a lot of equipment. Horrifyingly, there was a man lying on a bed, his head plugged in with various wires and instruments, which were connected to a device not far away.

It was a middle-aged man, his limbs fixed to the bed, his eyes closed, but his expression was very serene.

Pang Jindong walked to the man's side, felt his pulse, and found that he was still alive. Then, Pang Jindong pushed him, but the other party didn't react at all. Pang Jindong then pinched him again, but there was still no reaction at all. In the end, Pang Jindong was sure that this person would no longer react to anything outside world.

"I think he's dead!" After a pause, Pang Jindong continued: "To be precise, brain dead!"

"You're right!" Meryl pointed to the various instruments around the man and told everyone, "This is a pacemaker, and there are also auxiliary breathing devices, all of which are used to maintain his physiological functions!"

Kane frowned slightly and asked, "What is this machine for?"

Pang Jindong noticed that the machine was connected to a plotter, and many charts had been printed. Pang Jindong picked up these charts and looked at them patiently, and found that they were all kinds of waveforms, such as brain waves.

"I think this should be used to clear memories!" Pang Jindong said as he examined the charts.

"Oh my God!" Meryl covered her mouth with her hand, as if to prevent herself from screaming.

"Can we recover our memories through guò?" Barney asked.

"I don't think so! For example, guns can kill people, but have you ever seen that they can save people?" Mr. Pang said. After a pause, Pang Jindong asked Kane: "Kane, what's your last name?"

"Patrick!" Pang Jindong's sudden question made Kane feel a little inexplicable: "Is there any problem?"

"Nothing!"

"What are we going to do next?

"No!" Pang Jindong shook his head and said thoughtfully: "First of all, we must figure out one thing!"

Kane asked, "What?"

"I have a total of eight charts here, which means that this machine has been used a total of eight times!"

"What does that mean?" Barney shrugged his shoulders, looking unconcerned.

But Meryl immediately thought of it, and she said to Barney, "You don't understand, we originally had eight people, plus the one lying here, that's nine people, but this machine has been used eight times in total!"

That is to say...... One of us has been lying!" Barney was a bit stupid, but he couldn't ignore the obvious.

"Yes!" Pang Jindong said, his gaze sweeping over everyone's faces. "There are spies among us!"

Pang Jindong's words stunned everyone.

"But who could it be?" Meryl said, spreading her hands, looking surprised. "It's not me anyway!"

"How could it not be you?" Barney looked at Meryl and clenched his fists with both hands, "How do you know what kind of breathing aid device you have?"

"I ...... I don't understand why I know ......" Meryl began to panic as Barney kept closing in on her, "It's really not me......"

"Barney, trust me, it's not Meryl!" Pang Jindong put his hand on Barney's shoulder and shook his head at him.

"Is it me?" asked Barney.

"It's not you, it's not me!" After a pause, Pang Jindong turned to Kane and asked, "Who are you?"

"You...... What are you talking about? I'm with you!" Kane said with a look of surprise on his face.

"Kane, who the hell are you?"

"Why him?" Barney asked curiously.

"First, there are three ladies among us, and it's normal for Meryl and Liz to be in a group, but the extra Lisa was placed in a group with Kane, and Kane was too lucky. ”

"What does that mean?" Kane shrugged.

"We were all poisoned, and the crux of the matter is that Lisa was the first to get sick, and the other two ladies didn't come so quickly, which means that Lisa may have been poisoned earlier than us, why? Because someone needs to keep Kane safe! Even though it's not a lady, Kane doesn't want to risk his life, right?"

"You...... This is a slander with no evidence!" Kane looked very angry.

"Second ......" Pang Jindong said, taking out an ID card to show everyone: "This is what I just found under this person, and he is the real Kane Patrick." ”

"You believe in a piece of identification, but you don't believe me?" Kane asked.

"I'm sure no one will forge identification for a dead person, and given the first point, I can only doubt you!"

Kane looked at Pang Jindong, and after being silent for a long time, he suddenly lowered his head and whispered, "It's still known to you!"

"Sure enough, it's you!"

"Actually, I wanted to help people ......"

"So we're going to erase our memories?"

"Your business has nothing to do with me, but I did invent this machine. I would have figured out that this machine would clear people's bad memories and help criminals and addicts, but ......"

"But the machine is out of control, isn't it?"

"Suffice it to say, because I found that this machine can't selectively erase people's memories for a specified period, only completely. What's even more terrifying is ...... In a misguided operation, it directly led to Kane Patrick's brain death, leaving the poor victim to live on life support......"

"What's your real name?"

Kane sighed, smiled, and replied, "Dr. Hauge." ”

"The questions are going to come one by one, and then please tell me, who are we, and why are we here?"

"I don't know the answers to these questions......"

"So what do you know?"

"I knew that I had spent ten years developing this machine, but when it was successfully developed, the flaws were exposed, and my superiors cut my budget for it. Actually, if I was given a little more time, I could have done the improvement, but that bastard wouldn't give me a chance!" At this, Dr. Hauge became agitated: "I asked him to reason, but he told me to pack up my things and leave, so I ......"

"So you killed him?"

"That's right!" Hauge at this time put away his gentle and elegant appearance, and his expression became fierce and violent: "He deserves to die, I never regret killing him!"

"And then?"

"And then I was arrested by the police, and someone came to me and told me that he had a way to save me from being held accountable, but to involve me and my machine in a plan!"

"That's all about us?"

"Yes! Those people asked me to clear your memories, and then hide among you, and go through this qiē with you! God testifies, my life is not easy either!"

"It's the reason you invented this harmful machine that got us trapped here!" Barney became, getting angried, and went over to grab Dr. Hauge.

"Wait, Barney!" Pang Jindong stopped Barney, and then asked Dr. Hauge, "What is the purpose of the plan?
