Chapter 70

"Is there a butterfly in Meng Changshou's mind?"

"Doctor said that the leader's brain developed abnormally, with early permanent damage, a rare case of a psychological deviant's brain." Every word from Meng Changxi was filled with a chilling aura: "It was only at that moment that I realized that the one who was sick in my family was not just that beast, but also the eldest brother who had always taken care of me and helped me."

"So, Meng Changshou is the butterfly?"

Han Fei was very surprised, and Meng Changxi was even more surprised when he heard Han Fei's words: "You actually know about the butterfly's existence?"

"I only know that Meng Chang'an has been looking for the butterfly, but I haven't figured out what the butterfly is exactly." Han Fei was fully focused, preparing to remember every word Meng Changxi said.

"The eldest brother is not the same person as the butterfly we are looking for, but the butterfly did indeed change the third brother through the eldest brother." Meng Changxi revealed another piece of information: "When the third beast was in school, he became even more insane, and the treatment had no effect at all. At that time, the eldest brother, who was already working, found a psychologist for the third brother. After seeing the brain scan of the eldest brother, I realized something was wrong. I traced back based on the information left by that doctor, but the information and the person did not match. The one who had been treating the third brother was not a psychologist, but something else."

"Something else?" Han Fei noticed Meng Changxi's choice of words.

"Yes, I don't know how to describe it, but it doesn't seem to be human." Meng Changxi rolled up his sleeve, revealing scars on his arm that looked like codes or text: "I saw it clearly, but I can't remember its face. To avoid forgetting the last bit of memory about it, I recorded everything on my body."

Looking at the scars on Meng Changxi's arm, Han Fei's eyelids twitched: "You are really tough on yourself."

"Before meeting you, I had no other way out." Meng Changxi pointed to his face: "Now, there are cameras everywhere, connected to the central AI. As long as a suspect's face appears, it might be recognized. To avoid being caught, I disfigured my face."

The grotesque scars on his face made it impossible to tell if Meng Changxi was crying or laughing: "That thing always treated the third brother at night. It compared the human body to a nest for the soul, believing that the soul gives form to life and transforms the potential of the body into reality, a process that is the essence of life."

"I don't quite understand this. Can you simply tell me what the thing's characteristics are? I want to catch it and avenge my friends." Han Fei's words were simple and sincere.

"To be specific, that thing has butterfly wing-like patterns on its arms. I can't remember its face, but I remember the patterns." Meng Changxi then revealed something very important: "They seem to be looking for a box, a box filled with the world's pain, despair, and misfortune. That box is hidden deep within the soul. It initially tried to find the box in the third brother but failed."

"A box?" Hearing this, Han Fei was already certain that the butterfly's target must be the black box in his head.

"That box seems to appear in the most unfortunate people. The butterfly searched for a long time without finding it, so they decided to create a soul that might contain the box." Meng Changxi took off his coat: "Ten years ago, the butterfly targeted three people, all of whom were the killers in the human puzzle case."

"Three?"

"The first was He Shouye, the director of the North Street Orphanage. The second was Meng Chang'an, and the third was my eldest brother. I know of these three, but there might be other killers."

"Do you have any concrete evidence?" Han Fei wanted to help Meng Changxi, but he also knew that if there were any substantial evidence, Meng Changxi wouldn't need to hide.

The two men in the room fell into silence, neither speaking.

After a few seconds, Meng Changxi pressed his lips together and slowly said, staring at Han Fei: "Can I trust you?"

"Of course."

"Don't agree so quickly. You don't know me. I killed He Shouye. The person standing in front of you is a real killer." Meng Changxi's scarred face, combined with his words, was terrifying.

"I already guessed as much, so I hope that after we catch the real killer, you will turn yourself in and seek leniency." Han Fei had seen too many terrifying and bloody scenes; his reaction was not what a normal person would have when with a killer.

"I don't have concrete evidence, but I have organized everything and placed it in an abandoned neighborhood on the outskirts. The place is called Happy Neighborhood, and all the evidence is in the bathroom of room 1044." Meng Changxi slowly shifted his gaze: "The police will soon find me. When Meng Chang'an killed, he deliberately involved me. I don't have much time left."

"The place you mentioned..." Han Fei was really shocked when he heard Meng Changxi's words. The haunted house he lived in in the game was also room 1044.

"What's wrong?" Meng Changxi was puzzled by the change in Han Fei's expression.

"Nothing, I'm just surprised that you had contact with the victims in the human puzzle case. I heard that the police only received videos of you burying animal and human bodies in the past. If Meng Chang'an had evidence of the human puzzle case, why didn't he..."

Han Fei was interrupted by Meng Changxi: "Sending videos of me burying animal bodies to the police is not something Meng Chang'an would do. He had already placed the clues and evidence where the police would find them during a thorough investigation. He wanted the police to catch me personally."

"Who sent the videos?"

"That's not Meng Chang'an's style. It might have been the eldest brother." Mentioning Meng Changshou, Meng Changxi was even more distressed: "I don't know what kind of connection exists between those people influenced by the butterfly. Compared to Meng Changshou, Meng Chang'an is closer to the butterfly's requirements. If something really happens, I suspect the eldest brother will take the blame for Meng Chang'an. They seem to have another backup plan, which is why I didn't dare to reveal the information I organized."

"You are entrusting the information you organized to me. What do you plan to do yourself?" Han Fei realized that Meng Changxi seemed to be entrusting his legacy.

"You don't need to know what I plan to do. Just remember the address I gave you." Meng Changxi's eyes were fixed on Han Fei: "If I die, give the things there to the police."
