Ms. Quan, who is male

The moment he saw the butterfly, Quan's first reaction was not nervousness or fear, but curiosity, how did he get marked?

If it was contact, when the victim fell down just now, he avoided it in time and should not have been touched.

Next to him, Kunikida Doppo Mizumi was silent for a long time, feeling uneasy and asked: "What's wrong? Could it be..."

"Yes, I have it too." Quan responded calmly.

He touched the butterfly wing on his collarbone and found to his surprise that it could not be wiped off. In addition, he did not feel any discomfort on the skin with the butterfly pattern printed on it.

This pattern appeared silently, and the strangest thing was that Kunikida Doppo couldn't even see this thing.

"So, only the marked objects can be seen? That's really funny."

A familiar voice came from behind. Quan looked through the car's exterior mirror and saw the bandaged arm.

"Oops, I hate touching corpses." Dazai Osamu complained, squatting next to the office worker's corpse, and stretched out a finger to touch the place circled by the spring with the butterfly mark.

His fingers just passed by like a dragonfly, but the purple butterfly imprinted on the victim's neck melted away as quickly as snow under the scorching sun.

Quan, the only person present who could see this change, told them: "The pattern is gone."

This proves that the purple pattern is indeed some kind of superpower.

In addition to the disappearance of the purple pattern, the body spots on the victim, who seemed to have nothing unusual except for a stiff body and a dull expression, appeared at a speed visible to the naked eye.

Based on the temperature and humidity as well as the distribution of rigor mortis and body spots, Osamu Dazai roughly deduced that the victim died six to eight hours ago.

"So, it is now basically certain that the purple butterfly Izumi saw should be related to the reason why the victim died in an unnatural state after death in this case." Kunikida Doppo pushed up his glasses, glanced at Izumi, and then

He said to Dazai Osamu who was squatting on the ground, "In that case..."

"Kunikida-kun, do you want me to use the human disqualification to remove this mark on Sister Koizumi?" Osamu Dazai turned his head and glanced at Izumi's shoulders and neck. He didn't see any purple butterflies, then stood up and looked at his partner.

"What?" Kunikida frowned without any trace. After saying this, doesn't Dazai Osamu not want to remove this mark from Izumi?

"However, we now know that this unique superpower mark can only be seen by the person who is marked. So, Kunikida-kun, have you ever thought about whether this mark will appear next if you remove Izumi's superpower now?

A victim? And who could it be?"

Osamu Dazai gave his guess in a clear and logical manner.

"..." Kunikida Duppo frowned, "But we are also unsure about the conditions and time for the onset of this supernatural power, right? Doesn't this put Izumi in danger?"

Quan's eyes glanced back and forth between the two of them, and finally looked at the victim lying on the ground, and said: "What I'm curious about is, did the victim die directly due to the influence of supernatural powers?"

Osamu Dazai glanced at him: "Are you talking about the direct cause of death? It was suffocation."

"Suffocation?" Quan carefully observed the condition of the victim's body and found that his face was swollen, bruised and cyanotic, which were indeed the physical characteristics of suffocation. Because of rigor mortis, Quan could not open his jaw to check his body.

Did the teeth bleed? However, Dazai Osamu would not fool him on this matter, so he did not dwell on the cause of death.

"The autopsy reports of the first three victims showed that there were no foreign objects in the victim's respiratory tract, and there were no suspicious marks on the neck or face. In addition, carbon monoxide poisoning was also ruled out. Finally, there was no damage to their central nervous system, and their nerves were

The adjustment function is all normal, so it is not pathological asphyxia.”

Osamu Dazai said calmly.

"I now suspect that the prisoners used supernatural powers to manipulate the victims, making them unable to struggle or move, and then covered their faces with airtight fabrics or heavy winter quilts to cause mechanical suffocation."

"In this way, the victim's neck, face and other local areas will naturally not leave any suspicious traces such as strangulation marks. Then use superpowers to cover up the condition of their corpses and manipulate them to appear within the surveillance range like normal people.

.The true condition of the body, together with the time and manner of the crime and the manner of the murder, were all covered up under false illusions. It is undoubtedly impossible for the police to find the culprit through conventional methods."

"In short, your guess is that this kind of supernatural power cannot directly kill people. It is the prisoner himself who really does it." Quan nodded, "I understand, you want to use me to fish out the prisoner hiding behind him."

Osamu Dazai smiled and added: "Our investigation found that the three previous victims were all single and living alone."

Quan: "This also gives the prisoner an opportunity to take action."

Osamu Dazai: "Do you also prefer the party where the criminal comes to the door?"

Quan: "After all, there are more variables outside, right? It's hard to say for non-breathable fabrics, but every household should have a quilt, right? In this way, it is naturally more convenient to commit the crime at the victim's home. In addition, when the victim is found, all of them are fully clothed.

Neat and well-dressed. This shows that the prisoner is a very ritualistic guy, who will sort out their remains and put on clean and tidy clothes. Therefore, he should come to the door in person to handle the follow-up."

Dazai Osamu: "But who can avoid the eyes of neighbors and enter and exit the victim's house freely?"

Quan: "Takeaway person, courier person? Considering the time it takes to stay at the victim's home to commit the crime...it would be more appropriate to be a repairman or housekeeper."

Dazai Osamu: "Sure enough, Sister Koizumi thinks the same as me~"

"But having said that." Izumi narrowed his eyes and looked at Dazai Osamu suspiciously, "Since you have been able to lock the target, why don't you catch the prisoner?"

"We were searching just now, but we didn't find the criminal, but found the fourth victim. And..." Osamu Dazai glanced at Izumi's neck, blinked innocently and said, "I think you're lucky now.

, we don’t have to go to each other, the other party can deliver it directly to our door.”

"..." This is the second guy after Uchiha Izuna who blatantly uses him as a tool and takes it for granted.

Quan looked at him expressionlessly: "I even feel that I am about to become a non-staff member of your detective agency?"

Dazai Osamu smiled: "Isn't that great?"

Kunikida Doppo: "...?"

Wait a minute? Why is he listening...This case is over like this???

"But there is still one problem that remains unresolved." Izumi looked at Osamu Dazai with deep eyes, "How did he mark the target?"

"Well, well..." Dazai Osamu protracted his voice, "Since the goal he chose is to live alone, there must be a chance to confirm it in advance, such as..."

"Have you ordered takeout lately?"

Not long after, the police arrived at the scene and took away the body of the fourth victim.

Quan picked up the broken mobile phone and waved goodbye to the detective agency.

He took a leisurely walk back home and called the restaurant he always ordered for delivery - if he didn't want to cook, he would have to eat takeout.

After that, he put on his fluffy home clothes and lay on the sofa watching cartoons.

About an hour later, the doorbell rang at home.

Quan threw away the remote control, walked to the door, and used the doorbell to tell the other party to leave the takeout at the door. Since encountering a door-opening murder, Quan would ask the restaurant delivery person to leave the food at the door every time he ordered takeout.

The delivery boy who often delivers food to him is probably used to it. After leaving the dinner at the door as requested by Quan, he left without stopping.

Quan made sure through the peephole that no one was outside, and then opened the door to pick up the food.

He put the pizza box on the glass table in the living room and was about to wash his hands. But on the way to the bathroom, he suddenly stopped like a robot that pressed a button to pause. Even the foot that had just been stretched out was still there.

Didn't have time to land.

However, this abnormality did not last long, and the "frozen" spring quickly returned to normal.

He did not continue to the bathroom, but walked to the floor-to-ceiling window in the living room and closed all the thick curtains, completely cutting off the two worlds inside and outside.

The light in the living room suddenly became extremely dim. Quan had no intention of turning on the light and just sat quietly on the sofa.

At this time, the doorbell rang.

Quan got up and walked towards the door.

Different from the caution he used when getting takeout before, this time Quan seemed to have completely forgotten to check who was outside and just opened the door.

The guy standing outside was a middle-aged man dressed as a repairman. He was wearing a hat and strong and durable overalls. He was holding a toolbox in his hand and said with a simple smile: "You are the one who called me to come.

Can you help fix the water pipes?"

The expressionless Quan nodded, then turned around and walked in without saying a word - if he hadn't looked at those frightened eyes, maybe there really wasn't anything unusual.

The repairman standing outside quickly followed and closed the door.

Quan led the repairman into the dimly lit living room, went to the bedroom to get a quilt, and lay down on the floor to cover himself.

The repairman let out an unknown chuckle, put down the tool box in his hand, and was about to go to the bedroom to get the clean clothes he would change into later, but who would have expected...

There was a "ZilaZila" sound of electricity, and the lights in the living room suddenly lit up in a flash.

The repairman was shocked.

"who?!"

The room flickered with light and darkness. The repairman quickly looked around, but found no one at all.

He suddenly thought of something and subconsciously looked at the floor - the quilt and the person were still where they were, which made him sigh in relief.

But when he took a closer look, he felt something strange. Quan was obviously a petite person, but for some reason, he felt that the guy lying under the quilt seemed to be bigger than Quan just now.

Several laps.

The repairman felt uneasy, couldn't help but swallow, squatted down, and carefully opened a corner of the quilt.

When he saw clearly who was under the quilt, his pupils suddenly trembled and his face suddenly turned pale.

Because... the person under the quilt turned out to be himself!
