In Inspector Megure's opinion, even if the criminal's methods were restored, it would make a huge progress in the entire case, but there would be no way to identify the real culprit.
But for Tang Ze, this is not a difficult problem.
Because he already knew the context of the case, the cause of the whole case and the murderer.
Ayako Yumekawa, the person who reported the case, is the murderer in this case, and her motive is the same as the murderer restored by Tang Ze.
She, the deceased, and two other boys who had not yet been killed were friends in the game. She told the three of her criminal methods and asked them to experiment at home.
After they experimented with their own doors, they all succeeded and praised her for being so amazing.
She was very happy and thought that she could use this method to curry favor with a well-known screenwriter and establish a good relationship with him.
But who knew that the deceased Atsushi Morita wrote this technique into her novel without her consent and uploaded it to the Internet.
She asked Morita Atsushi to delete it immediately, and in excitement she pushed her. Unexpectedly, she fell and hit her head on the sink, and then lay motionless.
Simply put, this was a murder in the heat of passion, and Ayako Yumekawa had no intention of killing at all before this.
But since she had designed a good secret room, she chose this method in a hurry to escape the crime.
But there is a flaw in using this method, that is, the other two game friends know about this and know that she is the one who figured out the secret room.
If they told the police about this, and the police found that the method of death described by Morita Atsushi was consistent with what he had said, and combined with what the two said, they would definitely know that there was a conflict between the two.
So in order to prevent herself from being exposed, Ayako Yumekawa killed the other two people using the same method.
This is the whole story of this case.
It is also very simple to break the deadlock. As long as we follow the clues to find out the news, the follow-up things will be easy.
Thinking that the other party would continue to commit crimes, Tang Ze did not hesitate or delay. While everyone was still investigating the crime scene, he went to the other party's bedroom.
The other person lived alone and there was no password set on his computer, so Tang Ze opened the computer easily.
As for the key game, Tang Ze hacked into the computer using [Detective] and logged into the game easily.
He looked at the friend list in the game and found that there were three people in total, one male and one female who were not online, while the other male account was in the game.
Shortly after Tang Ze contacted the other party, he immediately received a reply, and the other party invited him to join a team to play.
However, Tang Ze immediately revealed his identity, explained the situation, and left his phone number, hoping that he could contact him.
Not long after, a strange phone call came in. Although the other party was skeptical, after Tang Ze took Takagi and drove a police car to the other party's home, the otaku named Kiryu Taiji believed it all at once.
After Tang Ze deliberately guided him when he asked, Taiji Kiryu immediately matched the death of the deceased with the method she had come up with and told the story.
"Who has this technique been told to?!" Takagi asked immediately after hearing this.
"Besides me, there's Yumekawa Ayako and Sugasawa Koreji, and only the three of us know about it." Kiryu Taiji said truthfully.
"I understand. Thank you for your help." Takagi thanked the other party and said goodbye.
As soon as they got in the car, Gao Mu immediately said, "This is a big discovery. If this is true, then Yumekawa Ayako is a major suspect!"
"That's true, but if you want to convict her, you need solid evidence."
Tang Ze said, "Have someone keep an eye on these three people. Since the criminal used a method known only to them, they will definitely try to silence him in order to avoid exposing themselves as the real culprit."
"I understand!" Takagi nodded and immediately contacted Inspector Megure, telling him about their findings and asking him to arrange manpower.
They said they were keeping an eye on these three people, but if Taiji Kiryu was the criminal, he would definitely not reveal such important information. After all, that would undoubtedly be walking into a trap.
Sugasawa Koreji runs a bakery, so his alibi is clear.
In addition, after their investigation, they found the deceased's novel, which used the techniques of Ayako Yumekawa, so they basically locked in Ayako Yumekawa.
So they kept a close eye on Ayako Yumekawa and protected the other two, waiting for the criminal to commit another crime.
As for Tang Ze, who was guiding the development of the situation, he simply became a hands-off boss at this point and didn't care about the matter at all.
After all, he was the one using his brain, and now all that was left was to finish the manual work, so naturally he didn't need to worry about it anymore.
Moreover, Tang Ze let go very thoroughly, because before Yumekawa Ayako was arrested, he knew that there would not be a second case.
So he took Ayako on a spontaneous trip. This time, the two of them went to Shikoku for a week. Then on the third day after returning home to rest, they received news that Takagi and others had arrested Yumekawa Ayako, a criminal in the act.
It can be seen that Ayako Yumekawa is quite patient. She committed the second crime ten days after the first one.
Unfortunately, they had already protected the two of them ten days ago and were closely watching her every move.
When she went to Yasuji Kiryu's house to commit the crime, the person in charge of guarding her immediately notified the criminal responsible for Yasuji Kiryu's safety.
He went straight to the other party's house and hid there. When she took out the electric baton she had prepared to attack him, he caught her in the act.
At this point, the case finally came to an end.
