"Raven Kai, the challenge is here again." Anthony knocked on the door, leaning against the gate and looking at Ya Kai who was turning over the information, it is easy to commit a crime and difficult to investigate, in the past three days, Ya Kai has checked the information on the scene, the clues have not been fully developed, and there are new cases.

"Who is it this time?" Raven Kai didn't raise his head, he was no stranger to this kind of serial murder, and even he had done it himself.

"Ryan."

Ryan: The most murderous serial killer is none other than Ryan, with at least 150 people, and he claims to have killed 360 to 600 people, because he also traveled a lot before he was arrested, and the actual number is not recorded, but his main hunting area is still in his home country. The reason for the legendary serial killer's murder can be traced back to his childhood. He was beaten by his mother since he was a child, and one of them was even more severe and traumatic to his brain. As a result, when he was 23 years old, he forcibly stabbed his mother to death in retaliation, and was sentenced to 40 years in a psychiatric hospital by the court, and then parole was released but did not change until October 1982, the Texas police launched an investigation because they found a handbag belonging to a widow, and investigated him, but did not find evidence to prove that he was the murderer, but arrested him for possessing dangerous weapons, but he was impatient to tell his more than 20 years of murder experience one by one after arriving at the police station, Including that he had another colleague Victor (his bisexual lover, who was said to have eaten part of the body), and the reason for the murder was that the other party was unwilling to xx with him. Later, the number of dead people continued to increase, and the police once thought that it was part of his imagination, but he was able to clearly point out certain places where the bodies were hidden and the conditions of the bodies, which made it impossible to believe him. Ryan, who had warned psychiatric evaluators not to let him go and that he would continue to kill, was perhaps most shocking to the world because of his justification for his actions in court. "I like to kill people just like everyone else likes to walk, but with different hobbies. If I need prey, I just go out on the street and find one. ”

This sinister killer is one of the top ten perverts in Jack the Ripper, and is one of Raven's right-hand men.

Raven Kai came to the scene of the crime, which is where Ryan lived, and the houses here were almost all prisons, the difference was that one was free and the other was not.

Compared to Jack, his death condition is quite visible, his neck was cut open and bleeding to death, as long as it is found in time, it is very likely to be saved by Anthony's medical skills.

"It's really exciting, a demon who slaughters demons in the Demon Abyss." Raven Kai shook his head, the same painting still hung on the wall as last time, only this time the arrow hit not the crow's head, but the crow's eyes.

"Yakai, is she scolding you for being blind and brainless?" Anthony Howe let out an unceremonious sarcastic voice.

Ya Kai didn't speak, just took a deep look at the painting, left the scene, went back to the office and continued to read his information, turning in his mind, this person killed two people right under his nose, the monitor was snowflakes, and there were no fingerprints and any physical evidence of the murderer, Ya Kai hooked the corners of his mouth, this person's anti-detective awareness is still very strong, and the perfect way to commit the crime came from whom?

Raven Kai came to the seventh underground floor, which is the lowest level of the demonic abyss, where the elite police from various countries are imprisoned, and they are all defeated by Yakai's subordinates.

"Friends, it's okay." Raven Kai stood in front of the prison and looked at the seventeen men, the oldest being seventy years old and the youngest only twenty-three, among them experienced detectives or gifted policemen.

"I heard that you were tricked, hehe, even you are not in a hurry, it is really happy." The one who spoke was the youngest boy, named Allen, who was extremely talented, and like Anseong, he was the best student of the police freshmen in their country, and he was sent to war by Yakai, and the case he participated in at that time was a serial murder case, and the murderer was Ryan.

"Want to know how we know? Hehe, that guy came to us, Yakai, can you win this time? I'm also looking forward to seeing you look downcast. "Alan is young and has been locked in for less than a year, so his blood and temper have not been worn away.
