vs？ Xie Rin looked at the familiar fonts on the wall, and seemed to be able to see through those fonts the arrogant and indifferent face of the man who didn't care about anyone, not even human life. It seems that to him, all living beings are like dogs, and lowly as ants.

"A pervert beyond human comprehension, a mad fellow." Ye Yan turned sideways to look at the young man standing outside the pool of blood, with a gentle smile on the corner of his mouth, "You are a natural criminal, you can never use science to explain his thoughts and behaviors. ”

His voice immersed everyone in the rational minds occupied by the bloody scene in front of them, and they came back to their senses from the boundless horror of their imaginations.

The forensic doctors in the back tried to avoid destroying the scene, and moved closer to the body on the ground step by step. Other police officers also began to scrutinize and collect evidence.

Looking around the entire chaotic murder scene, Xie Rin raised his foot and was about to walk to where Ye Yan was, when the tip of his shoe touched something.

Looking down, he saw a syringe rolling around the ground before rolling back to his feet.

He took the plastic gloves and ziplock bag handed by the police officer behind him, half-squatted down, picked up the syringe and put it in the bag, glanced at the light, and handed it to the forensic officer on the side.

"This is a murderer who is even more terrible than Chen Feng." Xie Rin straightened up and walked to Ye Yan's side, "Whether it's IQ, the way of committing the crime, the method of killing, or ...... Force. ”

"Poison Eye is a veteran, and with his physical strength, it is impossible for ordinary people to kill him so easily, unless he is also specially trained and the force is above him. And ......"

He paused, glanced at the corpse on the ground, and continued, "The mortal wound is in the front of the neck, and the dead cannot be defenseless, unless his killer strikes fast enough for him to resist." ”

"Very good...... "The gentle man listened to his analysis of the Tao and praised it rarely, "It seems that you have learned a lot in the past two years." ”

Someone's tone of having a child in my family made Xie Rin's face darken, and he glanced at him coldly.

"The murderer killed for the first time, simple and crude, with a single means and a clean scene; The second killing, a knife mistake, and the first skin is speculated; And this third murder seems to have triggered the thirst for blood in his heart, making the scene even bloodier than the previous two times, and ......"

As he spoke, the man's eyes under the lenses darkened a little, and he spoke unhurriedly, "I just studied the deceased's chest and abdomen, and his heart was taken out. ”

Have you ever been taken out? This sentence made Xie Rin's eyebrows jump, and when he came in, he didn't see the heart he said at the scene, he looked at him hesitantly.

"You mean, he took out the heart of the dead and put it back in?"

"That's right." Ye Yan bowed his head and said in a long voice, "In addition, he probably became curious about another way of killing......

"Another way to kill?" Suddenly felt a little pain in his temples, and Xie Rin's throat was so dry that it took him a long time to say two words.

"Heartbreaking!"

That's right, it's dissecting, if he's not wrong. Ye Yan thought that this person never did meaningless things, and if he did, it would mean that he had other strange and novel ideas.

For example...... When I cut open the chest of my prey, I happened to see the heart inside him, and I suddenly became curious about the shape or color of his heart, which cannot be ruled out......
