That night, they walked from the rooftop of the next building to the building where the KTV was located, and then entered the top floor.

Since they wanted to avenge Yuan Tianjiao, they naturally did a full investigation and found out that the private room on the top floor was exclusive to Niu Mang. With Niu Mang's influence in those streets, he never thought that anyone would dare to kill him.

The two of them arrived outside the private room smoothly. Through the crack in the door, they saw Niu Mang taking off a woman's clothes. The woman was lying on the sofa and seemed to be unconscious.

"Could that woman be Hu Xiao?" Sun Yu suddenly asked.

Xiao Qi nodded, "She went to discuss business with Niu Mang. Niu Mang is a beast who can only think with his lower body. He has always coveted the boss's body. The boss didn't have his subordinates that day, so he drugged the boss."

Xiao Qi sneered, "When we saw that scene, we concluded that Niu Mang was harming women again. We were hesitant at first, but when we saw that scene, we rushed in decisively and attacked Niu Mang."

Two high school students, young and frivolous, passionate, but they were not stupid enough to actually kill someone. They originally just wanted to sneak up on Niu Mang and beat him up. This was the revenge in their hearts.

As for the switchblade, Xiao Qi only carried it with her to scare people.

When they saw Niu Mang preparing to violate a woman again, their passion finally defeated their reason.

Niu Mang is a social person, he has lives on his hands, and he is very ruthless. Facing two high school students, he quickly gained the upper hand even under the premise of being attacked by surprise.

Seeing that they could not fight, Xiao Qi and Bao Youliang chose to escape. They retreated along the original route, from the top floor to the rooftop, and then climbed to the rooftop next door.

Unexpectedly, Niu Mang actually chased him and chased him into the alley behind the building.

In the alley, Niu Mang knocked down the two men and asked them why they attacked him. When he learned that Xiao Qi and Bao Youliang came for Yuan Tianjiao, he directly admitted that he was the one who killed Yuan Tianjiao for fun.

At that moment, Xiao Qi and Bao Youliang went berserk at the same time. Xiao Qi took out a switchblade and wanted to kill Niu Mang, but Niu Mang kicked Xiao Qi's knife away.

Bao Youliang took the opportunity to kick Niu Mang in the lower body. Niu Mang was so angry that he grabbed Bao Youliang's neck with his backhand and wanted to strangle Bao Youliang to death.

In order to save Bao Youliang, Xiao Qi strangled Niu Mang's neck with his arms from behind and hooked his legs around Niu Mang's waist, making it impossible for Niu Mang to break free.

Faced with the danger of being strangled to death by Xiao Qi, Niu Mang bit Xiao Qi's arm, which is how the skin tissue in his mouth came from.

Then Niu Mang suddenly collapsed because Bao Youliang picked up Xiao Qi's switchblade and pierced Niu Mang's heart.

Hearing this, Sun Yu nodded slowly, "I understand! You and Bao Youliang teamed up to kill Niu Mang, and then Hu Xiao appeared and used her own methods to fake a vicious fight and help you avoid legal sanctions.

"

Sun Yu had studied the files on Niu Mang's case and found that the fight took place in an alley. There was a KTV not far from there, and it was indeed the one Niu Mang often went to.

Xiao Qi nodded, "We saved the boss by accident, so the boss was very grateful to us. She called someone to help us erase the traces and arranged the fight. But at that time, the scavenger was not good at handling corpses.

Not very good, it only cleaned the skin tissue I left in his mouth and ignored his throat."

"But the level of forensic medicine at that time was not very good. The police were called by the criminal police team of the Longyang District Public Security Bureau, and Niu Mang was a member of society who was involved in the case, so it was naturally defined as a fight." Sun Yu said with emotion.

Sun Yu looked at Xiao Qi, "After that, you became Hu Xiao's confidants. One of you was admitted to the police academy and entered the police system of Mengshan City, and the other helped her work as a scavenger. She knows your biggest secret.

There is no other choice."

"Haha!" Xiao Qi smiled disdainfully, "You guessed this wrong. We both followed her willingly because we lost confidence in the police and society because of Yuan Tianjiao's incident.

The method the boss used to help us erase the traces of murder was so unbelievable, it made us feel that the law is just a tool to restrain ordinary people, and we want to be that group of people who are above the law."

Sun Yu asked again: "Have you ever thought about why Hu Xiao appeared at Niu Mang's place in the first place? Yuan Tianjiao drowned and died, but she was sexually assaulted by Niu Mang during her lifetime. Why didn't the police find anything?"

At present, it can be basically confirmed that the Qi Tian in front of him is the mastermind of Song Lin's case. This person is impeccable in his work. From his mind, he should be able to think that Hu Xiao is the person who helped Niu Mang erase the traces.

"Bao Youliang and I figured it out on the third day after Niu Mang died." Xiao Qi took a sip of tea, "But we don't mind."

"Huh?" Sun Yu shook his head angrily, "You're lying to yourself?"

"No!" Xiao Qi said calmly, "The fact is that Yuan Tianjiao committed suicide by jumping into the lake. There is no evidence to point to Niu Mang, and we did kill Niu Mang. Without the boss, we would become murderers."

Xiao Qi sat up straight and looked at Sun Yu, "Don't you think it's ridiculous?"

Sun Yu didn't answer, he understood what Xiao Qi meant.

Niu Mang killed Yuan Tianjiao. Young gangsters like Xiao Qi and Bao Youliang could find out about it, but no one could identify Niu Mang.

The real murderer Niu Mang died and deserved his punishment, but Xiao Qi and Bao Youliang who killed him had to face legal sanctions. Without Hu Xiao, they would have been a tragedy.

"Sun Yu!" Xiao Qi still looked at Sun Yu, "You know, the first thing we went to was the police, but no one believed us, so it was the law that abandoned us, not us that abandoned the law."

Sun Yu lit a cigarette and took two puffs.

During the investigation of Yuan Tianjiao's suicide case and Niu Mang's case, Sun Yu did have doubts. He thought that Xiaoqi and Bao Youliang's purpose of killing Niu Mang was revenge, but he didn't understand why they didn't call the police because it was in the case file.

There is no police record of the two persons.

However, the fact is that the two called the police, but no one took notes at the time.

Xiao Qi glanced at the closed door again, and said slowly: "After that, the boss worked hard on me and trained me to be the person in charge of the scavenger. If you can catch me, you are considered a leader.

The boss won a small round, but it's a pity that the basis for your arrest was Niu Mang's death, which has no impact on the current situation."

"No, no, no!" Sun Yu waved his hands quickly. He smiled again, and his smile was extremely bright. "Think about it carefully, why I have to check every corner after I come here."

The corners of Xiao Qi's mouth trembled, and his expression instantly became serious.

"That's right!" Sun Yu was still smiling, "Without surveillance and without recording equipment, no one knows why I arrested you. My investigation into your and Bao Youliang's case was conducted in secret, so even Hu Xiao

You don't know that I arrested you because of Niu Mang's case.
