Villain: Without Morality, You Will Not Be Kidnapped!

"Thank you, Detective Qi." The family members burst into tears, "You gave us justice.

Qi Lin smiled faintly and said: "I just did what I should do." In his eyes, this is just his job and his responsibility. What he can bring to himself is inner peace and satisfaction.

Thick smoke billowed and flames roared. Qi Lin stood at the edge of the fire, staring at the ruins. He is a detective, and he came to the fire scene this time to investigate a vicious arson case.

"Qi Lin, what do you think?" Ji Luo, the police chief next to him, asked him.

"Arson cases are generally driven by profit, revenge, and cover-up of crimes. We need to investigate them one by one." Qi Lin's deep eyes showed determination.

"Judging from the scene, the source of the fire should have started from the first floor. Let's go there and have a look." Qi Lin walked toward the ruins, followed closely by Li Luo.

In the ruins, they found some remaining items. Qi Lin bent down and picked up a burnt doll. Its face was so blackened that its original appearance could no longer be seen.

"This doll may be our only clue." Qi Lin said thoughtfully.

In the next few days, Qi Lin and Li Luo launched an in-depth investigation. They visited the victim's family, neighbors, and friends to try to find possible suspects and motives.

"Did the victim have any enemies during his lifetime?" Qi Lin asked.

"As far as we know, the victim is an honest man and has never heard of any enemies." Li Luo replied.

"Then has anyone had conflicts with him recently?" Qi Lin continued to ask.

"Well... there was a man named Wang Gang who had a quarrel with the victim. But he said he just had a quarrel with the victim and never made any move." Li Luo said hesitantly.

"Wang Gang..." Qi Lin muttered the name silently, with a strange flash in his eyes. He decided to talk to Wang Gang.

At Wang Gang's home, Qi Lin had a conversation with him.

"You said you just had a quarrel with the victim?" Qi Lin asked, staring into Wang Gang's eyes.

"Yes...yes, I just had a quarrel with him. I didn't set the fire!" Wang Gang replied nervously.

"Then can you explain why (ccbd) there are ashes left by the fire on the soles of your shoes?" Qi Lin took out a pair of shoes with ashes on the soles and placed them on the table.

Wang Gang looked pale and straight.

"It seems that you can't deny your crime." Qi Lin said coldly, "Tell us, why did you set the fire?"

Under Qi Lin's questioning, Wang Gang finally broke down and told the truth: "I...I just wanted to teach him a lesson, but I didn't expect the fire to burn so big..." He covered his face and cried bitterly, "It's too late for me to regret now..."

"Regret? Can your regret bring back the safety of those innocent lives?" Qi Lin asked sternly, "You must pay the price for your crime!" After saying that, he turned and left the room.

The police who had been waiting outside the door immediately took Wang Gang away for investigation. After further review of the case, his guilt was confirmed and he was punished accordingly.

One day, Qi Lin received an emergency call from the police station, telling him that another arson case had occurred. He quickly rushed to the scene and found that the entire building had been engulfed in flames and filled with thick smoke. Qi Lin put on a mask and carefully searched the fire scene.

Through careful observation and analysis, Qi Lin discovered some abnormal traces. He saw a burnt wire and a melted candle. This made him curious. Because these are not the tools commonly used by arsonists.
