Villain: Without Morality, You Will Not Be Kidnapped!

While Qi Lin was immersed in thinking, a young police officer in police uniform came over and asked eagerly: "Sir, are you Mr. Qi Lin? We are in urgent need of your help.

Qi Lin nodded and replied with a smile: "Yes, I am. Please tell me the details of the case.

The police officer began to introduce the case in detail to Qi Lin. From his mouth, Qi Lin learned that the fire occurred at about three o'clock in the morning, the cause of the fire was still unknown, and the body of a suspected arson suspect was also found.

Qi Lin thought for a moment, then waved his hand to signal the police officer to leave. He stayed at the scene alone and began to investigate using his own special methods.

First, Qi Lin walked around the apartment building and carefully observed every corner. He noticed that there was a cave covered in black paint on the wall of the hall. This aroused his great interest.

Qi Lin took out his flashlight and carefully illuminated the cave. His eyes gradually focused and found some tiny traces: charred wood fragments and some charred clothing fibers.

"This cave was deliberately covered, and traces showed that a fire broke out inside." Qi Lin secretly speculated.

Next, Qi Lin turned around and left the hall, heading to the top floor of the apartment building. There, he discovered another suspicious clue. One of the glass windows was completely shattered, and there were traces of flames on the railing outside the window.

"It seems that the fire started to spread from here." Qi Lin narrowed his eyes and thought, trying to restore the entire process of the case.

Just as Qi Lin was contemplating, a gust of wind suddenly blew by, bringing with it the smell of smoke. Qi Lin suddenly became alert and immediately walked towards the window. He looked carefully at the ground near the window and found some ashes and residual burnt matter.

"It seems that the fire started from this window." Qi Lin made a preliminary judgment in his mind.

As a result, Qi Lin began to look back at the scene before the case. Through careful observation and reasoning at the crime scene, he came to a preliminary conclusion: the arson suspect deliberately broke the top-floor window, causing the fire. The caves in the hall walls may have been used as a test site before the arson attack.

Next, Qi Lin decided to have in-depth conversations with relevant personnel in order to learn more details about the case. He found the security guards, residents and witnesses in the building, and asked ten of them.

While talking with the security guard, Qi Lin discovered that a security guard behaved abnormally, with flickering eyes and nervous speech... This aroused his suspicion.

"Can you tell me what you did when the fire broke out?" Qi Lin asked bluntly.

The security guard hesitated for a moment, then replied: "I... I was on patrol and didn't see anything suspicious."

Qi Lin stared at the security guard expressionlessly. He could feel that there were inconsistencies in the other person's words. So, he decided to start from another angle.

"Can you tell me your first reaction when you discovered the fire? Is there anything strange that attracted your attention?" Qi Lin continued to ask with a smile.

The security guard's eyes began to wander, and he replied in a panic: "I, I remember that someone moved near the window."

Qi Lin's heart moved, and he was keenly aware of the contradictions of the security guard. This discovery further deepened his suspicion of the security guard.

Next, Qi Lin found a resident of the apartment building who lived near the hall where the fire occurred. After some questioning, Qi Lin learned that the resident had heard strange sounds coming from the wall of the hall, as if someone was moving inside. .
