Villain: Without Morality, You Will Not Be Kidnapped!

Qi Lin is a well-respected detective known for his intelligence and calmness and decisiveness. He is always able to find clues in the most difficult situations and uncover the truth of the mystery. This time, he faced an arson case.

The case took place in a five-star hotel located in the center of the city. The entire building was engulfed in flames, with black smoke billowing and dark clouds gathering. Qi Lin rushed to the scene quickly. He was wearing a black suit and sunglasses and looked very calm.

"Mr. Qi, welcome to your arrival!" Wang Li, the criminal investigation section chief of the police, greeted him eagerly in protective clothing.

"Chief Wang, is there any new progress?" Qi Lin asked.

"We have confirmed that the fire was caused by arson. But 873 is that we have not found any evidence that can point to the suspect.

"I want to know more about the details of the case. Can you provide me with some information?" Qi Lin asked.

Wang Li handed Qi Lin a document that recorded the cause, process and on-site investigation results of the fire. Qi Lin read it carefully, with a thoughtful expression on his face.

"According to the report, the fire broke out at about two o'clock in the morning. There were no casualties, but the hotel suffered huge losses. I want to know if there are any witnesses?" Qi Lin asked.

(aifg) Wang Li shook his head. "Unfortunately, we have not yet found any of the tasers. This makes our investigation even more difficult.

Qi Lin frowned deeply. His intuition told him that this case was not simple. He decided to start the investigation again from the scene and look for clues that might have been overlooked.

He walked through the charred doorway and entered the hotel, which had been cordoned off. Among the wreckage, he found a cigarette butt. He carefully put it into a plastic bag and marked it with a number.

Next, Qi Lin came to the guest room on the floor where the incident occurred. He carefully inspected each room, looking for any suspicious signs. Suddenly, he noticed a mark on the wall. He came closer and found that it was a scratch, as if it had been scratched by something.

Qi Lin immediately took photos and touched the marks on the wall with his hands, trying to find more clues. Unexpectedly, his finger touched a tiny metal particle. He carefully put it into the bag and prepared to send it for testing.

Back in the office, Qi Lin began to sort out the evidence at hand. He turned on his computer and checked various documents and databases, trying to find any information related to the case.

Suddenly, the phone rang. Qi Lin answered the phone and was met by a mysterious voice on the other end.

"Mr. Qi, I know you are investigating the arson case. But you'd better be careful and don't interfere in this case. Otherwise, you will bear the consequences!"

Qi Lin calmly replied: "Thank you for your advice, but I am a professional detective, and my responsibility is to solve the mystery and find the truth. No matter who it is, no one can stop me from fulfilling my duties."

The voice on the other end of the phone was silent for a moment, and then there was a chuckle. "It seems that you are very confident. Well, in that case, then you can continue your investigation. But remember, the flames will burn you to ashes."

Qi Lin was not moved by the threat, he knew this was a key clue. He quickly saved the recording of the call and contacted the laboratory for analysis of metal particles. .
