Villain: Without Morality, You Will Not Be Kidnapped!

Qi Lin frowned, he could feel the complexity of this case. He put down the file and began to walk back and forth in the room, the details of the case echoing in his mind.

"We need to find more clues, Xiao Yang. This case requires us to investigate more deeply." Qi Lin said.

"But, we have been investigating for a few days now, where do we still need to find clues?" Xiao Yang said helplessly.

Qi Lin looked out the window, his eyes deep and firm, "I believe our goal is clear, now we need to find more clues to solve this mystery.

The next morning, Qi Lin and Xiao Yang started a new investigation. They found Lin Yu's family and friends and asked them one by one about Lin Yu's activities and contacts during his lifetime. Qi Lin's eyes are sharp. He pays attention to every detail, constantly asks questions and guides the conversation.

"Did you notice any unusual behavior or emotions in Lin Yu's life?" Qi Lin asked Lin Yu's family.

"No, she has always been a very cheerful person, but in life," Lin Yu's sister hesitated.

"She seems to be a little worried recently, but she didn't tell us." Lin Yu's mother added.

Qi Lin nodded, "Have you noticed who she has had conflicts or conflicts with?"

"It seems not, she has always been a very gentle person." Lin Yu's family members shook their heads.

Qi Lin asked some more questions and then left Lin Yu's home. He and his assistant came to where Lin Yu worked and talked with her colleagues.

"Lin Yu is an excellent employee. She works hard and treats people warmly," said a colleague.

"Has she ever had any conflicts or conflicts with anyone?" Qi Lin asked.

"We don't know much about this, but I know she had an argument with a client recently." Another colleague said.

Qi Lin left the customer's name and contact information, and then left the company. He and his assistant returned to the detective station and began to analyze the information collected.

"It seems that Lin Yu is a very ordinary person, but there must be some secrets in her." Qi Lin said thoughtfully.

"We need to find more clues." Xiao Yang agreed.

They began to study the information of the customer who had quarreled with Lin Yu. The customer's name is Zhang Wei, and he is the owner of a company. Qi Lin and Xiao Yang came to Zhang Wei's company and questioned his employees.

"Has Zhang Wei had any quarrel with Lin Yu recently?" Qi Lin asked Pang.

"Yes, they had a quarrel." But we don't know the specific reason. "An employee replied.

Qi Lin nodded, left Zhang Wei's contact information, and left the company. He and his assistant returned to the detective station and began to analyze the information collected.

"This Zhang Wei must be related to Lin Yu's death." Qi Lin said.

"We need to find more evidence." Xiao Yang agreed.

Qi Lin looked at the night outside the window, his eyes firm and sharp. "I'll find the evidence," he said.

In the next few days, Qi Lin and Xiao Yang conducted an in-depth investigation of Zhang Wei. They found that Zhang Wei was a person with severe mood swings and often had quarrels with employees. He has also been sued several times for alleged fraud and unfair competition. Qi Lin collected this information and then decided to have a face-to-face conversation with Zhang Wei.

"You are the last person to see Lin Yu alive." Qi Lin stared at Zhang Wei and said. .
