Villain: Without Morality, You Will Not Be Kidnapped!

Li Jing nodded, looking more relaxed. "Okay, if I have any more ideas, I'll let you know.

Based on the clues provided by Li Jing, Qi Lin launched an investigation into Zhang Tao. He discovered that Zhang Tao was quite famous in the jewelry collection circle, but there were also some negative rumors related to him. This made Qi Lin more certain of his suspicion.

Qi Lin decided to make an appointment with Zhang Tao to learn more about the situation. "Hello, Mr. Zhang. I am Detective Qi Lin." He walked into a cafe and found where Zhang Tao was sitting.

Zhang Tao raised his head and glanced at Qi Lin, showing a trace of displeasure. What's the matter? Why are you looking for me?"

Qi Lin smiled and sat down. "I am very interested in jewelry theft cases. I heard that you are a jewelry collector and I would like to ask you to share some professional knowledge.

Zhang Tao's expression softened slightly. "Oh, that's it. Do you want to know the value of jewelry and how to identify it?"

Qi Lin nodded. "Yes, could you please give me some guidance?"

So Zhang Tao began to introduce the types, quality and evaluation standards of jewelry to Qi Lin in detail. During the conversation, Qi Lin cleverly guided the topic and asked Zhang Tao some questions related to the theft case.

"Mr. Zhang, have you heard about the recent jewelry store theft?"

Zhang Tao frowned. "Theft? Really? I've never heard of it."

Qi Lin deliberately slowed down his speech. "As far as I understand, this case may involve some high-value gemstones. As a jewelry collector, this should be of interest to you."

Zhang Tao was silent for a moment, and then sighed. "Well, I did hear some rumors. Some people said that a batch of rare sapphires will soon flow into the market, but I can't confirm the specific details." Zhang Tao said slightly hesitantly.

Qi Lin stared at Zhang Tao's eyes and noticed his uncertainty. "Mr. Zhang, I must remind you that if you conceal any information related to the theft, it will have serious consequences for you. As a detective, my duty is to restore the truth."

Zhang Tao lowered his head and thought for a while, then raised his head with a firm expression. "Okay, I admit I heard the rumor. But I was not involved in any thefts and had no contact with the stolen jewelry."

Qi Lin nodded, expressing understanding. "Thank you for your confession. It would be very beneficial if you could provide more information to help us find the real criminal."

Zhang Tao sighed. "To tell you the truth, I did come into contact with the transaction of some precious gems a few months ago, but I didn't know the source of these gems." I am just a collector and don't know much about the dark transactions in the jewelry market. "

Qi Lin recorded this information. "Thank you very much for your cooperation, Mr. Zhang. I will continue to investigate and hope to find the truth as soon as possible."

Qi Lin returned to the office and began to sort out all the clues. He found one thing in common: the descriptions provided by Li Jing, Zhang Tao and witnesses were all related to a person named Ma Zhiyuan.

Qi Lin decided to interview one of the witnesses and ask him for more details. "Mr. Wang, can you describe again the two strangers you saw at that time?"

Mr. Wang closed his eyes and recalled for a moment. "One of them has a beard, wearing a black coat and a hat. The other has short hair, wears glasses, and looks very elegant.
