"You deny that you met Yan Yan in the corridor and said similar words to her?" Bai Tang continued to ask.

"I did meet Yan Yan in the corridor, but I didn't tell her this." The other party still denied.

The audio and video were synchronized to another room through the camera. Yan Yan stared at the face on the computer screen in disbelief.

How can a person lie without changing his face!

"I'm sure she was the one who sent me the message!" Yan Yan was particularly sure.

"Don't be angry, it will hurt you." Cheng Yiming stood behind her, holding her shoulders with his hands.

"Xue Chun, do you believe me?" Yan Yan turned around and asked.

Qi Xuechun stared at the screen intently, "If it's black, it can't be white, and if it's white, it can't be black."

But there were no cameras in the corridor, and the other party denied it. There is really nothing we can do about her at the moment.

Bai Tang could only let her go back first.

Before she left, she said coldly to Bai Tang: "Mr. Police, please don't abuse your rights. I also have the right to complain."

Bai Tang lowered his eyes slightly: "You're good to go."

Cheng Yiming, Yan Yan, Bai Yu, Bai Tang and Qi Xuechun sat down together, it was considered a conversation between friends.

"...When Cheng Haowen was growing up, there were some people who laughed at him. I was responsible for his food and clothing. I asked myself that I had never treated him badly..." Bai Yu said slowly, "There is indeed a relative who is very kind to him.

She also went to find Mr. Cheng and wanted him to help get Cheng Haowen out, but Mr. Cheng refused..."

"Miss Jia told me that her life was ruined by Cheng Haowen. How could she appear here again after being missing for so long..." Yan Yan really couldn't understand, "Since she escaped from Cheng Haowen, she has regained her freedom.

,Why don’t you contact me either..."

"Today's party is organized by the butler, who is one of our own..." Bai Yu hesitated a little when he said this.

At this point, apart from her son and daughter-in-law sitting next to her, and her husband who didn't come to the party, she can still be sure who is hers.

Bai Tang listened to what they said quietly, then stood up and said, "It's very late. You guys should rest first. My colleagues and I will continue to inquire. If I need anything, I'll come back to you."

Cheng Yiming and the others left, and Bai Tang sat back in his chair with his head lowered and said nothing.

"Ms. Zhu is lying." Qi Xuechun said firmly.

Bai Tang slowly raised his head: "Reason?"

"When she answered your question, she quietly looked at the newly installed cameras eight times. When people lie, what makes her most nervous are people and objects she has never seen."

Bai Tang raised his eyebrows: "Do you still understand criminal psychology?"

"Elective courses."

Next time Qi Xuechun says that she has studied industrial chemistry, Bai Tang won't be surprised.

During this period of time, this little girl has shown him her rich knowledge.

He couldn't tell whether Qi Xuechun was an excellent criminal police officer.

But he dared to say that she must be an excellent time management master.

"What are you going to do next?" Bai Tang asked.

Qi Xuechun couldn't believe it: "You let me make a decision?"

"I can give you some detective rights."

Qi Xuechun was happy because her ability was finally recognized, but her joy soon faded.

"You went back on your word and don't want to help me investigate the case?" She said with a serious face.

Bai Tang shrugged: "We must solve the case in front of us first."

She thought that this made sense, and she became happy again, "Next step, I want to follow Ms. Zhu closely."

However, "this requires your support."

Bai Tang sent Qi Xuechun away and continued to question the remaining Cheng family members.

A middle-aged man caught his attention.

"According to the video data, you were very close to Miss Jia at the time. Did you notice anything unusual?" Bai Tang asked.

"No." the man replied.

He was unusually calm.

"Do you remember who else was around at that time?"

He looked at Bai Tang in surprise: "Isn't there surveillance video? Can't you see it more clearly than me?"

Of course Bai Tang knew there was surveillance video, and he wanted to confirm his suspicion. As expected, this man was not generally calm.

He took another look at this person's information, Cheng Ziyou, Cheng Yiming's uncle.

He winked at his assistant and quickly got all the detailed information about this person.

Cheng Ziyou, 46 years old, runs a small company, but the business is not doing well.

He loves gambling and owes a large amount of gambling debt.

"Don't look at me like that." Seeing Bai Tang looking at him, he disapproved and snorted, "Don't you solve cases without evidence? Do you rely on scaring people?"

Bai Tang stood up and came to his side.

He stared intently at Bai Tang. Seeing Bai Tang getting closer and closer, he still tried to remain calm on his face, but his body leaned back involuntarily.

"You...what do you want to do..."

Bai Tang lowered his head suddenly, and Cheng Ziyou almost jumped up, but Bai Tang caught his shoulder in time.

"Mr. Cheng, don't be nervous," Bai Tang smiled slightly, "I'm just doing it as a matter of routine."

Bai Tang returned to his seat and asked the assistant next to him: "Can the evidence be brought in?"

A trace of surprise flashed in the assistant's eyes, then he nodded and went out.

When he came back in, he handed a transparent evidence bag to Bai Tang, "This is exhibit No. 7 found next to the deceased."

A delicate button.

Cheng Ziyou looked shocked when he saw the button clearly.

He immediately looked down at his clothes, and sure enough, there was a button missing from the hem.

There was a big crack in his calm face, and all the panic he had suppressed came out... He subconsciously raised his head and saw Bai Tang coming to him again, his bright eyes staring into the depths of his heart.

"Oh my God!" He couldn't help shouting, falling from the chair to the ground, and all his psychological defenses collapsed.

"I didn't kill him, I didn't kill him..." he yelled in panic.

Bai Tang grabbed his arm and helped him up, "The best way to clear the suspicion is to tell the truth."

"I said……"

Cheng Ziyou gradually calmed down and confessed the truth: "I met her at the door of the villa..."

She dresses like a man, but it doesn't cover up her beauty at all. Sometimes women also like to dress like men. What is called boyfriend style...

In short, if a beautiful woman approaches him, why should he refuse?

She offered to come in with him and be his dancing partner, and he agreed.

However, not long after entering, she disappeared, and his wife arrived shortly afterwards, but he did not dare to look for her.

He didn't even notice when she got close.

Unexpectedly, she was killed and fell at his feet... He was very frightened and was afraid of getting into trouble, so he had been pretending to be calm and wanted to distance himself from the relationship.

"It's really none of my business," he shook his head desperately, "Officer, please investigate and prove my innocence, otherwise my wife will cause trouble at home!"

Bai Tang pursed his lips: "Don't worry, as long as you haven't done it, no one will wrongly accuse you."

Cheng Ziyou went out with a white face.

Bai Tang breathed out, "Call the next one,"

‘He is no longer suspected?’ the assistant wondered.

"He's just a lecher." Bai Tang waved his hand disapprovingly, "Have you found out about the sudden power outage during the party? What are the surveillance videos of each corridor?"

"We found out that the power outage was because the switch tripped," the assistant replied, "but there is no camera at the switch."

The assistant continued: "There are no surveillance cameras in the corridor... It can be seen that the murderer is very familiar with the situation of the Cheng family..."

Before he finished speaking, Bai Tang had already stood up and walked out.

The assistant couldn't help but scratch his head. When the clues were of no value, Bai Tang was too lazy to listen to them all.

But what he just said has no value at all?

Bai Tang first walked through the corridor leading to the electric switch and stopped at the electric switch.

This is the corner at the end of the corridor, with a floor-to-ceiling window on the side.

Bai Tang stood in front of the electric switch and closed his eyes quietly... He imagined that he was the one who pulled the electric switch. The moment all the lights went out, a black figure appeared in the living room and brutally killed Miss Jia.
To be continued...
