"Qin Yushen, you said there was progress?"

"Huh?" Qin Yushen was shocked to realize that he was distracted, "Yes, we found the security guard of the building where your mother died. ”

He clearly saw that Ye Zhixing clenched his fingers, her complexion turned from white to blue, and she was forbearing.

In the team, he is used to painting portraits of various people, grasping characteristics, and letting him instinctively analyze each other.

Ye Zhixing actually couldn't wait to meet and interrogate the security guard in person.

But she knew that it was inconvenient for her to show up, and it was easy to startle the snake.

Professionals do professional things, she handed it over to Qin Yushen, and she believed him.

Probably because he always spoke very similar to the person who saved her, which made her trust in the dark.

"Huh? So what did he say? ”

"There were no cameras in the dilapidated building back then, only this security guard, and he didn't remember what happened back then for so many years, but fortunately, there was a registration book back then, and the entry and exit lists were all recorded."

Ye Zhixing's eyes were shining, and he watched Qin Yushen push the book over.

She was looking intently at the register, and he was looking at her intently.

She was really good-looking, the most beautiful woman he had seen in all these years, and before that, the most beautiful was his mother.

He didn't know if he was thrilled by how he felt about her, but he was a workaholic, and his instincts told him that her abilities would help him progress in his work and help more people.

Therefore, in public and private, he hopes that she will work with him.

Now to put it bluntly, it will definitely scare her, and misunderstand him, thinking that he is using her.

Qin Yushen's brows furrowed for a while, then loosened for a while, and went over and over again.

He had always been a resolute man, but he was hesitant about it.

"So, is there any handwriting on this one that you suspect is there?"

"Nope."

Ye Zhixing closed her eyes, which was also expected, Yang Zhi may not be able to do it herself, she may be a bad person, she doesn't want her hands to be stained with a little blood, her more common method is to kill people with a knife.

Therefore, the truth that Ni Sishang said before she died may not be 100% correct.

But...... She hated her mother so much, of course she hoped that her mother would be desperate before she died, and the last person she saw was her.

In this regard, she is still the most likely person to push her mother downstairs.

It's just that...... Yang Zhi is very cautious in doing things.

"Then I'll take it to the handwriting library and compare it."

"Thank you. Superintendent Qin. ”

Qin Yu's eyes darkened, he still preferred to hear her call him by his name, he folded his hands, "But you have to be mentally prepared, even if the handwriting is right, it doesn't mean anything, it's just that we have narrowed the scope of suspicion, but it is not strong evidence." ”

"I know."

Ye Zhixing had been mentally prepared for a long time.

Looking at what happened so many years ago, it's normal for progress to be slow.

Qin Yushen was able to find the security guard of the year in such a short time, and he already took this matter very seriously.

She is not in a hurry for quick success, she is willing to hide in the dark like a hungry wolf, wait for the opportunity, and then hit with one blow!

After chatting about business, Ye Zhixing's coffee was finished, "I still have class, I'll go first." ”

Qin Yushen also stood up immediately, and said without allowing her to refuse, "I'll send you." ”

Ye Zhixing nodded, this is a very gentlemanly behavior, if she vetoes it, on the contrary, it is a bit like crossing the river and demolishing the bridge.
