"What's going on here?" Zhang Zheng thought he had made some new discoveries, so he hurriedly strode forward, but after looking at it for a long time, he didn't see anything strange, "There is no abnormality?" Except for being a little dirty. ”

There was a little muddy water on the windowsill, probably because the rain had left a mark on the dust on the windowsill.

"Don't you think it's strange? There is no mud anywhere else, why is it only here? ”

Zhang Zheng scratched the back of his head and thought seriously for a moment, "Maybe it's ...... Particularly dirty here? ”

"No!" Bai Jingyu's eyes narrowed for a moment, and his tone was firm, "There have been two people here, it may be a gang." ”

When he entered, he noticed some mud stains on the ground, and he didn't think about it at the time, after all, there were several people standing here.

But now that I think about it, I feel very suspicious, because the dean and the nurse have been in the office all the time, and there is no mud on the way from the office. And the old king next door was wearing slippers on his feet, and it was impossible for him to leave them.

Then the only possibility is that the mud stain on the window was left by another person.

"Huh?" Zhang Zheng was still a little confused about his reasoning, "An old lady who is almost eighty years old can fall to the ground with a casual push, is it worth committing a gang crime?" What is the motivation? Seeking wealth? Who will come to the nursing home to rob? Oh yes, I just asked the dean, and it is said that someone came to the nursing home yesterday to inquire about Wang Cuihua. ”

"What are they inquiring about?"

Zhang Zheng touched his chin and sighed, "That little nurse didn't say it clearly, but it just said that someone seemed to have come to Wang Cuihua to inquire about what car accident happened five years ago." ”

Bai Jingyu's eyes narrowed heavily, "The car accident explosion five years ago? ”

"Yes, yes! It's an explosion car accident! The little nurse said that when she came to measure Wang Cuihua's blood pressure this morning, she chatted casually with the nurse. ”

"What else did they talk about?"

Wang Cuihua said she saw with her own eyes that five years ago, the students in the car lit their own lighters, and then the car exploded. However, the nurse said that Wang Cuihua's words were not credible, she had not been in a good mental state in the past few years, and she often forgot what she said a second ago, so how could she remember what happened five years ago? ”

Bai Jingyu didn't answer and fell into deep thought.

If Wang Cuihua was really a witness to the car accident five years ago, then he also had a suspicion in his heart about who killed her.

Thinking of this, he suddenly turned and strode out the door.

'Boom-'

As soon as he left, another thunderclap sounded outside the window.

The moment the lightning struck, the dimly lit room was much brighter, and the faint blue smoothed over the face of the deceased.

Zhang Zheng was trembling, and hurriedly chased after him at the useless door, "Jingyu, where are you going?" Wait for me! ”

Bai Jingyu stood at the end of the corridor, took out his mobile phone and dialed it and put it to his ear, his eyes staring at the rain curtain with heavy eyes.

"Hello?"

When a question sounded in his ears, he frowned and asked unceremoniously, "Did you send someone to kill Wang Cuihua?" ”

"What flowers?" On the other end of the phone, Gong Ming felt inexplicable, "You called me to wake me up at night just to ask about such a boring thing?" ”

"A human life, you are bored?"

"In this world, someone dies every second, do you have to ask me if someone dies? Don't you like to tell the truth? Now that you can't find the murderer, you're going to put this hat on my head? ”

"It's really not you?"

"Neurotic!" Gong Ming scolded, ignored him, and hung up the phone directly.

Bai Jingyu listened to the busy sound of 'doodoo' on his mobile phone, and the uneasiness in his heart became even stronger.

If it's not Gong Ming, then who else is investigating the bombing five years ago?

L？

However, despite L's bad deeds, he has never harmed a single person.

There is no reason for such a person to kill an old man who is so old that he can't even move.
