Shen Xiao chuckled, looked at the dazzling girl in front of him with great interest, but her eyes were full of indifference and coldness, and explained to Lu Wen unhurriedly:

"Standing on the rooftop, the direction of the blood characters is correct, which means that it cannot be written by someone standing on the rooftop, but by someone standing in the air, parallel to the wall, so that such words can be written."

Lu Wen heard half of it, and his eyes were already full of suspicion:

"How can a man stand in mid-air?"

Jiang Bai walked to the edge of the rooftop at some point, squatted down on one knee, and motioned for the two to come over.

Lu Wen looked in the direction of Jiang Bai's finger and understood.

There is a row of protrusions under the wall outside the rooftop, which is difficult to stabilize but can still be used for a short pause.

If you grasp the edge of the roof with one hand and step on the bulge with the other foot, you can write those three blood characters, and the distance is also suitable.

However......

If Li Pingping was pushed down, the murderer would not kill them all, nor would he help, what did he want to do?

Lu Wen thought so and asked so.

A dark glint crossed Jiang Bai's eyes, and he pondered for a moment and said:

"Lacking key evidence, I only have a rough guess at the moment."

So Lu Wen turned his gaze to Shen Xiao again, Shen Xiao smiled innocently, and confessed:

"I don't know."

Lu Wen knew the urine nature of the person in front of him, and threatened in a cold voice:

"Shen Xiao, believe it or not, I'm shouting here, your fans can trap you here?"

Shen Xiao smiled, raised his eyebrows and looked at Lu Wen, sighed faintly, and said:

"Cub, why does Dad have a stupid son like you, the handwriting identification confirmed that the blood words were left by Li Pingping, if she wanted to ask for help, why didn't she make a sound, but tried her best to keep it from falling, and she had to write the blood words far away?"

Lu Wen groaned slightly, slapped his hand violently and said:

"Because Li Pingping couldn't make a sound at that time!"

At this time, Jiang Bai's voice also interjected:

"Li Pingping's cold has worsened since yesterday, and her voice is so hoarse that she can't speak, which is completely in line with the situation at the scene."

Therefore, the deceased left blood just to ask for help.

Lu Wen frowned, and didn't bother to ask Jiang Bai where he knew the information for a while, and speculated:

"Could it be that Li Pingping accidentally fell off the rooftop, stabilized her body with the help of the wall bulge, and called for help with blood words but no one found out?"

Lu Wen felt that he had discovered the truth.

However, this illusion only lasted for a second.

I only heard Jiang Bai clearly organized, and said in an extremely calm tone:

"No way. First of all, the railing of the rooftop is not low, and ordinary people cannot fall unintentionally no matter how much they toss. ”

Lu Wen thought about it and said without giving up:

"What if Li Pingping wants to commit suicide and regrets it the moment she turns it over?"

Jiang Bai narrowed his eyes, a chuckle suddenly appeared at the corner of his mouth, and he said in a low voice:

"Then I'm going to ask Li Pingping's classmate......"

-

Twenty minutes later, the principal of the school hurried over.

Lu Wen found a vacant classroom and temporarily used it as an interrogation room.

While waiting for someone, Shen Xiao stared at Jiang Bai like a torch, but the latter turned a deaf ear.

Lu Wen couldn't help but complain to Shen Xiao:

"Xiao'er, when this suicide case was transferred to me, I thought that I couldn't stand it anymore when I saw me so idle, but who would have thought that a suicide would run into you and turn into murder, you are really ......"

Possess the Grim Reaper.
