This is a piece of paper.

What paper?

Old manuscript paper with mottled blood.

There is content on it, signature on it, and it also clearly indicates the recipient.

This is a letter, a bloody letter, a letter printed with blood drops and blood fingerprints.

What else?

What else can you see?

Lin Yue held the blood letter carefully wrapped in a transparent bag of evidence, his eyes were as cold as a pond, and he focused on being divine.

Of course he can see a lot more.

"There are dripping blood on the paper and obvious burr-like protrusions on the edges."

This shows that the height of blood dripping is more than 50cm away from the paper surface.

"And the lower end of the dripping blood stain is also derived from the columnar blood stain."

This shows that for a short time after blood drips on the paper, the paper is not always completely laid on the plane. Instead, it is in an inclined state with slope and height drops.

"The flow columnar blood stain is connected with metastatic blood stains, and the blood stains and handwriting are highly integrated."

"It is obvious that the active object of blood stain is the nib of the writer."

This shows that the moment when blood is dripping is almost the moment when letters are written.

Only when the writer's pen tip touches the blood drop will he write "blood words".

The blood dripping height of more than 50cm, the paper space state when the blood drips, and the "blood words" formed by the fusion of handwriting and blood stains, if this information is integrated...

What can be restored?

Lin Yue seemed to be about to "see" the picture.

But a messy footsteps disrupted his interruption.

"Senior brother, the DNA appraisal report you want."

"Brother Lin, the fingerprint comparison results you want."

Two people appeared at the door of the office at the same time.

One woman and one man, all holding freshly baked documents in their hands.

"Please trouble you guys."

Lin Yue stood up to greet him and nodded in thanks:

"Shiyu."

"Wenjun."

The Third Squadron of the Criminal Police Brigade of Weilan City Public Security Bureau, Forensic Medical Office of the Technical Squadron, Ye Shiyu.

The Third Squadron of the Criminal Police Brigade of Weilan Municipal Public Security Bureau, the Trace Office of the Technical Squadron, Xu Wenjun.

They are not only Lin Yue’s colleagues, but also Lin Yue’s:

College junior sister, current girlfriend.

Junior high school classmate, little brother.

Because of this unusual relationship, Lin Yue privately asked some "work" to him.

"Senior brother, the DNA comparison result of the two blood samples you gave me is..."

"Brother Lin, the result of the comparison of the two fingerprint samples you gave me is..."

Ye Shiyu and Xu Wenjun handed over an appraisal report at the same time.

These are two identification reports with different projects and different contents. One compares the 20 loci of two blood samples and the other compares the 13 characteristic points of two fingerprint samples.

The comparison results of these 20 loci and 13 characteristic points are:

"Identity comparison is consistent."

“Consistent…”

Lin Yue's pupils shrank.

“Really consistent?!”

He couldn't believe his eyes.

But the identification report will not go wrong, and science will not go wrong.

Even if there is an error, it is impossible for two reports to go wrong together.

"Hey, what a joke..."

"This is unscientific!"

Lin Yue suddenly muttered to himself, his tone as if he was questioning the world.

This made his girlfriend and brother care more:

"Senior brother, what's wrong with you?"

"Where did the two blood samples you gave me come from?"

Ye Shiyu frowned slightly and asked questions with concern.

Xu Wenjun was also worried and asked repeatedly: "Yes, Brother Lin, the two fingerprint samples you gave me, especially the blood fingerprint samples... where did the sample come from?"

"Why don't you report the situation to the organization and ask us to do an appraisal and comparison in private?"

"..." Lin Yue was speechless.

He was silent for a long time before finally giving an answer that he couldn't believe:

"The owners of these two fingerprint samples and blood samples are both me-"

"It's just that one of them was taken by me today."

"And another blood and fingerprint come from..."

"I'm in the future."

As he said that, Lin Yue slowly revealed the blood letter.

This is a letter, a letter from the future.

"This morning, someone put this letter in my car."

There are only a few words written on the letter:

"Don't change the past!"

"The watch is the key!"

"——You in the future, Lin Yue."
