For Jiang Bai, according to Liu Han's current situation, there are actually early signs.

But when Liu Han was really suspected, it was only a few minutes before Principal Zhang's crime was exposed.

In order to find the method of throwing the corpse, Jiang Bai did not pay attention to other people's bodies at first.

However, after figuring out the modus operandi and finding the corresponding clues and evidence, Jiang Bai found one of the most important problems when he conducted a comprehensive review of the case.

"If Principal Zhang is the real murderer, then why did he leave a clue?"

With the blessing of the "Palace of Thinking" ability, Jiang Bai's mathematics and theory of the case surpass all the people in the case.

Even if Principal Zhang was able to hide Jiang Bai, the reason was that the clues were not enough to deduce the real murderer.

But since everything has been smoothed out, what Principal Zhang did, as well as his abnormal performance, are enough to show that he is not the real murderer, and Jiang Bai can naturally feel the abnormality at this point.

In the limited clues, it is not obvious, but it is logical to find the problem.

In that case fifteen years ago, if Principal Zhang was the murderer, then there have not been a few cases in the past fifteen years.

This in disguise means that Principal Zhang can restrain his illness to a certain extent.

Just like the scars on his arms, if these scars are to solve the pain of the manic attack, then what is the reason for the case to happen fifteen years later, and why did Principal Zhang add a few new scars to his arm.

This is a rather contradictory point.

And it is worth mentioning that if Principal Zhang is the murderer, then why would he be so perfunctory about his related majors when Jiang Bai questioned him?

He even deliberately lied that he didn't know anything about mania.

This is almost deliberately directing all the questioning eyes to himself.

Although I didn't think it was strange at the time, after knowing the modus operandi, these simple things became the problem.

However!

A large part of Principal Zhang's behavior is that he is subconsciously protecting another person.

And Jiang Bai learned very early that the previous old principal was called Liu Qingchuan, and he was an old Chinese medicine doctor who was still a little famous.

Combined with the above characteristics of the murderer and the harm to the victim, and the victim did not engage in any confrontation, and remained conscious.

This point became Jiang Bai's breakthrough.

And Liu Han's exposure will be logical and go further.

There is also the sophomore boy at the University of Political Science and Law who is almost Chu Yin.

Is that a crossbow, the same one that transports corpses?

Jiang Bai didn't know, so it could be said that he didn't want to know either.

All this has nothing to do with him for the time being.

At this time!

He had boarded the train.

Jiang Bai knew very well that Guan Hongshan and they would soon discover their existence next!

Then the last ten days of the next ten days are the time to really decide!

……

On the other side, Liu Han is being interrogated by the Jingbei City Bureau.

The staff is routinely taking notes.

She sat in the interrogation room in a daze, without any expression on her face, answering Guan Hongshan's question.

"Yes!"

"People, I killed them!"

"That's right, it has nothing to do with Principal Zhang."

Liu Han confessed to what he had done.

Her eyes were dull, staring at the table like a pool of stagnant water, and no change was seen on her face.

Liu Han explained the process of committing the crime very quickly, and there was nothing to hide, which meant that Liu Han had pleaded guilty to the current situation.

However, every word that came out of her mouth made the staff present feel extremely shocked!

Guan Hongshan, looking at Liu Han in front of him, couldn't help but feel incredible after hearing her modus operandi!

"That's how it was"

"But how did Jiang Bai guess?"

"If Liu Han doesn't explain himself, who will guess in that direction?"

And at the moment!

Although Liu Han was being interrogated, Lu Hai's heart was full of a lot of thoughts.

According to what Liu Han said, when she was in the seizure period, she could bear it at first, but the later she went, the more she couldn't control it.

But she can't do anything to other people, all she can do is vent as much as she can.

And this kind of time when you can't really vent will also accumulate later.

And for that outbreak, she will do a good job of foreshadowing.

Guan Hongshan, his cold gaze fell on Liu Han's face.

"When did your Uncle Zhang start assisting you in committing crimes?"

Liu Han answered Guan Hongshan's question without concealment.

"Probably, you helped me in the beginning."

"He should know what happened to me."

"But Uncle Zhang feels very sorry for me."

"I didn't have a father when I was very young, and Uncle Zhang is no different from my biological father in my eyes."

Liu Han's words sounded very cold, but in his words, you could feel the deep relationship between him and Principal Zhang.

"So many years have passed."

"I didn't expect that when my grandfather died, what he once said turned out to be what it meant."

"Grandpa asked Uncle Zhang to take care of me at that time, and then said again, if you have the same problem, then choose to call the police directly."

"But now I know."

"The cause of my father's death is probably because of this!"

At this time, Guan Hongshan couldn't help but feel sad when he heard Liu Han's experience.

In this hereditary mental illness, it will inevitably cause great trauma and shadow to the child's body and mind.

And why no one has ever discovered the dangers of this disease before.

However, at this time, Guan Hongshan knew that his responsibility was not in this.

He flipped through the file for a moment, then continued his interrogation.

"The situation you explained before, that is, when the onset of the disease, there is a cycle, right?"

"But as far as we know, that's not the case."

How do you explain this? Do you have a tendency to hurt people? ”

"The previous cycle of onset was about half a month, five days, or even seven days."

"But there was one time in between, and there was only a three-day gap between the two cases."

"And this irregular criminal motive has had a great impact on Chu Yin and Qin Ming's judgment."

Hearing this, Liu Han raised the corners of her mouth slightly, and she, who had been expressionless, actually smiled at this moment.

"At that time, it was the menstrual period."

"Leads to less emotional instability,"

"Shut down the team."

"You don't need me to elaborate on this kind of thing, do you?"

As soon as these words came out, they exploded in everyone's hearts!

Guan Hongshan didn't make a sound, but paused slightly, then looked at the colleague next to him, and then didn't say anything.

And Liu Han's answer was indeed beyond everyone's expectations.

How could it be?!
