The Seventh Personality

Third notice

March 15, 2024, 8:30 p.m.

In the monitoring room of Xinhai Medical Center, Chen Mingyuan stared at the real-time picture of room 404. Dai Jianguo was sorting out the documents in the safe when, suddenly, he seemed to perceive something and suddenly turned around.

But there was no one behind him.

"Captain, look at this!" Xiao Li pointed to another screen. "Video from ten minutes ago."

A doctor wearing a mask wheeled a medicine cart into the spare elevator in Room 404. There was a portable medical kit in the car, the same model as the one at the scene of Zhang Ting's murder.

"Can you see his badge?"

"Wait..." The technician zoomed in, "Yes... Dai Xiangyang!"

Chen Mingyuan's mobile phone suddenly rang:

"You got it. I am Dai Xiangyang.

Seven years ago, they turned me into a perfect test subject.

Now, it's time for me to give my father a taste of therapy.

Room 404. See you in two hours.

- The scavenger."

'No! Gu Yuwen looked at Dai Xiangyang's medical records, "You look at these medication records..."

Among the many drug names in the medical records, one prominent diagnosis stands out:

"Split personality, severe delusions. Preliminary diagnosis: dual identity disorder.

Signature of attending physician: Kevin Zhang.

Just then, another text message arrived:

"Don't let him fool you.

The real Dai Xiangyang is long dead.

The truth in 404 tonight will surprise everyone.

- Another scavenger."

The door of the monitoring room was suddenly pushed open and a nurse rushed in: "The spare elevator in room 404 just found this!"

It was an old diary, and the flyleaf said, "Dai Xiangyang's Treatment Diary, by Kevin Zhang."

【 March 15, 2017 】

Take over Dai Xiangyang's treatment today. The child's case was unique, and his father requested a "personality reconstruction." But this technology is still in the experimental stage, and the risk is too high...

[March 16, 2017]

There was an accident with the treatment. After the injection, Dai Xiangyang's personality was split. He started calling himself "Kevin Chang's brother." Is it...

[March 17, 2017]

It's all over. Dai Xiangyang died during treatment. But Dai Jianguo insisted on continuing the Sequoia Project, and my sister became the next experimental subject. Father tried to find out the truth, but...

Half of the last page was torn away, and only a few scarlet letters remained:

"We are all victims and we are all murderers."

Before Chen Mingyuan had time to think, the intercom sounded: "Team leader! Theft from the archives! All of Dai Xiangyang's original medical records are gone!"

Suddenly, the hospital public address came on, and it was a processed voice:

"Officers,

Want to know who Dai Xiangyang really is?

Meet me in room 404 in two hours.

Remember, everyone wears a mask.

But tonight, all the masks will be torn off.

PS: Captain Chen, is your daughter still in the children's ward?"

Chen Mingyuan's heart suddenly sank. His daughter was hospitalized in this hospital after a car accident, treated by... Kevin Zhang.

On the surveillance screen, the lights in room 404 suddenly went out. When the emergency light came on, there was a body in the middle of the room, covered in a white cloth.

On the white cloth, written in red liquid:

"Third doll, ready.

For those who want to pry.

I'll see you at 10:30 tonight.

-- Dai Xiangyang/Zhang Kaiwen/Scavenger"

Gu Yuwen's voice trembled a little: "Group leader, did you find it? These three signatures... It's a different handwriting."
