Jiang Xu was born to be able to see the "folds" under the surface of the world - the too heavy shadows in the sun, the echoes in the footsteps that should not exist. He called it a "miracle" and used his profiling instinct to record everything.
The appearance of transfer student Jiuchi broke the balance. In Jiang Xu's empathy perception, he is an absolute "perception black hole".
Immediately afterwards, three lines of bloody seven-day rules appeared in front of Jiang Xu's eyes.
Now, he must use his best profiling to dissect this inhuman thing that is devouring him.
The countdown has begun.
Intention: Use logic to measure the world, use empathy to understand each other, until you encounter a completely "unsolvable" existence.
