After young criminal investigation consultant Lu Yi used his extraordinary insight to solve a seemingly perfect secret room murder case, a pure black card of unknown material appeared on his desk.

23:59:57.
Twenty-four hours.
What happens when the countdown ends?
The twenty-four-hour countdown has begun. But Lu Yi didn't know that his peaceful life had been completely broken from this moment on. A road leading to the unknown and the abyss was unfolding silently at his feet.
