Ling Heng, a second-year high school student, dug out a dilapidated ancient book "The Records of the Ling Family" in the attic of his hometown.
By turning the pages of the book, you can step into a hidden time gap, like a special passage invisible outside reality.
He will incarnate as the ancestors of the Ling family and experience the wars of the late Sui Dynasty, the old events of the Song and Ming Dynasties, and even modern times.
The iron rule of the crack: you can only witness the past and never tamper with history that has already happened.
The residual artifacts brought back from the cracks have special powers, but the price is heavy: those who rely on them to do evil will be corroded by the obsession of the times and used for profit, and the corresponding chapter will be permanently annihilated.
And the peepers who coveted this ancient book had quietly set their sights on him.
