The two gunshots in the cemetery in the rain were thunderous and shattered. Retired special forces hacker Lu Zheng returns to his senior year of high school with his childhood sweetheart Su Wan. The warmth of the broken jade has not dissipated, and the nightmare of the tragic death of the brothers is still there - the tombstone of Interpol Chen Mo, the vegetative money tycoon Lin Shen, and the missing speedster gang boss Zhao Ye, all point to the sinister Jiang Chichuan.
But in the mismatch of time and space, the young Jiang Chichuan is still a timid student, but the adult Jiang Chichuan has traveled through time with hatred, hiding in the dark and setting up traps: high-voltage electric traps, laboratory explosions, fire cages, and they are closing in step by step. Lu Zheng used his flesh and blood to clear the way, carrying people in the fire to defeat his inner demons, but he was shocked to realize that the hesitation of young Jiang Chichuan might be a foreshadowing of future tragedy.
In addition, Chen Jianlu, a transfer student, came with secrets from his old school; Should he rewrite his fate to protect his loved one, or make the same mistakes again? Broken jade is still the same year, every step is a gamble of life and death.
