Night Zhou State historian Shen Yezhou accidentally steps into the Heaven Evolution Machine that holds the destiny of all living beings, getting tangled in a fate chart upheaval spanning three realms. Those who guard order follow the rules, every step paying a price; those who hold balance mediate in all directions, only seeking to keep the warmth; those who forge ahead recklessly burn themselves to the ground without regret. All three forward paths are fraught with danger, and only Shen Yezhou, who refuses to sign off on a dead end, uses a blank page to reversely break the rules and judgments. Heaven and earth are impermanent, all fates evolve; the so-called deduction has never been a scripted play.
