Office worker Su Jin died suddenly from staying up late, and transmigrated into a book to become Su Nian, the wicked saintess destined to be executed by divine punishment. Starting out burdened with 90 points of evil deeds, she needed to clear them to zero within eighty-one days to stay alive. Abandoning the forced requisition of farmland to build residences, she instead turned to farming and doing good deeds, relying on spiritual plants to reduce evil-deed points, befriending a beast mascot, rescuing the demon clan, city lord, and members of the justice squad, step by step exposing the conspiracy of the heavenly decree book sacrificing saintess every century, and finally uniting everyone to break the shackles of heavenly fate, while unexpectedly unlocking a new journey of the upper realm farming competition.
