Uncle Nine: I Sold Myself to a Jiangshi and Awakened the Corpse-Commanding System

Reincarnated as Ren Qianqian, who was sold to a zombie bride for thirty million by her stepsister, I wake up in a coffin, wrapped in a wedding dress and surrounded by the stench of decay. Sister Susu is waiting outside to collect the money, so I pound on the coffin lid with all my might. Crack! A fissure appears! The System chimes, announcing that loading is complete: the Corpse-Controlling System is activated! Reward: Zombie-Affinity Physique!
