Transmigrated to Mr. Zombie: My System's Unhinged

One moment, Tan Wenjie was immersed in a zombie-hunting mobile game; the next, he's a pampered millionaire's nephew in 1912 China, accused of demonic possession. His uncle forces him into a bizarre fertility test via a magical laxative, then an arranged marriage to a powerful Marshal's sister-in-law, all while townsfolk eye him as a lecherous scoundrel. Luckily, his LitRPG system transmigrated with him! The catch? It's utterly unhinged. To level up, he must hunt the unliving. To learn cultivation, he has to bribe a greedy Taoist master who actively tries to hinder his progress. And his new \"talents\" include \"Ragged Clothes\" (no money overnight!) and a baffling \"L1\" (0% fertility). Can he exploit this bizarre system and outwit his conniving mentor, or will this strange path to power lead only to his bizarre undoing?
