Wang Zi, a transmigrator, has a system: "The stronger my wife, the stronger I get!" While others train hard to become stronger, all he needs to do is marry! Level up effortlessly! ...The story begins with his genius and beautiful fiancée, Murong Bing, wanting to break off their engagement. Wang Zi makes a bet with her: she marries him, and if she ever defeats him in battle, he'll set her free. Later... Murong Bing: No!!! Why do I train so hard, while Wang Zi sleeps till noon, enjoys himself, and I still can't beat him? My husband is too demonic! Wang Zi smiles like a capitalist: Hehe, you're just a worker in my upgrade factory.
