I Became a Saint After Ten Years of Sign-Ins

Luo Wushuang transmigrates to a fantasy world with an abysmal talent, leaving him no choice but to become an odd-job disciple in a minor sect. He thinks he will spend the rest of his life in obscurity, but unexpectedly, he binds himself to a sign-in System. “Ding~ Congratulations, Host, your sign-in was successful. Reward: Chaos Void Sword Body!” “Ding~ Congratulations, Host, your sign-in was successful. Reward: Heavenly-ranked weapon, Purple Sky Sword!” … From then on, Luo Wushuang keeps a low profile in the sect, signing in and cultivating every day. Years later, demons descend, and when no one among humanity can stand against them, a streak of sword light cleaves through the sky, stunning the entire world!
