Siheyuan: After Ten Years of Sign-Ins, I Emerge Invincible

[Siheyuan] + [invincible sign-ins] + [behind-the-scenes mastermind] + [steamrolling everyone] + [ten years of honing his skills] He Yutie transmigrates, but doesn’t return to the Siheyuan right away. Instead, he’s stranded at a frontier outpost for ten years! Luckily, he activates the Frontier Sign-in System. Every daily sign-in earns him a reward! “Sign in at the border marker and receive [Grandmaster-level Baji Fist]!” “Sign in at the armory and receive [God-level Firearms Mastery]!” “Sign in at the mess hall and receive [ten thousand jin of rice]!” Ten years later, He Yutie leaves the army with a warehouse full of supplies and extraordinary skills! Back in the Siheyuan, now crawling with scoundrels, he sees his younger siblings being bullied and smiles. Ten years of ice can’t cool a hot-blooded heart. Do you really think I need to reason with a bunch of nobodies like you? Silly Zhu gets set up? He turns around and makes him head of the cafeteria! Yushui is insulted? He gets her into the best university! The Jia family dares to cause trouble? He leaves them with nothing overnight! The scoundrels in the courtyard tremble: We’re still playing in the dirt, and he’s already piloting a Gundam?
