Demoted to the Sutra Repository from the Start, I Activate the Sign-In System

Chu Feng transmigrates into a fantasy world, thinking he'll be able to make a name for himself. But just as he gets his bearings, he's demoted to guard the Scripture Pavilion. He plans to keep his head down and stay there until the end of time, but then he unexpectedly activates the Sign-in System. “Sign in at the Scripture Pavilion and receive the Wind and Thunder Art!” “Sign in at the Sword Sect and receive the Peerless Sword Maiden!” “Sign in at the Sea of Death and receive a million undead!” So, uh... anyone still want to compete?
