After a Century of Sign-Ins in the Imperial Palace, I Can No Longer Hide My Expert Identity!

After transmigrating to a high-martial world, Qin Mu became a low-ranking official tasked with guarding the library.

Demons ran rampant in this world, and the demonic path flourished. The mighty could kill from a thousand miles away and cleave mountain ranges with a single sword stroke.

He thought his life would pass by uneventfully, until he suddenly awakened a sign-in System.

"Congratulations on signing in at the library. You receive the reward: Dao-level calligraphy."

"Congratulations on signing in at the princess's residence. You receive the reward: Heavenly Flying Immortal."

"Congratulations on signing in at the Golden Throne Hall. You receive the reward: Words Become Law."

One day, a piece of calligraphy Qin Mu casually wrote helped the ninth princess of the Great Zhou Dynasty break through to the Grandmaster realm.

Another day, a painting Qin Mu casually made drove an entire sect into a frenzy.

A hundred years later, when the Demon Lord led the demonic sects in an assault on the imperial palace, Qin Mu casually uttered a single sentence, and the entire demonic sect was wiped out.

He knew that he might no longer be able to hide his identity as a "master."
