Having studied for a hundred years, why do you call me the Martial Saint?

Transmigrating into the body of a menial disciple of the Suishan Sword Sect, Gu Shuxian unexpectedly awakened the Langhuan Guardian Contract. Upon closer inspection, he realized it was essentially a librarian's job! Was he destined to become the sweeper of the scripture pavilion? As long as Gu Shuxian completed the duties of a librarian, he would receive daily rewards. Reading unparalleled books, he gained the Tiger Prison Skill. Preventing demonic cultivators from seizing secret manuals, he gained the Breaking Illusion Sword Intent. Expanding the library by one floor, he gained the Book of Cause and Effect of All Heavens. Repairing ancient books, he gained the Nine Heavens Profound Scripture. ... Time passed, and the world experienced several rises and falls, but the library remained steadfast. One day, the two strongest warriors in the world fought fiercely for a legendary immortal scripture, their sword energy clashing, the earth shaking, and countless lives lost, until they reached the library. To their astonishment, a hand emerged from the library, casually grasping two immortal swords. "Hundreds of years ago, I placed a 'Scripture of Compassionate Admonition' before you, hoping you would turn to good. Since you cannot reason with me..." Two fingers gently closed. The two immortal swords shattered into dust.
