My name is Gu Jiuyuan. I'm a terrible student at Qingteng University, with eight failed courses. In truth, I'm the reincarnation of the Sword Venerable of Annihilation from the cultivation world.
My memories sealed away, I'm stuck living like a slacker in the city, snoring in class and chowing down on chicken legs. Everyone who sees me just shakes their head.
Then one day, I signed in at the library, and the System activated. My fate-defying journey began.
I sign in every day at the cafeteria, bathhouse, and dormitory, and the rewards keep coming: divine arts, magical treasures, and pills galore.
While everyone else is training for dear life, I get the ancient art of the Ultimate Scrub, Chaos Grime, from scrubbing people in the bathhouse.
The lunatic who once cut down three thousand Pagodas of the Buddha with a single sword is back, suppressing rifts to other worlds while eating chicken legs.
They think I'm useless, but they don't know I'm restarting the Age of Cultivation.
This city is actually a sealing formation, and I'm the only key.
After ten years of signing in, I've become the cultivation world's most fearsome big shot, looking down on all living things. Who dares call themselves a Venerable?
It's well written and worth recommending.
