In Imprisoned In The Demon-Locking Tower Signing In For Three Thousand Years Emerging Invincible, Zhao Fan is cast into a place meant for the forgotten—a prison filled with ancient demons and certain death. With no cultivation and no allies, survival seems impossible.
Then he discovers a system: sign in.
What begins as a desperate act turns into centuries of silent accumulation. While the outside world changes, Zhao Fan remains in the Demon-Locking Tower, steadily growing stronger—day by day, year by year, for three thousand years.
When he finally steps out, he is no longer the discarded cripple. He emerges as a sword immortal whose power defies comprehension, shaking the cultivation world with a single strike.
Forged through patience rather than talent, Zhao Fan proves that true strength is not built in moments—but across millennia.
