Martial Arts: After Ten Years of Signing in the Cold Palace, I Am Invincible

Xiao Jue is the deposed ninth prince of the "Yan Dynasty". He was imprisoned in the cold palace with his mother since he was a child and suffered a lot of indifference. Everyone thought he was a sick and dying waste, but he was accidentally bound to the [God-level Sign-in System]. As long as he "signed in" at different locations, he could obtain various magical secrets, elixirs, and magic weapons. In order to protect himself and find out the truth about his mother's frame-up, Xiao Jue chose to "lie down" in the cold palace. He signed in silently for ten years and secretly accumulated enough terrifying power to overturn the entire dynasty.
