Modern young man Chu Luo traveled through the world of immortality and became the least qualified outer disciple in Shushan. After failing the entrance examination, he was sent to the dangerous Demon Locking Tower as a handyman. In a desperate situation, he accidentally activated the god-level sign-in system, signed in at holy places such as the Demon Locking Tower, the Sutra-Tibetan Pavilion, and the Treasure-Tibetan Pavilion, and obtained various super powerful skills one after another. He counterattacked all the way, slapping fellow sect members who despised him in the face, thwarting the inner sect's geniuses, exposing the sect's traitors, joining forces to destroy the evil stronghold, and even awakening the heaven-defying sun body. From a handyman who was despised by everyone, to the leader of the Kunlun Demon-Conquering Conference, Chu Luo relied on the system to soar all the way, sweeping the path of cultivating immortals with an invincible attitude.
