In order to complete the system tasks, Su Changqing went to the lunatic asylum to recruit disciples. He looked at these crazy old people who were rejected by their families. "The deadline is approaching, will you choose to slay demons with me and increase your longevity, or will you rather die of old age in this lunatic asylum?" Everyone thought Su Changqing was crazy. But who knows, a hundred days later, the ghost tide will be in chaos! His disciples appeared out of nowhere! "According to the master's command, I will ride on the wind with my sword to eliminate demons in the world!" This novel and its characters are purely fictitious.
