Fang Chengping is an ordinary odd-job disciple who gains the mysterious ability to enter and leave other people's dreams at will.
In his dreams, he gains nearly all the dignity he could want. The cultivation techniques and martial skills he obtains help him shed his useless reputation in an instant and earn a place among the formal disciples.
But unexpectedly, every gain comes at a cost. Unable to establish his foundation, he is sent back to being an odd-job disciple.
From then on, the sect has an odd-job disciple who flops down and sleeps at every opportunity, while the Three Realms of humans, immortals, and demons gain a God of Sleep.
