Lu Chen, a night-shift clerk at a convenience store hidden among ordinary streets, is actually an undying Immortal Lord who has endured ten thousand years of tribulations. When ancient demon blood seeps from a bronze mask, the four disciples he once enlightened fall into danger one after another:
The demon-subduing sword of Xuanxiao, the Kunlun Sword Immortal, turns crimson.
The energy core of Mo Xuan, the Mecha Empress, runs out of control.
The seal of Honglian, the reincarnation of the Dark Phoenix, nears collapse.
The nirvana flames of Qingluan, the Demon Emperor, turn blood-red.
And the Nine Nether Demon Lord, newly freed from its seal, takes the form of twin little girls, Ye Jin and Yue Xi. By day, they clamor for lollipops; by night, they try to climb into his bed to drink his blood.
Amid this catastrophe spanning cyberpunk cities and primordial battlefields, Lu Chen discovers that his greatest tribulation is the tenderness he carved into his disciples' souls with his own hands all those years ago.
"Master, this time we're going to raise you." The four female emperors trap him in a time rift, while the Nine Nether Demon Lord whispers with a laugh in his ear: "Immortal Lord, guess which will break first... your Dao heart or your back?"
