Ning Yuan has been feeling rather weak lately.
In his dreams, his cold and beautiful homeroom teacher becomes a seductive spy for the Demon Sect;
His aloof school beauty desk mate becomes a fragile cultivation partner, watching through tears as he is bullied in a grotto;
Even his sister, so pure and detached that she seems to lack any worldly desires, becomes a dignified sect leader in his dreams, imperious to everyone but him, and willing to teach him everything she knows.
Ning Yuan, basking in their tender affection, thinks it is a blessing from heaven, until one day his usually well-behaved junior schoolmate grips his chin and slips a still-warm pill into his mouth:
"Master, whether in the past or now, you can't escape me..."
Only when the chains lock around his ankles does Ning Yuan realize in horror that those ravenous immortal maidens have all come after him.
