When Li Yu falls asleep reading a webnovel about a ruthless, mute tyrant falling in love with a dainty male concubine, he doesn't expect to wake up inside the world of the novel—especially not as a fish!

Li Yu soon finds himself adopted as Prince Jing's pet carp, tasked by a less-than-helpful Magic System with preventing the prince from becoming a cruel tyrant. If he can accomplish this mission, Li Yu will regain his human form. Yet how can he succeed from inside a fish bowl?! See what fate awaits Li Yu and Prince Jing in this FINAL VOLUME!
