Lu Xiaomao, a well-known dandy in the imperial capital, spends his daily life walking birds, teasing dogs, and teasing young ladies. Until one day, he accidentally broke a broken stone in his ancestral antique shop--a funny cub who called himself "ancient ferocious beast Qiongqi" jumped out of it.
This Qiongqi doesn't eat or drink water, and only eats "negative emotions". What's even more outrageous is that it can also help Lu Xiaomao awaken the "emotional fruit" ability: whoever has ill intentions towards him, he can turn the other person's ill will into various weird abilities. From then on, Lu Xiaomao's life went completely wrong.
An "anti-trick master" suddenly appeared in the dandy circle of the imperial capital: when others framed him, he tricked them into bankruptcy; someone sent a killer to assassinate him, and he deceived the killer into his younger brother; the rich second generation wanted to spend money on him, so he opened an "emotional exchange" on the spot, making the rich second generation cry and beg to be a wage earner.
However, as Qiongqi grows up, Lu Xiaomao discovers that things are not that simple - the hidden beast hunters in various major families, the mysterious organization "Beast Control Bureau", and the "broken ancient seal" mentioned by Qiongqi... All clues point to a shocking secret: underground in the imperial capital, there is a seal tower that suppresses ancient beasts.
And he, Lu Xiaomao, is the chosen "Tower Keeper"
