Lin Mo is an ordinary takeaway boy who lives in poverty and rushes around the streets of the city every day. During an accidental meal delivery, he found a little girl in an abandoned cardboard box who claimed to be the reincarnation of the ancient beast "Taotie". This little girl looks cute but has an amazing appetite. She eats up half a month's salary of Lin Mo every day. She always threatens him in a soft childish voice: "If you don't buy me fried chicken, I will eat your luck!"
Ever since he adopted this little ancestor who called himself "little gourmet", Lin Mo's life has completely gone astray. When he was delivering food, he was stopped by a young and beautiful female CEO to confess his love; when running errands for shopping, a popular celebrity lady asked for her WeChat ID; even the aunt who sold pancakes downstairs insisted on introducing her niece to him. The most outrageous thing is that the girls who are chasing after him all have a faint black aura floating on their bodies.
As the time spent with "Little Tao" increased, Lin Mo gradually discovered that this little girl who claimed to be an ancient ferocious beast was indeed something special - she could see things that ordinary people couldn't, predict the future, and even affect the fortunes of people around her. As for the girls who pursue Lin Mo, the black energy on their bodies turns out to be a curse called "Emotional Evil", which will gradually devour people's vitality.
Lin Mo accidentally activated a golden finger called the "Taotie System". The system required him to complete various tasks to feed the "little Taotie" and at the same time help the girls who were cursed by the "Evil Love". As the mission progresses, Lin Mo discovers that there is a huge conspiracy hidden behind the "Qingsha" curse, and the true identity of "Xiao Tao" is closely related to this conspiracy.
