Duan Jiaze, who was poor, inherited a private zoo after graduation, and was forced to download a “hooligan” APP called “Ling Xiao Hope Project”, which ushered in other “animals” such as Luya (golden crow), Daji (nine tailed fox), Bai Suzhen (white snake) and Black Bear. App will punish if he fails to complete its business-related tasks regularly.
