Lin Yi, an ordinary urban youth, accidentally obtained a mysterious jade pendant. From then on, he had a portable space where various legendary mythical beast cubs lived. Just when he thought his life was about to be cheated, he found that he was being targeted by a group of stupid thieves - these stupid thieves were none other than the dads hired by the villain to steal the jade pendant!
These dads are all experienced in raising children, but they know nothing about stealing. Some of them held their children while visiting the spot, only to have the children cry and reveal their whereabouts; some forgot their tasks in order to coax the children; and some simply gave stolen items to their children as toys. Lin Yi found out that he not only had to deal with these stupid thieves, but also helped them take care of their children!
What's even more troublesome is that the cubs of the mythical beasts in the space don't stop either - the green dragon cub loves to tear down the house, the phoenix cub always wants to bake something, and the white tiger cub chases after the dads' children every day. Lin Yi had to deal with the mythical beasts and stupid thieves, using his wit and cunning to resolve one crisis after another.
However, as the plot progresses, Lin Yi discovers that the mastermind behind this incident is actually a mysterious organization who wants to use the power of mythical beasts to dominate the world. And the important task of subduing the mythical beasts, protecting the family, and fighting evil fell on the shoulders of an ordinary dad...
