Programmer Gao Yuan was slapped in the face for complaining about his boss. He accidentally activated the "Thousand Realms Evolution System" and gained the ability to collect plant genes. The first task of the system was to let him make friends with the daughter of the company goddess, so Gao Yuan became a part-time dad. While taking care of two little lolita with superpowers-one can read minds and the other can communicate with plants, he also deals with the harassment of local gangsters. When the gangster leader Zhao Ting comes to visit, Gao Yuan discovers that his life as a nanny is evolving into a bizarre evolutionary battle related to the survival of the world. He must use the system's capabilities to protect his children while uncovering the conspiracy of the mysterious organization behind it.
