Chen Yan, an ordinary office worker who works well, woke up one day and found that he had acquired a strange system-randomly adding someone else's professional skills every day. One day it might be a Michelin chef's knife skills, tomorrow it might be a construction worker's measuring skills. I thought it was useless, but I didn't expect that all these various skills would be used to take care of my four-year-old daughter, Xiao Nuomi. When the neighbor's children cry, he uses the skills of a psychological counselor to calm them down easily; for kindergarten parent-child activities, he uses the skills of a landscape architect to create stunning works. The originally deserted life became lively because of various intrusive skills and her daughter's smile. But secretly, a man with a twisted psychology began to stare at the father and daughter. He could not understand why Chen Yan could live such a happy life. An undercurrent was surging under the peaceful daily life.
