In order to save his seriously ill daughter Xiaoyu, single dad Lin Feng accidentally entered the closed parenting base of the top wealthy Qin family. With his extraordinary infant care skills, he was recruited by Qin Xiao into the mysterious "Natural Selection Parenting Institute" as an exception. As his authority escalated, Lin Feng discovered that the institute used gene editing technology to deprive babies of their emotions and create cold-blooded heirs in batches. His late wife Su Wan was killed for revealing this secret. Lin Feng, who pretended to be loyal, teamed up with Dr. Chen, a conscientious scientist, to sneak into the core database and find the incriminating evidence left by Su Wan. When Qin Xiao attempted to genetically modify Xiao Yu, Lin Feng launched a revenge: exposing the data, paralyzing the laboratory, and using the "perfect heir" cultivated by Qin Xiao to fight back. In the end, the wealthy family collapsed and the institute was transformed into an "emotional education center." Lin Feng reshaped the system with Su Wan's parenting philosophy, allowing love and humanity to return to the cradle.
