"The Code of Life" tells the story of Zhuang Yan, a top surgeon, who accidentally uncovers a genetic mystery spanning three generations when he rescues a young man who fell from a building. A rare blood type match and genetic garbled caused by a mysterious antibiotic allergy during the operation drew him into the vortex of illegal genetic experiments twenty years ago. At the same time, the relationship between retired professor Ding Shoucheng and a nurse triggered a genetic disease crisis. In the process of tracing her daughter's rare disease, pediatrician Su Ming discovered the concealed truth about her twin brother's birth.
As human cloning mysteries and newborn kidnapping cases broke out one after another, the hospital became a battlefield for the game of power and genes. In the ruins of the earthquake, glowing chimera trees emerged from the ground, connecting all individuals carrying Ding's genes, pushing humans to sign the "Bloodline Reconciliation Agreement" and rebuilding a new civilization on the ruins of genetic rights and ethics.
