In the radiation-ravaged, resource-poor Ashes 7, everyone thought Jiang Muxian was a cowardly and useless restaurant owner. No one knows that he contains the empire's top genetic experimental product "Taste Core" inside his body, which can repair genes, improve food, and analyze all things. He is the experimental subject No. 7 Who escaped from the top-secret laboratory that year.
He kept his name anonymously and guarded a shabby "osmanthus stove", warming the wasteland refugees with bowls of hot rice and dishes. A mysterious visitor gives a star fire pepper that has been extinct for three hundred years. The mechanic girl Su Ya accidentally breaks in. The Owl Eagle Group comes with force, and the peaceful life is completely shattered.
In order to protect the people around him and reveal the truth about his life experience, the restaurant owner who once only wanted to live a stable life will eventually use his cooking skills as a blade and the power of genes as a shield to make his own way in the world on the interstellar wasteland.
