Twenty-five years after the end of the nuclear war, the earth has become a purgatory where alien beasts are rampant. Ling Feng, a wandering mechanic, can extract the cores of alien beasts and modify them into mecha parts with special powers, struggling to survive alone in the apocalypse. After being injured in an encounter with a high-level alien beast, he was rescued and taken in by Su Qing, a medical officer at Dawn Base. Ling Feng relied on his unique modification technology to build powerful mechas for the base to fight against alien beasts and win trust. However, he unexpectedly discovered that the mad scientist Dr. Chen was secretly capturing humans and alien animals for cruel experiments in an attempt to rule the world using gene fusion technology. Ling Feng and Su Qing teamed up to go deep into the tiger's den, vowing to destroy Dr. Chen's experimental base, uncover his shocking conspiracy, and protect mankind's last hope.
