Primordial Mountains and Seas

In 2140, the combined impact of nuclear warfare in the Third World War and natural disasters brought about the end of the world. Tens of thousands of years after humanity's extinction, Earth began to evolve once more. Microorganisms on the ocean floor mutated under the influence of radiation, growing into strange and ferocious beasts. A new humanity also emerged through evolution. Unable to grow stronger by absorbing radiation, the frail humans formed tribes to survive in an age of floods and beasts, joining forces to fend off their attacks. Yet, by chance, humanity also discovered a way to mutate and grow stronger, which they called cultivating the Dao to become a god. This is the story of the protagonist, Shixi, cultivating the Dao and becoming a god in an era known as "Primordial Chaos," and founding a new age.
