All the People Are Suffering from Cancer, I Am Saving the World and Helping the People in the Health Center

The entire population has become cancerous and everyone is a wasteland! A hundred years ago, a curse came from heaven, and human lifespan could not last more than a hundred days. After death, a person can turn into a small world with mountains and rivers, and a red moon shining brightly. In every world transformed by a corpse, there is a terrifying cancerous creature that slowly accumulates power until it breaks out of its cocoon and causes chaos in the world. Some giants in the past have figured out ways to extend life. They can open the small world of the human body while a person is alive, find budding cancers, and kill them. Generations of ancestors have used their lives to prove it, and finally summarized a basic anti-cancer system ten years ago. From that day on. Doctors set out to save the world.
