The End of the World: My Assistant Is the Cause of the End of the World

Traveling to the end of the world when resources were scarce and steel beasts were rampant, Chen Sheng struggled for more than ten days before being sold to an intelligence organization in the desert. In order to have a stable food source, Chen Sheng accepted a debt that could buy 200 lives and started a garbage-like life. But the longer we live, the more we can feel the malice that this apocalyptic world has for mankind. A metal beast that doesn't understand hunger and thirst but eats people. A swarm of nanorobots whose nerves were cut off in the blink of an eye. Self-replicating mobile biofactory. Technology, technology, is still technology, but they no longer serve people. Just when Chen Sheng was almost killed by radiation, a highly intelligent robot's head fell from the sky. "What? The current apocalypse was caused by you? Whatever, I'm going to die, who cares what you have done." "What? You said radiation can cure it?" "What? You can fuse technology?" "What? Can you develop a time machine?" "You are so awesome, why did you choose to help me? What? Want to be human?" "Ahem, my name is Chen Sheng, a part-time doctor. From now on, you will be my assistant."
