In the Last Days, People Cultivate Immortality Alone

After Feng Buyu died unexpectedly, his soul traveled to a strange world - the end of the world, which is full of dangers. Natural disasters are commonplace; the land is like a wasteland; mutated monsters are raging; and a zombie kingdom is established. A small group of humans are clinging to life, but they are still... Fighting among themselves. As the saying goes: the poor rely on mutation, and the rich rely on technology. After the brave man undergoes brutal experiments, he has a small chance of obtaining evolutionary mutations and becoming a person with superpowers.

Fight against the apocalypse with mankind's highest technology and deepest courage.

A sound of nature sounded in my ears: [The Immortal System has been activated] Feng Buyu stopped the staff: "I don't want to mutate, I want to become an immortal!"
