The spiritual energy returns unexpectedly, and the weak take the lead in mutating and evolving. In an instant, human beings fall from the top of the food chain to the lowest level and struggle to survive.
When the end of the world comes, the originally stable system collapses in an instant. Some people pursue power and profit and want to be emperors of the land. Some people pursue strength, fight against insects and beasts, and protect the country. Some people spread the doctrine, establish sects, and learn from the saints to teach the country.
And I just want a quiet environment for the rest of my life, but you bully me, fear me, isolate me, and plot against me. Since you won't give me a corner, then welcome me back from purgatory and make the whole world tremble under my feet.
