Spiritual Qi Revival? No, the Apocalypse Has Arrived!

After sleeping for a hundred years, I reached the Golden Core stage. I was planning to descend the mountain and enjoy life among ordinary people. But instead of a golden age brought about by spiritual qi revival, I found a doomsday where corrupt spiritual energy was contaminating everything! Plants became monsters, animals turned into demons, and human Awakened Ones went mad with power! And I am the only purifier in the world. While everyone else scrapes by in the apocalypse, I treat forbidden zones like my backyard. "Warning! Ahead is an S-rank forbidden zone. The contamination level is off the charts. Not even gods and Buddhas may enter!" Me (taking a deep breath): "Damn, that's some potent stuff! I'll cultivate in seclusion right here today!"
