Immortal Arrival Is Strange

In this world, evil spirits are rampant. Nine out of ten people who attain enlightenment and become immortals are crazy. Insect eggs eat away the body, raise human animals in captivity, and even regard mortals as "blood food"... Chen Mu has eaten carrion, dug out maggots, and danced with madness since he was a child. In an accident, he mistakenly entered an ancient cave. All his playmates rotted and died, but he survived. From then on, he often dreamed of returning to the Linghuan Immortal Realm and had a glimpse of the fate of immortality. But I was shocked to realize that the principles of cultivation in the two worlds were completely contradictory! Which path is the real way to become an immortal?
