The world is a prison for deformed immortals and Buddhas, and also a prey for external gods.
The road of cultivating immortality that the world is busy with is a trap of polluted attachments. The stronger and more pious the people, the more complete the distortion will become.
Only Chen Ji, with his "non-attachment core", broke through illusions and purified pollution, and went from being a handyman in a deserted temple to a disruptor in the world.
The more he sheds his obsessions, the more absolutely rational he becomes, the more he can see the truth of the eternal scam, and finally return the stolen world to all living beings.
