Mortal World!

All things have spirits, and human desires change over time. The upper class, the middle class, and the lower class, each class has its own thoughts; the gods of Yang, the earthly world, and the ghosts of Yin are all struggling. Only by being in it can you truly feel the situation of each class. But once you enter the situation yourself, you can easily get lost in the chaos. Entering the game, breaking the game, and returning to the true nature, every living being is striving for this. Observing the various forms of life in the mortal world and understanding the laws of natural operation are ultimately to find a way to break the situation.
