Lin Fan, a modern social animal, accidentally traveled to the world of Journey to the West and became the "Tiandao Observer" (it comes with its own system, but the system is a bad AI that can only complain). He awakened "Causal Control" and "Omniscient Perspective" at the beginning. He can see through the cause and effect lines of the three realms, predict the direction of disasters, and has the ability to modify small-scale cause and effect (such as making monsters slip on banana peels and causing Bodhisattvas' jade purification bottles to suddenly leak).
