The soul of Lin Fan, a time traveler, traveled to the West and resisted the journey, but the "behind-the-scenes causal system" was activated. Whenever he makes an abnormal choice, changes the established plot, or triggers a conflict of cause and effect that does not exist in the first place, he can obtain rewards of merit, magic weapon, supernatural power and even realm improvement. Lin Fan decided not to be that resigned ascetic who only chanted sutras. On the surface, he is still compassionate, but secretly he gives instructions through the system, either cleverly guiding or directly intervening, so that the apprentices no longer play according to the routine. Along the way, the established cause and effect are constantly being broken, causing headaches for Heaven and Lingshan. The planned disaster has been repeatedly changed, and the behavior pattern of the Buddhist scripture-seeking team has shocked the gods and Buddhas of all parties.
