If taken a step further, one can delve deeper into tracing the opponent's chain of cause and effect, gaining insight into all their past experiences—master's heritage, cultivation path, ties with friends and foes, enmities with arch-rivals, debts and sins of killing karma, and even those deliberately hidden and erased secrets of the past (such as possession, life chart swapping, betrayal, etc.) can all be fully restored.
Simultaneously, it can see through the causal ties on the opponent, knowing the backing they rely on, the arch-rivals they fear, and the hidden trump cards, treasures, and fortuitous encounters they hold.
