Betting Against the Sky, My Divination Is a Secret

The sinister little Taoist priest Zhang Xiaoxuan traveled to another world and started a divination system. This divination is super effective and responds to all requests. The price per session is terrifyingly expensive. Attribute is 0, no capital? Then use the body as a hexagram material; What? Does it also carry a probability of failure? If Brother Pingtou refuses to accept it, just do it and come back after collecting all the hexagram capital; Does this system increase the probability of failure? If you change again, I, Zhang Xiaoxuan, will win against you. Is this divination actually a secret from God? Look at me, Zhang Xiaoxuan, using heaven as a hexagram and the world as a disk, I can figure out a heavenly path.
