Who is the successor of the Seven Killing Orders of Ghosts and Gods?

The Seven Killing Orders of Ghosts and Ghosts originated in the Sui and Tang Dynasties, and was founded by the famous Taoist Yuan Tiangang, which combined the Taoist essence of Ma Yi School and Maoshan School. However, because this doctrine was so powerful that it leaked the secret, it was banned by heaven. In the end, Wang Xiaoer's ancestors inherited the Seven Killing Orders of Ghosts and Ghosts and lived in seclusion in the mountains.
