What is the identity of the horse in the paper burner's novel?

Ma Bubu Seed, a paper burner's novel, is a knight-errant motor. He has been taught by different people since he was a child, and he is proficient in ghosts and gods with different skills, and has dabbled in Yin and Yang, gossip and geomantic omen. He has done many admirable things, and the Jianghu people call him Yang. It is derogatory to call him banxian now, but it was definitely positive to put him aside at that time.
