After dealing with Tuguhou,
Chen Mu efficiently handled the corpse. After a search, he found no Spiritual Objects, but he did discover a beast skin in the belongings of the deceased.
The beast skin featured many human anatomical drawings and some Foreign Race languages. It seemed to be a type of Martial Arts Technique. Chen Mu surmised it was likely the same kind of 'Shamanic Barbarian' method that the other had deployed.
The Shamanic Barbarian Method is actually also a kind of Martial Arts.
Compared to the present Martial Arts, the Shamanic Barbarian Path is more primitive, imitating the moves and energy flows of top-level mythical beasts that once existed, learning directly from them, much like the Tiger Demon Bone Tempering Fist, etc.
