Interesting way of cultivating!
Still surprised that a rank 1 gu can cause damage to a half immortal body.

Cool, a new (very niche) path of cultivation, kinda similar to totem cultivation but not, at the same time, I feel like with this wooden aputure, Zhi is on his way to creating his own wood path extreme physique.
