Throughout Jianghu history, martial artists who used poison had always been few and far between, because poison arts were simply too difficult to cultivate.
Strictly speaking, poison arts were also a type of demonic-path cultivation method, only even more extreme and sinister.
Such methods were rather popular at the Postnatal Realm and Xiantian Realm, their power formidable enough that they could sometimes instantly kill martial artists of the same rank.
However, once one reached the Spirit Transformation Realm, the decline of poison arts became apparent.
Spirit Transformation Realm martial artists possessed powerful true qi. Even if they did not deliberately temper their bodies, their physical strength would naturally grow alongside their cultivation.
For that reason, ordinary poisons could no longer do anything to them. Martial artists cultivating poison arts had to seek out even more powerful toxic creatures and fuse them into their bodies, or their combat strength would only grow weaker and weaker.
But in doing so, poison arts lost their sole advantage.
After all, fusing toxic creatures into one's body was an act that harmed others only after harming oneself. Even with the secret methods of poison arts, it still took a great deal of time to suppress and refine those toxic creatures. The effort and time required were simply excessive.
