Breaking through to Qi refinement Level 4 meant that one had become a middle-stage Qi refinement warrior and had strength that was countless times stronger than low-stage Qi refinement Warriors!
For example, once one became a mid-tier Qi refinement warrior, one would not need to pay any spiritual herbs to the sect. The sect would even distribute cultivation resources to them. What was even more surprising was that the sect's Sutra library would be open to the disciples. Disciples who had advanced to Qi refinement Level 4 could go to the Sutra library and receive a low-level Yellow-tier spell technique for free!
This kind of spell technique was not something that the low-level fireball spell could compare to.
It could be said that a fourth-stage Qi refining cultivator with a spell technique could easily take care of three ordinary third-stage Qi refining cultivators. The gap between them could no longer be described with a number.
