Even though the opponent had already become the one within the Qingxu Sect who had ignited the most acupoints in hundreds of years.
The lack of ignited acupoints in the Enlightenment Realm had naturally determined that the opponent could not fully unleash the effects of the cultivation technique he had created.
In fact, the reason top-tier cultivation techniques were so powerful was precisely because they involved more acupoints, perfectly covering the acupoints ignited by the cultivator, thereby exerting stronger potency.
If the cultivation technique practiced was of a lower grade with less coverage of acupoints, its power would naturally be relatively weak, difficult to fully display an Immortal Cultivator's potential and strength.
*This was also why some cultivators chose to create their own techniques.*
