According to Nezha, as a warrior, shouldn't you at least have an AoE skill for clearing enemies and a big move?
Yang Jian flipped through the Yuxu Immortal Technique. It certainly contained many Divine Skills, but most weren't compatible with his martial path. Either they required an excessively long cultivation time or consumed too many resources.
His cultivation of the Eight-Nine Profound Skills had already severely compressed his available time for training. Learning something else would inevitably delay his progress, so he decided to consult Nezha.
Nezha was particularly interested in matters like this. His cultivation level was that of a Golden Immortal, yet his abilities surpassed those of ordinary Taiyi Golden Immortals. Coupled with his vast and chaotic knowledge, he used the River Map and Luo Book to deduce techniques that could be used in the Primordial world.
