Immortal Law, or Immortal Technique, is a method that surpasses Heavenly-level cultivation techniques.
Su Chengyu inquired about the Heaven-Mending Stone's knowledge in this regard, and according to the Heaven-Mending Stone, Immortal Techniques are divided into two types.
One is ordinary Immortal Law, the other is Supreme Immortal Law.
Su Chengyu possesses some cultivation techniques that have already reached the threshold of Immortal Law, but he has not truly grasped their True Intent; from the surface, they seemed no different from ordinary techniques.
Among these, the True Dragon Treasure Technique and Phoenix Divine Art are the most typical examples. According to the Heaven-Mending Stone, these inherited arts from the True Dragon Clan and Phoenix Clan are top-notch even among ordinary Immortal Laws.
However, Su Chengyu can only rely on combining the two techniques to achieve a level equivalent to Immortal Law.
