Earth, water, fire, wind, light, dark, and chaos were not only the seven main elements of Anril, but were also seven major laws. There could be numerous laws that extended from each of these elements, whereas the laws of three elements—namely light, dark, and chaos—were the hardest to master. The ones who could master these most fundamental rules would be as great as the five Dragon Aspects. Despite being talented and having great potential, it would be impossible for Lin Li to grasp these outrageous rules before reaching the Legendary-realm.
In fact, it would be unlikely for him to do so even if he got into the Legendary-realm.
By estimation, Lin Li felt that he would only be able to master these two fundamental rules when he got closer to the Sanctuary-realm.
