The current Body Fusion Realm eventually merged three types of auras into one, transforming them into Primordial Chaos Energy. Simply put, he didn't need to comprehend any Laws like those of the Five Elements or Space. As long as he thoroughly understood Primordial Chaos Energy, he would be able to control these Laws.
The only thing he probably needed to comprehend was the Laws of Creation, which transcended all other Laws with its formidable essence. Creation represented fate, causality, and nearly everything else.
Mastering other Laws might not allow one to control all things in Heaven and Earth, but mastering the Laws of Creation meant everything would be at his will.
Lin Yi felt that once his understanding of Primordial Chaos Energy reached a certain level, he should be able to move freely between Heaven and Earth - and by Heaven and Earth, he meant not the sky and the land but the Immortal Realm above and the Cultivation World below.
