When Musk collected the Void Walker chapter, intense information seemed to flow in his mind, this all was digested, and he seemed to understand that the Void Walker scripture was imprinted into the void. The person capable of accomplishing this is obviously too strong and the requirements for getting the next chapters were very simple, he just had to comprehend the one he had.
More than just that, it seemed to make him scared because he had read some information about the higher dimension in the library, and that allowed him to understand that other realms seemed to exist beyond the Realm Lord stage, and all of them were divided based on the understanding of Dimensional principles. The so-called immortality, that Realm Lords and above realms had was all based on dimensionality. Once one reached the stage, even though they could view themselves as immortal, this was all relative to the dimension. The same principle seemed to be comparable to the power of heaven and earth.
