There were times in life where the solution to one's most pressing conundrum was literally directly within one's grasp and it could be missed entirely. It wasn't because the person was unintelligent or forgetful, simply a link between the problem and the answer had never revealed itself within one's mind.
Wei Wuyin had access to Void Astral Force, Void Energies, and not once did he ever link it with Void Gates. This was because the concept of the Dao of Void was so broad and confusing that he simply never considered it.
What was the Dao of Void?
According to Kratos at the moment of his transformation: The Dao of the Void related to space, time, astrological forces, and void energy. Space was divided into fixed, stable, chaotic disturbances within the Dark Void and its various forms, including atmospheric space. Time was divided into the past, present, future, isolated, and paradoxical temporal periods of existence.
