According to what he saw, the black and white universal virtual reality was a fake copy of the universe created by the God King of the Gemini race.
Everything in this fake reality is under the God King's control, including the flow of time. So the God King can speed up or slow down time.
He also learned that every member of the Gemini race can access the black and white universal virtual reality and use it to train. They do this by recreating their Supreme Metacs in the fake reality and training with it.
In the fake reality, they don't have to worry about the cost of divine crystals or the production of Entropy, as the rules of the fake reality can be tweaked in their favor. When combined with the faster time, a day in the real universe can be a year or a hundred years in the fake reality.
'This should be how that little shit that I gave birth to was able to progress so fast even though we became Dao Lords on the same day,' he thought in realization.
