Bai Zemin had managed to obtain a lot of information after arriving in this alternate dimension with the help of the Throne of Creation; even if such information could not be confirmed 100%.
In the past he had no choice but to miss many clues, because even if they passed in front of his eyes, Bai Zemin would never be able to see them let alone understand them. At the end of the day, he barely knew himself not to mention the secrets of the cosmos and much greater things.
However, now that his strength was comparable or even higher to that of a maximum soul evolver and on the edge of the boundary between a Lower Existence and a Higher Existence, he was finally able to see things he didn't before and draw a conclusion or two based on what he had learned so far.
