It turned out that the method used by the Space God King back then was to directly use his spatial ability to contain a world within a small piece of space. Then, when needed, he would simply break that space to release the contained world. In that situation, even with the power of the Divine Emperor's treasure, Zhou Tian could not erase the opponent's technique.
Every advantage comes with a disadvantage. Although Zhou Tian was indeed stronger than the Space God King by relying on the Divine Emperor's treasure, he still had no way to counter the Space God King's technique at that time.
The Space God King used his spatial ability to contain a world within a small area. Although it seemed incredible, the technique he employed was akin to the manufacturing principle of ordinary storage equipment. While it appeared magical, besides the terrifying size of the object he contained, the Space God King merely used the simplest spatial ability.
