In the "Magic Wand" Great Arcana Sequence, Zheng Qing's title is 'World'.
He also has a Forbidden Curse Sapling.
And the Forbidden Curse is a magic that transforms the concept of 'World' into a spell through 'convergence', a spell-based world and universe.
Therefore, from a very early time, he has been particularly sensitive to the word 'World'.
World and Universe are two different concepts.
Zheng Qing is aware of this.
In the "Wizard World Encyclopedia", the void worlds are categorized into four levels according to size, the strength of laws, etc.: Secret Garden, Secret Realm, Small Thousand, and Great Thousand.
And the sum of all worlds, along with what lies beyond them, is what is called the Universe.
