The reason why the octopus cat had the illusion that the powerful butterfly was still here was all because the Mirage Butterfly had profound attainments in space and arrays.
It was because she had dozens of max-level mythological skills, a principle of space that had already risen to over level 100, and attainments in array techniques that were only weaker than her divine-level illusion, spatial, and spiritual talents that she could use the composite array with such ease.
Rather, in the evil world, quite a number of living beings specialized in array techniques. Otherwise, there wouldn't have been so many evil arrays in this evil space.
The level one and level two evil arrays that the Mirage Butterfly had to destroy were only slightly weaker than the "absolute" and "ancient" series of arrays. Just like how some human names had "sequences" in them, the arrays were also graded.
