Through the "Decomposition Combination", the Hundred Transformations Stone could realize its Hundred Transformations ability. As long as the level of these two skills was high enough, they could transform into anything.
If a Hundred Transformations Stone in the form of a Rubik's Cube wanted to become a triangle, it might require entry-level Hundred Transformations.
But if it wanted to go from a Rubik's Cube to a complicated fighter plane and mecha, it might have to use skills with higher proficiency.
Moreover, just the skill level was not enough. After all, the Hundred Transformations only determined its appearance. If it wanted the accompanying ability, it still had to use the mechanical life form in the Hundred Transformations along with other mechanical equipment to complete the transformation to increase strength.
