Immediately after.
Uchiha Tenshu gave the command in his mind without hesitation: "Fragment of Heavenly Dimension, work with the Small World and suppress him with everything you have! I want to separate every part of him!"
Following Uchiha Tenshu's command, the Fragment of Heavenly Dimension, the Supreme Artifact, drew upon the power of the Twin Mud Gods' Small World and unleashed endless pressure upon Naruto Uzumaki's three-headed, six-armed giant Chakra form, completely suppressing both him and every movement of that giant form.
At the same time, Uchiha Tenshu used the authority of the Small World, amplified to the utmost by the Fragment of Heavenly Dimension, to instantly cause Ashura's three-headed, six-armed form to collapse.
Ashura's Will, occupying Naruto Uzumaki's body, clenched its fists in furious rage. Its bewildered, helpless eyes seemed to want to do something, yet there was nothing it could do.
Lacking the ability to think independently, it had no idea how to deal with this sudden change. It seemed that under the rules set in the past, there had never been any method for handling such a situation.
Even spatial transfer, which the original rules used against an invincible foe, was ineffective.
Uchiha Tenshu's Twin Mud Gods' Small World possessed a higher level of spatial density to begin with. This negated ordinary spatial transfer abilities, preventing enemies from entering this space or escaping from it.
Not to mention, under the effects of the Fragment of Heavenly Dimension, the spatial level had now been raised to the point where even if Kaguya Otsutsuki descended in person, she would be utterly unable to move freely through space.
Of course, a being like that
would not need spatial transfer to deal with Uchiha Tenshu's Twin Mud Gods' Small World. They could simply use overwhelming power to destroy the Small World
