The Kamui Dimension was a strange realm independent of the real world.
Countless enormous rectangular stone pillars floated beneath its gray sky. The ground was made of cold, hard stone slabs, and the air carried a sense of eternal silence and isolation.
Yet now, that silence had been broken.
Thousands upon thousands of Naruto Uzumaki's Shadow Clones spread across every corner of the vast Kamui Dimension like a golden ocean.
Some sat cross-legged, brows furrowed, forming hand seals as they attempted to fuse chakra of different natures. Others stood with light flickering in their palms, lightning intertwining with fire, water clashing with earth, their failures marked by soft pops and muffled groans. Some even attempted such aggressive methods of fusion that they collapsed outright, dissolving into puffs of white smoke and sending their experiences of failure and pain back to the original.
The backlash of failure, rampaging chakra, and mental shocks surged through this alternate dimension, filling the once deathly silent Kamui Dimension with chaotic, violent fluctuations of energy.
As the countless Shadow Clones repeated their tedious, painful attempts, most of which ended in failure, a sudden burst of laughter erupted from one corner-wildly out of place, brimming with delight and smug satisfaction!
"Hahahahaha! I told you, the original's an amateur! Even after developing Divine Vacuum Attack, he's still an amateur."
The laughter came from a Naruto Shadow Clone who looked no different from any of the others.
He was waving his limbs excitedly, his right hand held high. In his palm, a mass of Jade Green light so dense it had almost become liquid slowly swirled and contracted, brimming with vitality.
Its warmth was entirely different from the violent or icy chakra-nature light produced by the other Shadow Clones' attempts.
Several nearby Shadow Clones were drawn by his laughter.
