Shin Uchiha stood at the highest point of the Spatial Island and gazed into the distance, his heart swelling with pride. This island belonged to him. More importantly, he could sense every last thing within the space, as though he were a god with everything here under his control.
Once Shin Uchiha snapped out of that feeling, he focused on his Eternal Mangekyō Sharingan and carefully examined how far his dōjutsu had evolved and what enhancements they had gained.
First was his dōjutsu-Takamagahara. Its evolution had expanded the entire space and greatly strengthened Shin Uchiha's control over it. If an enemy invaded, he could not only sense them but also track their location at every moment. In addition to expelling intruders, he could move them anywhere within the space at will and use its power to pin them in place.
Outside the space, Shin Uchiha could now track the locations of people marked with a space mark. Moreover, anyone whose chakra was below Kage Level would be utterly powerless to resist his Eternal Mangekyō Sharingan. He could draw them into the space and suppress them there.
Next was his dōjutsu-Kotoamatsukami. Its effect remained unchanged: anyone subjected to it would fall under its control silently, without ever realizing it.
The greatest change to Kotoamatsukami was that its cooldown had shortened further, dropping to one month. Moreover, with Shin Uchiha's Mangekyō Sharingan evolving into the Eternal Mangekyō Sharingan this time, Kotoamatsukami was already available for use again.
His dōjutsu-Instant Space-Time-had already been enhanced twice since Shin Uchiha acquired it, even though he had never used it. After this evolution, it could be considered the strongest genjutsu apart from Kotoamatsukami. The time, space, matter, and living beings within it were all created and controlled by the caster, and it also inflicted mental attacks.
