"Third-stage Susanoo. He couldn't keep burning through his ocular power so recklessly for long." Obito Uchiha sighed in disappointment. He still hadn't gotten a look at Uchiha Sōken's ocular techniques. Since Sōken had already resorted to using Susanoo at such a cost, there was no way he'd waste more ocular power on his Mangekyō Sharingan's techniques.
Still,
it hadn't been a complete waste.
Obito had never used Susanoo himself, but according to Madara, it consumed an incredible amount of ocular power. The higher the stage, the greater the cost. Third-stage Susanoo was already a massive drain; after using it only a handful of times, the Mangekyō Sharingan would go blind.
"Obito, do you want to keep watching?"
Black Zetsu asked.
"No. Just leave a few White Zetsu here to keep an eye on things." Since he couldn't learn the secrets of Sōken's ocular techniques, there was no point staying. Rather than waste time watching Sōken slaughter Root's shinobi, Obito might as well return to Kirigakure and plan the coming war between Konoha and the Mist Ninja. He could use the Mist Ninja to wear down Sōken's Mangekyō Sharingan.
As for Konoha,
they were already killing one another in rivers of blood without him lifting a finger!
Besides, the Byakugan was far too troublesome. He had to be extra careful while operating in Konoha, so the Hyuga wouldn't discover his whereabouts. He wasn't planning on exposing himself this soon. By comparison, that miserable place, Kirigakure, was much more comfortable.

The air suddenly twisted,
and Obito's figure rapidly shrank with the warped space, drawn into his own dimension. Seeing this, Zetsu closed the pitcher plant over his head. He
