Kamui Dimension.
After using Zero-Tails to consume a large amount of Nine-Tails Chakra, Obito had remained inside the dimension without leaving.
Obito had given up Ancor Vantian, the aircraft, precisely to evolve his own Sharingan.

"Looks like I still have to cooperate with Black Zetsu to find these Jinchuriki. But will Black Zetsu still be catching tailed beasts now?"
Zero-Tails spoke leisurely from the side.
