Ch. 521Tobirama: I'd like to visit Another World sometime too. Tetsuya: Wandering Tobirama?
Tetsuya explained the New Continent’s resources and his plan to connect it to the Shinobi World, while Tobirama asked to learn Breathing Styles and visit Another World. The chapter ended when Zabuza called Tetsuya with an update on his investigation into Shinnō.
- Tetsuya told Tobirama and Izuna that he planned to build a Scientific Ninja Tool Space-Time Gate to connect the two continents, and explained the New Continent’s land, sea, and mineral resources.
- Izuna went to read Tetsuya’s books after challenging Tobirama to finish them first.
- Tobirama learned that Izuna had used Breathing Styles, asked Tetsuya to teach him, and requested a chance to visit Another World.
- Tetsuya agreed to teach Tobirama later and thought about sending Obito to the Demon Slayer world.
- Zabuza called Tetsuya, who asked whether Shinnō had shown himself.
