On the open sea, hundreds or perhaps thousands of nautical miles east of Japan's Kyushu Island, the sea bulged high. Tens of thousands of tons of seawater surged skyward in a mountain-sized crest, then spread outward in a sweeping tsunami as an enormous Turtle Island bearing a mountain range surfaced.
"So this is the Turtle Island the Uchiha Clan tamed..."
"Before the Age of Gods ended, the Uchiha ancestors moved Konoha's ruins into hidden realms and onto Turtle Island's back."
Uchiha Senmon and Uchiha Itachi walked across Turtle Island. Although it had previously been submerged in the Pacific Ocean, the soil on its barren back showed no trace of moisture. It was unusually dry.
Was it a barrier?
Uchiha Senmon lowered his head after looking up at the sky and glanced around. Some washed-out, abandoned building materials and wrecked boats still remained on the island.
"It seems we had uninvited guests during the time Turtle Island reappeared in the human world," Uchiha Itachi said mildly.
With Uchiha Itachi leading, the two walked one behind the other, first arriving at the waterfall on the main peak.
They walked across the pool's surface and passed through the plunging torrent of the waterfall. Before them was an entrance blocked by rubble.
At Uchiha Itachi's signal, Uchiha Senmon raised his hands and formed a seal. Roots burst through the rocks, opening an entrance wide enough for a car to pass through in an instant.
Although the cavern was dim, it posed no difficulty whatsoever for Uchiha Senmon with his Sharingan activated.
His gaze swept over two rows of headless Buddha statues holding sword seals, then settled on the enormous demon reliefs on the rock wall.
