The so-called "Dragon Palace."
It was merely a dwelling built in imitation of ancient human texts by sea beasts that had gained sentience, using the chakra within seawater infused by the God Tree's roots.
Only by invoking the name of Indra's reincarnation had the Sage of Six Paths barely managed to enter the Dragon Palace.
After all, the Rinnegan could not be faked.
The sea beasts, mostly whales and sharks, looked timid and pitiful, drawing a faint sneer from the Sage of Six Paths.
The undersea tremors caused by the merging archipelagos seemed unable to reach this place, turning it into an ideal paradise cut off from the world.
As he walked, the Sage of Six Paths secretly kept his gaze on the sea beasts drifting forward amid the currents swirling around them.
Natural Energy.
No matter how faint it was, the Sage of Six Paths saw this primordial power of the planet within the networks running through the limbs and bodies of the sea beasts.
The land had undergone its changes; naturally, the seabed had undergone its own transformation as well.
It was merely the Sage of Six Paths repeating what he had done a thousand years ago, once again teaching the myriad living beings how to wield power.
The waves.
Finally receded.
A few lingering sprays remained atop the mountain-like earthen barrier, their rippling reflections gleaming beneath the sunlight.
Once the sea tide, the same color as the blue sky, had withdrawn, the people who had held back the waves saw the true form concealed beneath the currents: a translucent expanse of deep, heavy brown, like the earth itself.
The continent had already formed. It had merely been hidden by the tides stretching to the horizon, so no one had noticed the changes beyond the islands.
"Divine miracle!"
