"Whew, this sight really is familiar."
Imu floated in midair, his hands clasped behind his back.
His golden eyes, sharp as an eagle's, gazed indifferently down at the vast, desolate, cratered, uneven gray-white earth below.
When he looked up, countless stars, a brilliant sun, and an expanse of utter blackness filled his vision.
This was the moon—the Shinobi World's moon.
Like Sea Star, it also had oxygen capable of sustaining life.
But according to the Academy of Sciences' previous investigations and research,
Sea Star's moon and its other satellites had oxygen because the White-White Sea and many Sky Islands expanded the atmosphere's reach, conveniently encompassing the surrounding satellites.
The Shinobi World had no similar conditions, so where had the moon's air come from?
Imu was not a scientist, but he was a transmigrator.
According to his memories from before transmigrating, a spatial passage existed between the Shinobi World's moon and its Earth.
Perhaps oxygen had been introduced to the moon through it, especially into its underground interior.
After all, Hamura Otsutsuki's descendants had lived inside for nearly a thousand years.
As for why the moon's surface also had oxygen, and why it had not leaked away into space,
it might have been because the Great Tenseigan generated such powerful gravity that it firmly held most of the oxygen around the moon.
The complete Great Tenseigan possessed the immense power to push the entire moon toward the Shinobi World Planet and send it crashing down.
This proved that it possessed extremely formidable gravitational capabilities.
"By that logic, wouldn't the air on this moon be constantly leaking away now?"
Imu swept his gaze across the starry sky overhead as he thought to himself.
Because the Great Tenseigan had already been taken to Sea Star by Masato, who had adopted the Hyuga name.
