Lately, Yuya had felt increasingly uneasy.
He began stepping up Hagoromo and Hamura's training,
hoping they would soon reach their strength in the original story and advance to the six paths level.
By then, Hagoromo and Hamura were already thirteen.
Under Yuya's guidance, they could already wield Yin-Yang Release with ease and form Truth-Seeking Orbs,
enter Six Paths Mode, and manifest a complete Susanoo.
Yuya also taught them Sage Mode and Space-Time Ninjutsu.
Their strength grew rapidly.
The power of the God Tree and the Ōtsutsuki was being drawn out.
Yet even so, Yuya felt it was not enough.
Meanwhile, the Silver Dragon returned as well.
It had been staying in a Dragon Vein within the Ancient Kingdom of Roran, which appeared in the movie.
The original story had explained that the Dragon Vein's immense power could even allow travel through time and space.
Naruto and his father, the Fourth Hokage, Minato Namikaze,
had once met in a special space.
But after investigating, Yuya discovered that this supposed time travel
was merely a special gravitational field formed by the Dragon Vein's immense power.
It could project spaces and powers from different points in time and space into a special space, allowing them to interact briefly.
Like a mirage or a reflection in water, it involved no actual travel through time and space.
Even so, that was enough to demonstrate how extraordinary and powerful the Dragon Vein was.
The Silver Dragon had been nurturing itself within that Dragon Vein.
Now, it had finally appeared again.
Its body was even larger than before, and its draconic aura had grown more imposing.
It sought out Yuya
and settled with his family in the city floating in the sky.
Over the past few years, the Great Xia Empire had grown ever more prosperous.
