Deepest within Sunagakure's underground base, the Sandcastle, lay an utterly secluded chamber, completely isolated from the outside world by layers of barriers Toyotomi Yinglang had personally installed to block space-time interference, suppress energy, and isolate souls.
There was no light source, no sound, not even a movement of air.
There was only pure, seemingly solidified darkness, and within it, Toyotomi Yinglang's cross-legged figure.
He had sat there for seven days and nights.
Outwardly, he resembled a lifeless stone statue. His moon-white kariginu was spotless, and even the rise and fall of his breathing was barely perceptible.
But inside his body, deep within his tightly closed eyes, a "transformation" far more dangerous, grander, and more fundamental than any genetic experiment or energy impact in the Sandcastle had reached its most critical stage.
His consciousness had sunk into a boundless "inner landscape" composed of his own Eye Power, dragon essence, and spiritual will.
Here, there was no longer merely a scarlet background and an eternal pattern.
Countless images, streams of information and energy, and fragments of laws intertwined, collided, vanished, and were reborn. There was the Dragon Vein's vast solidity, the blasphemous distortion of the Evil God's power, the gentle vitality of Asura chakra, the precision and ruthlessness of the Ōtsutsuki "Karma," and the cold, powerful source of his own Eternal Mangekyō Sharingan's Eye Power.
Everything accumulated, analyzed, and extrapolated over the past several months, or even longer-all his knowledge, insights, and fragments of the essence of power-was forcibly gathered and smelted together at this moment!
With dragon essence as the foundation, forge an immortal body and provide Eye Power with an inexhaustible source!
Within the inner landscape, vast, dark-golden dragon essence slowly settled and stabilized like a pillar supporting the creation of heaven and earth, becoming a "land" that bore everything.
