As Hyuga Yu fully unfolded the connection between his Extrasensory Perception and the natural energy in the atmosphere, the air around him twisted and the ground began to tremble. Vast amounts of natural energy dispersed through the atmosphere surged wildly into Hyuga Yu's body along several visibly distorted channels of air!
Hyuga Yu directly mobilized seventy percent of the natural energy within a twenty-kilometer radius, gathering it toward the center of the Forest of Death. Along the path of this channel, barren soil rapidly sprouted green grass, withered flowers raised their heads and bloomed anew, and even uprooted trees took root again and regained their vitality. Even the air became fresher and sweeter.
Then Hyuga Yu's gaze sharpened as he once again activated Yang Release: Organic Mutual Devouring, connecting it to the incomplete Giant Tenseigan.
What he was doing was, in fact, based on the same logic the Giant Tenseigan had deduced: using Yang Release to save itself.
The difference was that Hyuga Yu had succeeded in saving himself because he had gained the ability of [Conversion] in the world of Detachment.
Being able to freely convert the types of chakra and even natural energy was what allowed Hyuga Yu to keep his body, which had been on the verge of collapse after losing the Hashirama Cells, stable.
Put more simply, ninjas were like trees without roots. They squeezed their own bodies to produce chakra and gain power beyond that of ordinary people.
Sages were the complete opposite. By absorbing natural energy from the outside world, they nourished themselves in return. Under natural energy's subtle influence, they gained longevity, immense strength, and other abilities, but the process required an exceedingly long time.
Hyuga Yu went a step further, skipping the extremely lengthy process of natural energy subtly transforming the body.
