The Training Room.
Uchiha Xuantou sat cross-legged, his entire body enveloped in a faint red glow.
A more fundamental, more primal evolutionary energy dwelled within him, surging from his heart into every limb and bone, advancing toward a higher level.
Evolution!
Evolution!!!
Every meridian and every cell in his body cheered and rejoiced.
His body, honed through years of taijutsu training, was ravenous, wildly competing for this energy.

Ring after ring, layer after layer, seemingly without end.
As soon as the patterns covered his skin, Xuandou's body gradually
