Buzz—Uchiha Obito narrowly avoided a sneak attack from behind by Uchiha Fugaku by timely phasing his body into intangibility.Swish—Failing to land a hit, Uchiha Fugaku quickly retreated with a flicker, widening the distance between them."My eye technique is absolute. You can't hurt me," Obito said casually as he slowly turned around.But in truth, he wasn't as calm as he appeared.It had been close—far too close.If he hadn't phased just in time, he might already be injured."There's no such thing as an invincible jutsu. Not even space-time techniques are truly without flaw," Fugaku replied coldly.He knew well that while Kamui's intangibility was near-invincible, it wasn't without limits.During the moments when Obito attacked or attempted to absorb an enemy into his space, he had to materialize.Fugaku had been extremely close just now. If Obito had been even a fraction of a second slower in activating Kamui, he would've been wounded."Then why don't you try again?" Obito sneered, flashing forward toward Fugaku.A metal chain appeared in his hands, one end gripped in each.Fugaku quickly slashed forward with a kunai—but it passed straight through Obito as if cutting air, the two crossing paths.At that exact moment, Obito re-materialized, and the now-solid chain whipped around, attempting to bind Fugaku.Swish—Fugaku used space-time movement to dodge, reappearing at Obito's left side and striking out with a kunai.But again, it only hit air—Obito had already phased in time."Still too slow."Fugaku retreated a step, a thoughtful look in his eyes.He had failed to hit Obito twice now—his speed just wasn't quite enough.To hurt Obito, he had to land an attack before Obito phased out. Which meant he needed to be faster.Swish—Obito attacked again."Wood Style: Cutting Sprigs Technique."He lunged forward with a sharp, spear-like wooden branch in hand.Swish—Before it could hit, Fugaku activated the Eight Gates."Sixth Gate of View—Open.""Seventh Gate of Wonder—Open."Blue steam surged from his body.In this state, his movement and attack speeds soared to terrifying levels.Without even using space-time movement, he closed the distance with a single flash, reappearing behind Obito.At close range, his speed in this state even surpassed teleportation—while teleportation was instantaneous in travel, it required startup time.Whizz—He stabbed fiercely at Obito's back with his kunai.Thunk—The blade pierced into Obito's body.But just before it could go deeper, Obito phased again, preventing further damage."You actually wounded me!"Obito quickly retreated, creating distance, his face darkened.He reached back and felt liquid.Looking at his hand, it was blood red.He was wounded.Despite possessing Kamui's intangibility, he had been the first to be injured in this battle with Fugaku."Your space-time technique may be powerful, but it's not flawless. You must materialize when attacking—that's your weakness," Fugaku said coldly, still wrapped in blue steam.Kamui's phasing may be close to invincible, but not truly so.The instant Obito attacked, he had to materialize.This window was impossibly brief—most couldn't exploit it.But within the True Illusion World, where Fugaku could fully unleash the Eight Gates, he could take advantage of it."Tch—"Obito let out a cold snort.He hadn't expected Kamui's weakness to be discovered so quickly.Even if the enemy couldn't hurt him while intangible, the threat level of Kamui had clearly dropped.Buzz—A black vortex appeared above Obito's head, and a rain of kunai poured down.Each kunai had an explosive tag tied to its hilt.They all ignited, flying toward Fugaku.Boom! Boom! Boom!Explosions erupted in waves.The forest was torn apart by the blast, and craters formed in the ground.But Fugaku was nowhere in sight.Before the kunai could hit, his body turned into a mist of glowing blue particles and vanished.When he reappeared, he was right next to Obito, slashing at him with a kunai.Thunk—Obito phased, but not before the blade grazed him, leaving a fresh wound.His expression darkened even further.Even while on guard, he had still been injured.Fugaku's power was proving a serious threat.Obito stopped attacking and stared coldly at Fugaku."The Eight Gates might enhance your speed, but you can't maintain that state for long.""Whereas my Kamui intangibility can last indefinitely. You'll be the first to collapse."When Madara left Konoha, he took with him not only many Uchiha secrets but also numerous techniques originally belonging to the village.Obito had never trained in the Eight Gates himself, but he had studied it. He knew its characteristics well.With the Seventh Gate open, Fugaku's body would be enduring extreme pain. Every second caused significant internal damage.There was no way he could maintain this state for long."Don't be so sure."Fugaku smirked.In the True Illusion World, he had infinite stamina—and any damage from forbidden techniques could be instantly repaired.In reality, he could maintain this state for an extended time.Swish—He rushed at Obito again.Boom! Boom! Boom!Punches and kicks rained down on Obito.Even though Obito was intangible, every blow forced him to remain phased, unable to rematerialize or counterattack.One minute passed—Fugaku showed no signs of exhaustion. Obito remained composed.Two minutes passed—still no sign of fatigue. Obito held his composure.Three minutes passed—Fugaku remained full of -energy, and the expression beneath Obito's spiral mask… was no longer calm.
