"Sir… are you still going?"
Support from guards, Mui limped onto the castle's central plaza, leaning on a cane, his chest wrapped in thick bandages. He watched Karin, who sat swinging her legs, bored, and asked.
Karin propped her chin on her hands, sighing in boredom, "Uncle Mui, he's still fighting."
"Good." Mui nodded, then instructed his guards: "Prepare dinner for the young lady."
"Yes, sir!"
Scattered sounds of pounding and crashes reverberated throughout Hozuki Castle. It had been three days since the Purest Bliss Box was activated.
Naruto—ever since discovering Go's regenerative ability and how the box worked—had been attacking relentlessly. It wasn't a battle; it was a one-sided beatdown.
Go stood no chance: Naruto outclassed him in strength, speed, and special techniques. Each hit sent Go crashing down, emerging injured but still alive. Then another crush. Rinse and repeat.
Suddenly, a sharp whistling tore through the sky. A flaming red rock hurtled downward and slammed into the castle grounds—DUANG
Another crater carved into Hozuki Castle. The landscape looked like a lunar surface.
"What a satisfying fight," Naruto's voice drifted down as he glided toward the crater. "No wonder Master Kakarot said you only grow stronger in a real fight."
"Brother Naruto!" Karin jumped up in delight.
Naruto nodded, approaching Go's crater. "Don't play dead. With your healing ability, this wound's nothing. Let's go again!"
"Roar!" Go howled and erupted in dark energy—he'd entered berserk mode.
"Here it comes!" Naruto readied himself, coiling his foot.
Go didn't wait—he turned and fled.
Smart move… running from the ring leader? Naruto's foot thunked off the ground and he surged forward. "Stop!"
As if! Go's speed surged with the desperation of three days' unending punishment. He finally tapped into survival instinct, matching Naruto's pace, and dove into the Purest Bliss Box—whoosh
The massive door slammed shut behind him, the others also snapping shut as if sealing out any intruder.
Naruto pounded on the box's shell. His slap shook the entire structure—no, the whole castle quivered. Wuwei's eyes twitched.
What… is this thing? More creature than machine.
Naruto teased, "Mr. Mui, backtalking is rude."
Mui froze, caught off guard. Meanwhile, no matter how Naruto smacked the box, it remained unmoving: no glow, no rumble, just a regular ugly cube.
Want me to break it open? Naruto decided to really test it. He clenched his chakra and punched the box with full force—DANG!
The soundwave knocked everyone's ears into ringing. A fine crack traced across the surface—one crack—unheard of after a millennia of use.
Hum! Red light pulsed. Dark energy seeped across its panels. The entire box vibrated.
"Not impressed?" Naruto grinned and took his stance—ready for another blow.
Vuuummmm! The box quaked again. The glow flickered in chaotic red.
"Okay, okay—I'm joking," Naruto waved off, stepping back.
It seemed the box had responded—acknowledging Naruto, recognizing him. It submitted—but demanded no more physical abuse.
Legend holds the Purest Bliss Box is sentient. It can be activated, but only truly wielded by someone it trusts. Wuwei's chakra feed could only trigger it—it couldn't control it.
Now the box accepted Naruto on a physical level.
And legendary wisdom is false: the box can't grant wishes. It was built as a weapon of destruction. Its only use: to destroy.
With Go's resilience, mind-reading (ironically), and the box's massive, life-absorbing power, he once ranked as the Six Paths' ultimate weapon. Now, the box pledged full summoning support: whenever Naruto needed it, he could summon the box—and it could release Go to fight.
Naruto chuckled softly. "That's too much waste—this is an elite training tool!"
Go was indestructible, could tank hits—perfect.
Naruto stroked the "joy" panel on the box. With resolve he whispered:
"Purest Bliss Box, I want you to help my training."
The box trembled in response—its agreement.
"Ha ha ha," Kurama's voice echoed delightedly inside Naruto's mind: "Another one driven mad."
Naruto glanced sideways, amused, but then frowned: "Wait—why 'another'?"
