Root Headquarters —
In the dimly lit underground base, Danzo Shimura was livid. The Root headquarters, once coldly efficient, now looked like a war zone. In a fit of rage, Danzo had smashed desks, overturned shelves, and obliterated equipment. In mere minutes, the solemn facility was reduced to wreckage.
Still fuming, Danzo paced furiously, his fingers twitching at his sides. Then, in a rare moment of frustration, he stood still — trembling like a furious little dog, legs quivering, glaring at the cracked wall ahead.
"Damn you… Sarutobi Hiruzen… and Tsunade!!"
The cracked wall bore silent witness to his fury. Finally, Danzo inhaled sharply, calming himself.
"Report!"
A Root shinobi appeared silently behind him. "Yes, Danzo-sama."
"Have you located Yakushi Nono?"
"We've traced her to the inner sector of the Senju compound."
Root's intelligence network remained formidable.
"Senju compound…" Danzo narrowed his eyes, suppressing his killing intent. Though he had dared to move against the Uchiha, he hesitated when it came to the waning but still-symbolic Senju Clan.
A single misstep can destroy everything.
Danzo clenched his fists. "Uchiha Fenghuo… what game are you playing?!"
Three days after he'd ordered the quiet elimination of the young Uchiha Fenghuo, Tsunade had intervened and taken Nono away. Danzo didn't believe in coincidences — not in this village.
And Hiruzen's reaction since then? Suspiciously measured. Is the timing off? Could a move against Fenghuo jeopardize my long-term plan…?
Hokage Tower —
When Hiruzen Sarutobi summoned Fenghuo, the boy hadn't expected to hear Tsunade had already moved Yakushi Nono to safety.
"Thank you, Tsunade-sama!" Fenghuo bowed gratefully.
Tsunade waved it off. "Don't thank me. Just remember your promise," she said coolly before walking off.
"Sister Yakushi… is she okay?" Fenghuo asked, chasing after her with his eyes.
"She's safe," Tsunade's voice called from beyond the door. "But you won't be seeing her for a while."
Still acting like a tsundere, Fenghuo thought, amused and touched by her blunt compassion.
Hiruzen exhaled smoke from his pipe and fixed Fenghuo with a serious look.
"Fenghuo… how much do you know about Root?"
Fenghuo tensed. He pushed down his emotions and answered, "Sister Nono only said it was Danzo-sama's covert division under the ANBU."
Hiruzen nodded. "It's not an easy truth for someone your age… but one day, you'll understand. No matter how deep the darkness, Konoha is still your home."
Fenghuo nodded solemnly.
"I'll handle Danzo. But stay alert. He won't give up so easily," Hiruzen warned.
"Yes, Hokage-sama."
The Third Hokage leaned back, eyes misty. "Danzo and I… we were both disciples of the Second Hokage, alongside Homura and Koharu. Back then…"
As Hiruzen drifted into reminiscence, Fenghuo took it as his cue to leave.
If he starts from the Warring States Period next, I won't make it out of here until tomorrow morning…
Outside, the sun shone brightly. Fenghuo felt the tension release from his shoulders. Even his chakra seemed to flow more freely.
The Next Morning —
"Ugly—Mao—Shen!"
"Lightning Style: Chidori!"
A torrent of chakra surged into Fenghuo's right hand, concentrating into crackling white lightning. The chirping noise was deafening — like a thousand birds screaming in his ear.
Fenghuo marveled at the power coursing through his hand. A single motion felt like it could pierce the air itself.
He quickly suppressed the technique and sprinted toward Hokage Rock.
In the forest clearing where he'd trained with Might Dai, Fenghuo activated Chidori again.
"Lightning Style: Chidori!"
Chirpchirpchirp…
Power surged forward, and he charged. Trees, rocks, and earth tore apart in his path. Nothing stood against it.
Boom! Crash!
Chidori ripped through everything like a hot blade through paper.
"Again!"
His chakra reserves were still sufficient, and he tested it repeatedly.
After a dozen runs, Fenghuo stood catching his breath, analyzing the jutsu.
It's fast and powerful, but the path is linear. It lacks flexibility… no wonder Kakashi had to refine it into Raikiri.
Raikiri was an S-rank jutsu — still far from Fenghuo's current reach.
"Eight Gates, Rasengan, Chidori…"
He'd come far in both taijutsu and ninjutsu. Only genjutsu remained underdeveloped, but he planned to study under Kurenai's father, Yuhi Shinku, soon.
Maybe I should ask Minato-sensei to teach me sealing next?
Was it greedy? Perhaps. But he had shadow clones.
With a smirk, Fenghuo created a clone and sent it to Minato while his real body continued taijutsu training.
Forest Clearing —
Bang! Bang! Bang!
Before a massive tree stump, Fenghuo stood in a horse stance, fists hammering forward with precision. Each strike landed with a meaty thud. His knuckles split. Blood smeared across the wood.
"One hundred… one hundred and two… two hundred… five hundred and twenty-eight!"
He panted, shirt drenched in sweat, muscles burning. Numbness crept into his hands.
"Haa… haa…"
Gathering chakra, he activated the Mystic Palm Technique. The pain faded gradually as chakra sped up recovery.
In five minutes, the open wounds sealed themselves.
"Next: side kicks!"
Thwack! Thwack!
Left leg, again and again. "Twenty-eight… one hundred and seven… three hundred and twenty!"
Meanwhile, at Minato's Residence —
"You sent a clone! Just a clone!" Kushina Uzumaki's hair lifted with fury, crackling with chakra. "That's so rude!"
Minato hurriedly held her back with a nervous smile.
Fenghuo's clone scratched his head sheepishly. "Sorry! My main body is in the middle of intense physical training…"
Minato smiled warmly. "Don't worry, Kushina. He's working hard."
Kushina pouted, slightly appeased.
Minato already knew about Fenghuo — not from official records alone, but through his own observation. He was impressed not just by the boy's drive, but by the fact that he had independently begun developing the Rasengan.
At first, Minato thought it was a coincidence. But when he saw Fenghuo truly master the Spiral Sphere, he realized: this technique had limitless potential.
It was untyped — a pure chakra form, like a blank canvas. Shape transformation, nature transformation — anything could be layered onto it. In the right hands, it could evolve into a dozen or more S-rank jutsu.
And Fenghuo had shared it with him without hesitation.
Minato respected that kind of trust.
…Though if he ever learns that I'm actually the original creator of Rasengan… well… heh.
