Deep in Might Guy's heart…
He'd always awaited a chance.
A chance, like his father, to unleash his full youth.
That's why he relentlessly trained in the Eight Gates.
This forbidden technique traded life for fleeting power, demanding grueling effort to master, yet it was a true miracle, letting the user surpass their limits.
So, he refused to dwell on time or limits.
As long as he lived…
His limits could always be surpassed.
And after surpassing them… well, he'd be dead anyway.
Shen Mo heard Might Guy's inner resolve.
"Ignoring what can't be changed, ready to burn everything—you've got the makings of true will," Shen Mo said, almost wistful, then smirked. "But now, you can seriously consider limits and time. With cans, those aren't unchangeable."
His words made Might Guy's eyes widen.
Then it clicked.
These were cans!
Everyone saw Hiruzen Sarutobi growing younger. If lifespan wasn't an issue, time and limits could be broken too!
"After all that, what's this item?" Tsunade stared at the crystalline pill, unable to discern it.
No special aura, no notable power.
"The two familiar people I mentioned," Shen Mo smiled. "Their names: Extreme Martial Emperor and Nen Emperor."
Yes, the advanced class-changes of male fighters from Dungeon & Fighter (DNF).
The Extreme Martial Emperor, breaking limits.
The Nen Emperor, transcending time.
Originally separate branches, Shen Mo merged them.
"Extreme Martial Emperor," Might Guy murmured.
"Sounds like a title," Hiruzen Sarutobi interjected.
"Exactly, a title," Shen Mo nodded. "The Extreme Martial Emperor reached his peak, then abandoned his throne and glory, pushing forward with sheer will to break his limits. His secret lies within."
That was the Extreme Martial Emperor's lore.
This pill's effect: shattering bodily shackles, resetting to a new growth phase.
In other words…
Adult Might Guy would revert to a youthful state, with greater potential for training.
"And the Nen Emperor?" Tsunade pressed.
"Him?" Shen Mo recalled the Nen Emperor's image, chuckling. "A free-spirited man wielding Nen energy, facing time as his foe. Through Nen's wonders and his grasp of life and death, he transcended mortality."
These powers combined formed Shen Mo's gift to Might Guy.
In short…
Breaking physical limits, plus qigong.
"Nen…" Might Guy thought of his student Neji, asking, "Like Neji's?"
"Similar concept, different worlds, slight differences," Shen Mo shook his head, explaining. "Nen, qi, or qigong exists in many worlds. Neji's Nen is more versatile, while yours focuses on flow."
Dragon Ball's ki prioritized raw destructive power.
No need for much technique.
Just faster speed, stronger force, tougher body!
In that world, ki and physical strength were one.
Hunter x Hunter's Nen was broader, enhancing weapons, controlling, manifesting, or projecting, seemingly limitless.
Both suited Might Guy, yet neither was perfect.
So, Shen Mo crafted a hybrid qi.
It had combat utility but required constant physical training and technique to shine.
"I don't fully get it, but eating this gives me a shot at breaking limits and time, right?" Might Guy grabbed the pill and, before Shen Mo could reply, swallowed it.
"Guy!" Tsunade's face shifted. "It could be dangerous!"
Having seen Neji's class-change, she knew they could carry risks.
They'd been told!
Be cautious, understand first.
"I know," Might Guy flashed his thumb, grinning brightly. "But youth fears nothing."
"It's fine," Shen Mo said. "This pill's class-change has no danger and is guaranteed to succeed. How much you achieve depends on you. Even the limited cans that follow are mostly supplementary."
Though that support was essential.
Shen Mo thought to himself.
Might Guy wanted passionate training? Shen Mo would oblige, but the money still had to flow.
Can training items and methods would boost efficiency and breakthroughs.
Whether that beat instant power…
Depended on the person.
Might Guy felt a heat surge through his body. His bones creaked, muscles ached, but soon, a warm current rose within.
Finally…
He felt lighter.
As if a long-held shackle had been released.
"Is this the class-change feeling?" Might Guy clenched his fists, brimming with excitement. "I feel ten years younger! Let's try fifty laps around Konoha—no, I could do five hundred!"
As a taijutsu ninja, he knew his body best.
His strength hadn't dropped.
Yet he felt back in his growth phase.
As for the Nen qi…
He ignored it for now.
He just wanted to train his body like crazy!
To relish growing stronger through effort!
"Running alone, even for a hundred years, won't hit your current limits," Shen Mo shook his head, glancing at the remaining funds. "You've got enough for nine Extreme Martial Emperor Series limited cans. I suggest buying them first. Without them, your growth will be slow."
