If the gravity chamber was mass-produced, Konoha's ninja would transform. Not only taijutsu practitioners. Even ninjutsu users would gain more chakra from stronger cells.
Naruto wasn't exaggerating when he praised Director Farasu's work. The idea was his, yes, but without Farasu and the tech division, it would've remained a dream. That alone might earn Farasu a place in Konoha's history someday.
Guy was eager to train more, but the tech division was closed for the night. Forcing people to work overtime for training wasn't an option.
Later that night, Naruto found Tsunade in her office enjoying a drink.
He explained the gravity chamber in detail, emphasizing its potential to strengthen every ninja from the foundation upward.
Tsunade froze mid-drink, amber liquor trembling in her glass.
"The entire environment becomes heavier? Affecting every cell?"
Her eyes sharpened immediately.
"You tested it? It works?"
"All afternoon. I broke past my limit three times. Even Guy sensei wants to train there now." Naruto responded quickly.
"It's useful for everyone. With stronger cells, more refined chakra follows naturally."
Tsunade slammed her hand on the desk. Papers jumped.
"Hahaha!"
Her laughter burst like thunder in the quiet night.
"Good! Brilliant!"
She was practically glowing with excitement.
"If this really strengthens internal organs and cell activity, then a day inside equals ten or fifteen days of normal training!"
As a medical expert, she understood instantly.
This could revolutionize ninja training.
"Farasu, huh? That man deserves credit!"
She slapped the desk again. The poor table trembled like a survivor of war.
Table: Thank you for acknowledging my pain.
"Naruto, your idea is good. He made it real. This contribution will be recorded heavily. Konoha must build more. Immediately."
She stood, grabbed her sake bottle, then forgot to drink as her mind raced.
"Summon the research team. Assess production capacity. The gravity chamber needs to become a standard facility. This is more valuable than ten S-rank forbidden scrolls!"
Naruto could already imagine a future where the village evolved as one.
He could reserve private chambers as a high-ranking shinobi, but mass production would take time. For now, he and Guy had access to the prototype.
They trained under it relentlessly, using Yang Release afterward to heal micro-damage. They ate large prey summoned by shadow clones from the forest.
Konoha's forests were abundant. Prey was no problem.
When Naruto and Guy rested, Sasuke, Hinata, and Kakashi used the chamber. Even the Third Hokage and Tsunade occasionally trained inside.
Nobody rejected growth.
Konoha's upper-tier combat power soared rapidly.
Meanwhile, Jiraiya departed again.
He planned to infiltrate the Hidden Rain and investigate Nagato's Rinnegan.
Naruto handed him a Flying Thunder God kunai.
"In case you're in danger. I'll come to you instantly."
With Jiraiya's strength, few could kill him in one strike. Naruto would reinforce him the moment needed.
He needed to train harder. He wanted to someday crush the Ten-Tails with his bare hands.
Far away, under endless rain, Jiraiya infiltrated Ame.
The village rarely saw sunlight. Steel pipes and dark buildings formed its core. Mist and dripping water carried a suffocating heaviness.
But the moment Jiraiya entered with his toad technique, he was sensed.
The rain itself was Nagato's sensory technique, similar to how Naruto used wind.
This time, Jiraiya was caught the same way Naruto once sensed intruders.
Pain stood beneath the rain, noticing a disturbance.
"Someone just blocked my rain. A strong chakra signature."
Konan nodded.
"I'll search."
Nagato halted the rain and reversed the technique, forcing the natural rain to cease entirely.
"Now. Go."
Konan scattered into paper butterflies, fluttering through the city like silent scouts.
Elsewhere, Jiraiya captured two Ame shinobi, demanding information about what had changed since he last visited.
