Next, the resistance of [Armorer Type I] to various ninjutsu was tested.
The results were still excellent.
The impact of offensive ninjutsu cast by a Chūnin on [Armorer Type I] was significantly reduced.
After all, the most notable trait of a ninja is high offense but low defense.
Even a Jōnin could be killed by a kunai to the heart if caught off guard without any defense.
But after putting on [Armorer Type I], ordinary kunai and shuriken could no longer cause harm.
As for ninjutsu—
Previously, you could only withstand one shot of the Great Fireball Technique, but now you could endure three, maybe even four.
And with the equipment enhancing mobility, your chances of being hit are also greatly reduced.
Unlike Jiraiya, who still had concerns, all the Konoha shinobi present were visibly excited.
Come on, this thing boosts defense and agility at the same time?
Just imagine: a squad of ninjas wearing armor charging right into the enemy lines—what could stop them?
Unless the enemy deploys Jōnin-level forces, a few Chūnin working together wouldn't be able to take down even one Konoha shinobi equipped with [Armorer Type I].
This result shocked nearly everyone present.
It really felt like the entire ninja world was about to change.
After the test, Might Guy reluctantly removed his beloved gear.
But the shock Simu was about to bring didn't stop there.
After solving the hardest problem—the fusion of chakra and natural energy—his various inventions began pouring out like a flood.
"In addition to Armor One, I've also developed a suit called [Spellcaster Type I]," Simu announced.
[Spellcaster Type I] looked very different from [Armorer Type I].
The latter focused on full-body protection.
The former, however, was designed purely for offense.
It featured only a core reactor embedded in the chest—everything else was a thin layer of cloth.
But etched into the fabric were intricate patterns.
These patterns were designed by Simu, based on intel from the Hyūga clan and his own observations.
The underlying principle was to imitate the key chakra pathways in the human body to enhance chakra flow.
This equipment offered no significant defense—but it did boost speed, and more importantly...
It greatly increased the power of ninjutsu.
In simple terms: it could convert any ninjutsu you used into senjutsu!
This statement left all the shinobi present completely stunned.
Thanks to Simu's previous explanation, many of the Jōnin already had a basic understanding of senjutsu.
But the threshold to learn it was ridiculously high—even among the Three Great Holy Lands, it was considered a core, sacred technique.
They had always wanted to learn, but didn't know where to even begin.
And now, Lord Hokage was telling them that this suit could convert their regular ninjutsu into senjutsu?
How could they not be excited?
Seeing their reactions, Simu called over one of his disciples.
"Obito, go give it a try."
"Leave it to me!"
Obito was already wearing the [Spellcaster Type I] armor.
As soon as Simu gave the command, he stepped into the test zone.
The reactor embedded in the chest lit up instantly.
The fabric didn't restrict Obito's movement at all.
He could even wear a standard shinobi vest over it without a problem.
He quickly formed a series of hand seals. Natural energy and chakra fused together, creating senjutsu chakra, which was concentrated in his mouth before release.
"Senjutsu: Great Fireball Technique!"
A raging inferno burst from Obito's mouth, forming a massive fireball.
With the boost from natural energy, the size of this fireball was nearly three times that of a standard Great Fireball Technique!
In other words, [Spellcaster Type I] had tripled the power of Obito's ninjutsu!
The brilliant orange flames illuminated everyone's faces—
—along with the ambitions burning in their hearts.
With such heaven-defying equipment, what did Konoha have to fear?
The fireball scorched a massive black crater into the training field—
—but everyone's hearts were blazing with excitement.
Even Jiraiya was visibly shaken.
What Obito had just used was indeed a proper senjutsu technique.
But true Sage Mode would increase a person's ninjutsu by far more than that.
"This device is currently utilizing only about 20% of the available natural energy. There's still a lot of room for improvement," Simu said calmly, hands in his pockets.
As someone who had trained in Sage Mode himself, he could clearly see the flaws in [Spellcaster Type I].
Still, as upgrades continued, this equipment would get closer and closer to real Sage Mode.
Even at only 20%, the improvement in ninjutsu output was astonishing.
Enough to make Konoha's shinobi much stronger in battle!
"Next up is live combat testing. I'll leave it to you, Jiraiya-sensei."
Simu smiled confidently.
After witnessing the terrifying power displayed by the ninja, Jiraiya finally showed no contempt this time.
Kakashi also wore the [Spellcaster Type I] armor.
He stood opposite Jiraiya.
Kakashi imitated his master and pressed his hands to his chest.
The lines on his body instantly lit up, and a blue chakra aura surrounded him.
This whole process lasted less than a second.
Kakashi slowly opened his eyes.
The next moment, Kakashi vanished from Jiraiya's sight.
Dazzling lightning illuminated the entire battlefield.
Jiraiya's heart trembled; her hands quickly formed a mudra, and the silver hair on her head instantly wrapped around her like armor.
A swift lightning bolt appeared in front of her in an instant.
Raikiri already had increased speed, but after being enhanced by [Spellcaster Type I] and combined with Kakashi's mastery, the speed reached a level ordinary ninjas could never reach.
The tough silver hair ball was slashed by Kakashi's enhanced Raikiri.
Silver, wire-like strands scattered in all directions.
Lightning sizzled in the air.
Faced with Kakashi's fierce attack, Jiraiya braced herself.
"Fire Style: Great Flame Bomb!"
A large amount of toad oil spat out by Jiraiya ignited into a terrifying sea of flames.
Facing such a powerful offense, Kakashi's expression remained calm.
"Spellcasting Enhancement: Water Style Waterfall Technique!"
Pressing his hands to the ground, raging water gushed out violently, fiercely colliding with the oncoming sea of flames.
The intense heat instantly evaporated the water into white steam.
But Kakashi's Water Style ninjutsu successfully blocked Jiraiya's attack.
Amid the swirling white mist, it sounded as if tens of thousands of birds were singing.
...seeking flowers...
Piercing thunder cut through everything and reappeared in front of Jiraiya.
"Spellcasting Enhancement: Triple Raikiri!"
Three Kakashi clones appeared simultaneously beside Jiraiya.
The three immortal Raikiri struck at Jiraiya at once.
Jiraiya, a veteran of countless battles, didn't expect Kakashi to move so fast.
Unable to react, she was slashed into several pieces.
Seeing this, Kakashi's eyes darkened.
Sure enough, Jiraiya's body turned into white smoke.
Then the ground beneath them suddenly sank.
Countless silts swallowed them until the three Kakashi clones dissipated into smoke.
"Did you really use three clones all at once?"
Jiraiya was surprised.
When did this brat gather so much chakra?
Kakashi descended from the sky.
Jiraiya was alone below.
"Spellcasting Enhancement: Lightning Style—God's Punishment!"
Lightning flashed across the sky.
A terrifying thunderbolt instantly fell from above, striking Jiraiya's body directly.
Such power was likely an S-rank ninjutsu!
Lightning engulfed everything.
The entire training ground was reduced to ruins.
"Jiraiya-san, is she...?"
Minato was amazed by Kakashi's terrifying power.
Then he worried whether Jiraiya was injured by the attack.
"Don't worry, she's fine."
Simu smiled, a trace of joy on his face.
Cough, cough, cough...
As the smoke cleared, Jiraiya appeared, her hair disheveled and a little messy.
At this moment, red markings appeared on her face, along with some toad-like features.
"I didn't expect to be beaten by a brat and forced to use Sage Mode. What a shame."
Jiraiya stood up.
She seemed fine.
Only her hair was slightly burnt.
Kakashi then deactivated [Spellcaster Type I].
This test was only to demonstrate the power of the ninja tools created by Simu.
Winning or losing didn't matter.
But looking at the result—
Jiraiya, one of Konoha's Sannin, was pushed to use Sage Mode.
Even if it was partly due to Jiraiya's own stubbornness as an old-timer, it still proved the power of this equipment.
All the Jōnin present respected Simu even more.
Not only was he powerful himself, but he also created various ninja tools that greatly enhanced Konoha's combat strength.
Where else could you find a Hokage like this?
Compared to the Second Hokage, who mainly developed ninjutsu, Simu's influence was growing invisibly but steadily.
Back in the Hokage's office, Lu Jiu asked:
"What do you plan to do with these tools? Will they be deployed on a large scale?"
Lu Jiu was also stunned by the terrifying power displayed by these ninja tools.
Not to mention a full deployment, even with only 2,000 equipped ninja, Konoha's forces could completely crush any great nation!
Simu smiled and said:
"Don't worry, let's test the waters over there first."
"There?"
Lu Jiu suddenly realized.
The "over there" Simu mentioned was, of course, the Revolutionary Army hidden in the shadows...
