Thinking carefully, Ash took out the slate from his storage ring once again and placed it between the three sacred implements.
The tomoe of his Kaleidoscope Sharingan spun rapidly, and a vast surge of mental energy burst forth. The slate began to glow, and its inscriptions shifted as if unveiling hidden truths.
He realized then—the slate's original spiritual power was not just concealing its contents, but also suppressing the three sealing implements behind it.
Without this suppression, the super ancient Legendary Pokémon sealed within would have already broken free.
As Ash poured his mental energy into the slate, the golden aura enveloping the three implements weakened. Eventually, the glow was so faint it could barely be seen.
"Damn it… my mental strength isn't enough. I can only hold down these seals temporarily."
Ash's face twisted with frustration.
"Back then, I didn't even think of this possibility. And yet, the system's earlier explanation feels… off."
He clenched his fists.
"It only takes a thousand attribute points to erase the mental energy on the slate? That didn't make sense from the start. Sure, boosting mental power is costly, but just breaking spiritual energy with no offensive force shouldn't cost that much!"
Exhausted, Ash leaned against the cavern wall, pale from the effort. He hadn't expected his mental power—already boosted twice back in Shenlong Cave—to still be insufficient. The irony stung.
"System, calculate how long the mental power I've just infused can suppress the three implements." His voice was strained, sweat dripping down his forehead.
Ding~!
[According to current estimations, with the host's mental strength, suppression will only last for seven hours.]
Ash's eyes darkened.
"What? This slate's seal supposedly lasted thousands of years before weakening. Why hasn't it eroded? And if you knew its purpose, why didn't you tell me earlier?"
Ding~!
[The spiritual power on the slate has indeed weakened—dramatically. Had it retained its original strength, the host would not have been able to approach at all. In the ultra-ancient era, this place was revered as a sacred altar. The slate's energy was so overwhelming that even those who created it, superpowered humans who infused their combined will, could not endure being near it.
Additionally, as a reminder: this system functions only as an auxiliary support. Unless required, it will not provide unsolicited information. Previously, the host only asked how many attribute points were needed to erase the slate's power—not its full purpose.]
Ash muttered a curse under his breath. He already knew the truth—the system was nothing more than a programmed tool. It had no will of its own. Unless his life was directly at risk, it would not act on its own initiative.
"…System, how many attribute points would it take to completely suppress the three seals?"
Ding~!
[Complete suppression requires 10,000 attribute points.]
Ash's jaw dropped.
"What the hell!? That's ten times more than before!" His face twisted in anger. He only had four thousand points left—nowhere near enough.
But then a thought struck him. His eyes widened.
"Wait… my Mangekyō isn't just any version—it's modeled after Uchiha Itachi's. That means my Susanoo should wield both the Totsuka Blade and the Yata Mirror…"
He recalled the legends: Itachi's Susanoo carried the Totsuka Blade, a sealing sword ranked even above the fabled Grass Cutter Sword, and the Yata Mirror, a shield said to repel all attacks.
"There are three Grass Cutter blades in the Naruto world—the strongest being the Totsuka Blade itself. The others are in Orochimaru's possession… but if I manifest Susanoo here, will my Totsuka truly have the same sealing power?"
"System, answer me—can my Susanoo's Totsuka Blade seal these three super ancient Legendary Pokémon? And can the Yata Mirror really repel any attack?"
Ding~!
[The Totsuka Blade is a sealing weapon. Once it strikes, it can seal according to the host's intent, with a maximum of three seals.
The Yata Mirror is a defensive divine treasure capable of blocking and even reflecting all attacks. However, the stronger the attack, the greater the mental energy consumed.]
"Fortunately, there are only three of them… This time I really got lucky. For a moment, I thought I was done for."
After hearing the system's explanation, Ash finally let out a breath of relief. The threat was limited to just three super ancient Legendary Pokémon—nothing more.
Earlier, he had panicked and recklessly poured his mental energy directly into the stone slab.
But even if those three Legendary Pokémon were released, he reminded himself that there was no need to lose composure.
With his strength—already comparable to a second-tier Legendary—and with both Dragonite and Suicune at his side, he still had a fighting chance.
The Yata Mirror, while capable of deflecting and resisting all attacks, consumed an equal proportion of his mental energy in return. It wasn't the most practical weapon for prolonged use. Still, in a desperate, life-threatening situation, it could prove invaluable—if he had enough mental reserves to wield it.
Now that he understood the Totsuka Blade's ability to seal, Ash's worries eased. He sat down cross-legged, closed his eyes, and entered meditation, focusing on restoring his depleted mental strength.
Time passed, and as his energy slowly recovered, the faint glow of the three seals brightened again, becoming more stable than before.
Five hours later, Ash opened his eyes. He stretched, rolled his shoulders, and twisted his neck, the joints cracking audibly in the quiet cavern.
