The Adamantium box expanded with the Undetectable Extension Charm was indeed good, essentially giving him his own Small World.
However, its drawbacks were equally obvious: it wasn't convenient to carry, and if it were stolen, everything inside would become someone else's.
He had actually thought about improving it, changing the box into something like a bracelet or a ring, similar to the spatial treasures in mythological legends.
But in reality, they were fundamentally different things.
The principle of the Undetectable Extension Charm is to expand existing space, and physical objects like bracelets and rings have no space within them to begin with, so how could space be expanded?
Even if a small space could be dug out inside, the difficulty would be immense, making it impossible to enter.
If it were truly possible to create spatial equipment using rings, bracelets, or similar items, then Newt, who was proficient in the Undetectable Extension Charm, wouldn't be using a suitcase that frequently needed to be checked.
But the Amenominaka of the Rinne Sharingan was different; those spaces were created by the Rinne Sharingan, akin to Small Worlds under different environments, just without life having been born yet.
He didn't need to carry anything; he could enter and forcibly bring others into them at any time, and he could also transfer everything from the Adamantium box into these spaces.
"Eighty Gods Vacant Attack!"
While Adam observed his surroundings, Ōtsutsuki Kaguya and Ōtsutsuki Isshiki also began to fight.
Ōtsutsuki Isshiki's strength was indeed formidable, but he was clearly still no match for Ōtsutsuki Kaguya; after only a few exchanges, he was severely wounded by her.
The Eighty Gods Vacant Attack, an ultimate taijutsu activated by the Rinne Sharingan, maximizes seven Chakra natures, releasing countless powerful fists capable of splitting mountains and cracking the earth.
Even Ōtsutsuki Isshiki's body could not withstand it.
"All-Killing Ash Bones!"
After severely wounding Ōtsutsuki Isshiki, Ōtsutsuki Kaguya raised her hand, and a bone spike shot towards Ōtsutsuki Isshiki.
This was no ordinary bone spike, but one activated by Bloodline Limit Expansion; once struck, the body would rapidly disintegrate into ash.
Even a perfect Susanoo activated by Yin Release could not withstand the power of the bone spike.
If Ōtsutsuki Isshiki were hit by the bone spike, he would surely die.
"Ki Blade!"
Just then, Adam, who had been watching from the side, finally made his move.
He couldn't let Ōtsutsuki Isshiki turn to ash; he still needed Ōtsutsuki Isshiki to make chakra pillss.
Which would prevail: the Ki Blade, capable of increasing combat power tenfold, equivalent to over twenty thousand, or the All-Killing Ash Bones of Bloodline Limit Expansion?
"Snap!"
The bone spike was immediately cut in half by the Ki Blade and fell to the ground.
Clearly, in terms of pure power, the Ki Blade was far superior.
The bone spike of the All-Killing Ash Bones primarily targeted the destruction of the body, rapidly turning the struck person's body into scattered ashes, but it was somewhat less effective against pure energy.
"I originally planned to deal with you after I finished him, but it seems you can't wait."
Seeing her attack interrupted, Ōtsutsuki Kaguya turned to look at Adam.
Black Zetsu, in her right hand, quickly warned her:
"Mother, be careful of this guy."
Having manipulated everyone, he alone couldn't see through Adam, this guy who had suddenly appeared.
He had been hiding his strength, and even now, Black Zetsu couldn't figure out his true power level; he had just blocked Mother's All-Killing Ash Bones.
His motives were even more unclear: one moment helping the Allied Shinobi Forces fight Obito and Madara, the next helping Madara acquire the Rinnegan to activate the Infinite Tsukuyomi, then fighting Ōtsutsuki Isshiki, and now saving Ōtsutsuki Isshiki.
It was utterly contradictory.
"His Chakra reserves are quite impressive. If I can absorb it, perhaps it can make up for the Chakra I once gave to my two children."
Ōtsutsuki Kaguya used her eyes to examine the Chakra within Adam, and her spirit was immediately shaken.
The amount of Chakra within Adam exceeded her imagination; although not as vast as the entire Ninja World's Chakra absorbed by the God Tree, it was definitely worthy of her attention.
Instead of the brutal approach she used against Ōtsutsuki Isshiki, she simply activated her ability, causing her hair to suddenly transform and coil towards Adam like snakes.
She wanted to capture Adam alive, then slowly absorb the delicious Chakra within him.
Facing the sky-filling white hair, Adam once again threw out a Ki Blade, and the white hair, infused with seven Chakra natures, was instantly severed by the Ki Blade.
"At this point, I won't waste any more time with you, Ōtsutsuki Kaguya. I know everything about you, and I deliberately held back to let Black Zetsu resurrect you.
I'll give you two choices: either submit to me, or I'll kill you!"
Ōtsutsuki Kaguya was said to have an Sage body.
Firstly, because the Ōtsutsuki Clan had no lifespan limitations.
Secondly, because the Ōtsutsuki Clan could replicate themselves and digitize their data, then parasitize others, with a black diamond mark appearing on the host's palm as a symbol.
This mark was the "Karma."
As long as the Karma remained, an Ōtsutsuki could be resurrected indefinitely.
Thirdly, Ōtsutsuki Kaguya had merged with the God Tree and eaten the god tree fruit; as the progenitor of Chakra in this World, even if her body were destroyed, her soul would be very difficult to completely kill.
As long as these conditions were met, she could be resurrected again.
But Adam could not only destroy Ōtsutsuki Kaguya's body but also, in Magic God Mode, repeatedly use the Curse of Slaying to slowly wear down Ōtsutsuki Kaguya's soul.
When Ōtsutsuki Kaguya's soul was completely worn away, she would naturally die.
Ōtsutsuki Kaguya naturally didn't take Adam's harsh words seriously, because she didn't believe anyone in this World could kill her.
So, as soon as Adam's words fell, she launched her attack.
"Eighty Gods Vacant Attack!"
The ultimate taijutsu that had severely wounded Ōtsutsuki Isshiki reappeared, and countless dense Chakra fists hammered towards Adam.
"Great Ape Mode!"
Adam also stopped wasting time, directly merging his Ki with Chakra, stimulating his Saiyan bloodline, and transforming into a Saiyan Great Ape with over twenty thousand combat power.
Ōtsutsuki Kaguya's strength was not weak; if he wanted to end the battle quickly, he needed to use overwhelming power.
"Four-Tails?"
Seeing Adam suddenly transform into a Great Ape, everyone present was stunned.
However, they quickly realized it wasn't the Four-Tails; although it looked somewhat similar, one was a Chakra conglomerate, and the other was a physical being, so there was a significant difference.
Moreover, the Four-Tails was currently inside Ōtsutsuki Kaguya.
But in the next second, their mouths collectively dropped open again.
Because after Adam transformed into a Great Ape, facing the countless Chakra fists that had severely wounded Ōtsutsuki Isshiki, he didn't dodge or defend at all, relying on his body to endure them all.
"What, are you just tickling me?"
Adam patted himself, looking at Ōtsutsuki Kaguya with disdain and saying.
At this moment, Ōtsutsuki Kaguya also widened her eyes in disbelief.
