The battles between Ninja, in addition to direct power comparisons, also involve understanding intelligence and countering abilities.
Kakashi and the Konoha young strong ones' intelligence had long been thoroughly investigated by Zetsu.
Even Naruto's Sage Mode had been mostly collected when Jiraiya infiltrated Amegakure in a previous battle.
In contrast, Konan and Obito's Ninjutsu intelligence was rarely leaked, and neither of them used conventional Ninjutsu.
This gave them a natural advantage in combat, and both were very capable of sustaining and evading, which perfectly countered Ninja like Kakashi and Naruto, who needed to end battles quickly.
"Whoosh!"
Just as Obito had activated Kamui and half of Naruto's body was being absorbed, a kunai with a sonic boom shot from a distance, aimed directly at his heart.
The fundamental principle of the Kamui space-time Ninjutsu in his right eye is to absorb and release anything into and out of his unique Kamui dimension.
The phasing ability, which makes him seem untouchable when attacked, is actually because he temporarily transfers the attacked part of his body into the Kamui dimension, thereby avoiding damage.
However, this phasing time cannot exceed five minutes at once.
His ability to move himself and others through space is actually by transferring himself and the people he's carrying into the Kamui dimension, and then using the Kamui dimension as a transit point to go to their desired location.
But this kind of full entry into the Kamui dimension for transfer is much slower than phasing, and he cannot use phasing during the transfer, making him unable to dodge attacks.
His teacher, Fourth Hokage Minato, had seen this flaw and thus injured him back then.
So, when he saw the kunai approaching, he immediately stopped casting Kamui and retreated to dodge the kunai's attack.
But as the kunai struck the ground, a figure also teleported there—it was Adam, who had rushed over from Training Ground Zero.
"It's Teacher's Flying Thunder God Technique."
At a glance, Obito recognized the Ninjutsu Adam used to teleport, and at the same time, he recognized Adam.
"Wood Release: Cutting Sprigs Technique!"
Extending his right hand, countless sharp wooden spikes instantly erupted, aiming directly at Adam's vital points.
Half of his body consisted of White Zetsu cells transplanted by Uchiha Madara, allowing him to instantly unleash powerful Wood Release Ninjutsu without hand signs, which was perfect for ambushing Adam, who had just teleported.
He had used this Cutting Sprigs Technique to wipe out all the Hidden Mist Ninja who were pursuing Rin back then.
With so many wooden spikes, if even one pierced Adam's body, it could cause his Chakra to surge violently, tearing his body apart from the inside, making it an extremely destructive and brutal Ninjutsu.
He had no choice; facing Adam, whom he considered a terrifying individual whose strength might even rival Uchiha Madara, he dared not be careless in the slightest.
It's worth noting that when he was dealing with Naruto in Sage Mode earlier, to prevent Kakashi from noticing anything, he had only been toying with Naruto using a kunai combined with Kamui's ability, without releasing any other Ninjutsu at all.
"Petty trick!"
Facing the incoming wooden spikes, Adam didn't dodge at all; he simply raised his hand and pointed forward:
"Fiendfyre."
Blue flames surged out, directly incinerating the wooden spikes into ash, and then transforming into a large blue serpent that, with great sentience, followed the path of the wooden spikes and bit towards Obito's arm.
"This flame can actually rival Amaterasu!"
Feeling his right hand's cells rapidly necrotizing after being enveloped by the flames, Obito's pupils constricted, and he unhesitatingly tore off his entire right arm, severing the fire snake's further consumption.
The root of Wood Release in this World is the God Tree, not ordinary wood, so it naturally wouldn't be countered by normal Fire Release.
Therefore, if Adam had used a normal Fire Release Ninjutsu, the wooden spikes would not have been burned away; instead, they would have pierced through the flames and continued into Adam's body.
Unfortunately, that was not the case. The Fiendfyre Adam used was the demonic fire from the Wizard World, one of the strongest Black Magic.
Like the black flames of Amaterasu, it possesses the characteristic that once it sticks, it cannot be extinguished unless completely burned out, even in water.
Moreover, if controlled well enough, it can mimic various monsters to specifically hunt down enemies.
If Obito hadn't decisively torn off his right arm, he would likely have had to sacrifice a Sharingan and use Izanagi to save his life.
However, for Obito, tearing off his right hand was no big deal; after all, his entire right half was composed of White Zetsu cells, so he could just go back and attach a new one after tearing it off.
"Phew, that's great, you're finally here."
Seeing Adam appear, Naruto grinned and struggled to get up from the ground.
In fact, when he felt the Kyuubi disappear from his body earlier, he knew that Adam had already arrived in this World.
It's just that things were different now than before.
Previously, he and Adam would agree on a time, and once Adam arrived at Mount Myōboku, he would find a specific small toad, and then Naruto would summon that toad, bringing Adam along with it.
Now that Adam had learned the Flying Thunder God Technique, he no longer needed to agree on a time with Naruto, and upon arriving, he wouldn't go looking for that specific small toad; he could just use Flying Thunder God to come directly.
So, even if he knew Adam had arrived in this World, summoning would only bring forth that small toad, not Adam.
But he knew that as long as Adam came to Konoha, he would eventually come to help.
"Adam, Naruto!"
At this moment, Kakashi, along with Shikamaru, Sakura, and Hinata, also ran over.
Sakura immediately placed a slug on Naruto and began performing healing Ninjutsu on him.
It turned out that Konan, seeing Adam appear and severing one of Obito's arms in the blink of an eye, became flustered and neglected her defenses, allowing Kakashi to seize the opportunity to break through with his group.
"My apologies for being late. I just happened to run into Sasuke and Danzo in a deathmatch over there, so I lingered for a while."
After repelling Obito, Adam didn't continue to pursue but turned around and said with a smile.
To others, the extremely dangerous Obito and Konan posed no threat to him at all, so he naturally didn't take them seriously.
If he truly wanted to kill Obito, Obito wouldn't be able to escape even with Kamui.
Because compared to phasing, the process of entering the Kamui dimension for transfer is much slower; others might not be fast enough, but at such close range, Adam could definitely catch up.
He could twist off Obito's head when his body was halfway into the Kamui dimension.
As for Konan, there's even less to say.
She can fly, but Adam flies faster than her; she's immune to physical attacks, but Adam can counter her with Fiendfyre.
Her strongest technique, Paper Person of God, with six hundred billion exploding tags, requires prior setup, and that kind of large-scale damage would be difficult to break his defense, and he also has Flying Thunder God to dodge.
"Sasuke and Danzo in a deathmatch? What was the outcome when you left? Is Sasuke okay?"
Upon hearing news of Sasuke, Naruto and Sakura immediately became nervous.
In their recent battle with Obito, they both knew that Sasuke had also come to Konoha for revenge, but they hadn't seen him.
