Time flows back.
"Wood Style: Deep Forest Emergence!"
As Kaguya entered Infinite Tsukuyomi, Madara clapped his hands. Thick tree trunks erupted all over the world, extending branches covered in leaves to wrap up those caught in the Infinite Tsukuyomi. Only the few surrounded by Sasuke, and those under Edo Tensei were immune to the genjutsu. There was also Obito, encased by Black Zetsu.
Just as Madara was about to deal with Naruto and Sasuke, Black Zetsu, from behind Madara, thrust a hand into his chest. Madara’s body rapidly expanded, his hair growing wildly as the chakra of those engulfed by Infinite Tsukuyomi was absorbed, save for Lixing.
Before long, Madara transformed into Kaguya Otsutsuki. Black Zetsu then revealed the truth, admitting to altering the stone tablet. Even Hagoromo, the Sage of Six Paths, had failed to notice his existence; his sole purpose was to revive Kaguya.
Kaguya opened her Rinne Sharingan and transported everyone present to the Amenominaka dimension, beginning with a world of flames.
Here, Naruto and Sasuke conspired to use the Reverse Harem Jutsu to distract Kaguya, intending to seal her. However, Kaguya reacted swiftly, instantly transporting them to a world of ice and snow.
Naruto and Sasuke were instantly frozen, while Kaguya used Yomatsukami to escape the ice.
Fortunately, Sasuke shattered the ice with Amaterasu, casting it upon Kaguya. But Kaguya was immortal, and sealing was the only recourse.
At this point, Black Zetsu suggested separating them to defeat them one by one, thus preventing any sealing.
Kaguya complied, throwing Sasuke into a desert dimension, leaving Naruto alone.
However, Obito awoke and deduced Kaguya's ability was space-time ninjutsu. If they could find a way into that dimension, there was a chance to bring Sasuke back.
The group devised a plan, transmitting it to Naruto via shadow clones. Naruto cooperated, feigning capture by Kaguya’s ice. As Kaguya approached, he unleashed a powerful taijutsu attack. Kaguya countered with Shinra Tensei, blasting Naruto away.
Kaguya used Yomatsukami again. Seizing the opportunity, Obito used Kamui, taking Sakura and Naruto's clone into the dimension.
Black Zetsu, however, witnessed this. Upon realizing they had been discovered, Naruto's shadow clone chose to sacrifice himself, while Obito and Sakura hid within Kamui's space.
Kaguya and Black Zetsu believed the Naruto before them was the true body. Black Zetsu advised killing him directly, foregoing the small amount of chakra, to avoid further complications.
Kaguya fired several Gudodama, striking Naruto's shadow clone, which then turned to ash.
After dealing with Naruto, Kaguya returned to the ice world, only to find thousands of Narutos waiting. Black Zetsu realized he had been tricked.
Naruto placed the Truth-Seeking Ball behind his shadow clones, using them to stall for time until Obito could retrieve Sasuke.
Black Zetsu instinctively shielded the Naruto with the Truth-Seeking Ball, instantly concluding he was the true body. Kaguya slew the shadow clones one by one, eventually binding Naruto with her hair and piercing him with a Gudodama.
However, this too was a shadow clone. Naruto had deliberately attached the Truth-Seeking Ball to it to buy time.
Meanwhile, Obito, borrowing Sakura's Hundred Healings chakra, continuously opened spatial portals within the dimension in search of Sasuke. He accidentally opened an acid sea dimension. To protect Obito, Sakura was injured by the acid. She then removed her vest and tore off her sleeve.
Finally, Obito opened the desert dimension. Sakura cried out for Sasuke, who immediately rushed towards them. Obito, struggling to maintain Kamui, at the last moment swapped positions with Sakura's vest using his Heavenly Handpower, allowing Sasuke to escape the dimension.
After a brief wait, Obito gathered his chakra and brought the three back to the ice world, arriving just in time to witness the scene of Naruto's shadow clone being pierced.
Seeing Sasuke, Black Zetsu was startled, then deceived again by Naruto's shadow clone, directly advising Kaguya to stop holding back and deal with both of them.
Kaguya transported them to a gravity dimension, where everyone, including herself, was pinned down by immense gravity.
...
Outside, Lixing slashed through the leaves encasing him, appearing beside several Hokage. The four Hokage, Kushina, Rin, and others were gathered around Madara's lower half, while the soul of the Sage of Six Paths floated in the air.
"Falling Sakura!"
Without hesitation, Lixing swung his blade, obliterating the Sage of Six Paths' soul. At that instant, Naruto and Sasuke's Yang and Yin power became permanent, and the so-called Six Paths power could no longer be reclaimed.
"Enough rambling. Who wants to hear your story? Indra, Ashura, and the reincarnation. In all these years, only two reincarnators? This is breaking the established lore!" Lixing mentally grumbled about the plot.
The remaining resurrected individuals looked bewildered. The Sage of Six Paths' soul had been eliminated by Lixing. How had Lixing broken free from Infinite Tsukuyomi?
"Stop! I know you have questions, but I don't have time to waste. Here, use reverse summoning when day breaks to bring Naruto and the others back." Lixing threw a talisman to Hashirama, containing the life force of several individuals, the chakra of the Tailed Beasts, and some of Lixing's own chakra, sufficient for summoning them back.
"Yomatsukami!"
Lixing opened a portal, closed his eyes, sensing Kaguya's dimension, and stepped through.
The next second, Lixing materialized in the gravity dimension. However, the situation was precarious. The moment he entered, he saw a Gudodama hurtling towards him.
"Lixing! How is this possible! Why haven't you become Mother's nourishment?" Black Zetsu exclaimed in shock. He had clearly seen Lixing fall under Infinite Tsukuyomi, yet here he was again. How had Lixing entered?
"Black Zetsu! Haven't we reached an agreement? I won't interfere, and I'll help you capture the Tailed Beasts. You let me have a glimpse of the Rabbit Goddess, ah, so this is Kaguya! She is indeed beautiful!" Lixing casually caught a Gudodama and crushed it with a gentle squeeze.
"Mother, this person ignored the gravity. Let's take him to the dimension and deal with him all at once!"
Kaguya again heeded Black Zetsu's advice. The next moment, everyone was transported to the dimension. Due to Lixing's intervention, Obito was not killed by the Gudodama, and Kakashi was saved by Obito's Kamui.
As Lixing was about to speak, he suddenly felt a force controlling him, compelling him to protect Kaguya and kill Naruto and Sasuke.
"This is... Kotamatsukami! Black Zetsu, you bastard! I originally didn't want to bother with you, but you dare use Kotamatsukami on me! So you took Danzo's eye!" Lixing instantly broke free from Kotamatsukami's control. Change his thoughts? Impossible. Let alone the dual souls, this Heavenly Dao alone was an insurmountable gulf for Black Zetsu.
"I thought I wouldn't need it, but it's being used on you. Impossible! How could you break through Kotamatsukami!" Black Zetsu, who had only been pleased for two seconds, was immediately put in his place by Lixing.
