[After Shiro fell into darkness, the consciousness of Otsutsuki Kinshiki, residing within the Kāma seal, fully awakened.]
[In order to rapidly gain more power, Shiro voluntarily allowed Kinshiki's consciousness to modify his body. This also sped up the process of Kinshiki assimilating with Shiro.]
[With Kinshiki's help, Shiro successfully absorbed the power of Sasuke and Sarada's eyes, evolving his own eyes into the Eternal Mangekyō Sharingan. And whenever he wished, it could evolve into the Rinnegan, although he forcefully suppressed it.]
[After adapting to his newly acquired eyes, two months had passed.]
[During this time, the insane Kawaki had successfully destroyed the Five Great Shinobi Villages and killed nearly half of the entire ninja world.]
[As Kawaki had stated, his goal was to end the era of ninjas, and he would not allow any ninja to exist in this world.]
[Faced with Kawaki's genocidal wrath, the surviving ninja forces from the ninja world formed a united army, intending to fight Kawaki to the death on the battlefield.]
[On the day of the final battle, Kawaki stood alone against hundreds of thousands of ninja forces. A cold sneer appeared on his face as he calmly walked toward the ninja army.]
[With each step Kawaki took, the ninja army took a collective step back.]
[Kawaki's contempt grew stronger.]
["What's wrong? Afraid to attack? Then let me be the one to make the first move."]
[With a powerful thrust of his legs, Kawaki shot forward like an arrow into the ninja forces.]
[Kawaki, with his overwhelming strength, tore through the ninja forces like a tiger among sheep, causing chaos, death, and screams in every direction.]
["From this day forward, ninjas will no longer exist, and the world will usher in a new era of peace!"]
[Kawaki stood proudly atop a throne made of corpses he had personally crafted, issuing a domineering declaration to the trembling and hesitant ninja forces below him.]
["Break the world!"]
[The space around Kawaki, within a ten-meter radius, began to rapidly tear and collapse. He hastily used the Body Flicker Technique to escape.]
[As Kawaki carefully surveyed the battlefield, Shiro silently appeared behind him, startling him.]
[Kawaki immediately created distance between himself and Shiro. Seeing Shiro's head now sporting two new crescent-shaped horns, he hesitated and asked.]
["Are you Sarada's brother? Or Otsutsuki Kinshiki?"]
["You killed my sister."]
[Upon hearing Shiro's words, Kawaki confirmed that Shiro had not been completely assimilated by Kinshiki's consciousness, and he relaxed slightly.]
[In Kawaki's mind, as long as it wasn't the mysterious and unfathomable Otsutsuki clan, he didn't consider anyone else a threat.]
[Kawaki sneered at Shiro and mocked him.]
["So you're here for revenge, for your father and sister? Ha-ha..."]
[Facing Kawaki's arrogance, Shiro didn't respond. Instead, he decided to give Kawaki a gift he had never shown anyone before.]
["Susanoo!"]
[A black giant rose from the ground, its eight arms gripping eight 40-meter-long katana, slashing toward Kawaki's position.]
[Each katana was imbued with the power of "Shatter the World," causing the space it passed through to shatter.]
[The eight katana were danced in a dense, impenetrable formation, creating a spherical void that completely surrounded Kawaki.]
[Kawaki desperately released attacks, trying to break free, but every blow was consumed by the void, useless.]
[Shiro opened his right hand, his five fingers slowly closing. As he did so, the spherical void began to shrink.]
[When the void shrank to almost touching Kawaki's body, Shiro's five fingers suddenly clenched.]
[The spherical void erupted with a violent explosion, sending Kawaki flying out from the smoke, his seven orifices bleeding.]
[Kawaki quickly rose to his feet, screaming in horror.]
["Impossible! How could you have such powerful strength after just two months?!"]
[Shiro didn't answer his question. Instead, he glared and released a "Shatter the World" technique, severing Kawaki's right arm, covered with mysterious tattoos.]
[Shiro had realized that Kawaki's power came from the tattoos on his hands.]
[Sure enough, with his right hand destroyed, Kawaki's strength immediately weakened.]
[Shiro drew his sword from his waist and walked step by step toward Kawaki.]
[Whoosh!]
["Go and apologize to my sister below..."]
["Also, if you meet Uchiha Sasuke down there, tell him this: He doesn't deserve to be a father..."]
[Shiro's sword pierced Kawaki's heart in the exact same manner Kawaki had killed Sarada.]
[Upon seeing Kawaki's death, the surviving ninja forces erupted in loud cheers.]
[Hinata, along with the surviving Konoha ninjas, rushed toward Shiro. She wanted to express her gratitude for the late Seventh Hokage, Naruto Uzumaki.]
[As Hinata neared Shiro, before she could speak, Shiro suddenly gouged out her eyes, absorbing the chakra from them with his own eyes.]
Shiro:!!!∑(°Д°ノ)ノ
You actually dared gouge out Hinata's eyes?!
How am I supposed to face my future adopted daughter after doing this?
[Shiro released his suppressing force, and his Eternal Mangekyō Sharingan instantly evolved into the Rinnegan.]
[Now, his eyes combined the powers of the Byakugan and Sharingan, creating an eye even more powerful than the Rinnegan of the Six Paths Sage.]
[Seeing Hinata's eyes gouged out, Boruto, in a rage, raised his sword to strike Shiro, but Shiro grabbed Boruto by the throat with one hand, lifting him into the air.]
[Shiro looked at the sword in Boruto's hand, which once belonged to Sasuke, and sneered.]
["Hmph, you dare use that man's sword to attack me?!"]
["My sister is dead, but why are you still alive, the one she loved? Go down and join her!"]
[Crack!]
[Shiro snapped Boruto's neck.]
[The surrounding ninja forces, witnessing this sudden change, began to question why Shiro had done such a thing.]
["Shut up!"]
[Shiro glared, releasing "Shatter the World" and instantly killing over a thousand ninjas.]
["Ha-ha-ha-ha!"]
[His maddening laughter inflicted immense psychological trauma on the ninja forces.]
[Accompanying his deranged laughter, Shiro's overwhelming attacks fell upon the ninja forces, stronger than Kawaki's.]
[Before long, Shiro stood atop a corpse mountain, grander than Kawaki's, issuing his verdict on this world.]
["From today on, there is no need for the ninja world to exist. I will personally destroy it!"]
["I've spoken. Who agrees? Who opposes?"]
[The ninja forces never expected that after finally dealing with the insane Kawaki, they would face an even more deranged version of Shiro.]
[With the entire ninja world's survival at stake, the ninja forces were forced to launch another attack on Shiro.]
[Unfortunately, no matter how many there were, the weak ninjas were like ants that Shiro could squash with ease.]
[The battle lasted less than five hours, and the entire ninja army was slaughtered.]
[After the battle, Shiro's mind received Kinshiki's voice.]
["Don't forget your promise. After avenging your sister, you must willingly be assimilated by me and allow me to fully revive."]
["Don't worry, I remember."]
[Shiro released his mind and allowed Kinshiki's consciousness to begin eroding his self-awareness.]
[Soon, Kinshiki's consciousness completely took over Shiro's body, and Kinshiki revived.]
["Wait, this consciousness is… Shiro?!"]
["I said I would destroy the entire ninja world. How could I let you assimilate me so easily?"]
["Wait, wait…"]
[Just as Kinshiki was smugly celebrating, Shiro's original self-awareness, which should have been erased, suddenly surged and swallowed Kinshiki's consciousness completely.]
[It turned out that everything had been a plan by Shiro to use the Rinnegan's genjutsu to lure Kinshiki out.]
[After devouring Kinshiki's consciousness, Shiro took one last look at the sky above the ninja world and whispered.]
["Qin, Sarada, wait for me. I'll be there soon."]
[Shiro summoned his Susanoo, using the eight katana like a hoe to rapidly dig into the earth's core.]
[Three days later, having reached the core of the earth, Shiro gathered all his chakra into one point.]
[He detonated it, and the explosion's power shattered the earth's core. The entire ninja world exploded into countless fragments, becoming dust in the universe.]
[Shiro died.]
[Simulation ended.]
