Uchiha Kō successfully fused with the Sharingan. He opened his eyes, and his pupils changed from black to the Eternal Mangekyō Sharingan, and then from the Eternal Mangekyō Sharingan to the Orange Rinnegan. The Rinnegan had no Tomoe, it was just that simple and unadorned.
Uchiha Kō was taken aback. He stood up, looked in the mirror, and examined his Rinnegan. He asked, "System, is the ability of my Rinnegan a little too ordinary?"
"Ding! Due to the overwhelming power of the Orange Rinnegan, 90% of its abilities have been sealed, leaving only the basic Rinnegan abilities: Chakra Absorption, Banshō Ten'in, Shinra Tensei, and Chibaku Tensei."
"The host's physical body is insufficient to withstand the full power of the Orange Rinnegan. Once unsealed, the Orange Rinnegan will drain the host dry and destroy the entire world!"
Uchiha Kō nodded. "Then, is there a way to turn it off?"
"Yes." After saying that, the system taught Uchiha Kō how to turn it off and on. Uchiha Kō's pupils returned to black, and he could switch back and forth between the Mangekyo and the Rinnegan whenever he wanted.
"Please note, host, although the Orange Rinnegan is sealed and lacks the Tomoe, its power is still enough to completely overwhelm Uchiha's pair." The system's voice carried a hint of amusement.
Uchiha Kō didn't forget to infuse a trace of his soul power into the Substitute Death Puppet and place it next to the Shadow Clone.
Uchiha Kō nodded. "Let's set off now and investigate the reason for our unease."
The system remained silent, but inwardly acknowledged Uchiha Kō's thoughts.
Uchiha Kō made up his mind and created a clone with 90% of his abilities in the room. He then absorbed Natural Chakra replenish himself. About two hours later, he opened his eyes and Flying Thunder God Technique to teleport to Namikaze Minato's side.
After Uchiha Kō left, the tightly closed bedroom door opened, and Tsunade looked at the Shadow Clone on the sofa with a worried expression. The Saiken -Tsunade what had happened in the living room.
However, she only knew about Uchiha Kō creating clones and teleporting away; as for the substitute puppet, she knew nothing about it.
"Lord Xiao, you must return safely." Tsunade felt a void in her heart, as if something was about to leave her. This feeling was very uncomfortable, yet incredibly real.
During the march
Namikaze Minato was taken aback. He sensed a familiar chakra and the aura of the Flying Thunder God Technique, and frowned, but found nothing.
Uchiha Kō wiped away his sweat and let out a breath. Namikaze Minato's sensory abilities were truly astonishing. If it weren't for his combination of Flying Thunder God and Body Flicker Technique, he wouldn't have been able to avoid being discovered.
Uchiha Kō concealed himself and followed behind. If he didn't want to, even Uchiha wouldn't be able to find him. Seeing that the army was resting Uchiha Kō didn't say anything.
"Ding, host, should we conduct this investigation on our own or follow the main group?" the system asked.
Uchiha Kō hesitated for a moment, then his eyes hardened. "Let's go first." With that, he broke away from the main group and headed towards the Twin Mountains on the border of the Land of Wind in the distance.
In a short while, he arrived at a point a thousand meters from the mountain. Uchiha Kō asked, "How is it, System? Can you sense it?"
The system was operating at full capacity. Soon after, a series of garbled sounds echoed in Uchiha Kō's mind. After a while, it recovered and said with a solemn expression, "Host, the specific cause cannot be detected, but there are traces and auras left by the Heavenly Dao of the Hokage world."
Uchiha Kō's heart sank. The Heavenly Dao, huh? It really thinks highly of itself. Even though it's separated from the original plane, the Heavenly Dao can still interfere.
Sunagakure Camp
Rasa sat in his chair, continuously analyzing the upcoming battle plan.
Suddenly, Black Zetsu's voice rang out, accompanied by excitement.
"Rasa! Let's go quickly! Uchiha Kō has appeared at this location! He's all alone!" Black Zetsu's face lit up with joy. Just now, he had heard his mother's voice.
"My child, that guy who's disrupting the Ninja World's order has appeared alone, just a thousand meters from Mt. Kikyo." After saying that, he sent the map marker to Black Zetsu through his soul.
Black Zetsu has unwavering faith in this mother. On one hand, his plans have completely collapsed, and on the other hand, he has no one else to rely on, so now he clings to her as a lifeline whenever there is even a glimmer of hope.
"Mother, I understand. I'll set off now!"
"Hmm." The sound faded, and all was silent.
"Rasa, what are you waiting for! Go now! As long as we eliminate this guy, Sunagakure will usher in a great change that has not been seen in a century!" Black Zetsu's voice was seductive.
Rasa narrowed his eyes. "Black Zetsu, how many people do we need to bring?" Rasa didn't disagree with Black Zetsu's approach, but he didn't fight unprepared battles.
"Go alone. Too many people will alert Uchiha Kō. If he runs away, then such an opportunity will be hard to come by again!" Black Zetsu originally planned to use the trump card his mother gave him to control Uchiha, but who knew that a new opportunity would arise.
"Let me confirm again, you can handle Uchiha Kō, right?" Rasa asked again out of caution.
Black Zetsu was getting a little impatient, but he didn't show it. "Don't worry, I can, but you need to stall him for a minute first. I need to prepare."
"Moreover, it can't be prepared in advance, otherwise he'll notice." Black Zetsu's voice rang out, carrying endless chill.
These are things Black Zetsu learned through communication with his mother; they can only be prepared now, not in advance.
"One minute? That's a bit difficult. I'll need to borrow your power then," Rasa said after thinking for a moment.
Black Zetsu nodded. "Of course! You and I have waited eight years for this day! We will eliminate this long-standing threat at all costs!"
Without further hesitation, Rasa arranged all military affairs, then stepped onto the Gold Dust Platform and floated towards the direction where Uchiha Kō was.
Uchiha Kō: "So what should we do now?"
"Observe the situation carefully, host!" the system notification sounded.
A purple Kunai shot towards Uchiha Kō. Uchiha Kō was startled, then dodged it. Just then, the purple Kunai suddenly disappeared, and then a huge purple light curtain enveloped him.
Uchiha Kō frowned and Flying Thunder God Technique, only to find that he couldn't. His sense of crisis immediately intensified.
"What's going on, System!" Uchiha Kō roared inwardly, his expression unchanged.
The system gritted its teeth, "Host, this is a spatial sealing talisman from the Heavenly Dao! It cannot be broken unless the caster is defeated!"
"The caster? Who is the caster? The Heavenly Dao? How can I possibly defeat them!" Uchiha Kō took a deep breath.
The system replied, "No, the Heavenly Dao and my ideology are similar. I cannot act personally; I can only use others to deal with the host."
Just as Uchiha Kō frowned, pondering who it could be, a long spear made of Gold Dust shot towards him!
Whoosh!
The spear spun rapidly, aiming for Uchiha Kō's brow. Uchiha Kō activated his Mangekyō Sharingan, tracked the spear's trajectory, dodged to the side, gripped the golden spear in his right hand, and fired it back at an even faster speed in the direction it had come from!
Rasa frowned, extended his right hand, and made a prohibition gesture. The golden spear turned into Gold Dust and dissipated, a mocking expression on his face.
"Rasa!" Uchiha Kō's eyes darkened as he looked in Rasa's direction.
Rasa appeared before him with a forced smile. "Heh, Uchiha Kō, long time no see. How's the effect of this sealed territory Kunai? Pretty good, right? Is there no way to break through it?"
Uchiha Kō murmured, "You are the caster?"
"That's right, but you can't hit me." Before he could finish speaking, Uchiha Kō threw a punch that pierced Rasa's throat. As a result, Rasa's voice faltered, and he turned into a bowl of Gold Dust and disappeared on the spot.
"A clone?" Uchiha Kō coldly. Just then, the system voice sounded, "Host, this is bad! The Heavenly Dao has made its move. It wants to obliterate your soul and then forcibly correct this world, returning it to its original plot."
Uchiha Kō was shocked. He hadn't expected the Heavenly Dao to be so ruthless! How could this peaceful Ninja World be something he didn't want? What exactly was it planning to do?
"It's too late! Host, quickly find Rasa's location! Kill him, then leave this place!" The system's voice was urgent.
Uchiha Kō nodded, and his eyes changed again, turning golden, with circles appearing in them.
Black Zetsu, who had been secretly preparing and observing, paused. Those eyes! They belonged to his mother's kind! No, that's not right! They belonged to his mother's enemy!
He gritted his teeth and desperately channeled his chakra into the techniques his mother had given him.
Uchiha Kō's eyes turned gold, and his vision became much clearer in an instant, allowing him to instantly locate Rasa's hiding place.
He charged toward Rasa, Rasa remained unfazed and summoned over a hundred Gold Dust weapons, which shot toward Uchiha Kō.
Uchiha Kō said calmly, "Almighty Push!" A golden light emanated from the center of Uchiha Kō and then spread outwards.
The Gold Dust weapon vanished instantly, leaving not a single grain. Uchiha Kō's momentum didn't falter; his gaze locked onto Rasa, and he extended his right hand, unleashing the "Ten Thousand Shrinking Heavenly Yin!"
Rasa felt a tremendous suction force pulling his body. He quickly exerted force with his legs, but still could not resist the downward trend. He gritted his teeth and Hand Seals.
The Substitution Technique was used, and the original location of Rasa was transformed into a wooden stake, which was then absorbed by Uchiha Kō.
After acquiring it, Uchiha Kō squeezed the wooden stake with his right hand, and it snapped.
Uchiha Kō continued searching for Rasa. Rasa's expression changed drastically. In less than twenty seconds, damn it, why is Uchiha Kō so strong!
We're all Kage, so why?! Why are the Hokage's fighting power so outrageous?!
"Black Zetsu, lend me your power!" Rasa said through gritted teeth.
Black Zetsu nodded and lent Rasa Otsutsuki chakra. Rasa's aura changed; the corners of his mouth turned up, two bumps appeared on his head, and his skin became several shades lighter.
Uchiha Kō was taken aback, and the system explained, "It's Black Zetsu. He became a pawn of the Heavenly Dao! The Power of the Deva Path helped him activate the power of the Ōtsutsuki Clan. Although it's not much, it allows him to do so much more!"
