Our journey leads to the sea of stars!

With this thought in mind, Kagami Uchiha looked up at the crack in the cave ceiling that Susanoo had torn open, gazing at the sliver of light that pierced the sky. His tone was calm and clear as he stated, "My plan for peace in the Shinobi World has only one thing: unification."

"To establish a unified nation, where there is no distinction between large and small countries, and where everyone shares the same identity and the same belief!"

"At that time, we will establish strict laws specifically targeting ninjas, a profession that possesses Natural Ability."

"The lives of all common people are guaranteed, and there are no longer any rulers like Daimyo."

"Everyone has the right to express their opinions about their country. There's no need to use a grand illusion like Infinite Tsukuyomi to forcibly change their minds."

"As long as the people are truly happy, they will wholeheartedly support and love this country."

"As for those few evil schemers, they absolutely cannot cause any trouble under the noses of people like us who have obtained the Rinnegan, which can even be considered immortal!"

At this point, Kagami Uchiha's expression brightened with excitement, and he said in a high-spirited tone, "At that time, everyone in the Shinobi World will unite closely to resist our common enemy."

"Whether it's the so-called Ōtsutsuki Clan or any other extraterrestrial species; anyone who dares to run rampant in our world will be annihilated!"

"Furthermore, if the Ōtsutsuki Clan can roam freely in the universe, why can't we?"

"By then, Madara-senpai, Little Black, our journey will be far more than just the vast Shinobi World."

Our journey is to the stars and the sea!

As soon as the words were spoken, not only Madara Uchiha, but also Black Zetsu, who was focused on saving his mother, were both stunned. Their understanding of the world was being severely shaken.

After a moment, Madara Uchiha looked puzzled and sighed, "Mirror! I never expected your vision to be so broad?"

"The stars and the sea? Can we mere mortals really challenge the stars in the sky?"

"Truly, upon first encountering the vastness of the sky and the immensity of the earth, one is struck by the boundlessness of the universe."

"Hashirama... you died too soon, if you were still here..."

Black Zetsu, standing to the side, also wore a look of longing, murmuring, "The vast universe? The world my mother once lived in?"

"If, after rescuing my mother, I could travel through the universe with her, that scene would be truly..."

Looking at Madara Uchiha and Black Zetsu, who were constantly sighing in front of him, Kagami Uchiha couldn't help but smile and think to himself: Sure enough, in this Shinobi World, no matter how old Madara is, he needs to receive ideological and cultural re-education!

With this thought in mind, Kagami Uchiha regained his composure, his expression returning to calm, and said lightly, "However, don't be too happy yet."

Upon hearing this, Madara and Black Zetsu once again became solemn, listening intently.

"Before that, there are a few steps. First, regarding the plan to unify the Shinobi World, given our current strength, conquering the various countries of the Shinobi World by force is not difficult; but it absolutely cannot be now. All actions have one crucial prerequisite—I must first condense my own Rinnegan."

He paused slightly, recalling the shadow lurking in the Fire Temple, a hint of seriousness creeping into his eyes; "The first threat we need to eliminate is Ōtsutsuki Isshiki."

"Hmph! Mirror, you don't need to worry. Let me kill that guy named Isshiki!" Madara Uchiha said coldly, his killing intent surging out.

The thought of all his hard work over the years turning into nothing fueled his murderous intent.

It's all because of those Ōtsutsuki Clan...

With this thought in mind, Madara Uchiha slightly turned his head to glance at Black Zetsu, thinking, "It's all because of you, you beast! You've made me the biggest joke!"

Sensing Madara's killing intent, Black Zetsu tensed up and immediately moved slowly toward Kagami Uchiha's feet.

Kagami Uchiha listened to Madara's words but did not agree. His expression was solemn. "Mada-senpai! Isshiki is not as simple as you think."

"Jigen is merely a temporary body he resides in. Once Isshiki leaves this physical body, he can unleash his full combat power in a short period of time."

"In the current Shinobi World, no one can stop him alone. Even if you regain the Rinnegan, you might not have a chance of winning against Isshiki at his Isshiki."

Upon hearing this, Madara Uchiha frowned. He once thought that he had finally managed to condense the Rinnegan, and even if Hashirama to be resurrected, he would be invincible in the world.

Unexpectedly, after becoming invincible, they've now encountered an enemy from outer space...

"Ōtsutsuki Isshiki..." he repeated the name under his breath, a genuine sense of unease rising in his heart for the first time. "Is this person really that terrifying?"

"Absolutely true!" Kagami Uchiha said decisively.

Looking at Madara who had calmed down, Kagami Uchiha continued, "The threat of Ōtsutsuki Isshiki hangs over all of us. And Isshiki is far from the end."

"Since Isshiki and Kaguya arrived on this planet, they have been out of contact with the Ōtsutsuki Main Family for a thousand years. I think it won't be long before another Ōtsutsuki Clan descends from beyond the heavens. At that time, we will face far more than just one or two, and every single member of the Ōtsutsuki possesses the Rinnegan!"

At this point, Kagami Uchiha paused, as if waiting for Madara and Black Zetsu to process the information. After a long while, he continued, "Regarding the Ōtsutsuki Clan, we have no choice but to resist. If we surrender without resistance, then the Shinobi World will truly have no future."

"To confront that clan head-on, one would at least need to possess the Rinnegan, or reach the level of the Sage of Six Paths."

"Besides, no matter how many people there are facing the Ōtsutsuki Clan, it's like an ant trying to shake a tree, or a mantis trying to stop a chariot!"

Madara Uchiha stood still, listening quietly.

"So, I plan to proceed in two steps."

"First: Right now, I won't rush to sweep across the Five Great Nations with my troops. Instead, I will gradually erode and weaken the power of each Ninja Village."

"Take the recently concluded Second Shinobi World War, for example. I captured the Four-Tails Iwagakure. I don't intend to return this Tailed Beast to Ōnoki. After returning to Konoha, I might choose a suitable vessel to create a brand new Four-Tail Jinchūriki and leave the Four-Tails in Konoha."

At this point, Kagami Uchiha's lips curled into a cold smile, "If Ōnoki is unwilling to accept this and wants to come and demand it, then we'll have to trouble Madara-senpai to make a trip there and let him properly recall the fear he felt when he was intimidated by the Uchiha back then."

Upon hearing this, Madara Uchiha appeared slightly dazed, lost in memories.

Ōnoki?

Could it be that short guy from Iwagakure back then?

Hah... That kind of trash dares to covet Konoha?

With this thought in mind, Madara Uchiha said disdainfully, "Fine, if that day ever comes, I'll go!"
