Saving the Uchiha clan starts with becoming the clan leader.

Zongxian said calmly,

Fearing that Madara Uchiha wouldn't believe him, he dropped the katana in his right hand, and a high density of chakra surged from his palm, instantly condensing into a Truth-Seeking Ball.

Then he asked:

"So, did you understand?"

Madara Uchiha remained silent.

His face was extremely pale. He knew that what Uchiha Sogen said was true, but... it was precisely because it was true that it was the hardest to accept. He had gone to great lengths and used all his efforts to become the Ten-Tails' Jinchūriki and wield such power, but Uchiha Sogen didn't even need the Ten-Tails' power to help him wield the Truth-Seeking Balls.

"It's not over yet!"

Madara Uchiha gritted his teeth. The huge wound on his left abdomen had not killed him. The Ten-Tails Jinchuriki's vitality was obviously extraordinary, especially since he also had Hashirama Senju's cells. The flesh and blood at the wound site were regenerating.

He suppressed his anxiety.

We must not lose our composure.

Even if Uchiha Sogen had mastered the Truth-Seeking Balls without the help of the Ten-Tails, so what? The Ten-Tails Jinchuriki possessed more than just the Truth-Seeking Balls; he had many other methods he hadn't yet used. This battle was far from over!

He gritted his teeth and unleashed one of his most powerful and secret techniques.

"Wheel Graveyard - Border Prison"

Four shadows, invisible and imperceptible to ordinary people, emerged from his body and pounced towards Zong Xian.

"Uchiha Madara, you're not the only one with the Rinnegan!"

Seeing the four shadows rushing towards him, Zongxian twirled the 'Heavenly Swamp Spear' in his hand and swiftly severed the four shadows, causing Uchiha Madara's expression to change drastically. He knew that Zongxian could see the shadows he had created using Limbo.

but,

Isn't that strange sword in Uchiha Sogen's hand a bit too sharp?

He actually cleaved all his shadows in two with a single sword strike. Of course, these shadows didn't completely disappear; they could be summoned back after a while. But the problem was that even if they were summoned back, it wouldn't be of any use. They couldn't withstand that long sword; they would just be easy prey for someone to chop up.

"It's the Heavenly Spear!"

Hidden in the shadows, Black Zetsu recognized the sword.

He had never seen it in person before, but he had an impression of this sword in his memory of Kaguya Otsutsuki. It was a divine weapon created by the Sage of Six Paths, Hagoromo Otsutsuki, using Truth-Seeking Balls. The wielder's beliefs would attach to the sword, creating a sword of the heart.

As long as the wielder's conviction remains unwavering, this sword of the heart is indestructible and invincible.

then,

Hagoromo Otsutsuki successfully used this sword to severely injure his mother, Kaguya Otsutsuki, creating an opportunity to seal Kaguya away.

"This can't go on! Madara... he's really useless!"

Seeing Madara Uchiha being forced to retreat by Sogen's Tenma Spear, Black Zetsu realized the situation was dire and could not delay any longer. Although Madara Uchiha had not yet released Infinite Tsukuyomi, ... resurrecting his mother did not actually require the Infinite Tsukuyomi step.

if only,

Seize the opportunity to disrupt the chakra balance within Madara Uchiha's body.

It's like—

Madara Uchiha swung his staff to block the attack of the Tenma Spear for a moment, buying himself a little time to move. He wasn't cleaved in two, but his face and chest were slashed, revealing his beating heart. He then fell to the ground below.

Before he could get up again,

A black arm pierced through his chest; Black Zetsu had decisively betrayed Madara Uchiha.

"Black Zetsu, you...you bastard..."

Madara Uchiha turned around in disbelief to look at Black Zetsu behind him. He really couldn't imagine that Black Zetsu would betray him, even though... Black Zetsu was the embodiment of his will.

"spot!!!"

Obito Uchiha was stunned when he saw this.

What the hell is going on?

Not just him,

The people on Konoha's side were equally dumbfounded. Was this... an internal conflict?

"Why? Black Zetsu, what are you doing?"

"I'm doing what I should do, Madara. Your mission is over. Next... it's time for my mother to take the stage." At this moment, Black Zetsu had no interest in answering Madara's questions. He simply guided the Ten-Tails within Madara's body to go berserk, following the method left to him by Kaguya Otsutsuki.

"Mother? You... who exactly are you..."

Madara Uchiha was not a fool.

Although he didn't know who Black Zetsu's mother was, it was clear that Black Zetsu was not the embodiment of his will; he... had been deceived.

The ten-tailed beast within him went berserk, and his consciousness became hazy.

In a trance,

He remembered Hashirama.

He couldn't help but laugh at himself. It seemed that the peace he had pursued... was ultimately just a mirage! Now that he was in the Underworld, he really had no face to see Hashirama again... His consciousness then plunged into darkness.

Simultaneously,

His appearance has changed dramatically once again.

Its body swelled up like an inflated balloon, turning into a huge sphere in the blink of an eye. At this point, it seemed to have reached its limit and stopped, then began to contract, constantly correcting its shape during the contraction process.

In just three to five seconds, a woman with long white hair cascading to the ground, two horns on her head, a crimson nine-tomoe Sharingan between her brows, pure white eyes, wearing wide robes and sleeves, and exuding a cool and aloof temperament, appeared in everyone's sight.

Kaguya Otsutsuki,

recovery,

Come.

"Why is my chakra... so little?"

Kaguya Otsutsuki ignored everyone around her. She lowered her head, her pure white eyes staring intently at the Black Zetsu that had merged into her sleeve, and questioned him.

"Mother, the plan..."

"We've finally waited for this moment."

Zongxian's voice interrupted Black Zetsu's speech.

He floated down to Kaguya Otsutsuki, looked at the progenitor of chakra, and said, "Now, it's time to return what's mine." As he spoke, he extended his right hand and gently hooked his finger. Kaguya Otsutsuki, who looked up unhappily, didn't even have time to see clearly the face of this human who dared to interrupt so casually.

Suddenly, I felt a surge of power within my body.

The Ten-Tails suddenly went berserk, forcefully breaking free from her body and falling under Zongxian's control.

Before Madara Uchiha used the Six Paths Ten-Tails Coffin Seal to absorb the Ten-Tails, Sogen had already used the power of 'Knights Never Die Barehanded' to bring the Ten-Tails, this weapon of war, under his control. Madara Uchiha was able to successfully absorb the Ten-Tails entirely because of Sogen's active cooperation, in order to find a vessel for Kaguya Otsutsuki's revival.

Ten-tailed

He was under Zongxian's control from beginning to end.

Now that Kaguya Otsutsuki has been revived, the Ten-Tails can be retrieved.

"Next... let me try to help the Ten-Tails reclaim its lost Chakra Fruit!" With long white hair, wearing a white cloak, nine Truth-Seeking Balls floating behind him, and wielding the Tenma Spear, Sogen extended a challenge to the weakened Kaguya Otsutsuki.

then,

Zongxian utterly defeated his ancestor, who was now greatly weakened and lacked combat experience.

Kaguya Otsutsuki, who was defeated, was not sealed away. Sogen was very interested in both the chakra fruit that Kaguya had devoured and the information about the Otsutsuki clan in the starry sky. Keeping Kaguya alive might be of great use in the future!

We can only wait and see what the future holds.

But once Black Zetsu, the mastermind behind everything, is dealt with, the ninja world... will be able to usher in a long period of peace!
