It's just a fatal wound. Bear with it!
At this point, Madara Uchiha could no longer sit still.
His decades of planning and lifelong obsession, in the end, were nothing more than a game of chess set up by Black Zetsu?
In an instant, a tremendous sense of humiliation at being manipulated and an endless hatred at having one's beliefs shattered erupted.
Madara Uchiha abruptly raised his head, his gray hair standing on end, his aged and withered body now bursting with a violent and chilling killing intent. He growled hoarsely, "Black Zetsu, you bastard! -- How dare you..."
Before he could finish speaking, Madara's right eye instantly transformed into a scarlet Sharingan, and blue Susanoo bones suddenly appeared around his body. As the outline expanded, the deep blue Susanoo, and the entire cave was forced open as Susanoo appeared, with rubble raining down like a storm.
As Susanoo's body continued to grow, the entire cave shook violently, and the rock strata at the top continued to crack. Madara Uchiha stood in the center of Susanoo's skeleton, his turbid eyes filled with boundless rage.
Then he suddenly raised his right arm, and a blue Chakra Blade instantly appeared in Susanoo's bone palm, carrying the meaning of destroying everything, and slashed down at Black Zetsu.
"Wait, Lord Madara! You can't believe Kagami Uchiha's one-sided story! I have something else to say..."
Before the blade even truly got close, Black Zetsu was already pressed to the ground by that terrifying aura. It hurriedly tried to speak, wanting to explain, but Madara Uchiha ignored it. The sharp blade light of Susanoo continued to magnify in Black Zetsu's pupils.
Boom--!
"Holy crap!"
The deep blue blade of light slashed fiercely at Black Zetsu, creating a deep, bottomless crack in the ground behind it. As the aftershocks of the blade dissipated, Black Zetsu's body was almost completely severed by the blow, viscous black liquid splattering everywhere. Its mangled shell twisted and struggled wildly on the ground, unable to even utter a scream, only convulsing in a deathly state.
Hot tears slowly streamed down its face. "It hurts so much... Mommy."
It had survived in the Shinobi World for a thousand years, and had never experienced such a painful moment, nor had it ever come so close to death.
Seeing this, Madara Uchiha felt no pity whatsoever; all he wanted to do was to shred this monster, who wasn't even human, into dust.
With this thought in mind, the Sharingan in his eyes became even more ferocious, and he raised his hand to deliver another blow.
Just then, Kagami Uchiha stepped forward and calmly said, "Don't be in a hurry, Madara-senpai."
Upon hearing this, Madara Uchiha paused in his actions, and the giant sword of Susanoo stopped in mid-air, only half a meter away from Black Zetsu's head.
He slowly turned his head, his gaze fixed on Kagami Uchiha, his expression cold and stern, and he asked in a low voice, "Are you going to stop me?"
Kagami Uchiha shook his head slightly and replied calmly, "I'm not stopping you, it's just that letting something like this die so easily is too good for it."
At this point, his gaze fell on the half-dead Black Zetsu, his eyes calm, and he slowly spoke, "I wonder if Senior Madara would allow me to have a proper talk with this brother of the Sage of Six Paths?"
--
The smoke from the battle had not yet dissipated inside the cave. Black Zetsu lay panting on the cracked, cold ground. Its entire body had been cleaved to pieces by Madara Uchiha, and it had almost met its end.
Kagami Uchiha slowly walked up to Black Zetsu, looking down at the twisting, eerie black mass, and said calmly, "Black Zetsu, I think Madara-senpai's attack, while it could severely injure you, wouldn't be enough to kill you."
"It's just a minor fatal wound. Bear with it, recover your strength, and I'd like to have a chat with you."
Upon hearing this, Black Zetsu, who was lying on the ground convulsing in pain, suddenly stopped.
Damn it... do you want to hear what you're saying?
A mere fatal wound? You expect me to bear with your nonsense?
Damn it! That heartless brat Kagami Uchiha is a real beast!
Hmph! Even if you lose the battle, you can't lose face! I'll hear what this kid has to say.
Immediately, Black Zetsu slowly rose to his feet, his expression unreadable, his voice hoarse. "Heh... I've been wandering the Shinobi World for a thousand years, never expecting to be exposed by a mere brat like you."
"The powerful figures in the Shinobi World are as numerous as carp crossing a river!"
"Just say it! What do you want to say to this old man?"
Seeing this, Kagami Uchiha remained calm and said indifferently, "Black Zetsu, I'll call you that. Or Ōtsutsuki Black Zetsu is fine too, what do you think?"
Upon hearing this, Black Zetsu on the other side immediately lost its composure and hurriedly said, "You! How do you know about the Ōtsutsuki? Did the person next to you tell you? Heh... then it's not surprising." As it said this, it glanced disdainfully at Madara Uchiha.
"Damn it! Mirror, don't stop me, let me kill it!" Madara Uchiha, who was standing to the side, suddenly flew into a rage and raised his sword to strike.
Although Black Zetsu's face was completely black, Madara could still sense the disdain this dark monster had for him.
"Alright, Madara-senpai, calm down. Even if you kill it, it won't erase the fact that you've been toyed with by this guy for decades." Kagami Uchiha quickly stepped between Madara and Black Zetsu to mediate.
Upon hearing this, Madara Uchiha had no choice but to stop what he was doing and stare intently at Kagami Uchiha and Black Zetsu.
He wanted to see what these two guys could talk about.
"Hmm... Black Zetsu, my understanding of the Ōtsutsuki goes far beyond what you wrote on the stone tablet; it includes everything that happened a thousand years ago."
"Oh, and your mother's true background too."
At this point, Kagami Uchiha's lips curled into a slight smile, tinged with a hint of mockery.
"By the way, do you know about your mother's past?"
"This..." Upon hearing this, Black Zetsu's figure swayed slightly, and he said in a deep voice, "Hmph! You are nothing but a descendant of Indra, what could you possibly know?"
"I know your mother is from the Ōtsutsuki Clan, who came from outer space; I also know your mother's purpose in planting the God Tree; and I know even more about your purpose in deceiving Madara-senpai to create the White Zetsu!"
"What? You, how did you know? These secrets, besides the deceased Hagoromo and Hamura, are known only to my mother and me in the current Shinobi World." Black Zetsu's expression changed drastically, and he said in disbelief.
Seeing this, Kagami Uchiha smiled faintly and slowly said, "Then let me ask you, you are so eager to revive your mother Kaguya, but do you know who the mortal enemy your mother faced when she desperately created the White Zetsu was?"
Upon hearing this, Black Zetsu's trembling body suddenly froze.
It knew that its mother created the White Zetsu to defend against her enemies, but for thousands of years, it had searched through the entire history of the Shinobi World and read countless fragments of inscriptions and hidden scrolls, yet it had never learned a single piece of information about that great enemy.
It's important to understand that if it weren't for creating White Zetsu, Mother wouldn't have fallen out with her two rebellious sons, Hagoromo and Hamura. But faced with that enemy, Mother was willing to harm her own sons rather than give up and continue creating White Zetsu.
To be honest, it didn't think much of any of the White Zetsu created by Madara. Apart from their slightly stronger life force and their foul mouths, these creations were completely useless.
With this thought in mind, Black Zetsu endured the pain, his expression serious, and asked in a deep voice, "Then tell me, what exactly is the identity of that formidable enemy?"
Hmph! Looks like I need to find a way to get out of here.
It has more important things to do: anyone who threatens Mother, I must get rid of them!
