Rengoku brought Yakumo to Orochimaru's laboratory.
Yakumo spoke first, "Principal, Kaori-nee's soul strength has already reached 1.9, infinitely close to 2."
"Her recent headaches are because her soul strength is too high."
Rengoku asked with some curiosity, "What's going on?"
Yakumo shook her head, "Not clear, but Kaori-nee's soul strength has already surpassed Uncle Mayumi."
"I understand. Go rest first. I'll call you if I need you."
"Then Principal, I'll take my leave."
Kurama Yakumo was only called over now to test soul strength, but what exactly Rengoku wanted to do, she still didn't know.
Rengoku was also thinking of a suitable plan.
He went all the way down and arrived at the lower level of Orochimaru's lab.
"How is it? Is Kaori suitable?", Orochimaru asked.
He was quite looking forward to it. After all, the birth of a new Mangekyo was enough for him to collect a large amount of genetic mutation data.
This would be of great help to his progress in biological science.
Rengoku replied, "Her soul strength is extremely high, but how to stimulate her, that we'll have to think carefully about."
"Heh, with your eye techniques, weaving a story is nothing difficult," Orochimaru laughed.
Rengoku said helplessly, "Kaori cares most about Ryuri, but she would never believe I would harm Ryuri."
Orochimaru's eyes narrowed slightly, "That's simple, you can do a preset scenario reenactment."
———
[Late at Night]
Kaori rubbed her temples and woke up groggily.
She reached her hand to the side, empty.
'Where is Ryuri?'
Kaori instantly grew tense.
At this time voices came from outside the door. When Kaori heard them, her heart settled.
'It is Rengoku's voice, and another sinister one, Orochimaru?"
"Tsk! tsk! tsk! for the sake of moving forward, Clan Leader really spares no means," Orochimaru's voice was filled with sighs.
Rengoku's voice carried coldness and ruthlessness, "If it weren't for evolving my eyes, how could I still be raising this younger sister?"
"I worked so hard to climb to the clan leader's position, she should also give her final…"
"Now it's about time…"
Puchi!
The sound of a blade piercing flesh came from outside.
Kaori's heart trembled, her mind filled with unbelievable thoughts.
Her breathing grew rapid, and she suddenly yanked open the door.
Only to see Ryuri already lying in the courtyard covered in blood.
Rengoku was holding a jar, inside of which floated two eyeballs.
"RENGOKU! WHAT ARE YOU DOING?"
Immense fear, rage, disbelief, all surged into Kaori's heart.
Kaori was like a drowning person suddenly opening her eyes wide.
"Hooo…"
'So it was a dream…'
Kaori gasped with a face full of cold sweat. She thought, 'No wonder, how could Rengoku hurt Ryuri.'
While wiping her sweat, she reached to the side.
'Where's Ryuri?'
Kaori's heartbeat began to speed up, especially since she once again heard the voices of Rengoku and Orochimaru outside.
"Tsk! tsk! tsk! For the sake of moving forward, Clan Leader really spares no means."
Kaori pinched herself hard, her three-tomoe Sharingan spinning faster and faster.
'Not genjutsu! Not a dream!'
'It is real!'
Kaori didn't have time to think, grabbed the sword from the wall.
Pulled open the door and rushed out.
"If it weren't for evolving my eyes, how could I still be raising this younger sister…", Rengoku had just spoken this when he heard the sound of the door opening.
Kaori rushed out with a face full of grief and anger, "RENGOKU!"
Rengoku casually blocked, and with a side kick sent her flying.
A faint crackling sound, Kaori's sternum and ribs had already been broken.
Her chest flared with pain, and she spat out a mouthful of blood.
"So Kaori's awake, fine then. If you die together with Ryuri, I won't have to worry about her being alone in the Pure Land."
Rengoku's words were icy and merciless, plunging Kaori into both despair and fury.
Blood overflowed from the corner of her mouth, and she glared at Rengoku with unwillingness, "Why… Rengoku, why have you become like this?"
Rengoku spread his hands, face twisted in broken laughter, "What do you know? All these years I've struggled so hard outside."
"And how did you and Ryuri repay me?"
Rengoku reached out and in an instant Ryuri's two eyeballs were in his hand.
"No! Rengoku… what are you doing? She's your younger sister!"
Rengoku placed the eyeballs into the jar, his face twisted, "Exactly, it's because she's my sister that I kept her alive until now."
"Don't you know? The evolution of the Mangekyo Sharingan requires the eyes of one's closest kin?"
"You… Rengoku… YOU! BEAST!"
"Cough…", Kaori, with fractured sternum, coughed blood, her three-tomoe Sharingan spinning faster and faster.
Rengoku kicked Ryuri's corpse over to Kaori's side.
"Since she's already useless, I'll just send you both to die together!"
Rengoku formed hand seals:
Fire Style: Great Fireball Technique!
A massive fireball shot toward Ryuri's body.
"RYURI!", Kaori pounced with all her strength, finally covering Ryuri's body.
The giant fireball closed in, the searing pain crazily ravaging Kaori's nerves.
Rengoku wanted to burn them both to death.
Kaori clutched Ryuri tightly, crying in anguish, "RENGOKU, I HATE YOU…! AH! AH! AH!…"
Her three-tomoe Sharingan spun madly, finally linking end to end.
Like a serpent biting its tail in an eternal cycle.
Immense pupil power surged out.
The next instant, Kaori and Ryuri's bodies vanished.
Rengoku clenched his hand, and the Great Fireball exploded into a sky of embers and disappeared.
The next instant, a blade appeared out of the void and pierced directly into Rengoku's heart.
"Cough! Cough! Cough!", Kaori, holding Ryuri, coughed blood, tears of blood flowing from her eyes as she emerged from the void.
Blood sprayed from Rengoku's mouth as he fell backward.
Seeing Rengoku killed, Kaori's spirit slackened, and she blacked out.
From the side room, another Rengoku stepped out, while the previous Rengoku sank into the shadows of the ground.
That had only been his clone.
Orochimaru, who had been watching from the start, immediately stepped forward.
He quickly checked Kaori's condition.
"Seems Rengoku, you are a ruthless man as well."
Seeing Kaori left with only a single breath, Orochimaru stuck out his tongue to wash his own face.
As half a medical ninja, he began emergency treatment for Kaori, after all Rengoku's clone's kick just now had been full force.
Rengoku too felt immense pressure. If by accident Kaori died, he really wouldn't know how to explain it to her sister.
Kaori not only had her sternum broken, but her ribs too, and when she forcibly killed his clone just now, her broken rib had even pierced into her internal organs.
Rengoku placed his hand on Kaori's body, beginning to use Mystical Palm Technique to slow the internal bleeding.
"There's no choice. This chance comes only once. If we're not ruthless, it might all fail."
Orochimaru quickly reset her ribs, pulled out a bottle, and poured some liquid down Kaori's throat.
Kaori's breathing finally eased a little.
"Her spirit hasn't collapsed. She's only in deep coma now."
"Looks like a soul power close to 2 is indeed enough to awaken the Mangekyo Sharingan."
