In the small courtyard.
Hamura looked at his older brother, who was calling his name, with a completely bewildered expression.
The screams were so pitiful, as if the person had died...
Kaguya glanced at Uchiha Kei of shrewdness flashing in her eyes.
This is...
Genjutsu?
Genjutsu cast by the Sharingan?
As an Otsutsuki Clan, she certainly had this much knowledge.
The Genjutsu used by Uchiha Kei was far superior to hers; she hadn't even seen many comparable ones in Takamagahara.
At that moment, she believed even more deeply what Uchiha Kei had said.
When Hagoromo's eyes transformed into the Rinnegan, Uchiha Kei raised his head and gently snapped his fingers.
Feathered Hagoromo trembled as she knelt in anguish, glancing blankly at the figure before her, her face streaked with tears.
"Brother, are you alright?"
Hamura walked up to him with concern.
Hagoromo raised his head in disbelief, looking at Hamura was completely unharmed.
Under Hamura's shocked gaze, he pulled her into his arms.
"Hamura... Hamura... you're alright... that's great!"
As she spoke, Hagoromo's tears continued to flow uncontrollably.
Uchiha Kei raised an eyebrow.
Was the Genjutsu too powerful?
Haven't you gotten over it after all this time?
"Alright, stop hugging. Aren't you two old men ashamed?"
Uchiha Kei stood up from the recliner and slowly walked to the two people who were embracing tightly.
Hamura pushed his brother away with difficulty, a blush creeping onto his face.
Hagoromo was breathing heavily, desperately trying to calm her turbulent emotions.
Uchiha Kei wasn't in a hurry; he quietly waited for Hagoromo to regain her composure.
A long time.
"Teacher, was that Genjutsu?"
Hagoromo Yi wiped the tears from her face and looked at Uchiha Kei.
Uchiha Kei. "You should have known about the Sharingan's abilities when you awakened it. Genjutsu is just the most basic ability of the Sharingan."
Hagoromo nodded silently.
He already knew the moment the Genjutsu shattered.
But Uchiha Kei's Genjutsu was so realistic that he couldn't distinguish between reality and illusion, whether it was the dead Hamura or the blood on his hands.
"Now that you have advanced to the Rinnegan, the instruction shall officially begin."
Uchiha Kei narrowed his eyes and looked at the two brothers with a smile.
For some reason, when faced with that smile, Hagoromo Hamura suddenly felt a chill run down their spines.
Uchiha Kei led the two to the center of the courtyard. "I can't teach you any Ninjutsu; you'll have to figure that out yourselves."
Ninjutsu?
The two brothers exchanged a glance, both seeing confusion in each other's eyes.
Another new ranking.
Ignoring their questions, Uchiha Kei continued, "What I can do is purify your bloodline as much as possible, even beyond the constraints of the Otsutsuki Clan."
Hamura seemed to have thought of something, and his expression immediately turned somewhat grim.
"Teacher... didn't we agree that I'd have the day off today?"
Hamura's voice became very melancholic.
"Really? I don't remember."
Uchiha Kei, suffering from amnesia, looked at Kaguya with confusion, "Kaguya, did I say that?"
Kaguya understood immediately and shook her head.
Hamura's face darkened further, but the situation was beyond his control, so he could only grit his teeth and persevere.
This Hagoromo's first experience, and she had no idea what would happen next. She looked at Uchiha Kei.
"Whoosh!"
A bright light suddenly appeared in Uchiha Kei's hand.
Even with the Sharingan's keen perception, Hagoromo couldn't detect where the light was coming from.
Soon, the light faded, and a whip covered in spikes appeared in Uchiha Kei's hand.
"To reap rewards, one must endure hardship. Bloodline Enhancement is a very difficult thing, so extraordinary means must be used."
Upon seeing the whip, Hamura instinctively shuddered, and his face turned deathly pale at a visible speed.
Hagoromo was still confused.
Bloodline Enhancement...
What does this have to do with whips?
He had barely opened his mouth to ask a question when a dark shadow hurtled straight at him.
Hagoromo instinctively tried to dodge, but his body felt like it wasn't his own. No matter how he tried to control it, he couldn't move and could only watch helplessly as the dark shadow approached.
"Smack!"
A crisp sound rang out in the courtyard.
A bloody, mangled gash appeared on Hagoromo's bare upper body.
Hagoromo's body began to tremble violently, and the immense pain seemed to pierce through his soul, repeatedly pushing his limits of endurance.
"Smack!"
"Smack!"
"Smack!"
The whip, like a phantom, left one hideous wound after another on Hagoromo's body, and blood was already all over his body, with much of it flowing down his ankles to the ground.
And the pain of that distance seems to accumulate.
With each lash, the pain doubles!
But he was frozen in place, unable to move at all!
Not only can he not move, he can't even scream anymore.
The whipping did not stop; it continued, and even increased in speed.
With each crack of the whip, Hamura trembled, and beads of cold sweat began to appear on his forehead.
For those six days, he experienced the power of this little whip almost every day.
That kind of pain, which came from the depths of his soul, would send shivers down his spine whenever he thought about it.
Pain!
It hurts so much!
The kind of pain that can kill you!
Kaguya watched quietly as well, without offering any indication of stopping them.
As Otsutsuki Clan, and with Hagoromo and Hamura being her children, she could clearly feel that with each whipping, the bloodline within Hagoromo was being elevated!
Bloodlines are fixed in Takamagahara.
What kind of bloodline you are born with is what you will become in the future; it is impossible to change that.
And now, she has witnessed firsthand the leap in her son's bloodline!
If Uchiha Kei hadn't said that this method wasn't suitable for her, she would have wanted to give it a try.
It's just a few lashes, isn't it?
Compared to their actual strength, they are utterly insignificant!
Uchiha Kei only stopped whipping Hagoromo after there wasn't a single good spot left on his body.
At that very moment, Hagoromo regained control of her body.
"Ah!"
Hagoromo's heart-wrenching scream rang out instantly, and her body involuntarily collapsed to the ground.
The unbearable pain caused his entire body to spasm.
Uchiha Kei just watched quietly.
A long time.
The pain gradually subsided, and the wounds on my body were healing rapidly.
The instant all his wounds healed, Hagoromo's body suddenly floated up, with specks of white light appearing and disappearing within him.
Kaguya looked at the white lights with a complicated expression.
This is...
The embodiment of bloodline purification.
If we say that Hagoromo's bloodline purity was 50% before...
So when he completely merged with these white lights, his bloodline purity increased to at least 60%!
Don't underestimate this 10% improvement.
Even the most talented Otsutsuki from Takamagahara couldn't improve the purity of his bloodline!
Moreover, a 10% increase is enough to significantly improve Hagoromo's strength.
"Boom!"
After the white light dimmed, the Hagoromo fell heavily from mid-air.
Ignoring the dust covering her body, Hagoromo scrambled to her feet, an excited look on her face.
He sensed it.
His strength, his bloodline power, and his Rinnegan have all greatly improved compared to before!
"Teacher, I've recovered!"
Hagoromo stared intently at Uchiha Kei.
"Please encourage me, teacher!"
One sentence left Hamura speechless.
Elder brother...
Does she have some little-known quirk?
Thinking this, Hamura subconsciously distanced himself from his brother.
