"So what next?" Rin looked at Geto Suguru, his voice tinged with confusion.
Having just understood the characteristic of the Sharingan storing Cursed Techniques, he hadn't had time to sort out the subsequent direction and could only ask the only person he could rely on at the moment.
Geto Suguru nodded slowly upon hearing this, his eyes showing a newfound certainty:
"Next, I will use a special method to examine your brain, thoroughly ascertain the true condition of the Cursed Techniques in your brain region, whether there are any residual copied Cursed Techniques, and if your Innate Cursed Technique is stable. Everything will be clear."
He paused, then added:
"This method was originally a secret technique of the great Jujutsu families in Japan, specifically used to detect whether children in the family had awakened their 'Innate Cursed Technique'. After all, the imprints of Innate Cursed Techniques are often hidden extremely deep, and ordinary detection methods cannot capture them. Only this secret technique can accurately reach the core of the brain region without causing any damage to the body. It's perfectly suited for your current examination."
Hearing Geto Suguru's words, Rin nodded in agreement. He had learned about this method in the anime in his previous life. In the plot, Fushiguro Toji once mentioned that his son, Fushiguro Megumi, would be able to be tested for a Cursed Technique in a few years.
This method was also very suitable for his current situation.
Geto Suguru walked over to stand opposite Rin.
He raised his hand and rolled up the sleeve of his black monk robe to his forearm, revealing his smoothly contoured wrist.
The next second, a very faint layer of black Cursed Energy slowly appeared in his palm.
"Relax, focus your attention on your brain, and do not resist my Cursed Energy."
Geto Suguru's voice was calm and deep, carrying a reassuring power.
He slowly raised his hands and gently placed them on Rin's temples. The Cursed Energy in his palms seeped in like warm water, slowly flowing along the meridians towards his brain. There was no stinging sensation, only a gentle warmth.
Rin closed his eyes, clearly feeling Geto Suguru's Cursed Energy slowly moving through his brain, like a pair of gentle hands softly stroking every inch of his brain region.
The Cursed Energy nodes related to "Cursed Techniques" were touched one by one, emitting faint resonances, but the areas where traces of Silk Binding Cursed Technique and Cursed Spirit Manipulation should have been remained completely calm, without any fluctuations of Cursed Technique imprints.
Geto Suguru's brow furrowed slightly, and the Cursed Energy at his fingertips slowed down even more as he carefully scanned every corner of the deep brain. In Rin's brain, apart from the Innate Cursed Technique, which should be the Sharingan, other areas were as clean as untouched white paper.
A moment later, Geto Suguru withdrew his hands, and the Cursed Energy in his palms slowly dissipated.
He looked at Rin, a flicker of confusion in his eyes at first, which then turned into a knowing surprise, and his tone was affirmative:
"In your brain, there is only one imprint of an Innate Cursed Technique: the 'Sharingan Cursed Technique'."
"How is that possible?" Rin's eyes snapped open, his voice filled with astonishment. "The Silk Binding Cursed Technique and the Bone Cursed Technique that I copied with the Sharingan... they didn't leave any traces?"
"No." Geto Suguru shook his head, gently tapping his own temple with his fingertip.
"My Cursed Energy can precisely capture the logical traces left by Cursed Techniques in the brain region. During the examination just now, there was no information about any other Cursed Techniques apart from the flow path of the Sharingan Cursed Technique."
He paused, his gaze falling on Rin's eyes, as if he could see the crimson tomoe through the darkness,
"The answer should be in your Sharingan. It can not only copy Cursed Techniques but also has its own independent'storage space', temporarily storing the copied Cursed Technique logic within the eye technique, without directly imprinting it onto the brain."
This statement made Rin completely relax, his tense shoulders slowly loosening.
He raised a hand to touch his eyes. So, these eyes actually hid such a secret; it was simply perfect.
"So now... I can continue to copy other Cursed Techniques without fear of affecting my brain?" Rin asked.
"Theoretically, yes." Geto Suguru smiled and nodded, but his tone became more serious. "But don't be too greedy. The Sharingan can store Cursed Techniques, but your proficiency with them still depends on practice.
To deal with stronger enemies, you still need to repeatedly hone your Cursed Energy manipulation."
"Mr. Geto, what should I train next? Or... should I just copy your Cursed Spirit Manipulation? With the Sharingan, I should be able to remember the core logic."
Geto Suguru, however, shook his head and slowly walked towards him, his black monk robe gleaming softly in the morning light:
"The most important thing now isn't to learn new Cursed Techniques, but to understand your Sharingan. You mentioned before that the Sharingan can purify and evolve by devouring Cursed Spirits, right?" Seeing Rin nod, he continued to press, "So now, how many more Grade 1 Cursed Spirits do you need to devour for it to evolve again?"
"Nine." Rin didn't hesitate, his tone firm. "After devouring that Grade 1 Bone Cursed Spirit before, I could clearly feel the Sharingan evolving towards the Three Tomoe stage.
Based on my perception, I only need to devour nine more Grade 1 Cursed Spirits to evolve to the Three Tomoe."
Geto Suguru's eyes brightened, and he asked again:
"Will new abilities awaken after evolving to Three Tomoe? Such as stronger Insight, or... other special Cursed Techniques?"
Hearing this, Rin gently shook his head, concealing the subsequent information about the Sharingan, his tone tinged with uncertainty:
"I don't know. The Sharingan's evolutionary path is very vague. I can only perceive the number of Cursed Spirits needed; as for what will awaken, I have no clue at all."
Geto Suguru fell silent for a moment, then suddenly raised his hands to form a hand sign. Black Cursed Energy surged in his palms like an inky tide:
"If that's the case, then let the Sharingan evolve to its third form first."
Geto raised his hands to form a hand sign, black Cursed Energy surged in his palms like an inky tide, and the Cursed Energy at his fingertips suddenly erupted outwards. Three cracks appeared on the ground, and black mist spewed forth. Nine Grade 1 Cursed Spirits of various forms emerged one after another; some were covered in hard shells, others dragged long tails, and all were enveloped in violent Cursed Energy.
Just as Rin was about to mobilize his Cursed Energy, Geto Suguru raised a hand to stop him:
"You don't need to do anything."
His figure shifted slightly, and black Cursed Energy, like living chains, instantly wrapped around the armored Cursed Spirit at the front. With a "crack," the shell shattered, and the Cursed Spirit died instantly. Immediately after, the remaining eight Cursed Spirits also failed to last long and were all defeated by Geto Suguru's precise Cursed Energy, turning into nine corpses.
Rin stood aside, already prepared.
He took a deep breath, and his eyes slowly opened, the crimson double tomoe glowing in his eyes like burning flames.
This time, he did not mobilize Cursed Energy to envelop the Cursed Spirits, but directly maximized the Sharingan's absorption ability. Streams of black and red Cursed Energy threads shot out from his eyes, like a dense spiderweb, precisely wrapping around each Cursed Spirit corpse.
As soon as the Cursed Spirit corpses touched the threads, they dissolved at a visible speed, turning into pure Cursed Energy that surged into Rin's body along the threads.
He could clearly feel that the total Cursed Energy of the nine Cursed Spirits was even greater than all the Cursed Spirits he had absorbed at school combined. As soon as it entered his body, it went straight to the Sharingan in his eyes.
When the first Cursed Spirit corpse was absorbed, Rin felt a slight warmth in his eyes. By the time the third one was absorbed, the warmth turned into a faint stinging sensation, and the double tomoe began to slowly rotate in his eyes. When the ninth Cursed Spirit corpse was completely absorbed, the stinging sensation intensified sharply, and the double tomoe spun faster and faster, like rapidly moving gears.
