Shinji, who was always the one asking others if they were ready, found himself being asked instead. He couldn't help but chuckle. "Yes, let's begin!"
Mumei nodded and started channeling her dojutsu power.
The chakra absorbed from Karin and the others was of high quality, but since it came from different individuals, she needed to use 'Yachihoko' to fuse it together before converting it into dojutsu power capable of transferring techniques to Shinji.
Thanks to the enhanced 'Yachihoko', the entire process took only a second or two. Mumei then unleashed 'Yachihoko' toward Shinji.
Rumble!
Like a thunderstrike, an overwhelming surge of chakra flooded into Shinji's body.
Shinji spread his arms, looking down at his body, murmuring to himself, "How… how is this possible?!"
After awakening his 'Rinnegan' and passing the adaptation period, his dojutsu power growth had gradually slowed.
Even by actively channeling the Yin Release chakra and Yang Release chakra within him to merge and create the 'All Creation Power', his dojutsu power improvement was minimal.
At his current level, while the 'All Creation Power' could still enhance his strength, its efficiency had dropped significantly. Months, or even a year of intense training, might not yield noticeable progress.
Yet, after being struck by the chakra surge from Mumei's 'Yachihoko', Shinji felt his chakra rapidly growing stronger!
At first, he thought it was an illusion.
He assumed the sheer volume of chakra flooding into him was overwhelming his senses, creating the perception of growth.
But soon, he realized that while his chakra volume was indeed surging, its intensity was also rising rapidly.
The increase in chakra intensity directly translated to an elevation in dojutsu power.
In the moment Shinji was stunned, three inky-black tomoe swiftly appeared on the spiral patterns of his pale purple 'Rinnegan'.
Earlier, to calm his subordinates, he had Mumei infuse 'Jikibi' into him, but since the dojutsu power transferred was minimal, no tomoe had appeared.
Now, three distinct inky-black tomoe materialized on the spiral patterns of Shinji's Rinnegan, transforming it once again into a 'Tomoe Rinnegan'.
A few breaths later, Shinji snapped out of his daze, thinking to himself, "I hope this time the dojutsu can be permanently fixed in my Rinnegan!"
Although Mumei could repeatedly infuse 'Jikibi', 'Wazunagi', and 'Susanoo Tomoshibi'—the three dojutsu stored in their crystals—into Shinji using 'Yachihoko', temporary infusions were inconvenient. Moreover, temporary dojutsu only reached the level of the Mangekyo Sharingan, which no longer met Shinji's needs.
At that moment, Shinji suddenly noticed Mumei across from him, with two streams of blood tears flowing from her Sharingan!
"!?"
Shinji was shocked.
Mumei's eye sockets held a pair of Eternal Mangekyo Sharingan, which, under normal circumstances with sufficient dojutsu power, should not shed blood tears.
Unless…
"She's severely overexerting her dojutsu power!"
Shinji instantly understood.
But as he tried to call out to stop Mumei, an even stronger chakra surge struck him, causing his body to float. Completely losing control, enveloped by the immense chakra, he couldn't even make a sound. He could only watch helplessly as Mumei continued to unleash 'Yachihoko', transferring dojutsu to him!
"Are you insane? Stop! Even the Eternal Mangekyo Sharingan can't withstand endless overexertion!"
Shinji wanted to shout, but the chakra surge enveloping him silenced his voice.
"Ah!"
At that moment, Mumei let out a heart-wrenching roar.
With her roar, the output frequency of her 'Yachihoko' reached a new level. The normally invisible chakra transfer channel, overwhelmed by the sheer volume of chakra, began to overflow, emitting a vivid red glow that bathed the dim underground training ground in a crimson hue!
As the recipient of the chakra surge, Shinji felt his body was on the verge of bursting.
The immense chakra was rapidly compressed, becoming fuel to further elevate his chakra intensity.
As his chakra intensity continued to climb, Shinji's dojutsu power visibly surged at an astonishing rate.
On the spiral patterns of his 'Three-Tomoe Rinnegan', three additional, faintly colored but clearly distinguishable tomoe appeared.
Sensing the anomaly, Shinji quickly glanced at the mirror on the training ground's wall, noticing the three new tomoe on his Tomoe Rinnegan. He exclaimed, "Six-Tomoe Rinnegan!?"
In the original timeline, Sasuke, gifted with the 'Yin Power' from the Sage of the Six Paths, had only awakened a single 'Six-Tomoe Rinnegan'.
The power bestowed by the Sage of the Six Paths was undoubtedly at the 'Six Paths level'.
In other words, the 'Six-Tomoe Rinnegan' was on the cusp of the 'Six Paths level', distinctly different from an ordinary 'Rinnegan'.
"Just a bit more, just a bit more!"
Mumei murmured, her face already streaked with blood tears.
Seeing this, a thought flashed through Shinji's mind. The three outer tomoe on his Rinnegan weren't fully stabilized yet. If Mumei pushed just a little harder, he might truly possess a genuine 'Six-Tomoe Rinnegan'.
But he quickly dismissed the idea, shouting with all his might, "Mumei, don't push yourself! Stop now!"
Mumei's eyes had lost their earlier brilliance, staring blankly in Shinji's direction as if out of focus. "Shinji, it's just a little more!"
Shinji shouted, "I know, I know! Stop! If you keep going, you'll destroy your Sharingan!"
"No, I can't let you down! I promised you, and I'll make it happen!"
With that, Mumei squeezed out every last bit of her dojutsu power, pushing 'Yachihoko' to its absolute limit.
Boom!
With a deafening roar, Shinji was blasted backward by the immense chakra surge, crashing heavily into the training ground's wall.
In an instant, the red glow vanished, and the roar subsided.
The underground training ground returned to its dim, quiet state, filled only with Shinji's heavy breathing.
Moments later, as Shinji climbed to his feet, he instinctively glanced at the mirror on the wall. There, he saw six distinct tomoe clearly etched on the spiral patterns of his Rinnegan.
