"Being stared at by four pairs of eyes like that… I wonder what it would feel like."
Shinji shook his head with a wry smile.
He figured that if he, unaware, encountered such a 'Susanoo', he'd likely be startled.
After confirming that the power of 'Susanoo Tomoshibi' had grown stronger, a sudden idea struck Shinji. He pulled out Karin's pair of 'Rinnegan' and Yakumo's pair of 'Koryugan', which he carried with him.
Taking these two high-quality dojutsu Bloodline Limits from their small nutrient containers, Shinji activated 'Susanoo Tomoshibi' and completed their mastery.
In an instant.
Karin's 'Rinnegan' entered the second pair of eye sockets, while Yakumo's 'Koryugan' filled the third.
The moment the mastery was complete, Shinji felt a surge of energy.
"My dojutsu power has increased again!"
Shinji paced to the mirror on one side of the training ground.
His 'Six-Tomoe Rinnegan' was superior to an ordinary Rinnegan, so this mastery, aligning with 'Susanoo Tomoshibi's' principle of the strong dominating the weak, almost perfectly extracted the dojutsu power of the 'Rinnegan' and 'Koryugan'.
This naturally led to an increase in dojutsu power and the mastery of their techniques.
Shinji couldn't quantify the boost, but he estimated it to be around 20%.
Considering his already immense dojutsu power with the 'Six-Tomoe Rinnegan', a 20% increase was an absolutely staggering absolute gain.
At the same time, he noticed in the mirror that his 'Six-Tomoe Rinnegan', after mastering the 'Rinnegan' and 'Koryugan', seemed to have undergone a subtle change in color—from its initial pale purple to a deeper, vibrant purple.
At first, he thought this was a temporary change due to dojutsu power overflow. But as his dojutsu power stabilized and his chakra fully settled, the vibrant purple hue remained, confirming that his 'Six-Tomoe Rinnegan' had undergone some unknown transformation after mastering the additional 'Rinnegan' and 'Koryugan'.
Propping his chin, Shinji pondered.
The vibrant purple of his pupils was clearly not a stable state; it seemed more like a transitional phase from the original pale purple toward a crimson hue.
"Could mastering more dojutsu cause my Rinnegan to turn red?"
It seemed that with Kaguya Otsutsuki's bloodline, when dojutsu power reached its peak, the Rinnegan would evolve into a crimson hue akin to the Sharingan. Both Kaguya Otsutsuki and Madara Uchiha, after activating Infinite Tsukuyomi, had red Tomoe Rinnegan at their foreheads.
"There's still one pair of empty eye sockets. If I master Neji and Kimimaro's Tenseigan as well, my 'Six-Tomoe Rinnegan' might undergo further changes!"
Shinji's thoughts began to wander.
He suddenly realized that after his Rinnegan became the 'Six-Tomoe Rinnegan', enhancing 'Susanoo Tomoshibi's' power further, a new path to strength had opened before him.
Mastery!
He had a faint feeling that by mastering more and stronger dojutsu Bloodline Limits, his dojutsu power could break through some kind of limit.
This realization set him ablaze with excitement.
Having long been overshadowed by the fear of the Hegemon of Terror, he finally felt a spark of confidence in defeating the Hegemon!
"Come to think of it, I owe a lot to Mumei!"
Shinji sighed.
Without Mumei, the dojutsu 'Jikibi', 'Wazunagi', and 'Susanoo Tomoshibi' would likely have been lost or buried deep within his spiritual form, unusable.
It was Mumei's 'Yachihoko' that granted him the 'Six-Tomoe Rinnegan' and the combined abilities of the Rinnegan and Eternal Mangekyo Sharingan.
Looking back, Mumei had helped him cross a threshold that ordinary shinobi could scarcely imagine!
Without crossing it, Shinji might have ended up like the First Hokage or pre-revival Madara Uchiha—reaching Super Kage-level strength, dominating the shinobi world and overpowering Kage-level opponents, but still fundamentally mortal, bound by the cycle of birth, aging, sickness, and death, never touching the Six Paths level.
Having crossed that threshold, his paths to the 'Six Paths level' had multiplied.
The Ten-Tails, once his only option, was now just one of many.
Using Mumei's 'Yachihoko' to unleash a small-scale 'Infinite Tsukuyomi' to gather the shinobi world's chakra, or leveraging the enhanced 'Susanoo Tomoshibi' to master more and stronger dojutsu for a qualitative leap through quantitative accumulation—both were now viable options for Shinji.
Next, Shinji activated 'Jikibi' and 'Wazunagi'.
As expected, their abilities had also been greatly enhanced, perhaps because he had simultaneously activated 'Susanoo Tomoshibi'. He even sensed a subtle connection, suggesting he could use 'Susanoo Tomoshibi's' fusion ability to attempt merging 'Jikibi' and 'Wazunagi' into one.
Shinji suppressed the urge to merge them immediately.
First, having just awakened the 'Six-Tomoe Rinnegan', his chakra hadn't fully stabilized, and his control over his dojutsu power wasn't yet refined.
Second, 'Jikibi' and 'Wazunagi' were very similar to 'Yachihoko'. Merging them could produce unpredictable results, so caution was necessary.
With a smile, Shinji thought to himself, "Before, I could only passively wait for Akatsuki to revive the Ten-Tails. Now, with the 'Six-Tomoe Rinnegan', I'm going to be busy again."
His lips curled upward at the thought.
He wasn't one to passively await fate. If he could push for a higher realm before the Hegemon's arrival, he'd rather toil and fight for it!
"Mumei won't be able to use her Sharingan for a while, but I can arrange a First Hokage cell transplant to boost her physique, speeding up her Sharingan's recovery while enhancing her dojutsu power!"
"For mastering dojutsu Bloodline Limits, I already have one pair of Rinnegan, one pair of Koryugan, and a dormant pair of Tenseigan—three pairs ready! Once Neji and Kimimaro have nurtured their Tenseigan, I can try mastering them!"
"The Ten-Tails is still necessary, so it's time to meet Orochimaru. If he can release the Fourth Hokage sealed in the Reaper's stomach, we won't need to extract the Nine-Tails from Naruto's body."
Shinji mentally organized his plans, feeling there were things to do again.
