When they walked out of Orochimaru's research complex, three days had passed since they entered.
After all, it was a massive facility, and Orochimaru's interesting research was indeed more captivating to Sora than the world's changes.
Sora didn't really care much about the world anyway.
Changing the world was just something he felt he should do as a Transmigrator.
These things were decent as a pastime, but Sora wasn't truly invested.
So, after touring the new world, Sora returned to his magnificent Soul King Palace.
And then... began a long period of seclusion!
Yes, seclusion!
Seclusion is a term usually used in Cultivation Novels, meaning cultivators spend a long time training, often for decades or centuries, to understand the difference between mortals and immortals.
Generally, someone like Sora wouldn't need seclusion, but he was doing it now.
Because Sora needed to contemplate his future development.
A very serious matter was that Sora's strength hadn't increased for quite some time.
Although he had absorbed the Soul King before, that was just a minor enhancement.
To put it in perspective, Sora had increased his quantity but not his quality.
Even though his current quality was already absurdly high, it still wasn't enough.
Compared to those legendary immortals, Sora was still lacking.
Because all his current power was just raw strength… he hadn't touched upon legendary concepts like authority or rules.
And as for Sora's pure power, he estimated it was roughly at a planet-destroying level.
Planet-destroying level was also the maximum combat power that worlds like the Ninja World and Soul Society could produce.
After all, Soul Society was just a small world, and the Ninja World wasn't much bigger.
That's why Sora needed to think about his power level.
Even being the Soul King didn't change that. So what if he's now a Soul King? The Soul King wasn't immortal. A spirit body was more stable than a physical body, but it only slowed aging.
Currently, Sora's power was based solely on Reishi.
"So, how do I get stronger from here?" Sora pondered.
"Should I gather the power of Naruto World as well, master Truth-Seeking Balls, master Dojutsu?"
"Feasible methods, not difficult for me, but seems unnecessary."
"My Reishi is pure… I lack neither quantity nor quality. I don't need to incorporate complex systems."
"But there is one thing I can play with."
Sora turned his wrist.
Two golden eyeballs appeared in his hand.
These were the two Tenseigan from the Moon's Otsutsuki, specifically from the Moon in his world.
Sora directly compressed them down to normal eye size.
Personally, Sora felt the Tenseigan was somewhat stronger than the Rinnegan, though not as versatile.
But Sora didn't need the Rinnegan's versatility. As mentioned, he didn't need overly complex systems.
So Sora planned to refine and absorb the Tenseigan, integrating it into his own system.
Fortunately, this wasn't difficult.
With the Tenseigan readily available, and his current power far surpassing the Tenseigan's level, he just needed to add its methods.
This absorption was simply like acquiring a new weapon.
Thus, Sora quickly finished absorbing the Tenseigan.
After a brief period of adjustment, Sora opened his eyes.
A pair of pure white eyes with a cosmic glimmer opened!
Sora quietly observed the new world, enjoying the 24K high-definition clarity, and seeing things like gravity, space, and even time materialize before his eyes that were previously invisible.
Sora was somewhat amazed: "Is this the world seen through the Tenseigan?"
Of course, Sora knew this wasn't simply the view from the Tenseigan. The Tenseigan could use these powers, but it didn't mean it could see them.
Being able to see them now wasn't because the Tenseigan was strong, but because Sora was strong.
Nevertheless, Sora was satisfied.
Why did so many machines pursue visualization?
Wasn't it because for humans, visualization is the most intuitive and comfortable way to operate?
The difference between counter-intuitive and intuitive operation was significant.
With these eyes, Sora also had ideas for his future growth.
He had now reached a certain level in both volume and quality.
However, his left hand's Shinigami techniques were a bit weak for his current level, after all, they were mortal techniques, not divine techniques.
Moreover, Sora was a pure Reishi Aggregate, and Reishi as a fundamental unit had its limits.
Well then, he would treat himself as a celestial body.
