After spending over a month in the alternate dimension with Kaguya, Shishou finally managed to convince her to consider the bigger picture, urging her to know when to hold back and not act impulsively anymore.
Following this, Shishou took Kaguya to the Land of Ancestors, where they took control of the current Daimyō, restoring the marital life they had once shared a thousand years ago.
With Kaguya pacified, Shishou finally had the time to thoroughly examine the changes that came with achieving the Bloodline Limit: Complete Form.
Just like a thousand years ago, Shishou lay alongside Kaguya on a reclining chair in the courtyard, beginning his introspection.
First, he examined his Genesis Space (始球空间). Unlike Kaguya, who possessed five different dimensions, Shishou's Genesis Space consisted of a single alternate dimension.
However, Shishou's space was many times larger than Kaguya's and had a unique ability.
He could now absorb entire planets into his alternate dimension. With his current power, he could contain two planets within his space. As his strength increased, the number of planets he could contain would also grow.
In addition, Shishou had gained the ability to use Infinite Tsukuyomi and God: Tree World Birth.
He also shared Kaguya's Natural Unity ability, allowing him to freely control the natural environment within his dimension.
However, he did not acquire Kaguya's techniques such as All-Killing Ash Bones, Expansive Truth-Seeking Ball, or Yomotsu Hirasaka.
All-Killing Ash Bones, Rabbit Hair Needle, and Expansive Truth-Seeking Ball were specific to Kaguya's Bloodline Limit abilities, and thus Shishou did not possess them.
Yomotsu Hirasaka was a space-time ability unique to the Ōtsutsuki clan, which Shishou also did not have. However, since he now possessed the Bloodline Limit: Complete Form, he could learn these abilities from Kaguya—though the cost might be steep.
Meanwhile, his Takamikazuchi ability had also undergone a qualitative transformation.
Now, he could effortlessly enlarge living beings or objects as he desired, and he could also accelerate or pause the growth of living organisms at will.
As long as he had enough chakra, he could even make the Divine Tree bear fruit instantaneously.
This ability allowed him to truly control the growth of all things, marking the beginning of his dominion, akin to the legendary Takamikazuchi deity.
After understanding his abilities, Shishou began merging his two Kamui Rinnegan into one.
The technique of merging the Rinnegan into one was something Kaguya had taught him—a unique skill of the Ōtsutsuki clan.
Once the two Kamui Rinnegan were merged, Shishou removed them and implanted Shisui's Kotoamatsukami Mangekyō Sharingan into his eyes, using the power of the Divine Tree within him to awaken them into the Rinnegan.
If Kamui was the strongest physical defense, then Kotoamatsukami was the strongest mental offense.
Shishou was eager to see whether Shisui's Kotoamatsukami ability could control a Six Paths level individual once it evolved into the Rinnegan.
As he channeled the Divine Tree's power into the Kotoamatsukami Sharingan, the eyes pulsed like a heartbeat.
A few minutes later, the pulsation ceased, and Shishou obtained the Kotoamatsukami Rinnegan.
Then, he used the eye fusion technique to merge the two Kotoamatsukami Rinnegan into one, placing it in his right eye.
Next, he placed the single Kamui Rinnegan into his left eye.
He closed his eyes to feel the state of his new eyes, satisfied with the results.
Left eye Rinnegan Kamui, right eye Rinnegan Kotoamatsukami, and the Nine Tomoe Rinne Sharingan on his forehead.
This setup was practically invincible!
"Time to test out the power of Kotoamatsukami," Shishou thought excitedly, glancing at Kaguya lying beside him.
"Kaguya," Shishou called softly as he sat up.
"Hmm?" Kaguya turned to look at him.
Seizing the moment, Shishou activated the Rinnegan Kotoamatsukami, casting an illusion on Kaguya.
For a brief second, Kaguya's gaze turned blank before she quickly snapped out of it.
"Stop fooling around," Kaguya muttered, turning away again.
Seeing this, Shishou nodded in satisfaction.
The Rinnegan Kotoamatsukami had managed to make Kaguya, a Bloodline Limit: Complete Form user, lose focus for a second, proving its immense power.
If used with proper preparation, controlling an unsuspecting Six Paths level individual should be possible.
If upgraded to the Nine Tomoe Rinne Sharingan level, it might even be able to control a Bloodline Limit: Complete Form user.
"Tsk, tsk, this Kotoamatsukami is truly a monstrous ability!" Shishou thought, lying back down to chat casually with Kaguya.
When Shishou casually mentioned his new Genesis Space ability, Kaguya was stunned.
"Did you say your alternate dimension can hold entire planets?" Kaguya asked, sitting up halfway, her expression filled with disbelief.
Seeing her reaction, Shishou chuckled and playfully pinched her cheek, "Is that so surprising?"
Kaguya stared at Shishou with all three of her eyes, as if he were a priceless treasure she wanted to devour.
It wasn't common for someone to gain an alternate dimension like the Genesis Space after reaching the Bloodline Limit: Complete Form.
Even among the many Bloodline Limit: Complete Form users in the Ōtsutsuki clan, Kaguya was a rare case with her five different dimensions.
But Shishou's Genesis Space, which could contain planets, was something Kaguya had never even heard of.
One reason Kaguya had chosen to betray the Ōtsutsuki clan, besides not wanting to be sacrificed, was that the life energy on the Ninja World was incredibly rich. It could allow her to bear a second and third Chakra Fruit, making it a rare treasure in the eyes of the Ōtsutsuki clan.
For this, she had even erased all the markers she and Isshiki had left upon arrival to prevent other Ōtsutsuki members from coming to steal it.
But if she had Shishou's ability, she could have simply absorbed the Ninja World into her alternate dimension, then escaped to another part of the universe, finding other life-bearing planets while slowly growing the Divine Tree. This would greatly speed up the process of producing Chakra Fruits.
And she would no longer fear the pursuit of the Ōtsutsuki clan, always able to escape whenever necessary.
Moreover, Kaguya believed Shishou's ability had great potential and could be even more useful in the future.
Combined with his Takamikazuchi ability to accelerate the Divine Tree's growth...
Kaguya's gaze toward Shishou began to burn with passion.
"This is my man!!!" she thought.
Seeing her expression, Shishou suddenly felt a bit uneasy.
But before he could escape, Kaguya pinned him down, and his mouth was sealed with hers.
The roles had reversed—he was no longer in control.
