When Bai Sui teleported back to the Grand Tutor's mansion, he saw Kushina and her husband Namikaze Minato cuddling together.
They had someone refill their tea and prepared some extra pastries for them. After chatting for a while, they saw Senju Hashirama arrive with his granddaughter and grandson-in-law.
"Hello, Auntie! Hello, Son-in-law!" Kushina quickly stood up to greet the visitors.
It was thanks to the unification of the Ninja World that Uzumaki Mito, who had married out of the family, was prepared to never see her loved ones again before she died when she learned that her husband had chosen to support the Feudal Lord and her clan had chosen to establish a country.
Unexpectedly, within just ten years, earth-shattering changes occurred. The entire Ninja World was unified, Senju was able to reconcile with Uzumaki, and she was able to reunite with her family.
Moreover, she became a member of the royal family. After unification, in order to recognize the contributions of the Land of Kang, the King of Kang was not abolished. Although King of Kang no longer had real power, he remained a symbol of status.
Seeing that the others had arrived, Bai Sui began to busy herself, dividing the life energy in her hands into four parts, giving them to Kushina Tsunade, and the child in their wombs.
With Bai Sui's help, they absorbed all the life energy in about half an hour, and then they could proceed with the prenatal care and wait for delivery.
During their subsequent conversation, the group mentioned Tsunade's husband Dan Katō. The two had also met at the Hongwen Hall, as the Ninja World had been at peace for a long time and there was virtually no opportunity for war.
The reason Dan Katō didn't come along was because he was currently on the Starship. After all, his family's Spirit Transformation Technique contained unique methods for cultivating the soul, which made it easier for him to separate the Primordial Spiritual Energy compared to others.
Speaking of Dan Katō, Bai Sui is reminded of Jiraiya, he was a star character in the Hokage storyline in her previous life, and his tragic end makes him unforgettable.
Tsunade was naturally aware of this guy who often leered at her, and even complained, "I don't know what Mount Myoboku was thinking, that it would want to give Summoning Scroll to such a lecherous guy. You know, he was caught trying to peep into the women's bathhouse many times back in school."
It's easy to tell from Tsunade's tone that she's unhappy with Jiraiya, probably because he's been trying to spy on her.
That makes sense. There are no three of them in the current Ninja World. Sarutobi Hiruzen is not their master. Although his mastery of all chakra natures made him a well-known elite teacher at the Hongwen Hall, it was impossible for Tsunade to become his apprentice, since his grandfather was still alive.
Without the experience and interaction of growing up together, who would like a guy who dresses greasy and is always trying to spy on others? Once Bai Sui understood this, she stopped asking questions. After all, although Jiraiya had lost a love, at least he wouldn't be beaten to death by his own student. And judging from Tsunade's tone, it seemed that this guy was living a carefree and extravagant life every day.
After seeing the others off, Bai Sui sat cross-legged in the void, taking stock of his gains over the years. Among them, the most important to Bai Sui was his achievement of becoming Yang Spirit.
As the saying goes, gold is immortal, hence it is a treasure of all things. When the three gates of essence, qi, and spirit are perfected, the Golden Core that naturally gathers and condenses contains the secret of human immortality. When Bai Sui's Primordial Spirit completely absorbs and reconstructs it, all the yin energy dissipates, and the yang energy is naturally generated. At this moment, Bai Sui's Yang Spirit has finally succeeded.
Of course, Bai Sui now has two choices. One is to abandon his physical body and exist only as Yang Spirit. In this way, he can be carefree and happy in space, soaring thousands of miles, treading on clouds, looking down at mountains and seas, or playing in the human world, changing in a thousand ways, and doing whatever he wants.
However, if things continue like this, there may be no possibility of going any further. Although Bai Sui was already satisfied with this, this world is not peaceful. Who knows what kind of methods the God of Otsutsuki possesses, or even if there are other, more powerful beings in this universe?
After all, for such a tiny planet like Earth to encounter the biggest boss in the entire universe before even stepping outside is a bit too incredible. Therefore, Bai Sui guessed that perhaps the Ōtsutsuki Clan wasn't the main point, since compared to the universe, what Bai Sui knew was far too limited.
Therefore, Bai Sui has now chosen the second path, which is to continue to refine the Yang Spirit on this basis. Every day, he returns the Yang Spirit to the Ancestral Aperture and refines it again and again with his own true fire in order to refine the spirit and return to emptiness. The Yang Spirit becomes spiritual after a hundred refinements. The wisdom light of the Yang Spirit generates divine fire, which penetrates all the apertures of the body. The Yang flames soar into the sky, penetrating from the feet to the top of the head, and the body is refined into the Yang Spirit, so that the divine light shines everywhere.
Finally, after refining the body into divine fire, the body disintegrates and shatters into innate primordial energy that is neither existent nor nonexistent, formless and traceless, returning to the void and achieving oneness with heaven and man. When the skill reaches this point, it can gather into form and disperse into energy, surviving calamities and living as long as heaven and earth.
Now, Bai Sui is following this method, cooking it with pure fire every day. Over the decades, the Yang Spirit has not changed at all, but the vertical pupil that carries the Yang Spirit has shown an unusual phenomenon.
The entire eye resembled a dazzling, seven-colored glass, shimmering with a soft glow like fireflies. All the pupil power, Dharma Power, and natural energy were absorbed under the tempering of the true fire.
However, it still did not develop any special eye techniques like the Rinnegan, as if it were just an ordinary eye. But Bai Sui knew that it was definitely not, because over the years, the various energies absorbed by this vertical pupil were several times or even dozens of times more than those Rinnegan.
The energy consumed by this single vertical pupil is several times greater than the combined energy of Bai Sui's Rinnegan, Tenseigan, and Jōgan. Although it has not shown any significant abilities so far, Bai Sui has high expectations for its future.
Oh, by the way, Bai Sui's Rinnegan has now evolved further than before, into a red three- Tomoe Rinnegan. This Issei was made possible after the Research Institute analyzed the Ten-Tails.
Based on the information provided by Otsutsuki Hagoromo and his brother, Otsutsuki Kaguya, they deduced that all the different types of Rinne Sharingan were variations of Byakugan Byakugan, and they also discovered the violent and chaotic spiritual energy of the Ten-Tails.
Many speculate that the fruit Otsutsuki Kaguya devoured contained a large amount of the Ten-Tails ' negative emotions and spiritual power, and that these negative emotions were the source of the Sharingan. The Rinne Sharingan, in particular, was the product of a qualitative change resulting from the accumulation of even more massive negative emotions.
This also explains to some extent why Otsutsuki Kaguya became increasingly brutal in their eyes later on; she was gradually influenced by these negative emotions, and her whole being was sliding towards the abyss.
So Bai Sui put this theory into practice. Relying on the fact that he had already achieved the Yang Spirit status, Bai Sui directly gathered a large amount of negative emotions, condensed them into spiritual energy, and poured them into the Rinnegan. As a result, the originally white Rinnegan turned red, and then one day three Tomoe suddenly appeared.
Afterwards, Bai Sui wanted to continue infusing negative emotions, but a bad premonition arose from the bottom of his heart. His Yang Spirit was warning him that if he continued to let the Rinnegan infuse negative emotions, his Yang Spirit would not be directly polluted.
But it's like a fly that keeps buzzing around your ear. It can't hurt you, but it definitely attracts your attention, and over time it might even upset you and make you feel annoyed.
These negative emotions are like that; although they won't actually affect Bai Sui Bai Sui, they're like flies buzzing around her.
Normally, we would ignore them, but once the Bai Sui itself shows any abnormality, just like when someone is in a bad mood due to something, these flying insects will have a particularly strong impact on their mood.
Therefore, Bai Sui stopped there and remained in the state of the three- Tomoe Rinnegan. In this state, Bai Sui's eye techniques underwent a slight change.
The original Mangekyo eye technique still exists, and its effect has even improved. However, it is now used more roughly, lacking the subtlety and gentleness of its predecessor.
Next comes the eye techniques of the Rinnegan. In addition to the most basic gravitational and repulsive forces, two other eye techniques were born in Bai Sui's Rinnegan: Huan and Nang.
The original meaning of Huan is the royal domain, referring to the area within a thousand miles of the ancient emperor's capital. The ability here is to open a different dimension completely under Bai Sui's control through her pupil technique. This is different from the Inner Landscape. The things in the Inner Landscape are based on reality and are places that others can directly reach. However, this different dimension belongs exclusively to Bai Sui. Outsiders cannot enter without Bai Sui's permission, and forcibly entering will only destroy it.
The original meaning of "" is before, before, and in the past. Here, Bai Sui is given the ability to rewind the time of things in his sight. Although Bai Sui can also do it in disguise through the inscription of rhythm, the premise is that Bai Sui must have inscribed the opponent when he was young. This pupil technique has no such restrictions. As long as Bai Sui has enough magic power, it can be used directly.
This is the Rinnegan. Based on the theories from the Research Institute, Bai Sui also tried to infuse a large amount of Natural Energy into the Byakugan, and sure enough, he activated the Tenseigan, a special eye technique different from the Rinnegan.
The Tenseigan primarily enhances the control over energy. In addition to basic attraction and repulsion, the Tenseigan can condense an energy ball that is a mixture of spiritual power and Natural Energy. Once this energy ball is injected into someone else's body, it can control that person's body and mind to a certain extent.
Due to the suppressive effect of Natural Energy on the Primordial Spiritual Energy of chakra, this spiritual energy ball is particularly effective against ninjas, but it is temporarily ineffective against the Ōtsutsuki Clan. This was demonstrated through experiments on Ōtsutsuki Isshiki, though it is possible that he was residing in someone else's body at the time.
It can be said that the greatest function of the Tenseigan is to enhance the user's ability to control various energies. As for the Golden/ Silver Wheel Reincarnation Explosion, it is a form change and burst of the Truth-Seeking Orb.
Beyond that, Bai Sui made further attempts, injecting other types of energy into the Byakugan. Among them, physical energy had a very good effect, resulting in the creation of a pair of Jōgan.
The Jōgan's eyeballs are light blue, and its conjunctiva is black. Unlike the White Byakugan, it doesn't bulge veins when it opens its eyes. It possesses the basic farsightedness of the Byakugan, but while the Byakugan sees things in black and white, the Jōgan sees things in color. In addition, it can directly see spatial fluctuations. Combined with Bai Sui's ability to see Rhythm, this directly elevates Bai Sui's understanding of space to a new level.
However, while these three pairs of eyes are good, they cannot coexist. Although Bai Sui could have grown more eyes, it would be too ridiculous.
So Bai Sui has been trying to figure out how to fuse these eyes together, or combine various abilities, since they are all based on the changes in the Byakugan.
Finally, after decades of unremitting efforts, Bai Sui managed to fuse these three types of eyes together through his own Rhythm.
The merged eyes looked completely different, with black conjunctiva, blue irises, and concentric rings of cyclical lines, the innermost ring featuring three Tomoe rotating in a circle.
The most significant improvement of these merged eyes is the enhancement of all their abilities, including their ability to manipulate gravity and repulsion, as well as their control over spacetime.
For example, Madara used the Tengai Shinsei before, and if Bai Sui were to use it at full power now, it could directly attract a meteorite with a diameter of more than ten kilometers, which could easily destroy the ecosystem of the Ninja World. Although, if Bai Sui really wanted to destroy the ecosystem, it could do so with just a thought now.
Even more noticeable is Bai Sui's pupil technique, the unique alternate dimension that belongs to Bai Sui. Not only has its size greatly increased, but its stability has also been significantly improved, and a large amount of Natural Energy has appeared within it.
The most crucial point is that this Natural Energy wasn't infused by Bai Sui; it was generated naturally! What does this mean? It means that Bai Sui will have endless energy from now on. Although the generation rate of this Natural Energy seems somewhat slow now, as long as construction continues, sooner or later Bai Sui will have inexhaustible energy.
After thinking for a long time, Bai Sui decided to just call these fused eyes the Rinnegan, since the name wouldn't affect their abilities anyway.
Bai Sui began his daily cultivation in his Grand Tutor's mansion, hoping to reach the point where he could gather into form and disperse into energy, survive calamities, and live as long as heaven and earth. At that time, he would have truly stepped into the threshold of the Great Freedom.
He could refuse whenever he wanted, and he wouldn't have to worry about any danger to his life. But unexpectedly, while Bai Sui was meditating, a picture suddenly appeared in his mind: a starry sky with two travelers on their way.
