Bai Sui then discovered that the soul he had replicated was essentially a file Bai Sui had saved, so even if it dissipated Bai Sui, he could recreate it.
However, only one can exist at a time, and Bai Sui also discovered that the soul is actually the same as a person, with its Rhythm changing subtly every moment. Therefore, Bai Sui's recording is really like an archive, which can only save the state at the moment of recording, unless Bai Sui updates its Rhythm, that is, saves a new file.
After recording that first soul, Bai Sui felt as if he had suddenly broken through a window, realizing that he could record not only souls but also people.
The main difference lies in the varying complexity of the individual's Rhythm, which affects the difficulty of recording and the time required.
Taking Land of Kang as an example, the easiest subjects to record are common children. The younger the child, the easier it is to record. Infants are the simplest to record. Although it is not possible to record in seconds yet, it will be soon.
Afterwards, due to their respective growth environment, personal abilities, and so on, the Rhythm become increasingly complex. Take Madara Uchiha as an example. Before he obtained the Rinnegan, it took Bai Sui several days to finally record it. However, after he obtained the Rinnegan, Bai Sui found that the magnificence of his Rhythm had increased significantly. It would probably take Bai Sui at least a year and a half to record it.
Furthermore, after obtaining the Rinnegan, Madara Uchiha's strength changed daily, and his Rhythm was constantly fluctuating. This made it impossible for Bai Sui to record Madara Uchiha after he obtained the Rinnegan.
However, this is not a problem for Bai Sui. After all, even ordinary people couldn't record it before, so he believes that he will find a way to solve this problem sooner or later.
Since Bai Sui was able to record the entire person, his research on Kekkei Genkai became increasingly in-depth. He not only tried to integrate all the known Kekkei Genkai in the Ninja World into himself, but also deduced various Kekkei Genkai that had disappeared or had not yet appeared.
Through Bai Sui's tireless efforts, a total of twenty-seven Kekkei Genkai were successfully incorporated into her body.
Because these twenty-seven Kekkei Genkai inherently contain seven nature transformations—fire, wind, earth, water, thunder, yin, and yang—a miraculous fusion occurred after Bai Sui successfully placed them into her body through Rhythm.
Perhaps because it met certain specific conditions, Bai Sui clearly felt a change in her body, a change from the inside out, or rather, a reorganization.
Because Bai Sui was already Earth Immortal, his life level was a level higher than that of ordinary people. Therefore, he did not experience the changes that occurred when others obtained the Kekkei Mōra in the original work. Instead, he suddenly found that he had an additional form of transformation.
This change, how should I put it, is like your hand; when it's open, it's a palm, and when it's clenched, it's a fist. A fist and a palm are two different forms, but it's still a hand.
Bai Sui felt that she could transform into a horned form like the Otsutsuki, or she could maintain her current form. The choice was entirely up to her, as simple as clenching a fist.
Of course, just as there is a difference between a palm and a fist, the two forms are naturally different as well. At least for Bai Sui now, in the Otsutsuki Form, Bai Sui's combat power is several levels higher. There's no way around it, since Bai Sui originally didn't know any protective techniques, which meant that he could only exert less than Issei of his own strength.
However, Bai Sui has also discovered something: the life level of the Earth Immortal is no lower than that of the Otsutsuki Form. Although he cannot exert much power because of him, everyone is at the same level.
At the same time, Bai Sui also sensed the "wedge" of the Ōtsutsuki Clan.
The Ōtsutsuki Clan can replicate themselves and digitize their own data, then implant it into another person's body. A black diamond-shaped mark will appear on the palm of the person whose body is implanted, which is the "Karma". In fact, the Karma is the Otsutsuki's own body data. The person whose body is implanted can use the Karma's abilities, and the Ōtsutsuki Clan can directly see the degree to which the Karma on the "vessel" has thawed.
Through Bai Sui's perception, it was discovered that this so-called datafication of oneself was actually a disguised way of replicating one's own Rhythm. The so-called ability to see the degree of thawing of the "wedge" was actually just seeing the degree of change in Rhythm.
Perhaps it's because of the difference in their systems. Although both were naturally acquired at this level, Bai Sui's Rhythm sees more and is not limited to himself, while Xie is only limited to copying himself. Of course, this could also be because they don't care about other lives besides themselves.
Thus, Bai Sui not only obtained the Rinnegan and Kekkei Mōra, but also gained the ability to create other Rinnegan and Kekkei Mōra.
Although the Rinnegan and Kekkei Mōra Bai Sui directly bestows upon others lack their respective special abilities and are considered a castrated version, the good thing is that they can be mass-produced.
As for those who want the normal version, judging from the examples of Madara Uchiha and Uchiha Izuna, it would take five to six years at most to train one.
And don't forget that it's not just limited to one person at a time. Although we can't train too many at once due to the need to consume Dharma Power to infuse ocular power, even so, there are still about sixty years until the next batch of the Ōtsutsuki Clan arrives in the Ninja World. How many qualified combatants will be trained during that time?
So, Bai Sui returned to Land of Kang from his Chamber of Secrets. Oh, by the way, in his years of quiet development, Bai Sui has successfully incorporated nearly one-tenth of the entire Ninja World's surface into his Inner Landscape. Although he has not yet achieved the permanent eighteen-fold increase in Dharma Power that Bai Sui envisioned, it is already far from it.
At least for now, the resources within Bai Sui's Inner Landscape are sufficient to sustain Bai Sui's eighteenfold increase in power for a month of combat.
As of now, Bai Sui cannot imagine under what circumstances he could fight at such a high intensity continuously for a month, which is barely perpetual.
The reason why Bai Sui wanted to return to Land of Kang first was because he wanted to replicate the more than twenty Kekkei Genkai Madara Uchiha and Uchiha Izuna. The reason for doing this first was that Bai Sui sensed that his own unique eye technique was being nurtured in his eyes.
During this waiting period, Bai Sui decided to find something to do and also wanted to study the Tenseigan, since the Golden Wheel Reincarnation Explosion was quite cool, wasn't it?
