Uchiha Kagami knew some of Fumori Masaki's secrets and understood that the power Fumori Masaki possessed was the legendary Sage Power.
Of course, out of caution regarding the secrets of others' power, he didn't know the full extent of Sage Power, only that it was related to the elusive natural energy.
Ever since the Dragon Vein became a significant matter for Konoha Village, Uchiha Kagami, who was involved, had learned a few things.
Fumori Masaki planned to use the Dragon Vein's nature, which lies between natural energy and chakra, to research a jutsu or ninja tool that could convert natural energy into chakra.
He also intended to lower the learning requirements for his Sage Power so that others could also learn it.
It must be said that Uchiha Kagami was still somewhat envious of the miraculous power of natural energy.
Sage Power was equivalent to an advanced stage of chakra training, and the distinction between the two was the ability to effectively use natural energy.
As a ninja, one always hopes to become stronger.
Previously, due to the ninja world's tradition of not prying into others' secrets, Uchiha Kagami naturally wouldn't ask.
However, since Fumori Masaki intended to emulate the previous Hokage by making the learning conditions for Sage Power more accessible—the First and Second Hokage's jutsu belonged to the village's public domain, managed by the higher-ups, and everyone in the higher echelons could learn them; if those below had merits and met the conditions, they could also learn—Uchiha Kagami had to admit that he also wanted to strive for it.
Since the mission to capture the jinchuriki was related to this, Uchiha Kagami pondered for a moment and decided to go all out.
He then said, "Which one should I choose? I am only one person; I cannot capture two simultaneously, unless they are delivered to me together.
Otherwise, after controlling one, the other might become cautious."
"Hmm, about that," Fumori Masaki considered for a moment and said, "Let's choose Rōshi.
He's a rather troublesome individual."
Although he said this, Fumori Masaki's main reason for choosing him was that in later generations, Rōshi was the jinchuriki who had a falling out with Ōnoki and left.
Being able to fall out with an old stubborn man like Ōnoki proved two things: on one hand, Rōshi's resolve was firm, and on the other hand, his ideology differed from Ōnoki's.
Fumori Masaki repeatedly tried to persuade Ōnoki, but he couldn't guarantee whether Ōnoki would accept and change his views.
Although Ōnoki underwent some changes during the Fourth Great Ninja War, just in case, Fumori Masaki still planned to secure his position by capturing Rōshi and thoroughly indoctrinating him.
"A user of the Lava Release kekkei genkai?" Uchiha Kagami meticulously examined the individual's profile.
According to the information, Rōshi should be a close to mid-range ninja, skilled in using Lava Release to cover his entire body, forming a Lava Release armor similar to the Lightning Release Armor, or officially known as "Lava Release Chakra Mode."
In this state, Rōshi's entire body temperature was extremely high, making it impossible for ordinary people to approach him.
Furthermore, Rōshi could use mid-range Lava Release attacks.
With the powerful strength of his kekkei genkai, coupled with the convenience brought by the tailed beast chakra, Rōshi possessed the ability to single-handedly take on a thousand on the battlefield.
Although formidable, for Uchiha Kagami, who possessed the Mangekyo Sharingan, it was truly nothing.
Ordinary genjutsu was ineffective against jinchuriki, but the Sharingan, as a kekkei genkai intimately related to the God Tree from which tailed beasts originated, had a significant loophole in this regard that could be exploited.
Of course, not just any Sharingan would do.
A normal Sharingan could at most deter a jinchuriki.
Only a Mangekyo Sharingan possessed the powerful ability to exploit this loophole and subdue a tailed beast.
With Madara's example before him, Uchiha Kagami felt that he wouldn't have any problems.
"I will guard against Ōnoki's movements, you deal with Rōshi, and the other jinchuriki, Han, will be left to Sakumo," Fumori Masaki said.
"Have a little more faith in your disciple.
Although I don't know how strong Han is, I am very clear about Sakumo's abilities," Uchiha Kagami chuckled.
"Moreover, his coordination with Asuna and Mizuki is excellent.
With the combined power of the three, even a jinchuriki would retreat, wouldn't they?"
"That's true, but it's better to be careful.
Don't praise them too much; it would be troublesome if they became careless.
You can neither withhold praise nor give only praise.
Keep them vigilant at all times, so they won't lose to their opponents in battle due to carelessness," Fumori Masaki said with a smile.
"Alright, that makes sense.
Anyway, with Sakumo there, I'm very confident in Asuna and Mizuki's safety," Uchiha Kagami shrugged.
"Honestly, if I could, I'd want to recruit Sakumo as my son-in-law.
Such a talent is extremely rare."
"He is the only son of the Hatake family.
His father hopes day and night that Sakumo can take on the important responsibility of carrying on the family legacy, so how could he choose to be adopted into another family?
Or are you saying you're willing to marry Mizuki off?
Although your family has gained a son, it wouldn't matter if Mizuki left, but whether your family can accept that is still an issue," Fumori Masaki said upon hearing this.
Traditionally, kekkei genkai families prioritized bloodlines.
To ensure the inheritance of the kekkei genkai, established kekkei genkai families generally practiced endogamy.
The Hyūga clan, for example, strictly adhered to this principle, never allowing the introduction of outside bloodlines.
It's unclear if it's because the kekkei genkai itself alters the bloodline, but the diseases often caused by consanguineous marriage in his previous life never appeared in kekkei genkai families.
In fact, consanguineous marriage was a guarantee for purifying the bloodline and ensuring its strength.
It took Fumori Masaki a long time to accept the unique characteristics of kekkei genkai families.
The ninja world, in some aspects, truly couldn't be understood using common sense from his previous life.
The Uchiha clan was a bit more lenient in this regard; they didn't strictly require endogamy.
However, women who married in, needless to say, would certainly join their husband's family.
As for women from the clan who married out, their husbands had to be adopted into the Uchiha clan.
Only then would they be accepted as a part of the family, and the inheritance of the bloodline would remain under the family's control from beginning to end.
Fumori Masaki had always intended to change this situation because it created too strong a personal dependency on the clan, which could easily lead to fragmentation.
However, even by using other means to attract kekkei genkai families, the inheritance of bloodlines remained an unavoidable hurdle.
This is because the bloodline of a kekkei genkai family is not just about so-called family honor, but also a guarantee of power inheritance.
Even from Konoha Village's own perspective, if they married someone from within the village, it would be fine, but marrying outside would result in a loss of power, which is absolutely unacceptable.
Fumori Masaki considered a method: to apply a certain jutsu to women who married out, which could block the inheritance of the kekkei genkai.
The women who married out would still possess the power of the kekkei genkai, but their offspring would not be able to inherit it.
Since they had the resolve to leave the family's protection, they should also have the resolve to lose their power.
In this world, everything comes at a price; absolute fairness is absolute unfairness.
Fumori Masaki believed that this should be a way for kekkei genkai families to accept women marrying out.
Of course, the key was still to change the prevailing societal atmosphere.
If kekkei genkai families still had a barrier with the outside world, then marrying out would be out of the question.
If even marrying out is not allowed, then a kekkei genkai family cannot hope to escape the traditional clan's control over individuals.
While marrying out does not necessarily mean a kekkei genkai family will be free from personal control, it does signify an atmosphere of openness within the family.
"Indeed," Uchiha Kagami thought for a moment, then gave a wry smile.
Even the clan head couldn't act completely arbitrarily, especially since the bloodline was the guarantee of a kekkei genkai; it wasn't something to be easily shaken.
"Moreover, whether Mizuki likes it or not—"
