That night, after returning home, Yubi summoned the System, preparing to enhance his abilities.
His positive experience points weren't many, just over a thousand.
As for negative experience points, he had accumulated over four thousand, three thousand of which were the reward for killing the Third Kazekage.
Without the Third Kazekage's "contribution," his savings wouldn't be so rich.
Over the past few years, he had been busy with the Village's industrial issues. Although he used the Bounty Station to operate outside the Village for a while and later went to the Land of Rain, the targets he assassinated and the enemies he encountered were relatively weak—resulting in no bonuses to his negative experience points.
The only benefit was that they brought him a fairly substantial financial income.
Kurenai-gan: A Dojutsu-type Bloodline Limit, hailed as the natural enemy of the Byakugan. It can see through objects and perceive energy.
It can sense danger and use Chakra to create images to interfere with reconnaissance, possessing superior capabilities to the Byakugan in observing Chakra. (From the character Ranmaru)"
Ketsuryugan: A Dojutsu-type Bloodline Limit originating from the Chinoike Clan. This Dojutsu is awakened through strong emotional stimulation. Its visual power can rival a standard Sharingan. It appears as a horizontal bar-shaped black pupil with blood-red sclera, accompanied by bleeding from the eyes and hair standing on end when activated. It has a "hypnotic" effect in the field of Genjutsu, can turn targets into "human bombs," and can perform various Ninjutsu through blood. (From the character Chino)"
Yubi had long since set his sights on his new ability choices.
It was precisely these two types of Dojutsu. Firstly, they could compensate for his shortcomings and enhance his perception.
Secondly, he could use the Yin Power inherent in Dojutsu Bloodline Limits to augment his mental strength and master Yin Release Chakra.
Kurenai-gan was included in the System because of its X-ray vision effect.
The Ketsuryugan, like the Scarlet Blood Manipulation Technique, was related to blood.
In fact, among the System's "merchandise," there were many abilities related to X-ray vision, such as the X-ray superpower from a certain character in Academy City that Yubi had looked through before, as well as eye-related abilities with an "absolute control" effect—none of which belonged to the power System of the Naruto world.
But some of those required positive experience points to purchase.
There were very few Dojutsu that could be bought with negative experience points and were included in the System.
The reason Yubi favored these two Dojutsu was that buying other similar abilities, even if assimilated, might not necessarily enhance his mental strength or come with Yin Release.
Whereas these two Dojutsu from this world would definitely cause his Chakra nature to change.
In this way, he would essentially have four types of Chakra transformations: Yin Release, Yang Release, Water nature, and Earth nature.
Another point was—looking at the original work, it wasn't hard to see that any Bloodline Limit related to Dojutsu seemed to be traceable back to the two characters Indra and Ashura.
Especially the Chinoike Clan, who possessed the Ketsuryugan; it was highly likely they had a slight connection to Indra.
As such, after Yubi obtained this power—he wondered if it would cause his own Bloodline to undergo some changes as well.
Regardless of whether it was Indra or Ashura, as long as he could leech a bit of the Bloodline inheritance from these two sons of the Sage of Six Paths, it was a win!
Furthermore—it wasn't hard to see from the Byakugan and Sharingan that Dojutsu possessed the "possibility of evolution."
Although there were no such settings for Kurenai-gan and the Ketsuryugan in the original work, it didn't mean it was absolutely impossible. It was enough that such an "evolutionary channel" existed within the power System; Yubi could later use some of the System's power to explore it himself.
So, considering a series of factors, Yubi had long since set his heart on these two Bloodline Dojutsu.
In fact, in the catalog of items purchasable with negative experience points, there were also the Byakugan and Sharingan. After all, their abilities overlapped to some extent with Kurenai-gan and the Ketsuryugan. Since those two Dojutsu could be included in the System, then the Byakugan and Sharingan naturally were as well.
"It's just that—the potential for the Byakugan and Sharingan to be developed is too great. The Byakugan can fuse and evolve into the Tenseigan, and the Sharingan can evolve into the Mangekyo Sharingan and the Eternal Mangekyo Sharingan. If transplanted and equipped—fusing the cells of both the Indra and Ashura Bloodlines—it's even possible to awaken the Rinnegan."
"Therefore, the prices for the Byakugan and Sharingan are too high—"
"On the contrary, Kurenai-gan and the Ketsuryugan have no subsequent evolutionary settings, so they are very cost-effective—but that doesn't mean there is no possibility of evolution—"
Yubi carefully looked at the descriptions and notes for these two Dojutsu.
What he needed to do now was simply fill the gaps in his perception and Genjutsu while strengthening his mental power.
As for other things—he wouldn't consider them for now.
Anyway, this Ninja World War should be enough for him to harvest a massive wave of experience points.
Furthermore—even if he could buy the Byakugan and Sharingan, he would have to think twice before redeeming them.
After all, these two Dojutsu weren't like the methods he had purchased before, which had never been seen in the Ninja World and could be easily explained away.
The Byakugan and Sharingan were representative of Konoha's combat power—if he suddenly possessed these two Dojutsu, there would be no way to explain it.
It was very likely he would be treated as a "spy" by the Village.
If Konoha heard of such a thing—it was estimated that the Uchiha and Hyuga families would also be stunned.
One must know that at this current point in time—the Byakugan had not yet "leaked" to the outside world, and had not been obtained and transplanted by Ao of the Hidden Mist.
From a strategic perspective, if he, a person from the Hidden Sand Village, suddenly possessed the Byakugan and Sharingan—it would also make Konoha target him at all costs.
This was no longer just a matter involving the Uchiha and Hyuga Clans.
Perhaps even that old ghost Madara would come looking for him.
Yubi's goal was still quite clear.
It was to rise during this Ninja World War—as long as he was given the power he needed, there was no need to pursue things so meticulously, nor did he want to cause too much trouble.
The price for Kurenai-gan and the Ketsuryugan was the same, with no distinction in strength; both were 2000.
And unlike the Scarlet Blood Manipulation Technique, they could not be configured with subsequent power templates.
After all, they both came from the original movie or side stories—the effects and settings of their abilities were relatively singular, unlike the Scarlet Blood Manipulation Technique which had a large number of technique expansions and descriptions.
"This also means that once redeemed—if I want the two Dojutsu to evolve, I can only rely on other powers from the System to catalyze them, or—rely on the power System of the existing world to explore and promote them myself." Yubi pondered.
In the end, he purchased them without hesitation.
System: Congratulations to the host for obtaining the Dojutsu-type Bloodline Limits: Kurenai-gan and Ketsuryugan—would you like to spend experience points to fuse these two similar powers?
"Fuse."
He didn't expect the System's prompt; it seemed to be a pleasant surprise.
Yubi immediately responded with his thoughts.
Ding! The two powers have been fused and successfully assimilated!
The moment the voice sounded, Yubi's eyes underwent a change.
His eyeballs were stained with a layer of blood-red, and some patterns emerged in the black pupils.
Almost the instant the Dojutsu power was generated, Yubi immediately realized that his perception began to spread to the surroundings in the form of mental extension.
And very quickly, through X-ray vision, he captured a Sunagakure shinobi jumping and running on the roof of a building several hundred meters away from his house in the night.
The target he perceived was clearly a member of the Village Guard Corps.
Yubi stood up from the bed and looked in a mirror.
In the mirror, his eyes were already crimson, but several golden spots had appeared in the pupils.
"Phew—good—"
Seeing this, Yubi breathed a sigh of relief.
Although the Fusion of the two Dojutsu didn't seem to have any peculiar bonus effects, it at least changed the original awakened appearance of the two Bloodline Limits.
Kurenai-gan and the Ketsuryugan were, after all, powers from this world; it wouldn't be easy to explain if someone recognized them.
With this change, he could say—it was a natural Awakening after his Blood Release power grew stronger.
With Blood Release as a foundation, plus the fact that these eyes had never been seen in the Ninja World.
The source could not be traced.
It was only logical.
It saved him the trouble of trying to figure out how to fabricate a story.
"Hiss—the effect—is a bit impressive; no wonder the three great Dojutsu of this world are so freakish—looking at it now, it's not just those few types of eyes that are freakish, but all Dojutsu are not simple—" Yubi put down the mirror, his gaze piercing through the wall of his house, looking out into the world.
He said with some amazement.
