Yubi was excited because he felt this battle was full of challenges!
It was a test from this world to verify if he was qualified to exist.
As for the madness... it stemmed from survival instincts. Influenced by the frantic secretion of adrenaline, he had to start facing and enjoying the pressure and pleasure brought by this battle.
No matter what, he couldn't fall here.
He had even more reasons why he couldn't die... His plan hadn't succeeded yet!
If he could survive, Yubi even had a premonition... his soul would receive a grand baptism!
...Yes... he had been 'one-shotted'.
But he didn't die instantly.
Instead, he was slowly stepping toward a state of death... As long as he didn't become a corpse, he still had time to change everything.
Although his positive experience points were exhausted, the negative experience points he had been accumulating hadn't been used yet... In his last moments of consciousness, Yubi used the system to exchange for a second ability besides the character Belphegor.
And this time, the experience cost was a full 1,200 points.
It was his entire 'income' for a month from killing Amegakure on the border of the Land of Rain.
After this ability was assimilated by the system into the power system of the Ninja World, it was fundamentally different from the former... because it wasn't a type of Ninjutsu.
It was a Bloodline Limit!
It was related to medical treatment... it was blood.
This power was used for killing people, not saving them.
It came from the Kamo clan's technique in Jujutsu Kaisen, the Scarlet Blood Manipulation Technique.
It can be understood as a means of 'controlling' blood to produce changes and power, manipulating objects with blood.
Blade Intent Manipulation was only an A-rank Ninjutsu... costing 200 points. The price of Scarlet Blood Manipulation Technique was six times that of the former.
Although the system had a premium in this regard and the cost-performance ratio wasn't as high as the categories related to saving people, for Yubi, it was already his entire fortune.
Scarlet Blood Manipulation Technique... became a Bloodline Limit ability.
It could be driven... without the need for hand seals.
Therefore, while he was on the ground, Yubi immediately controlled the blood flow inside and outside his body. Using the effect after system assimilation, he kept the blood circulating normally throughout his body and maintained his life state at the minimum level... Then, he treated himself through Medical Ninjutsu.
The Bloodline Limit of Scarlet Blood Manipulation Technique... could transform Chakra into blood and use it.
As long as his Chakra wasn't exhausted, this Bloodline Limit could be activated indefinitely.
But this ability of his didn't come from the character Choso in Jujutsu Kaisen, so his blood didn't contain lethal poison.
If he wanted that kind of effect, he could purchase it later.
However, Yubi thought... it was already enough... Still the same swiftness... Still the same terrifying speed... In an instant, the Konoha Jonin who was originally nearly thirty meters away arrived in front of him.
The Kunai in his hand was wrapped in Chakra... With that extended arm and chilling momentum, he stabbed directly at Yubi's face.
Judging from the boy's expression, he still couldn't catch his trajectory.
Only... as soon as he got close to the opponent, Otani noticed something unusual.
A dragging force suddenly came from his legs.
Looking down, he found that the pool of blood flowing from the boy on the ground had actually turned into two large hand shapes, wrapping around his feet.
These two masses of wriggling blood were like gelatinous substances, and their binding force was astonishing.
Clang!
During this pause, the Konoha Jonin sensed danger and swung his hand to shatter a flying knife with his Chakra Kunai.
It was the boy's bizarre Ninjutsu that used silk threads to control flying knives.
But with his perception, he could dodge or block it.
However, the blood on his legs, in the blink of an eye... like a living thing, was spreading toward his upper body.
Otani was startled. Immediately, with the enhancement of Chakra, he erupted with powerful physical strength, broke free from those two masses of blood, and retreated by jumping away.
"What Ninjutsu is this?"
"No... there were no hand seals. It's different from that Ninjutsu used to control flying knives."
"Is this... some kind of Bloodline Limit?!"
While Otani pulled back to a safe distance, his mind raced as he observed.
He had never heard of this kind of Bloodline Limit.
What kind of power was it exactly?
Did the Hidden Sand Village still have such combat resource reserves?
While he was thinking, he saw the boy a few meters away... open his palm.
A few drops of blood rose up.
They emitted an eerie luster.
Swoosh, swoosh, swoosh... Immediately after he landed, the blood droplets shot out at an extremely exaggerated speed.
They drew several red lines in the air.
"This speed and power!"
Otani's expression changed drastically. Just by hearing the sharp whistle of the blood droplets piercing the air, he could analyze the destructiveness of this move.
The facts were just as he judged.
He tried his best to dodge the first two blood droplets, but at the third one, a bloodstain was cut onto his forehead as he tilted it away.
It was right below his forehead protector.
Suddenly, the blood flowing from his forehead poured into his eye socket.
"It seems that like other Bloodline Limits, although I have this power, I still have to continue to develop and change it in the future... Currently, it's only the first stage, and the level isn't very high." Yubi's heart stirred upon seeing this.
No wonder... the price wasn't that ridiculous.
As for to what extent this Bloodline Limit could be used and what kind of power it could explode with, in the future... it would depend on his ability.
At this time, two black shadows also took the opportunity to fly down beside the Konoha Jonin, sandwiching him from left and right.
The two puppets controlled by Sasori, Father and Mother, raised their arms at the same time, revealing two sharp long swords, and slashed over from different angles.
In the gap of parrying, Otani noticed... on the boy with a smile in the distance, blood droplets were slowly rising from his hand again.
"No matter what power it is... I'm afraid it will be difficult for me to get close again for a while. This boy is standing in a pool of blood. As long as I step into that area, I will be interfered with by that blood power. It's very much like a defensive Ninjutsu."
"Although it's a bit scary... judging from his fighting style and the situation where I just broke free from those two masses of blood, I can still deal with it."
"The problem is... his long-range attack method, regardless of speed, power, or accuracy, makes it impossible for me to easily strike at the other red-haired boy who is a Puppeteer."
"Even if I force a move, I probably won't be able to take down either of them in a short time."
"These two brats are intentionally stalling for time..."
"This is troublesome!"
While Otani was fighting with the two puppets that were entangling him, his gaze subconsciously glanced in the direction he and his companion had come from, thinking, "Have Shikaku and the other three... not arrived yet?"
Boom!
Suddenly, from another part of the battlefield in the distance, there was a commotion.
A large number of scattered wind sickles erupted; it was the Wind Release Ninjutsu performed by Arai.
The three people here all heard someone groan in pain.
Clearly, the Konoha Jonin fighting Arai was injured.
This caused Otani, who was still fighting, to change his expression.
Even among Jonin, there were gaps in strength.
After all, Arai was an Elite Jōnin serving as a Kage Guard. In a one-on-one situation, it was difficult for Ryosuke to hold out for too long.
Moreover, the opponent also knew the situation of these two boys and would definitely spare no effort to strike a killing blow and end the battle quickly.
Otani couldn't help but change his mind.
He wanted to retreat with his companion; he couldn't fight to the death.
He especially couldn't let Ryosuke be sacrificed... Thinking this, he tightened his grip on the Chakra Kunai in his hand and used a special Taijutsu move.
Under the swing of his arm, three spots of light inexplicably lit up on the puppet 'Father'.
The shell, which was far more solid than other puppets, was like being hit by a thrown boulder. Where the spots of light lit up, the outer shell immediately cracked and was covered with fine lines.
It was pushed away by the sudden burst of momentum.
And Otani took advantage of the space created by the retreating puppet to jump away.
He prepared to ditch Yubi and Sasori to support his companion... and deal with Arai.
Then find a way to escape.
Just as he started to move, a fist descended from the sky.
The person swinging the fist was exactly Arai, who had quickly moved over to this side.
Otani was caught off guard by Arai's appearance. After being hit heavily, his figure staggered and he spat out blood.
"This guy didn't kill Ryosuke... instead, after confirming the battle situation was stable, he came to protect these two brats first!" Otani's eyes were nearly splitting as he realized this.
And at this very instant.
He heard the familiar sound of breaking air by his ear.
It was that high-speed ejecting blood droplet with shocking power!
Swoosh!
In the next second, the blood pierced through this Konoha Jonin's temple like a bullet.
With Arai's help... Yubi, who delivered the finishing blow, completed a beautiful execution and harvest.
"It's him..."
Otani's body fell toward the ground.
In a daze, he seemed to see the boy standing in the distance who had made the move to kill him.
His final thought wasn't unwillingness or anger.
As a Ninja, he had long been prepared to sacrifice himself for the Village on the battlefield.
He was just... after personally experiencing the stunning performance of these two brats, starting to worry about Konoha's... next generation.
Especially... this brat who could control blood, he was too dangerous!
