"Agh~"
A painful roar erupted from Roshi's mouth as his skin was being rapidly eroded by the tailed beast chakra.
At the same time, the tailed beast cloak enveloping him grew thicker and denser.
Not only that, but a tail also appeared behind him.
And as soon as this tail emerged, an oppressive aura far surpassing anything before radiated from him, filling the entire area.
Under the influence of this aura, Roshi's eyes even turned a shade more bloodshot.
Clearly, his will was being eroded by the tailed beast.
Seeing this, Seimei thought to himself, "Almost there, just a little bit more. Can't rush it."
So, he communicated with his two shadow clones, and they continued to work together to pressure Roshi, forcing him to draw out even more tailed beast chakra.
Roshi's consciousness was clearly affected, and he didn't realize that Seimei and his shadow clones were deliberately holding back.
Or perhaps he did notice, but there was nothing he could do about it.
At this stage, he could only draw out more tailed beast chakra in the hope of breaking through the encirclement formed by Seimei and his two shadow clones, thereby escaping his perilous situation.
Therefore, he continued to extract the tailed beast's chakra.
...
Time passed, second by second.
Soon, a second tail appeared behind him.
At this point, the tailed beast chakra surging around him was already occasionally coalescing into the image of the Four-Tails.
Now, if Seimei chose to attack, he would have about a 60-70% chance of capturing the opponent alive.
But he still wasn't in a hurry. Seimei wanted to wait until the opponent manifested a third tail before making his move.
At that point, the success rate would increase to 80-90%, and as long as he wasn't too unlucky and didn't make any major mistakes, he would basically succeed.
However, while he wanted to wait, Roshi didn't want to continue drawing out the Four-Tails' chakra.
He still retained some rationality after all, and he knew that continuing to extract the tailed beast chakra could very likely cause him to completely lose his mind, thereby losing control of his body.
At that point, there was no telling what might happen.
Because of this, he stopped extracting the tailed beast chakra.
This caused the third tail that was about to form behind him to recede.
Upon seeing this, Seimei became anxious. He didn't want the other party to interrupt the process.
So, he immediately ordered his two shadow clones to intensify their attacks on Roshi.
However, with two tails and having entered a semi-tailed beast state, Roshi's strength had greatly increased. Every move he made displayed power far exceeding his previous capabilities.
Molten lava, formed by Lava Release, was being poured out by him as if it cost nothing, forcing Seimei and his two shadow clones to dodge repeatedly.
Even the lake on the ground was rapidly turning into steam and disappearing due to the presence of this lava. Seimei didn't even have time to replenish his chakra.
Seeing the situation developing in an unfavorable direction, Seimei didn't hesitate at all and immediately used his strongest technique – Susanoo!
In an instant, his Mangekyo Sharingan was activated.
Immediately afterward, immense ocular power surged forth, causing his chakra to transform into Yin Release chakra. Around his body, a towering figure materialized out of thin air.
It was a giant at least thirty meters tall, with a completely silver-white body and a pair of enormous wings.
At the same time, a massive longsword hung at its waist.
This longsword wasn't some kind of divine weapon; it was simply a weapon that Seimei materialized simultaneously during the formation of his Susanoo.
However, it was more than enough.
Clang~
The sound of a blade being drawn echoed.
Standing within the head of the Susanoo, Seimei controlled it to draw the longsword from its waist, then with a mighty swing, he slashed down at the semi-tailed beast Roshi below.
All of this happened in the blink of an eye.
Seimei's Mangekyo Sharingan had already evolved to the Eternal Mangekyo Sharingan, so he wasn't afraid of consuming a little ocular power.
Coupled with his vast chakra reserves and powerful physical abilities, he didn't have to endure much pain when materializing the Susanoo.
Thus, the speed was naturally fast.
And because of this, Roshi hadn't even reacted when he launched his sword attack.
By the time he sensed the danger, it was already too late to dodge, and he could only face it head-on.
At the critical moment, he once again unleashed his ninjutsu – Lava Release: Granite!
In the next instant, the lava that was flowing around him immediately converged, forming a thick wall of molten rock, blocking the path between him and Seimei.
However, this sword strike from Seimei's Susanoo possessed power capable of splitting mountains and shattering rocks. A mere wall, even with the enhancement of Lava Release, couldn't possibly stop it.
With a "shick" sound, Seimei's longsword plunged into the lava shield, then rapidly moved forward, quickly slicing it in half before continuing its descent towards Roshi's body.
Seemingly realizing the danger, the Four-Tails began to actively retract its power, no longer influencing Roshi.
Roshi's rationality returned significantly. He didn't have time to worry about the Four-Tails' change in attitude and immediately relied on his years of combat experience to lunge forward, barely avoiding Seimei's sweeping sword.
Then, without any hesitation, he immediately raised his hand to form hand seals and unleashed his most proficient and powerful ninjutsu at this stage against the massive figure in front of him – Lava Release: Scorching Stream Rock Technique!
In the next moment, a large amount of lava was spewed out by him, transforming into numerous giant magma balls that rained down like scattering flowers upon various parts of the Susanoo.
However, Seimei completely ignored these attacks.
He simply took a slight step to the side and then swung his sword again, aiming for Roshi.
Having learned from the previous experience, Roshi didn't dare to directly confront the attack and immediately chose to sidestep.
Seeing this, Seimei didn't hesitate at all and immediately swung his sword again.
And Roshi continued to dodge.
Just like that, back and forth, the two engaged in combat.
But Seimei's longsword was too massive. Often, a single strike would cover a large area, coupled with his swordsmanship skills.
Initially, Roshi could still dodge and counterattack, but soon, he could only dodge.
Then, even dodging became fraught with danger.
Out of desperation, he had no choice but to risk continuing to extract the Four-Tails' chakra, further enhancing his combat power.
Originally, he thought he would immediately be subjected to the tailed beast's will.
However, even after he manifested the fourth tail, the Four-Tails didn't actively try to seize his consciousness. Instead, it even manipulated the tailed beast chakra to intentionally cooperate with his actions.
Roshi felt that if this synchronization lasted a little longer, he might be able to perfectly adapt to and master the tailed beast chakra.
However, he was destined to not have that opportunity.
Originally, Seimei could have made his move when the opponent manifested the third tail, but seeing the other party engrossed in the battle, Seimei simply gave him enough time to manifest the fourth tail.
Now, making his move, he was completely confident.
Therefore...
"Alright, let's begin!"
Seimei muttered to himself, looking down at Roshi.
"What?"
Roshi asked, confused.
In the next moment, his gaze met Seimei's, who was inside the Susanoo.
Instantly, a massive Sharingan filled his vision.
This Sharingan was like a black sun, radiating an irresistible aura.
Gradually, Roshi fell into unconsciousness.
At the same time, the Four-Tails within him was also invaded by the Sharingan's power and fell into a genjutsu.
Indeed, a Jinchuriki with the cooperation of their tailed beast can largely resist the effects of genjutsu, but that's on the premise that the tailed beast itself isn't affected.
If even the tailed beast is affected, then they can only be manipulated like Yagura Karatachi in the memories.
