Above Mary Geoise, ten thousand meters high:
The Blood Sea and the Dark Sea continuously clashed in the sky, and Nox and Imu were also engaged in a fierce confrontation.
Under the control of Nox and Imu, the Blood Sea and the Dark Sea were evenly matched.
However, Imu himself was constantly pushed back by Nox, who unleashed his Limitless Life Enhancement and used his absolutely powerful physical strength.
Initially, Imu relied on his powerful Busoshoku Haki to suppress Nox in his normal state, and later relied on his super-grade Haoshoku Haki to suppress Nox after normal life enhancement.
Now, with his Limitless Life Enhancement activated, Nox was finally able to repel Imu in a head-on collision.
"This state of his is absolutely not sustainable!"
Imu looked at the mighty Nox, and after being repelled by Nox, he regained a sliver of rationality, no longer controlled by anger, and decided to temporarily avoid his edge.
Therefore, when Imu fought Nox afterwards, he did not choose to confront him head-on, but instead chose to fight and retreat, wanting to stall for time.
However, after Nox had been suppressing Imu for half an hour, Imu still did not feel any weakness from Nox.
"Damn it, is it possible that he can maintain this limit state indefinitely?"
Seeing that Nox's power had not weakened at all, Imu continued to stall for another half an hour, but ultimately found that Nox's power had not weakened at all, and had even become slightly stronger than before.
At this point, if he still couldn't figure out what was going on, he would have lived for eight hundred years in vain!
"Hahahahaha, Imu, aren't you the World King? Why are you being so timid and afraid to fight me head-on? Could it be that you are afraid of me because you see that my power is stronger than yours!"
Seeing Imu's state, Nox instantly accelerated and rushed in front of Imu, raising his hand and slashing down at Imu's head with a sword.
"Damn it, is this a type of his Devil Fruit ability? Allowing him to continuously maintain this high-burst form?"
"Could it be that he has some reliance behind him that eliminates all the side effects of that high-burst state?"
Facing Nox's swift sword strike, Imu also gathered all his strength and punched towards it.
However, due to insufficient strength, Imu was still repelled several hundred meters by Nox's sword.
Although this did not cause any injury to Imu, it made him feel extremely uncomfortable internally.
He was a high and mighty god, how could he allow someone to be stronger than him in terms of power?
"Right, reliance, the opponent's reliance must be his Devil Fruit ability, which means that his high-burst state requires reliance on this Blood Sea!"
"As long as this Blood Sea is destroyed, the opponent's reliance can be eliminated, and then the final victory will be mine!"
Instantly, Imu seemed to have found Nox's weakness, staring intently at the Blood Sea beneath Nox's feet.
Just as Imu thought, Nox's weakness was this Blood Sea; without the continuous supply of fresh blood from the Blood Sea, the side effects of his Limitless Life Return could not be eliminated.
"Infinite Devour!!"
Imu roared, and his entire body plunged directly into his Dark Sea, causing the entire Dark Sea to churn and boil violently.
The Dark Sea floated in the air like a sea of clouds, but under Imu's control, the Dark Sea completely compressed, converged, and gathered to form a massive dark sphere, or more accurately, a black hole.
The black hole was like a gluttonous maw with infinite devouring power; everything around it, including air, clouds, breeze, and even light, was completely devoured by this black hole.
After the Dark Sea transformed into a black hole, its devouring power increased exponentially, and even the Blood Sea could not resist the black hole's devour.
The fresh blood in the Blood Sea was like a flood with opened gates, continuously being devoured by the dark sphere.
"Withdraw!!!"
Nox waved his hand and immediately withdrew the Blood Sea, preventing it from approaching the dark sphere and avoiding more fresh blood being devoured by the opponent.
However, Nox wanted to withdraw, but Imu would not let Nox have his way.
The massive black hole flew directly towards the Blood Sea; as long as the black hole could immerse itself in the Blood Sea, it could completely devour all the fresh blood within the Blood Sea!
"Limitless Sword Soul·Blood Dragon Sky Severing Slash!!"
Gathering the power of the Blood Sea onto the sword body, as Nox slashed out with his sword, instantly, infinite sword qi and fresh blood evolved into a ferocious blood dragon slash.
As the blood dragon attacked, the Blood Sea instantly surged, and the ferocious blood dragon slash mercilessly struck the black hole that was coming towards it!
"Rip!!!"
In an instant, the black hole, which was like a black sun, was directly split in two from the very center by the blood dragon slash.
Infinite darkness was completely revealed under the sunlight, but within that black hole, there was only darkness and darkness; Imu's figure was not found in the split black hole!
"Darkness is immortal!"
However, the black hole split open by Nox's sword was connected like a broken lotus root, and was healing at an extremely fast speed.
"It can heal even when split in half, so what if I destroy your entire black hole!"
As the black hole was healing, Nox raised the Seven Star Sword, and countless air currents rushed in, forming a strong swirling vortex in the entire sky that poured into the Seven Star Sword.
"Limitless Sword Soul·Bagguk!!"
When countless air currents, Haki, and the Limitless Sword Soul combined, they transformed into majestic energy, and as the Seven Star Sword slashed out, it instantly blasted out with absolutely invincible power, like a Pluto cannon!"
The originally massive black hole that had merged together was completely enveloped by the super-large range of the Bagguk impact!
"Rumble rumble!!"
The impact wave of the Bagguk instantly crushed the entire black hole with destructive force, turning it into scattered pieces of dark energy in the air.
"Found him!"
Imu, who was originally hidden within the black hole, was exposed to Nox's Kenbunshoku Haki the moment the black hole was destroyed.
"Kill!"
Nox, who had discovered Imu's whereabouts, immediately rushed into the dispersed black hole, charging up a sword strike and mercilessly slashing towards Imu.
Imu rushed over, and he also punched towards him.
However, the moment Imu's fist touched the Seven Star Sword, he instantly felt that the power on the Seven Star Sword was much stronger than before, and his entire body was sent flying several hundred meters by Nox's sword!
"Damn it, my Dark Sea has been defeated!"
It was only as he was flying out that he remembered that it wasn't that Nox's power had become stronger, but that his power had become weaker.
Before, he had the enhancement of the Dark Sea or the black hole, and his power was sublimated; now that the black hole was destroyed by Nox, the power enhancing him naturally weakened, and his strength was indirectly weakened!
"However, you should never have intruded into my domain!"
While Imu was flying backward, he didn't stabilize his body immediately, but instead mobilized his dark power to re-condense the dispersed black hole.
Countless fragments of dark energy were seen rushing rapidly towards Nox, and the originally massive black hole model quickly re-adhered.
"Blood Sea without bounds!"
However, just as the black hole was merging, Nox also mobilized his Blood Sea to rush into the black hole that had not yet fully formed.
A complete black hole would be enough to devour Nox's Blood Sea.
But an incomplete black hole was not enough to suppress Nox's Blood Sea.
When the Blood Sea rushed into the incomplete black hole, the Blood Sea surged violently, constantly impacting the black hole that was trying to merge, causing the black hole to be continuously defeated; even with Imu presiding over it, he could not completely piece the black hole back together unless he could defeat Nox's Blood Sea!
"Bastard!!!"
Seeing this move by Nox, Imu felt extremely uncomfortable!
In his helplessness, Imu could only withdraw all the dark power, wanting to form a new Dark Sea again.
"Slash!!!"
However, Nox would not give Imu this opportunity; while the Blood Sea was destroying the black hole, Nox, holding the Seven Star Sword, once again charged towards Imu, slashing at his head with a sword.
Imu, knowing that his power was inferior to Nox's at this moment, immediately crossed his arms to block above.
"You fell for it!"
Just as Nox's Seven Star Sword was about to slash down, Nox suddenly turned his body, withdrew the Seven Star Sword, and slashed at Imu's chest with another sword.
"I won't fall for it!"
However, at the same time Nox changed his move, Imu also immediately changed his move, quickly withdrawing his fists from above and once again blocking in front of the Seven Star Sword.
"Fake!!!"
However, the moment the Seven Star Sword struck Imu's hands, Imu instantly knew that this Seven Star Sword was fake, because the power on the Seven Star Sword was too weak!
It was at this moment that the real Nox, holding the Seven Star Sword, had already slashed at Imu's abdomen.
"Rip!!!"
The terrifying sword edge immediately tore apart the Busoshoku Haki defense and the dark devour defense on Imu's abdomen; the incredibly sharp sword body directly slashed into Imu's flesh and blood, and the powerful impact once again sent Imu's body flying several hundred meters.
"Damn it, this move again!"
Dark energy surged into the wound on Imu's abdomen, and the injury quickly healed, but his mood was extremely bad.
He had fallen for this move before, and he didn't expect to be hit again now!
Most importantly, that sword strike had injured his soul again!
"Hahahahaha, Imu, your body is rusty; after eight hundred years, you probably haven't even had a normal battle!"
"If you don't have more powerful strength, then wait to be killed by me and give up the throne of World King!"
As Imu was repelled by him, Nox pressed his advantage and immediately pursued him.
Nox found that although Imu's power was very strong, his body's instinctive reaction speed was very slow.
Many times, even if Kenbunshoku Haki cannot perceive danger, the body can perceive danger in advance and make the most effective and instinctive reaction.
This is a kind of intuition, or a sixth sense, or the combat instinct of a strong person.
Just like the dirty tricks Nox used when fighting Imu before, under normal circumstances, even if Imu was tricked by Nox, among equally strong opponents, the body would instinctively avoid the danger of Nox's sword.
Even if he couldn't completely avoid it, he wouldn't take the full damage of Nox's sword squarely; when the body couldn't react, he could reduce the damage of that sword.
But Imu's body instinct was a beat slower, causing him to be completely hit by Nox.
"Bastard!!!"
With his own power inferior to Nox's, and lacking in combat instinct and experience, Imu was beaten back step by step by Nox.
And as the battle continued, Nox's Limitless Sword Soul continuously wounded Imu's soul; although these injuries were shallow, they accumulated.
When Imu fought Joy Boy in the past, he habitually used a fighting style that exchanged injuries.
After all, he himself possessed an immortal body, and even severe injuries could recover, so he was not afraid of being injured.
Therefore, even when facing Joy Boy, he dared to confront him head-on, and Joy Boy often had to retreat from this fighting style of his.
But now, Imu didn't dare to use this fighting style that he was best at, because he knew that Nox's self-healing ability was also terrifying; even if it wasn't an immortal body, it wouldn't be far off.
Most importantly, Nox's Sword Soul could damage his soul, which could be said to be a very effective ability against his immortal body!
"Being able to witness my true power, you can truly die!"
After being suppressed and slashed by Nox for an unknown number of times, reaching the limit of his patience, Imu finally stopped hiding and decided to unleash his most powerful strength!
Imu was seen squeezing his body, suddenly erupting with incredibly powerful force to repel Nox, after which his body began to expand, and his aura continuously surged.
"This is not Life Return!!"
Seeing Imu's figure start to expand, it was very similar to how Nox enhanced himself using Life Return before, but in reality, it was not.
This was a method Imu used, utilizing the power of the Dark Contract, to transfer the power of those who provided him with blood sources from beneath Mary Geoise to himself.
Each of those who could provide him with blood sources was at least a Vice Admiral-level existence, and there were over a hundred of them; almost eighty percent of their power was superimposed on Imu.
This caused Imu's entire physical strength and Haki to expand in a short period of time.
However, once this method was used, it caused great harm to those who provided the blood source, and if Imu was not restrained in the end, it was possible that all those who provided Imu with power would be sucked dry by Imu and die.
It was precisely because the cost of this method was too great that Imu did not intend to use it from the beginning.
But now that Nox had forced him to this point, he had no choice but to use it, otherwise, he would have to use uranus!
Compared to the possibility of completely destroying Mary Geoise and killing almost all the Celestial Dragons after using uranus, he preferred to use this method.
"Power, this is my most powerful strength!!!"
Feeling the constant surge of powerful strength in his body, Imu became excited; this kind of power was too captivating!!
