This is the heavenly bird with a bounty of one billion.

"Monster... It's my fault..."
"Run... hurry and run..."
"Even Boss Jinbe is no match for him..."
"How could this be, how could this be..." Kneeling on the ground with her hands covering her face, tears continuously slipped through her fingers. At this moment, Shyarly was filled with powerlessness and despair.
"I will never let you destroy Fish-Man Island." High in the sky, Jinbe appeared beneath the giant spear, his entire body surging with power. He had to stop it, he had to...
"Then try and stop me." Like a deity, Xuanye coldly looked down at Jinbe from above, his eyes devoid of the slightest pity. He reached out and pointed from afar. In an instant, the sky tore open, and a giant spear of fire plummeted downward.
"Fish-Man Karate, Secret Technique: Vagabond Drill."
Soaring into the sky, Jinbe's hands were enveloped by swirling water, his Armament Haki flickering. With all his strength surging throughout his body, an impeccable shockwave that incinerated everything erupted from the ground up.
"Boom..."
The entire firmament exploded. A hurricane crushed downward, causing Fish-Man Island to tremble slightly. On the ground, an invisible force directly tore through the rock, forming a terrifying spiderweb-like crater spanning ten thousand meters.
"Puff..." Amidst rolling rubble, a figure heavily collapsed to the ground, breathing weakly, his entire body stained crimson with blood.
"This is powerlessness. You lack the strength to protect what you hold dear. In this world, weakness is a sin." Landing lightly before the crater, Xuanye looked down coldly at Jinbe within it and said indifferently.
"The most pathetic thing is that the weak don't even have the self-awareness of being weak. That's why you fish-men have become ugly creatures looked down upon by humans."
"Even without power, I will still protect Fish-Man Island." Spitting out a mouthful of blood mixed with flesh, Jinbe shakily stood up and looked firmly at Xuanye.
"I admire your willpower. Unfortunately, you courted death by angering me, so... Fish-Man Island will be destroyed." Flames erupted and the earth turned crimson, transforming into scorching liquid in the blink of an eye.
"You can't do this! I was the one who angered you—if you want to kill someone, kill me alone! What does this have to do with the others?" With an agitated expression, Jinbe clutched his chest, his eyes fixed dead on Xuanye.
"Destruction, does it need a reason?" The corners of his mouth curled up as a ferocious aura burst forth. This devilish voice filled Jinbe with utter despair.
"You lunatic! I won't let you succeed. Even if I die, I will stop you." Roaring aloud, Jinbe couldn't believe that the guy in front of him used to be a Marine. How could this possibly be a Marine? He was completely a lunatic, a lunatic who slaughtered the innocent indiscriminately.

"Then let me see your power!" Highly amused, Xuanye calmly looked at Jinbe.
"Whoosh..." His figure vanished. Jinbe appeared behind Xuanye and lashed out with a kick that seemed to carry the power of the ocean.
"Too slow." His figure flashing, Xuanye appeared behind Jinbe and launched a fierce counter-kick.
"Boom..." The ground cracked, and Jinbe was sent flying backward.
"Compared to Kizaru's speed, you're practically a snail." A chilling voice rang out. Jinbe's pupils dilated as he saw Xuanye descending from the sky, ruthlessly stamping his foot down and driving Jinbe straight into the earth.
The ground fractured, countless fissures spreading outward, revealing Jinbe lying helpless among the rubble, covered in blood.
He was no match. Completely no match. The two sides were simply not on the same level.
"How could he be this strong..." In the distance, Arlong clenched his fists tightly, whispering in disbelief.
On Fish-Man Island, Brother Jinbe's strength could be said to be the absolute strongest. Yet in the hands of this human, there was simply no comparison. Could this kind of power truly belong to a human?
At this moment, the surrounding fish-men who continuously swarmed upward all wore expressions of terror. The human at the center of the battle was far too terrifying; he was simply a monster.
"I deeply empathize with this unwillingness of yours. Isn't it deeply despairing?" Standing beside Jinbe, Xuanye stood straight, looking at the fish-men in the distance who were observing him cautiously. He lowered his head and said mercilessly, "This is the world of the survival of the fittest. Once upon a time, I felt just as despairing as you. Therefore, I swore that for the rest of my life, I would only bring despair to others, and to that end, I would use any means necessary, even destroying the world."
"Is it hard to understand this mindset? You probably think I'm a lunatic, right? That's right, I am a lunatic, and all of this was forced upon me by others—time and time again, crushing my hopes. I hate this world, I hate everything in it. Therefore, you are very unfortunate to have provoked such a lunatic."
"No... you can't do this... They are all innocent." Struggling and dripping with blood, Jinbe reached out and grabbed Xuanye's ankle tightly.
"Look, your pathetic begging hasn't won their understanding. Even now, they still fail to recognize reality. How pathetic is that?" Expressionless, Xuanye's face exuded a chilling frost.
Struggling to turn his head, Jinbe's face was covered in blood as he looked in disbelief at the fish-men once again closing in around them.
"L-Let go of Boss Jinbe... You damned human." With pale lips, even though trembling with fear, fish-men still brandished their weapons and stepped closer, one pace at a time.
"Damned demon, get out of Fish-Man Island! You are not welcome here."
"We fish-men are the greatest race..."
"Let go of Jinbe... Lowly human..."
"Y-You guys... Hurry and run... The person before you is not someone you can handle." Weeping and shouting, Jinbe roared.
"Lord Heavenly God Bird, please spare Fish-Man Island, I beg you..." At this moment, Shyarly knelt on the ground, weeping and pleading.
"Ignorant, and full of courage, yet utterly conceited. You still dare to threaten me—is it because there are more of you?" Disdainful as he looked at the vast sea of various fish-men surrounding him, Xuanye let out a cold snort. For this race that viewed themselves with grandeur, Xuanye felt not the slightest bit of fondness.
In fact, at this very moment, the hostility in his heart was already weighing whether or not to truly destroy this island.
"Stop right there." At that moment, a majestic voice rang out. On the horizon, countless royal soldiers appeared, led in the very front by four figures—one large and three small.
"The King! It's King Neptune, along with the three princes and Princess Shirahoshi! We're saved."
"This human is dead for sure. With countless royal soldiers here, he has nowhere to run."
"Kill him! Make him wish he were dead, and let him repent in hell for the fish-men."
"A mere human dares to act wildly on Fish-Man Island. He's courting death."
Filled with fervent enthusiasm, the surrounding fish-men were all overjoyed at the sight of Neptune, completely unaware that this kingdom no longer possessed any powerhouses. This had to be called the ignorance and tragedy of the fish-men.
The crowd parted as squads of royal soldiers, guarding Neptune, appeared before Xuanye.
"I do not know how Fish-Man Island has offended Lord Heavenly God Bird, who possesses a bounty of one billion, that you would so savagely slaughter my subjects." At the head, Neptune looked with a heartbroken expression at the corpses littering the ground. Temporarily suppressing the fury in his heart, he said through gritted teeth.
