"Received, Merlin, Escanor, Kakarot, Jiro, Saitama, Namikaze Minato."
After receiving six cards instantly, Caesar took a deep breath and activated unlimited firepower mode.
Sun that never sets, rise!
Super Saiyan 4 mode, on!
Unblocking mode, on!
Six Paths Sage Mode, on!
Saitama, serious mode, on!
In full swing, an extremely terrifying magic storm instantly swept across the entire beach, blowing all Fairy Tail members away.
"Ur, Gray, build a big ship for the Black Dragon! Ultear, make sure the ship isn't damaged!"
Caesar commanded.
"Wendy, add the dragon-slaying attribute to everyone. Wait until I take him down, then you can come up!"
As he spoke, Caesar disappeared from the spot.
"Everyone, prepare for action!"
At Makarov's call, Ur and Gray rushed to the beach.
"Shaping magic, big ship!"
The two worked together and created an ice boat a hundred meters long on the sea.
The ice boat fell onto the water and swayed with the waves.
Natsu looked and instantly felt dizzy and uncomfortable.
If he was like this, what about the Black Dragon, Acnologia?
Just as Fairy Tail was getting ready, Caesar suddenly appeared in front of Acnologia.
"Roar!"
Without speaking, Acnologia released a dragon breath, blasting toward Caesar.
"The roar of the God-Slaying Dragon!"
Caesar used his ultimate power close to the opponent.
With infinite magic power supporting him, he roared for hundreds of meters, drowning out Acnologia's roar and causing the dragon to fall straight down.
"Boom!"
"The Arc of Time... can't hold on!!!"
Ultear tried to keep the ice ship intact using the Arc of Time, but facing Caesar's ruthless attack, she could barely hold it.
It was enough to hold for three seconds.
The black dragon that fell onto the ice boat was dizzy and unable to stand.
Three seconds was enough.
"Dragon Slayer Secret Technique Modified? Red Lotus Exploding Thunder Blade!"
"The secret of slaying dragons? Karma Demon? Iron God Sword!"
"The secret of destroying dragons? Shining Through? Piercing the sky!"
"The secret of killing dragons? Ming Yu Lei!"
"The secret of dragon slaying? Dimensional Cutting!"
At this moment, the five dragon-slaying techniques, ignoring consumption, bombarded Acnologia simultaneously.
But it wasn't over yet.
"Destroy evil and reveal righteousness in one day!"
"Heavenly Wheel·The Sword of Chaos!"
"Seven Star Sword!"
"Super Cruel Flash!"
After Wendy added the dragon-slayer attribute, countless attacks hit Acnologia.
"Kana!"
"Learn!"
"Gather! The river of light that guides the fairies! Shine! To destroy the minions of evil! The light of the fairies!"
The blow Caesar put in with all his strength hit Acnologia hard.
"Puff!"
Ultear didn't know if Acnologia could withstand it.
She spat out blood, and the Arc of Time could no longer sustain the attack.
The dizzy Acnologia fell into the sea.
Once his dizziness subsided, he flapped his wings violently and returned to the sky.
The combined full-force attack left scars of varying sizes on his body.
Acnologia looked miserable.
"Everyone, lend me your magic power!"
Wendy stood and attached all the guild members' magic to Caesar.
"All have to die!"
At this moment, Acnologia spoke in human language.
He suddenly blew dragon breath toward everyone on Sirius Island.
"Do you think I don't exist?! Shut up!"
Caesar appeared in front of Acnologia like lightning.
His eyes flashed with determination.
He swung his right arm and punched upward with all his strength.
A fierce uppercut hit Acnologia's chin like a cannonball.
The punch was like a thunderbolt, with unparalleled speed and power.
Acnologia was preparing to spit fire, but Caesar's fist hit his chin, causing the dragon breath to explode in his mouth.
With a loud bang, thick black smoke blew from Acnologia's mouth.
His body retreated due to the huge impact.
His eyes revealed astonishment and pain.
He did not expect Caesar to have such strong attack power.
Acnologia did not give up.
After stabilizing, he launched a counterattack.
He opened his claws and pounced toward Caesar with amazing speed and strength.
"Look directly at me, bastard!"
Caesar's whole body burned with the flames of the sun.
He threw a heavy punch, colliding with Acnologia's claw.
"Roar!"
Acnologia howled miserably.
Dragon scales splattered everywhere.
He actually lost to Caesar in this punch!
"Acupuncture points."
The two fists collided, and Acnologia felt the air around him sticky, like falling into honey.
He was completely unable to move.
"Seeking Dao Jade."
Several black balls behind Caesar rushed toward Acnologia.
Magic exploded all over the dragon's body.
He broke free from the acupoints, opened his mouth, and swallowed the Truth-Seeking Jade.
"Burst!"
Seeing this, Caesar was ready to teach him a lesson.
The energy in the Dao-Seeking Jade exploded inside Acnologia.
The force caused Acnologia to spurt blood, but he used his dragon stomach to digest it.
"The roar of the black dragon!"
"The roar of the God-Slaying Dragon!"
The two roars collided.
The black dragon, absorbing a large amount of magic power, caught up with Caesar.
Caesar smacked his lips in dissatisfaction.
He lost because his mouth was too small.
"But if you want to eat, I'll let you eat as much as you want!"
Caesar clasped his hands and blasted a huge Kamehameha at Acnologia.
This time, Acnologia did not take it lightly and dodged.
Caesar waved his hands.
The Kamehameha turned and hit Acnologia's back hard.
"Boom!"
With a loud bang, the black dragon smashed into the sea like a meteorite, causing huge waves.
The shockwave spread in all directions.
Wherever it passed, seawater tore apart, forming a bottomless ravine.
A huge explosion occurred.
The energy was terrifying, as if it could destroy the world.
The sea rolled violently, forming a vortex.
The temperature in the center was so high that surrounding water evaporated.
In the blink of an eye, a massive mushroom cloud rose.
It blocked the sunlight, darkening the sky.
The waves surged toward Tenrou Island like a mountain torrent.
The waves seemed to swallow the island.
The next moment, Erza and Mirajane pierced them, preventing much damage.
"Go to hell!"
Caesar increased his output.
The Kamehameha, originally a hundred meters long, increased five times and continued bombing Acnologia on the seabed.
"Crack!"
Seabed plates broke violently, making blood-curdling noises.
Each plate triggered shockwaves, making the surrounding water surge wildly.
Huge whirlpools and waves formed.
Everyone trembled in fear.
They stared at Caesar and Erza, who were fighting fiercely, eyes wide.
The power of these two far exceeded imagination.
People wondered if this battle could destroy the planet beneath them.
"Roar!"
Although Acnologia was hit, he absorbed magic power.
While enduring Caesar's attack, he swallowed the magic in big gulps.
After accumulating enough, Acnologia roared and blocked the Kamehameha.
He used this opportunity to escape and transformed into human form, soaring into the sky.
"You bastard, I will destroy you!"
Acnologia's eyes were full of a crazy desire for destruction.
"Finally, his true form is revealed."
Caesar raised his hand, and the last nail popped out.
His skin darkened.
He put on the Wolf King's Fang boxing gloves.
"I heard you're immune to magical damage.
I wonder if your body can withstand a few punches."
Caesar increased his magic output.
Faint black lines appeared on his body surface.
