A magic merchant infiltrating Fairy Tail

Generally speaking, having aerial combat capabilities gives you a significant advantage in battle, but Erza has armor that allows her to fly, so this advantage is essentially wasted.

On the arena, Jhin circled several times, spread his wings, and wrapped them with domineering aura, instantly transforming them into two large, black shields that were both offensive and defensive. Then, he suddenly swooped down and attacked Erza at an extremely fast speed!

"Emperor Dan Gong!!"

When there is no fire, the Lunaria's defense will decrease, but their speed will increase significantly.

Everyone saw a black line slicing through the air at incredible speed, instantly breaking through a distance of tens of meters, and arriving on the arena from high above, right in front of Erza.

Jhin moved quickly, but Erza changed clothes even faster!

"Diamond Shield!!"

A silver-white shield, crafted from a mixture of high-density metal and ore, was summoned by Erza to shield her. It was the most robust defensive shield among all her equipment and could be used independently of the Vajra Armor.

The Shield of Diamond has extremely high defensive capabilities. Every time it is used, it can block fatal attacks for Erza. Even the powerful cluster cannon of the magicians cannot break through its defense, let alone the attack of King.

So how powerful is the Magic Cluster Cannon? It can easily destroy half a town!

Kid's strongest attack after awakening his Magnet-Magnet Fruit, the 'Electromagnetic Cannon,' is about this power, and his electromagnetic cannon can even damage Big Mom's steel body.

A simple substitution would be: the Vajra Shield is equivalent to an old lady.

Although King's Dan Bow Emperor is very destructive, it is ultimately a physical attack created by pure physical strength, Armament Haki, and high-speed movement, and it is definitely not able to break through Big Mom's defense.

clang!!

The Pteranodon's wings collided with the Adamantine Shield, causing the air to vibrate at high frequencies. A massive energy shockwave formed an airflow that swept around the area starting from the point of impact.

"So hard..."

Its attack could easily destroy a small mountain, yet when it struck the shield, the shield didn't budge an inch, not even leaving a single white mark?!

Impossible! Absolutely impossible!

Slightly unconvinced, Jin decided to try again, so he leaped up and then swooped down.

With another clang, the Pteranodon retreated several meters, flapped its wings, and found that the shield in front of it was still standing there, without moving an inch. Now it saw the truth.

"What material is this shield made of? It feels even stronger than Seastone..."

Before he could figure it out, Erza had already launched her attack: "Heavenly Wheel - Blazing Sword!"

Hundreds of silver iron swords were summoned again, this time at an even faster pace.

But by this time, Jhin's cooldown had ended, and bright flames ignited on his body once again, his defenses were back to full.

This time, he didn't stand still to defend. Instead, he used his flight ability to dodge the attacks of the Heavenly Wheel Sword in the air, trying to prolong the duration of the flames.

Thus, the scene above the arena became this: a huge black pteranodon, its body wreathed in flames, soared through the air, while white swords attacked it from all sides.

Under Erza's control, the speed of the Heavenly Wheel Swords was also increased. They were like remote-controlled missiles, relentlessly pursuing the burning Pteranodon, forcing it to flee in a sorry state.

But this situation didn't last long. After all, Jhin wasn't the type to just run away, nor was he the type to just hide when faced with a barrage of attacks.

He had full confidence in both the racial characteristics of the Lunaria race and his own strength!

"You want to hit me? Then hit me as hard as you want! Even Kaido, without using his Overpowering Technique, might not be able to break through my full defense. You think a single volley of swords will break through? Wishful thinking!"

Jin soared into the sky with a backflip, then suddenly stopped. Looking down at the flying swords that were chasing him, he flapped his wings, and countless fire bullets were fired from the flames behind him, like machine guns, making a continuous 'rat-a-tat-tat' sound.

"The Twin Emperors of Blades!!"

With their superior position, they swept through the enemy lines with unstoppable momentum!

The fire bullets were incredibly powerful, forming two torrents with the Heavenly Wheel Sword, one above and one below. They clashed in mid-air, making a constant clanging sound, but in the end, the bullets and the sword perished together, and the two sides were evenly matched once again.

Just then, Jhin made a surprising move!

He pulled his head back forcefully, distorting his face.

"What is this...?!"

"Hahaha...his expression is so funny!!"

The clueless pirates began to laugh at King's face, wishing they could turn his current appearance into memes and publish them in the newspapers for widespread publicity.

Erza, however, did not mock him, because she knew this was Jhin's attack method.

Pulling on the head forcefully and then releasing it like this will launch a huge shockwave, like a slingshot, with a speed like a laser, making it almost impossible to avoid.

The next moment, Jin released his grip, and a black shockwave burst out from the bone crown on its head!

"Diao is the emperor of self-esteem!!"

Whoosh—Bang!

With a deafening roar, half of the arena was instantly shattered by this attack, sending up thick dust more than ten meters high!

Those pirates who had been mocking King suddenly froze on their faces, unable to laugh anymore. They just stood there with their mouths open, sweating profusely, speechless.

Before long, the smoke and dust dissipated, and Jin looked around, only to find that there was no trace of Erza on the ground.

"Huh?! Where did they go?!"

"Up there!!" A loud shout came from above.

Jin's pupils contracted, and he looked up at the sound. Before he could even see the other person clearly, he was struck by two heavy slashes on his face!

boom!!

With a loud bang, the more than six-meter-long Pteranodon was slammed heavily to the ground!

Only then did everyone realize that Erza had taken advantage of the dust and smoke to quietly move above Jin and even changed her weapon.

"That is……"

Kira explained to everyone, "Those are red and black twin blades, imbued with Dragon Slayer magic!"

Just like Erza's collection of armor and weapons specifically designed to counter certain attributes, this set of red and black twin blades has become her weapon for fighting dragons.

The Dragon Slayer Seal is imbued with various attributes such as fire, lightning, wind, iron, light, darkness, poison, and moon. It can be activated at any time, and then the desired Dragon Slayer attribute can be switched for battle.

"The opponent has special defensive capabilities, and dragons also have a certain resistance to magic. Erza probably wanted to see if a dragon-slaying weapon would be effective against him, but it seems unlikely!"

Killer was also quite curious, but he was curious whether it would work on Kaido, since Kaido is the dragon.

Erza pressed her advantage, wielding two swords, and swooped down like a falling meteor, striking at Jin.

However, the strike missed its mark!

With a single step, Jin traversed several meters, simultaneously entering his strongest human-beast form. He returned to the spot where his weapon had fallen, picked up the longsword that had slipped from his grasp, and then soared into the sky. Raising the longsword in his right hand, a large amount of flames enveloped his arm, spiraling and gradually transforming into the shape of an Eastern dragon.

"Guardian Fire Dragon Emperor!!"

The fire dragon opened its huge mouth and roared, aiming directly at Erza on the ground. The extreme heat created a hot wind throughout the arena, making the audience sweat profusely and their lips dry!

"It's so hot!!"

"It's just like lava..."

As is well known, there is a setting in the world of One Piece where magma is hotter than flames.

But Natsu's flames can even burn magma. To the Fairy Tail mages, who are already familiar with such high-temperature flames, the fire dragon in front of them is nothing more than a clown.

"In the end, it's just a flame design; it doesn't have a trace of dragon power!" Erza said coldly. Her Heavenly Wheel Armor unfolded, and she flew up like a fairy, then switched weapons in mid-air.

"The Sword of the Wind God!"

Logically, wind should fan the flames, but the attack of the Wind God's Sword is different. After it is swung, it can create a violent wind that can disperse everything it cuts, including the flames.

boom!!

As the storm passed, the fire dragon, which was originally in an energy state, was torn to shreds in an instant.

"What?!"

Jin was horrified, seemingly not expecting that his long-awaited ultimate move would be so easily broken. But what shocked him even more was that his flames disappeared at that moment, and Erza's attack was already right in front of him!

"How could it be such a coincidence?! Could it be... that she had planned the timing all along?"

In mid-air, Erza's armor and weapon changed again, replacing the Heavenly Wheel Armor and the Wind God's Sword with the set of equipment with the strongest offensive power—

A garment of tranquility!

The Demon Blade Crimson Tassel!!

The lightest equipment ensures ultimate speed.

At this moment, the two were less than three meters apart, and it would only take one second for them to strike each other.

His body seemed to be locked in place, unable to dodge, he could only block!

But at that moment, a resolute glint appeared in Jhin's eyes: "I cannot lose this battle!"

Even without the flames, he still had Armament Haki and the super-strong defensive power granted by his Zoan-type Devil Fruit! Judging from the force of the opponent's attack just now, even if it had actually hit him, he would still have a fighting chance!

Thinking of this, he quickly controlled his body's energy, gathering Armament Haki in front of him, right where the twin swords were about to strike.

The intense Armament Haki turned the area pitch black!

Stab it--!

A flash of black lightning in his sight interrupted all of Jin's thoughts.

His pupils contracted instantly, his eyes widened in astonishment as he stared at Erza, who was raising her sword to strike him: "How is this possible?! You have one too..."

Crimson hair danced in the air, and a demonic sword, dyed a deep black by a great deal of domineering aura, conjured several crackling black lightning bolts out of thin air. These were the postures of the kings of the sea, using their domineering aura to the extreme!

Conqueror's Haki envelops you!

The interplay of black and red makes Erza look like an elegant and alluring fairy.

In a flash, King noticed Erza glancing at the spot where he was using Armament Haki for defense, her eyes remaining calm, as if she had expected it.

He was even more shocked: 'Not only did she calculate the time when the flames would disappear, but she also foresaw that I would use Haki for defense?! Could it be Observation Haki's precognitive ability...?'

'No! It seems to be solely based on extensive combat experience and extraordinary intuition!'

The black blade of light slashed down heavily, as if it were about to cleave the heavens and the earth. That was Erza's strongest move, the Slash of Determination!

Puff-!

Blood splattered everywhere!

Jin's eyes rolled back, his mouth coughed up blood, and he plummeted through the air.

'Do you also want to become king...?'
