One Piece: The Straw Hat Pirates' Max-Level Swordsman

Luffy nimbly dodged the sharp arrows with his rubber body. He laughed and responded, "Humph, is that all you can do?" Zoro quickly slashed out a few sword energies, smashing the sharp arrows shot at him, his eyes becoming more determined, "Don't underestimate us!"

Sanji found the right moment, ignited flames on his legs, and performed the Devil's Wind Kick: "Devil's Wind Kick? Devil's Dance!" Countless flaming kicks rained down on the dark magician. The dark magician was forced to take a few steps back by the sudden attack, and the flames burned several holes in his black robe.

Nami used the weather stick to summon a gust of wind, disrupting the attack direction of the dark arrows and dissipating the surrounding darkness. Usopp took out the newly invented "Flash Shock Bomb" and threw it at the dark magician. The bomb exploded with a strong light and impact, causing the dark magician to lose his sight and balance for a short time.

Chopper transformed into a giant reindeer, and while the Dark Mage was in a panic, he used his huge antlers to attack him: "Antler Enhancement? Charge!" This attack directly knocked the Dark Mage into the wall of the tower. Robin used the power of the Hana-Hana Fruit to grow countless arms on the wall, trying to grab the Dark Mage and restrict his movements.

Franky turned on the laser beam mode and fired several powerful lasers at the dark magician: "Laser beam? Heavy rain!" Brook used the sound of the soul to interfere with the dark magician's mind. His music echoed in the tower, causing some chaos in the dark magician's magic.

The dark magician was furious, his body began to swell, and the dark aura swirled around him like a substance. "You ants, how dare you hurt me? I will make you pay the price!" He waved his hands, and the dark aura condensed into a huge dark monster. The monster was huge, with sharp claws and a bloody mouth, exuding a terrifying aura.

Luffy looked at the monster and rushed forward without fear: "Rubber? Ape King Gun Random Hit!" His fists rained down on the monster, each punch carrying great power. Zoro also rushed forward and coordinated with Luffy: "Three Swords Style? Secret? One Big? Three Thousand? The Great Thousand Worlds!" His sword light left deep wounds on the monster.

Sanji, Nami and others were not idle either. They attacked the monster from all directions, trying to distract it. However, the monster's recovery ability was very strong, and its wounds healed quickly under the repair of the dark aura.

"This guy is not easy to deal with. We have to find its weakness!" Ling Tian shouted. In the fierce battle, they found that the monster was very afraid of the power of the Light Stone. Whenever it approached the light emitted by the Light Stone, the monster's movements would become slow.

So, Luffy and his team changed their tactics. They asked Robin to use the power of the Flower-Flower Fruit to send the Light Stone to the vicinity of the monster, and use the power of the Light Stone to restrict the monster's actions. At the same time, Luffy and his team launched a more violent attack.

Luffy stretched his rubber arm to the limit, and then ejected it like a spring: "Rubber? Lion Bazooka!" His attack accurately hit the monster's head, causing the monster to roar in pain. Zoro saw the opportunity, jumped on the monster's back, and inserted three swords into the monster's body: "Three Swords Style? Ghost Energy? Nine Swords Style? Ashura? Ichimiri Silver!" The powerful sword energy burst out from the monster's body, causing the monster's body to begin to shake.

Sanji used his strongest Devil's Wind Kick move: "Devil's Wind Kick? The highest level of minced meat!" His attack was like a cannonball, exploding in the belly of the monster. The other companions also used their strongest skills to launch the final attack on the monster.

With everyone's concerted efforts, the monster was finally completely destroyed and turned into a dark aura that dissipated in the air. The dark magician was horrified when he saw his monster was defeated, but he still said stubbornly: "Humph, even without the monster, I can still deal with you!"

He cast a powerful dark magic circle, and countless dark ghosts emerged from the magic circle. These ghosts rushed towards Luffy and others with their fangs and claws. They could pass through the entity and directly attack the soul of a person.

Brook felt the threat of the ghost, and he stepped forward: "Soul out of the body? The chill of the underworld!" He used his soul power to fight against the ghost, trying to buy time for his companions. Luffy and others also felt the oppression of the soul, but they did not retreat.

Luffy used his rubber ability to spin his body: "Rubber? Tornado!" His rotation created a strong airflow, blowing away the approaching ghosts. Zoro, Sanji and others used their own armed color domineering to wrap their weapons and bodies to resist the ghost's soul attack.

Nami summoned lightning with the weather stick, and Usopp fired ammunition with special runes, which had a certain effect on ghosts. Chopper ate the blue ball and went into a rampage state, attacking ghosts with great force. Robin used the power of the Hana-Hana Fruit to control the surrounding objects and block the ghosts' progress. Franky used his laser beam and flamethrower to attack ghosts in a large area.

During the battle, they found that the ghost would briefly materialize when passing near the Light Stone, so they used the Light Stone again to lure the ghost around the Light Stone and then launched an attack.

After a hard fight, they finally eliminated all the ghosts. The dark magician's face turned very pale, and his magic power had been consumed by half, but he was still unwilling to fail. He took out his last trump card - the Dark Holy Grail.

The Dark Holy Grail is a cursed artifact that can absorb the dark power around it and amplify it several times. The dark magician poured all his remaining magic power into the Dark Holy Grail, which emitted a dazzling black light, and the entire tower was shaking.

"You will all be swallowed by darkness!" The dark magician laughed wildly, and the Holy Grail released a powerful dark shock wave, sweeping towards Luffy and the others. Wherever this shock wave went, everything was corroded by darkness, and cracks began to appear on the walls of the tower, as if the entire sky city was about to be destroyed.

Luffy and the others felt an unprecedented crisis, they looked at each other with determination in their eyes. They held hands and gathered their strength together to form a huge energy shield.

"We will not be defeated by you!" Luffy shouted. The shield was shaking under the impact of the dark shock wave, but their faith prevented the shield from being broken. While resisting the shock wave, they were also thinking about countermeasures.

Robin suddenly remembered that the Dark Grail's weakness was mentioned in the classics. Although the Dark Grail was powerful, it could not withstand the simultaneous attack of pure positive energy and the opposing elemental power.
