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

In the fierce battle, they found that the beast's weakness was a red gem on its forehead. As long as the gem was destroyed, the beast could be defeated.

Luffy and the others began to focus on attacking the red gem on the beast's forehead. Luffy used his rubber arm to launch himself onto the beast's forehead, and then punched the gem with all his strength: "Rubber? Great Ape King Spear? Treasure Crusher!" This punch hit the gem with great force. The beast let out a huge scream and then fell down.

They continued to explore the forest and found an ancient ruin. The gate of the ruin was closed and there were various traps around it. Usopp carefully observed the traps and began to crack the traps with his rich experience.

With Usopp's efforts, they successfully avoided the trap and entered the ruins. There were many ancient artifacts and mysterious instruments in the ruins. Deep in the ruins, they saw a huge stone platform, on which was placed a box emitting golden light.

"What's in this box?" Luffy reached out curiously to take it. The moment he touched the box, a group of phantom warriors suddenly appeared around him. These warriors were illusory, holding various weapons, and attacked Luffy and others.

Luffy uses his rubber arms to fight the phantom warrior: "Rubber? Whip!" Zoro, Sanji and others also take action. Zoro's sword flashes through the phantom: "Three Swords Style? Tiger Hunting!" Sanji's fire kicks across the phantom warrior: "Devil Wind Kick? The finishing touch!"

Nami uses the weather stick to summon wind and rain to disrupt the movement of the Phantom Warriors. Usopp takes out a special "Phantom Disperser" and fires it at the Phantom Warriors. The bomb explodes and emits a special energy that temporarily disperses some of the Phantom Warriors. Chopper transforms into a combat form and attacks the Phantom Warriors with his antlers and fists. Robin uses the power of the Hana-Hana-no-fruit to set up obstacles around the Phantom Warriors to restrict their movement. Franky attacks the Phantom Warriors with laser beams, while Brook uses the Soul Sound to disrupt the Phantom Warriors' attack rhythm.

During the battle, they discovered that the phantom warrior's weakness was a blue crystal in its chest. As long as the crystal was destroyed, the phantom warrior would disappear.

Luffy and the others began to focus on attacking the blue crystal on the Phantom Warrior's chest. Luffy used his rubber arm to launch himself to the side of the Phantom Warrior, and then punched the crystal with all his strength: "Rubber? Great Ape King Spear? Crystal Breaker!" This punch hit the crystal hard with great force. The crystal on the Phantom Warrior's chest shattered and they all dissipated in the air.

They successfully opened the golden box and found an ancient secret book inside. This secret book recorded a powerful method of training. Luffy and others decided to take the secret book away and study and practice it in their free time during the voyage.

After leaving the ruins, they continued to explore the island. On the other side of the island, they found a huge lake. The water of the lake was a strange color, and there was a small island in the center of the lake. On the small island, there was a shining lighthouse.

"That lighthouse looks mysterious, let's go take a look." Luffy said. They took a boat to the island in the center of the lake and boarded the lighthouse. There was a huge energy device inside the lighthouse, which was constantly releasing energy fluctuations.

"What is this device for?" Franky studied it curiously. At this moment, a group of mechanical creatures rushed in. These creatures looked like robots, their bodies were made of metal, and their eyes were flashing red light.

"Outsiders, you dare to break into our energy base, you will be destroyed!" The leader of the mechanical creatures said in a cold voice. Luffy responded fearlessly: "We are just here to take a look, we have no ill intentions!"

But the mechanical creatures ignored him and launched attacks one after another. Luffy used his rubber arms to fight the mechanical creatures: "Rubber? Machine gun!" Zoro, Sanji and others also quickly launched a counterattack.

Zoro's sword flashed across the mechanical creature: "Three Swords Style? Raikiri!" Sanji's fire kick melted part of the mechanical creature's metal shell: "Devil Wind Kick? Electric Oven!"

Nami summoned lightning with the weather stick and struck the mechanical creatures. Usopp took out a special "Mechanic Buster Bomb" and fired it at the mechanical creatures. The bomb exploded on the mechanical creatures, creating some gaps. Chopper transformed into a giant form and hit the mechanical creatures with his body. Robin used the power of the Hana-Hana Fruit to set up obstacles around the mechanical creatures to restrict their movements. Franky used laser beams to attack the vital parts of the mechanical creatures, and Brook used the Voice of the Soul to interfere with the movements of the mechanical creatures.

During the battle, they discovered that the mechanical creatures' weakness was an energy core in their heads. As long as this core was destroyed, the mechanical creatures would stop functioning.

Luffy and the others began to focus on attacking the energy core in the head of the machine creature. Luffy used his rubber arm to launch himself into the head of the machine creature, and then punched the core with all his strength: "Rubber? Great Ape King Spear? Breaking the Core!" This punch hit the core with great force. The core of the machine creature's head was shattered, and they were paralyzed on the ground.

They successfully controlled the lighthouse's energy device, converted its energy into a special energy source, and stored it for future use.

After leaving the lighthouse, they rested on the island for a while and then sailed away from the mysterious island.

During the voyage, they encountered an island floating in the air, which was supported by a mysterious force and surrounded by a gorgeous rainbow.

"Wow, Sky Island! Let's go up and take a look!" Luffy shouted excitedly. They tried every possible way, using balloons and wind power, and finally succeeded in landing on Sky Island.

The environment on the Sky Island is very unique, with gravity much lower than on the ground, so people can easily jump very high. The architectural style here is also unique, with houses that look like they are made of clouds.

In the center of Sky Island, there is a huge temple. The door of the temple is closed, and it is surrounded by various mysterious runes and magic circles. Luffy and others tried to approach the temple, but were blocked by the energy released by the magic circle.

"This magic circle is so powerful, we have to find a way to break it." Robin said. Usopp began to study the rules of the magic circle, and after some effort, he found the flaw in the magic circle.

Following Usopp's instructions, they successfully passed through the magic circle and entered the temple. The interior of the temple was very magnificent, with various gems inlaid on the walls, which emitted a dazzling light.

Deep inside the temple, they saw a huge angel statue, holding a huge lightsaber in its hand, with a mysterious light flashing on the sword.

"This lightsaber looks powerful. Should we take it away?" Luffy asked curiously. Robin thought for a moment and said, "This lightsaber may be a sacred object of Sky Island. We can't take it away easily. Let's leave it here."

Just as they were about to leave the temple, a group of angel warriors suddenly appeared. These warriors were dressed in white robes, had wings on their backs, held weapons in their hands, and had majestic eyes.

"You mortals, you dare to trespass into the temple, you will be punished by God!" said the leader of the angel warriors. Luffy responded: "We have no ill intentions, we just come to visit."

But the angels didn't believe it and launched an attack. Luffy used his rubber arms to fight the angels: "Rubber? Whip!" Zoro, Sanji and others also used their special skills.

Zoro's sword flashed among the angel warriors: "Three sword styles? Demon slash!" Sanji's flaming kick streaked across the angel warriors: "Devil Wind Kick? The finishing touch!"

Nami uses the weather stick to summon wind and rain to disrupt the angels' actions. Usopp takes out a special "Angel Buster Bomb" and fires it at the angels. The bomb explodes and emits a special energy that temporarily weakens the angels' power. Chopper transforms into a combat form and attacks the angels with his antlers and fists. Robin uses the power of the Hana-Hana Fruit to set up obstacles around the angels to restrict their actions. Franky attacks the angels with laser beams, while Brook uses the Soul Sound to disrupt the angels' attack rhythm.

During the battle, they discovered that the angel warriors' weakness was a golden feather on their wings. As long as this feather was destroyed, the angel warriors would lose their fighting power.

Luffy and the others began to focus on attacking the golden feathers on the wings of the angel warriors. Luffy used his rubber arm to catapult himself to the side of the angel warriors, and then punched the feathers with all his strength: "Rubber? Great Ape King Spear? Pull out the feathers!" This punch hit the feathers hard with great force. The feathers on the wings of the angel warriors were pulled out, and they fell to the ground one after another, losing their fighting power.

They successfully left the temple and continued to explore the Sky Island. On the edge of the Sky Island, they found a magical fruit that grew in the clouds and exuded an alluring aroma.

"What kind of fruit is this? It looks delicious!" Luffy couldn't help but pick one and took a bite. Instantly, he felt his body full of strength, and his speed and reaction ability were greatly improved.

"Wow, this fruit is amazing!" Luffy said excitedly. They collected some of this fruit and prepared to take it back for research.
