Chapter 517: Adventure in the Cold Sea: Exploring the Ice Castle and Resolving the Ice and Snow Cris

With the joint efforts of everyone, they finally succeeded in changing the direction of the iceberg and avoided the danger of the ship being hit. However, just when they breathed a sigh of relief, a group of huge ice monsters emerged from the iceberg. These ice monsters were made of ice blocks, and their eyes were shining with blue light. They attacked Luffy and others.

Luffy used his rubber arm to attack the ice monster: "Rubber? Bazooka!" His attack caused some cracks to appear on the ice monster's body. Zoro, Sanji and others also fought with the ice monster on the ice.

Zoro's sword flashed on the ice monster: "Three Swords Style? Tiger Hunt!" Sanji's fire kick melted part of the ice monster's body: "Devil Wind Kick? Lamb SHOT!" Nami summoned a cold wind with the weather stick, freezing the ice monster's movements. Usopp took out the newly invented "Ice Monster Disintegration Bomb" and fired it at the ice monster. After the bomb exploded, the ice monster's body disintegrated.

Chopper transformed into a combat form and attacked the ice monster with his antlers. Robin used the power of the Hana-Hana Fruit to set up obstacles around the ice monster to restrict its movements. Franky used laser beams to attack the ice monster's vital parts, and Brook used the sound of the soul to interfere with the ice monster's thinking.

In the fierce battle, they found that the weakness of the ice monster was a blue ice crystal on its chest. As long as the ice crystal was destroyed, the ice monster could be defeated.

Luffy and the others began to focus on attacking the ice crystal on the ice monster's chest. Luffy used his rubber arm to launch himself into the ice monster's chest, and then punched the ice crystal with all his strength: "Rubber? Great Ape King Spear? Break the Ice!" This punch hit the ice crystal hard, and the ice crystal shattered instantly. The ice monster let out a painful roar, and then turned into a pile of ice cubes and dissipated on the ice surface.

They successfully repelled the ice monster and continued to sail in the cold sea. During the voyage, they found an island covered with ice and snow. On the island there was a huge castle, and the walls of the castle were covered with ice ridges, which looked very spectacular.

"Let's go to that castle and see, maybe there's something interesting inside." Luffy said excitedly. They boarded the island and walked towards the castle. When they walked into the castle, they found that it was filled with a cold atmosphere, and there were some huge ice sculptures hanging on the walls.

In the castle hall, they saw a huge ice throne. On the throne sat a man in a white robe, with a stern face and a majestic look in his eyes.

"Who are you? Why did you come to my ice castle?" the man in white asked. Luffy replied, "We are the Straw Hat Pirates. We saw this castle while sailing on the sea and wanted to come and see it."

The man in white frowned slightly: "This castle is my territory, outsiders are not welcome. You'd better leave immediately." Luffy was not scared by his words, he said: "We just want to rest here and avoid the cold outside."

The man in white was silent for a while, then said: "Okay, you can rest here, but don't touch anything in the castle at will."

After Luffy and the others thanked the man in white, they rested in the castle. However, during the rest, they found some secrets hidden in the castle. Chopper found an ancient book in a corner of the castle, which recorded a power that could control ice and snow.

Robin picked up the book and read it carefully. Her face became very solemn: "If this power is abused, it will bring great disaster to this cold sea. We must prevent this power from falling into the hands of bad people."

Just as they were discussing how to deal with the book, a man in white suddenly appeared in front of them. His eyes revealed a greedy look: "You found this book, which is the source of my power. Give it to me!"

Luffy and his friends realized that the man in white wanted to use this power to do bad things, so they firmly rejected his request. When the man in white saw that Luffy and his friends were unwilling to hand over the books, he showed his ferocious face, cast magic, and summoned a group of ice warriors.

These Ice Warriors, whose bodies are made of ice, hold ice swords and rush towards Luffy and his companions. Luffy attacks the Ice Warriors with his rubber arms: "Rubber? Machine gun? Shoot!" His attacks rain down on the Ice Warriors, but the Ice Warriors' bodies are so hard that Luffy's attacks do not cause much damage to them.

Zoro, Sanji and others also used their special skills to fight the Ice Warrior. Zoro's sword flashed among the Ice Warriors: "Three Swords Style? Devil Slash!" Sanji's fire kick melted part of the Ice Warrior's body: "Devil Wind Kick? The finishing touch!"

Nami summoned lightning with the weather stick and struck the Ice Warrior. Usopp took out the newly invented "Ice Warrior Disintegration Bomb" and fired it at the Ice Warrior. The bomb exploded and disintegrated the Ice Warrior's body. Chopper transformed into a giant form and hit the Ice Warrior with his body. Robin used the power of the Hana-Hana Fruit to set up obstacles around the Ice Warrior to restrict their movements. Franky used laser beams to attack the Ice Warrior's vital parts, and Brook used the Soul Sound to interfere with the Ice Warrior's thinking.

In the fierce battle, they found that the weakness of the Ice Warrior was a blue gem in their chest. As long as the gem was destroyed, the Ice Warrior could be defeated.

Luffy and the others began to focus their attacks on the gem on the Ice Warrior's chest. Luffy used his rubber arm to launch himself into the Ice Warrior's chest, and then punched the gem with all his strength: "Rubber? Great Ape King Spear? Treasure Breaker!" The punch hit the gem hard, and the gem shattered instantly. The Ice Warrior let out a painful roar, and then turned into a pile of ice and dissipated in the castle.

Seeing that his ice warriors were defeated, the man in white took action himself. He used powerful ice and snow magic to attack Luffy and his companions. Luffy and his companions fought hard, but the magic power of the man in white was very strong, and they gradually fell into trouble.

At the critical moment, Chopper discovered that the source of the man in white's magical power was an ice staff in his hand. As long as the ice staff was destroyed, the man in white's power could be weakened.

Luffy and the others began to focus on attacking the ice staff of the man in white. Luffy used his rubber arm to launch himself to the man in white, and then punched the ice staff with all his strength: "Rubber? Great Ape King Spear? Breaking Staff!" The punch hit the ice staff hard, and it broke instantly. The man in white roared in pain, and his magic power weakened.

Zoro, Sanji and others took the opportunity to launch a more fierce attack. With the concerted efforts of everyone, the man in white was finally defeated. They successfully prevented the man in white from using the power of ice and snow to do bad things and protected this cold sea area.

After resting for a while in the Ice Castle, Luffy and his companions continued to sail on the sea. They knew that the future adventure was still full of countless unknowns and challenges, but they were not afraid, because they were the Straw Hat Pirates, a group of adventurers who always pursued their dreams and moved forward courageously. They believed that as long as everyone was united, nothing could stop them from continuing to write their own legendary stories on the Grand Line.
