Chapter 525: The Redemption of Mechanical Island and the Exploration of Blue Island after Escaping f

Zoro's sword flashed across the Fire Giant: "Three Swords Style? Tiger Hunting!" Sanji's fire kick blended with the Fire Giant's flames: "Devil's Wind Kick? Hell Flame!" Nami used the Weather Stick to summon rain, trying to extinguish the Fire Giant, but the rain evaporated instantly as soon as it touched the Fire Giant.

Usopp took out a special "Flame Giant Buster Bullet" and fired it at the Flame Giant. The bomb exploded on the Flame Giant, temporarily weakening its flame power. Chopper transformed into a giant form and hit the Flame Giant with his body. Robin used the power of the Hana-Hana Fruit to set up obstacles around the Flame Giant to restrict its movement. Franky used laser beams to attack the vital parts of the Flame Giant, and Brook used the Soul Sound to interfere with the Flame Giant's movement.

In the fierce battle, they found that the weakness of the fire giant was the blue flame heart in its chest. As long as the flame heart was destroyed, the fire giant could be defeated.

Luffy and the others began to focus on attacking the Flame Heart in the Fire Giant's chest. Luffy used his rubber arm to launch himself into the Fire Giant's chest, and then punched the Fire Heart with all his strength: "Rubber? Great Ape King Spear? Extinguish fire!" This punch hit the Fire Heart with great force. The Fire Heart was instantly extinguished, and the Fire Giant let out a huge scream, then turned into a ball of ash and dissipated in the air.

They successfully defeated the fire giant and walked into the volcanic palace. A strong energy wave filled the palace, and deep in the palace, they saw a huge fire gem. This gem exuded a dazzling light and contained a powerful fire power.

"This gem looks very powerful. Should we take it away?" Luffy asked curiously. Robin thought for a moment and said, "The power of this gem is too strong. If it falls into the wrong hands, it may cause a huge disaster. We'd better seal it up or find a suitable place to store it."

Just as they were discussing how to deal with the Flame Gem, they suddenly heard a huge roar coming from outside. They walked out of the palace and saw that the volcano began to erupt violently, and the magma rushed towards them like a torrent.

"Oh no, the volcano is erupting, we have to get out of here!" Franky shouted. They quickly ran towards the sea, but the lava was so fast that it was about to catch up with them.

At the critical moment, Chopper discovered a secret passage leading to the sea. They ran desperately along the passage and finally boarded the ship before the magma flooded the island and escaped from the island surrounded by flames.

Luffy and his companions continue to sail on the sea. They don't know what kind of challenges they will encounter in the next adventure, but they are not afraid, because they are the Straw Hat Pirates, a group of adventurers who always pursue their dreams and move forward courageously. They believe that as long as everyone unites, nothing can stop them from continuing to write their own legendary stories on the Grand Line.

After a while, they came to a mechanical island, which was full of huge mechanical devices and towering chimneys, and the roar of machines was endless.

"This place looks so cool, it's all machines!" Luffy said excitedly. They boarded the island and found that the residents were all robots. These robots had complex body structures and were flexible in their movements. Some were busy working, and some were patrolling.

In the center of the island, there is a huge mechanical castle. The castle's gate is closed and surrounded by various defense devices. Luffy and others tried to approach the castle, but were blocked by the lasers emitted by the defense devices.

"These defense devices are so powerful, we have to find a way to break through them." Zoro frowned and said. Usopp carefully observed the defense devices and discovered their attack patterns. He took out some special tools and began to interfere with the defense devices.

Thanks to Usopp's efforts, the attack of the defense device was briefly paused. Luffy and others took the opportunity to rush to the castle gate. Luffy used his rubber arms to pull the gate hard, and Zoro, Sanji and others also helped. After some efforts, the gate finally slowly opened.

They walked into the castle, which was a huge mechanical world. Various sophisticated mechanical instruments were running, and mechanical drawings and design plans were hung on the walls. Deep in the castle, they saw a huge mechanical core. This core exuded powerful energy and was the power source of the entire mechanical island.

"This is the core of the mechanical island, so spectacular!" Franky exclaimed. However, they found that the mechanical core seemed to be infected by a virus, causing the operation of the mechanical island to become disordered. If the virus is not removed in time, the mechanical island may collapse.

Robin found some information about the mechanical core and the virus in the castle, and she began to study it. After some effort, she found a way to remove the virus, but it required a special program code.

Usopp, with his inventive talent, began to write this special program code. In the process of writing the code, they were attacked by the defense robots on the mechanical island. These robots were well-equipped and moved quickly, causing them a lot of trouble.

Luffy used his rubber arms to attack the robot: "Rubber? Machine gun!" His attacks rained down on the robot, but the robot's shell was so hard that Luffy's attacks could only leave some shallow marks on it. Zoro, Sanji and others also used their special skills to fight the robot.

Zoro's sword flashed on the robot: "Three Swords Style? Demon Slash!" Sanji's fire kick melted part of the robot's shell: "Devil Wind Kick? The finishing touch!" Nami summoned lightning with the weather stick and struck the robot. While writing code, Usopp took out some simple weapons and fired at the robots, temporarily blocking their attacks.

Chopper transformed into a combat form and attacked the robots with his antlers and fists. Robin used the power of the Hana-Hana-no-fruit to set up obstacles around the robots to restrict their movements. Franky used laser beams to attack the robots' vital parts, while Brook used the Soul Voice to interfere with the robots' movements.

In the fierce battle, Usopp finally completed the program code. They input the code into the mechanical core and successfully removed the virus. The operation of the mechanical island returned to normal, and the robots were grateful to Luffy and others.

Luffy and his friends enjoyed a happy time on the Mechanical Island, learned a lot of new mechanical knowledge, and after upgrading and renovating the Thousand Sunny, they set sail again and headed for unknown waters.

A few days later, they found an island emitting a faint blue light. The sea water around the island was a deep blue, like a huge blue gem.

"Wow, that island looks awesome, there must be something interesting waiting for us!" Luffy danced with excitement. As the ship approached the island, they saw many huge crystal pillars on the island. These crystal pillars towered into the sky, and strange electricity flashed inside.
