Chapter 505: Exploring the Guardian Stone in the Dreamland after Solving the Rainbow Bridge

They carefully studied the details on the map and found that these maps were partial maps of some mysterious islands, which had special geographical significance in history. By recalling the geographical knowledge they learned during the voyage and the clues they had found on the various islands before, they gradually pieced together a complete map.

Usopp used a rope to simulate the connection route of the map on the door. When the last connection was completed, the door opened. Inside was a huge sand table, which presented a miniature world with various terrains vividly. In a corner of the sand table, there was a special crystal fragment, which had clues related to other doors.

With the crystal fragments, they came to the next door. The puzzle of this door involved mysterious mathematics and geometry. The pattern on the door was a maze composed of various complex geometric figures, and there were some numbers flashing in the maze. Franky looked at the door and said excitedly: "This is a mathematical challenge. We have to find the exit of the maze and solve the puzzle according to the pattern of numbers."

Everyone began to study the route of the maze. Zoro used a knife to draw possible paths on the ground: "We have to go in from here and avoid these dead ends." Luffy stared at the numbers, trying to find their pattern: "These numbers seem to increase or decrease in a certain order."

After some effort, they found the exit of the maze and calculated a password based on the pattern of numbers. When the password was entered into the mechanism on the door, the door opened. Inside was a space full of light, with some huge geometric crystals in the space, and various mathematical formulas were engraved on the crystals. In the center of the space, there was a small console with a slot on it, which was just right for inserting the crystal fragments and crystal balls collected before.

They put the crystal fragments and crystal ball into the console, which started up and emitted a beam of light, which shone on the opposite wall and formed a new pattern. This pattern led them to the second-to-last door.

The puzzle of this door is related to music and sound. The door is engraved with patterns of various musical instruments and notes, as well as some strange sound wave patterns. Brook walked to the door and played his violin, using music to resonate with the door: "This door needs a specific musical melody to open, and we have to find this melody."

He tried various combinations of notes, while the other partners judged whether they were close to the correct answer based on the changes in the sound wave pattern on the door. After many attempts, they found a special melody. When Brook played this melody, the door slowly opened. Inside the door was a wonderful space full of music and sound, with various instruments playing automatically in the air. In the center of the space, there was a golden note-shaped object that emitted powerful energy fluctuations.

They picked up the golden note and came to the last door. This door looked very ordinary, but it exuded a majestic atmosphere. There was only a circular groove on the door, and there was no pattern around it. Luffy took the golden note and tried to put it into the groove. It fit perfectly.

As the golden musical note was put into the groove, the whole rainbow bridge shone with dazzling light, the seven doors roared at the same time, and the last door slowly opened. Behind the door was a brand new world, a world with a colorful sky, islands of various shapes floating in the sky, dense forests and rushing rivers on the ground, and some creatures that had never been seen before living freely.

Luffy shouted excitedly: "We succeeded! A new adventure begins!" The companions cheered and set foot on this unknown world. As soon as they entered this world, they felt a mysterious and powerful force calling them.

They walked towards the source of power and met some cute elves in the forest. These elves flew around them, as if welcoming them. The elves took them to a river with a bridge made of light on it.

After walking across the bridge, they saw a magnificent crystal palace. The palace exuded a mysterious light, as if hiding countless secrets. When they approached the palace, the palace gate opened automatically, and a majestic voice came from inside: "Welcome, brave adventurers, you have passed the test of the Rainbow Bridge and come here. This is the land of fantasy and dreams, with endless mysteries and treasures, but also full of dangers."

Luffy smiled and responded, "We are not afraid of danger, we are here for adventure!" They walked into the palace and found it filled with all kinds of rare treasures and mysterious devices. In the center of the palace, there was a huge crystal ball, which showed every corner of the world, and there were some flashing lights that seemed to represent important clues.

They began to explore the palace and found an ancient book in a corner. Robin opened the book and interpreted the contents: "This book records the history of the Dreamland. It was once a prosperous magical world, but it fell into a deep sleep due to a war. Now, the power here is gradually awakening, but it has also attracted the covetousness of some evil forces. We need to find five guardian stones to stabilize the power of this world and prevent it from being used by evil forces."

So, they began to look for the guardian stone according to the clues in the crystal ball and the book. In the process of searching, they encountered some creatures controlled by evil forces. These creatures were originally residents of this world, but now they have become ferocious and attacked them.

Luffy and his companions fought fiercely with these creatures. They used their respective skills and the experience accumulated in previous adventures to repel the enemy again and again. During the battle, they found that these controlled creatures were very sensitive to a special light, which was emitted by the golden notes obtained in the music space before.

They used the light of the golden notes to dispel the evil forces of some creatures and restore them to normal. These restored residents told them that the Guardian Stone was hidden in five mysterious places in the Dreamland, each of which was guarded by a powerful guardian.

Luffy and his companions first came to a valley of fire, where there were blazing flames everywhere and the temperature was extremely high. The Guardian Stone was deep in the valley, and the guardian was a huge fire phoenix. The fire phoenix was burning with flames all over its body, and as soon as it appeared, the temperature around it rose sharply.

Luffy stretched out his rubber arms and rushed towards the flaming phoenix: "Rubber? Fire Fist Gun!" His fists were flaming, and he started a fierce battle with the flaming phoenix. Zoro wielded three swords, and the sword lights flashed in the flames: "Three Swords Style? Flame Wave Slash!" His attacks intertwined with the flames.
