Chapter 504: Rainbow Bridge: A Fantasy Puzzle-solving Journey of the 7 Mysterious Doors

In the following voyage, they encountered new challenges. One day, they found a huge rainbow bridge appeared in the sea ahead, spanning the entire sea surface, connecting two unknown worlds.

Luffy looked at the Rainbow Bridge excitedly: "Wow, what is that? Let's go and see!" The companions were also full of curiosity, and they drove towards the Rainbow Bridge. When they approached the Rainbow Bridge, they found that there were various mysterious symbols and lights on the bridge, which seemed to be guiding them in the direction they were going.

They boarded the Rainbow Bridge and walked along it. As they walked, they felt a mysterious force influencing them, which made their bodies light as if they could fly in the air.

However, in the middle of the Rainbow Bridge, they encountered a huge level. The level consisted of seven colorful doors, each of which was engraved with mysterious patterns and words. There was an ancient stone tablet in front of the door, which read: "Only by solving the puzzle of the seven doors can you pass the Rainbow Bridge and reach the new world."

Luffy and his companions looked at the seven gates, full of the desire for challenge. They began to study the puzzles on the gates. The puzzles on each gate were different, some were about astronomy and geography, some were about ancient legends, and some were about mysterious magic...

Luffy and his friends give full play to their wisdom and knowledge and start to solve the puzzle. They encounter many difficulties in the process, but they never get discouraged, encourage each other and work together to find the answer. This time, they will start a new journey full of mystery and challenges, and move towards an unknown world.

Luffy looked at the seven colorful yet mysterious doors in front of him, his eyes flashing with excitement: "No matter what the mystery is, we can solve it!"

They first came to a door with stars and constellations engraved on it. The puzzle of this door seemed to be related to astronomy. The constellations on the door flickered, as if telling them an ancient secret. Usopp carefully observed the arrangement of the constellations, scratched his head and said, "These constellations look a little familiar, but a little strange. Their positions seem to be different from what we usually see."

Nami took out her own nautical chart, which also had some constellation markings on it. She compared them and said, "Look, the constellation patterns here seem to be arranged according to a certain point in time. Could it be a special moment related to astronomical phenomena?" Everyone nodded and began to recall the astronomical knowledge they knew.

Robin walked to the door and gently touched the pattern on it: "The lines connecting these constellations seem to have a mystery, perhaps an ancient star map code." After some research, they found that the lines connecting these constellations pointed to a specific location in the sky, and that location had experienced a rare interstellar intersection in history.

Luffy jumped up excitedly: "I know! It's that super rare interstellar intersection moment. We need to input this time into the mechanism on the door." Usopp adjusted the mechanism on the door based on everyone's inference and input that special time. With a flash of light, the door engraved with constellations slowly opened.

They walked into the door, and inside was a space full of starlight, with projections of various constellations flickering on the walls. In the center of the space, there was a crystal ball emitting a soft light, and the crystal ball seemed to contain the mysteries of the universe. Luffy was about to reach out and touch the crystal ball, but was stopped by Ling Tian: "Don't touch it yet, this may be the key clue to pass the next door, we have to be careful."

They walked out of the door with the crystal ball and came to a door with ancient legends. The door was painted with various mythological creatures and heroes fighting scenes, which looked very spectacular. Chopper looked at the patterns on the door curiously: "These paintings look so powerful, just like in a storybook."

Sanji looked at the pattern and analyzed, "These legends should have a certain order. We have to find the connection between them to solve the puzzle." Everyone began to carefully study the legends represented by each pattern and found that these legends all revolved around one theme - courage and sacrifice.

Zoro looked at a pattern on the door that showed a hero fighting a dragon and said, "This hero challenged the dragon alone in order to protect his people. His courage is the key. We may need to arrange them according to the degree of courage reflected in these legends." So they began to discuss the courage of each legendary character and rearranged the pattern in order from high to low.

When the position of the last pattern was determined, the door made a roar and slowly opened. Inside the door was a huge library, with bookshelves full of ancient books, each of which recorded a forgotten legend. On the central table of the library, there was a key shining with a strange light, and on the key was engraved a mysterious symbol similar to the next door.

They picked up the key and walked towards the next door with a mysterious magic pattern. The door was surrounded by a mysterious magical atmosphere, and the pattern on the door kept changing, making people dazzled. Franky looked at the magic circle pattern on the door and said, "This looks like a complicated magic seal. We need to find the right magic spell to unlock it."

Brook walked to the door and felt the magical aura: "This aura is a bit familiar, it seems to be similar to some magical power we encountered before." Everyone began to recall their previous adventures, trying to find clues related to it. Suddenly, Luffy remembered the magic runes he encountered on a mysterious island. Those runes had some similarities with the patterns on the door.

They tried to combine possible magic spells based on the runes in their memory. After many attempts, when Luffy shouted a specific spell, the magic circle on the door shone with a strong light, and the door slowly opened. Inside the door was a room full of magical energy, in which various magic props and an ancient magic scroll floated.

Robin picked up the magic scroll and interpreted its contents: "This records a powerful magic that can break the illusory barrier. This may help us in the challenges ahead." They put away the magic scroll and continued towards the next door.

The puzzle of this door is about geography. There are various landforms and topography patterns engraved on the door, as well as some unclear maps. Nami said excitedly: "I am good at this. We need to find out the places represented by these maps and connect them according to certain rules."
