Conan, carrying the old diary, eagerly sought out Ran Mouri, Ai Haibara, Yoru, and Lin Yu. When he recounted the diary's contents about the mysterious island and the mysterious fruit, a flicker of surprise and curiosity crossed each of their eyes.

"A mysterious fruit that can grant superpowers? That sounds incredible." Ran Mouri's eyes widened, filled with doubt.

"But at the same time, the island is shrouded in a curse, which must hide a complex secret." Ai Haibara crossed her arms, her expression serious.

Nightshade frowned slightly, pondered for a moment, and then said, "In any case, we cannot sit idly by when something that could have such a huge impact."

Lin Yu excitedly rubbed his hands together: "Wow, another new adventure! Maybe we can unveil the mystery of this island."

Conan nodded, his gaze resolute: "That's right, we must investigate this thoroughly and not let this mysterious power be exploited by those with ill intentions."

So they began preparations for their journey to the mysterious island. First, Conan gathered information about the island through various channels. He consulted numerous historical documents and nautical records, and even contacted some veteran sailors who had previously sailed in that area. However, information about the island was scarce; all that was known was that it was located in a mysterious sea area, and strange weather phenomena frequently occurred around it.

Ai Haibara used her knowledge to prepare various tools and medicines to deal with potential dangers. She carefully packed antidotes, first aid supplies, and special detection instruments into her backpack, and also tested and upgraded some high-tech equipment to meet unknown challenges.

Ran Mouri and Yoruichi focused on physical training and combat skills. They dedicated time each day to intensive karate and hand-to-hand combat training to improve their fighting abilities and prepare for potential dangers.

Lin Yu utilized his expertise to make a series of improvements to his high-tech equipment. He developed a new type of communicator with stronger signal reception and encryption capabilities, ensuring that their communication on the mysterious island would not be interfered with. In addition, he also created some small reconnaissance robots to detect situations in advance in dangerous environments.

After a period of intense preparation, they finally embarked on their journey to the mysterious island. They sailed on a sturdy rented sailboat, cutting through the vast ocean. The sea breeze howled, and the waves crashed against the hull with tremendous roar.

During the voyage, the weather gradually worsened. The once clear sky was covered with dark clouds, and the waves grew higher and higher.

"Looks like we've encountered a storm." Conan looked at the sky, his brow furrowed.

The captain, an experienced sailor, shouted, "Hold on tight, we have to find a way to get through this storm!"

Following the captain's instructions, everyone quickly secured the ship's cargo, preparing for the storm. Ran Mouri and Nightshade helped raise the sails and adjust the course, attempting to use the wind to stabilize the vessel. Lin Yu, meanwhile, used his high-tech equipment to monitor the weather changes in real time, providing information to the captain.

Ai Haibara and Conan were inside the ship's cabin, checking that all the equipment was functioning properly. Suddenly, a huge wave crashed in, causing the ship to rock violently and some items to fall from the shelves. Conan and Ai Haibara clung tightly to the stable objects around them to avoid falling.

"This can't go on. We need to find a safe place to take shelter from the storm," Conan said.

Just then, Lin Yu called out through the communicator, "Conan, I've spotted a small island ahead. Maybe we can go there to take refuge."

The captain immediately changed course and headed towards the island. Battling through raging winds and towering waves, the ship struggled to approach the island. Finally, they successfully docked in a bay near the island.

The group disembarked and found the island to be deserted but lush with vegetation. They followed a path deeper into the island, searching for a place to shelter from the storm.

Suddenly, Nightshade heard a strange sound. "Listen, what's that sound?"

Everyone stopped and listened intently. The sound was like a deep roar, coming from deep within the woods.

"Be careful, there might be danger," Conan said, signaling everyone to stay alert.

They cautiously approached the source of the sound, parted the dense grass, and discovered a huge beast trapped in a snare. The beast was covered in long brown fur, the size of an adult brown bear, but with sharp fangs and claws.

"What kind of animal is that? It looks so fierce," Ran Mouri whispered.

Conan observed the traps and the wild animals, discovering that the traps were man-made, and that there were strange symbols around them. "It seems this island may not be as simple as it appears; someone has set a trap here."

Just then, another set of footsteps sounded. Conan and the others quickly ducked to the side, and saw a group of people dressed in strange clothes approaching. These people carried spears and bows and arrows, and their expressions were wary.

"Who are you? Why are you on our island?" the leader asked in a broken tongue.

Conan tried to communicate with them in simple language: "We were just passing by when we encountered a storm and came here to take shelter. We mean no harm."

The group exchanged glances, seemingly discussing something. After a while, the leader said, "Alright, since you mean no harm, we can take you somewhere to shelter from the storm. But remember, don't wander around the island; it's dangerous here."
