After Conan discovers that the criminal organization has a mastermind behind it all, he and his friends decide to continue their investigation and will not give up until they bring the perpetrators to justice.

They re-examined all the clues and evidence, attempting to uncover the identity and whereabouts of the mastermind. Lin Yu utilized his high-tech methods to conduct a more in-depth analysis and exploration of the previously obtained information.

"I've discovered some anomalies in the flow of funds, which may be related to the mastermind behind it all," Lin Yu said.

Conan carefully examined these clues and deduced that the mastermind might be hiding on a remote island.

"This island has a complex terrain and is heavily defended. We must be fully prepared," Conan said.

Ran Mouri firmly stated, "No matter how difficult it is, we will go."

Ai Haibara nodded as well: "Yes, we can't let him escape."

With the assistance of Interpol, Conan and his friends, equipped with advanced gear, embarked on their journey to the island.

As they approached the island, they were met with a fierce attack from the enemy. Shells exploded around the ships, creating huge splashes of water.

"Everyone be careful!" Conan shouted.

Ran Mouri and Yu Lin quickly operated their weapons to fight back and cover the ship's advance.

After a fierce battle, they finally landed on the island successfully.

The island is covered in dense jungle and teeming with unknown dangers. Conan and his friends proceed cautiously, remaining constantly vigilant.

Suddenly, a group of enemies sprang out of the woods, engaging them in close combat. Ran Mouri's karate skills proved invaluable at this moment, with each strike knocking down an enemy.

Lin Yu used his technological equipment to release electric shocks and smoke, creating favorable combat conditions for everyone.

Conan, with his keen observation and reasoning skills, directed everyone's actions and avoided the enemy's trap.

During their advance, they discovered a hidden base.

"This should be where the mastermind is hiding," Conan said.

Just as they were about to enter the base, the base gate slowly opened, and a tall, cold-faced man walked out.

“You’ve finally arrived,” the man said.

Conan and the others watched him warily.

"Are you the mastermind behind this?" Conan asked.

The man sneered, "That's right, you think you can catch me? How naive!"

The final showdown has begun.

Ran Mouri was the first to rush forward, engaging the man in a fierce fight. The man was also very skilled, and the two were evenly matched.

Lin Yu provides weapon support to Ran Mouri from the side, while Conan and Ai Haibara take the opportunity to search for a way to enter the base.

The man realized their intentions and tried to stop them.

“You won’t succeed!” he shouted.

Just then, Interpol reinforcements arrived.

"Put down your weapons, you are surrounded!" shouted the commander of the reinforcements.

Seeing that all was lost, the man's eyes revealed despair and resentment.

"Even if you capture me, there will be others who will continue our work!" the man said frantically.

Conan stepped forward: "Your crimes will not succeed; justice will ultimately prevail over evil."

Ultimately, the man was subdued, and the base was taken over by the police.

However, inside the base, they discovered something shocking.

“This is… a new criminal plan!” Ai Haibara said.

It turns out that even after the man was arrested, the criminal group had a follow-up conspiracy brewing.

Conan and his friends decide to continue their investigation and completely destroy the criminal group's plans.

They returned to the city and began investigating the newly discovered clues.

During their investigation, they encountered various obstacles and challenges. Remnants of the criminal organization continued to operate covertly, attempting to sabotage their investigation.

On one occasion, while Conan was searching for evidence in a secret warehouse, he was discovered by the enemy and imprisoned inside.

"Conan!" Ran Mouri and the others anxiously searched for the entrance outside.

The warehouse was filled with toxic gas, and Conan was in great danger.

He tried desperately to find a way to escape while using the communication devices on his person to stay in touch with his companions outside.

"Don't worry, I'll find a way out," Conan said.

Ran Mouri and Lin Yu were desperately searching outside for a way to open the warehouse, while Ai Haibara contacted the police for help.

After some effort, they finally found the warehouse's control device and successfully rescued Conan.

"Thank goodness, you're alright!" Ran Mouri excitedly hugged Conan.

Conan coughed a few times: "I'm fine, let's continue the investigation."

As the investigation deepened, they gradually uncovered the criminal group's new plan.

It turns out they planned to release a deadly virus into the city's water supply, causing widespread panic and chaos.

“We must stop them!” Conan said.

They worked closely with the police to develop a detailed response plan.

On the eve of the criminal group's plan to be implemented, Conan and his friends launched their operation.

They laid ambushes at various key locations, waiting for members of the criminal group to appear.

Finally, members of the criminal group appeared, bringing the virus with them.

"Action!" Conan commanded.

The police and Conan and others quickly launched an operation, engaging in a final battle with the criminal group.

After a thrilling battle, they successfully thwarted the criminal group's plot and seized all the viruses.

The city has returned to peace and tranquility.

Conan and his friends' heroic deeds spread throughout the city, and they became heroes in people's hearts.

"Thanks to you all this time," the mayor personally expressed his gratitude to them.

Conan smiled and said, "It's what we should do."

Having weathered so many storms, Conan and his friends are even more determined to uphold justice. They know that new challenges await them in the future, but they are fearless...
