After successfully preventing a terrorist attack, Conan and his friends once again became heroes of the city. However, they had no time to bask in the praise, as their investigation and interrogation of the criminal gang uncovered some unsettling new clues.

In the criminal gang's secret documents, Conan discovers vague references that seem to point to a larger, more mysterious organization that manipulates various criminal activities behind the scenes, with the recently defeated gang being just a small branch of their network.

"This is not good news." Lin Yu frowned as he looked at the few words on the document.

Ai Haibara analyzed, "This mysterious organization is very well hidden; we've never heard of it before."

Ran Mouri said worriedly, "I wonder what other terrible things they're planning."

Kogoro Mouri patted his chest and said, "No matter how strong they are, we cannot back down!"

To learn more about this mysterious organization, Conan and his friends decide to investigate further. They begin visiting the networks of the criminal gang members, searching for possible informants.

After some effort, they found an informant who had previously been in contact with the criminal gang. This informant, fearing retaliation from the mysterious organization, was initially unwilling to reveal much information.

“I can’t tell them, they’ll kill me!” the informant said in terror.

Conan patiently reassured him, "As long as we can bring this organization to justice, you won't have to worry anymore."

At Conan's urging, the informant finally provided some important clues. It turns out that this mysterious organization is conducting illegal transactions involving weapons, drugs, and classified information in an underground location in the city.

Having obtained the clue, Conan and his friends immediately took action. They quietly infiltrated the underground location.

A pungent odor permeated the air, the lighting was dim, and the crowd was mixed. Conan carefully observed his surroundings, while Lin Yu used his device to listen to the conversations around him.

"This batch of goods must be sold as soon as possible."

"Be careful, don't get caught."

Suddenly, they were discovered by a group of guards.

"Who goes there? How dare you trespass here!" the guards shouted.

A fierce chase and battle ensued. Conan and his friends used the terrain and their wits to outmaneuver the guards.

Ran Mouri used her excellent karate skills to defeat the guards one by one.

"Don't let them get away!" More and more guards arrived.

At a critical moment, Conan discovered a ventilation duct, and they quickly climbed inside, temporarily escaping their pursuit.

"It's too dangerous here, we have to find a way out," Ai Haibara said.

Lin Yu looked at the equipment in his hand: "I've found a passage to the outside. Follow me."

However, they encountered new trouble in the passage. The passage was filled with various mechanisms and traps.

"Watch your step!" Conan warned.

Kogoro Mouri accidentally triggered a trap, and a huge rock rolled down towards them.

"Run!" Everyone ran forward as fast as they could.

Fortunately, they managed to avoid the rocks and finally found the exit.

Once back in a safe place, they began to organize the information they had gathered from the operation.

“Although we haven’t directly found the core members of the mysterious organization, we’ve at least learned about some of their activities,” Conan said.

Just then, Conan received a mysterious email. The email warned them not to interfere in the affairs of the mysterious organization anymore, or they would face the consequences.

"It seems they've noticed us," Lin Yu said.

Conan, however, remained unfazed: "The more this is the case, the less we can back down."

In the days that followed, Conan and his friends faced unprecedented pressure and danger. A mysterious organization constantly harassed and attacked them, plunging their lives into chaos.

One day, Ran Mouri was being followed on her way home, but fortunately Conan discovered it in time and repelled the stalker.

"Ran-neechan, are you alright?" Conan asked with concern.

Ran Mouri shook her head: "I'm fine, it's just that these people are going too far."

Ai Haibara said worriedly, "We must find a way to deal with them as soon as possible."

To protect themselves and their families, Conan and his friends decide to go into hiding for the time being while continuing to search for clues about the mysterious organization.

They hid in a secluded cabin, spending their days analyzing clues and making plans.

"I believe that as long as we unite, we will definitely find their weaknesses," Conan encouraged everyone.

In this difficult time, their friendship and faith have become even stronger.

Finally, they discovered the whereabouts of an important member of the mysterious organization.

"This is our chance, we can't miss it!" Conan said.

They quietly followed the member and arrived at an abandoned factory.

The factory was filled with smoke and fraught with unknown dangers.

"Everyone be careful," Conan warned.

They cautiously entered the factory when they suddenly heard footsteps.

"Someone's coming!" Kogoro Mouri said.

They hid in a corner, observing the newcomers.

It turned out to be a conversation between several members of a mysterious organization.

"This plan must succeed; there can be no more mistakes."

"Don't worry, everything is ready."

Conan and the others quietly approached, trying to overhear their plan.

However, at that moment, they accidentally stepped on an aluminum can, making a sound.

"Who?" The members of the mysterious organization immediately became alert.

Another fierce battle broke out...
