After Conan hung up the phone, his friends' expressions all became serious.

"Will this be another tricky case?" Nightshade asked, frowning.

Conan pondered for a moment and said, "Judging from that tone, it probably won't be simple. But in any case, we need to be prepared."

Ran Mouri clenched her fist: "No matter what it is, we can handle it!"

Lin Yu nodded in agreement: "That's right, we can definitely do it together."

Ai Haibara calmly analyzed, "Let's go back and organize our current equipment and clues to see if we can find any useful information."

The group returned to Professor Agasa's house and began preparing for the upcoming challenge.

The next day, Conan received a mysterious package. Upon opening it, he found a strange badge and a note inside. The note read: "Wear the badge and go to the designated location. The truth will be revealed."

"Could this be a trap?" Lin Yu asked worriedly.

Conan examined the badge carefully: "It's possible, but this might be our only clue to the truth. We have to go."

They decided to go together to the location specified on the note, which was a remote, abandoned factory.

When they arrived, the factory was deserted, with only the sound of the wind whistling past.

"Everyone be careful," Conan warned.

Suddenly, the lights came on, and a group of people in black uniforms appeared in front of them.

"You've finally arrived." A voice came from behind the crowd, and a tall man stepped out.

"Who are you? Why did you lead us here?" Ran Mouri shouted.

The man smiled slightly: "I am the leader of this organization. You have ruined many of our plans before. Today, you will not be able to escape again."

Conan calmly said, "Your plot will not succeed."

With a wave of his hand, the leader ordered his men to attack Conan and his friends.

Undeterred, Ran Mouri faced the enemy head-on, her karate moves sharp and decisive, instantly defeating several. Nightshade, on the other hand, used her agility to weave through the enemy ranks, launching unexpected attacks.

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

Ai Haibara observed the situation from the sidelines, searching for the enemy's weakness.

While dealing with the enemy, Conan pondered how to uncover the organization's core secrets.

During the intense battle, Conan noticed that the leader's gaze kept inadvertently drifting towards a corner of the factory.

"There must be something important there," Conan thought.

Taking advantage of the chaos, he quietly approached that corner.

When he arrived, he discovered a hidden room filled with various documents and computer equipment.

"Found it!" Conan exclaimed excitedly.

Just then, the leader noticed Conan's actions and rushed towards him without hesitation.

"Don't even think about succeeding!" the leader shouted.

Ran Mouri and the others arrived in time and stopped the leader.

Conan quickly searched the room for useful information.

"Here's their next move!" Conan shouted.

However, at that moment, alarms sounded in the factory, and the entire factory began to explode.

"Oh no, let's get out of here!" Conan exclaimed.

Amidst the flames and thick smoke, everyone desperately ran out.

When they finally escaped the factory, all that remained behind them was ruins.

"Although we found some clues this time, they still got away," Lin Yu said with some resentment.

Conan looked at the documents in his hand: "But at least we know their plan now. Next, we need to be fully prepared to deal with it."

Ai Haibara said, "These documents need time to be analyzed and interpreted."

The group returned to Professor Agasa's house and began to study the documents in depth.

After several days of effort, they finally discovered some crucial information in the documents.

"So their target was the city's energy core," Conan said.

“If they succeed, the entire city will be paralyzed,” Ran Mouri said.

“We must stop them,” Nightshade said firmly.

Conan devised a detailed plan to prepare for the new battle.

One night, Conan and his friends secretly sneaked into the city's energy core.

The area was heavily guarded, but with their wisdom and courage, they gradually approached their goal.

However, just as they were about to succeed, an accident occurred...
