Conan and the others quietly sneaked into the basement, which was dimly lit and filled with a somber atmosphere.

They carefully avoided any debris that might make noise and gradually approached the figures who were talking.

"Don't act rashly yet, let's see what other plans they have," Conan said to his companions in a low voice.

The group nodded, hiding in the shadows and listening to the enemy's conversation.

"That mysterious person has disappeared. If he gets caught, we're all doomed," a slightly panicked voice said.

"What's there to be afraid of? As long as we guard this place and wait for the organization's next instructions, we'll be fine." Another voice sounded more composed.

Ran Mouri clenched her fists, wishing she could rush up and subdue them immediately, but Conan stopped her with a look.

At that moment, one of them got up, seemingly preparing to go to another room. Conan and the others took the opportunity to quietly follow.

They entered a room filled with files, and the man was rummaging through something on the table.

"Now!" Conan gave the order, and everyone rushed in.

The man was startled by the sudden attack and was subdued by Ran Mouri before he could react.

"Tell me, where is that mysterious person?" Conan pressed.

"I don't know, I really don't know!" the man replied in terror.

Lin Yu searched the room for useful information, while Night Shadow guarded the door to prevent anyone else from entering.

Ai Haibara discovered an encrypted file and frowned: "This might be the key, but it will take time to crack it."

Conan looked at the subdued man and said, "You'd better tell the truth, or you'll face the consequences."

The man finally admitted, "I only know that the mysterious person may have gone to another secret base of the organization, but I don't know the exact location."

Just then, footsteps could be heard outside.

"Oh no, we've been discovered!" Nightshade shouted.

Conan made a quick decision: "Take him with us, let's get out of here!"

They desperately fled the basement while being pursued by the enemy.

Once outside, they hid in a nearby grove of trees.

"What do we do now?" Ran Mouri asked.

Conan thought for a moment: "Let's find a safe place first and have Ai Haibara decipher the document. Maybe we can find clues about the mysterious person."

The group walked for a while in the woods and found an abandoned hut.

Ai Haibara immediately began deciphering the file, while the others stood guard outside.

Time ticked by, and Ai Haibara finally cracked the file.

“I’ve got it. The document mentions an address that might be the secret hideout,” Ai Haibara said.

Conan glanced at the address: "Let's not delay, let's set off immediately."

They embarked on their journey once more, arriving at the place mentioned in the document.

This is an ordinary-looking office building, but Conan keenly senses the hidden guards around it.

"Everyone be careful, don't alert them," Conan said.

They quietly circled around to the back of the office building and discovered a hidden entrance.

Conan carefully pushed open the door, revealing a long corridor inside.

Suddenly, the previously pitch-black space was illuminated by bright lights, the light instantly filling every corner. At that moment, a group of guards clad in black armor and wielding sharp weapons appeared before them like ghosts. These guards were tall and imposing, with cold, stern faces, exuding a chilling aura.

"So you really did come." A familiar voice slowly drifted from behind the guards, a voice that seemed to possess an inexplicable magic, causing everyone present to tense up. Then, a figure slowly emerged—the mysterious man who had remained hidden in the darkness. He wore a long black robe, its sleeves fluttering in the wind, and a silver mask concealing only a pair of deep, cold eyes.

"Your end is nigh!" Conan shouted angrily, his eyes wide, gripping his sword of deduction tightly, pointing it at the mysterious man. His voice was firm and powerful, filled with justice and determination.

However, faced with Conan's angry rebuke, the mysterious man merely laughed disdainfully. His laughter echoed throughout the space, like the hooting of an owl, sending chills down everyone's spine. "You bunch of overconfident fools? You think you can stop my plan? You're just dreaming!" The mysterious man's words revealed unparalleled arrogance and confidence.

As the mysterious figure finished speaking, the atmosphere between the two sides instantly became extremely tense. A fierce battle seemed imminent...
