After destroying the Shadow Alliance's stronghold, Conan and his friends thought they could finally enjoy a period of peace. However, they soon discovered that things were not so simple.

One day, on his way to school, Conan suddenly sensed that someone was following him. He quickened his pace without making a sound, trying to shake off the follower, but the follower was relentless in pursuit.

Conan turned into a small alley and hid around a corner. When the stalker passed by, he suddenly jumped out and subdued him.

"Tell me, why were you following me?" Conan demanded.

The stalker was a haggard-looking man who looked at Conan in terror: "I... I was forced into this. Someone made me spy on you."

Conan frowned: "Who is it?"

The man said, trembling, "I don't know. They're very mysterious. All I know is that they're plotting a bigger conspiracy."

Conan realized the seriousness of the situation, so he handed the man over to the police and then told his friends what had happened.

“It seems the ‘Shadow Alliance’ hasn’t been completely wiped out; they’re still operating in the shadows,” Kogoro Mouri said.

Lin Yu said, "We must find their trail as soon as possible and stop their plot."

Just then, a series of bizarre cases occurred in the city. Several important figures disappeared one after another, and strange symbols were left at the scene.

Conan and his friends begin investigating these cases and discover that the symbols are related to the "Shadow League".

“This is a provocation they’ve given us,” Ran Mouri said.

Through in-depth investigation, they discovered that the "Shadow Alliance" was conducting a horrific experiment, attempting to create a virus that could control human minds.

“If this virus is released, the consequences will be unimaginable,” Ai Haibara said.

Conan and his friends decide to infiltrate the enemy's lair, find the "Shadow Alliance's" laboratory, and thwart their plans.

They disguised themselves as members of the "Shadow Alliance" and infiltrated a secret base.

The base was heavily guarded, with patrol personnel and surveillance equipment everywhere.

Conan carefully avoided the patrol team as he searched for the location of the laboratory.

During their search, they inadvertently revealed their identities and were discovered by the enemy.

"Run!" Conan shouted.

They fled around the base, evading the enemy's pursuit.

Kogoro Mouri was injured during his escape, and Ran Mouri supported him, saying, "Dad, hang in there!"

Lin Yu used his high-tech equipment to interfere with the base's monitoring system, buying everyone some time.

With a grave expression, Conan led the group quickly into a room and gently closed the door. Inside, they found the room filled with all sorts of documents and complex, sophisticated equipment. The documents were scattered haphazardly on the floor and tables, as if hastily handled; some of the equipment was damaged, while others still emitted a faint glow, indicating previous use.

Conan frowned and whispered to the others, "The situation is urgent. We must find a way out of here as soon as possible." As he spoke, he began to carefully search for clues among the pile of debris.

However, at that moment, a series of noisy footsteps approached, followed by the enemy's fierce shouts: "They must be in this room, search it carefully!"

Upon hearing this, Conan and the others' hearts pounded wildly, practically leaping into their throats. Everyone was too tense to utter a sound, holding their breath and silently awaiting their fate.
