After Conan and his friends discovered the secret that the chemical plant's experiments were related to a new type of chemical weapon, they realized the gravity of the situation. They decided to continue investigating along this lead and bring the mastermind behind it all to justice.

By analyzing some cryptic information in the documents, Conan deduces that it may be related to a mysterious research company in the city. This company appears to be engaged in legitimate research projects, but all indications suggest that it is hiding a dark secret.

In order to gather more information, Conan decides to risk infiltrating this research company.

"Conan, this is too dangerous. Let's think this through carefully," Ran Mouri said worriedly.

"Time is of the essence. If their plan succeeds, the consequences will be unimaginable," Conan replied firmly.

One night, Conan, with the help of high-tech equipment developed by Lin Yu, successfully bypassed the research company's security system and infiltrated the company.

The company was quiet, with only a few emergency lights casting a faint glow. Conan cautiously moved through the corridors, searching for any potentially useful clues.

He entered an office and found some research reports on chemical weapons on the desk. Just as he was about to examine them closely, he suddenly heard footsteps.

Conan quickly hid under the table, his heart pounding.

"This experiment must succeed, or we're all doomed," a voice said.

"Don't worry, everything is under control," another voice replied.

After the two people left, Conan crawled out from under the table and continued searching for clues in the office.

He discovered a hidden safe and, after some trial and error, successfully cracked the code. Inside the safe was a list of people involved in chemical weapons research, as well as some transaction records.

"With these, we can uncover their conspiracy," Conan thought to himself with delight.

However, just as he was about to leave, he accidentally triggered the alarm system.

"Oh no, we've been discovered!"

The entire research company was immediately brightly lit, and security guards rushed towards Conan's location.

With his agility and familiarity with the terrain, Conan outmaneuvered the security guards at the company.

"We must catch him!" the security guards shouted.

Meanwhile, Ran Mouri, Lin Yu, and Ai Haibara were waiting outside the company. Hearing the alarm, they knew Conan was in danger.

"We have to find a way to help Conan," Ran Mouri said anxiously.

Lin Yu used his equipment to interfere with the company's surveillance system, creating an opportunity for Conan to escape.

Conan seized the opportunity to escape the company and reunite with his friends.

"Run!"

They got into the car and quickly left the scene.

Once back in a safe place, Conan will share the clues he found at the research company with everyone.

“The people on this list are all key figures; we need to investigate them one by one,” Conan said.

They began tracking and investigating the people on the list. In the process, they discovered that these people frequently met in a secluded warehouse.

“This warehouse must be an important stronghold for them,” Kogoro Mouri said.

In order to find out what's going on in the warehouse, Conan and his friends decide to take another risk.

Under the cover of night, they quietly approached the warehouse. The warehouse was heavily guarded and surrounded by many soldiers.

"How do we get in?" Ran Mouri asked.

Lin Yu took out some miniature drones: "I can use these drones to scout out the situation inside."

The drone quietly flew into the warehouse, and through the transmitted images, they discovered that the warehouse was filled with raw materials for chemical weapons and some equipment being assembled.

"We must stop them as soon as possible," Conan said.

Just as they were about to take action, they were suddenly surrounded by a group of people.

"How dare you cause trouble here!" said a man who appeared to be the leader.

"Your plot will not succeed!" Conan shouted.

A fierce battle broke out.

Conan and his friends engaged in a fierce battle with the enemy. Ran Mouri's karate skills were astonishing, Lin Yu's high-tech weapons were unpredictable and difficult for the enemy to defend against, while Ai Haibara assisted from the sidelines, providing support for everyone.

During the battle, Conan discovered the enemy's weakness and led everyone in a fierce attack.

After a fierce battle, they finally defeated the enemy and took control of the warehouse.

However, they also knew that this was only part of the enemy's plot, and a greater crisis was yet to come...
