After discussing their plan at the coffee shop, Conan and Lin Yu decided to take immediate action. They knew that every second was crucial when facing such a powerful and mysterious enemy as the Black Organization.

"Lin Yu, can you use your skills to obtain more details about the Black Organization's cyber virus plan?" Conan asked with a serious expression.

Lin Yu adjusted his glasses, pondered for a moment, and then replied, "I can try, but it's very dangerous. If they find out, the consequences will be unimaginable."

Nevertheless, Lin Yu decided to take the risk. He returned to his secret workshop and once again infiltrated the "Dark Network" system. After several hours of intense work, Lin Yu finally obtained some crucial information.

“Conan, I discovered they’re preparing to conduct the final testing and deployment of the virus in an abandoned factory,” Lin Yu said, panting heavily.

Conan's eyes were determined, and he immediately began to formulate a plan: "We need to go to that factory first to investigate and find out their layout and personnel."

So, Conan and Lin Yu quietly arrived near the abandoned factory. The factory was heavily guarded, with many members of the Black Organization patrolling around it.

"It seems that it won't be easy to infiltrate directly," Lin Yu said in a low voice.

Conan observed for a while and said, "Let's find a secluded place and wait for the right opportunity."

While they were waiting, Ran Mouri called, and Conan briefly told her that he was investigating a case and that she shouldn't worry.

As night fell, the number of patrol personnel at the factory seemed to decrease. Taking advantage of this opportunity, Conan and Lin Yu cautiously approached the factory.

They quietly scaled the wall and entered the factory. The factory reeked of a pungent chemical smell, and was filled with a jumble of machines and pipes.

Suddenly, footsteps approached, and Conan and Lin Yu quickly hid behind a huge machine.

"Don't let them find out." Lin Yu's heart was pounding with nervousness.

Fortunately, the patrol officers did not spot them and continued walking in another direction.

Conan and Lin Yu continued deeper into the factory, where they discovered a laboratory where some people in white protective suits were working busily.

"It seems this is where they conduct virus testing," Conan whispered.

Just then, Lin Yu accidentally bumped into a metal bucket, making a sound.

"Who goes there?" someone in the lab shouted alertly.

Seeing this, Conan and Lin Yu quickly turned and ran away. Members of the Black Organization gave chase.

They fled around the factory, evading the pursuit of the Black Organization.

"This way!" Conan led Lin Yu into a narrow passage.

The passageway was dark and damp, filled with an unpleasant odor.

"We seem to be lost," Lin Yu said anxiously.

Conan calmly said, "Don't panic, we'll definitely find an exit."

Just as they were groping their way forward, a bright light suddenly appeared ahead.

"Watch out! There might be an ambush," Conan warned.

They cautiously approached the light and discovered it was a ventilation opening.

"Climbing out from here might be the way to get rid of them," Conan said.

Lin Yu nodded, and the two of them struggled to climb up the ventilation shaft and finally escaped the factory.

However, their actions have already raised serious concerns within the Black Organization.

“Although we haven’t fully grasped their plan this time, we’ve at least got some clues,” Conan said.

"What do we do next?" Lin Yu asked.

Conan thought for a moment and said, "We need to go back and reorganize our thoughts to develop a more comprehensive plan."

Back at their lodgings, Conan and Lin Yu began analyzing the information they had gathered.

"Judging from the current situation, the Black Organization's virus plan is nearing completion, and we must stop them as soon as possible," Conan said.

Lin Yu frowned: "But their defenses are too tight, making it difficult for us to infiltrate again."

Just when they were in trouble, Ai Haibara brought important news.

“I studied some of the data Lin Yu brought back and discovered a weakness in this virus,” Ai Haibara said.

"Really? That's great!" Conan exclaimed excitedly.

“But to exploit this weakness, we need some special equipment and materials,” Ai Haibara continued.

Without hesitation, Conan said, "No matter how difficult it is, we must find these things."

Over the next few days, Conan, Lin Yu, and Ai Haibara traveled around searching for the necessary equipment and materials.

Ran and Kogoro Mouri were very puzzled by Conan's frequent outings, but Conan only said that he was assisting the police in their investigation.

Finally, they gathered everything.

"Now, it's time to deliver a fatal blow to the Black Organization." Conan's eyes gleamed with determination.

However, unbeknownst to them, the Black Organization had already detected their actions and was setting an even bigger trap for them...
