With valuable evidence of the crime, Conan and his friends immediately cooperated with the police to bring the criminal group to justice.

Based on this evidence, the police quickly launched a large-scale arrest operation. Police cars patrolled every corner of the city, and members of the criminal gang were apprehended one by one.

However, the criminal organization is deeply entrenched, and some remnants remain operating in the shadows, attempting to sabotage police operations.

“We can’t let their plot succeed,” Conan said.

Ran Mouri clenched her fist: "Yes, they must all be brought to justice."

Lin Yu used his high-tech equipment to monitor the criminal group's communication channels, trying to obtain their latest plans.

"I discovered they were preparing to conduct a major transaction at a port, possibly to transfer funds and flee," Lin Yu said.

Conan and the others immediately informed the police, who quickly deployed officers to the port.

When they arrived at the port, the criminal gang was busy making a deal.

"Don't move!" the police shouted.

Upon seeing this, the members of the criminal gang picked up weapons and fought back.

Another fierce gunfight broke out.

Conan and his friends also joined the fight, working closely with the police to gradually suppress the criminal group's firepower.

"Surrender! You have nowhere to run!" Nightshade shouted.

But the criminal gang continues to resist stubbornly.

During the battle, Conan discovers that a key figure in the criminal organization is trying to escape by boat.

"We can't let him get away!" Conan quickly gave chase.

Ran Mouri followed closely behind.

They engaged in a fierce battle with the leader on the ship.

In the end, Conan and Ran Mouri successfully subdued the leader.

With the capture of the last member of the criminal gang, the battle against the gang has finally achieved a complete victory.

The people in the city cheered and expressed their respect and gratitude for the heroic actions of Conan and his friends, as well as the police.

However, Conan and his friends didn't have time to rest, as there was still a lot of follow-up work to be done.

They assisted the police in compiling evidence to ensure that every member of the criminal gang received the legal punishment they deserved.

In court, faced with overwhelming evidence, the members of the criminal group were unable to deny their crimes and were all sentenced to heavy prison terms.

"Justice has finally been served," Ai Haibara said.

But they know that the path to upholding justice will never end.

Soon after, a series of strange thefts occurred in the city.

"It seems a new challenge awaits us," Conan said.

Ran Mouri smiled and said, "Then let's face the challenge together."

Lin Yu and Ye Ying also readily agreed to participate in the investigation.

They began gathering clues and interviewing victims, gradually discovering that these thefts were not ordinary thefts, but seemed to be hiding a larger conspiracy.

During the investigation, Conan discovered that the methods used in these thefts were very similar, and the stolen items all had special value.

"These items seem to have been stolen for a specific purpose," Conan analyzed.

Ai Haibara nodded in agreement: "I feel the same way, but what is the purpose?"

Their investigation deepened, and they discovered that the stolen items were all related to an ancient legend.

It is said that collecting all these items will unlock a mysterious treasure.

"Could it be that someone orchestrated this series of thefts for the sake of this treasure?" Lin Yu said.

Conan frowned: "It's very possible, but the veracity of this legend remains to be verified."

They decided to start their investigation from the source of the legend.

After some effort, they found an old man who knew about the legend.

The old man told them, "This legend has been around for a long time, but no one has ever actually found that treasure."

Conan asked, "Do you know the specific connection between these stolen items and the treasure?"

The old man pondered for a moment: "It is said that these items are the keys to unlocking the treasure, but the specific method has been lost."

Conan and the others fell into deep thought.

Just then, they received news that another batch of items had been stolen.

“We must speed things up; we can’t let the criminals get away with it,” Nightshade said.

Following the new clues, they tracked down an abandoned factory.

A mysterious atmosphere permeated the factory, sending chills down one's spine.

"Be careful, there might be danger here," Conan warned.

They cautiously entered the factory and suddenly heard a strange noise.

"What was that sound?" Ran Mouri asked.

Before they could react, a group of dark figures rushed out from all directions...
