Those who wanted to steal the treasure were eyeing the castle covetously, and Conan and the others knew that a fierce battle was about to begin.

"We must prepare our defenses," Conan said with a serious expression.

Lin Yu quickly checked his high-tech equipment: "My weapons can last for a while, but the enemy has a large number of people, so we need to come up with a comprehensive plan."

Ran Mouri clenched her fist: "No matter what, we won't let them succeed."

Ai Haibara calmly analyzed the situation: "The castle's terrain is advantageous to us; we can use this to our advantage."

They began setting traps inside the castle, hanging heavy objects above passageways, preparing to deliver a heavy blow to the enemy when they entered.

Emily also helped prepare the items needed for defense.

Soon, the enemy launched an attack and forced their way through the castle gates.

"Everyone, get ready!" Conan shouted.

When the enemies entered the castle passage, Conan and the others activated the traps, and heavy objects fell, knocking down a group of enemies.

"Charge!" The enemy was not deterred and continued to surge forward.

Ran Mouri charged ahead, using her karate skills to defeat the enemies one by one.

Lin Yu provided weapon support from the rear, and his accurate shooting deterred the enemy from approaching easily.

Conan and Ai Haibara closely observed the enemy's movements and directed everyone's actions.

The battle was fierce, and shouts and sounds of fighting filled the castle.

Conan discovers that several of the enemies are exceptionally skilled and are gradually breaking through their defenses.

"We can't let them get close to the treasure!" Conan said, charging towards the enemies.

After a fierce battle, Conan finally subdued the enemies.

But by this time, they were all exhausted and had suffered injuries to varying degrees.

"This can't go on. Our strength won't last much longer," Lin Yu said, panting heavily.

Just then, police backup arrived.

"Don't move! Drop your weapons!" The arrival of the police threw the enemy into chaos instantly.

With the help of the police, the enemy surrendered one after another, and the castle was finally saved.

"Thank you so much. If you hadn't arrived in time, the consequences would have been unimaginable," Conan said to the police.

“It’s our duty, but you guys are very brave,” the police officer said.

The castle finally returned to its former tranquility, and Conan and his friends relaxed their tense nerves. Everyone breathed a sigh of relief, as if they had just woken up from a terrible nightmare.

"This experience can only be described as thrilling!" Ran Mouri exclaimed, still shaken. Recalling the various dangers and challenges she had encountered, she couldn't help but feel a wave of fear.

Emily gazed gratefully at the brave and fearless people before her, tears welling in her eyes, and said, "Thank you so much. If it weren't for your help, not only would this castle be unable to escape that evil curse, but I myself would probably be in grave danger."

Conan smiled and humbly replied, "Don't be so polite. Helping others solve their problems is our bounden duty." Although he spoke lightly, everyone knew in their hearts that it was no easy feat to successfully resolve this crisis.

Just as everyone began to tidy up the castle, which had been left in a mess, Conan inadvertently discovered a dusty, rather old-fashioned book in a secluded corner. The book was inexplicably hidden there, seemingly insignificant, but Conan's keen intuition told him that it must contain some important clues or unknown secrets.

As he carefully turned the pages, lines of ancient and mysterious text came into view. As he read on, Conan's expression gradually grew serious…
