"No matter what, we must find other entrances to the secret passage now. The missing Wu Di and the others may still be alive. No one can trust the entire castle. They can only rely on us to save them now." Ai Haibara said.

"The Emperor Wu saved me so many times. This time I will save him. I must save Emperor Wu!" Akumi clenched her fists.

Azumi fantasized for a moment, and she rescued Emperor Wu, the princess saved the hero, and then the two lived happily together.

The castle was very large. Haibara Ai and others checked each room and came to a studio. It was a place where nobles and young people practiced painting. The room was very spacious and there were many plaster statues placed.

"There are a lot of newspapers here." Ayumi found a pile of newspapers in the corner.

"Newspapers are used to wrap paintings and clean brushes." Mitsuhiko has the specialty class of newspaper painting and knows some relevant common sense.

"The news on these newspapers is so old." Ai Haibara looked at the newspapers and found that these newspapers were from a few years ago, and even about a fire in the castle tower four years ago.

"Xiao Ai, Mitsuhiko is gone." As Ai Haibara was reading the newspaper, Ai Mi said in fear.

Ai Haibara and Ayumi found a door open, which was the entrance to the fire tower, but the gate that should have been blocked was wide open at this time.

"There may be danger inside. I'll go in and see. You stay outside and hide it. No matter what happens, don't expose it, and don't come in. If you count three hundred numbers and I haven't come out yet, you can run away quickly. Don't go back to the castle and run along the lane in the forest. If you are lucky, you should be able to wait for rescue." Ai Haibara reminded Ai Ai to Arima.

Afterwards, Ai Haibara walked into the tower and Ayumi hid alone in the nearby grass.

"I'm counting to three hundred, Xiao Ai." Ai Mi counted three hundred times, walked out of her hiding place, looking at the gate of the tower. The gate was still closed, and Haibara Ai did not come out of the tower.

According to Ai Haibara, if she had not come out after three hundred numbers, Ayumi should have escaped and escaped from the castle, but Ayumi, who was standing in front of the tower gate, was very hesitant.

"I can't escape or something, I can't escape, I still have to save Emperor Wu." Akumi gritted her teeth and walked into the tower.

"Xiao Ai, where are you?" Ayumi turned on the watch and flashlight and walked upstairs.

A black shadow heard Ai Mi's voice and followed, but couldn't find Ai Mi. He checked everywhere, and even checked the secret passages of the mechanism in the tower, but he didn't find Ai Mi.

"Have you heard me that I asked you to escape? If I hadn't happened to be in this secret passage, you would have been killed long ago." Haibara Ai used other sounds to lead the black shadow away. Haibara Ai and Ai Mei came out of the secret passage, and Haibara Ai said.

"Because something might happen to everyone, I can't just run away by myself. It's great, you're fine." Ayumi hugged Ai Haibara in a crying voice.

"Ah, you're such a hopeless child. Forget it, wipe away your tears quickly. We're going to find everyone." Haibara sighed and patted Bumi's back.

"That person just now should be the one who attacked Emperor Wu and the others. I don't know where he hid Emperor Wu and the others." Haibara Ai came to the underground secret room at the bottom of the tower, and there was a secret passage next to it. The direction should be to the castle.

But in the secret room at the bottom of the tower, they did not find Wu Di and others, but found a white bone.

"It has been turned into a skeleton for a long time. Judging from the dust on his body, he should have just moved here not long ago. Maybe at the bottom of the secret passage in the castle, the words engraved by this person on the steps." Ai Haibara said.

During the day, the bones that Emperor Wu and Conan saw were this one. In order to prevent others from discovering it, the black shadow moved the bones here.

"This white bone was a woman during his lifetime, and her legs were much thinner than other bones, and her teeth were all lost. Could it be that the identity of this white bone is?" Haibara Ai simply examined the white bones, and a thought suddenly appeared in his mind, and his pupils shrank sharply.

"What's wrong, kids, I heard the sound and came to see the situation. You seemed to have discovered something amazing. By the way, there should be three kids left. There are only two of you here. Where is the other kid? Can you tell grandma?" Suddenly, an old voice sounded from behind the two.

I saw the old woman standing behind the two of them and looking down at them.

"Not good, my friends have all been captured by bad people," Ao Mei said quickly.

"Idiot, run!" Haibara Ai grabbed Ai Ai and ran away.

"Oh? Xiao Ai, we should take our grandma to escape, otherwise our grandma would be attacked by bad people," said Ao Mei.

"What nonsense are you talking about? That person is the one who attacked us. Didn't you see that she was standing just now? The old lady should have paralyzed legs and was unable to move. She was sitting in a wheelchair." Ai Haibara said.

"The bone just now has too thin legs and should have not walked through for a long time. In addition to the shape and age of the bones, the bone is the old lady. The old lady has been killed long ago. That man killed the old lady and pretended to be the old lady. He lived in this castle. He was afraid that his family would find him, so he pretended to be demented."

"It should have been that bag dropped in the fire four years ago, and I was afraid that my daughter would find it, so I burned everyone to death. As long as I know this underground secret passage, I can set fire without being discovered, and then pretend to be an old lady and go back to the castle!" Haibara Ai said.

The murderer who pretended to be the old lady seemed to be sitting in a wheelchair for a long time, not walking frequently, and his legs were not very straightforward, so he did not catch up with Ai Haibara and Arimi.

Ai Haibara and Arimi ran to the end of the secret passage, followed the ladder, pushed the floor tiles away, and appeared in the hall of the castle.

"Hahaha, the purpose of the prisoner disguised as the old lady is probably for the treasure in this castle." Haibara Ai said panting.

"That's right, I came to this castle just for the treasure, but I was discovered by the old woman and almost fired by her. I had to do this bad thing. After all, our voices were very similar." The fake old lady chased after her.

"Don't worry, I won't let you stay in the dark tunnel like that dead old woman. When I knock you out for a few days, you will meet with your friends in the forest and be together forever." The fake old lady raised her iron stick.

"It's so disgusting." Suddenly a voice rang.

"Who is it!" The fake old lady was shocked when she heard the sound.

The next moment, the fake old lady seemed to have slipped her hands, and the iron rod in her hand fell to the ground. While it landed, it twitched on the fake old lady's legs like a coincidence. The fake old lady's legs hurt and she knelt on the ground.
