"This staircase is so long!" Conan muttered to himself. The flashlight in his hand kept shining on his feet to avoid accidentally falling.

"Huh?" When the flashlight illuminated a platform, Conan felt slightly relieved.

"I thought there was really no end to the steps... This is it!" Conan just breathed a sigh of relief, but when the flashlight beam caught an object, his heart suddenly jumped up again.

What is that!

Conan ran down a few steps and suddenly felt something kicked. When he shined a flashlight on it, he could not help but take a breath of cold air and break out in cold sweat.

This is a... human skeleton!

"Most of them have turned into white bones. It seems that they have been dead for a few years." After calming down, Conan squatted down and looked at the long white hair that remained on the skeleton, "Woman? Why does she look familiar..."

"This...!"

In the darkness, behind Conan, a darkness quietly invaded. When he was unconscious, a black shadow with a strong wind hit Conan hard on the back of the head!

……

"Hey, how can you move around?"

Just when Haiyuan put the books back on the bookshelf and stepped on the chair to play with the pointer, he was stopped by a loud shout from behind.

"..." Haibara pursed his lips, looked at the noble Mamiya behind him, exchanged glances with Qian Yu beside him, and climbed down from the chair helplessly.

"Did the children do something?" Dr. Ali came over and asked.

"No, it's just a little prank." Mamiya Takato smiled and shook his head.

"A prank?" The doctor looked at Ayumi and others in confusion.

"No, because Conan is missing!" Ayumi said loudly, "We are looking for him."

"Gone?" The doctor became even more confused.

Qian Yu remained silent, but looked at everyone with sharper eyes.

"I think he probably went to the bathroom, right? It's just downstairs." Tabata Teng'o smiled behind Dr. Agasa.

"Let's go over and take a look." Mamiya Takato suggested.

"Yeah." In desperation, everyone had no choice but to follow.

"Go to the bathroom?" As he went downstairs, Qianyu sneered, "Are you kidding me? That kid disappeared behind me, could he teleport?"

"That room... there must be a problem." Haiyuan said calmly.

"This camping trip is really interesting!" Qianyu suddenly laughed, "Sure enough, as long as you are alive, every day will be full of surprises."

Haiyuan didn't speak, just pursed his lips.

She has seen this smile before.

The roof of the shrine where the fire shines.

……

"No." Looking at the empty bathroom downstairs, Qianyu smiled mockingly.

"Isn't this child here?" Mamiya Takato was also stunned, and then smiled, "Really, where did the child go!"

"Are there any other bathrooms?" Dr. Ali asked.

"This place is rarely used, so there is only one bathroom." Mamiya Takato shook his head.

"Could it be," Yuantai said suddenly, "that guy is hiding somewhere and wants to come out to scare us?"

"It's possible because Conan's temper is very much like that of a child." Mitsuhiko also thinks so.

"Yes, yes."

After finishing speaking, Ayumi, Genta and Mitsuhiko all laughed.

"..." Qian Yu rubbed her hair with a headache.

"Children are really carefree!" Haiyuan looked at the figures of the children and said calmly.

"Aren't you also a child now?" Qianyu shook his head and focused his attention on Conan's whereabouts again.

"Old castle..." Qianyu touched his chin and suddenly burst into laughter, "Could it be..."

"Sir, dinner is ready." While everyone was speculating on Conan's whereabouts, a servant walked up to Mamiya and said to him.

"That's it." Mamiya Takato smiled, turned around and said to Dr. Agasa and others, "Do you want to have dinner with us?"

"But we haven't found Conan yet!" Ayumi said slightly worried.

"It doesn't matter." Mamiya Takato said with a smile, "If that child is hungry, he should appear on his own!"

Qian Yu's face was calm, and there was no trace of what was going on in her heart.

......

"It looks really good." Haiyuan said lightly while biting the food on his fork. As expected of His Highness Ai, he even eats with unusual grace.

"You should be more vigilant than these guys." Qian Yu smiled helplessly and took a bite of the steak on the fork.

"This place hasn't been so lively for a long time, and it feels really good!" Mamiya said with a smile on his face.

"Yes!" Mamiya Takato agreed, "Since mom died, there have been no guests here for a long time."

"Uh, by the way, why have you stayed here and never gone out since my wife passed away?" Dr. Ali asked doubtfully.

"I actually plan to come here to live after graduating from university." Mamiya Takato said with a smile.

"What I said was actually to comfort the mother who lost her daughter," a hint of sadness flashed across Mamiya Mitsuru's face, "But later on, I gradually fell in love with it."

"Humph! That sounds so nice!" A cold snort came from the door. Everyone turned around and saw that it was the old lady pushing the wheelchair.

"Grandma!" Noble Mamiya called out softly.

"You just stayed here for the treasure in the castle, right?" The old lady looked at Mamiya Mitsuru mockingly.

"Treasure?" Qianyu raised his eyebrows, and some long-standing memories in his heart were slowly reviving.

"It doesn't matter if you say so!" Mamiya Mitsuru smiled helplessly, "It would be a lie to say that I don't care about my father's last words before his death."

"Hmph! My daughter would actually fall in love with a greedy person like you!" The old lady snorted coldly, turned around in her wheelchair and walked out, "I will eat dinner in my room! When my daughter comes back, I will definitely

Give her a good scolding!" Then he angrily left in his wheelchair.

"Everyone, don't worry about it." Mamiya Takato said with a wry smile, "Grandma... always thinks that my mother is still alive."

Qianyu looked around and saw that the people around her were not paying attention to her, and left quietly.

"Forget it, let's not talk about it anymore." Mamiya changed the topic and turned to Dr. Ari, "So, have you solved the mystery of the castle?"

"Uh... you're talking about the secret of the treasure in the castle, right?" Dr. Ali touched his beard awkwardly, "This... I don't have a clue yet."

"Chess in the yard." A cold voice interrupted the doctor's embarrassment.

"I think, since it's a secret, there must be a hidden code." Haiyuan gently put down the fork in his hand, "If the courtyard looks like a chess set, the secret should be there too!"
