What's wrong with me who owns the system in Conan?

"Actually, the child's father has often heard about this matter before, but he is not angry at all when he hears such things, but is very happy!"

"I'm sorry, I shouldn't let the eldest lady think of these things again."

"You don't have to be nervous!" The eldest lady glanced at the photo on the wall, "I've long been used to living here without him, it's the same as the change in the pattern of banknotes and the size of a passport."

"I was not used to it at first, but after a long time, I felt nothing strange."

"Time is indeed a scary thing, regardless of joy, anger, sorrow, or joy, it will disappear with time."

Mamiya Zenoyo seemed to have just seen it, and then asked Fengyuan and the others next to him: "By the way, who are these?"

"Ah~ They are the master's friends. This is the young master of the Kondo family, and the one next to him is a scientist." The housekeeper introduced Fengyuan and Dr. Ali to her.

"Oh~ I'm really rude!" Mamiya Zoyo said again with joy, "Scientists should be very smart!"

"Then I want you to help us solve the mystery and see what mystery he has buried in this castle!"

"Mystery?" Everyone was puzzled.

"Yes, when he was dying, he once said such a sentence!" The gardener explained for several people, "He who solves the mystery of the castle, he will give him his most precious treasure!"

After listening to these words, Feng Yuan also roughly understood what the main line of the system's mission is.

Moreover, he seems to have a little impression of this plot, but because he has watched it for too long, he only vaguely remembers that this eldest lady is not a good person.

Soon, Kaede Kondo saw Mamiya Zoyo look crazy, and then slid the wheelchair away.

"Hey, Uncle, I wonder if there is a room where you can directly see the chessboard in the yard?" Conan asked the gardener beside him.

The gardener glanced at Fengyuan and Dr. A Li, and seeing that they had nothing to say, he walked towards the third floor, "Come with me!"

Then the gardener took Conan and the others to the front, while Feng Yuan and Dr. A Li were familiar with the surrounding corridors behind.

"It's not good, Conan disappeared in the blink of an eye!" At this time, Ayumi and the others shouted from the next room, and Fengyuan and the others hurried over to check.

"What's going on?" Feng Yuan stepped forward and asked.

"Conan was still here just now, but he disappeared in a blink of an eye!" Ayumi looked at Fengyuan sadly and explained.

"Should it be the clock?"

"What?" Feng Yuan looked at Xiao Ai suspiciously.

"Just now, when I came over, this chair and these books fell to the ground, but Conan disappeared in a blink of an eye."

"I think there should be some secret passage behind here?" Xiao Ai looked at the few people present indifferently.

"Mr. Jiangong, don't you know if there is any secret passage nearby?" Feng Yuan looked at the nobleman Jiangong who had just rushed over, "Because the child may be in danger by himself, it's better to find it early."

"This~ I don't know too well, but maybe you can look it up yourself."

"Sorry, let's look for it!" Feng Yuan looked up at the clock in front of him, "Xiao Ai, is this the one?"

"Well, I think it should be adjusted to a specific time, and then the secret passage will be opened." Because Fengyuan was by the side, Xiao Ai had nothing to worry about.

"Then let's try it!" After Feng Yuan finished speaking, he moved the pointer on the dial with his fingers.

"Whoo~"

The moment the pointer passed twelve o'clock, the wall rolled over in an instant, Feng Yuan smiled and looked at the crowd, "I found it."

"Then let's go find it together!" Kojima Motota jumped up and looked at the crowd excitedly.

"I'm going, I'm going, Black Conan will be very scared down here by himself!" Ayumi rushed forward eagerly.

"Is there a flashlight?" Dr. A Li turned around and asked Mr. Gamiya.

"Oh, wait a minute, I'm going to get it now!"

"Yuentai, Mitsuhiko, Ayumi... you troublesome kids!" As soon as Dr. Ali's voice fell, even several children rushed into the secret passage.

"In that case, you can stay up there to meet the doctor. I'll go down to find them first." Kondo Fengyuan turned to look at the doctor.

"Oh~ I'll trouble you, Mr. Kondo." Dr. A Li looked at Feng Yuan hesitantly and said.

"Ah."

Feng Yuan nodded, and then walked into the passage first, and Xiao Ai also followed after seeing this.

"Wow~ It's so dark in here."

"Fortunately, we have the lighting equipment given by the doctor!"

"Yes, but where did Conan go? Why can't he be found everywhere?"

"Hey! Why are you little ghosts so impulsive?" At this time, Kondo Fengyuan and Xiao Ai also caught up with them.

"Oh~ it's Brother Fengyuan!"

"It really scared us!"

"Did you find anything?" Feng Yuan looked at the few people and asked with a smile.

"No……"

Tears welled up Ayumi's eyes.

"Don't worry, that guy won't be so easy to get into trouble." Xiao Ai said calmly from the side.

"Okay, let's continue to look forward!" Feng Yuan interrupted the words of several people, and then took the lead to walk forward.

"This is?"

"What's written there!"

Fengyuan and Xiaoai stepped forward to check by the light of a few children's flashlights.

"That person is taking my place now, and wants to snatch the treasure in the castle..."

"You should want to talk about treasures later, right?" Xiao Ai looked at Feng Yuan and said calmly.

"Ah."

Feng Yuan nodded, "It should be like this, and the notch should have been engraved for a while."

"So who would have carved this?" Mitsuhiko asked doubtfully.

"It should be the eldest lady!" Feng Yuan smiled and turned to look at them.

"what!"

"That Obasan?"

"If I'm right, the only one who will be replaced is the eldest lady." Feng Yuan looked at the little carrots confidently and said.

"Huh? There seems to be blood here!" Yuan Tai, who was wandering around, suddenly squatted in an open space and shouted at them.

Xiao Ai leaned forward to take a look, then touched it lightly with her fingertips, and then took it to her eyes for a closer inspection.

"It's blood, and it's just fresh blood."

"Could it be Conan's?" Mitsuhiko asked in horror.

"It's very possible!" Xiao Ai got up and looked at Fengyuan, "There may still be some danger here."

"It's okay, it's just a villain who hides his head and shows his tail. Maybe the person pretending to be Mamiya Masuyo is following in the secret passage! But the one who has me here may not dare to come out."

Feng Yuan smiled, and then led several elementary school students to continue exploring in the secret passage.

"Ah~"

"There are dead people!"

"Stop shouting, it's just a skeleton." Feng Yuan stepped forward and squatted down, examining the dried corpse.

"There's not much dust on the skeleton. It should have been moved by someone just now. This person should be the one who left those marks. As for the person who moved her here, it should be Conan!"

"And it seems that my guess is correct." Feng Yuan checked the skeleton and said to the crowd behind him:
"Look, her teeth have basically fallen out, her feet are short, and her hair is long. She is clearly an older woman, and the only person in this family who fits all of them should be Mamiya Masuo."

"But why did that person have plastic surgery to look so ugly?" Yuan Tai asked puzzled.

"It should be the treasure in this castle!" Xiao Ai explained to him, and then said again after recalling what he had seen and heard during the day, "The person who replaced the eldest lady should also be in this castle if he guessed correctly. People in the house!"

"Otherwise, I think, she shouldn't have fooled everyone so easily and successfully pretended!"
