"Why go to that kind of place alone?"

Kudo Shinichi walked up to Kotomi Wakura at this time and asked.

"I was called out."

A little helpless, Kotomi Kamakura replied.

"Called out? Who is it? ”

Shinichi Kudo continued to ask.

"I don't know."

Kotomi Wakura said, "I just accidentally found a letter in my pocket." ”

"Letter? What's the content? ”

Gao Yuan stepped forward and asked at this time.

"Tell you how you can monopolize your inheritance."

Kotomi Kamakura thought about it and said.

When He Cangyang on the side heard her say this, he said with some disdain: "What." It turns out that it's not me who wants the inheritance, it's Kotomi! ”

"It's not! I never thought of such a thing! ”

Kazukura Kotomi retorted loudly, "However, will calling me out be the murderer who killed Ryoji?" I have clues to the murderer. ”

"What kind of clue, don't you just want an inheritance?"

Yoichi Kazukura said.

"Wait a minute, you two!"

Misa Wakura couldn't listen to it anymore, and said angrily: "Inheritance, inheritance, Dad is not dead yet!" ”

"Hah! I understand! ”

Kogoro, who heard their conversation, suddenly stepped forward and said, "Miss Kotomi, the murderer is you!" ”

In this regard, Gao Yuan shook his head helplessly.

"You killed other heirs in order to monopolize the inheritance, and then disguised the scene of your victimization!"

Kogoro said confidently, "The proof is that you are the only one alive!" ”

"Please wait a minute, if it's for the sake of the inheritance, how do you explain that the first deceased was Mr. Sho Kosaka?"

Kudo Shinichi said.

"Hmph, what's so hard to explain."

Yoichi Kazukura sneered and said, "After all, Dad still wanted to give all the inheritance to that Kosaka Sho!" ”

After saying this, Yoyo Kazukura and Kotomi Kazukura walked away unhappily.

When Gao Yuan heard this, he was a little curious, and asked Misa Wakura, who was still in the living room, "Excuse me, what did you mean by that just now?" ”

"My father had threatened to invest all his fortune in the investigation of the legend of the big bird, but my brother and sister were very opposed to this. At that time, my father said that it would be nice if Mr. Kosaka was his son, and he didn't plan to leave the property to us. It's something like that. ”

Misa Wakura said.

Before entering the Fifteen Nights Village, Takato had a general understanding of the situation of the first deceased, Sho Kosaka, and knew that he was a student who assisted Kazukura Yongkai in investigating the legend of Otori, and now that he heard this, Takato was a little curious, so he asked.

"That said, your father is very interested in the legend of the big bird in this village. What are the results of the investigation? ”

"I don't know. However, there may be some information in my father's study. ”

Misa Wakura said.

In this regard, Kudo Shinichi was also very interested, so, under the leadership of Misa Wakura, Takato and Kudo Shinichi entered Wakura Yukai's study.

This is the second time that Shinichi Kudo has come to the study, and last time he only checked the books here in order to investigate the symbolic meaning of the fragments. After Gao Yuan came in, after roughly scanning the books on the shelves, he went straight to the desk and began to rummage through the drawers of the desk.

"What do you think, Mr. Wise?"

Kudo Shinichi couldn't help but ask when he saw Takato's purposeful behavior.

"The murderer killed people with legends, and the deceased were all people related to the Wakura family, and it just so happened that Chairman Wakura was very obsessed with legends. Don't you think there's any connection between Nao-nao? ”

Gao Yuan said, from the bottom to the top, opened one drawer after another, and then in the top drawer, he found something unusual - an ancient mirror!

Takato took it out, and when Kudo Shinichi saw the style of the ancient mirror, he suddenly showed a very shock, and then took out the three pieces of fragments he found at the scene.

The three pieces Kudo had obtained were just enough to fit into a three-quarter disc, and in the middle of the back of the disc was a protruding buckle-like thing.

Gao Yuan looked at the ancient mirror in his hand and found that there was a recess in the center of the back of the ancient mirror.

Gao Yuan and Kudo glanced at each other, tacitly, and combined the things in their hands together, and found that the fragments could fit perfectly to the back of the ancient mirror!

"This is a complete ancient mirror!"

Kudo Shinichi said in surprise, and immediately went to the book that recorded the relevant symbols that he had read before, found it, and began to interpret it against the symbols on the ancient mirror.

At this time, Gao Yuan saw that in the original drawer, under the ancient mirror, there was a stack of paper handwritten reports, and on the cover was written "About the Similarity between the Ruins of Fobina and the Fifteen Nights Village". So, Gao Yuan took it out and began to flip through it.

Soon, Kudo finished deciphering the information on the ancient mirror, and Gao Yuan, who was still reading the report, saw this and asked.

"What did you find over there?"

"The information is incomplete because there is still a piece missing. The only words that can be interpreted are: man, betrayal, big bird, revenge, these keywords. Mr. Wise, where are you? ”

Kudo said.

"Nothing particularly useful."

Gao Yuan looked at the content written on the report and said helplessly, "There is nothing particularly useful." Most of them are interpretations of the surviving texts in the remains of the shrine, and they are still incomplete. ”

As he spoke, Gao Yuan had already flipped the report to the end, but on the last two pages of the report, he saw two unexpected things - one was the underground water road map of Fifteen Nights Village, and the other was a map of Fifteen Nights Village.

Looking at these two drawings using the same proportion, Gao Yuan had a flash of inspiration, stacked them, and put them under the light, and then found that the location of the divine perch in the village overlapped with the nodes of the underground waterway!

"So that's what happened!"

Gao Yuan suddenly exclaimed, "It can be like this!" ”

"What did you find, Mr. Wise?"

Kudo Shinichi asked, and Takato handed the two drawings to Kudo.

"Murder methods! I've found this last piece of the puzzle! ”

Gao Yuan said.

After Kudo looked at the picture carefully, he immediately understood, and blurted out: "Air pressure!" ”

"That's right, the murderer skillfully used the underground waterway, through the principle of Bernoulli's equation, to lift the manhole cover made of round stone that the deceased stepped on, and pushed the person onto the divine perch!"

Gao Yuan said.

"However, if the lifted manhole cover is deviated and cannot fall back to the original point, this technique will be seen through on the spot!"

"So the murderer wants to install a brushless motor on the manhole cover! The principle of conservation of angular momentum is used to keep the attitude of the manhole cover lifted into the air stable! It's like a gyroscope used in an aircraft! ”

Kudo asked a question, and Takato immediately answered, "And under the manhole cover on the other side of the waterfall, I found a brushless motor that the murderer didn't have time to dismantle!" However, why did the murderer fail to attack Kotomi Wakura? ”

Kudo thought for a while, and then thought that last night, when he and Xiaolan ran to the entrance of the village, Xiaolan tripped over something while passing by the divine perch in front of the waterfall!

"I see! It's Xiaolan! When Xiaolan passed by there last night, she tripped over the manhole cover, which caused the manhole cover to deflect a bit, so that when she attacked Miss Kotomi, the pressure was insufficient! ”

"I see."

Hearing Kudo say this, Takato was a little surprised, "However, if all the cases are committed by the same person, who the murderer is already coming out!" ”

"Yes, that's right. This technique must see the target step on the manhole cover, and the first time in the shrine, the people present at the time, except for the deceased, me, Xiaolan, Yuanzi, and the concubine lawyer, there were only three people! ”

Kudo Shinichi said.
