"Yamaguchi Police Department, I have already sent my subordinate Yuichi Aizawa to visit him, we need your help!" Early the next morning, just after Aizawa set off, Lin Shuichi immediately reported the information found to the Yamaguchi Police Department, who was originally in charge of this case. After all, Futu Village is under the jurisdiction of the Yamanashi Prefectural Police Headquarters. If the people from the Metropolitan Police Department don't even say hello, they can't say anything about it, and in Yamanashi Prefecture, the only thing Lin Shuichi can rely on is the retired police department of Chiaki Yamaguchi.

"Could it be that you've found a new clue?" asked Chiaki Yamaguchi, surprised.

"At present, it is only speculation that the Yamaguchi Police Department, Kanako and I visited Ayu's old family, Shimojo Village, Ono County. From the mouth of Ayu's former teacher, Ms. Akiyama, we know a strange thing. Just ten years ago, a few months after Ayu's murder, Ayu's female friend at Shimojo School, Miyu, also died of illness, and Miyu's ashes were sent back to his hometown by the man who claimed to be Miyu's boyfriend after the Yamanashi Prefectural Police ended their search of Shimojo Village...... "Lin Shuichi introduced his new discovery in Shimojo Village to the Yamaguchi Police Department in detail, and he now hopes that the Yamaguchi Police Department can help him investigate the man who sent Miyu's ashes back to his hometown.

"What's that guy's name?" asked the Yamaguchi Police Department impatiently.

"Principal Akiyama only remembers his surname Miyamoto and claims to be an office worker in Tokyo!" replied in embarrassment.

"How can this be good with only that little information?" said the Yamaguchi Police Department, disappointed.

"Police, what I want to ask you to help with is not to investigate Miyamoto's whereabouts, we should be able to find out where Miyu's body sparked now, if Miyu's ashes recipient is this Miyamoto, maybe we can get more information about Miyamoto from the ashes registration agency, as well as the death registration authority......," Lin Shuichi said again.

"Okay, I understand what you mean, when your subordinate arrives, I will arrange everything before he arrives!" Hearing this, the Yamaguchi Police Department suddenly had confidence again. He couldn't wait to get up from his chair, and after discussing the next search plan with Lin Xiuyi, the Yamaguchi Police Department hung up the phone and ran to the porch to change his shoes.

"You're going out, didn't you promise to accompany me to the mall for a while?" the wife of the Yamaguchi Police Department saw that he was in a hurry, and hurried out to inquire.

"I have something to do now, let's go to the mall later! By the way, I won't be back for dinner for a while......" As soon as he finished speaking, the Yamaguchi police department ran out.

……

Two hours later.

"Ding-dong......!"

The doorbell of Saito's house rang, and Saito, who was writing the first draft of his new book, put aside his pen in annoyance, got up and went downstairs to open the door.

"Hello, you're Professor Saito!"

Saito was very puzzled when he saw a group of people wearing suits standing at the door, so he subconsciously asked, "Who are you!"

"I'm Kenji Yamada from the Search Division 1 of the Yamanashi Prefectural Police Headquarters! Now we need to verify something with you!" After the other party finished speaking, he handed him a police search document, and then a group of criminal police officers with armbands on the search section 1 rushed into Saito's villa.

"What the hell are you going to do?" Professor Saito immediately became excited when he saw that the other party was not good.

"Please cooperate!" Kenji Yamada warned Saito.

Saito was worried that the police would turn his home into a mess, so he quickly followed the police to his study on the second floor.

"This is the little judgment that claims to be able to uncover the mystery of Shingen's buried gold!" Kenji Yamada asked Professor Saito.

Saito was unhappy that the gang had stormed his home, but he was a university professor and knew he had an obligation to cooperate with the police. So Saito nodded angrily, he didn't want to pay attention to these policemen at all.

"Call the people from the forensic class to come up!" Kenji Yamada gave an order, and in less than half a minute, a man wearing a blue uniform and an armband of the forensic class came to the study with a toolbox, and after he put on his gloves, he directly opened the layer of plexiglass that was covered by Jin Xiaoju.

"What are you doing, this is a very precious cultural relic, you ......"

When Professor Saito saw that someone dared to touch his beloved Jin Xiaoju, he immediately became furious, but unfortunately the police standing next to him easily subdued his excesses.

"Professor Saito, please cooperate, otherwise we're welcome! Oguri-kun, let's get started!"

The technician known as Oguri-kun's forensic class nodded at Yamada, then took out a bottle of reagent from the toolbox and carefully sprayed it on the surface of the small gold judgment. After the spraying work was completed, Oguri-kun nodded to the person who searched the first class, and the police officers present closed the curtains in the room in understanding.

In the dark study, the piece of gold in Oguri-kun's hand emitted a faint blue fluorescence, like a ghost fire, although the light was faint, but it was enough to explain the problem. After about 30 seconds, the fluorescence eventually fades away. The police reopened the curtains.

"Professor Saito, we now ask you to cooperate with our investigation, please come with us!" Kenji Yamada said coldly to Saito.

"You ...... What are you doing, I don't know anything, you must have made a mistake somewhere......" Saito said loudly in panic. Unfortunately, it doesn't help anymore, and the little test just now is enough to explain the problem.

"May I ask if luminol won't affect DNA testing, right?" Kenji Yamada waited until Saito was taken away, and quietly asked his colleague Oguri-kun in the forensic class.

"Please rest assured that it will not affect our DNA identification results!" said the other party without hesitation.

Yamada's subordinates escorted Professor Saito into the police car, and the precious small judgment was also taken away by Oguri-kun. Yamada finished his business and didn't hurry downstairs.

"Senior Yamaguchi, everything is done, and there is really a problem with that small judgment. After Yamada saw Chiaki Yamaguchi, he said respectfully.

"Well done Yamada, now I can finally continue to search the secret room case of Futu Village ten years ago! If I can solve the case this time, I will have no regrets in my police career! By the way, let me introduce you, this is Aizawa Crime, a subordinate of Lin Xiuyi's police department!"

Yamaguchi introduced Aizawa to the Yamada Police Department, and the Yamada Police Department shook hands cordially, and then discussed the next plan of action. At this moment, Yamada's mobile phone suddenly rang.

"Police Department, we found Miyu's death record at Kofu Central Hospital, and the name in the family column is Miyamoto Kuranosuke, but all the information called Miyamoto is fake......"
