Chapter 21 Section 8

"No matter what you say, I believe this time it is haunted. It is because the ghost of Kanzaki Toshiyuki is buried below that this phenomenon will appear." Kusanagi put the cup to his mouth and said.The cup contained the representative drink of Research Room 13 - instant coffee with a light taste. "What you think is your freedom, and I don't mean to force you, but I personally think it is a resonance phenomenon." Tang Chuan's voice was calm, the more excited the other party was, the colder he was, this was his Habits formed in youth. After hearing Sao Ling's statement, Tang Chuan first went to the city government to investigate the underground structure near Gao Ye's house, and found that there was an old sewer maintenance channel directly below Gao Ye's house, so he concluded that the cause of Sao Ling was it's here.

"Every object has its own fixed vibration frequency. If the vibration frequency of the external force applied to the object is the same, the object will vibrate violently. This is the resonance phenomenon. I think, for some reason, the sewer maintenance channel When the surrounding environment changes, a resonance phenomenon occurs.” Yukawa speculates that the reason is that the ground has been subjected to some kind of force, for example, a hole has been dug. Once he thought of digging a hole in the ground, the other party's intentions became clear.Kusanagi couldn't help feeling an ominous premonition, which was finally confirmed.

Through investigation, Tang Chuan learned that there is a parts processing factory near Takano's house, and the sewer pipe of this factory is connected with the sewer maintenance channel of Takano's house.Every night at 8 o'clock, the factory discharges treated hot water, which forms an airflow in the sewer pipes and resonates with the sewer maintenance channel directly below Takano's house. On the day the body was found, Kusanagi asked the factory to release water at 3 o'clock in the afternoon. "Okay, I should go." Kusanagi put down the cup and stood up. "Are you going to see her now?" Tang Chuan asked.

"Yes," Kusanagi replied, "I've been busy recently, so I haven't explained it to her in detail yet." Although reluctant, he knew that this kind of errand could only be done by him. "Don't want to stay for a while and hear about Takano's legacy?" When Toshiyuki Kanzaki was buried, he was wearing a suit, and his belongings were left in his pockets intact.However, he was short of cash and credit cards in his wallet, and the criminals planned to use his credit cards to make a lot of purchases. They overlooked the most important thing: a card tucked into their driver's license.

That was the card key of the bank customer's personal safe. It was not Kanzaki's own, but Takano handled it at the bank. The agent's name was registered with Kanzaki Toshiyuki. According to the police investigation, in addition to the passbook, there were bonds, precious metals, real estate certificates, etc. in the safe, and there was also a letter. This is a will, clearly stating that all property will be left to Kanzaki. "Until now, do you still think it's a ghost?" Tang Chuan asked. Kusanagi, who was walking towards the door, turned around: "Of course, can't it?"

"No." The physicist shook his head. "Then I'm leaving." Kusanagi opened the door. "Kusanagi." "What's wrong?" Tang Chuan hesitated for a while, then said, "Be sure to explain." Kusanagi raised one hand and left the room.
