"According to the medical records of Fuku-no-kami Hirahara's psychiatrist, Fuku-no-kami Hirahara previously suffered from a mild case of multiple personality disorder.

The stimulation of childhood memories may be the root cause.

Family migraines and life stress further amplified the effects of the disorder."

The doctor sighed and said:

"In general, the personalities within a patient with multiple personality disorder are independent and autonomous.

They exist as complete selves. Only one main personality can control the body at any given time.

Usually, after being subjected to mental stimulation, they will suddenly transform into a completely different identity, completely forgetting their past identity, which is to switch to another personality.

After switching back to the original main personality, the main personality knows nothing about what happened during the second personality."

"Fuku-no-kami Hirahara's psychological condition is very special and complex.

Since childhood, he has been constantly generating secondary personalities,

using them to help him avoid childhood memories and release stress.

These secondary personalities disappear very quickly, often before they have time to grow and develop into independent personalities,

and are then destroyed by Fuku-no-kami Hirahara's own subconscious,

becoming a pile of fragmented memories filled with fantasy and inconsistent with reality.

Therefore, Fuku-no-kami Hirahara cannot recall many things from his childhood.

That memory is blurry and chaotic for him."

Li Ang raised an eyebrow. "The drug you injected into my arm earlier was used to excavate those blurred memories, right?"

The doctor nodded. "After capturing Fuku-no-kami Hirahara, the police found him disoriented and in a daze, unable to be interrogated at all.

We speculated that the person who committed the massacre was either Fuku-no-kami Hirahara himself, or one of the personalities within him.

Saving lives is like fighting a fire, so we could only follow the advice of his psychiatrist and inject an experimental drug from a pharmaceutical company into Fuku-no-kami Hirahara.

This was both to awaken a personality that was clear enough to complete the interrogation,

and to excavate Fuku-no-kami Hirahara's childhood memories, find the logic behind his criminal behavior, and rescue the hidden Weimen Zi Yuan."

Li Ang thought for a moment, then spread his hands and said, "Then why not just ask Fuku-no-kami Hirahara's psychiatrist to come over? It should be much more effective if he came."

"This..."

The doctor's expression changed slightly. After exchanging a glance with the police chief, he replied helplessly, "Fuku-no-kami Hirahara's psychiatrist is named Weimen Youren, and he works at the Kayama City Sanatorium.

He is also the husband of Weimen Xingzi, Fuku-no-kami Hirahara's daughter.

At the time of the incident, Fuku-no-kami Hirahara had asked Weimen Xingzi to bring her husband and daughter to visit,

but Weimen Youren had already gone out, so Weimen Xingzi only brought her daughter to visit her father."

"...Okay."

Li Ang sighed. He felt that Weimen Youren had just had his wife killed by his father-in-law, so it was a bit inappropriate to ask him to help with the interrogation now.

"Okay, I'm willing to cooperate with you.

Although I'm just a newly born personality, I'm still two sides of the same coin as Fuku-no-kami Hirahara.

His granddaughter is my granddaughter, so naturally, I have to save her."

"Phew, that would be great."

The psychiatrist breathed a sigh of relief and continued, "So, Kawa-san, what did you see in your memories earlier?"

"Some scenes comparable to urban legends."

Li Ang briefly described the headless mochi man, the strange singing troupe, and the two urban legends from the test of courage. "These should be Fuku-no-kami Hirahara's childhood memories, right?

What are their prototypes?"

The doctor replied, "Fuku-no-kami Yamato was a well-known folklorist. He was very prestigious abroad and revered by his hometown elders and Fuku-no-kami Hirahara.

In March of Showa 52, he returned to his hometown and began to study the local legends. In the process, he seemed to have suffered from familial migraines and developed symptoms of schizophrenia, publicly cursing the villagers to go to hell.

Finally, on the evening of March 26th, he committed suicide by seppuku in the old house of Fuku-no-kami Hirahara's grandfather.

Two months later, Fuku-no-kami Hirahara's younger sister, then eight-year-old Fuku-no-kami Yui, mysteriously disappeared in the countryside. Local police and villagers worked together to search extensively for more than ten days, but still could not find her.

The villagers believed that Fuku-no-kami Yui had encountered 'Kamikakushi', that is, she was hidden by gods and monsters.

Fuku-no-kami Hirahara's cousin, Fuku-no-kami Hideri, couldn't stand the successive mental blows, went insane, and was sent to the Kayama City Sanatorium—the place where Weimen Youren used to work—for treatment after spending some time in the countryside."

"Hmm... In that case, the headless mochi man in the first memory should be the insane Fuku-no-kami Hideri.

And the little girl in a white kimono, surrounded by the singing troupe, is the mysteriously missing Fuku-no-kami Yui.

Fuku-no-kami Hirahara couldn't accept these things, so he twisted his memories and painted them with extremely strong magical horror colors."

Li Ang muttered, "The test of courage that took place in high school should have actually happened in the real world.

At that time, Fuku-no-kami Hirahara was approaching adulthood, and he had sorted through his past memories many times.

Although he didn't want to recall them, his brain still provided a reasonable explanation.

His sister disappeared because he opened the [Box Containing Body Parts],

and Hideri went crazy because he saw the distorted white human figure in the rice field.

This explanation allows Fuku-no-kami Hirahara to go from being a personal experiencer of the events,

to a narrator, an observer,

thereby releasing mental stress.

Of course, this explanation is too far-fetched.

As a high school student, he naturally couldn't believe the increasingly certain memory and could only treat it as an urban legend."

Li Ang raised his head and looked at the psychiatrist. "I want to see Fuku-no-kami Hirahara's diary. The police must have gotten their hands on it by now. Show it to me."

The police chief glanced at the doctor, and after receiving the latter's nod, took out the kraft paper diary from the thick file folder and handed it to Li Ang.

Li Ang took the diary and inspected it to make sure it was the original one, then flipped to the page where Xinghe Chou had stopped earlier and continued reading.

In fact, when Xinghe Chou was about to be transported into the first memory, Li Ang had already seen a lot of content by quickly flipping through the pages.

Asking the psychiatrist relevant questions was just to test whether the other party was lying.

"86.8.1, Received the admission notice from the university in Tokyo. Dad was very happy, drank a lot of wine, and talked about many things. In the end, he seemed to be drunk and said that he hoped that I could study in Tokyo and live there for the rest of my life, and not be as stupid as Uncle, who went back to the village again. I decided to start keeping a diary again. From eighteen to eighty. The pages of the diary might not be enough, so I won't occupy one page a day."

Li Ang quickly read the diary, asked the police chief to give him a piece of paper and a pen, and recorded the more important times in the diary.
