Ke Xue: I picked up a bottle of sherry at the beginning.

"Oh...how about we go to Shubunkan High School and check again?" Miwako said with a wry smile.

"I've been coming here to offer paper cranes since about half a year ago."

The abbot was a white-haired old man. When he was found, he heard the purpose of the two people's visit and explained, "I have counted, and there are always exactly one hundred each time, and they are placed together with an envelope containing one thousand yuan."

"Are the one hundred paper cranes the same color every time?" asked Miwako.

"It started with yellow, then green and blue, and it's different every month."

“Have you ever seen anyone offering sacrifices?”

"No," the abbot shook his head, "He always appears when there are few people around..."

After asking the question, Miwako looked serious.

"Mr. Aoyagi did tell people that visiting other shrines was just a side trip... It seems this is where he really wants to go. I'll look for it. He might have bought the Japanese paper for the origami crane nearby."

"I'll go ask other people." Quan Yi stayed in the shrine, looking at the people coming and going to worship.

If Aoyagi Takeaki went to Suitengu Shrine to pray for a safe delivery, it would be too strange. No one in the Aoyagi family was pregnant, and there was no need to go to such great lengths. She had started visiting the shrine half a year ago.

Rather than praying for a safe birth, it's better to say...

Quan Yi walked to the place where prayer items were sold next to the shrine and his eyes fell on the price list hanging there.

"Water troubles...is there a water trouble prayer here?"

"Of course," the witch smiled, "and many people pray for their children to be spared from flood disasters."

"Sure enough, my feeling was right. The swimming club, the water disaster... So that's why Mr. Aoyagi started coming to Nihonbashi six months ago..."

Quan Yi glanced at the prayer objects, took out a photo of Aoyagi Takeaki and asked, "Have you seen this person? I heard from the abbot that he seems to come here when there are fewer people."

The witch took the photo and shook her head, "I'm not sure...Excuse me, are you a police officer?"

"Yes..." Quan Yi put away the photo of Qing Liu Wuming and handed over the business card he was carrying: "I am Bai Quan Yi. If you think of anything, please contact me..."

The miko put away her business card and continued, "Come to think of it, a few days ago, someone named Yashima Fuyuki came here and left his wishing card behind..."

"Yashima Fuyuki?" Izumi's eyes lit up and he took out a photo of Yashima. "Is this the guy?"

"Hmm," the miko nodded, looking at Yashima's photo in confusion, "Could he really be the person they say he is on TV? But is he really the murderer? He doesn't look like that kind of person. He spent all his 500 yuan on a wishing card and made a wish very seriously..."

"Where's the wishing card?"

"We helped keep it. He didn't seem to know that you can take the wishing plaque home, so he just kept it hanging on the tree next to him..."

Not long after, Shiraizumi Masu reunited with Miwako. He had a wishing card with words written on it in his hand, and the signature was indeed Fuyuki Yashima.

"For the sake of my unborn child, I pray that I can find a job quickly..."

"It was exactly the day before the incident," Izumi murmured. "I heard from Miss Nakahara that Yashima returned home very late that day because he had no money to take the train..."

Miwako looked at the wishing card, took a deep breath, and handed Izumi a bag of colored washi paper. "Mr. Aoyagi is indeed making paper cranes with this kind of washi paper. Ten colors, starting with yellow in the middle, yellow, green, aquamarine, cyan, purple, and finally white. One hundred of each. After praying and taking photos at other shrines, place them at Suitengu Shrine along with a thousand-yuan letter..."

"Water disaster," Izumi continued, "Miwako, besides praying for a safe birth at Suiten Shrine, you can also pray for relief from water disasters... It's definitely related to Aoyagi Yuto..."

Miwako and Izumi walked side by side and nodded in affirmation, "Officer Bai, your intuition is correct. It seems that another investigation is necessary."

"Yes." A smile appeared on Quan Yi's face. Although the case was still a bit complicated, the feeling of being close to the truth of the incident was particularly strong.

Because Aoyagi Yuto and that teacher seemed to be taboo about something and didn't even talk about the swimming club accident...

In the evening, Miwako went to Shubunkan Junior High School to investigate, while Izumi visited the Aoyagi family again.

After paying tribute to Aoyagi Takeaki, before I could question the Aoyagi family, I received a call from Officer Shiratori.

"Have you found the place for Yashima's interview?"

"Yes," Officer Shiratori contacted, "It's a furniture store in Kyobashi. As expected, he applied after seeing the notice posted outside the store. The boss wasn't there on the first day, so the job was rescheduled to six o'clock the next evening. However, at the time, they were only looking for part-time students running events, but Yashima wanted to apply for a furniture maker, so the boss recommended that he apply at another store in Edogashi..."

"Edo Bridge," Izumi thought of the Edo Bridge where the crime took place and continued to ask, "And then, did they accept him?"

"No, Mr. Yashima only did carpentry as a hobby. He couldn't meet the store manager's requirements, so he left around seven in the evening."

"Seven o'clock in the evening..." Quan Yi hung up the phone silently.

Mr. Aoyagi entered the coffee shop around 7:30, so the distance and time were quite consistent.

"What else is there to investigate?" Aoyagi Yuto observed coldly. "Didn't the TV already make it clear?"

Izumi turned around and looked at the stern-faced Aoyagi Yuto. "Don't you want to know why your father went to Nihonbashi? Are you just going to accept the case being closed without knowing the reason?"

"What's there to accept or not?!" Aoyagi Yuto said angrily, "Isn't it just that my father, who deliberately concealed a work-related injury, was killed by a resentful man? He went to the famous Nihonbashi Bridge for no reason, so he caused an uproar in the media and caused so much trouble...

"It's not just the 5.5 school, now even the neighbors are talking about it all the time, and there are reporters surrounding the door every day!"

Izumi looked at Aoyagi calmly and said, "On the night of the incident, Mr. Aoyagi dragged his severely injured body and struggled for over ten minutes to reach Nihonbashi Bridge. He didn't ask for help from anyone, not even the police officer nearby. The patrolman said he exhausted all his strength to reach the Kirin statue before collapsing...

"I don't know why Mr. Aoyagi went to such lengths, but for six months, you've been praying at Suitengu Shrine, folding paper cranes... You should know something, right?"

"Paper crane?" Aoyagi Yuto suddenly stopped listening to Quan Yi. He turned around and left the living room, ran upstairs, and slammed the bedroom door.

The living room fell silent, with only Quan Yi and Mrs. Qingliu, who looked haggard, sitting beside him.

Mrs. Qingliu hesitated and said, "Is concealing a work-related injury such a heinous thing? Even if you get killed, it's what you deserve."

Quan Yi came to his senses.

"Is it because of the TV show? Hiding a work-related injury is a crime, and some people might harbor resentment, but if someone is killed for something like that... I don't think it should be. Human life is not something you can take lightly."

New evidence

Shiraizumi Masushi and Miwako meet in a park in Tokyo.

"I've already checked at Shubunkan Junior High," Miwako said as they walked together in the park. "Three years ago, a counselor worked late and found a student named Yoshinaga Tomoyuki drowned when he left... This is his version of events."

"Where is Yoshinaga?" Izumi asked.

"I moved to Nagano," Miwako replied.

"Miwako," Izumi stopped and said, "I'm going to go to the crime scene. I want to go back to the starting point and sort out the clues again. Do you want to come with me?"

"Um……"

At night, near the Edo Bridge Tunnel.

The lights quietly illuminated the road among the green plants. Few pedestrians passed by, and homeless people were lying on the benches by the roadside.

Izumi and Miwako walked along the way, confirmed the Kirin statue in Nihonbashi, the crime scene in Edo Bridge, and finally arrived at the place where Fuyuki Yashima was found by the patrolman.

After actually walking through it, I felt a much richer understanding than looking at a map. It was as if I had witnessed the crime with my own eyes, and saw how Qing Liu Wuming staggered across hundreds of meters despite his injuries.

"There were few people on this stretch of road that day, but there were still plenty of opportunities to seek help. There was a police station right in the middle..."

As Miwako walked, she explained what happened on the day of the crime. Suddenly, she noticed Kaori Nakahara walking silently towards her, and she quickly pulled Izumi Masu.

"Miss Zhongyuan?"

"Officer Bai, Mr. Detective..." Nakahara Kaori was startled, "Why are you here?"

"Come back to investigate again," Miwako walked to a bush, "Yashima made his last phone call... right here, and then he was discovered by the patrol and ran away..."

Kaori Nakahara pursed her lips and looked towards the green plants. She could clearly see footprints and seemed to feel the panic that Yashima was feeling at that time.

"I still can't believe that Fuyuki would do something like murder... Officer Bai, Mr. Detective, there's no way Fuyuki would kill someone!"

Miwako looked at the anxious Nakahara Kaori, paused and said, "I know, Inspector Bai and I are working hard."

"Really?" Nakahara Kaori turned to Izumi with gratitude, "Officer Bai..."

"Nothing, this is my job." Izumi held a map of the Nihonbashi area in his hand, marking the entire route of the case. Thinking of the Yashima wishing plaque on his body, he asked Nakahara Kaori, "Ms. Nakahara, did you really not tell Mr. Yashima about your pregnancy?"

"Yeah," Nakahara Kaori nodded slightly, "Because I was really scared... when he was unemployed and broke, if he found out I was pregnant, he might abandon me... That's why I said such extreme words, hoping he could find a job..."

Quan Yi took out a wishing card and handed it to Kaori Nakahara.

"Mr. Yashima should know... Actually, the reason I was looking for socks without holes that day was because I had a job interview at a furniture store..."

Nakahara Kaori gently took the wishing card, her fingers trembling slightly: "Fuyuki..."

"The day before the incident, he made a special trip to Suitengu Shrine," Quanyi continued, "and spent his own money to buy this. Since it was hung on the tree, the shrine is keeping it for safekeeping..."

Nakahara Kaori choked up and hugged the wishing card tightly: "I don't know anything..."

Before they knew it, they were on Nihonbashi Bridge again and stopped in front of the Kirin statue in the middle, which was exactly opposite the place where Aoyagi Takeaki died.

"Why did Miss Nakahara come here? It's probably not convenient for you to go out in your current health, right?" Quan Yi asked Kaori Nakahara who was immersed in memories.

Nakahara Kaori came back to her senses, wiped her eyes, looked at the Kirin statue and said, "Fuyuki and I first came to Tokyo by hitchhiking and got off here... The driver said this was the starting point of Tokyo, and we were very happy at the time..."

"When was that?" Quan Yi's expression changed slightly.

"Well, it seems to be around this time three years ago... I remember it at first because it was our anniversary, but we didn't celebrate, and then Fuyuki and I gradually forgot about it..."

"No impression at all?"

"There should be something else written in the diary..." Nakahara Kaori asked doubtfully, "Is there something wrong with this?"

"Nothing," Izumi pondered, "I just thought Yashima might still remember, so I came here... Miss Nakahara, could you please check it out?"

"Eh?"

"I should be able to find out the time just by checking the diary, right?"

"I understand." Kaori Nakahara nodded in confusion.

After separating from Nakahara Kaori, Miwako spoke first, "Inspector Shiro, I've just studied Mr. Aoyagi's route from the cafe to the subway station, as well as Yashima's possible movements...

Shiraizumi replied, "Mr. Aoyagi would have passed through this area on his way home. After Yashima's failed interview, he was likely passing through here as well. What's strange is that there were nearly two hours between the time he left the furniture store at seven o'clock and the time the crime occurred. If he hadn't gone to the cafe with Mr. Aoyagi, he should have left the area long ago..."

"I think so too," Miwako agreed. "The key is what Yashima was doing in the middle of this."

Quan Yi recalled the footage of Aoyagi Takeaki's death that he had captured during the initial investigation, and glanced around Nihonbashi Bridge. "I remember there's surveillance here, right?"

That night, Shiraizumi Masu and Miwako hardly slept, and only stayed in the Metropolitan Police Department's monitoring room for a while.

The next morning, Izumi learned that Aoyagi Yuto's sister Haruka almost committed suicide by cutting her wrists, and hurried to Aoyagi's house with Miwako.

Because Mrs. Qingliu discovered it in time, the girl was not seriously injured, but her mental state was very bad. After medical bandage, she temporarily fell asleep in the bedroom.

"My classmates at school said some unpleasant things, and people online are saying my husband deserved to be killed..." Mrs. Qingliu said tiredly, "I can only take a leave of absence for the time being..."

"You're such an idiot! If you commit suicide, wouldn't that be the same as admitting that your dad did something wrong?" Aoyagi Yuto stayed by his sister's bed for a while, and turned and left the room without paying any attention to Mrs. Aoyagi and Quan Yi who pushed the door open.

Although Qingliu was still unwilling to communicate with the police, his attitude towards his father had completely changed.

"Yesterday he was saying his dad deserved it..." Quan Yi sighed, "Did he find out something? Did he meet with anyone?"

"Well," Mrs. Qingliu said in embarrassment, "I'm not quite sure..."

"Dong dong!"

Quan Yi walked to the outside of Aoyagi Yuto's bedroom and knocked on the door: "Yuto, can I ask a few questions?"

Hearing no response from the room, Izumi continued, "Three years ago, there was a swimming competition at Shubunkan Junior High School, right? Did you participate in that competition? And Yoshinaga Tomoyuki, the student who nearly drowned... you should know him, right?"

In the bedroom, Aoyagi Youren's expression changed slightly, and he looked at the door with his fingers clenched.

"So what if you know?"

"Six months ago, your father went to Shuitian Temple to pay homage. They pray not only for a safe birth, but also for protection from flood disasters... What exactly happened to the accident three years ago? It might be related to your father's incident. Can you tell us?"

"I can't answer your question," Aoyagi Yuto tightened his grip on his fingers, opened the door, looked directly at Quan Yi and the others, and said, "If it's all right, could you please leave me alone for a while?"

"Ding ding ding!" The cell phone in Quan Yi's arms vibrated. He looked at Qing Liu You Ren and walked aside to answer the call.

"Officer Shiro," Shiratori's voice came from the other end of the line, "The Nihonbashi surveillance camera did capture Mr. Yashima. It's confirmed that the time was around 7:40 p.m. on the evening of the incident. The victim and others were in the cafe at the time..."

"I understand." Quan Yi felt relieved. No matter what, with the new evidence, the procuratorate could not easily close the case according to the original plan. At least they had to find out who the other person was who entered the cafe with the victim.

However, Aoyagi Yuto refused to say anything, which was a bit troublesome...

After leaving Qingliu's house, Quan Yi couldn't help but shook his head.

"It's clearly related to the truth about his father's case... What is he hiding?"

"From the looks of it, it's not just his own problem. I'd better wait until we get to Nagano before we talk about it," Miwako said, looking back at the Aoyagi residence. "Perhaps after meeting Yoshinaga, we'll know everything."

……

In Nagano Prefecture, Izumi took a long detour to find Yoshinaga's house, and in the process he received a call from his co-worker Yokota at Yashima.

"Mr. Qingliu seems to be unaware of the safety hazards of gold, stone and metal. Every time he inspects the safety devices, he opens 86
