"It's good for you to understand, the teacher has not asked about the world for many years, although the people in the club give the teacher some thin noodles, but the teacher is a police officer after all, and it is really inconvenient to contact you in some public places."

Sachiko Asami tilted her head to the side, "The teacher said that he didn't plan to take care of Sachiko's business?" ”

"How come, your father and I are old acquaintances, this time he suffered a tragic accident, the teacher must take care of it, otherwise he wouldn't invite Optics Valley Tengyi to come."

As he spoke, Professor Matsuno glanced at Kenichi Tani.

"Yes! On the way here, I was discussing with my teacher about Sachiko's father. ”

"Oh?" Ji Han looked up at Optics Valley Tengyi, "Senior brother, has you already analyzed something?" ”

"Mr. Kawano has been in charge of the Asahi Society for many years, and there are indeed many enemies in Nara, but the one who chooses to attack Mr. Kawano at this juncture must be related to Takamatsuzuka."

"Takamatsuzuka?" Ji Han shook his head, "Takamatsuzuka's affairs have always been taken over by the teacher, and even if the prophecy is imminent, they have no reason to attack Mr. Kawano." ”

Sachiko Asami glanced in my direction, "It's not a good time to discuss this today." ”

Ji Han knew that Sachiko Asami felt that I had nothing to do with this case, and it was not appropriate for me to hear this. "Don't worry, Miss Sachiko, Lin Xuan has been investigating the murder of the Jade Toad Palace, and I think Miss Sachiko must have heard of the name Su Yichen."

"Su Yichen?" Sachiko Asami touched her face with her hand, "I heard, he came to the club to find my father half a month ago. ”

I looked at Ji Han in confusion, "Could it be that Mr. Kawano's murder is related to the Jade Toad Palace?" ”

"I heard you've been investigating a case about the resurrection of the ancients?" Professor Matsuno said straight to the point.

"Yes," Ji Han nodded, "But the authenticity of the words is still being investigated, and I don't really approve of the resurrection of the dead." ”

"Those two guys from Takamatsuzuka are also your friends, right?" Optics Valley Tengyi asked.

"Takamatsuzuka?" I glanced at Ji Han in surprise.

"It's Li Mubai and Du Feng." Ji Han whispered.

"Oh!" I smiled and nodded, "That's our friend, we've been investigating the matter of Bai Yu Toad, I don't know if the professor has never heard of the name Bai Yu Toad." ”

"Of course, Bai Yuchan, the fifth ancestor of the Southern Sect of Chinese Taoism, traveled to Penglai in his early years, and according to legend, the place he traveled to was Nara, and Takamatsuzuka seems to have something to do with him."

"What the hell is Takamatsuzuka?" I asked with a frown.

"Didn't Ji Han tell you?" Guanggu Teng said expressionlessly.

"We don't know the specifics yet, we only know that there is a suspicious coffin in Gao Song's mound, and according to the clues we found, it should be related to the white jade toad."

Sachiko Asami lowered her head, and what Ji Han said seemed to deviate from what she knew, "My father told me that the Asami family has guarded Takamatsuzuka for generations, and the things inside must not be touched. ”

Professor Matsuno nodded, "I've been studying Takamatsuzuka for many years, and the secret inside it seems to be related to the demon clan, so I think the person who killed Mr. Kawano must have noticed something." ”

"In recent years, there have been a lot of disturbances in Nara, and I have always thought Takamatsuzuka was suspicious, but my uncle told me that people with Japanese imperial blood should not touch Takamatsuzuka, and I tried to get closer, and something terrible happened." Optics Valley Tengyi looked palpitating.

"It seems that we have to start with the murder case."

Professor Matsuno nodded, "Kato Ashio is very dishonest, I heard that he let people spread the guise of supernatural killing. ”

"So there's really anything supernatural going on in that building?" Ji Han asked Sachiko Asami.

"I heard from the migrant workers who worked inside that something unusual was happening, but," Sachiko Asami paused, "it seems that the sushi restaurant is also abnormal." ”

"You mean the one across the street?"

"Well," Sachiko Asami nodded, "I've been there a few times, and their proprietress is a little unusual. ”

"Is there one?" Ji Han held his face with his hands, as if he was thinking about the situation when we went to the Asahi sushi restaurant in the morning.

"A girl's intuition."

"Let's start with that sushi restaurant." Professor Matsuno said.

Sachiko Asami and Tengi Kouya both said that there was no problem, Ji Han also nodded, I deliberately looked up at him, that day Ji Han took me back to the sushi restaurant to pick up something, obviously Professor Matsuno did not know about this matter.

Soon the pre-dinner conversation ended, and Professor Matsuno motioned for us to enjoy the Japanese set meal he had prepared for us.

"Eating sashimi is a very particular thing in Japan." Sachiko Shiokai said.

Ji Han nodded, "Japanese cuisine is exquisite, there are many items, and each product is "less but fine". So, in Japan, you have to finish eating one dish, remove the empty plate, and then go up and down the next dish. ”

"So we have to finish this horse meat sashimi before we can serve the next dish?" I asked with a bitter face.

"Of course," said Optics Valley Tengyi with a smile, "Mr. Lin must hurry up and eat, otherwise we won't have time to eat the next dish."

I smiled wryly and nodded, and Professor Matsuno told me that when Japanese people eat together, it is very taboo for two people to serve one dish at the same time, because in ancient Japan, when cleaning up the bones of dead people, two people were sandwiched together, so the act of sandwiching together seemed very unlucky in the eyes of the Japanese.

I don't really like horse sashimi, but the order in which the food is served in Japanese people is very particular. I took a closer look at the fact that in Japanese cuisine, the order of serving is usually matcha or barley tea first, and the appetizer is basically a variety of pickled side dishes, such as boiled edamame, roasted ginkgo, vegetable salad, sashimi, sushi, sake or shochu, etc.; This is followed by sea-salt charcoal-grilled fish, skewers, Japanese-style steamed egg custard, matsutake soup or miso soup, stir-fried soba noodles, fried dumplings, octopus balls, soup and rice, etc.; Finally, there will be Japanese ramen and desserts.

Of course, these dishes are prepared by Professor Matsuno, and I'm not sure if this is the order of serving in other places, but I can be sure that people who live in Japan are always very strict about their lives.

After eating the horse meat sashimi, I decided to drink a bowl of soup first, but there didn't seem to be a soup spoon in the bowl. Ji Han reminded me in a whisper that in Japan, you don't use a spoon to drink miso soup, but use chopsticks to pick up the food inside and drink it directly to the bowl. In addition, after the chopsticks are picked up, they should be placed horizontally on the side close to them, on the holder of the chopsticks, and do not stick the chopsticks in the rice, because this is the practice of sacrificing the dead in Japan, and do not point the tips of the chopsticks at the person opposite. Anyway, it was very complicated, I ate very depressed, and the whole night I felt like I was studying etiquette class.

"I think everyone has eaten about the same, right?" Professor Matsuno stood up and said.

"Does the teacher have any other arrangements?" Ji Han asked in surprise.

"I got some video footage about the murders."

As he spoke, Professor Matsuno asked the waiter to turn on the projector in the box, which is often prepared in the business box, and many people are used to talking about business issues after dinner.

The screen is on, it's a video, it's very dim, it should be shot at night.

"This is a video captured by surveillance outside Takamatsuzuka."

I looked up and looked closely, and the Takamatsuzuka that I could see on the screen was a small circular burial mound about five meters high and more than ten meters in diameter, located in a park-like place. Professor Matsuno has been researching the Takamatsutsuka Kofun, and the surveillance video he brought must have captured something unusual.

"What is this?" Ji Han and Tsutsuya Tengyi looked at me almost at the same time.

A figure appeared on the flickering screen.

"Turn the clock back to 1 minute and 30 seconds." Professor Matsuno commanded.

"This person," Sachiko Asami also looked back at me, "how can he be so similar to you?" ”

I was amazed to see that the people on the screen were indeed very similar to me, but I was pretty sure that I had never been to Takamatsuzuka.

"This person is not him." Professor Matsuno said firmly, "This is an image from 10 years ago, and Mr. Hayashi should have been just a teenager at that time. ”

"And who is this man?"

"We suspect it's Mr. Lin's father."

"My father?" I shook my head, "They went to Australia when I was very young, and my father and I don't look very similar. ”

Sachiko Asami nodded, "I'm sure of that, I investigated Kato before he handed him over to me. Lin Xuan, 26 years old, graduated from Changlin Police College, his parents moved to Australia, and he lived alone without other relatives and friends. I've seen photos of his parents, and his father is indeed not very similar to Lin Xuan. ”

Professor Matsuno's eyebrows tightened, "I have been studying the Takamatsutsuka Kofun, and on that stormy night ten years ago, Mr. Hayashi was not the only one in the surveillance. ”

The video continues to play, and Sachiko Asami, Ji Han, Tengichi Hikariya, and Professor Matsuno all appear in the video one after another.

"Did we travel back in time to ten years ago?" Optics Valley Tengyi scratched his head with his hand, this matter was a bit extraordinary.

"Chances are," Professor Matsuno nodded, "If my calculations weren't wrong, we would have been back ten years ago. I don't know how I got back. ”

"How did this surveillance video come about?" Ji Han asked.

"Ten years ago, a stranger sent it to me, and the footage behind it has been deleted. However, it can be seen that the mysterious person who sent me the video is probably one of us. ”

"We've had the unthinkable, and someone wants this thing to stop that from happening." Sachiko Asami's reasoning is not entirely unreasonable, but I can't figure out how we traveled back through it.

"Could it be related to a murder?" Ji Han guessed.

"Possibly," Kouya Teng nodded, then glanced at Sachiko Asami, "I think there are some secrets of the Takamatsuzuka Kofun that we should share." ”

Ji Han tilted his head, Sachiko Asami did not reply, and Professor Matsuno knew that they all had their own plans in their hearts.
