Lin Shuichi and the others stayed at Yamamoto's house for about an hour, and then drove to the stream outside the village to pick up Aizawa and Hanagata.

The car drove out of the village along the road, passed by Futu Temple, and after driving about two kilometers forward, it came to the stream where Aizawa was fishing.

"How's today's harvest?" said Lin Shuichi parked his car in the open space on the side of the road, stood on the bridge and greeted Aizawa and Hanagata under the bridge.

Aizawa gave Lin Xiuyi a thumbs up, and it seemed that he had good luck today. Hanagata somewhere got a metal detector and was concentrating on his treasure hunt barefoot on the riverbank.

Anyway, it's still early before lunch, so everyone just takes a break on the side of the road. The car driven by Lin Xiuyi is an MPV specially modified for travel, and the doors on both sides can be opened. Because I was going to the mountains, I brought camping chairs and tents with me at the back of the car.

Lin Xiuyi took out the chair, placed it in the back of the car, and took out a cold drink from the refrigerator in the car. Beckoning everyone to rest here for a while.

The sun was not shining in the mountains, and there was a slight mist in the valley. From time to time, there was a breeze in the woods.

Standing on the bridge and looking out, the vegetation on both sides of the stream is dense, and the birds are singing and the flowers are fragrant. Looking up, the Futu Temple looms in the mist of the valley in the distance.

Lin Xiuyi leaned on the railing next to the bridge, and his mind kept recalling the conversation with Kengo Yamamoto just now. This ten-year-old case reveals strange things everywhere. A secret room sealed by snow, and a murderer who disappeared out of thin air......

"Kanako, how much do you know about the deceased Ayu?How is she a person, and did she have any financial or emotional entanglements with people during her lifetime?" These contents are not mentioned in Kanako's information, and Lin Xiuyi naturally has no way of knowing. But judging from the motives for killing, there are nothing more than that. Because the victim is a good-looking young woman, it is likely that the murder was caused by emotional entanglements, but it is not excluded that the murder was done for money. Or because there is a deep hatred between the deceased and the murderer, it may also be a homicide purely for the purpose of revenge.

"I don't know much about these situations, but I've contacted the Chiaki Yamaguchi Police Department, who used to be in charge of this case, and he is now retired and lives in Kofu City. How about it, would you like to visit the Yamaguchi Police Department with us if it's convenient tomorrow?" Kanako said enthusiastically.

"Is this convenient?" Lin Xiuyi really wanted to go, he really couldn't figure out how the trick of the snow secret room came out. What made Lin Xiuyi feel even more incomprehensible was that since the murderer had the ability to disappear out of thin air, why did he leave the murder weapon at the scene? Moreover, the murder weapon had to leave a bloody fingerprint on it.

"If you want to, we can't ask for it, but it's up to us to make trouble, after all, it's our job to come here to investigate the murder ten years ago, but we have been taken care of by you and your colleagues......" Kanako said sincerely.

"Xiu Yijun, we're back, I'm sorry to keep you waiting!"

After about ten minutes, Aizawa and Hanagata returned from under the bridge to the location where Lin Shuichi and the others were.

"How's today's harvest?" Lin Xiu greeted the two of them.

"If you ask about fish, it's not bad. If it's a treasure, it's still waiting for me!" said Hanagata. To be honest, Lin Xiuyi didn't believe that Hua Xing was really looking for treasure, although everyone was a young man of the same age, but Lin Xiuyi sometimes really didn't know what Hua Xing was thinking!

"Ah, your shoes are wet, change them quickly, or you'll get sick!" Miki reminded kindly when she saw the wet shoes of the two.

"It's okay, after going back to Umegaki House for a while, take a good dip in the hot spring, and there will be no problems!" Hanagata said and walked behind Aizawa to the back of the car. Sure enough, their shoes were wet from the stream. Leave one shoe print after another on the road. As soon as Lin Xiu heard Miki's words, he subconsciously looked at the shoes of the two people. Suddenly, he seemed to understand something!

Lin Xiuyi suddenly ran behind the two people excitedly, lying on the ground and carefully observing the footprints left by the two just now. It was as if I had realized something.

"What's the matter, Xiu Yijun!" Kanako saw Lin Xiuyi's strange behavior, and thought he was uncomfortable, so she hurried over to ask!

"Look, footprints!" Lin Xiuyi said excitedly, pointing to the footprints on the ground.

"Footprints, what's wrong with footprints?" Although Kanako knew that Lin Xiuyi was talking about the case ten years ago, he didn't understand what it had to do with footprints.

"It coincides, what if the murderer stayed in the Buddhist hall when Yamamoto Kengo arrived, and if he escaped by stepping on the footprints left by Yamamoto Kengo going down the mountain to report the crime......" Lin Shuichi explained for Kanako. He just saw that Aizawa, who was walking in front, left footprints, and then Hanagata stepped on it again. Lin Xiuyi's head was instantly enlightened.

"Ahh Kengo Yamamoto, who was the informant, inadvertently provided a way for the murderer to escape! The murderer only had to follow Yamamoto's footsteps to run out of the temple, and then hide in the nearby mountains, and wait for the police to go up the mountain before escaping in the chaos.

Kanako was also very happy to hear Lin Shuichi's assumption, but in fact, she didn't really want to re-investigate the murder case ten years ago. All Kanako needs is a gimmick of a secret room, and a reasonable escape room. Although Lin Shuichi's hypothesis has not yet been confirmed, it is enough for Kanako.

"Shuichi-kun, thank you, with your hypothesis, our script can start to be written!" Kanako and Superintendent Mizukawa said excitedly to Lin Shuichi.

"But this is just a hypothesis, and it hasn't been confirmed yet!" Lin Xiuyi cautiously reminded.

"It's okay, our goal is to produce a popular and excellent show, not to really solve the case......" Kanako explained to Hayashi Shuichi.

"Then ...... visit the Yamaguchi Chiaki Police Department tomorrow," Lin Xiuyi asked with some apprehension.

Kanako saw that Lin Xiuyi seemed to be a little lost, and couldn't help but feel a little unbearable, anyway, she had already made an appointment with the Yamaguchi Chiaki Police Department, so it was better to go and listen to what else was unknown about this case!

"We still have to go to the Yamaguchi Police Department, although the most critical escape room trick has been solved, but we still need more information to make the whole story more fleshed out......"
