Ke Xue: Shinichi and I are childhood friends

Yuya returned to the living room, glanced at the few people who were still waiting, and said, "It's late today, let's go back to the room and sleep."

"Young detective, do you know who the murderer is?" Mr. Itai asked in fear, curled up in the sofa.

Yuya shook his head: "Sorry, time is limited and I haven't locked the murderer yet, but I have found some evidence. Believe me, I will find the murderer soon."

"Is that so..."

Everyone was a little disappointed to hear that the murderer was not found, but the heavy sleepiness had troubled them for a long time, so they could only go back to the room to rest.

Yuya looked at the backs of the people leaving and suddenly said, "Mr. Fei Se, what happened to your hand?"

There was a band-aid on the back of his hand. Yuya remembered clearly that his hand was not injured when he was listening to the story. When...

Fei Se's footsteps stopped suddenly, subconsciously retracted his hand, and replied in a low voice: "Nothing, accidentally scratched."

Yuya said slowly: "Is that so... Be careful to treat the wound to avoid infection. After all, if you are scratched by rusty iron, it is easy to get tetanus."

Fei Se nodded and replied: "Thank you for your concern, but I was not scratched by any rusty iron."

Yuya did not speak again, but a trace of thought flashed in his eyes.

Fei Se turned his head slightly to look at Yuya, and then went back to the room.

···

On the platform of the stairs, Yuya looked up at the portrait on the wall in a daze.

"What are you thinking about?" Miyano Shiho walked over.

Yuya said: "The murderer's method has been cracked, and I roughly know who the murderer is, but the key evidence has not been found yet."

"I speculate that the evidence may be with the murderer, but I am not completely sure..."

"Oh? If you are not completely sure, then?" Miyano Shiho smiled.

Yuya was stunned for a moment, poked her soft cheek with his finger, and said with a smile: "This is not just my catchphrase, but also shows that I have sufficient evidence and clues, and I have connected them all together."

Miyano Shiho tilted her head and asked: "So, now there is still one piece of evidence, right?"

"Yes, without evidence, the murderer cannot be identified, and then all my reasoning will not stand."

"In this case... why don't we sort out the case from beginning to end? See if there is anything missing?"

"Okay..."

Yuya pondered: "First of all, the time of the crime should be between 9 and 10 o'clock.

At that time, everyone was in the room, only the murderer and the deceased were in the bathroom on the first floor... To be precise, the crime should have occurred after 9:05, because I watched here for a while "I saw this portrait of my son, but I didn't see anyone coming out."

Shiho Miyano continued: "There are salt crystals on the collar of the body, which can be inferred that the first crime scene is the bathroom. The murderer should have killed the deceased in the bathroom on the first floor, then drained the blood into the bathtub, and then used that passage to transport the body back to the room on the second floor."

"Finally, Mrs. Oishi found a pool of blood in the bathroom on the first floor. I noticed that the dean did not show up, so I suspected that she was killed. As a result, the body was indeed found in her room."

"In addition to the salt crystals on the body, there are also pigments left by nail polish at the end of the nails, but the removed nail polish was not found in the luggage. I suspect that it was taken away by the murderer, and there may be a key to incriminating the murderer on it."

"So, our current goal is to find those nail polishes?" Shiho Miyano concluded.

Yuya nodded: "Manicure should be the most critical evidence, but a lot of it may have been disposed of by the murderer in the meantime. And what I am more concerned about is, did the dean go to the bathroom by himself, or was he called there by the murderer?"

There was one sentence that Yuya didn't say, that is, if it is related to the bizarre death of Kaori Wada six years ago, maybe the dean played a role in it, and the murderer had some evidence and threatened the dean to go to the bathroom?

Thinking of this, Yuya pondered: "Perhaps, we can find out what happened back then with Shin Yuyama."

"Hmm?" Miyano Shiho's face showed a trace of doubt. Why did Shin Yuyama suddenly mention Shin Yuyama?

The two came to Shin Yuyama's room and knocked on the door.

"Who is it?" Shin Yuyama's doubtful voice came from inside.

"It's me, Kamiya." Yuya said.

After a while, the door opened, and Shin Yuyama's pale face appeared behind the door.

He looked at the two of them and asked nervously, "What's going on?"

Yuya said, "I want to find you to find out what happened six years ago."

Yayama Shin's face suddenly changed."I don't know, I don't know anything!" He tried to close the door.

Yuya raised his hand and pressed against the door, whispering: "Mr. Yushan, the dean has been killed, and the murderer's next target is likely to be you!"

"Then find the murderer quickly! Aren't you a detective!" Yushan Sheng asked in panic.

Yuya sneered: "That's why I want to find you to understand what happened back then."

Yushan Shen's eyes suddenly widened, his lips trembled for a long time, and finally let go of his hand: "I know, you come in."

Yuya and Miyano Shiho looked at each other, and then walked into the room.

"Tell me, what do you want to know?" Yushan Shen sat on the bed in a daze.

Yuya thought for a moment and said, "Mr. Yushan, if I'm not mistaken, Kaori Wada's death was not caused by a vampire, but someone drained her blood for the rare Bombay blood?"

Shin Yushan's pupils suddenly shrank into a small dot, and he looked at Yuya in horror: "You, how did you know?!"

Yuya sighed deeply, and it was just as he guessed.

Yu Shanshen stared at the floor with a dazed look in his eyes. He said, "Six years ago, a wealthy couple came to the mountains to play. As a result, the wife accidentally fell off a cliff. When she was sent to the hospital for emergency treatment and needed a blood transfusion, we found that her blood type was the extremely rare Bombay type.

How could a small hospital like ours in the mountains store blood of this type? Even if we urgently transferred blood from other places, it would be too late. The wife could only wait to die...

At that time, I accidentally let it slip that Kaori Wada also had Bombay blood.

The man was very rich and hinted that he would pay any amount of money as long as he could save his wife.

I, I was against it at the time! Because That woman lost too much blood, and the amount of blood she needed to be transfused was enough to kill Kaori Wada in her physical condition!

But the dean said...she said that Kaori Wada's heart disease was so serious anyway, and there was no money for a transplant, so she would die sooner or later, so why not..."

Yuya's eyes turned cold, and he shouted: "So you deprived a young life just for money?"

Yayama Shin's body trembled violently, and he shouted: "I don't want to do this either! The dean said to do this!"

"Two hundred million, that's two hundred million!" Yushan Shin shouted, "I'm a doctor in a small hospital, how many years do I have to work to earn that much money? !"

Yuya was so angry that he laughed, a mere two hundred million? Not to mention Suzuki Sonoko, even with his family background, he doesn't care about this little money.

Miyano Shiho gritted his teeth and cursed in a low voice: "Devil!"
