"Dr. Ali, this is the hand gift I brought you from Hokkaido and ash plain. This is yours."

On the afternoon of the second day after his trip to Hokkaido, Bai Yan Zhenyu came to Dr. Ali's house and gave the gifts he bought to Dr. Ali and ash Hara AI.

"Eh, the mountaineering bag of Fu yarn painting brand."

Dr. Ali opened the gift box, took out a black and red mountaineering bag and said happily, "great, you can use it next time you go mountaineering."

"Thank you."

Ash Hara AI also opened the gift and found that it was the latest Scottish checked bag of Fu yarn painting brand. Her eyes were full of surprises and quietly thanked Bai Yan Zhenyu.

After the two people put away the gifts, Bai yanzhenyu told them the interesting things about the trip, and then asked, "how about the preliminary preparations for the research and development of ash, antidote? Do you need to add other instruments and consumables?"

"It's enough for the time being. After all, everything should start from the most basic place, and you can't use those high-end instruments."

Ash yuanai has made a research and development plan for the antidote, so he knows well the instruments needed in each stage and suggests: "however, several special instruments and consumables can be booked in advance, otherwise he may not be able to buy them in time."

"OK, you write me a list, and tell me in advance when you're not fast enough." Bai Yan Zhenyu made a phone gesture, indicating that ash yuanai can contact him at any time.

Ash Hara AI took out a pen and paper to write the list, handed it to Bai Yan Zhenyu, and suddenly said, "I remember one thing. A few years ago, my sister sent me several disks containing her travel photos. At that time, I transferred it out with the computer of the Research Institute and sent it back immediately. However, after that, I found that the disk storing drug data could not be found."

After listening to ash yuanai's words, Bai yanzhenyu looked happy and said along with his words: "that is to say, in the disk you sent back to your sister, there is likely to be the disk recording drug data, isn't it?"

"Well, it's very possible." ash yuanai nodded solemnly.

"If you can get it, it should help you develop an antidote faster."

Baiyan Zhenyu was very excited and couldn't wait to ask, "ash yuan, where is your sister's residence? We can look there."

"It's useless. With organizational prudence, everything in my sister's residence should be disposed of."

Ash yuanai shook her head helplessly. After thinking about it, she added: "however, my sister once said that the person who saved the photos on the disk was a university professor who traveled with her."

"You're right."

Baiyan Zhenyu expressed his understanding, but he didn't want to let go of this rare clue. He continued to ask, "do you know which Professor?"

After a moment of hard thinking, ash Hara replied, "it seems that it's hiroda Zhengsi, a professor at Nanyang University, but I don't know where he lives now."

"It doesn't matter. Just know who it is. Then give it to me."

Baiyan Zhenyu inquired about the telephone number of Nanyang University. After contacting Masashi hiroda through Nanyang University, he asked, "Professor hiroda, I'm a friend of Mingmei Miyano. She said that there were several disks for storing this travel photos before. Don't you know if the disks are still there?"

"Oh, you are Minmei's friend."

After learning that Bai yanzhenyu was Miyano Mingmei's friend, Professor Guangtian put down his vigilance against strangers and said with a smile: "I have returned the disks to others. Only one more disk is here. There are some strange contents in it."

"Great, what I'm looking for is the disk that Mingmei mistakenly sent you at that time."

Baiyan Zhenyu was determined and then asked, "Professor Guangtian, is it convenient for me to pick it up now?"

"Not now. I work outside. In the evening, I have to receive several guests... Well, come to my house after nine o'clock tonight."

Professor Guangtian is not at home. After making an appointment with Bai yanzhenyu to meet in the evening, he will tell Bai yanzhenyu his current address.

At more than 6 p.m., Bai yanzhenyu was going to go to Professor Guangtian's house alone to get the disk back. Ash yuanai said that she would go with her because she wanted to take the opportunity to relax.

Recently, in order to avoid the organization's pursuit, ash Hara AI has never been out of the door. Now after so many days, the organization has relaxed its pursuit of her. Therefore, Bai Yan Zhenyu agreed to ash Hara AI's request and took her to Shizuoka County, more than 100 kilometers away.

Near 9 p.m., Bai yanzhenyu and ash yuanai came to Professor Guangtian's house. A woman in her fifties, Professor Guangtian's wife, opened the door.

Bai yanzhenyu handed over the exquisite snacks bought from the store and said politely, "good evening, I'm Bai yanzhenyu who made an appointment with Professor Guangtian. Excuse me..."

Mrs. hiroda took the gift, smiled and replied, "so you are Mr. Baiyan? What a handsome young man. My husband has told me about you. Please come in."

Mrs. Hirota took them outside Professor Hirota's study, knocked on the door and shouted, "husband... A guest is coming, open the door..."

Mrs. Guangtian knocked for a while, but there was no response from Professor Guangtian. She was ready to take Bai yanzhenyu directly in, but she found that the door was locked.

"It's strange. What the hell is he doing inside? Why did he lock the door?"

Mrs. hiroda murmured and continued to knock on the door, but she never got a response from Professor hiroda.

Baiyan Zhenyu and ash yuanai looked at each other, and both saw a touch of doubt from each other's eyes and worry about professor Guangtian.

At this time, Baiyan Zhenyu found a row of small windows above the door, so he jumped up in situ and grabbed the window edge to observe the situation in the study.

The study was in a mess. Books, chess pieces, trophies and other items were scattered on the ground. A gray haired old man was pressed on the ground by the fallen bookcase. There was a pool of bright red blood on the floor at the back of his head.

Bai yanzhenyu's heart sank. He immediately jumped back to the ground and said to Mrs. Guangtian, "Professor Guangtian has an accident. Do you have a backup key to this room?"

"What?"

When she heard that Professor Guangtian had an accident, Mrs. Guangtian immediately got flustered and hurriedly replied, "I don't have a spare key."

"Then step back and I'll open the door."

Since there is no spare key, we can only break the door by violence. Therefore, after reminding the two people to leave, Bai Yan Zhenyu kicked the door open.

"Ah!"

The scene in the study fell into the eyes of everyone. After seeing professor Guangtian who didn't know his life and death, Mrs. Guangtian immediately screamed in horror.
