Zhaodong Ihe and meidaiko Watanabe have their own houses. When Nagoya Watanabe was alive, they lived in their own houses, and only occasionally went back to Nagoya Watanabe's house. Chen Hui's proposal, let shijingxiohiko to investigate his family, naturally, is to investigate meidaiko Watanabe's family.

Shijingxiohiko on the other side of the phone is silent, obviously hesitating. I don't know if I should go to meidaiko Watanabe's house to check.

Shijingxiongyan did not speak, Chen Hui did not speak, the phone, the two so kept silent.

"Dr. Chen." Ishii asked in a low voice, "why do you make such a suggestion? Or are you very skeptical of him? "

"I would suggest that because of the surveillance video you found." Chen Hui said: "after he left the company, he went to meet Mr. Watanabe. He left the company early, but he arrived at the airport half an hour late. During this time, no one knows what he did. When you check here, you find that they both appeared in the same gas station at the same time. It's a coincidence."

After a pause, Chen Hui asked again, "I'll ask you a few questions now."

"Excuse me." Ishii said immediately.

"Is this gas station on the way to the airport?" Chen Hui asked the first question.

"It's not easy to answer this question. The gas station is on the east-west road. There are full intersections on the left and right. You can turn to the road to the airport." Shijingxiongyan very specific answer: "that gas station, far away from the airport, probably in the city to the airport in the middle of some position."

"Second question, where is the location of IHA pharmaceutical?" Chen Hui asked with a smile.

"Doesn't Dr. Chen know the address of Yihe pharmaceutical company?" When Ishii finished saying this, a bright light flashed across his head and asked, "what does Dr. Chen mean?"

Chen Hui interrupted shijingxiongyan and asked, "apart from this gas station, is there no other gas station close to Yihe pharmaceutical?"

"Yes!" Shijingxiongyan nodded, said: "several!"

"How can Ihe Baishi's car go so far to refuel?" Chen Hui said with a smile: "it's nothing to go to the gas station. Maybe it's Yihe Baishi who went out to talk about business. Passing by the gas station, the car just ran out of gas. However, Yihe Zhaodong also appeared in the gas station. This coincidence is what I just said. It's too much coincidence, isn't it?"

"I see." Shijingxiongyan nodded and said: "I'll go to miss Watanabe's home to check it!"

"Another reason is that what Mr. Ishii is doing now is similar to looking for a needle in a haystack." Chen Hui said: "don't dig deep for the cable. Besides, Mr. Ishii can get into Yihe Baishi's house. Isn't it easier for Miss Watanabe's house? Take Miss Watanabe's key secretly and just go there! "

"I'll do it without a trace." Ishii said in a low voice.

"I'll be able to finish the topographic map of the company in a moment, and I'll mark the surveillance cameras in the company with red dots." Chen Hui said: "topographic map, I still hide in the toilet water tank of the music bar bathroom. Mr. Ishii sent someone to pick it up."

"All right!" Shijingxiongyan immediately agreed to come down, asked: "Doctor Chen, what suspicious location can be found?"

"The security of the whole Yihe pharmaceutical company is actually very general." Chen Hui thought about it and said, "the R & D center is well guarded, but it's understandable. After all, the R & D center is the core area of a pharmaceutical company, and it's normal for the security level to be higher. If there is any suspicious location, I think it will be in the R & D center. The R & D center's laboratory is underground, but I was trapped in the laboratory last night, I didn't get around the R & D center! "

"It's really embarrassing for Dr. Chen." Ishii said with an apologetic tone.

"Nothing." "If I find anything, I will contact Mr. Ishii in time," Chen said

Chen Hui said this, obviously ready to hang up, but Chen Hui suddenly thought of something, said: "wait!"

"What's the matter?" Ishii asked as he left.

Chen Hui pondered for a moment and said, "is the logo of Yihe pharmaceutical company a triangular pattern?"

"Yes, the one outside their office building!" Ishii immediately said: "the outer packing box of the drugs produced by their company has that mark."

Chen Hui said, "when I entered the R & D center last night, there was a wall on the opposite side. On that wall, there was a sign similar to a circle, which was totally different from the logo of ihe pharmaceutical company. I don't know what happened!"

After a pause, Chen Hui said: "I mentioned this because I feel that the logo looks a little familiar, similar to one of the mahjong cards!"

Hearing what Chen Hui said, Ishii pondered for a moment and said, "could you please Dr. Chen draw that sign? When I go to get the topographic map, I'll bring it back together and study it? "

"No problem." Chen Hui nodded and said, hung up the phone, took a blank piece of paper, drew the pattern on the white paper with memory, and indicated that it was just the general appearance. The specific details may differ. After all, the pattern is very complicated.

After Chen Hui finished painting, Zhou qiuchu took it over, looked at the pattern and said, "don't mention it, it's really like a mahjong."

After a pause, Zhou qiuchu said, "you just said that this logo is in the R & D center of Yihe pharmaceutical company?"

"Yes, after going in, on the opposite wall." Chen Hui said with a smile, "it's about this big!"

Chen Hui depicted a circle with a diameter of 50-60 cm. Zhou qiuchu frowned and said, "is it true that there are other companies in Yihe pharmaceutical company that have shares?"

"I don't know!" Chen Hui said: "shijingxiongyan will go to check."

"Let's go to the music bar for a drink, and then put the map and the pattern in the water tank of the toilet." Zhou qiuchu said at this time.

Chen Hui nodded, got up and went to the music bar with Zhou qiuchu, ordered a bottle of wine, had a few drinks in the bar, got up to go to the toilet, and put the two pieces of paper into the water tank of the toilet.

After all this, Chen Hui returned to his position and sat down again. After drinking the wine with Zhou qiuchu, he immediately went back to his room to have a rest.

Chen Hui has been busy all night. Naturally, Zhou qiuchu won't disturb his rest. At lunch time, Zhou qiuchu asked Chen Hui. Chen Hui didn't eat lunch directly and didn't let Zhou qiuchu bring it to him. Zhou qiuchu went to the restaurant for lunch alone.

Mobile phone was as like as two peas at four p.m., Chen Huishui's incense, the phone was ringing, it was the cell phone that Ishii Ohiko had prepared. Chen Hui saw a message and opened it. It was a picture of a circular pattern, which was exactly the same as the one on the wall of the company.

However, the circular pattern in this photo is not the iconic pattern on the wall of ihe pharmaceutical company, but a real photo. It is a metal product with a diameter of about 45 cm, which looks like an ornament!

Chen Hui showed Zhou qiuchu this picture, and immediately made a phone call to Ishii Xiongyan.
