Zhang Kaiyuan didn't speak again, and led the two of them through the courtyard to the house.

"Professor Lei, do you usually live alone?" Shu Ran asked. Since I first came in, I haven't seen anyone else except Zhang Kaiyuan. And in this room, there is also a portrait of an old lady. Looking at it like this, this should be Zhang Kaiyuan's deceased wife.

"That's right." Zhang Kaiyuan replied: "Now I live alone, and my children are all abroad." Three years ago, this wife also passed away. ”

As he spoke, Zhang Kaiyuan focused his attention on the stamp album in Tang Shuai's hand. Suddenly, his eyes lit up. "You brought the album and let me see it."

This old man is so keen on stamp collecting, maybe this will be a breakthrough.

Tang Shuai didn't know anything about this, and Han Yi helped find this stamp album.

Handing the stamp album to Zhang Kaiyuan, he held it carefully. It seems that he is holding a precious porcelain, for fear of falling.

Look at him as he opened the album with excitement on his face, turning through the pages one by one. But slowly, the excitement on his face was gone. The brow was also locked, and in the end, there was a look of disappointment.

"You've said it, you're a beginner yet, and I thought you had any good stamps. You're just a few pieces of paper at best, but it's not bad, and it's not bad for collectors like you who are just getting started. Then Zhang Kaiyuan returned the stamp album to Tang Shuai.

Looking at it like this, these stamps can't get into the eyes of Zhang Kaiyuan. It doesn't matter, it's just to fool him anyway. And now, it seems to have flickered. Next, just talk to him casually and grab his attention. Then let Shu Ran take pictures.

In fact, now that Shu Ran has entered the role, he has begun to take out his mobile phone and sit down to play with it. In fact, Shu Ran is not usually a low-headed person, she only holds her mobile phone when she makes a call. But today, at Tang Shuai's request, she couldn't help it.

She didn't know what was wrong with her, she would promise Tang Shuai to help him do this kind of thing. This is a candid photograph, an immoral act. But in the face of Tang Shuai's request, I felt that I just couldn't refuse.

"Professor Zhang, I'm just a beginner. You can't even tell the quality of the stamps, and it's naturally impossible to take out the stamps that can fit your eyes. Why don't you show me the stamps you collected, and let me see them. Tang Shuai said.

"You wait." Zhang Kaiyuan said and entered a room. After going, lock the door. This old man is very cautious.

"Ranran, wait a minute, you can start."

Shu Ran glared at Tang Shuai fiercely. "I don't even know why I'd help do such a thing."

"Ranran, do the two of us still have to worry about this?"

"Why don't you care? Hum. ”

Before Zhang Kaiyuan came out, Tang Shuai was sitting on the sofa and kicked on the ground. There were two empty sounds, which shocked Tang Shuai. Could it be that there is really an underground research room underneath? If this is true, then the possibility that Zhang Kaiyuan is the Professor Lei they are looking for is greatly increased.

If there is an underground research room, then you must find a way to find the entrance. Then find an opportunity to sneak in, and in this case, the truth of Yiqiē will be revealed.

At this moment, Zhang Kaiyuan walked out with a postal booklet.

"Look, of course, I don't expect you to see their value." Zhang Kaiyuan did not directly hand over the stamp album to Tang Shuai, but he helped Tang Shuai open it.

Looking at the stamps that were carefully packed in the mail bag, Tang Shuai did see what value they had. Say I'm all the same, don't I think you're all the same?

"The red print is a circle, and this can be said to be the only one in the world. There is also this full-page 80-edition monkey ticket, which is also worth a lot of money. At this time, Shu Ran came over.

"Hey, you know that, too?"

"I know a little bit about it."

"Haha, I finally met a soulmate. Come on, you appreciate it slowly, I'll pour you tea. With that, this Zhang Kaiyuan directly handed the stamp album to Shu Ran.

Tang Shuai feels that this is unfair, Lao Tzu wants to see you and hold it in his hand, for fear that I will touch it. And now, directly stuff it to Shu Ran.

"Professor Lei, no need."

"It's okay, you wait, it'll be ready to soak right away."

"Hey, you still know about stamps?" Tang Shuai asked.

"I've said it all, I know a little bit about it. So, I'll do the work that gets his attention. And to take pictures, you go yourself. I really can't do this kind of thing. ”

It seems that he is very reluctant to take candid photos, and Tang Shuai has no choice now. Judging from the current situation, Shu Ran seems to be more able to find a topic with Zhang Kaiyuan. In this case, he can only come to the job of taking pictures. It's okay to come in person, but it's always reassuring to come in person.

Soon Zhang Kaiyuan came over to make tea, but this was only one cup, which completely excluded Tang Shuai.

Of course, it's obviously not the time to dwell on this, hurry up and take pictures, take pictures well, and leave with Shu Ran to eat. Looking at the old man's appearance, it seems that he has no intention of inviting them to dinner here.

Zhang Kaiyuan chatted with Shu Ran, and the two of them chatted very happily. Sure enough, this stamp is a breakthrough for Zhang Kaiyuan. In this way, there will be more places to use Shu Ran in the future. At least for now, only she can talk to Zhang Kaiyuan.

And now, Zhang Kaiyuan didn't pay attention to Tang Shuai at all. Tang Shuai took out his mobile phone and pretended to be playing with it. Then look around and take pictures secretly.

Zhang Kaiyuan's home is very large, and it is not easy to shoot every place. After half an hour, he finally finished filming the places he could go, and the next thing was the bedroom.

Tang Shuai walked to the door of the bedroom and opened it gently.

"What do you do?" Suddenly, Zhang Kaiyuan yelled. "What are you going to do in my dormitory?"

"No, no." Tang Shuai hurriedly said, "I'll find a toilet." ”

"The toilet is in front, and my bedroom looks like the toilet?"

"No, no, I'm sorry." Tang Shuai hurriedly ran into the toilet. In this way, it is impossible to enter the dormitory directly from the main entrance to take pictures. But when Tang Shuai opened the door just now, he saw that the window was open, as long as he walked into the courtyard and climbed in through the window, could he do it for a while?

"Shoot the toilet first." Tang Shuai thought in his heart. Then I took two pictures of the toilet with a "click, click". Although do not think that the toilet is anything suspicious. But it's better to be cautious. Give the photos to Han Yi, and leave the analysis to them. I took pictures of all the corners, whether it was useful or not, so that I wouldn't come back and reshoot. In case something misses and is asked to come back and shoot again, it will be troublesome.

After one contact with this eccentric old man, I don't want to have a second contact, so I still do something right one time.

"I'll go for a walk around the yard." After coming out of the toilet, Tang Shuai said to the two people in the living room. However, these two completely ignored Tang Shuai and just cared about them chatting happily.

This is just right, Tang Shuai walked out of the living room and came to the courtyard.

Walk to the window of Zhang Kaiyuan's bedroom, and enter from here, Zhang Kaiyuan will not know.

Easily rummaged in, this room is not big, and there is very little furniture, only a bed and a wardrobe. It looks very neat.

Tang Shuai hurriedly took out his mobile phone and began to take pictures. Every corner is taken, and then the whole room is photographed. It took less than a minute to finish.

Then Tang Shuai went out of the window, and then went back as if nothing happened.

"Ranran, it's not too early, let's go." As soon as it was over, Tang Shuai was also ready to ask Shu Ran to leave. I'm still hungry, I should go find something to eat.

Shu Ran looked at the time, it was not early.

"Professor Lei, let's go first. Next time, let's talk about this stamp. ”

"Okay, okay, go slowly, go slowly."

Zhang Kaiyuan's attitude towards Shu Ran is very good, sure enough, as long as he grasps this breakthrough, he is still easy to get along with. It's okay to have a common topic with him, but Tang Shuai really doesn't know anything about stamp collecting.

"How's the photo going?" After leaving Zhang Kaiyuan's house, Shu Ran asked Tang Shuai.

"Okay."

"Tang Shuai, what are you doing taking these photos?"

"It's a secret, Ran Ran, there are still some things that I can't tell you about yet. I'm so hungry, let's find a place to eat. I know, you don't like to go to a restaurant to eat. But it's not too early now, and you won't be able to go back to work in the afternoon if you want to go back to cooking. ”

Tang Shuai is right, it's not early. Shu Ran also agreed to Tang Shuai's suggestion to find a restaurant nearby.

After eating, Tang Shuai sent Shu Ran back to school. And he contacted Han Yi and asked her to get the photos.

After Han Yi came over, he looked at the photo and copied it with a USB flash drive.

"This time it was a good job, and after such a long time, you have finally done something useful. We'll take this picture back and analyze it, so stay by for now. If there is a new task, I will communicate it to you. Han Yi said.

"Okay." Tang Shuai nodded.

"I'm leaving."

"Are you ready for the evening?"

"No problem."

"Alright, thanks."

Han Yi didn't say anything more and left directly.

Evening.

Tian Xin finished a day's work, and Tian Xin didn't have to worry about Chen Ba's murder. After all, Han Yi knew the situation, and it was impossible for them to investigate anything. Therefore, Han Yi used their identities to make them stop the investigation.

"Tian Xin." Suddenly, Tian Xin heard someone calling her. Looking back, the expression on this face was a little displeased. The person who called him was her old classmate, Zhou Mei. I didn't expect to see her again, and the last time we met, we broke up unhappily. His boyfriend Wang Peng, who was originally Chen Youyi's bodyguard, also lost his job.

It stands to reason that she should hate Tian Xin very much, and now she greets Tian Xin with a smile on her face, which seems abnormal.
