Su He frowned upon hearing this, feeling that the girl's behavior was a bit deliberate. Was she really just trying to get closer to her?

Su He didn't make a decision right away, planning to wait and see.

However, she was already quite satisfied with the detailed information she had received from Sister Liu.

Afterwards, we arranged a time to consult with Sister Yang, and then I went home first.

Once she got home and was alone, Su He began to ponder what aspects of these people were suspicious.

The first suspect is Jiang Wenxiu, the wife of researcher Sun. Although she acts flamboyantly, it is possible that she is pretending. Moreover, she often goes out shopping before, so it is possible that she is not going out to pass on information.

The second old lady, Mrs. Zhu, is quite old. Would a mole choose someone so old? Besides, Sister Liu said that since she arrived, she has spent most of her time arguing with her daughter-in-law and hasn't gone out much.

Of course, we cannot rule out the possibility that it is a disguise. After all, sometimes the most unlikely person is the most likely, so we also have doubts.

The third researcher, Yang Liu, is the same person as Su He. If she also thinks like Su He and uses this profession to convey information, then it would be too easy for her.

Moreover, she doesn't interact with many people, is better at disguising herself, and is not easily discovered.

Therefore, he is currently the person she suspects the most. Of course, we'll have to wait until we meet him to find out the specifics.

The fourth Tao sisters: the older sister rarely went out after arriving, staying at home to take care of her husband and children, while the younger sister was particularly active.

It's possible that her naive and eager-to-marry persona is also an act, with the aim of getting in touch with more researchers and obtaining more information.

The fact that they are now contacting the guards could be a way of sending messages out, which seems suspicious and requires further investigation.

It seems that these new families cannot be ruled out as suspects, in addition to other families, including family members who work outside and can go out openly every day.

Of course, the research institute had already investigated these people carefully, but Su He could not completely rule them out, since many moles and spies started training from a young age.

Including Dong Fang, whom Su He had met before, who would have thought that such an honest kitchen apprentice would be a spy that the enemy had been disguised as since childhood!

Therefore, she cannot let her guard down and overlook any possibility.

So, Su He roused herself and mentally reviewed the areas that needed to be observed. Then, seeing that it was almost time, she went to find Sister Liu again and asked her to introduce her to Sister Yang so she could learn from her.

Sister Liu warmly led her to the Zhang family's house at the end of the corridor, number 306.

When he arrived, he knocked on the door. As if afraid she would be nervous, he turned around and smiled at her, saying, "Don't worry, Xiao Yang may not be talkative, but he's a good person and will definitely help you."

Su He gave her a nervous smile after hearing this.

At that moment, the door to room 306 opened, and a tall woman came out.

She looked at the two of them with a puzzled expression before asking Liu's wife, "Did you come to see me for something, sister-in-law?"

Although her tone was somewhat cold, Sister Liu seemed unconcerned and explained with a smile:

"Is Xiao Yang busy right now? Let me introduce you. This is Xiao Hu, the new guy, Researcher Ji's wife. She lives in 303. She used to be a writer, and now she's come to Beijing and wants to make money with her pen, but she's not very familiar with this place, so she wanted to learn from you."

Sister Yang looked at Su He with surprise, then nodded to her.

Su He smiled at her, "I don't know if I've bothered you, sister-in-law. If you're busy right now, we can come another day."

Sister Yang shook her head. "No rush, please come in."
