"Her? Who is she?" Hu Xing asked curiously.

Qi Yang was silent for a moment, then said, "It's Zhu Xiaolian's daughter."

Su He nodded. "Yes, it's her. Since that person came to deliver the letter, besides Zhu Xiaolian, her daughter must have also seen it. But the child is only seven years old. According to Zhu Dayong, the little girl has changed completely since her mother's accident. I don't know if she can still remember."

Upon hearing this, Jiao Weimin immediately said, "A seven-year-old child can remember things now, so he might actually know. We can go and ask him."

Su He thought so too, "Then leave it to me. I'm a woman, so it'll be easier for me to ask questions."

After hearing this, no one had any doubts, and the matter was settled.

So in the following days, Su He would take time to visit Zhu Xiaolian's daughter at Zhu Dayong's house.

Zhu Xiaolian's parents are still alive, but both of them are in poor health. After their daughter's accident, they fell ill due to grief.

So Zhu Xiaolian's daughter was raised at her younger brother Zhu Dayong's house.

Su He visited several times and found that the little girl probably knew that her mother had an accident. She had become very timid and was not very willing to see outsiders. Every time, she would hide in a corner and play by herself.

Su He was also a mother and knew that she couldn't force the child, so every time she went there, she would bring a lot of good food and then quietly stay by her side. Over time, this made the little girl relax a lot and willing to let her play with her.

After persisting like this for a few days, Su He felt it was about time. After playing with her for a while, she took out a stack of photos.

Some of these photos were found at Zhu Xiaolian and Yan Xiangdong's homes. There were photos of the two of them together, as well as photos of them with colleagues and friends. Some of these photos were collected by the Municipal Bureau from people who had interacted with the two of them during this period. Of course, it is not complete, but this is all they have collected. If that doesn't work, they will have to think of other ways.

After Su He took out the photo, she asked her to identify it. "Niu Niu, Auntie needs your help with something. Can you help Auntie take a look?"

Zhu Xiaolian's daughter, whose full name is Yan Mengshu and nickname is Niuniu, looked over upon hearing this. Although she didn't speak, Su He had a general understanding of her thoughts after spending the past few days with her, and it seemed that she had agreed.

Seeing this, she finally felt relieved.

So, she laid out the photos one by one and asked, "Niu Niu, do you remember who came to our house a while ago and told your mother about your father's business trip?"

After hearing this, Niu Niu frowned and remained silent for a long time.

Su He thought she had forgotten, but then she suddenly noticed that her hand moved and pointed to someone in a group photo.

Seeing this, Su He became a little excited and quickly asked to confirm, "Niu Niu, you mean it was him? He told your mother that your father went on a business trip?"

Niu Niu nodded. "It's Uncle Liu."

Su He was surprised that she actually knew and, somewhat incredulous, asked again, "Really? Is Niu Niu sure it was him who went to see your mother?"

Niu Niu nodded, "It was Uncle Liu. Mom was in a bad mood after he left that day!"

As she spoke, she seemed worried that the woman wouldn't believe her, and her eyes welled up with tears, as if she were thinking of her mother again.

Su He quickly comforted her, "I believe you, Niu Niu, don't worry, Auntie believes in you. Niu Niu is really amazing, you've helped Auntie a lot this time!"

Niu Niu felt a little better after hearing that.

Su He was in a hurry to get back, so she said a few more words to her, promising to come see her again, and then quickly left.
