Even if there's a floor above her house that leads directly upwards, where else can you go once you reach the top floor?

Even the most naive woman could sense something was wrong. As she took out her keys to open the door, she asked, "Miss, who are you looking for?"

Sun Hui reacted relatively quickly. She could only try to bluff her way out of it. Even if she guessed wrong, it didn't matter; she could just say she misheard. She said, "I came here to see a friend. He said his home is on the 6th floor of building number 3, facing east. How come it's your home?"

It's quite normal to go to the wrong house when visiting a friend, and the woman didn't seem to mind. She said, "Miss, you've gone to the wrong building. This is building number one."

This time, she was right. Sun Hui said, "I'm sorry, this is my first time visiting a friend's house."

The woman said, "It's alright, go look in Building 3!"

Sun Hui said thank you and turned to walk downstairs.

Sun Hui returned to the company, went into the deputy general manager's office, and explained the results of her investigation to Li Yuzhu in detail.

Then she took out two photos taken in the mall. Li Yuzhu had provided all ten of them with cameras that could take photos in one go. These cameras didn't use film, and the photos could be taken directly afterward.

Li Yuzhu compared the woman's photo with the photos she had previously developed, and found an 80% similarity. Whether it was really this woman was hard to say.

Li Yuzhu suddenly remembered something and asked, "How old do you think that woman is?"

Sun Hui said, "She's about 30 years old."

That doesn't match the age; the woman in the video looks to her at most twenty-five. She said, "That woman already knows you, so you can't follow her anymore. Don't worry about this, I'll handle it myself."

What Li Yuzhu said was also true. Sun Hui had met the woman before, and she could recognize her after meeting her again. Even if she followed her, she would not be able to do anything because the woman could recognize her as soon as they met.

Sun Hui said she had arrived and turned to leave the office.

After Sun Hui left, Li Yuzhu left work early and walked out of the office.

She went home, turned on the TV and VCR, took out the videotape, put it into the VCR, and casually pressed the play button.

The video was short, but she watched it more than a dozen times.

The woman in the video is not that old at all; she is at most twenty-five years old, which does not match the thirty-year-old age Sun Hui mentioned.

Li Yuzhu decided to investigate the matter herself and start with this woman.

There are many people in the world who look alike. It is impossible to look so alike without any blood relation. In Li Yuzhu's opinion, the woman Sun Hui found was at least the older sister of the woman in the video, otherwise they would not look so alike.

After lunch, Li Yuzhu said, "Honey, I have some things to take care of these next few days, so I won't be going to the company. Could you help me with anything?"

Dong Qing didn't ask his wife what was wrong. He said, "You go ahead with your work. I'll handle the work for you."

Before 1 p.m., Li Yuzhu drove to the residential area mentioned by Sun Hui and parked her car on the side of the road outside the residential area.

Entering the community won't work; you can only wait outside the gate.

She decided to wait outside the gate of the residential area for the woman to come out. Waiting blindly like this didn't offer much hope; who knew if she would even go out this afternoon?

They waited until after 4 p.m. but the woman still hadn't come out.

There are only three possibilities: First, it's Sunday and she's resting at home instead of going to work; second, she's a full-time housewife who doesn't work.

She's not working and should be at home taking care of her children, but why didn't she take them with her when she went to the mall this morning? Did she leave the children at home?

Of course, there are many reasons for this. First, she is single; second, her child was sent to her parents' hometown; and third, she and her husband did not have any children after marriage.

The third possibility is simple: she had already left when I arrived, and if that's the case, she'll definitely come back at night.

Just as Li Yuzhu was lost in thought, she suddenly saw a woman riding a motorcycle out of the residential area. After comparing the photos, she could easily tell that she was the woman in the photos. She quickly started her car and followed her.

Li Yuzhu followed them to an urban village.

She drove into the village, and the woman in front drove her motorcycle into a small alley.

Li Yuzhu could no longer follow them after they reached this point, so she pulled the car over to the side of the road, got out, and walked into the alley.

The alley had many bends, and Li Yuzhu didn't know which way the woman had gone. She could only search everywhere, and as long as the motorcycle was parked outside the gate, it wouldn't be difficult to find her.

After searching for a long time, they finally found the woman's red women's motorcycle in front of a house gate.

It is a house with a courtyard. The courtyard doesn't look very big. There are two three-story buildings inside.

Too many people in this city know Li Yuzhu, and women would probably recognize her immediately. She took out sunglasses from her bag, put them on, and then put on a large mask so that no one could recognize her.

Of course, she couldn't wait at someone's front door, so she stood far away.

The front door opened before dark, and a woman escorted her out of her house; the distance was too great to see the woman's face clearly.

Li Yuzhu hurriedly squatted down, untied the shoelace on her right foot, stood up, and walked towards the two women.

Upon closer inspection, I could clearly see the other woman's appearance. She was about the same age as the woman in the video, around 25 years old, and she bore at least 90% resemblance to the woman in the video.

The two women were talking outside the gate. Li Yuzhu approached, squatted down to tie her shoelaces, and heard the woman say, "Third sister, you're not young anymore. You were born late and are already 25. How long can you continue this ambiguous relationship with him? He's a married man with children. I don't want you to marry an old man. Listen to me, find a good man to marry quickly."

The younger sister said, "Big sister, how many times have I told you before you believed me? He and I broke up more than a month ago."

The eldest sister said, "That's what I hope for. I wish I could find someone and get married soon."

Li Yuzhu understood everything at this point. Her sister was someone else's mistress, and from all perspectives, she was the most suspicious. Her ex-lover was probably the mastermind behind it all.

Li Yuzhu heard nothing more to hear, so she finished tying her shoelaces, stood up, and continued walking forward. Then she heard the sound of a motorcycle engine; her sister had already ridden her motorcycle home.

Li Yuzhu looked back and saw that the woman had already gone home.

Li Yuzhu took off her mask and sunglasses, went back to her female neighbor's house, and knocked on the door.

A middle-aged woman opened the door and asked Li Yuzhu, who was standing outside, "Young lady, who are you looking for?"

Li Yuzhu said, "Sister, if it's convenient, could I come in and have some water?"

The woman said, "Of course," and stepped aside to let Li Yuzhu into the house.

When the woman poured water for Li Yuzhu, Li Yuzhu took out 500 yuan from her bag and handed it to the woman, saying, "Sister, I don't want the water. I want to ask you about something. Can you promise not to tell anyone?"

Five hundred yuan was a considerable sum in those days. The woman took the money and said, "Go ahead and tell me. I won't tell anyone, no matter what it is."

Next, Li Yuzhu asked about the neighbor woman's situation.
