"Let me analyze it. The person who stole the money was probably afraid I would find out, so they took it from the middle. They were probably nervous when they did it and didn't look carefully, so they took out the RMB and foreign exchange certificates together." A Lei's IQ is always on point.

"Who do you think did it? Isn't your door very secure?" Qin Xiaoyu couldn't think of anyone who could have done this.

"My door, you'll laugh when you hear it. In Cake's hands, no lock is worth a penny. It's so easy to open." A Lei gave a wry smile.

"It was your lover who colluded with someone from the inside," Qin Xiaoyu said irritably.

Joking aside, the thief absolutely must be found. Especially now that the analysis suggests it's an inside job, failing to find him would pose a huge threat.

My cousin's surveillance cameras came in handy again, but they were all installed at the entrance, so they could only see people coming in and out, and for privacy reasons, they couldn't see inside.

They checked and found that apart from Hanhan's grandmother coming in once, only people from Building 1 came and went; there were no other outsiders.

A Lei had already ruled out the possibility of someone entering through the window; the suspect was either a resident of Building 1 or Hanhan's grandmother.

Excluding Commander Zhou and his wife, Zhou Yue and her husband, and Qin Xiaoyu, who are definitely not suspects, that leaves the four children and Hanhan's grandmother.

“Although my mom is a bit absent-minded, she wouldn’t stoop to such a despicable act as stealing money. She usually doesn’t go upstairs either. As for these four kids, I’m not saying this to be rude, but Hanhan doesn’t lack money; her dad has given her plenty. My younger sister has been raised in luxury since she was little; she lacks nothing. She’s only been around for a couple of weeks, so she has no concept of money. As for Xiaojin and Lisheng…” Qin Xiaoyu knew that saying this was cruel.

"I've narrowed my suspicions down to Lisheng. Xiaojin isn't short of money, and after running away once, she's matured and knows what she can and can't do. If she needs money, she'll definitely find a way to get it from Zhou Yue. Lisheng has a habit of petty theft; I've seen him spend money before. Looking at Lao Deng and Zhou Yue, neither of them seem to be giving him a lot of money, so this money is probably of dubious origin."

Hearing what A Lei said, Qin Xiaoyu broke out in a cold sweat. She usually didn't keep track of her money, leaving her bag lying around carelessly; if someone with ulterior motives were watching, she wouldn't even know if money was stolen.

"What should we do? Sister Xiaoyue is heavily pregnant. Getting angry with her would only cause trouble. She's put so much effort into those two children. This is a blatant slap in the face; she can't take it." Qin Xiaoyu was troubled.

“Children’s education cannot be neglected. Opportunities are fleeting. Lisheng will soon enter adolescence. If we don’t take care of her now, will we be able to manage her in two years? You are responsible for Zhou Yue, so you have to make her face reality.” A Lei’s lawyer persona came online again.

"He won't admit it until we catch him in the act." Qin Xiaoyu hardened her heart; she was determined to rectify the family's conduct.

Before they could come up with a solution, something had already happened over there.

Dinner had just been set out when two uninvited guests arrived. The taller one was a woman in her thirties, broad-shouldered and with a face full of fat. The shorter one was a child, with two shiny snot dripping from his nose and his sleeves gleaming.

"I'm looking for Tang Zihan's parents!" The woman grabbed her son, who was wiping away tears, like a little chick, snatched a foreign exchange certificate from his hand, and slammed it on the table.

“This…” Zhou Xing’s mother was afraid of trouble and hurriedly stood up.

"What's wrong with Hanhan?" Commander Zhou was even more anxious than she was and hurriedly asked.

"Tang Zihan cheated my son out of his marbles with counterfeit money!" The woman said, turning around and punching her son, yelling, "Cry! What are you crying for! You're being bullied and you don't even dare to speak up! You coward!"

Qin Xiaoyu was shocked by her actions. What if the woman found out that it wasn't counterfeit money, but could be exchanged for 100 yuan? Wouldn't she regret it to death?

Hanhan was equally shocked; he stared in horror at the woman and child, too afraid to move.

"Hanhan! Did you do this?" Hanhan's grandma suddenly adopted a grandma's authority and shouted at Hanhan.

"I..." Hanhan panicked even more and didn't know how to answer for a moment.

Qin Xiaoyu glanced at the table and immediately understood: Lisheng had long since disappeared, and the kind-hearted Hanhan still wanted to protect her friend.

"What kind of parents are you! Speak up!" The woman couldn't hold back any longer when she saw them just staring at each other.

“Little boy, look up and see if Tang Zihan is among these people?” A Lei walked around the table, sat down next to the little boy, and asked softly.

"No." The little boy looked around, his gaze only lingering on Hanhan's face for a moment before immediately looking away.

"No?" Grandma Hanhan asked in confusion.

"Watch out! Don't cry to me if you can't find it, I won't buy it for you!" The woman was an adult, more cunning than a child. She stared at Hanhan as soon as she entered the room. Hanhan was the only child of similar age in the room. Seeing that her son didn't recognize her, she felt something was wrong and pressed him for an answer.

"No, really." The little boy refused to lie and cooperate with his mother, shaking his head.

"Tell Auntie what exactly happened?" Qin Xiaoyu walked over and asked softly.

"He said this money was foreign currency, very valuable, and he bought all my marbles," the little boy said, head down.

"He told you his name was Tang Zihan?"

"I don't know his name; I heard someone call him."

"Hanhan, come here." Qin Xiaoyu beckoned to Hanhan.

Hanhan hesitated for a moment before walking over.

Did you know about this?

Hanhan shook her head, then nodded hesitantly.

"Do you know or not?" Qin Xiaoyu pressed.

"Mom, I want to talk to you." Hanhan was on the verge of tears.

"Don't pressure the children anymore. Give them the money and let them go!" Commander Zhou said anxiously.

"Sir, this concerns Hanhan's innocence. We must find out the truth." Qin Xiaoyu stopped Commander Zhou.

"Stop pressuring Hanhan, it was Lisheng who did it!" Xiaojin stepped forward.

Zhou Yue's face suddenly changed color, and Deng Jianyan was also stunned.

Xiao Jin took Qin Xiaoyu to Lisheng's room to retrieve the glass ball and gave her a box of cookies before finally getting rid of the mother and son.

An unusually heavy atmosphere filled Building 4; everyone remained silent.

"Hanhan, did you know all along?"

"Mom, I was just guessing." Hanhan also started wiping away her tears.

"What are you saying about Hanhan! What did he do wrong!" Commander Zhou, protective of his own, was furious. He went over and pulled Hanhan to the sofa, comforting him tenderly.

"Come here and admit your mistake." Xiao Jin came out from behind, carrying Li Sheng. Deng Jianyan was furious when he saw him, turned around and rushed over, slapping him across the face.

Xiao Jin quickly protected her, and Zhou Yue also cried out and rushed over.

"Sister, slow down!" Qin Xiaoyu was so frightened that she went over to support Zhou Yue.

"Don't stop me! I'll kill him or I'm not a Deng!" Deng Jianyan was already furious. If it weren't for A Lei and Tang Long stopping him, Li Sheng would have been torn to pieces.
