Su He perked up and went to the cafeteria three times a day, carefully observing everyone who came and went, looking for anything amiss.

However, she guessed that even if there was still a mole in the research institute, they probably wouldn't meet in the cafeteria anymore. They were discovered last time, so the cafeteria would definitely be a key place to be observed this time.

Recently, the researchers seem to have sensed the tense atmosphere, eating in a hurry and rarely interacting with people outside their own families.

However, none of the households that Su He was mainly observing took any action.

She initially thought it was because the mole was too calm.

But just then, they suddenly heard the news that Tao Hong was going to be sent back to her hometown by her sister.

After investigating, Su He quickly found out the reason.

It turns out that Tao Hong couldn't find a boyfriend at the research institute, so she took a fancy to Xiao Zhang, the security guard at the gate, and often harassed him.

But Xiao Zhang already had a boyfriend, and he didn't give up even after being rejected several times. Eventually, Xiao Zhang's boyfriend found out and came over to scold Tao Hong.

Xiao Zhang's boyfriend is from the countryside. He is very strong and knows how to curse. His curses are particularly offensive. He made Tao Hong cry after just a few words and almost hit her.

Many people witnessed it at the time, so the matter caused quite a stir.

Tao Hong's brother-in-law, Researcher Cao, felt ashamed, so he forced his wife to see her off.

Tao Hong's sister had no choice but to see her off.

Su He frowned slightly upon hearing this. Was she leaving at this time because she had already obtained the goods, or because she wasn't the mole?

And Zhang's boyfriend also came over and had contact with her; it's hard to say he might have been passing on some kind of message.

So this matter still needs to be investigated.

So Su He sent out another submission.

A few days later, Captain Chen replied that Tao Hong had been investigated and there were no problems. She was sent back to her hometown after she left.

Her family felt ashamed of her and married her off to a local widower, where she was beaten terribly every day.

As for Xiao Zhang's girlfriend, she is an ordinary rural girl who is illiterate. She is strong and hardworking, but her family is large and has been poor for many years.

She and Xiao Zhang were betrothed when they were young, and now that she's reached marriageable age, she's waiting to marry Xiao Zhang and enjoy a life of luxury.

That's why she got so angry when she heard someone was trying to steal her boyfriend.

So far, the people sent out haven't found anything amiss.

Of course, it cannot be ruled out that this is all an act. Currently, these people are still accompanied by others to ensure that they are really okay before leaving.

The research institute also did not receive any information about the missing documents, so the possibility that Tao Hong was the mole was greatly reduced.

So Su He shifted her focus to other people.

At this time, another family moved into the residential compound. It was a young couple. The man's surname was Li. He had worked at the research institute before and had just gotten married.

After moving in and settling in, I planned to treat everyone to a meal.

Because it was room 301 on their floor, Su He was also invited.

She accepted the offer without hesitation, and on the appointed day, she and Sister Liu visited the house together, bringing the gifts.

After entering, I greeted the young couple. The new bride's surname was Dong, and her name was Dong Yue. Surprisingly, she knew Yang Liu.

Yang Liu had arrived before they did.

Seeing Su He and the others' confusion, Yang Liu took the initiative to explain: "Dong Yue is my sister's classmate and also our neighbor. She used to come to my house to play often."

After hearing this, Dong Yue smiled and said, "Yes, Sister Yang is a famous talented woman in our area. I admired her so much when I was a child. I never thought I would become her neighbor. This is wonderful."

Everyone smiled kindly upon hearing this.

Su He was the same, but she was wondering if the newcomer Dong Yue was suspicious and if she had any purpose in moving in at this time.

And since she happens to know Yang Liu, is she here to meet her?

Of course, none of this is clear at the moment. Su He harbored doubts, but outwardly remained calm as she probed for information...
