After the return of the real daughter, she has doubled

Jiang Jingan said proudly: "Of course."

They all envied Jiang Jingan for having such an excellent and beautiful sister like Jiang Zhi.

The look towards him was somewhat envious.

Jiang Jingan was very pleased with this look, and he was very proud of himself. Humph! Are you envious? Go ahead! Anyway, she is not your sister. Jiang Zhi will only be his sister! !

"That's enough! There's no point in being envious!" Jiang Jing'an dismissed them, "Hurry up and go research. Have you finished the project? Have you completed your part? Hurry up and get to work!"

With just one sentence, he defeated everyone except Jiang Zhi.

They returned to their workstations dejectedly and continued their experiments. Compared to them, Jiang Zhi had more free time and could look around.

Soon, everyone discovered that Jiang Zhi was not only good at mathematics, but also understood a lot of professional knowledge in physics and could even give them suggestions, which positively confirmed what Professor Tang said.

Jiang Jingan also pulled Jiang Zhi into the group.

However, the experiment naturally cannot be completed in one day, and Jiang Zhi does not have time to come here every day. After all, she does not have a dormitory at Peking University. The Jiang family villa is in the suburbs, and it is too troublesome to go back and forth every day. They can send the data to Jiang Zhi and let her verify it.

It was getting dark, and Jiang Jingan wanted to send Jiang Zhi home. It just so happened that he hadn't been home for some time, so he went back to stay for one night and come back tomorrow.

The others were a little reluctant to part with Jiang Zhi. She was a humanoid calculator with extremely fast calculation speed and high efficiency. How could a science student refuse her? They couldn't.

But they couldn’t force Jiang Zhi to stay, so as not to scare their future schoolmate, even though she wasn’t a direct relative.

Jiang Jingan saw her off and suddenly thought of something: "By the way, Xiaozhi, if you have nothing to do these few days, spend more time with your mother, take her out for some shopping or something."

"What's wrong?" Jiang Zhi was a little confused as to why Jiang Jing'an suddenly said that. After all, in many cases, she would only go when Xu Lanru asked her to go. Why did Jiang Jing'an seem to have something else to say now?

"Mom has been in a bad mood lately." Jiang Jingan explained.

"Huh?" Jiang Zhi was a little confused. She came back yesterday, and although she didn't stay downstairs for a long time, she really didn't notice that there was anything wrong with Xu Lanru, or that she didn't look unhappy at all.

It’s not Jiang Zhi’s fault. Although Xu Lanru has encountered some unpleasant things recently, she is really happy that Jiang Zhi is back. She also doesn’t want to show it in front of Jiang Zhi for fear that Jiang Zhi will worry.

So Jiang Zhi didn't notice anything abnormal about Xu Lanru at all.

Jiang Jingan was silent for a while, but after a while he started talking again: "Xiao Zhi, my family has never told you about my family's affairs. In fact, I don't think it's necessary."

Xu Lanru and Ning Chengyuan have known each other for a long time, and their homes were not far from each other before.

Both of them came from grassroots backgrounds, but compared with Xu Lanru, Ning Chengyuan was more independent-minded. Therefore, Ning Chengyuan started a business with Shen Hao during college, and then the two of them got together after they understood each other's feelings.

However, Xu Lanru did not know much about business matters, and it was only later that she met Jiang Shichang, a man worthy of her lifelong trust.

However, although they came from grassroots backgrounds, their lives were completely different. Ning Chengyuan was the only daughter in the family. Her family had given all the love to Ning Chengyuan since she was a child, so she grew up in a loving family.

Later, she and Shen Hao started a business together, and after they got married, their family always supported them.

Although the living conditions of both sets of parents improved a lot after they succeeded in starting their own business, Ning Chengyuan's parents had no money before and had to work hard. Over the years, they have suffered from many major and minor illnesses.

Not many years later, they died one after another.

Therefore, Ning Chengyuan lived a pretty good life.

But Xu Lanru is different. She is the eldest child in the family and has a younger sister and a younger brother.

If it were just this, it wouldn't be a big deal, but she has never been favored by her family.

This didn't happen even before my younger siblings were born.

Their family is not the traditional one that favors boys over girls. They just don't like Xu Lanru. After all, they like their little daughter very much too.

In fact, when she was a child, Xu Lanru's family conditions were better than Ning Chengyuan's, but their lives were completely different.

Xu Lanru's parents never gave her any love. She had to do all the housework and was the one who got scolded every time. Her treatment was even similar to that of Jiang Zhi in the Jiang family before.

My younger brothers and sisters at home really live a refined and happy life.

Xu Lanru grew up in such an environment, but she was the best and most hardworking student in the family.

But her family seemed to be unable to bear the fact that she was better than her younger siblings, and for a period of time they either beat or scolded her.

At that time, Xu Lanru understood this deeply, so she deliberately did poorly in the next exam.

Although she was severely beaten by her parents after this incident, they also said that she had cheated to get such good results in the previous exams, and asked her why she had to cheat when there were so many other things she could do.

But the days after that were much better. She would only be mocked by them from time to time, but that was nothing to Xu Lanru. She had already gotten used to it anyway. As long as they didn't beat her, it was fine.

However, hiding like this won't bring you peace forever.

Xu Lanru was going to high school, but because she hid her abilities, she only got into an ordinary high school.

But her parents were unwilling to let her continue her studies, so Xu Lanru fled from home. One of her previous teachers knew her family situation and always felt sorry for her.

Because she was middle-aged, her husband died of illness early in his life, and she never remarried and had no children. She felt sorry for the little girl Xu Lanru and always treated her like half a child.

She also knew that Xu Lanru had been hiding her strength, so she had been helping her study and told Xu Lanru to come to her for help if she had any problems.

Xu Lanru was desperate at this moment, so she thought of this teacher. Although this was not a good idea as it would trouble the teacher too much, and would also bring her family's troubles to the teacher.

But at that time, Xu Lanru didn't have as many skills as Jiang Zhi, and she didn't know how to make money.

She had no choice, but she wanted to study, because only studying could change her current situation.

So she went to find the teacher.

The teacher looked at the girl in front of him and decided to accept her.

I also used some connections to get Xu Lanru into a better high school.

At first, Xu Lanru's parents looked for her everywhere for a while.
