She could easily tell whether Old Man Xu was lying or genuinely couldn't remember.

For example, just now, Old Man Xu didn't tell the truth.

But it's true that Feifei doesn't know what her parents do for a living.

It seems that Xu Honglin and his wife's work is truly extraordinary; they must be engaged in top-level state secrets.

Gu Zhiyun seemed to have guessed something. He quietly took Shen Jingyan's hand and wrote a word on her palm.

It is the character "核" (hé).

Calm and collected, I understood immediately. Anything related to this word must be an absolutely confidential project.

The saying "like father, like son" is absolutely true. Old Xu himself is a scientific research leader, and his son and daughter-in-law are also outstanding figures in the scientific research field.

Shen Jingyan never imagined that she would have the opportunity to get up close and personal with so many top figures in the scientific research community in her lifetime.

In the past, these important figures were only seen in photos in history textbooks.

After chatting for a while, Old Xu started complaining that he was hungry.

"Mom and Dad won't be back for lunch today. Grandpa, what would you like to eat? I'll make it for you."

Although Feifei looks like a delicate little princess, she is quick and efficient in everything she does.

Old Xu stared longingly at Shen Jingyan.

She smiled and said calmly, "I brought a lot of local specialties from Northeast China today, so I'll cook a delicious meal for Grandpa."

Old Xu nodded with a broad smile: "Yes, yes, yes, I'm really craving your cooking."

"Then I'll assist Sister Jingya!"

Feifei also rolled up her sleeves.

Despite her young age, the girl is quick and efficient at her work, and she is very skilled at washing and chopping vegetables.

Shen Jingyan couldn't help but sigh. Despite living in such a well-off family, the little girl hadn't picked up any princess syndrome and had a very likable personality. Compared to Zhao Yanyan, they were worlds apart.

This is undoubtedly inseparable from the strict family education of Xu Honglin and his wife.

Shen Jingyan steamed rice for five people. Feifei looked at the pot and said, "Sister Jingya, put in more rice. My sister is home too, so there are six of us in total."

Shen Jingyan was taken aback: "You have an older sister?"

Feifei nodded, glanced at the kitchen door, and whispered to Shen Jingyan, "Yes, she and I are half-sisters. Dad divorced his ex-wife before marrying Mom. Ten years ago, my sister's mother abandoned her and went to the United States, so she has been living with us ever since."
