Chapter 421 Is it so sudden?
"Teacher, Madam, I'm sorry to bother you again." Su Yi came to the staff dormitory, and the two elders were already waiting there.
"You are so polite, kid." Zhang's mother chuckled, "Come in quickly. Your brother Sibo will be back with his girlfriend later. It's a good opportunity for us to have dinner together."
Su Yi smiled: "I have never met my sister-in-law before."
"Then we can see each other today."
As he was speaking, the door opened again: "Dad, Mom, I'm here with Linlin!"
Zhang Sibai's girlfriend is Fan Yalin, whom he met after work. They have been together for more than a year and their wedding date is also on the agenda, set for May Day this year.
"Sister Su Yi?" Zhang Sibai looked at her in surprise.
"Brother Sibai, sister-in-law." Su Yi greeted with a smile.
Fan Yalin heard about this "sister" from her boyfriend, the famous academic master Gu Suyi, who was almost treated as her own daughter by her future in-laws.
"Why did you come here suddenly today?" Zhang Sibai asked with a smile.
"After dinner, I'll go to school and register. From today on, I'll officially be studying for my doctorate under you."
"My dad will definitely be happy then."
There was a strange look in Fan Yalin's eyes. How old is this "sister-in-law"? She is already studying for a doctorate when she is not even 22 years old?
Sure enough, he is not an ordinary person.
Zhang Yuan then walked out of the study, adjusted his glasses, and smiled, "Linlin is here. Have you all met her?"
"Please sit down for a while. Dinner will be served in half an hour." Zhang's mother said hurriedly.
"Auntie, let me help you." Fan Yalin said quickly.
"No, no, just sit down and chat for a while. Your uncle will come and help you."
There were only three young people left in the living room.
Su Yi asked about the things between the two of them. When talking about the wedding, Su Yi said, "Brother Sibai, sister-in-law, please send me a copy of the invitation. Xiao Tingzi and I will come together when the time comes."
"No problem." Zhang Sibai agreed immediately, "Why didn't Xiao Tingzi come with you?"
"Shen Corporation is holding a shareholders' meeting recently, so he's busy. He'll come pick me up in a few days and then go back to the capital together."
"You'll be back in a few days?"
"Well, I'm quite busy with the project at the research institute, so I've only been reporting to University C these past few days."
Zhang Sibai asked with great interest, "I'm quite curious, what is your doctoral research topic?"
"The problem of P and NP is somewhat related to my doctoral thesis in computer science, so I chose this topic," said Su Yi.
Note: The P/NP problem involves the relationship between the complexity classes P and NP. In 1971, Stephen and Leonid Levin independently raised the question of whether the complexity classes P and NP are identical (P=NP?).
Although Zhang Sibai didn't follow in his father's footsteps and study mathematics, he was well-informed about some of the news in the mathematical world. He was a little surprised: "This is also the problem that the Clay Mathematics Institute included in the Millennium Prize, right? Are you planning to shake up the mathematical world again?"
Su Yi didn't know whether to laugh or cry: "Brother Sibai, it's not as exaggerated as you say."
"What's stirring up trouble?" Zhang Yuan just walked out.
"Dad, Su Yi said her doctoral thesis is about the P-NP problem. That's a difficult problem that's been included in the Millennium Prize! If it were solved, wouldn't the math world be blown away?"
"You're still concerned about this?" Zhang Yuan dismissed him. "We're out of soy sauce at home. Go buy a bottle at the supermarket and two bags of salt."
Fan Yalin stood up: "I'll go with you."
"No, it will be quick. Just talk to Su Yi."
It was also Fan Yalin's first time meeting Su Yi, and she felt a little embarrassed and didn't know what to say. What's more, the other party was not only a top student, but also the young lady of the Shen Group, and she happened to work in a company under the Shen Group.
Su Yi noticed her discomfort and took the initiative to talk about topics that interested her, slowly resolving the awkwardness between the two.
After lunch, Zhang Yuan took Su Yi to report.
All the professors in the Department of Mathematics at C University knew this little freak Su Yi. Some of them even asked her about her research topic out of curiosity, but Su Yi replied, "I haven't decided on it yet."
She is well aware that a big tree attracts the wind.
You should hide your shortcomings when it is time to do so.
However, before Shen Yanting came to pick her up, a hot search came out of nowhere and blew up the entertainment industry.
#Popular young actress You Xiawan announced her retirement from the entertainment industry and is suspected of getting married and having children#
When Su Yi saw this trending search, he was stunned.
Soon, Shen Yanting called her: "Baby, you have to go home, your sister-in-law is pregnant."
Su Yi: ???
Is it so sudden?
"I just received a call from my brother. He's bringing his wife home tonight to discuss their wedding. My parents are completely stunned. If you're free, can you come home today?"
"Okay, I'll tell the teacher and buy a flight back this afternoon."
Afterwards, Su Yi told Zhang Yuan about this, and Zhang Yuan was also very surprised. It can be seen that in everyone's mind, Shen Yanxiu is a non-marriageist, but no one expected that he would drop such a bomb quietly.
