After solving this math problem, the answer is a long string of numbers, 11 digits, like a phone number. Zhang Ning found the mouse from the pile of paper, opened the computer's mailbox, but put down the mouse again, and watched the computer screen go black a little bit.

The phone next to her suddenly vibrate, and when she looked at the caller ID, she picked it up and swiped it. A voice came from there, "Did you solve it?" This is directly a math problem in college, are you ready to go to university? ”

"It's out, thank you sister-in-law for me." Such a complex and difficult problem is solved with an 11-digit number. She looked at the numbers and gradually deepened her impression.

The boy laughed, "Well, I will." Is your brother great, or is your sister-in-law great? Before he could answer, he heard a "beep" sound in his ears.

Zhang Yanyuan, who was outside the library, looked at the mobile phone with the screen off, and then looked at the girl who was laughing and moaning on the side, pretending to be weak and put his head on her shoulder, "Ask for comfort, the handsome guy who was saddened by his sister." ”

"Your sister is very powerful, and she understands it as soon as she says it. Maybe it was the smart boy who gave her the question. The girl rubbed his hair and nudged him to stand up straight.

Zhang Yanyuan thought for a while and said, "Who knows? But she's not a love brain, so I'm relieved that she won't be deceived and messed around. ”

"Do you know what that question looks like? It will involve the knowledge of college mathematics. Zhang Yanyuan held the book, and while going up, he looked at the girl next to him and asked.

"I don't know about this, she only asked questions about knowledge answers, told her, and then said, I understand, trouble you, thank you, sister-in-law." Speaking of the back, she covered her mouth and looked at Zhang Yanyuan and smiled.

Zhang Yanyuan smiled and took her hand and walked into the library.

In the hospital, a girl leans on crutches against a wall and practices walking over and over again. She looked at her legs and felt lucky.

Wei Liqiu walked in with a lunch box and saw her, "Yo, didn't you just finish your rehabilitation at this time, don't you take a break?" ”

"Brother Wei, are you here?" Lan Yu walked over slowly, sat down at the small table, his eyes full of brilliance, and looked at Wei Liqiu. Seeing the hearing aids in his ears, his eyes darkened a little.

"I'm not coming, is that okay? Wipe your hands and eat. Wei Liqiu set up the meal, opened the bag of wet wipes and handed it to her.

"Thank you, Brother Wei, Brother Wei has worked hard. This dish is so hearty! Cook so many meals for me. Blue Eucalyptus lowered her head and smelled.

"You think too much, order takeout." Wei Liqiu looked down at his phone and said.

"Then thank you for saving my life and taking care of me in the hospital every day." Lan Yu gently stirred the soup with a soup spoon and looked at him gratefully.

"Eat quickly, I've been there for you at the sanatorium, and there's nothing wrong with your sister. I hope she wakes up soon. Wei Liqiu didn't understand why she said that she wanted to commit suicide, this reason was too far-fetched, and asked not to pursue it further. looked at her and asked, "You are twenty-two this year, are you still studying?" ”

"yes, I'm just a few years younger than you. I was guaranteed to go to college when I was a sophomore in high school. ”

"I'm in my thirties, and for you, you're really young."

"Do you have a girlfriend then?"

"Yes, after graduating from high school, I have been in a long-distance relationship for five years, and there are more people who get together less and leave more. She said that she didn't pursue love anymore, but wanted to pursue a higher quality of life, so she didn't conspire with each other, broke up, and she got married last year. ”

"So you've been single until now? Is it because of her. ”

"You think this is a movie novel, life is reality, and time will dilute the feelings in your heart. Don't talk about it, talking too much will have an impact on your young people. With that, he got up and walked out with another lunch box.
