"Sister, I don't know much about this problem."

When Ning Ruixing was stunned, she spoke.

Xu Jiawen and the others asked, Ning Ruixing was worried that no one would ask, but who knew that one came. He immediately stepped forward happily and asked in a gentle voice, "Where, let me see."

The girl looked so quiet that she unconsciously softened her voice, afraid that she would scare her.

Ning Ruixing took the test paper and the first thing he saw was grade and junior high school.

She was a little surprised. She didn't expect that the little girl who looked like she had already been in the third grade of junior high school, and then she felt a little relieved. She was a college student, and the problem of the third grade of junior high school would not seem too difficult, right?

Ning Ruixing thought with some uncertainty.

The next second, she felt like she was slapped in the face again.

Physics in the third year of junior high school.

She was very serious when she was in junior high school. From the first semester of high school to the liberal arts and science, to the exam, she hadn't touched this thing in almost three years.

I had previously vowed that I would never want to see physics again, but I still couldn't get rid of the fear of being dominated by physics when I went to college.

Seeing the girl blinking her eyes and looking forward to her, Ning Ruixing couldn't say anything she refused, and carefully read the requirements of the question.

"The simplified circuit diagram of a hair dryer is shown in the figure. r1 and r2 are heating resistance wires and m is a motor.

After the switch s1 is closed, when s2 is connected to 1 and 2, the cold air blows, and the current through the motor is o.

When 1a, s2 is connected to 2 and 3, the resistance value of r1 is 110Ω..."

Ning Ruixing felt that she couldn't stand it anymore.

She patiently read the question several times, but still had no clue and was full of her mind to cycle through physical formulas.

She still remembers the formula clearly, but she just won't apply it.

God knows why she, a liberal arts student, suffers this kind of crime?

"elder sister?"

The girl spoke tentatively.

Ning Ruixing was really embarrassed by this topic, and his expression changed from relaxed to very seriousness. He sighed and walked quickly to Jiang Yu and touched his arm.

"Jiangyu, do you know this question?"

He is a science student and studies finance and economics. Such a question should be no problem, right?

Hearing Ning Ruixing's voice, Jiang Yu's eyes fell on her face. Seeing her heavy face, she couldn't help but feel a little funny and laughed softly, "What's wrong?"

If he hadn't been concerned about too many children, he would have pulled people into his arms and coaxed them.

Ning Ruixing repeated his words again, and at the end he felt a little aggrieved, "I don't know how to do this question, it's this..."

Jiang Yu took the test paper, just glanced at the question, and looked at Ning Ruixing with a smile, "You can't?"

Ning Ruixing sniffed, and continued, "I hate physics the most."

"I'll teach you."

Jiang Yu's voice was gentle and he was doting with a hint of love that he had only for Ning Ruixing. After taking the pen on the table, he had to analyze the questions and calculation process for Ning Ruixing.

When she was annoyed by physics, what she most hoped was that someone could answer her questions when she couldn't.

I never thought I didn’t meet in high school, but in college.

As if she was crazy, Ning Ruixing was about to speak up and respond, but before she could even speak her lips, she suddenly realized, "It's not me," she pulled Jiang Yu's arm, pulled him to the girl's side, and said to Jiang Yu, "You tell her."

Then, he leaned over and said softly to the girl, "Sister can't do this question, either, let me teach you, can you please?"

Because of the words in her words, Jiang Yu's eyebrows moved and a little smile appeared.

It was very indirect, Ning Ruixing called him brother.

After looking at Jiang Yu, the girl couldn't help feeling embarrassed, but she nodded and replied.

Ning Ruixing breathed a sigh of relief and wanted to give way to Jiang Yu. When he raised his eyes, he saw Jiang Yu looking at him with concentration, his eyebrows and eyes relaxed, and he was extremely gentle.

Several little boys and girls who had finished their homework ran out and were playing outside. The noise was a bit loud, and the sound of coaxing came in waves.

Ning Ruixing frowned, a little worried.

Lai Yin had just finished explaining the problem and had time to go out to take care of it.

Jiang Yu raised his hand uncontrollably and pulled her cheek, "Go outside and play with them."

Ning Ruixing glared at him angrily because of Jiang Yu's actions, and fell into Jiang Yu's eyes, but it was interpreted as a shy rebuke.

The girls who had been following Jiangyu were surprised to see this slightly intimate action.

Not many people sit here to do homework, and community tutors always last for two hours. They usually go out to play or leave first after finishing their homework. Now it is almost time.

Ning Ruixing nodded. When Lai Yin was outside, she probably couldn't bear to see so many people, not to mention that the task not only required checking their homework, but also having to play with them.

Just as she was about to step out of the door, she heard the girl's crisp voice coming from behind, full of curiosity, "Brother, are you in love with that sister?"

Ning Ruixing's heart was beating and he couldn't help but look back at Jiang Yu.

Who knew that he met Jiang Yu's gaze directly.

The thin lips gradually became obvious, and the meaning in her eyes was filled with her inability to see clearly.

"yes."

He generously answered.

After a word, Ning Ruixing's ears were inexplicably hot, and he hurriedly walked out quickly.

It was not until the fleeing back could no longer be seen that Jiang Yu slowly withdrew his gaze and lowered his head to answer the physics questions.

His statement was straightforward and clear, but in just a few seconds he explained the physics question clearly.

Someone packed his schoolbags one after another. Jiang Yu got up and walked outside, and saw Ning Ruixing having fun with a group of children.

A boy who was about eight or nine years old looked at him and held her thighs without letting go. From time to time, he rubbed his face with his little face.

Jiang Yu frowned slightly, and he didn't like him wherever he saw it.

Before he could walk to Ning Ruixing, the boy raised his head and asked, "Sister, do you have a boyfriend? Will I marry you when I grow up?"

Ning Ruixing once again expressed the feeling that the current children are really precocious.

Before she could answer, a clear and inexplicably cold male voice inserted in, and answered instead of her, "No."

Ning Ruixing followed the sound and saw Jiang Yu's tense jaw at a glance. Jiang Yu didn't look at her and looked at the little boy who only reached his waist. "Little boy, she is still a child herself and can't marry you."

"When I grow up and my sister grows up to be an older friend..." The little boy's thoughts turned quickly and he immediately replied.

"Ha," Jiang Yu chuckled, "When she grows up to be an older friend, she should marry me."

"Jiangyu!"

"Because," Jiang Yu turned a blind eye to Ning Ruixing's humiliating and annoyed shout, and continued.
