Jiang Nian understood everything as soon as he heard it. These students who graduated from Capital University were all outstanding and arrogant. They would not get angry if the professor scolded them normally, but being treated like trash would hit their proud hearts, and they would feel uncomfortable when being scolded.

That's why Han Mei and others think Lu Xianying is particularly vicious.

After all, even a smart person will feel inferior in front of a genius.

Jiang Nian did not bother Han Mei any more. She just asked Han Mei to point the way. She took Jiang Rendong and knocked on the door of an office.

"Professor Lu, someone is looking for—"

Han Mei plucked up the courage to speak, and without waiting for Lu Xianying to answer, she turned around and ran, not wanting to glance at Jiang Nian.

She felt in her heart that Jiang Nian would definitely be scolded.

There was a layer of scattered papers in front of Lu Xianying, with tons of numbers and curves on them. He had a pen in his hand, writing something non-stop. When he heard the voice, he frowned unhappily, but did not raise his head to speak.

"I told you, no one is allowed to disturb me while I'm calculating."

Jiang Nian spoke slowly, "Uncle Lu, it's me."

Lu Xianying stopped writing with the pen in his hand.

No matter who he forgets, he will never forget Jiang Nian's voice, nor will he forget the mystery surrounding Jiang Nian.

Lu Xianying put the work in his hand aside, looked up at Jiang Nian, took off the glasses he had worn for a day and a night, rubbed his sore brows, and asked, "Why are you here?"

"I brought my brother here." Jiang Nian explained, "His name is Jiang Rendong."

Lu Xianying put down his hand that was rubbing his brow, put on his glasses again, looked at Jiang Rendong carefully and said, "It's him. I remember that Sanye mentioned to me that he wanted me to take care of this child for a while, and then he would prepare to take the college entrance examination."

Qin Sanye made arrangements with Lu Xianying in advance, which saved Jiang Nian a lot of trouble.

She reminded Jiang Rendong, "Rendong, call Teacher Lu."

"Teacher Lu, hello." Jiang Rendong bowed respectfully to Lu Xianying, "I am Jiang Rendong, thank you for being willing to teach me."

Lu Xianying nodded calmly. He was usually very cold and it was impossible to tell from his expression what his attitude towards Jiang Rendong was, whether he hated or liked her.

But getting Lu Xianying to agree to accept him as a student was definitely not as simple as a few words from Qin Sanye. To use personal connections in the matter of studying is the greatest insult to intellectuals, and Lu Xianying is not the kind of person who would do that.

The reason why Lu Xianying agreed to accept Jiang Rendong as his student was that Qin Sanye provided some of Jiang Rendong's study notes. Jiang Rendong was a student who studied hard on his own in the mountains and yearned for the knowledge in books, seeking knowledge and learning.

This story sounds so familiar, isn't it Lu Xianying's own personal experience?

Lu Xianying saw his own shadow in Jiang Rendong. At that time, he could tell from his notes that Jiang Rendong had good qualifications, was a smart child, and had potential, so Lu Xianying was willing to train him.

However, the previous promise was a thing of the past, and the situation is different now.

"No, you don't have to call me teacher in a hurry." Lu Xianying stopped Jiang Rendong from becoming his disciple. At the same time, he looked at Jiang Nian and asked, "It's not difficult for you to teach a student who wants to take the college entrance examination. Why don't you teach him yourself?"

In Lu Xianying's eyes, Jiang Nian is a more powerful scientist than him, so he had this question.

Jiang Rendong looked at Jiang Nian in surprise when he heard this. He had a lot of questions in his head. Is Jiang Nian's knowledge level at this level now? Even Professor Lu affirms her?

But when Xiaoxiao was a child, Jiang Nianxiao failed several exams and threw the homework she didn't want to do to him in elementary school. She didn't want to study at all.

If this wasn't his biological sister, Jiang Rending would have wanted to expose her past.
