The aloof military doctor arrives at the unit, and the tough guy can't sit still.

The woman the Lu family introduced to Lu Zhenghan is so outstanding. If she continues to pester him now, who knows if Lu Zhenghan will regret it later? It's better for them to calm down and wait until Lu Zhenghan really thinks things through before making a decision.

Xia Qiuran sat on the steps outside the water room and finished eating the rest of her breakfast. After washing her lunchbox, she went to the first class to join in the drills.

After running 3 kilometers, she could take a short rest. Xia Qiuran sat under a tree and patted her calves. Before, she would be out of breath after running such a long distance, but after so many days of training, she could handle it completely. It seems that training more often in the morning and evening has its benefits.

"Look, the commander seems to be looking this way," someone suddenly said.

Xia Qiuran subconsciously turned her head to look, but quickly looked in another direction.

After what happened last time, Wei Guangming and Xu Yong were completely traumatized. They couldn't help but straighten their backs and behave themselves properly when they heard the word "regiment commander".

Bai Yunyun immediately tidied her hair. Lu Zhenghan might be looking at her right now, so she couldn't afford to look bad.

"Have you heard? Our regimental commander is getting married soon, and his bride is a talented person who has returned from studying abroad," a soldier suddenly said casually.

Before anyone else could react, Bai Yunyun was the first to explode, immediately snapping at the soldier who had just spoken.

"What nonsense are you talking about? Spreading rumors about the regimental commander will get you punished."

The soldier, not to be outdone, immediately explained, "How is this a rumor? I heard it with my own ears when I went to the political commissar's office to deliver something. That female comrade can even solve professional problems that the regimental commander's father couldn't. Our country is in dire need of such talent right now. She said that as long as she marries the regimental commander, she will stay in the country and never leave again. So, both for the sake of the public and for the private, the regimental commander will marry her."

Xia Qiuran listened silently to the soldier's explanation. It turned out that Nie Ru was even more formidable than she had imagined, and their union even involved national interests.

No wonder Lu Zhenghan's father did so many things to her before. If a marriage can save the country so much trouble, this deal is indeed worthwhile.

"What? Using a lifetime of marriage to keep someone? What would that make the commander? A tool? The commander would never agree to such a thing," Bai Yunyun said firmly, her face ashen.

Xu Yong realized that Bai Yunyun was angry because she liked Lu Zhenghan, and a surge of jealousy welled up inside him. He continued.

"I don't think so. She's a top talent in the industry. Marrying a wife like that would make the whole country envious. The regimental commander is a man too, and he naturally has vanity. Even if he disagrees at first, he'll eventually agree."

These words seemed to strike a nerve with Bai Yunyun. His family background, which he had always been proud of, seemed to have become worthless in front of this woman.

She thought for a long time but couldn't come up with a powerful rebuttal, because deep down she also agreed with the statement: how could a man not love a woman who is top-notch in everything?

"What do you know? The commander doesn't care about these things, and he certainly doesn't like those rigid and boring researchers."

He gritted his teeth, glared at Xu Yong, and then fell silent.

Xia Qiuran's mood was even lower than before. If her relationship with Lu Zhenghan could be considered a small love affair, then Nie Ru's relationship with Lu Zhenghan could be considered a love for her country.

Wouldn't it be too selfish for her to stay by Lu Zhenghan's side?

Sigh, I never expected that a relationship would cause so much trouble. Fortunately, it hasn't been long, so even if we break up, it won't be too painful.

However, after spending several days together, Xia Qiuran's mood wasn't too good that day. When she arrived at the night school training class that evening, she secretly breathed a sigh of relief upon hearing that Bai Ganshi had returned from leave. If she were to meet Lu Zhenghan now, she really wouldn't know what to say.

Bai Ganshi took over Lu Zhenghan's Chinese and Math classes, and today happened to be both Chinese and Math classes, with no English.

In math class, Bai Ganshi stood there, speaking with great enthusiasm. His teaching style was very different from Lu Zhenghan's. Lu Zhenghan was a typical gifted student. No matter what the problem was, he could always find the simplest and easiest way to solve it.

Bai Ganshi, on the other hand, only explained things according to the book, and spoke with a heavy accent. Even though Xia Qiuran concentrated her attention during the lecture, there were still some parts that she did not understand.

After class, he went to ask the classmate at the next table.

"Xiao Li, do you know how to do this problem?" Xia Qiuran asked humbly, holding her notebook.

"You can't even answer this question!" Xiao Li glanced at it, slightly raised his chin, and his eyes were full of confidence.

"Yes, I didn't quite understand. Could you explain it to me?" Xia Qiuran thought she had asked the right person and quickly replied.

To everyone's surprise, Xiao Li said something in the next second.

"I don't know either. Bai Ganshi's accent is too heavy. It sounds like a foreign language to me. How could I possibly solve the problem?"

Xia Qiuran silently put away her notebook, her eyes filled with hatred for Xiao Li. Why did she have to act so confident, making her happy for nothing?

Just as I turned to ask the other classmates, I discovered that the notebook in my arms had been taken away first.

"That's my book."

Xia Qiuran was a little angry. She already had enough of a troublesome day, and she wasn't in the mood to joke with anyone.

But when she looked up, she found Lu Zhenghan standing in front of her, looking at the question.

There's no English class today, so why is he here?

"Let's solve this problem like this first."

Lu Zhenghan's mood didn't change much. He put the notebook on the lectern and began to explain to Xia Qiuran.

His gaze was focused and calm, as if he had shut out the surrounding noise.

His fingers held the pencil, the knuckles were distinct, and his nails were neatly trimmed. Due to years of training, there were also some rough calluses on his fingertips.

Xia Qiuran stared at his fingers, somewhat lost in thought.

"Read the questions carefully."

Noticing that Xia Qiuran was not concentrating, Lu Zhenghan pointed at the notebook with his finger and said.

Xia Qiuran then came to her senses and quickly looked at the exercises.

"This problem is mainly about the approach; once you get the approach right, the difficulty will be easily solved."

Lu Zhenghan quickly wrote down the solution steps in his notebook. He wrote down two methods: one was the one in the book, which had many steps and was quite complicated; the other was the one he wrote himself, which was much simpler and only took two steps to calculate the result. However, Xia Qiuran didn't quite understand how he calculated it.

"But why is it number 2 here? I still don't quite understand," Xia Qiuran asked, pointing to the steps Lu Zhenghan had written down.

Lu Zhenghan paused for a moment, glanced at the time again, and then spoke.

"Class time is over. I'll continue the lesson after class."

Attend class?
