I studied abroad in modern times

Zheng Fa could never have guessed that his wife could reasonably and outrageously infer that there was a Yuanying Zhenren behind him from the fact that he had mastered the "Spirit Crane Body".

His problem now was that the old man behind him, Old Man Bai, was tired of studying.

No, he wanted to drop out of school.

One night, after tutoring Tang Lingwu, he suddenly said to Zheng Fa: "Xiao Zheng, I probably won't have time to practice martial arts in the future."

Old Man Bai's progress in martial arts was too slow, and he couldn't see any results, so his enthusiasm naturally faded day by day.

Zheng Fa had always seen it and had expected this day.

Looking at Old Man Bai, Tang Lingwu couldn't help but doubt: "Grandpa Bai, you want to give up because practicing martial arts is too tiring and painful, right?"

"What do you mean by giving up?" Old Man Bai said confidently: "I have other important things to do, and I can't spare time! You are busy, don't you understand?"

"What can you do as a retired person?" Tang Lingwu obviously didn't believe it.

"Don't disbelieve me!" The old man raised his head and said, "Someone from Beijing University Press called me a few days ago and said they were waiting for my new book!"

When he said this, Zheng Fa and others were a little surprised.

"You are still writing books, I haven't heard you say that before?"

"Can I brag to you two young people?" The old man tilted his mouth: "I said I'm retired and I'm old and useless, but people are crying and shouting for me to write a book!"

He boasted like this, Tang Lingwu was a little suspicious: "What book are you writing?"

Hearing this, the old man sighed: "You don't know, some of our university textbooks were written in the last century, it's not that they are bad, they were all written by great scholars. But now everyone finds that, eh? It seems that they can be written better, and some new knowledge has not been updated."

"So what you wrote is the textbook of Beijing University?"

Tang Lingwu's tone was a little awed.

"One book, just one book." The old man waved his hand, very modestly: "It's not an important book, it's just that people are rushing me, I really don't have time!"

Seeing that he didn't seem to be bragging, Zheng Fa also looked at the old man with a new look in his heart.

"So, it's not that I gave up practicing martial arts, it's really that I don't have time." The old man explained again, "When I think of those students who are still learning those outdated textbooks, they are crying for food, I am so anxious! I can't sleep well!"

Hearing this, Tang Lingwu glanced at Zheng Fa, a little worried.

Sure enough, the old man continued to say to Zheng Fa: "Xiao Zheng, if you have any questions in the future, come to my house on weekends, I will spend one or two hours on weekends to explain it to you. As for topology and so on, you don't need it for the time being, and it's not impossible to learn it after the college entrance examination."

Tang Lingwu opened her mouth and wanted to say something, but she didn't know how to say it.

Zheng Fa nodded, but he didn't blame the old man in his heart.

Zheng Fa really enjoyed the private tutoring of Old Man Bai for a while. Although he had not yet started college mathematics such as topology, he was confident that he had a lot more understanding of the knowledge points of those college entrance examination mathematics.

As for Old Man Bai... He had been practicing "Songhe Zhuang" for a while, but he really didn't practice anything.

In a word, he still took advantage.

As for Old Man Bai's current transformation, on the one hand, it must be that learning martial arts did not give him enough positive feedback.

On the other hand, Zheng Fa was indeed learning slowly.

The disciple chooses the master, and the master also chooses the disciple, and this trend is even worse in the Xuanwei world.

After all, Old Man Bai taught the proud children of Beijing University, and it was natural for him to be a little disgusted with Zheng Fa's learning progress.

And he was not without good intentions. In his opinion, Zheng Fa's main task now was the college entrance examination, and he should not learn topology from him.

Zheng Fa was actually a little grateful in his heart: Old Man Bai asked him to come to his house for advice on weekends, which was actually very considerate. After all, he had nothing to ask of Zheng Fa now.

Seeing him nod as usual, Tang Lingwu exhaled lightly, and then, as if she had discovered something, she stared at Zheng Fa's face, with a very puzzled look.

"Why are you looking at Zheng Fa?" Seeing her staring at him, the old man suddenly got angry and said with a fierce face.

"He... seems to have changed?"

The old man narrowed his eyes and looked Zheng Fa up and down, but he didn't seem to see anything: "Nothing has changed, just one nose and two eyes."

"You are presbyopic, of course you can't see clearly." Tang Lingwu ignored him and stared at Zheng Fa's face: "Zheng Fa, what skin care products have you used recently?"

Zheng Fa knew that this was because Tang Lingwu discovered the changes in himself after practicing "Spirit Crane Body".

"I have made some progress in martial arts recently."

He explained to Tang Lingwu.

"Martial arts!" Tang Lingwu opened her mouth, as if she didn't expect Zheng Fa to give her such an answer.

"What's wrong?"

"I thought..." Tang Lingwu glanced at the old man Bai who was looking for his reading glasses: "You were fooling Grandpa Bai before."

The old man Bai put on his reading glasses and came to Zheng Fa, observing him carefully, as if he was doing some research.

"Can you see the change?" Tang Lingwu asked.

"No!" The old man Bai replied.

"Then you watch for a long time."

"I don't know what he looked like before, how can I see any change?" The old man Bai said confidently: "I'm not like a little girl like you, staring at a little boy every day!"

"..."

"So, you mean, you practiced a martial art, and then your skin got better?"

Tang Lingwu asked Zheng Fa curiously, as if she didn't hear what the old man said.

"Yes, one morning when I woke up, the whole person seemed to have shed a layer of skin."

"Then the longevity you said before is also true?" Tang Lingwu's eyes were brighter than ever.

"Of course it's true, do you think I'm lying to you?" Zheng Fa asked her back, and turned to look at the old man next to him: "You also think I'm lying to you?"

The two nodded in unison.

"Then what do you still practice?"

"It's not... I'm bored after retirement, so I practice for fun."

The old man smiled awkwardly.

"It's amazing..." Tang Lingwu stretched out her finger, as if she wanted to poke Zheng Fa's face, and stopped again.

"No, this is the image of me in your mind?"

Zheng Fa was a little depressed.

Were these two people playing house with him before?

"Isn't it because there are too many scammers on short videos?"

The two smiled at Zheng Fa a little embarrassedly.

"Do you believe it now?"

"I believe it, I believe it!" The old man and the other man nodded frantically, staring at Zheng Fa's face.

After a while, the old man's face suddenly became awkward: "Xiao Zheng... I want to learn martial arts again."

"Want to learn again?"

"Yes!"

"Aren't you very busy?"

"What are you busy with? I'm not busy! Who cares about you, a retired old man?"

"Aren't you going to write a book?"

"It's okay if you write slowly."

Zheng Fa shook his head slowly: "That won't work. Your students are crying for food every day."

"Let them cry, they won't starve to death!" The old man didn't care at all: "Who am I? I'm not a great mathematician. Do you really think I'm a dish? My book is so hard that it's hard to wipe my butt. It's not important, not important."

Zheng Fa didn't even look at his flattering old face, and turned to look at Tang Lingwu.

Tang Lingwu pushed the unopened milk tea in front of Zheng Fa with one finger.

"?"

"I want to learn too." There was a kind of enthusiasm in Tang Lingwu's eyes that was rare in her: "I'll buy you milk tea in the future."
