I studied abroad in modern times

After the monthly exam results came out, Zheng Fa and Tang Lingwu came to Old Man Bai's house again.

"I heard that you did well in the exam this time?" Old Man Bai asked Zheng Fa.

The expression on his face was not so much a compliment as a faint pride.

"That's because you taught me well." Zheng Fa said politely.

Upon hearing this, Old Man Bai's face wrinkled into a brilliant chrysanthemum.

"I have a friend who also has some difficulty in studying..." Zheng Fa suddenly said while he was in a good mood.

"Stop it!" Old Man Bai raised his hands and frowned slightly: "I refuse."

Zheng Fa didn't expect the old man to be so vigilant and refused directly without even saying a word.

He was not in a hurry, he just glanced at Old Man Bai, said nothing, and just waited.

Sure enough, seeing that he didn't say anything, Old Man Bai himself felt itchy: "You really don't want to say anything?"

Zheng Fa looked at the old man with confusion: "Don't you always ask me to stop?"

"Why don't you beg again?"

Zheng Fa spoke as he wished: "Do you have the simplest and quickest solution to those talismans?"

"How else can it be done quickly?"

Zheng Fa opened his mouth, not knowing what to say.

But Tang Lingwu understood it and gave an accurate translation: "Three long and one short choose the shortest, three short and one long choose the longest..."

Old Man Bai's face darkened: "No wonder you are not friends with me. I am a professor at Beijing University, and you want me to teach you how to cheat? You are insulting me with these crooked ways!"

Zheng Fa wanted this kind of question-obstructing technique because of a friend - the Seventh Young Master.

In two months, Young Master Seven will come to the immortal sect. It is absolutely too late for him to really start learning from "Primary School Mathematics". He can only rely on ignorance, no, rely on the great and magical probability science.

Even if it wasn't for the seventh young master, just because of his wife's request, Zheng Fa would still have to find another insurance policy for the seventh young master.

As expected, the old man Bai shook his head rapidly when he heard this request, and his small curly hair spread its teeth and claws in the air, telling the master's rejection.

Zheng Fa winked at Tang Lingwu.

Tang Lingwu understood the idea and assumed the posture of a pine and crane pile.

Zheng Fa put his hands behind her back.

Old man Bai looked on and asked curiously: "What are you two doing?"

"I thought of a quick fix." Zheng Fa said with a smile: "Let her practice faster."

"..." Old Man Bai blinked: "How fast?"

"According to my estimation, she will have no problem getting started in Songhezhuang in another half month." Zheng Fa thought for a while.

Old Man Bai's eyes widened slightly. He remembered that Zheng Fa had said before that Tang Lingwu was young and in good health, so she should be able to practice faster than him, but it would take at least two or three months for Songhe Zhuan to get started.

Now it only takes half a month?

"This..." Old Man Bai rubbed his hands and said, "Well, can I... try this method too."

"That's not okay. How can I insult you with evil ways?" Zheng Fa's refusal should be as sincere and sincere as possible.

"Actually...it's not like you can't insult and insult."

After Old Man Bai finished speaking, he looked at the unchanged smile on Zheng Fa's face, gritted his teeth, turned around and entered the study. When he came out, he held a black-covered notebook in his hand.

"This is?"

"I don't know that kind of thing, and I can't teach it to you, but you can still learn it faster." Old Man Bai handed the notebook to Zheng Fa with a straight face.

Zheng Fa flipped through his notebook.

What is written in it are some rules that Old Man Bai has summarized through those runes - not the general rules, but through the characteristic patterns of each rune to determine which basic elemental rune this rune probably evolved from. .

"Except for some very complex patterns, these methods are guaranteed to be 80% or 90% accurate."

Zheng Fa nodded. This notebook is not thin. Old Man Bai wrote it very carefully. What kind of characteristic pattern does each elemental symbol correspond to? Then there are about ten symbols for each characteristic pattern as examples.

Probably because he was a bit slow in learning topology, Old Man Bai simply skipped the principles and went directly to the application.

"Is this what you are doing?" Thinking that this was what Old Man Bai took out from the study, "Have you been prepared?"

"I'm not writing a book out of boredom, just summarizing casually." Old Man Bai coughed dryly, his eyes wandering.

Zheng Fa knew that the old man must have put in a lot of effort, and he couldn't help but show some emotion on his face.

"Don't be so pretentious." Old Man Bai said uncomfortably, and continued: "I see that your kid attaches great importance to these things and is very anxious."

Zheng Fa was silent, he was indeed a little anxious, not only for the seventh young master, but also because he wanted to use Fu Dao to escape from the Zhao family.

"Remember, this is just a trail." Old Man Bai warned again.

Zheng Fa took the notebook, looked at Old Man Bai seriously, and bowed.

"I told you, don't be so pretentious." Old Man Bai waved his hands uncomfortably, then suddenly looked at Zheng Fa and added: "I told you, I didn't want to accept you in the first place."

"You always said that I am not a math student."

Old Man Bai pointed to the notebook in Zheng Fa's hand and said, "I actually planned to give this to you later, but since I gave it to you today, I have something to say to you."

Zheng Fa rarely saw such a serious expression on Old Man Bai's face.

"I don't want to accept you, actually because you don't look like her." Old Man Bai pointed at Tang Lingwu beside him.

"This little girl is simple-minded, but you are full of thoughts." Old Man Bai's eyes fell on Zheng Fa again: "You have two problems. If you act too hastily, you should be careful."

These words were not unimportant. Tang Lingwu on the side opened her mouth, as if she wanted to say a few words for Zheng Fa.

"I'm not criticizing this kid. With his life experience, it's normal for him to have complex thoughts." Old Man Bai stopped Tang Lingwu's words.

"But it's not academically good to do this. I told you last time about the issue of being too hasty." Old Man Bai continued to say to Zheng Fa who was silent; "Also, let's talk about self-preservation. Speaking of which, I really hope you are really begging me for a friend. ”

"You are a martial arts practitioner. It is believed in the world that whoever has the biggest fist is the boss. Everyone hides some magic secrets in their hands, wishing that only you could practice it."

Zheng Fa thought about the atmosphere in the Xuanwei world and nodded.

"But academics are different, Zheng Fa, remember." Old Man Bai stared at Zheng Fa and said; "Academically, our enemy is never anyone else, it is the mysteries of this world and those unresolved problems."

Zheng Fa somewhat understood what he meant.

"Why do I want to write a book?" Old Man Bai continued: "Because when I was studying mathematics, I read many other people's books. I know that without these books, I would not be able to achieve what I am today. I would be stepping on the footsteps of my predecessors. Shoulders are climbing mountains. When I get old, I also want to be a shoulder for future generations to step on. "

"I understand." Zheng Fa said to Old Man Bai.

He knew Old Man Bai's good intentions, but to be honest, at least in the Xuanwei world, he couldn't fulfill Old Man Bai's request, at least not now.

"No, you don't understand, do you know? In my eyes, those of us who are engaged in academics are just an alliance of losers - the world is vast and science has no end. Maybe tomorrow the truth we believe in will become a fallacy, and maybe mankind will never Unable to see the truth of the world, it can be said that our failure is inevitable." Old Man Bai shook his head and said, "So we must not only accept failure, but also stay together for warmth. There is a saying that may not be right elsewhere, but it is right for us. - If you want to go far, you have to go together.”

"I will keep your words in mind." Zheng Fa said solemnly.

He thought he couldn't do it, but that didn't stop him from thinking that what Old Man Bai said was right.

"No, you don't understand." Old Man Bai suddenly showed a naughty smile: "What I just said is all nonsense. The most important thing is - since we will all fail, then don't be bothered by the temporary success or failure. ”

Zheng Fa suddenly raised his head and looked at Old Man Bai: "How did you know that?"

He finally understood why Old Man Bai suddenly said these things - after meeting his wife, he felt a little confused, but Zheng Fa thought that he was good at hiding his emotions so that others could not see it.

Now he discovered that whether it was giving him the notebook or these words about losers, Old Man Bai was probably trying to comfort himself by making insinuations.

Old Man Bai curled his lips and pointed behind Zheng Fa: "This little girl told me quietly."

Zheng Fa turned around and saw Tang Lingwu standing behind him, holding milk tea and handing it to him. There was no expression on his face: "Here you drink."

He was silent for a moment, took the milk tea and took a sip. Then he stared into Tang Lingwu's eyes and said, "It's very sweet."

Old Man Bai muttered from behind: "I'll just say that it's troublesome to accept students, and you have to do a lot of hard work... I haven't mastered martial arts yet, it's a big loss!"

"Grandpa Bai...what you said before was a bit one-sided, wasn't it?" Tang Lingwu seemed to be a little confused about what Old Man Bai said before: "Aren't all academia beautiful? I read a lot of plagiarism and plagiarism news."

Both she and Zheng Fa understood that those words before were not really nonsense.

Even though the old man didn't want to accept it before, he doesn't want to accept it now, but from his teachings, they can also understand the old man's expectations for the two of them.

Hearing Tang Lingwu's question, Old Man Bai pointed at Zheng Fa with a puzzled expression: "Is this guy showing off his martial arts skills to look good?"

Zheng Fa translated Old Man Bai's words in his mind:

The scientific community is full of decent people.

But if someone doesn't want to look good, Zheng Fa can also help him look good.

…

When he woke up, he arrived in Xuanwei Realm again. Gao Yuan suddenly stared at Zheng Fa and said, "Zheng Fa, why do I feel that you are smiling a lot more this morning than you were two days ago?"

"I was a little unhappy the past two days, but today I decided to do something to make myself happy." Zheng Fa nodded.

"What's going on?" Gao Yuan asked curiously.

"You've been studying math for a while, so I think it's time to take a surprise test today to celebrate!"

Gao Yuan suddenly turned his head to look at Zheng Fa.

Seeing Zheng Fa's heartfelt smile, a question slowly appeared on his face: "Are you taking exams for fun?"

"No, I am making fun of you." Zheng Fa replied sincerely and impersonally.
