I studied abroad in modern times

In the lobby of the Zheng family, Zheng Fa looked at the calm and indifferent girl in front of him, and her unique hobby still echoed in his heart for a long time.

The last time Zheng Fa heard someone talk about solving math problems to relieve boredom was before a holiday in modern times. The math teacher walked into the classroom with a half-person-high test paper and said something like:

If you are tired of memorizing words during the holiday, you can do a set of math tests to relieve boredom.

He was sure that no classmate understood the logic of this sentence at that time, or, they were all asking logically in their hearts: If I want to relieve boredom, would I be so depressed as to do math problems?

But at this time, in another world, Zheng Fa found the soul mate of the math teacher!

He couldn't help but ask the doubts from the bottom of his soul: "Where is the joy of doing math problems?"

The blue-clothed woman raised her eyes, as if she had never thought about this question. After a while, she said: "Maybe, because it is a little difficult?"

"As long as there is something difficult, you will be happy?"

"There are not many difficult things in this world, right?"

Looking at the other party's sincere face, Zheng Fa had nothing to say, and could only give the other party a smile that was twisted with envy.

The woman in green raised her right hand. There was a white jade bracelet on her right hand. A bright light flowed on the surface of the jade bracelet, and then a scroll the length of a forearm appeared in the woman's hand.

Storage magic weapon?

Zheng Fa thought of the blue phoenix that covered the sky and the sun before, and guessed in his heart that this person should be the companion of the eldest lady - as for why it was not the eldest lady, if it was not for the slander of the seventh young master, then the eldest lady's hobby should not be mathematics, but stick skills.

"Is this book also used to test your talent for talismans?" The woman pointed to "Junior High School Mathematics" and said: "Many talisman masters like to test their disciples' mathematical talents first. Although I have never seen this book, my master also threw me a math book back then, and only accepted me as a disciple after I solved all the problems on it."

... Someone plagiarized my brain-screening method!

That's right, although there is no modern mathematics in this world, it does not mean that they don't know the significance of mathematical talent to talismans.

The woman placed the scroll in her hand on the table, and the scroll slowly unfolded, with a blank space on it.

"But later my master said that this was just a formality, and he would accept me even if I couldn't do it. After finishing the questions in the book, I found it quite interesting. Later, I became his disciple and still liked to solve difficult math problems." The woman pointed her finger, and a question appeared on the scroll: "For this reason, I asked someone to create this magic tool to collect interesting questions."

There are people who collect this thing? They even made a magic tool specifically to collect it?

What a rich pervert!

"In the past few years, I have read all the math books in the sect, and searched for ancient math books everywhere. To this day, I have read all the math books I can find, and I haven't encountered a problem that can stump me for a long time." The woman looked up at Zheng Fa, her eyes sparkling, and her expression was full of excitement that could not be hidden: "The questions in your book are not difficult, but I have never seen them before, and the thinking method is also unique, but I am a little unsatisfied. Do you have more difficult questions?"

Zheng Fa felt that it was not something that could be said by a human mouth to say that he had read all the math books.

He had been thinking that there should be people with extraordinary mathematical talent in the Xuanwei world, and this person in front of him was one of them.

Modern mathematics is based on a set of axioms. When he wrote "Junior High School Mathematics", he had actually deliberately avoided this aspect.

But with his current level of mathematics, it is still inevitable to leave some traces - this is what the woman said was unsatisfactory.

As if seeing Zheng Fa's hesitant expression, the woman generously said: "I will exchange other difficult questions with you!"

... Who wants to exchange this?

Thinking of the other party's obvious identity as a monk, and considering the other party's persistence in coming to him on purpose, more importantly, the other party's unusual hobbies made him very scared...

Zheng Fa still said: "I do remember some math problems, I don't know if you have seen them."

He took out a pen and paper and wrote down a relatively simple fill-in-the-blank question from the previous monthly exam on the paper.

"This question..." The woman looked at the question Zheng Fa had written, frowning slightly and said, "It's a lot harder than the one in the book just now."

She said it was hard, but Zheng Fa could clearly see that she had the excitement in her eyes, like a tiger or wolf finding its prey.

It took nearly an incense stick of time for the girl to figure out the answer.

Zheng Fa took a look and found that the method was not standard, but the answer was correct.

In other words, the other party used the mathematical knowledge that already existed in this world to think about the answer, and it was really correct.

The woman finished the question, squinted her eyes, and seemed to enjoy it very much.

She asked Zheng Fa: "Is that right?"

"Yes." Zheng Fa nodded.

"Another difficult question!"

Zheng Fa: "..."

He still wrote another question.

"Are there any more?"

"..."

"The last question!"

"..."

"Question!"

Facing the girl who was asking for too much, Zheng Fa rubbed his forehead and felt his mind was empty.

This was the first time he met an addict who could drain others!

…

After meeting her mother, Miss Zhao rushed to the Seventh Young Master's courtyard.

"Zhao Jingfan!"

She pushed open the Seventh Young Master's study and shouted loudly.

On the desk, a head with disheveled hair looked up blankly.

"Where is Zhao Jingfan?" Miss Zhao asked.

"Sister?"

"Who are you? Zhao Jingfan!" The eldest lady opened her eyes wide and looked at the familiar face in front of her: "How did you become like this?"

"Sister! You are finally here!" The Seventh Young Master rushed over and hugged his sister's arm and wanted to cry: "I called you before, why didn't you respond to me?"

The eldest lady stretched out a hand and pushed away the Seventh Young Master's dirty face with tears streaming down his face, as if she was afraid that his tears and snot would get on her clothes.

She looked up and down at the Seventh Young Master, frowning as if she didn't dare to recognize him.

"Are you really my brother?"

"Sister! After so many years, you even forgot my face?" The Seventh Young Master was a little hurt.

"I can recognize your ugly face." The eldest lady shook her head and looked at the desk full of talismans: "I can't recognize you when you are studying hard!"

Hearing this, the Seventh Young Master felt even more wronged.

"Sister! I shouted for you to save me, but you came only now!" He complained, "Zheng Fa took the cane given by mother and forced me to look at these talismans... If you came back two days later, your brother would either be dead or crazy!"

"I didn't know you were so miserable now..."

The eldest lady shook her head with some regret.

"If I had known, you would have come back earlier to save me?" The seventh young master asked expectantly.

"If I had known, I would have stayed in Qingmu Sect for a few more days!" The eldest lady patted the seventh young master on the shoulder and sighed, "I didn't believe that mother said Zheng Fa was a talent, but now I believe it. He has made great contributions to our Zhao family and deserves a reward!"

The seventh young master: "?"

"Okay! Don't worry about Zheng Fa or not. I've invited Senior Sister Zhang back for you. She is a master of talismans. You should ask her for advice for the next two months, okay?" The eldest lady talked about business.

"Master of talismans?" The Seventh Young Master was a little confused, and turned to look at the talismans on the desk that had not been analyzed yet: "What about my talismans?"

"Don't worry about these!" The eldest lady waved her hand: "I will take you to listen to the teachings of Senior Sister Zhang. It will definitely be better than what you are doing now. With her guidance, you will definitely improve faster!"

The Seventh Young Master understood a little: "That is to say, I don't need Zheng Fa to teach me, let that Senior Sister Zhang teach me?"

"Yes!" The eldest lady asked with a smile: "It can also help you get out of this sea of ​​suffering. Are you happy?"

"I won't go!" Unexpectedly, the Seventh Young Master, who was still complaining just now, refused flatly at this time.
