I studied abroad in modern times

Zheng Fa had a headache.

He had every reason to suspect that the girl in green in front of him was the reincarnation of the calculator.

It’s so easy to calculate!

In addition to basic arithmetic knowledge, she has also mastered Tianyuan Technique, a form of arithmetic similar to solving polynomials.

What surprised Zheng Fa even more was that the girl also showed a technique called Zhushu, which was very similar to the limit-seeking technique he knew.

She can accurately and quickly give answers to any questions that require calculations in the college entrance examination, no matter how complex they are.

The other party's only weakness is probably proof reasoning.

She couldn't even understand why it was necessary to prove it.

From her, Zheng Fa could see a little bit of the arithmetic ethos of the Xuanwei world: emphasizing practicality over logic.

"Is there anything else?" The girl put down the question she had just written the answer to and raised her eyes, her face full of joy and satisfaction.

Zheng Fa discovered that the more difficult and perverted the question was, and the less he wanted others to solve it, the more excited the woman became!

"No more!"

Zheng Fa categorically denied it, otherwise he would think that this perverted game of asking questions and asking questions could be played by this insatiable girl for a year.

"Not a single question?"

"Not a single question!"

The girl stared at his forehead, her eyes full of suspicion.

Zheng Fa was very suspicious that the other party wanted to pry open his brain to see if it was really out of stock.

"Senior Sister Zhang? Why are you here?"

A woman's voice interrupted the silence between the two of them. Zheng Fa turned his head. The seventh young master stood behind a girl in red. It was the girl in red who spoke.

"Zheng Fa, this is my sister!"

The seventh young master introduced.

"Miss!" Zheng Fa stood up and saluted, and couldn't help but glance at the woman in green. It turned out that her surname was Zhang.

This person didn't announce his name at all when he came, and he didn't even consider whether he would let her into the house.

It seems that except for those questions, nothing else is important.

"I asked your servant for directions." Senior Sister Zhang thought for a while and replied. She also glanced at Zheng Fa and explained: "Zheng Fa seems to be quite famous in your family. I found him after asking someone. ”

"I'm not asking how you got here, I'm asking how you, a golden elixir, can do it yourself..."

The eldest lady waved her hand and walked to Senior Sister Zhang with a puzzled expression.

When Zheng Fa heard this, he was also surprised. This girl is actually a golden elixir?

Although he didn't know much about the world of immortality, judging from the eldest lady's surprise, confusion and even faint respect, Jin Dan should be very powerful, at least he was a big shot in front of the Zhao family.

So much so that the eldest lady would be so surprised to see Senior Sister Zhang in his yard.

Senior Sister Zhang seemed to understand this time and nodded, but then asked: "If I come in person, will the golden elixir break?"

"..."

Zheng Fa swore that he saw a choked expression on the eldest lady's face.

"I...he is my brother's book boy. If you want to see him, just ask him to be summoned. You look like the Zhao family is neglecting you."

The seventh young master on the side curled his lips.

Zheng Fa understood what the eldest lady meant. There was such a big gap in status between Master Jin Dan and Shu Tong.

One word can make him obedient and at his mercy.

He wasn't offended, which is probably the view of most people in the world.

"Didn't I come to your house too?"

"?"

A trace of doubt appeared on the eldest lady's face.

"Where I go, who I want to see, it's just random. What does it have to do with this person's identity?" Senior Sister Zhang glanced at the three of them: "It makes no difference to me."

"..."

Among the four people in a small courtyard, three were silent at the same time.

The eldest lady blushed.

The seventh young master gritted his teeth.

Zheng Fa... held back his laughter.

What does equality mean for all living beings!

When the eldest lady said that Senior Sister Zhang was a golden elixir monk, Zheng Fa thought that this person was quite approachable.

Now let’s see…

In my eyes, the Zhao family is no different from the book boy in the Zhao family.

I have the arrogance of never looking at who the other person is when I make friends.

There is no one who is more approachable than the woman in front of me.

The eldest lady's face turned green and white, and she was speechless.

"Junior Sister Zhao," Senior Sister Zhang suddenly said to her: "As cultivators of immortality, we shouldn't have too many useless things in our hearts. You... there are too many things that you can't let go of."

The eldest lady was stunned when she heard Senior Sister Zhang continue: "With your talent and diligence, it shouldn't take ten years to build the foundation. If you don't wake up, you will eventually be dragged down."

The eldest lady's face was stunned, as if she finally understood why Senior Sister Zhang was so rude in her words.

She showed a mixture of bitter smile and gratitude: "Senior Sister Zhang, you are a true monk. You can become a golden elixir in a hundred years. I..."

Senior Sister Zhang seemed to just say this just to make a point. When she heard what she said, she just nodded and stopped trying to persuade him. Instead, she looked at Young Master Seventh who was standing aside.

In front of the golden elixir monk, the seventh young master could not help but show some nervousness.

"This is my brother Zhao Jingfan!" The eldest lady hurriedly introduced: "I originally planned to take him to see Senior Sister later. I would like to thank Senior Sister Zhang for your kindness in going to Jingzhou to teach."

After saying that, she patted the seventh young master on the back and said, "Thank you a lot, Senior Sister Zhang? She is willing to teach you the talismans. You are lucky!"

So it turns out that Senior Sister Zhang is here to teach the Seventh Young Master the talismans?

"No, I don't like these." Senior Sister Zhang pointed at Zheng Fa's head and said, "And if you want to thank me, I'm very satisfied to see his thank you gift."

Zheng Fa touched the back of his head and felt that Senior Sister Zhang was pointing at the question in his mind.

If you think about it more horrifyingly, it's pointing to his brain.

Could it be that she is retribution for my love of collecting brains?

The eldest lady and the seventh young master looked at Zheng Fa blankly, and the emotions in their eyes made Zheng Fa feel very familiar:

Just like that, the look in Wang Chen's eyes when he and Tang Lingwu went downstairs -

Why?

…

"If you want me to teach you the Tao of Talisman, then I have to see your current level first." Although Master Seven was welcome, Senior Sister Zhang did not refuse to teach Master Seven.

On the contrary, she seemed to have a resolute and resolute character, and she started to teach the seventh young master in Zheng Court House, and even directly tested the seventh young master.

Zheng Fa was also very interested. He didn't mind that the eldest lady invited another teacher, because he was not sure that everything written in Old Man Bai's notebook was correct.

The role of modern mathematics, or topology, in Fu Dao has always been his speculation.

But he also knew very well that mathematics could be deduced purely theoretically, but talismans did exist in this world after all and had not been practiced. It was difficult for Zheng Fa to say that what he taught the seventh young master would be useful.

He has always had a lot of confusion about the talismans of this world.

Just like science, the solution of problems still needs to be related to reality.

Whether Old Man Bai's method is correct or not, as well as the many confusions about the runes, all require seeing the real runes.

When the seventh young master heard that Senior Sister Zhang was going to test himself, he couldn't help but look a little nervous.

At this time, the eldest lady on the side spoke: "This younger brother of mine used to be playful, uneducated and incompetent. If his level in the Tao of Talisman is not satisfactory to me, Senior Sister Zhang, please don't dislike me."

Zheng Fa sighed secretly. He believed that the eldest lady's belittling in advance was a good intention, even to protect the seventh young master.

but……

Zheng Fa looked at the seventh young master, and sure enough, a hint of darkness flashed across his face, and he bit his lower lip gently, making his whole person look even more tense.

Senior Sister Zhang nodded lightly.

"To understand the Tao of Talisman, you must understand Yuan Fu. The first question is, what exactly is Yuan Fu? Do you know?" She asked the seventh young master.

The seventh young master shook his head blankly, his face looking very ashamed.

Senior Sister Zhang's expression was neither happy nor sad, and she didn't seem disappointed.

She stretched out her right index finger and lightly traced it in the void.

A golden talisman appeared out of thin air, and suddenly spread into three streams of light, which penetrated into the foreheads of the other three people.

"Yuanfu is a kind of talisman." Senior Sister Zhang's cold voice came: "And in my eyes, the talisman is the world!"

The golden light formed by the talisman was a bit dazzling, and when it came close to Zheng Fa's forehead, he closed his eyes unconsciously.

When he opens his eyes again.

The world in front of me...is broken.
