Poor Ghost Up and Down 2000

"This..." Kong Rong hesitantly took a simple calculation from Gu Nan's hand.

The handwriting on the cover is not completely dry, it should have been written not long ago, and from the book line, it can also be seen that this is a newly edited text.

Do you use the newly edited book to teach? Even though he believes that Gu Nan will not do things casually, he is inevitably a little worried.

He opened the book in his hand and read it first.

But Xun Yu's eyes skipped Jian Suan and Ge Wu. He should have read the general content of these two books a few days ago, but he was more interested in how Mr. Gu would teach people to practice calligraphy.

So he reached out and picked up the calligraphy book.

Well, pinyin, what is this?

···

Without disturbing the two of them reading, Gu Nan turned to look at Lingqi, saw her holding a bag of crushed sugar, and asked.

"Where did Qi'er get this candy?"

"This is brought by Mr. Xun. Do you want to eat it, Master?"

Lingqi said, and handed the candy to Gu Nan.

"Okay, thank you Qi'er." Gu Nan patted Lingqi's head with a smile, took the paper bag and started to eat.

Lingqi stood aside and looked at Gu Nan with a slight smile.

He walked to the side of the yard and sat down under the eaves.

He untied the long sword from his waist, put it across his lap, held the hilt in his hand, and looked up at the trees in the yard.

The tree has grown taller than before.

But she didn't seem to have changed anything, and she was still generally useless.

I remember one time, she heard her master say that this world is really annoying, and now she understands what he meant.

Master wants to do two things, one of which is to change the world.

She wants to be with the master.

Perhaps it is a coincidence, history is always very similar.

Hundreds of years ago, there was also a girl wearing a white robe and holding a sword, sitting under a big tree, thinking the same thing.

······

When Xun Yu and Kong Rong raised their eyes from the book in their hands, most of the candy Xun Yu brought to Lingqi had already entered Gu Nan's stomach.

He looked at Gu Nan with a wry smile: "Mr. Gu, I brought this candy to Qi'er."

"Hmm." Gu Nan put away the paper bag in embarrassment, and finally licked his fingers.

"Ahem, let's talk about books."

This can't be blamed on her. When she was marching outside, she ate only dry food for several times. It was rare to eat something tasty, and she really couldn't stop.

Xun Yu smiled and wiped the sweat from his forehead.

It seems that next time you come, you should bring two servings of this candy.

Xun Yu smiled politely.

Kong Rong on the side didn't pay attention to these.

Holding the book in his hand with a serious face, he looked up at Gu Nan.

"Mr. Gu, did you write this book last night?"

At the beginning, he didn't pay much attention to the book, but there were many things he didn't understand at first glance.

He knows some arithmetic, but the content in this book is completely different from what he knows.

After he understood all these things, he couldn't put down the book lightly.

Using the method in the book, the general calculation can be more than doubled?

He couldn't believe it. It was written overnight. It can be said that it is a brand-new arithmetic. It is impossible for even a genius to write it overnight.

Gu Nan didn't speak yet.

Xun Yu spoke first and explained.

"Mr. Kong, of course it is impossible to write the contents of this book overnight. These are all learned by generations of teachers from Mr. Gu's school. When I came to borrow books before, I heard from him that her teacher's school These books are the result of collecting inductive theories from generation to generation.”

"And her master's request, I think, is to pass on to the world when she completes her studies."

"Mr. Gu." Xun Yu looked at Gu Nan with a smile in his eyes.

"I guess that's what you're doing, right?"

Such a wonderful person, he really regretted not getting to know him earlier.

-------------Chapter Dividing Line---------------

"Uh, what you said is pretty much the same."

So, what are you doing looking at me with such a smile?

Gu Nan's back was haired by Xun Yu's gaze, and he moved his body sweating.

Sure enough, as I thought, this Mr. Gu wants to start with Qingzhou and spread the word to the world.

Xun Yu narrowed his eyes with a smile, it was a big undertaking, and definitely not an easy one.

This road is difficult to ascend to the blue sky.

He didn't try to persuade Gu Nan, because he thought that even if he persuaded, Mr. Gu might still answer him with that sentence.

Some things are not done depending on how possible they are, but they will be done even if they know they are impossible.

He didn't know where such an idiot came from. He looked at the book in his hand and smiled helplessly.

Oh, probably, it was also passed down by the teacher.

Only teachers who do this kind of thing will teach people like this, right?

He also couldn't tell whether his heart was filled with laughter or respect.
