In the whole book of "Huai Yi Strategy", she memorized the melons well.

Qi Muran was stunned for a moment.

"Good." He complimented.

Xu Shu held his chin and blinked.

Qi Muran: "Don't forget? ”

In addition, he really couldn't think of how the little guy could memorize such a whole book of "Huai Yi Strategy".

Xu Shu raised his head and thought about it with a rare seriousness: "It's not innate." ”

It's her grandfather who has trained her since she was a child, and she has a good talent, so she can never forget it.

Qi Muran was a little surprised: "Yes..."

Of course, Xu Shu understood what he meant, and nodded: "People with good talent can indeed achieve unforgettable through acquired training." But..."She looked at Qi Muran playfully, "Memorizing it doesn't mean that you understand, does it?" ”

Qi Muran laughed, the little guy was very transparent.

He took out three other books, "How long will it take to memorize these?" ”

Xu Shu took it and flipped it over, "An hour." ”

Qi Muran took the book away from her hand, "Then read it later, learn arithmetic first." ”

Xu Shu: "Arithmetic? ”

Two old-looking arithmetic books were placed in front of Xu Shu.

She flipped through it casually, and the first page was the Pythagorean theorem of Pythagorean strands, four strings, and five.

On the second page, chickens and rabbits are in the same cage.

Page Three...

Xu Shu: "Aren't these very simple? ”

"Simple?"

The little guy really doesn't know anything about arithmetic.

In the current Baoyi Academy, the most important thing is arithmetic, and there are very few who can learn it, and those who can learn it well, such as Zhang He, can rise to the top and become the prince of the country.

Qi Muran turned the first page, pointed to the five or six characters of the hook three strands, four strings, and began to explain to her what the Pythagorean string was.

Xu Shu: "It's just a right triangle." ”

Qi Muran: "? ”

Xu Shu grabbed a piece of paper, picked up the wolf hair he had just used, and drew a right-angled triangle very casually, "Isn't that so?" ”

Qi Muran held her hand: "Be good, don't make trouble." ”

The cold touch on his hand made Xu Shu shrink his neck, "You can take a look first." ”

Qi Muran reluctantly took the paper in her hand, and her hand paused slightly.

What the hell is his little one...

"Since you will, let's see the next one."

No matter how shocked he was in his heart, Qi Muran didn't show it at all.

Xu Shu was bored and moved his gaze from the book to Qi Muran's face.

Compared to the yellowed book, his face is still better.

How can this person's skin be so good that he can't even see the pores.

His delicate is as if God has taken a piece of superb white jade and carved it carefully, just right, one more point is too much, and one point less is not enough.

Qi Muran's facial features are very three-dimensional, which Xu Shu longed for in his previous life.

He always seemed to be shrouded in a layer of fog, but this layer of fog not only did not blur his eyebrows, but made his eyebrows and eyes more clear as if they were filled with water vapor.

Of course, Qi Muran found that the little guy was not listening, and he sighed helplessly: "Do you understand?" ”

Xu Shu immediately sat upright: "Understood." "Actually, I didn't hear anything.

He pointed to the chickens and rabbits in the same cage in the book, "Do the math." ”

"If you can't write it, the king will punish you."

Xu Shu sighed, and his heart was stable.

Isn't it just a matter of making a binary equation.

While holding the wolf hair that is not very handy, she wrote the equation, and complained while writing: "Your pen is so heavy..."

The black pen barrel is carved with dark patterns to carve a coiling dragon, and people without wrist strength may not be able to hold it.

Xu Shu looked at his pen every day, and he was very comfortable with writing and dipping in ink, and thought it was very light, but he knew that it was so heavy when he got it, as if it was filled with lead.

Qi Muran couldn't cry or laugh, this wolf brother had always wanted to use it, but he didn't give it, and others couldn't touch it, only this little guy would dislike it.
