The left side of the book has been accompanied by Fan Painting for many years, and she naturally knows when the owner can't be messed with and how long it will take to cool down.

It was for this reason that when she was close to her, she dared to knock on the door of the main room with a pot of water, and hurriedly closed the door after entering the house.

At this time, Fan Huashi neither handled official business nor read books, and only stood alone in a daze.

It seems that such a waste of time is really infuriating.

Shuzuo took the opportunity to pour water and asked, "Pavilion master...... The latest question...... It doesn't seem like it's a mathematical problem...... I don't understand how to read it......"

"If you understand, you will understand, and if you don't understand, you don't have to understand." Fan Huashi only said stupidly, "I shouldn't ...... It's me who shouldn't ......."

"What should it be?"

"You shouldn't have written that question." She said, as if she regretted it, and she was about to help her up, "Pick it...... Let's take that question off......"

Shuzuo had never seen the pavilion owner like this, so he only asked in a panic: "Is the pavilion owner afraid...... The man really answered the third question, do you want to fulfill the contract? ”

"No...... I'm afraid he won't be able to answer...... Gone astray......" Fan said, his forehead already sweating, "I shouldn't have asked this question...... ...... shouldn't have been"

"This ...... Does the owner want him to answer or not? ”

"Naturally, I want to...... But ......" Fan said together, "No...... It's better to pick it up. ”

Shuzuo stroked her to sit down, and persuaded her: "Since the owner wants to know the answer, why not let this person answer?" It's just mathematical thinking, how can you go astray I really don't understand, but since the owner has this concern, how about we pick it again tomorrow? ”

"......" Fan Huashi pondered for a moment, then only sighed bitterly, "That's it, he has been in the library for so long, he should have discovered that." ”

"What?" Shuzuo asked puzzled.

"Nothing." Fan only grabbed the left arm of the book and said, "Tomorrow morning, you will be the first to come, whether you have an answer or not, you will immediately remove the question." ”

"Hmm." Shuzuo nodded steadily, and then put down the pot, "This is the case for two days in a row...... The librarian, the one who answered the question, I'm afraid it can only be the one in the library, right? ”

"Yes." Fan Huashi combed it out, drank a sip of water, and then stabilized his heart, "This person is a beginner in mathematics and physics, so he solved two problems in a row, and he was ingenious, but the business is entrusted in front, I just know it, don't make a noise." ”

"Well, Zhu Qi just asked me why the library has been locked up lately...... I only said that it was the above arrangement, and it seemed that it was going to be impossible to hide, and it began to spread that there were learning ghosts in the museum, and the problem was solved every night......"

"Let him be quiet for a day." Fan Huashi got up and opened the side window, breathed a sigh of relief, and came back with relief.

Shuzuo asked again: "Since the hall master knows that the scholar is the answer, why don't you see it?" ”

"I've seen it." Fan Huashi stood in front of the window, closed his eyes and said in the wind, "Words are boring, it is better to know each other with mathematics and science." ”

"And how did the owner get to know him?" Shuzuo asked.

"I can speak well and think well, but I am afraid that my heart is not good." Fan replied casually when painting.

"Hehe, how can you break people's hearts if you don't see them?" Shuzuo smiled, "I'm afraid the hall owner has forgotten that the person who answered the second question can spend the moon with you...... Hey hey ......"

Fan Huashi suddenly turned his head, turned his back and said: "He doesn't know this rule, he only counts the people in the ink museum, and outsiders don't count." ”

"Okay~ Anyway, the final interpretation is the owner's~" Shuzuo turned around to leave.

"By the way, don't tell him the reward for solving the problem."

"Don't say, don't say~"

……

For Tan Ying, once indulged, time always flies quickly.

Before I finished a few books, the clock rang at noon.

Shuzuo also came on time with a dinner plate as promised yesterday.

"My sister is so punctual." Tan Ying smiled and put down the scroll in her hand.

"Hmph, I can tell you, it's not good to be rude to the hall owner like this." The door was locked in the left side of the book before he hurried forward, pretending to be angry and said, "The hall master has a problem waiting for you this time!" ”

"Haha." Tan Ying laughed, "It seems that I have ruled out a circle, and I found that I can only answer." ”

Shuzuo smiled helplessly, and then set up the dinner plate: "You really have ingenuity, just read these books of mathematics and science, and you answered such a question, you have to take it." ”

"It's just a fluke." Tan Ying grabbed the fast child and said, "When there is no one at night, I will go for a while, and the third question is." ”

"You two are really weird." Shuzuo put the plate on the left, propped his arms on the table, and held his chin and said, "It's been so long, I haven't seen it." ”

"I've seen it." Tan Ying pursed her lips and said, "Words are boring, it's better to know each other with mathematics and reason." ”

"Ah......" Shuzuo always felt as if he had heard this, so he also asked, "Then how do you get acquainted with the owner of the museum?" ”

"It's true that the math is true, but the heart and mouth are inconsistent, and it's still difficult."

"It's still accurate......"

"Alright, I'm going to start asking questions." Tan Ying chewed the rice and raised her eyebrows slightly, "Are you ready?" ”

"Good...... Okay......"

I don't know why, Shuzuo looked at him and felt a kind of fear......

As it turned out, her fears were right, and for the next whole hour, she experienced the torture of learning.

Tan Ying did not ask specific questions like the curator, but explored axioms and relationships throughout the whole process.

It's just some overly basic questions, but it's dizzying to think about.

He would ask whether the pi in the book was measured or calculated, how the quantity was measured, and how it was calculated.

He would ask which formulas were "just prescribed" and which were "derived".

He would also ask how to express a number to the power of 1/2 and whether there was some kind of transformation between geometry and equations.

Shuzuo's knowledge is limited, and he can only do his best.

The only good news, or the biggest bad news, is.

Eventually, many of these questions point to a specific fragment.

This fragment is not even half a copy.

It's not that there isn't a front half or a back half.

Rather, it was physical, torn from the top left to the bottom right, and half of it was lost diagonally.

What Tan Ying shows is the half that has been torn off and has not been stapled.

He made it up one by one, and he barely managed to put together a dozen pages.

The whole process is the same as a treasure hunt, there is a piece in this book, and a piece is hidden in that corner, and it is here to spell "The Green Mountains of the Valley of Thorns".

The reason why Tan Ying collects and patches together with relish is only because just looking at any half of the page is enough to be fascinated.

It is said that it is a fragment, and the content is also hand-drawn, so it should be called a manuscript.

Because it is a manuscript, the content is also extremely scattered, with only many formulas and figures, and no annotations.

For example, the most complete fragment is a triangle made of numbers.

The first row at the top of the triangle is 1.

The second line is 1, 1.

The third line is 1, 2, 1.

Four: 1, 3, 3, 1

Five: 1, 4, 6, 4, 1

Six: 1, 5, 10, 10, 5, 1

And so on, forming a standard, endless pyramid of numbers.

As far as Shuzuo is concerned, she only instinctively perceives that the triangle is beautiful.

But Tan Ying was shocked at first sight, isn't this Pascal's triangle?

The law of this triangle is easy to summarize: each of these numbers is equal to the sum of the two numbers above it.

On the surface, it's a useless, just plain glamorous thing.

But if you expand (1+x)?, you will find that for any positive integer n, the coefficients of the expansion perfectly correspond to the n+1 row of the triangle.

For example, (1+x)3=1+3x+3x2+1x3 perfectly corresponds to the fourth row of the triangle: 1, 3, 3, 1.

In the words of a math teacher, this is a binomial coefficient, a geometric arrangement in a triangle.

It is a pity that although the mainstream mathematical community calls it Pascal triangle, in fact, this figure was first independently proposed by Jia Xian in the Northern Song Dynasty in the "Interpretation of Lock Arithmetic", and was later recorded by Yang Hui in the Southern Song Dynasty in the "Detailed Explanation of the Nine Chapters of Algorithm", so it is called Yang Hui triangle or Jia Xian triangle in China.

Although the two sages preceded Pascal by centuries, they did not make much of a splash at the time.

On the contrary, Newton developed such a masterpiece as the binomial theorem on the basis of Pascal's triangle.

Now, this triangle could have appeared much earlier.

The innumerable seeds of wisdom are just lacking in the soil of an era.

In the library, the more the book is turned back, the more I can't understand it, but I also feel that the author of this codex is more powerful.

Contrary to the extensive exposition of the arithmetic, there is only a combination of figures and figures, and there is no explanation.

Even if it is mutilated, it is indescribably beautiful.

Although it is incomprehensible, very few of them can still see what the author wants to do.

For example, calculate the volume of a curved wine barrel.

For example, calculate how to borrow the most profitable.

It's just that this form of numbers and graphics changing back and forth has never been seen in the book.

She could feel that the author of the codex was trying to find a pattern between numbers and figures, and he seemed to have touched something, but he could not put it into words.

But even so, the book can confirm at least one thing.

"This ...... It must be ...... Curator's Codex...... I've been reading her digital writing for many years, and I can't go wrong. At this time, Shuzuo covered his mouth and was surprised, "No wonder she said, you should have discovered this for so long!" ”

Tan Ying heard this expected answer, and only raised her head slightly, a moment of confusion.

Words are boring.

It's better to know each other by mathematics.

I see, I know what you're arguing about.

I get it, you've been waiting.

Even if it's a lifeless wait.

You have also left behind the shattered Dao heart, the fragment of your soul.

Seeing that Tan Ying was crazy, Shuzuo hurriedly asked, "These ...... Where did you find it? ”

"Every place." Tan Ying raised her hand and looked around, "It's strange to me, haven't you anyone else found such an important thing?" ”

Or ...... No one can read it, just throw away the drafts or bookmarks of the previous people. ”

"Or?" Tan Ying got up and pointed to the sky, "Correct, if you know each other by mathematics and physics-

"I am Firefly, she is Haoyue.

"At her feet, I am willing to be a dog."

……

Late at night.

Tan Ying finally finished the math, turned off the lights, and walked out of the library, breathing a long sigh of relief before walking towards the lobby.

Standing in front of the board, he saw the question he was looking forward to.

Just as he was about to pick up the pen.

Footsteps from upstairs were heard.

Tan Ying paused for a moment, but as if she hadn't heard, she unfolded her writing carefully little by little.

Fan Huashi walked down the stairs and paused when he saw Tan Ying's figure.

But as if he hadn't seen it, he gently brushed his sideburns and left with a small bag and a smile.

It was a magical and romantic scene.

But for Zhu Qi, who was hiding under the front desk at this time......

He's fucking dead!

The owner can't see this person!

！

It's really a ghost!

Only I can see it as a pure yuan boy like me for more than 20 years!

But just now the pavilion owner laughed again??

In the many years since I came to the Ink Museum, I have never seen the owner smile so treacherously......

Don't......

The owner of the museum is also a ghost?!

Ahhh

Mozi! Ink Saint! Mo Zhai Mo Grandpa!

Manifest thy spirit! Save our family!

……

The next morning.

Fan Huashi slept until four o'clock in the morning, and then woke up naturally.

She usually wakes up before the hour and is not late.

But last night was special.

Although I don't believe, I don't understand, I can't be.

But she always felt very ritualistic, and when she woke up, she would have to face something amazing.

So she slept soundly and woke up with plenty of energy.

The morning grooming was not hurried, and the ink was sorted out in the mirror before going out.

I didn't dare to go too fast all the way, and I was reluctant to walk too slowly, so I walked for a moment before I saw the ink museum.

From a distance, she saw two large carriages parked in front of the Ink Pavilion, and then sighed weakly.

I think there is a big owner coming, I'm afraid I have to deal with it first.

When I entered the courtyard, there was no one else, and I saw the porter coming in a panic.

"The owner, there is a guest ......"

"Hmm." Fan Hua breathed a sigh of relief, and then walked into the museum.

But as soon as she entered, she was dizzy.

Black pressed.

Lobby Black Press...... It's all people......

It's all ink......

The Great Inkman.

Seeing the hall owner enter the hall, everyone in the hall bowed down and made way for a passage.

The passage stretched little by little, until it reached the board at the top of the staircase.

An inexplicably tall, inexplicably black tall figure is standing there.

In this silence, this person seems to have felt the arrival of Fan Huashi.

He only turned back slowly.

It was a hazy, dark face that I couldn't see clearly when I passed the fan painting.

Said the hazy and hoarse words:

"There is nothing wrong with wrong thinking, but those who promote falsehood are wrong.

"Bachelor Fan.

"Are you still in that paradox?"

Phew.

Fan painting fell in response.

Like a piece of paper.

……

Adjacent to his own time, Qin Xue Palace.

Bai Pi ran all the way to the lecture hall like a big toad being fried.

"Si Ye! Stop! Stop! ”

The bachelor in the hall immediately turned around, thinking to himself what kind of trouble this Bai Xuebo was making again.

Fan Ya was suddenly startled, knowing that Bai Pi could mix and mix, and if he was forced to make such a noise, something would definitely happen.

Sure enough, Bai Pi ran all the way to the stage when he entered the lecture hall, and whispered to Fan Ya's ear.

"Mukden...... Wu Xiao...... Wu Xiao arrived early...... Straight to the ink museum......"

Fan Ya was shocked: "How can you say it!"

！ ”

"I didn't give us any news at all, this is still news from the garrison, and it was handed over by the Hinado." Bai Pi grabbed Fan Ya and said, "Tan Yingke is still in the Ink Pavilion." ”

"What a tassel!

Oh my drawing!

！ Fan Ya hurriedly turned around and jumped off the high platform, and said to the full hall: "You wait for self-cultivation!"

”

"Self-study, self-study!

Bai Pi also commanded to run out.

But I saw Yingyue suddenly get up: "Bai Xuebo, but Tan Ying is in trouble?" ”

"Alas, you don't care!

Bai Pi hurriedly waved his hand.

"I've got to take care of it!

Yingyue chased after him.

"It's really ......" Bai Pi hurriedly whispered, "I don't know what will happen, I'm really worried, go to the door of the ink pavilion, don't make a noise." ”

With that, he hurried out of the hall and went straight to the direction of the sacrificial wine.

Although Ying Yue doesn't know what to do, there is one thing he will not change.

"Brothers! Benmo Museum! Save Tan Ying! ”

He raised his arms and rushed forward.

Just when everyone else was still confused.

Xiaoqian, who was skipping class, immediately grabbed the pen and shouted the slogan:

"Fake ink has ...... No, no...... Anyway, materialism should stand!

”

She then pulled Ji Qinghuang and rushed out.

The square of the Lyceum.

Yingli is strolling here.

She was originally out of some not-so-just purposes, so she reluctantly agreed to the request of a thief teacher and took over Zou Shen's homework for the time being.

But I found out after taking the coursework.

That's not the purpose.

That person, he went to the ink museum.

It's just for vinegar to make dumplings.

No vinegar as a result!

Play with this!

was in the midst of this boring divine injury, but saw Yingyue Sazi running over, shouting in his mouth, "Benmo Pavilion!" Save Tan Ying! ”

Yingli instantly greeted him with a JO face.

"What's wrong again?"

"I don't know!

Ying Yue hurriedly grabbed Ying Li and said, "But this matter is not small, Sister Li should also call a helper!" ”

"You are quiet first...... "Ying Li's eyebrows tightened, and JO gradually disappeared.

As long as she is calm and not JO, she will immediately solve the equation of Lianli Moguan, Tan Ying and Fengtian to guide the way.

"Stay well, be sure to stay in the school palace." Ying Li hurriedly pressed Ying Yue, "Wu Xiaozi doesn't know that Tan Ying is in the Ink Pavilion, and if you are so loud, it will arouse suspicion." ”

This idea was too jumpy, and Ying Yue fainted on the spot.

But he believed in Sister Li, so he didn't ask for a reason to greet Xiao Qian, Ji Qinghuang and others who were chasing after him.

"Ahh......h Let's go back and self-study, self-study. ”

Everyone has also passed a hip-hop past.

Only Xiaoqian is sorry.

This lesson is so boring, we have all the pen and paper ready, and we are looking forward to it.
