Lin Banxia's own account book uses Arabic numerals for bookkeeping.

The handwriting on the form is, of course, also the simplified Chinese characters of the previous life.

She smiled and said proudly: "Your Highness looks at my account, can you remember it clearly?" ”

Even if the handwriting is crooked and there are things on it that you don't recognize, it is undeniable that this tabular form is very easy to understand.

The left side of the table is obviously all expenses, and the income column on the right is empty.

Xia Changyan pointed to the symbols and asked, "Miss Lin, what do these mean?" ”

Lin Banxia had been fighting with heaven and man for a while in his heart, and then he made up his mind at this time, and said with a smile: "These are numbers. ”

She pushed the teacup aside, turned around and took a cup of water and put it on the table, dipped her fingertips in the water, and wrote ten Arabic numerals from 0 to 9 on the table.

Then write 10 at the end and 11 to 20 on the next line.

The autumn noon sun was fierce, and the handwriting on the table was quickly evaporated.

Xia Changyan's eyes changed from doubtful to focused to thoughtful, and suddenly looked up at Lin Banxia.

Lin Banxia met Xia Changyan's gaze and sighed softly.

"Your Highness." The smile on Lin Banxia's face slowly disappeared, and instead of being solemn and serious, he said with a solemn and serious face, "I can't learn one of the ten thousand things that Master has mastered."

Master once said that if you take something out, it will definitely shock the world, but for me, it may not be a good thing.

However, His Royal Highness has the grace of knowing me and the affection for me, and I can't bear to let the Master's life's work be cut off from me. ”

Lin Banxia said, slowly turning his head sideways, looking at the mountains in the distance outside the village, as if looking at the non-existent master through the mountains.

Also look at everything from previous lives that does not exist in this world.

The sincerity and loneliness in her eyes were real at this moment.

"Your Highness can convince me and trust, right?"

The doubts in Xia Changyan's heart did not weaken in this last sentence of "right".

But he couldn't answer in the negative with such trust and sincerity.

After a long time, Xia Changyan said, "Miss Lin, tell me about your master." ”

Lin Banxia picked up the teacup, took a sip slowly, and then said softly: "Master said that everyone said that he was crazy, and that what he said was crazy.

Master said, "The earth is not square, and the sun does not revolve around us."

Master said that iron can float on the water, and people can fly in the sky like birds.

Master said that nature has given us everything we need, but we have only received less than 10,000 percent from it.

Master said that people need to borrow strength, but unfortunately he has not met the master, so he has no way to borrow strength......"

Lin Banxia took another sip of water, holding the teacup, and seemed to fall into memory.

There was silence in the courtyard.

These words should make Xia Changyan dispel some of his doubts.

"Your master is not a madman, he is a genius." For a long time, Xia Changyan said softly.

Lin Banxia raised his head suddenly, and tears appeared in his eyes at this moment.

"Your Highness, if the master is here, the master will definitely ......" Lin Banxia cried with joy, completely speechless.

Xia Changyan said gently: "Miss Lin, you can carry forward what your master has learned all his life, and your master will be happy for you when he knows about it in the future." ”

Lin Banxia nodded vigorously: "Thank you, Your Highness." ”

Xia Changyan smiled: "Miss Lin, can you write the previous numbers again?" ”

The housekeeper appeared silently and polished the ink himself, Xia Changyan laid the paper for Lin Banxia, and pressed the edges with a paperweight.

Lin Banxia shook his head, "Your Highness, I am more accustomed to writing on tree branches underground than pen and ink. ”

Lin Banxia stood up, took a branch, and began to write in the open space of the courtyard.

Compared with the paper, the handwriting on the ground is much neater, and it even has a sense of beauty.

Lin Banxia first wrote "0".

"Your Highness, 0 represents emptiness, nothingness, none. But numerically, this 0 has an indispensable role. ”

She then wrote nine numbers from 1 to 9 at a time below the 0, and finally wrote "10".

"Your Highness, please see, in this way, we can easily recognize the ninety-nine numbers from 1 to 99."

To be honest, Arabic numerals are too friendly for numeracy, and as an adult, it is a matter of minutes.

Lin Banxia didn't even need to write all the numbers, he only needed to write a few numbers in the first row, the second row, the first column, and the last column.

Lin Banxia stood up, took a step back and admired for a moment and said, "And so on, there can be thousands, thousands, hundreds of thousands, or even more, and you can master it in a moment." ”

Xia Changyan was going to record the pen and ink, but looking at the few lines of words on the ground of the courtyard, all the numbers were instantly imprinted in his mind, and he didn't need to write down, so he didn't forget it.

Even the housekeeper looked at the ground in shock, and then looked at Xia Changyan, as if he didn't know how to express the shock at the moment in words.

Lin Banxia was still insufficient, and wrote a vertical addition in another place.

"Your Highness, please see, in this way, the process of addition is simpler, and the reverse is subtraction."

Xia Changyan couldn't help asking, "But is there anything else?" ”

"And multiplication, division." Lin Banxia wrote two more equations.

Only then did he throw away the branch and stand up, "Your Highness, I use the branch to write, so I can see it." ”

On the small piece of the ground, the handwriting carved by the branches is clear and clear, the handwriting is neat, and the strokes are clear, which can completely see the skills of the person who wrote.

Xia Changyan's heart suddenly gave birth to pity.

For Lin Banxia, it is also for her master.

Before they met themselves, they couldn't afford to buy pen and paper, so they could only practice and learn on the ground with tree branches.

"It's not just eye-catching, it's good, it's very good."

Xia Changyan didn't have any jokes in his heart, he personally wrote Lin Banxia on the ground in four vertical styles on the paper, and then glanced at the housekeeper.

The butler immediately stepped forward and crushed all the handwriting on the ground with the soles of his shoes.

"Miss Lin, have you ever talked about this number?" Xia Changyan asked.

Lin Banxia shook his head: "His Royal Highness is the first." ”

Xia Changyan's expression was serious: "Miss Lin, she respects her teachers and talents, but what she has learned is a school of her own, and she is afraid that she will not be accepted by the world." ”

Lin Banxia nodded slightly and sighed softly.

"Please believe in this king, one day, this king will let the girl carry all this forward."

Lin Banxia turned around and bowed deeply to Xia Changyan: "Banxia thank Your Highness for your kindness on behalf of Master." ”

Lin Banxia finally breathed a sigh of relief, and this level was finally passed.

Although this level has passed, her glory, wealth and peace are tied to Xia Changyan.

But Xia Changyan can't grab the title of the crown prince, and he will be an idle prince in the future, and he will be able to keep himself safe if he is rich and noble.

Peace is the most important thing.
