Great Blue Night Watchman

"How dare you! I know how good Mr. Deng is as a human being!" Lin Su smiled: "Where is Brother Deng currently at?"

"The student dare not bother you with such a respectful address. The student is currently studying at White Deer Academy to prepare for the imperial examination in two years."

"White Deer Academy is the top academic institution in Da Cang. Only a talented person can enter it. If Brother Deng can enter here, he will be a talented person of his generation."

He still calls himself a brother...

Deng Qiushan sighed: "Master Lin, the student also heard what the master and my father said. Do you really think it is possible?"

"You think it's impossible?"

"There is an arithmetic department in White Deer Academy, which includes the world's arithmetic masters. They study "Nine Chapters of Arithmetic" every day. However, to this day, I have never heard of a calculation method that can increase the efficiency ten times. If it really exists, yesterday's student Asking for it should be another way of saying it.”

He made a special trip to White Deer Academy yesterday just to ask for help from the arithmetic department of the academy.

But, it was rejected!

Even though he was a student of the upper school of White Deer Academy and regarded the academy as his family, he was still rejected.

The suppression by the court officials is one thing, but more importantly: the academy's calculation department cannot solve this problem at all. If it can be solved, even if the direction of the wind is wrong, some students will eventually be willing to stand up. After all, if they take action to solve such a problem, then It is an excellent opportunity to become famous all over the world, and no one wants to miss it.

"The way of arithmetic has "Nine Chapters", but it is not only "Nine Chapters". It all depends on people. There are always some new methods that can be created... By the way, do you have a carpenter in your house?"

"Yes! Sir, are you going to do something?"

"I'll draw a sketch, and you ask him to make it for me quickly..." Lin Su picked up the pen and paper on the bookshelf and drew a very simple sketch. What sketch? abacus!

Deng Qiushan picked it up and looked at it, but he didn't know why.

Lin Su briefly explained the precautions for converting the sketch into a physical object, and then let him do it.

Deng Qiushan went out, found the carpenter in the mansion, and started working immediately.

In less than half an hour, an abacus appeared in Lin Su's hand.

Deng Qiushan was waiting for Lin Su's demonstration with great interest, but at this time, the people from the Ministry of Household Affairs had already arrived.

Most of the people who came were young people. Judging from the clothes they wore, most of them were of low quality. The housekeeper sheepishly introduced that these people were all from the Accounting Department of the Ministry of Household Affairs. The list given by the Lord was forty-six people. Twenty-seven people, the rest, some are not in the department, some have other important things to attend to...

A voice came: "Aren't Zhou Su, Zhang Jun, and Li Yangfei here?"

Lin Su looked up and saw Deng Hongbo. Old man Deng was standing on the steps with his clothes wrapped around his face, his face looking quite evil.

Twenty-seven people knelt down at the same time to see Lord Deng...

The butler bowed and replied: "Sir, these three old slaves know that they are the backbone of the Accounting Department, and they are indispensable for this matter. As soon as the old slave entered the Accounting Department, he was looking for them, but these three people refused. They said they had accepted Mr. Li ordered us to calculate the funds of the Ministry of War."

Deng Hongbo was furious and his beard was flying. The Ministry of War's budget calculation had already been completed. Just the last remaining balance, could these three elite soldiers and generals be used? When he fell ill, all three of them were busy in the office. When he planned to take action, all three of them were occupied. The Mr. Li they mentioned was the one who closely followed Mr. Shangshu and had a hard time with him, the Zuo Shilang, face to face. The right servant who carried it...

Lin Su quickly said: "Nothing! Enough of these people!"

enough?

Deng Hongbo's eyes suddenly opened wide...

"Come, let them all come to the study!"

Lin Su turned around and entered Deng Qiushan's study. The twenty-seven people also came in with their heads lowered, feeling uneasy in their hearts.

They knew Master Deng's mission, and they also knew that it was impossible to complete it. If they were suddenly involved, nothing good could happen. They might be blamed for not being able to complete the mission.

Lin Su spoke: "Do you understand why we asked you to come here today?"

Some of the twenty-seven people nodded, some shook their heads...

Lin Su made the task clear: "What you have to do is to gather the efforts of twenty-seven people and spend half a month to complete the account review of the Account Department last year."

"Sir...this can't be done!" A young man raised his head.

"Yes, sir, it's not that the little people don't do their best. Even if the little people are exhausted from calculating the room, it is impossible to complete this task. It is a small thing for the little people to be exhausted, but it is a big thing for the adults to be blamed by His Majesty."

Suddenly, the study room became lively...

I said everything I dared to say but didn't dare to say, and everything I could say but couldn't.

The abacus in Lin Su's hand clattered, and all sounds were muted...

Lin Sudao: "Some things seem impossible, but they are actually possible. How about we do a test on site?"

A young man at the front said: "How do you want to test this?"

"Each of you report a number to me, no matter how big or small, and I will add it up for you! After you report it, I will calculate it. Do you think it is possible?"

Everyone was stunned!

is it possible?

How can it be?

The young man blinked: "Sir, you said the amount doesn't matter, it can be tens of thousands or tens of millions?"

"Can!"

"How long is the interval between the two sets of numbers?"

"When your voice falls, the second person can count!"

Deng Qiushan, who was at the door of the study, was shocked all over. He suddenly raised his head and looked at Lin Su in disbelief.

Lin Su waved to him: "Come here, Brother Deng will write down the number they quoted, so that you can check whether my calculation is accurate at the end."

"good!"

Outside the study, a little beauty hid under the window and watched quietly. Suddenly, there was another person in front of her, and it was her father. The little beauty suddenly jumped and was about to run away. Her father stretched out his hand and pressed on her. Her shoulders were not allowed to move, so there was one more person secretly watching...

Twenty-seven people stood upright. Deng Qiushan stood by the table with a brush in his hand, and Lin Su's hand pressed on the abacus: "Let's start!"

The young man at the front reported the number first: thirty-seven thousand five hundred and twenty-one two-three cents and four cents...

Lin Su moved his fingers, and the beads clicked. After he finished reporting, the beads were silent...

The whole place was quiet...

"Continue to report!" Lin Su said.

The second person reported the number: forty-two thousand six hundred and thirty-two two-four cents and three cents...

"continue!"

The third person reports...

"Don't wait for me to remind you. After the person in front has finished reporting, the person behind will pick up on his own initiative!"

The people behind were confused...

catch!

Pick up again!

Still pick up...

Deng Hongbo's face outside the window is changing. What song is he playing? On-site calculation? What's your plan? The Accounting Department is the most efficient place in arithmetic. Their calculations are ten times better than others. Their calculations are divided into tens, hundreds, thousands, and ten thousand. What does this mean? Thousand-character counters use one as a thousand, and when they encounter a thousand, they use a thousand-character counter to count. Therefore, their calculations are much faster than those of the outside world.

But no matter how fast it is, it can't be this fast...

Ten people, fifteen people, twenty people...

The title written by Deng Qiushan is already a full page...

Twenty-five, twenty-six, twenty-seven...

"Report them all!" The last person finished saying the number and added four words.

Lin Su glanced at the numbers on the abacus and read: "One hundred and twenty-four thousand six hundred and twenty-seven two-three cents and eight cents."

The whole process takes half an hour.

Everyone looked at each other, is this the end?

There are 27 sets of numbers, each number is in the astonishing tens of thousands, and there are zeros and rounded numbers, and he reads it out at such a fast pace. Deng Qiushan never stops writing just writing a topic, and he is strange here Just pull the beads a few times and the calculation is over? Why is it so untrustworthy?

It must have been written randomly!

Lin Su understood their looks: "Please review it. After verifying my results, we can move on to the next step." Shi Shiran left the study.

In the study room, twenty-seven people took it out as quickly as possible and began to review it. It took a full hour, and with the combined efforts of twenty-seven people, the results came out. The moment the results came out, everyone was stunned.

The answer given by Lin Su is completely correct, exactly!

There was a loud shout in the study, and everyone exploded...

Lin Su appeared at the door of the study room again, and was met with a group of fanatical eyes, as if they were looking at gods. Lin Su was also a little proud. He had never used abacus in that world, but he knew the rules. With Wen Xin's blessing, as long as he knew the rules, he would become an abacus master in the blink of an eye. Take it, Wen Xin, Xin Wherever it goes, where its hands go, and where its brain goes, it is truly powerful.

Lin Sudao: "Twenty-seven groups of seven-digit numbers can be accumulated in half a quarter of an hour. People in the world think it is impossible, but I can! Is this my ability to reach the sky? No! It's just this new algorithm that subverts to your understanding.”

New algorithm!

Twenty-seven people, plus Deng Qiushan, Deng Hongbo outside the window, and Teresa Teng, were very excited. They had witnessed the magic of this algorithm with their own eyes.

Can you ask him for help? If he is willing to take action, he can approve the full-year accounts in half a month... it is really possible!

"Want to learn?"

When Lin Su said these three words, the whole room fell silent.

What's the meaning? Why is everyone so quiet? If you don’t cheer for this handsome guy, it’s very unfulfilling...

After a long while, the young man at first asked cautiously: "Sir, you mean... you can teach us such magical skills?"

"Of course you can!"

The twenty-seven people looked at each other, all surprised, happy, and a little unbelievable...

"It seems that people in the officialdom are very reserved!" Lin Su said: "Okay, no matter whether you express your stance or not, I also know that you want to learn. Let's start teaching now... This set of algorithms is called abacus. , I need to use a tool, I named it the abacus. The abacus seems simple, but in fact it contains the great knowledge of calculation. The bead on the top is represented by five, and the bead on the bottom is one, two is two, and three. It’s three, it’s four, it’s four…”

He explained the basic framework of the abacus.

Everyone's eyes are as bright as stars, and they feel like they have heard of the great road.

"After understanding the most basic framework, there are the rules of operation. The rules of operation have an addition formula. Everyone should memorize and memorize it...one up, one up, two up two, three down, five divided by two, four to six, and five to five. One forward, six up, one out, five forward, one..."

He was chanting the formula in his mouth, and the abacus beads were flying in his hand to demonstrate...

In the study, the shadow of the sun moves westward...

A circle of lotus flowers appeared at Lin Su's feet. A strange fragrance filled the air. There was also a faint holy light all over his body. When he spoke, golden lotuses faintly formed in the void...

Preaching icon!

The Golden Lotus of the Great Dao, which only the top Confucian preacher can possess, grew from under his feet, and the Golden Lotus spitting out from the mouth of the Saint preached vaguely appeared in the air, but no one present was even remotely alert to these.

They were brought into preaching, and there was only the Dao without everything. Everyone's understanding ability was also improved to an incredible level. The understanding of abacus changed from vague to clear, and gradually became clear. Everyone had the feeling of hearing the Dao for the first time. ecstatic……

An hour later, Lin Su finished talking about abacus.

Everyone woke up from a dream and bowed at the same time...

"Sir's wonderful skills are truly as good as those of heaven. I wonder if he is a top scholar at White Deer Academy?" The young man was surprised.

The rest of the people also stared at him with burning eyes and asked the same question.

They didn't know Lin Su, but who in the world could possess such a magical skill? Undoubtedly, only the arithmetic department of White Deer Academy is the top scholar, and the arithmetic department of Bailu Academy is the ceiling of arithmetic in the world.

Lin Sudao: "This question is not important. The important thing is... you just rely on abacus, which is not enough to ensure everything is foolproof. I have another method that can be used in conjunction with it to get twice the result with half the effort! This skill is called... Da Cang Talisman , turning complexity into simplicity..."

He stretched out his hand, and a piece of paper flew up out of the air. The pen fell from Lin Su's hand, and written on it were 1, 2, 3, 4...

This is one, this is two, this is three...

This is the decimal point. If the unit is "two", the first digit after the decimal point is "money", and the second digit after the decimal point is "cent"...

In this way, a long and complicated string of text is turned into a number, which is more intuitive and easy to calculate...

Another hour of explanation, and the image of preaching reappears!

The piece of paper in Deng Qiushan's hand was also marked with Arabic numerals. With such annotation, his heart beat faster. It really became simple, convenient and intuitive...

The matter is not over yet, here comes the most important skill...

Lin Su raised his hand and drew a gridded chart on the paper...

"You all are from Da Cang Accounting Department, but please forgive me, your accounting methods are extremely primitive and backward. You cannot distinguish between receipts and payments, and your calculations are unclear. Therefore, I will pass on to you a new accounting rule. I will It is named: Receipt and Payment Accounting Method..."

The new numerical symbols are included in the table. The front is revenue, the back is branch, and the balance is obtained after netting...

Clear, simple and convenient...

The missionary vision this time was particularly strong, with golden lotuses jumping for joy, and it seemed that we felt the great changes of the times...

After all the teachings were completed, Lin Su left the study. The golden lotus beneath his feet shook, soared into the sky, and disappeared outside the sky.

The study door suddenly opened, and Deng Hongbo appeared at the study door: "What do you think?" He eavesdropped outside the window for three hours, but after all, he was not an arithmetic talent and did not understand arithmetic, so he didn't quite understand.

"Sir, this is a skill from heaven!" The young man's face flushed with excitement: "I can guarantee that even if there are only ten people, the review can be completed within half a month!"

"Really?" Deng Hongbo grabbed his shoulder suddenly, and his face suddenly turned red as blood.

"I promise I can!"

Another person stood up: "Absolutely!"

"Then...what are you waiting for? Go back to the Accounting Department and start working all night!" Deng Hongbo shook off his clothes and rushed out of the study. At this moment, how could he feel sick at all?

The young man rushed out a few steps and turned back suddenly: "Mr. Deng, that gentleman... you invited him from White Deer Academy yesterday, right? Who is he?"

"He... is Lin Su, the number one scholar Lin Su!"

What?

Everyone present was shocked!

He is not the top scholar in the arithmetic department of White Deer Academy at all!

He is the troublemaker in the literary world, the one who is kept secret by the big guys in Beijing!

He is famous all over the world for his poetry. How could he be a peerless genius who pioneered arithmetic?

Deng Hongbo urged them to go...
