Chapter 67 Gu Xu’s Lenovo (two in one)

However, Gu Xu quickly dismissed this idea.

On the one hand, the intelligence quotient of the characters created by the "touching the eyes and soul" technique is really limited.

The brain of this young boy in black is probably equivalent to that of a ten-year-old mortal child - at this moment, he is looking at documents under the guidance of Zhao Xinran, while writing on white paper Tu Tu draws; occasionally he miscalculates a few numbers, which Zhao Xinran points out sternly.

"It is indeed arithmetic, even the paper man will feel a headache after looking at it." Seeing this scene, Gu Xu couldn't help complaining in his heart.

According to the National Master, the time it takes for each person to calculate the results will become an important reference indicator.

If he wants to stand out among the candidates, he must find a better way to solve the problem in a shorter time.

…………

Mo Li lay on the table and thought hard.

He picked up the pen, recalled his notes, and wrote down the names of the talismans one after another on the paper - "Rokko Yin and Yang Talisman", "Shutchi Talisman", "Flying Talisman" , "Lucky Talisman"...

But he really couldn't think of any of these talismans that could help him solve the current problem.

“I really don’t understand why the National Master would propose such assessment content,” Mo Li scratched his head and thought distractedly, “Estimating the expenses of the Luoshui Conference has its own responsibility from the Ministry of Household Affairs. The officials are responsible, why do we, the practitioners, need to do it?"

At first, under the influence of anxiety, Mo Li felt that this was the national master's favoritism towards Gu Xu - because Gu Xu was good at improving talismans. Seal script, so the National Master specially set up such a link to help Gu Xu become the final winner.

But then he thought that the Imperial Master had always been recognized as an upright figure by Luojing officials. Not only was he impartial and unfaithful, but he had even contradicted the emperor in his youth - he had never He will not hide his appreciation for outstanding talents, but he will never abuse his power to change the rules for his own selfish gain.

It is obviously an incorrect idea to question the integrity of the national preceptor because he cannot solve the problem at hand.

Mo Li sighed.

Under such circumstances, he could only silently admit that his knowledge of talismans and seal scripts was still lacking after all.

For example, "eye-pointing and soul-enhancing" are relatively unconventional talismans that do not exist in orthodox books... If he had known about it before, he would not be as helpless as now.

…………

Shen Qiu also stared at the white paper in front of him, unable to do anything.

During this period just now, he tried to use the spell of "turning runes into real objects". He drew a complex rune on white paper, turned it into an abacus, and then While fiddling with the beads on the abacus, he recorded the calculation results.

But the national preceptor soon appeared in front of him and stopped his move.

The Imperial Preceptor thought that this was a trickLittle clever behavior.

After all, the abacus is just a tool.

In the final analysis, he still uses his own brain.

So Shen Qiu sighed.

He looked at the young man in black lying on the floor, wringing his fingers, and then at Gu Xu, who was writing furiously next to him, and he felt increasingly anxious.

Only Mo Li, who was sitting at the desk with a sad face like him, could give him some psychological comfort.

…………

Gu Xu lowered his head, thinking, and drafting on paper.

"Luoshui Conference...expenditure...calculation...talisman skills...quickly..." Key words buzzed one after another, like countless bees flying by his ears. .

The memories of the two lives were intertwined and gathered into countless thoughts, setting off a storm in his mind.

He first thought that if he had a computer in front of him, he could easily solve this problem by writing a piece of code or using an Excel spreadsheet.

However, it is obviously unrealistic to build a computer from scratch.

After hundreds of years of development and evolution, computers in previous generations have developed extremely complex structures and functions.

Gu Xu was just an ordinary college student before traveling through time. It was impossible for him to completely understand the principles, let alone use the talismans of this world to realize it.

Most of the talismans in this world are used for fighting, exorcising ghosts or warding off evil spirits. Even if there are a few functional talismans, such as "wind talisman", "cold protection talisman", etc., their uses are very single.

But when Gu Xu thought about it, he didn't need to build a computer with complex functions today.

No need to display the screen, no need to play sound, no need to connect to the Internet, no need to store videos...

Just the simplest digital calculation function is enough.

Even just addition and subtraction are required - after all, continuous and repeated calculations of addition are the common way modern computers do multiplication and division.

The first thing Gu Xu thought of was the Pascal adding machine.

The father of French mathematician Pascal was a tax official. Because Pascal had witnessed his father struggling to calculate tax rates when he was a child, he wanted to do something for his father.

The "Pascal Adder" is a device composed of a series of gears. It looks like a rectangular box. It needs to be tightened with a key before it can rotate. It can only perform addition and subtraction.

In order to solve the carry problem of "adding ten to one" in addition, Pascal used a small claw-type ratchet device. When the positioning gear rotates towards 9, the pawl gradually rises; once the gear rotates to 0, the pawl falls down with a "click", pushing the ten-digit gear forward one gear.

But Gu Xu thought for a moment and felt that it was not easy to use the talismans of this world to present decimal numbers.

So he thought of the past lifeAnother mathematician, Leibniz from Germany.

Legend has it that one day in the 18th century, Leibniz's friend gave him a "Yi Tu", also known as the "Bagua Diagram". When looking at the Bagua diagram, Leibniz discovered that each hexagram is composed of two symbols: "yin" and "yang". He got inspiration from it and took the lead in systematically proposing the binary algorithm.

Gu Xu didn’t know whether this rumor was true or false.

However, the moment he thought about this, it was as if a bolt of lightning flashed across the dark night sky, and the rumble of thunder broke the deathly silence.

He sat up suddenly and his eyes lit up.

"I know!" he thought to himself.

He knows that the reason why computers in previous generations used binary counting is because they are composed of logic circuits. There are usually only two states in the circuit, the switch is on and off. It can be represented by "one" and "zero".

In this world, all formations related to Bagua are also based on Yin and Yang.

Yin Yao is represented by two short lines ("--"); Yang Yao is represented by one long line ("-").

You can use them to replace the numbers "zero" and "one".

After the two rituals, there are four images -

The two yin lines are "Taiyin", the upper yang and lower yin are "Shaoyang", and the upper yin and lower yang are "Shao Yang" "Yin", and the two Yang Yao are "Sun".

Can be used to replace "00", "01", "10" and "11" in binary numbers.

After that, the Four Symbols gave birth to the Eight Diagrams, the Eight Diagrams transformed all things, and all things became the world...

Gu Xu is not only well versed in the art of spells, but also has a deep knowledge of the deduction of the Eight Diagrams. learn.

He felt that he could use the Yin and Yang Bagua to design a set of talisman arrays that could be used for addition and subtraction calculations.

Thinking of this, he grabbed the slender pen on the table, dipped it in ink, and quickly drew runes one after another on the paper.

…………

Outside the house.

The big shots are still waiting quietly in the pavilion surrounded by vegetation.

As one of the deputy examiners, Fu Tao, a professor at the academy, naturally has an understanding of the examination questions raised by the national teacher.

After being silent for a long time, he finally couldn't restrain his curiosity and couldn't help asking the Imperial Preceptor: "Master Imperial Preceptor, why do you put such a test on the candidates?

“We usually use talismans to drive away ghosts and defeat enemies. Things like calculating the expenses of the Luoshui Conference can be completed by officials from the Ministry of Revenue——"

"——This is just a small attempt," the Imperial Master smiled and said He cut off his words and said, "My master Chiyangzi once put forward a point of view during his lifetime. The techniques of talisman and seal script can not only be used in the battles of practitioners - if they are developed properly, they may also be promoted to the common people and used in battles." to improve people’s livesdaily life.

"Decades ago, Master once tried to carve a set of talismans on the 'Qu Yuan Plow' so that it could plow the fields automatically without the help of manpower or livestock. Breaking up soil and plowing trenches will make it easier for farmers to farm.

“But it has some obvious limitations - it needs. Practitioners regularly inject a large amount of true energy into the formation to maintain normal operation.

"Unfortunately, the master passed away early and was unable to fully put his ideas into practice.

"And I am not talented enough to have the bold imagination of the master. ; Although my junior brother He Yiqun is smarter than me, he is a carefree and pleasure-seeking person and has no interest in this kind of thing.

"So, I can only place my hope on the descendants of the Daqi Dynasty - maybe among them, there is a person with both talent and ambition who can step forward and inherit the master's legacy. "Unfinished business."

Fu Tao stopped talking.

In the understanding of Fu Tao and most monks in the Daqi Dynasty, practitioners and mortals have their own duties. The former is responsible for killing demons and is the sword that protects the country; the latter is the country's sword. The backbone of the country maintains the daily operations of the country.

The two are in harmony with each other.

Chi Yangzi didn’t use talismans to kill ghosts, but thought about how to use talismans to farm the land. Fu Tao thought it was a bit unprofessional.

However, the moment she heard the Imperial Master’s words, Princess Zhaoning next to her suddenly straightened her back and her eyes lit up.

Fu Tao has been staying in Longmen Academy for a long time, having no worries about food and clothing, and not caring about worldly affairs. Naturally, he does not understand the current national conditions of Da Qi Dynasty.

But Princess Zhaoning is different.

As the person in charge of the secular power of the Daqi Dynasty, she knew that many places in the country were actually short of food resources, and she also knew that many places were plagued by ghosts, causing casualties and injuries, and leaving the fields uncultivated.

The grain collected by the national treasury is getting less and less year by year, but Princess Zhaoning cannot think of a good solution.

Coupled with the long night, the ghosts and monsters in the entire wilderness will become stronger and more terrifying...

Princess Zhaoning has always been very worried about whether the Daqi Dynasty can Survive this disaster smoothly.

But today, Da Qi’s Imperial Master’s words gave her a new idea.

She felt that she might try to use the power of practitioners to solve secular people's livelihood problems.

"It's just...are there any practitioners willing to help me do these things?" Thinking of this, Princess Zhaoning couldn't help but frown again.

On the surface, she seems to have a high position of power, holding the supreme power of "approving red" instead of the emperor.

But in fact, she is just a tool to handle government affairs - all her power comes from the emperor, and she has no power of her own.

She wanted to give orders to her mortal courtiers,All must rely on the name of Emperor Tianxing, let alone ordering practitioners with transcendent status.

"Perhaps, I will have to find an opportunity to talk to the National Preceptor in the future?" She thought silently in her heart.

…………

Inside "Siqi Hall".

Shen Qiu quietly turned his head and glanced at Gu Xu, who was sitting next to him.

Half an hour later, Gu Xu had drawn a very complicated formation on the paper, which was covered with dense "Yin Yao" and "Yang Yao".

In Shen Qiu's opinion, the appearance of this talisman array is very ugly. Not only is it asymmetrical, but the lines connecting the various hexagrams are messy, like a mess.

It was different from all the formations Shen Qiu had seen before.

As Gu Xu injected real energy into the formation, these lines shone with colorful light, which was dazzling.

"What is he doing?" Shen Qiu frowned slightly.

However, Shen Qiu didn't spend too much time pondering Gu Xu's thoughts.

Because he also found his own way of thinking.

As one of the richest families in the world, the Shen family of Jinling owns numerous properties. In recent years, as the younger generations of the family have grown up, they have gradually taken over from their elders and assumed the responsibility of managing these industries.

Of course, an unpopular bastard like Shen Qiu is not worthy of running the family business independently; more often than not, his identity is the personal assistant of his brother Shen Hua - who usually hides behind the scenes to help others. Shen Hua made suggestions; when Shen Hua went out to visit the brothels, she went to help him discuss business.

His inspiration came from the array diagram on Gu Xu's paper, and also from the "calculation chips" that accounting gentlemen would use before abacus became widely popular.

"Shuangchi" is a series of small sticks of the same length and thickness, generally 13 to 14 centimeters in length, mostly made of bamboo. About 270 sticks are placed in a bunch. In a cloth bag. When you need to count, just take them out and play with them on the table, kang or on the ground.

According to the calculation rules, the counting method is as follows: vertical format for units, horizontal format for tens, vertical format for hundreds, horizontal format for thousands, and horizontal format for tens. Use vertical expressions and so on, so that from right to left, vertical and horizontal alternate, and so on, you can express any large natural number.

"Although I can't understand Master Gu's formation, I can probably guess that he uses the idea of ​​'breaking the whole into parts' and 'turning the complex into simple'," Shen Qiu secretly said I thought, "After all, I can understand every tiny component of his formation - but when they are connected together, I can't understand it."

"Maybe, I can Try to use a similar idea and use horizontal and vertical strokes to simulate calculations to represent each number in the file. Then learn from the principles of the illusion magic circle and follow the rules of operation to let these strokes change on their own according to specific rules.

"In this way, I only need to record the final pattern of the formation,You will get the result. "

Thinking of this, Shen Qiu was ecstatic and thought, "I am really a genius." At the same time, he grabbed the brush on the table and began to draw the formation diagram quickly.

Now , he is already half an hour behind Gu Xu and Zhao Xinran.

If he doesn't hurry up, he will definitely be left far behind.

Another half hour later, Gu Xu suddenly stood up from his seat.

The formation diagram he drew shone brightly on the table.

Everyone's eyes fell on him - whether it was Shen Qiu who was writing furiously, Mo Li who was sitting in a chair in a daze, or Zhao Xinran who was earnestly teaching the little boy in black arithmetic, they couldn't help but widen their eyes. His eyes were broken.

“This person... won’t figure out the result so quickly, right? ”

An incredible idea came to their minds.

At this moment, Zhao Xinran said that the progress was not over halfway, and Shen Qiu had just started to draft on paper. .

Gu Xu’s move stopped their thoughts for a moment.

The next second, Da Qi Imperial Master suddenly appeared beside Gu Xu, confirming their thoughts. Guess.

"Have you figured out the result? "The Imperial Master looked at Gu Xu with a smile.

Gu Xu nodded and pointed to the formation diagram on the table: "Please take a look at it, Imperial Master. ”

The brilliant light intertwined and changed on the paper, and then converged into a number, which was presented in front of the Imperial Preceptor.

The Imperial Preceptor knew that this was the correct answer.

However, even with his knowledge as a Fu Dao master, he cannot fully understand the operating principle of Gu Xu's formation.

He really can't understand why Gu Xu can rely on a series of methods. The Yin and Yang hexagrams are used to calculate the expenses of the "Luoshui Conference"

"Can you go out and tell me its principles? "The Imperial Master nodded slightly and said to Gu Xu in a tone of asking for advice.

"A capable person is a teacher", this is the view that the Imperial Master has always believed in.

As long as you can learn When he learns new knowledge and skills, he is never ashamed to ask others for advice - even if others are much younger than him and have a much lower status than him, he will still ask his questions in a humble manner.

"No problem. "Gu Xu smiled and nodded.

Then, Gu Xu followed the Imperial Master and left the "Siqitang".

The remaining people looked at Gu silently Xu's leaving figure looked at each other in silence.

…………

A few minutes ago, Shen Qiu was holding a brush, eager to show off his skills. However, Gu Xu and. The Imperial Master's conversation seemed to pour cold water on his head, extinguishing the fire of passion that had finally burned within him.

"I...I still need to continue painting. thisDamn it? ”

Shen Qiu suddenly felt that what he was doing was meaningless.

There was only one winner in the end.

Now Gu Xu is far ahead .

No matter how hard he tried, he would never have a chance to catch up with Gu Xu.

At this time, he suddenly understood why the national master had shown such obvious behavior towards Gu Xu. - When such an outrageous genius appears in the world, it’s hard not to pay more attention to him.

“Forget it, let’s just finish it! " Shen Qiu thought for a while, sighed helplessly, then lowered his head and continued to draw the talisman array, "Although I am not as good as that monster, I finally came to Longmen Academy from Jinling... What if I give up easily? Didn't he become the laughing stock in the eyes of those in the family again? "

…………

Zhao Xinran took a deep breath.

In her calm and indifferent eyes, there was finally a trace of emotion.

She glanced at the boy in black beside her, as if looking at a son who was failing.

The boy in black raised his head, his eyes looking very innocent.

p>

“What are you looking at me for? "Zhao Xinran pointed to the documents on the ground and shouted sternly, "Hurry up and figure it out for me! ”

The expression of the boy in black suddenly became extremely painful.

…………

As for Mo Li, his eyes were dazed, and he almost doubted that he was Dreaming.

He has already finished the entire formation before he even started writing.

How did that guy Gu Xu do it? Is he really a normal person?

......

At the same time, Gu Xu followed the national master to a room. The room was empty.

They sat down on both sides of a table facing each other.

Then, Gu Xu followed the Imperial Master’s request and began to explain his design to him. The principle of the talisman array.

"Master Imperial Master, I use the symbols of 'Yin Yao' and 'Yang Yao' to represent the numbers '0' and '1' on this talisman array," Gu Xu explained while pointing to a certain place on the array diagram, "Look, these three symbols form a triangle. If both bottom corners are "Yang Yao", then the top corner will automatically become "Yang Yao"; otherwise, the top corner will appear "Yin Yao".

"This component, I call it the 'AND gate'."

"And gate..." The national master recited the word silently, feeling a little confused.

However, he still said to Gu Xu: "You continue."

At this time, Gu Xu reached out and pointed to another triangle: "This triangle pattern is similar to the one just now. There is a slight difference - as long as one bottom corner shows a 'Yang Yao', then its top corner will also become a 'Yang Yao'; if both bottom corners are 'Yin Yao', then the top corner will become a 'Yang Yao' 'Yin Yao'

"I call it the 'OR gate'.

"Also, these two symbols are connected by a straight line - the left is the 'Yin Yao', and the right is the 'Yang Yao'; The left side is the 'Yang Yao', and the right side will be the 'Yin Yao'. The two are always opposite.

"I call it the 'not gate'."

Next, Gu Xu also introduced the "NAND gate", "NOR gate", and "XOR gate" etc.

Finally, he described to the National Master that using these components, a simple "adder" can be constructed to perform simple addition operations; if you want to perform more complex operations with more digits, Just combine these "adders" together and use them.

The Imperial Master was silent for a long time, then looked up at him: "Gu Xiaoyou, can you say it again?"

PS: Sorry, maybe because I stayed up all night a few days ago, Pudding's recent state It's very bad. I feel dizzy every day. I'm very stuck on Kawen. I haven't finished writing it until now. I may need to adjust it in a few days, but I will keep a minimum of 4k words per day (equivalent to the previous two free chapters). If the situation is better, I will add more chapters!
