However, Gu Xu quickly dismissed this idea.
On the one hand, the intelligence quotient of the characters created by the technique of "enhancing the eyes and soul" is really limited.
The brain of this little boy in black is probably equivalent to that of a ten-year-old mortal child - at this moment, under the guidance of Zhao Xinran, he is flipping through documents and scribbling on white paper; occasionally He would make a few miscalculations, and Zhao Xinran would point it out sternly.
"As expected of arithmetic, even the paper man will have 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 less 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 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 an assessment content," Mo Li scratched his head and thought distractedly, "Officials from the Ministry of Household Affairs are responsible for estimating the expenses of the Luoshui Conference, so why do we need to Are these practitioners going to do it?”
At first, under the influence of anxiety, Mo Li felt that this was the national master's partiality towards Gu Xu - because Gu Xu was good at improving talismans and seals, 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 by the Luojing officials as an upright person. Not only was he impartial and indifferent, but he had even contradicted the emperor in person when he was young - he would never hide his love for outstanding talents. Appreciate it, but he will never abuse his power to change the rules for his own selfish gain.
It is obviously an incorrect thought 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 admit silently that his knowledge of talisman and seal script was still lacking after all.
Such relatively unconventional talisman seal scripts as "Pointing Eyes and Energizing Spirits" that do not exist in orthodox books... If he had known about it before, he wouldn't be as helpless as he is now.
…………
Shen Qiu also stared at the white paper in front of him, unable to do anything.
During this period of time just now, he had tried to use the spell of "turning runes into real objects", drawing a complex rune on the white paper, turning it into an abacus, and then fiddled with the beads on the abacus. , while recording the calculation results.
But the national master soon appeared in front of him and stopped his move.
The Imperial Preceptor thought that this was a clever act on his part.
After all, the abacus is just a tool.
After all, he still uses his own brain.
Then 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, building a computer from scratch is obviously unrealistic.
After hundreds of years of development and evolution, computers in previous generations have developed extremely complex structures and functions.
Before Gu Xu traveled through time, he was just an ordinary college student. It was impossible to fully 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.
However, Gu Xu thought about it and realized that he did not need to build a computer with complex functions today.
There is no need to display images, play sounds, connect to the Internet, or store videos...
All you need is the simplest number-crunching capabilities and you're good to go.
Or even just add and subtract - after all, continuous and repeated calculations of addition are the way modern computers usually do multiplication and division.
The first thing Gu Xu thought of was the Pascal adding machine.
The father of the 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.
"Pascal's adding machine" 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 do 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.
Then he thought of another mathematician in his previous life, Leibniz from Germany.
Legend has it that one day in the 18th century, Leibniz's friends gave him a "Yi Tu", also known as "Bagua Tu". When looking at the Bagua chart, 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 like 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 knew that the reason why computers in previous generations used the binary counting method was because they were composed of logic circuits. There were usually only two states in the circuit, the switch on and off. These two states could be represented by "one" and "one". "Zero" means.
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 ("—").
They can be used in place of the numbers "zero" and "one".
After the two rituals, there are the four images——
The two yin lines are called "Tai Yin", the upper yang and lower yin are called "Shaoyang", the upper yin and lower yang are called "Shaoyin", and the two yang lines are called "Taiyang".
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 turned into 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 understanding of Bagua deduction.
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 were still waiting quietly in the pavilion surrounded by vegetation.
Academy teacher Fu Tao, as one of the deputy examiners, naturally understands the examination questions raised by the national master.
After being silent for a long time, he finally couldn't restrain his curiosity and couldn't help but ask the National Preceptor: "Master National Preceptor, why do you put such a test on the candidates?
"We use talismans on daily basis to drive away ghosts and defeat enemies. Things like calculating the expenses of the 'Luoshui Conference' are done by officials from the Ministry of Household Affairs——"
"——This is just a small attempt," the national master smiled and interrupted him, "My master Chiyangzi once put forward a point of view during his lifetime. The art of talisman and seal script can not only be applied to practitioners. In the battle - if developed properly, they may be promoted to the private sector and used to improve people's daily lives.
"Decades ago, Master once tried to carve a set of talismans on the 'Qu Yuan Plow', so that it could automatically plow the fields, break up the soil, and plow out grooves without the help of manpower and livestock. Ditch. With such equipment, it will become easier for farmers to farm.
"But it has some obvious limitations - it requires practitioners to regularly inject a large amount of true energy into the formation to maintain normal operation.
“Unfortunately, Master passed away early and was unable to fully put his ideas into practice.
"But I am dull in nature and do not have the bold imagination of my 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 unfinished work of Master."
Fu Tao stopped talking.
In the understanding of Fu Tao and most monks in the Daqi Dynasty, practitioners and mortals each perform their own duties. The former is responsible for killing demons and is the sword that protects the country; the latter is the backbone of the country, maintaining the country's power. daily operations.
The water in the two wells does not interfere with the water in the river.
Chiyangzi didn't use talismans to kill ghosts, but thought about how to use talismans to farm the land. In Fu Tao's opinion, 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. She also knew that many places suffered from ghost disasters, resulting in casualties and uncultivated fields.
The grain collected by the national treasury is getting less and less year by year, but Princess Zhaoning can't think of a good solution.
Coupled with the arrival of 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 successfully survive this disaster.
But today, the words of Grand Master Daqi 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 authority, holding the supreme power of "approving the red" instead of the emperor.
But in fact, she was just a tool to handle government affairs - all her power came from the emperor, and she had no power of her own.
If she wants to give orders to mortal courtiers, she must use the name of Emperor Tianxing, let alone give orders to practitioners with transcendent status.
"Perhaps I have to find an opportunity to talk to the Imperial Master in the future?" She thought silently in her heart.
…………
Inside "Siqitang".
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 was very ugly. Not only was it asymmetrical, but the lines connecting the various hexagrams were messy, like a mess.
It was different from all the formations Shen Qiu had seen before.
As Gu Xu injected true 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.
The Shen family of Jinling is one of the richest families in the world, with numerous properties under its name. 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 his brother Shen Hua's personal assistant - he usually hides behind the scenes to advise Shen Hua; when Shen Hua When you go out to visit the brothel, go 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. There are about 270 sticks in a bunch and placed 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 rules of calculation, the calculation method is as follows: use vertical format for units, horizontal format for tens, vertical format for hundreds, horizontal format for thousands, vertical format for tens of thousands, etc., so From right to left, vertically and horizontally, and so on, any large natural number can be represented.
"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 simplicity'," Shen Qiu thought to himself, "After all, I I can understand every tiny component of his formation - but when they are connected together, I can't understand it.
"Perhaps, I can try to use a similar idea and use horizontal and vertical strokes to simulate calculations to represent each number of the file. Then I can learn from the principles of the illusion magic circle and follow the rules of calculation to let these strokes automatically follow specific rules. changes occur.
"In this way, I only need to record the final pattern of the formation to 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 was already half an hour behind Gu Xu and Zhao Xinran in terms of progress.
If we don't seize the time, we will definitely be left far behind.
…………
After another half an hour, 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. eyes.
"This person... won't figure out the result so quickly, right?"
An incredible idea came to their mind.
At this moment, Zhao Xinran said that the progress was not over half yet, 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 next to Gu Xu, confirming their guess.
"Have you calculated 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 national master.
The Imperial Master knew that this was the correct answer.
However, even with his knowledge as a Fu Dao master, he could not fully understand the operating principle of Gu Xu's formation.
He really couldn't understand why Gu Xu could calculate the expenses of the "Luoshui Conference" based on a series of yin and yang hexagrams.
"Would you mind going out and telling me how it works?" The Imperial Master nodded slightly and asked Gu Xu for advice.
"A capable person is a teacher", this is the view that national teachers have always firmly believed.
As long as he can learn 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.
Perhaps it is precisely because of his style that, although he only has mediocre "Fifth Grade" qualifications, he can become a master of Fu Dao and rank among the saints.
"No problem." Gu Xu smiled and nodded.
Afterwards, Gu Xu followed the imperial master and left the "Siqitang".
The few remaining people silently watched Gu Xu's leaving figure, silently caring about each other.
…………
A few minutes ago, Shen Qiu was holding a brush, eager to show off his skills. However, the conversation between Gu Xu and the Imperial Master seemed to pour a basin of cold water on his head, instantly extinguishing the flame of passion that had finally burned within him.
"I...do I still need to continue drawing this damn formation diagram?"
Shen Qiu suddenly felt that what he was doing was meaningless.
There is 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 Imperial Master had shown obvious partiality towards Gu Xu before - when such an outrageous genius appeared in the world, it was difficult not to pay more attention to him.
"Forget it, let's continue to 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 here from Jinling. A trip to Longmen Academy...if I give in easily, wouldn’t I become a 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 next to her, as if looking at a son who failed to live up to expectations.
The boy in black raised his head, his eyes looking very innocent.
"Why are you looking at me?" Zhao Xinran pointed at the documents on the ground and shouted, "Why don't you 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 suspected that he was dreaming.
He hasn't started writing yet.
Others have already figured out the entire array.
That guy Gu Xu...how on earth did he do it? Is he really a normal person?
…………
at the same time.
Gu Xu followed the imperial master and came to an empty room.
They sat across from each other at a table.
Afterwards, Gu Xu followed the Imperial Master's request and began to explain to him the principles of the talisman array he designed.
"Master Imperial Master, I use the symbols of 'Yin Yao' and 'Yang Yao' on this talisman array to represent the numbers '0' and '1'," Gu Xu explained while pointing to a certain number on the array diagram. One place, "Look, these three symbols form a triangle. If the two base corners are 'Yang Yao', then the top corner will automatically become 'Yang Yao'; in other cases, the top corner will be Will show 'yin Yao'.
"This component, I call it the AND gate."
"With the door..." The national master recited this 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 slightly different from the one just now - as long as one of the bottom corners shows a 'Yang Yao', then its top corner will also become a 'Yang Yao' Yao'; if the two bottom corners are both Yin Yao, then the top corner will become Yin Yao.
"I call it the OR gate.
"Also, these two symbols are connected by a straight line - if the left is 'Yin Yao', the right will be 'Yang Yao'; if the left is 'Yang Yao', the right will be 'Yin Yao'. The two are always opposite. .
"I call it the NOT gate."
Next, Gu Xu also introduced the "NAND gate", "NOR gate", "XOR gate" and so on.
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 digits and more complex operations, you only need to add these "adders" ” Just use them together.
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 is in very bad shape recently. His head feels dizzy every day, and Kawen is very stuck. 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!
