Chapter 246 Gu Xu’s Lenovo (two-in-one)
However, Gu Xu quickly ruled out 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 young 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 was looking at documents and scribbling on white paper. Tu Huahua; occasionally he would miscalculate a few numbers, which Zhao Xinran pointed 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 Preceptor would propose such assessment content,” Mo Li scratched his head and thought distractedly, “Estimating the expenditure of the Luoshui Conference is something that officials from the Ministry of Revenue have to do We are responsible, why do we need practitioners to do it?”
At first, under the influence of anxiety, Mo Li felt that this was the national master’s preference for Gu Xu-because Gu Xu was good at improving seal scripts. Therefore, the National Master specially set up such a link to help Gu Xu become the final winner.
But then he thought that the Imperial Preceptor had always been recognized as an upright figure by Luojing officials. Not only was he impartial and impartial, but he had even contradicted the emperor to his face when he was young - he never He will 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 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 as "pointing eyes and soul", which are relatively unconventional and 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 of time just now, he had tried to use the magic 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.
In the final analysis, 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 making a draft on the 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, then he could write a piece of code or use an Excel spreadsheet to easily solve this problem.
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.
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.
But Gu Xu thought about it and realized that he did not 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...
Only the simplest digital calculation function is required.
Or even just add and subtract - after all, continuous and repeated calculations of addition are the way modern computers 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.
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 another mathematician in his previous life, Leibniz from Germany.
Legend has it that one day in the 18th century, a friend of Leibniz gave him a "Yi Tu", also known as the "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 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 knew that the reason why computers in previous generations used binary counting 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 were exactly the same. Can be represented by "one" and "zero".
In this world, all formations related to Bagua are also based on Yin and Yang.
The Yin Yao is represented by two short lines ("--"); the Yang Yao is represented by a long line ("—").
They can be used in place of the numbers "zero" and "one".
After the two rituals, there are four images -
The two yin lines are "Taiyin", the upper yang and the lower yin are "Shaoyang", and the upper yin and lower yang are "Shaoyin" , the two yang lines are "sun".
Can be used to replace "00", "01", "10" and "11" in binary numbers.
After this, the Four Symbols gave birth to the Bagua, the Bagua 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 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.
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 but ask the Imperial Preceptor: "Master Imperial Preceptor, why do you put such a test on the candidates?
< br>“We use talismans and seals on daily basis to drive away ghosts and defeat enemies. Things like calculating the expenditure of the 'Luoshui Conference' can be completed by officials from the Ministry of Household Affairs——"
"——This is just a small attempt," the Imperial Master smiled and interrupted He said, "My master Chi Yangzi once put forward a point during his lifetime that 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 people for use. 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 pour water into the formation regularly. A large amount of real energy can 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; junior brother Although 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 legacy of Master. A finished undertaking.”
Fu Tao stopped talking.
In the understanding of Fu Tao and most of the 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 maintains the daily operation of the country.
The two are not in conflict with each other.
Chiyangzi doesn’t use talismans to kill ghosts, but thinks about how to use talismans to farm the land. In Fu Tao’s opinion, it’s a bit unprofessional.
However, the moment she heard the words of the Imperial Master, 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 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 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 power, holding the supreme power of "criticizing 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 issue orders to mortal courtiers, she must use the name of Emperor Tianxing, let alone ordering practitioners with transcendent status.
"Perhaps I will 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 is very ugly. Not only is it asymmetrical, but the lines connecting the various hexagrams are messy, like a mess.
It is different from all the formations Shen Qiu has 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.
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 - usually hiding behind the scenes to help 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, usually thirteen to fourteen centimeters in length, mostly made of bamboo. About two hundred and seventy 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 rules of calculation, the expression method of calculation and counting is: vertical format for units, horizontal format for tens, vertical format for hundreds, horizontal format for thousands, and horizontal format for tens of thousands. Vertical expression and so on, so from right to left, vertical and horizontal alternating, and so on, any large natural number can be expressed.
"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. Said, "After all, 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 is to 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 to get the result."
Thinking of this, Shen Qiu was ecstatic and thought, "I am such a genius"; at the same time, he grasped He picked up 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 in terms of progress.
If we don’t hurry up, 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 shines brightly on the table.
Everyone’s eyes fell on him - whether it was Shen Qiu who was writing rapidly, or Mo Li who was sitting in a chair in a daze, or Zhao who was teaching the little boy in black arithmetic with all his heart. Xinran couldn't help but open his eyes.
"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 half yet, and Shen Qiu had just started to draft on paper.
Gu Xu’s move made their thoughts stagnant 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 map on the table: "Please take a look at it, the 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 knows that this is 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 was able to calculate the expenses of the "Luoshui Conference" with a series of yin and yang hexagrams.
"Can you go out and tell me how it works?" The Imperial Master nodded slightly and said to Gu Xu in a asking tone.
"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 for advice with a humble attitude. own questions.
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.
Then, 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?"
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 preference for 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'm not as good as that monster, I'm better I just came to Longmen Academy from Jinling... If I give up easily, won't I become a laughing stock in the eyes of those in the family?"
…………
Zhao Xinran took a deep breath.
In her calm and indifferent eyes, there was finally a trace of emotion.
She glanced at the young boy in black beside 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 sternly, "Hurry up and figure it out for me!"
The expression of the boy in black suddenly became particularly 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 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.
Subsequently, 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 as he stretched out his hand Pointing to a certain place on the array diagram, "Look, these three symbols form a triangle. If the two bottom corners are 'Yang Yao', then the top corners will automatically become 'Yang Yao'; other In this case, the top corner will appear as a 'Yin Yao'
"This component, I call it the 'AND gate'. "
"With the Gate..." The Imperial Master recited this word silently, feeling a little confused.
But 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 there is one If the 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 '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 show '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 Preceptor 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 These "adders" need to be combined 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 of staying up all night a few days ago, Pudding is in poor condition recently. , my head feels dizzy every day, Kawen is very stuck, and 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!
