"Your Majesty, this is an abacus formula. You only need to memorize it backwards and forward, and use an abacus to calculate additions and subtractions. No matter how huge the numbers are, you can quickly calculate the results, which is convenient and fast."
Sitting in the spacious and bright office, Fang Xuanling introduced the abacus and abacus formula to His Majesty Li Er, and called two children to demonstrate on the spot for His Majesty Li Er.
"These two children are students in the school and learn quickly. Your Majesty might as well give them an arithmetic question to test them and test the magic of abacus."
His Majesty Li Er naturally knows the abacus.
This calculation tool that Fang Jun made famous is still popular in the Tang Dynasty, but His Majesty Li Er, who is more concerned with state affairs, has never had a deep understanding of it. In his mind, it is just a calculation tool. Does it matter whether the calculation is faster or slower?
But this abacus formula was somewhat interesting, so I casually wrote a question on the paper: "One thousand and three thousand ninety-nine hundred and eighty-five plus twenty-one thousand one thousand seven hundred and four hundred and two minus eight thousand five hundred and thirty-one..." ..." He put down his pen and glanced at the two children who were obviously a little nervous. He felt that the children were too small and this question was a bit difficult, so he kindly said: "Slowly calculate, one stick of incense..."
Before he finished speaking, he saw two dolls, each with an abacus, crackling the beads of the abacus, but they said in unison: "Your Majesty, it is equal to twenty thousand seven thousand one hundred and nine Shilu."
His Majesty Li Er almost bit his tongue and his eyes widened...
How could it be so fast?
Such a complicated number, such a young child, if he can calculate the correct answer in a stick of incense, he would be considered amazing. Arithmetic problems are not difficult, but the difficulty is that huge numbers require patient calculations without making mistakes, but it only takes a blink of an eye. What happened to Kung Fu?
A child with such a small age wouldn't have the guts to fool me...
His Majesty Li Er had a look of surprise on his face and did not hesitate to calculate it himself. He turned around and asked Fang Xuanling: "Ai Qing, is it correct?"
Fang Xuanling himself took an abacus and calculated it, and said with a smile: "It's correct."
His Majesty Li Er patted his thigh excitedly and praised: "Good stuff! If you have an abacus and this set of abacus formulas, you will be able to save a lot of time and improve the accuracy of the annual review and calculation of the Ministry of Household Affairs. This is rare." ,rare……"
This is indeed good stuff.
But while he was talking, he saw two little babies and couldn't help but curl his lips...
His Majesty Li Er asked curiously: "What, you two think I am wrong?"
The two little babies, one thin and frail, the other sculpted and polished, felt a little scared when facing His Majesty the Emperor. The same smart eyes looked at each other, and finally the little girl got the courage to bow and salute like an adult, and said nonchalantly: "In reply to Your Majesty... In fact, when the teacher usually teaches us arithmetic exercises, They were all taken from the Taishi Bureau, and the movements of the sun, moon and five stars were calculated according to the ecliptic degrees..."
His Majesty Li Er was surprised and couldn't help but blush.
People usually calculate astronomical calendars, but I gave a really bad addition and subtraction question...
Looking up to the sky and laughing to hide his embarrassment, His Majesty Li Er expressed sincere admiration to Fang Xuanling: "Aiqing is indeed a scholar of heaven and man. He is able to develop such a set of abacus formulas and teach such outstanding students. I really admire him." Endless."
Fang Xuanling said with a smile: "Your Majesty, the abacus formula was invented by my incompetent Erlang. In fact, it has been around since the abacus was invented, but it has never been promoted. As for these two dolls, they are not the disciples of the old minister. The one who taught them arithmetic was Tai Shi Cheng Li Chunfeng."
His Majesty Li Er was stunned, and said with a wry smile: "Your stick is really... talented!"
What more can be said?
As for Fang Jun's unparalleled ability in invention and creation, even the world's most powerful person would have to express his admiration!
At this time, Cheng-Zhu Neo-Confucianism had not yet been born, and the social form in which all people were inferior and only those who were good at reading had not emerged. Even Confucian students were not limited in their knowledge of classics and ignorant of worldly affairs, and their pragmatic atmosphere was more intense. Therefore, few people open their mouths and talk nonsense about "fantastic skills and ingenuity". Generally speaking, some inventions and creations that can improve the national economy and people's livelihood are treated positively.
It's just that His Majesty Li Er felt a little embarrassed.
A few days ago, I was bent on demoting Fang Jun out of Beijing, but now I have to praise him...
"Both of you were servants of the Fang family?"
His Majesty Li Er avoided embarrassment and asked Wenyan about the two dolls. In fact, he was indeed delighted with the intelligence of the two dolls.
The two dolls quickly replied: "Student Di Renjie, a person from Bingzhou, the ancestor of the family, Zuocheng Di Xiaoxu."
"A student from Wuzhou, my father is Luo Luyuan, the magistrate of Bochang County."
His Majesty Li Er couldn't remember which Li Er Luo Luyuan was, but the Wuzhou Luo family had never heard of him, so he was obviously not a member of aristocratic family. Di Xiaoxu had just taken up the post of Minister Zuocheng not long ago, so His Majesty Li Er naturally knew about it.
He couldn't help but sigh: "They all come from poor families and are smart and handsome. It's rare to find them."
He most likes to see children from poor families have a promising future. Because he was born in a poor family, he knows how to work hard and become more conscientious after becoming an official. He is not like the playboys of children from aristocratic families who only care about their own selfish interests and ignore the great interests of the empire.
With joy in his heart, His Majesty Li Er pulled off a pair of Tuanlong jade pendants from his waist and said happily: "I will reward you two with something to carry with you. It is not only a reward for your intelligence, but also an encouragement to you. The two of you must not be complacent. You must continue to work hard and be able to receive careful guidance and cultivation from the Prime Minister. Not many people in this world are so lucky. When you two grow up and take part in the imperial examination, I will be in the Tai Chi Hall and hand-picked with Zhubi. , watching you wait for your hairpin and flowers to parade through the streets astride a horse!"
The two children's faces turned red with excitement. They carefully accepted the emperor's reward and said in unison: "Di Renjie (King Luo Bin) will definitely live up to His Majesty's expectations!"
His Majesty Li Er laughed loudly and waved his hand for the two of them to retreat.
Silence fell in the room.
Fang Xuanling looked at her nose and heart, holding a tea cup in her hand with a calm expression and silent.
His Majesty Li Er was a little unsure of how to speak...
He is a heroic man of a lifetime, tough-minded, wise and mighty. In his eyes, only the great Tang Dynasty will last forever. No matter who stands in front of this premise, he can be sacrificed.
But he is also a man of loyalty. How can he not have feelings for his old friend who followed him and rushed out of the mountain of corpses and blood to fight for his life?
Previously, he felt that the prince was not suitable for the position of crown prince, so he wanted to get rid of Fang Jun, the most powerful humerus around the prince. This was a national matter. Even if Fang Jun had outstanding achievements and even if Fang Jun was Fang Xuanling's son, Li Your Majesty will not hesitate.
But now facing Fang Xuanling, how could he not be apologetic?
Non-vegetation, ruthless Practice makes perfect……
After a moment of silence, His Majesty Li Er asked warmly: "Is your health ever better? After all, you are getting older, and proper self-cultivation is still necessary. You must not work day and night like you did in the past. Once your body is exhausted, wouldn't it be Make someone feel guilty?"
Fang Xuanling was ill at home. Although he seemed to be looking very good and not showing any signs of illness, His Majesty Li Er still spoke gently and sincerely.
Although everyone knows that Fang Xuanling is refusing to go to court by complaining of illness to euphemistically express his dissatisfaction with His Majesty Li Er's intention to demote Fang Jun out of the capital, or his strong opposition to His Majesty Li Er's desire to make Chu. …
But His Majesty Li Er was not angry at all.
Based on his friendship with Fang Xuanling and Fang Xuanling's achievements over the years, he is qualified to express his different political views to His Majesty Li Er.
Fang Xuanling said: "Thank you for your advice, Your Majesty. It's just that I was weak and contracted the wind and cold accidentally. It's not a serious problem."
His Majesty Li Er nodded and said: "Well, that's good. I'll ask the palace to send more nourishing things later."
"Thank you, Your Majesty."
Then, it became a bit quiet again...
After enduring it, His Majesty Li Er finally couldn't hold it back and said displeased: "You are so old, are you still getting angry with someone? Isn't this still not punishing Fang Jun after all? You don't have to do this. .”
Instead of calling her "Aiqing", she directly addressed her as "you", which seemed a bit rude, but in fact the atmosphere relaxed instantly.
After all, the fighting friendship for so many years was there, and Fang Xuanling had always been a selfless person. His Majesty Li Er didn't think it was a big deal if he occasionally lost his temper for the sake of the future of his descendants.
Fang Xuanling said calmly: "If the old minister had not complained of illness and refused to go to court, would Your Majesty have changed his mind? You know what the old minister is talking about is not about whether Fang Jun will be punished. In fact, the Fang family is bathed in the emperor's grace and holy favor. Youlong, the whole clan is grateful and grateful, even if His Majesty demotes Fang Jun to serve as a civilian, how can you dare to have the slightest bit of resentment?"
Your Majesty Li Er's face darkened.
He knew that Fang Xuanling was referring to Yi Chu...
However, this matter is a bone thorn in His Majesty Li Er's heart. How can it be changed so easily?
