"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. They learn very 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 kind of calculation tool, which was first introduced by Fang Jun, is still popular in the Tang Dynasty, but His Majesty Li Er, who is more concerned with state affairs, has not had a deep understanding of it. In his opinion, it is just a calculation tool. Can he calculate faster or slower?
A few, so what’s the big deal?
However, this abacus formula was somewhat interesting, so I casually wrote a question on the paper: "One thousand and three thousand nine hundred and eighty-five plus twenty-one thousand and one thousand seven hundred and four hundred and two and then subtract eight thousand and 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 equivalent to twenty thousand seven thousand one hundred ninety thousand pieces of land."
His Majesty Li Er almost bit his tongue and his eyes widened...
How can it be so fast?
For such a complicated number, if a child of such a young age can calculate it correctly and get the answer in just one stick of incense, that would be great. Arithmetic problems are not difficult, but the difficulty lies in the fact 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. He didn't feel ashamed to do the calculation 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: "What a good thing! If you have an abacus and this set of abacus formulas, you will be able to greatly save 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: "Why, you two think I am wrong?"
The two little dolls, one skinny and frail, the other a handsome one, were a little scared when facing His Majesty the Emperor. They looked at each other with the same lively eyes, and finally the little dolls, who were beautiful and delicate, bravely bowed and saluted like an adult.
, Nana said: "To reply to Your Majesty... In fact, when the teacher teaches us arithmetic, the exercises are all taken from the Taishi Bureau, and the movements of the sun, moon and five stars are calculated according to the zodiac..."
His Majesty Li Er was astonished 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."
It’s 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 created, 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 else 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 yet emerged. Even Confucian students were not ignorant of the classics and ignorant of worldly affairs. The pragmatic atmosphere was more intense. Therefore, few people opened their mouths or kept silent. Although they talk nonsense about "wonderful techniques and ingenuity", some inventions and creations that can improve the national economy and people's livelihood are generally 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 Wen Yan about the two dolls. In fact, he was indeed pleased 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, magistrate of Bochang County."
His Majesty Li Er couldn't remember who Luo Luyuan was, but the Luo family in Wuzhou had never heard of him, so he was obviously not a member of a well-known family. Di Xiaoxu had just been appointed as Shangshu Zuocheng not long ago, so His Majesty Li Er naturally knew.
I couldn't help but sigh: "They all come from poor families and are smart and handsome. It's rare to find them."
What he likes most is to see the children from poor families have a promising future. Because he was born in a poor family, he knows how to work hard and make progress. After becoming an official, he becomes more conscientious in his work. He is not like the playboys of the rich and powerful 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 Taiji 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 heartily and waved his hand for the two of them to retreat.
The room fell into silence.
Fang Xuanling looked at her nose and heart, holding a teacup in her hand, looking calm and silent.
His Majesty Li Er was a little unsure of how to speak...
He is a heroic man of a lifetime, with a tough mind, a wise spirit, and a mighty spirit. In his eyes, only the eternity of the Tang Dynasty can be sacrificed. 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 in a mountain of corpses and blood?
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? Make someone feel guilty?"
Fang Xuanling was reported to be ill at home. Even though he looked very good now and showed no trace of illness, His Majesty Li Er still spoke with gentle words and sincere feelings.
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 opinion, 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, there was some silence again...
After enduring it, His Majesty Li Er finally couldn't hold it back and said displeasedly: "You are so old, do you still have to lose your temper with someone? After all, this still doesn't punish Fang Jun. You don't have to do this.
."
Instead of calling her "Aiqing", I called her "you" directly. It seemed a bit rude, but in fact, the atmosphere relaxed instantly.
After all, the fighting friendship for so many years has been there, and Fang Xuanling has always been a selfless person. His Majesty Li Er did not 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 at home, 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 your 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?
