"Your Majesty, this is an abacus mantra, you only need to memorize it backwards, supplemented by an abacus to calculate addition and subtraction. No matter how large the number, the result can be calculated quickly, conveniently and quickly. ”

Sitting in the spacious and bright office, Fang Xuanling introduced the abacus and abacus formulas to His Majesty Li Er, and called two children to demonstrate for His Majesty Li Er on the spot.

"These two dolls are students in the academy, and they learn quickly, Your Majesty might as well test them with an arithmetic question to test the magic of the abacus."

His Majesty Li Er naturally knows the abacus.

This kind of calculation tool that is clearly distinguished by Fang Jun is still popular in the Tang Dynasty, but His Majesty Li Er, whose mind is above state affairs, has not had an in-depth understanding. In his mind, it's just a calculation tool, whether the arithmetic is faster or slower, what's the matter?

It's just that this abacus formula is a little interesting, so I randomly wrote an inscription on the paper: "Ten thousand three thousand nine hundred and one hundred and twenty plus two thousand and one thousand and one thousand and then subtract and subtract the ...... of one and one " put down the pen, glanced at the two dolls who were obviously a little nervous, and felt that the baby was too small, and this question was a little difficult, so he said kindly: "Count slowly, a stick of incense ......"

Before the words fell, I saw two dolls with an abacus each, crackling and plucking the abacus beads, but said in unison: "Back to Your Majesty, it is equivalent to two thousand thousand Qi and one Bai Jiu to pick up the land." ”

His Majesty Li Er almost bit his tongue, and his eyes widened......

How can it be so fast?

Such a complex number, such a young child, if you can calculate the correct answer with a stick of incense, it is amazing, arithmetic problems are not difficult, the difficulty is that huge numbers require patient calculation and cannot be wrong, but this is just a blink of an eye, what is going on?

Such a child doesn't have the audacity to fool me, right......

His Majesty Li Er looked surprised, and he didn't have to be ashamed to calculate it himself, and turned around and asked Fang Xuanling: "Aiqing, is it correct or not?" ”

Fang Xuanling himself also took an abacus and calculated it, and said with a smile: "Correct." ”

His Majesty Li Er slapped his thigh excitedly and praised: "Good thing! If you have an abacus and this set of abacus formulas, you must be able to greatly save time and improve the accuracy of the annual review and calculation of the household department in the future, which is rare, rare, rare......"

That's a good thing indeed.

But as he spoke, he saw two little dolls and couldn't help but pout......

His Majesty Li Er asked curiously, "What, you two think I'm not right?" ”

The two little dolls, one emaciated and weak, the other carved in pink, were a little scared in the face of His Majesty the Emperor. The same smart eyes glanced at each other, and finally the little doll carved in pink and jade was bold, bowing like an adult, and said, "Back to Your Majesty's words...... In fact, when the teacher taught us arithmetic, the exercises were all taken from the Taishi Bureau, and the movement of the sun, moon and five stars was calculated according to the ecliptic......"

His Majesty Li Er was surprised, and couldn't help but blush.

People usually calculate the astronomical calendar, but they give a lame addition and subtraction problem......

Looking up to the sky to hide his embarrassment, His Majesty Li Er sincerely admired Fang Xuanling: "Aiqing is really a scholar of heaven and man, and he can develop such a set of abacus formulas, and he can teach such an excellent student, I really admire." ”

Fang Xuanling said with a smile: "Your Majesty praises falsely, the abacus formula was made up by my family's unsuccessful Erlang, in fact, it was there when the abacus came out, but it has never been promoted." As for these two dolls, they are not Lao Chen's disciples, and the one who taught them arithmetic was Taishi Cheng Li Chunfeng. ”

His Majesty Li Er was stunned and said with a wry smile: "Your mallet is really ...... Talented! ”

What else can be said?

For Fang Jun's unique ability in invention and creation, even if he is the supreme in the world, he has to write a big "service" word!

At this time, Cheng Zhu Lixue had not yet been born, and everything was inferior, only the social form of high reading had not yet risen, and even Confucian students were not poor and did not care about the world, and the pragmatic atmosphere was more intense. Therefore, very few people open their mouths and close their mouths to talk nonsense such as "strange tricks and tricks", and 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 was a little embarrassed in his heart.

A few days ago, he was bent on degrading Fang Jun out of Beijing, but now he has to praise two sentences......

"Both of you are from the Fang family's servants?"

His Majesty Li Er avoided embarrassment and asked about these two dolls by Wen Yan, in fact, he was indeed pleased with the intelligence of these two dolls.

The two dolls hurriedly replied: "Student Di Renjie, a person from the state, and the ancestor of the family, Shangshu Zuo Cheng Di Xiaoxu." ”

"The student is from Wuzhou, and his father is Luo Luyuan from Bochang County."

I can't remember which one Luo Luyuan is His Majesty Li Er, but the Luo family in Wuzhou has never heard of it, and it is obviously not a family gate. Di Xiaoxu only took office as Shangshu Zuocheng not long ago, and His Majesty Li Er naturally knew about it.

couldn't help but sigh: "They are all from a poor family, smart and handsome, which is rare." ”

He likes to see the children of the poor family the most, because he is from a poor background, he knows how to work hard, and he is more conscientious after becoming an official, not like the children of the family who are so sloppy and playful, only knowing their own selfish interests and ignoring the righteousness of the empire.

With joy in his heart, His Majesty Li Er tore off a pair of dragon jade pendants from his waist and said with relief: "I reward each of you with a piece of carry-on, which is not only to reward you two for your intelligence, but also to encourage you two not to be complacent, to continue to work hard, to be able to get the careful teaching and cultivation of Fang Xiang, there are few people in this world who have such blessings." When the two of you grow up to participate in the imperial examination, I will be on the Taiji Palace, hand-picked by Zhu Bi, watching you wait for the hairpin to wear flowers, and cross the horse to parade the streets! ”

The two dolls were so excited that their faces turned red, and they carefully accepted the emperor's reward, and said in unison: "Di Renjie (King Luo Bin) will live up to Your Majesty's expectations!" ”

His Majesty Li Er laughed and waved his hand to make the two of them retreat.

There was silence in the room.

Fang Xuanling looked at his nose and nose, holding a teacup in his hand, and his expression was calm and silent.

His Majesty Li Er didn't know how to speak......

He is a hero, tenacious and wise, and only the Tang Dynasty has thousands of years in his eyes, and no matter who stands in front of this premise, he can be sacrificed.

But he is also a righteous person, in the face of the old guy who followed him in the mountains of corpses and the sea of blood and death, how can he have no affection?

Before, he felt that the crown prince was not suitable for the position of prince, so he wanted to get rid of Fang Jun, the most powerful humerus next to the prince, which was a major event of the country, even if Fang Jun was meritorious, even if Fang Jun was Fang Xuanling's son, His Majesty Li Er would not hesitate.

However, now facing Fang Xuanling, how could he not have a trace of apology?

People are not plants and trees, who can be ruthless......

After a pause, His Majesty Li Er asked warmly, "Has Aiqing's body ever been better?" After all, as you get older, proper cultivation is still necessary, don't work around the clock like back then, once you are tired, wouldn't it make someone feel guilty? ”

Fang Xuanling was sick at home, although he seemed to be looking very good now and did not have the slightest sickness, His Majesty Li Er was still gentle and sincere.

Although everyone knows that Fang Xuanling is euphemistically expressing his dissatisfaction with His Majesty Li Er's intention to demote Fang Jun out of Beijing, or his strong opposition to His Majesty Li Er's desire to change the court......

But His Majesty Li Er was not angry at all.

With his friendship with Fang Xuanling and Fang Xuanling's achievements over the years, he is qualified to express his different political views in His Majesty Li Er.

Fang Xuanling said: "Thank you for Your Majesty's concept, it's just that the qi is weak and weak, and I accidentally contracted the wind and cold, and it's not a big deal." ”

His Majesty Li Er nodded and said, "Well, that's good, go back and ask the palace to send some more nourishing things." ”

"Thank you, Your Majesty."

Then, it was a little cold......

After enduring it, His Majesty Li Er couldn't hold back after all, and said unhappily: "You are also so old, is it possible that you still have to have a temper with someone?" Isn't this still not punishing Fang Jun after all, you don't have to be like this. ”

did not call "Aiqing", but directly called "you", which looked a little unpolite, but in fact, the atmosphere eased instantly.

After all, after so many years of fighting friendship, Fang Xuanling has always been a selfless person, and occasionally plays with his temper for the future of his children and grandchildren, His Majesty Li Er doesn't think it's a big deal.

Fang Xuanling said indifferently: "If the old minister refuses to go to the court at home without complaining about his illness, can His Majesty change the election?" You know that what Lao Chen said is not that Fang Jun is not punished. In fact, the Fang clan bathed in the emperor's grace and holy family, and the whole clan was grateful to Dade, even if His Majesty reduced Fang Jun to the people, how could he dare to have the slightest resentment? ”

His Majesty Li Er's face sank.

He knew that Fang Xuanling was referring to the matter of easy storage......

However, this matter is a bone spur in the heart of His Majesty Li Er, how can it be easily changed?
