Three Kingdoms: From Hulaoguan to Global Hegemony

Chapter 256 Abacus and Abacus

Master Kang has been regarded as the reincarnation of the gods by everyone, and now Liu Yu is the only successor, who doesn't want to be honored as a "disciple of the gods", even if the nephews in the family can only learn superficially, it is enough to shine in the family.

Liu Yu has long known that once he comes up with some inventions that transcend the times, he will surely become the focus of everyone, and even be misunderstood as a "monster" by those in power.

After all, he has changed too much from before. If there is no reasonable explanation, he may be regarded as a "guinea pig" for research.

So he created a god for the world from the very beginning, and whatever he didn't want to do, say, or couldn't explain positively, he could push to his master - Immortal Kang!

"Thank you for your kindness, my lords, but what I, Liu Yu, learned from my former teacher is only superficial, and the inventions you have seen are all relics left by my teacher, and there are not many left now. !"

"...So I actually don't know how to make those things! In addition, the teacher has a strict order, and there are no more than three apprentices before Buhuo! I really feel sorry for the teacher's order!"

After Liu Yu finished speaking, he clasped his fists in return, and politely declined the requests of all the ministers to be his nephew's apprentices one by one.

Forty is not confused, but now Liu Yu is only 20 years old!
As soon as everyone heard that Liu Yu could only accept three apprentices at most, many junior officials withdrew in disappointment, because they did not dare to continue to compete with the senior officials of the Sangong and Jiuqing.

At this time, Ma Teng and Yang Biao, who were standing by the side, stayed out of the matter. They were not familiar with each other at first, but now they chatted together with smiles because they heard Liu Yu say, "It's only three years in a lifetime."

Ma Chao, the son of Ma Teng, is Liu Yu's serious first disciple. Yang Xiu, the son of Yang Biao, also formally worshiped Liu Yu as his teacher.

Back then, Yang Biao advised his son to learn how to farm from Liu Yu, but now it seems that his decision at that time was definitely a wise move.

There was still the last place to accept apprentices, Wang Yun and Shi Sun Rui were fighting hard, but Liu Yu walked up to Sima Fang.

Liu Yu said with a smile: "Brother Jiangong, don't worry, the matter of accepting your second son will not change!"

Sima Fang vaguely remembered that when Liu Yu was drinking at Liu Yu's house that day, Liu Yu mentioned this matter, and his second son was Sima Yi.

Thinking that his second son could worship under the disciple of the Immortal, Sima Fang happily thanked him for his son.

"Thank you, Zhongshan Wang Chengquan, sir! When the time is right, I will call Quanzi to come to the capital to learn from him!"

The last easter egg fell on the head of Luoyang Commander Sima Fang's son, and everyone could only sigh with envy.

It's just that this matter made Li Ru even more suspicious that there was some ulterior secret between Sima Fang and Liu Yu.

He thought sinisterly, from the matter of transshipment of grain and grass, it seemed that Liu Yu's criminal evidence could not be collected, and if it was impossible, he could only find a way from Sima Fang.

Shi Sunrui was a little frustrated, his own people were not arranged to enter Taicang, and the matter of apprenticeship to his son was also declined, but the shrewd one rolled his eyes and thought of another good idea to get in touch with Liu Yu.

But this time he would not blindly say it in front of everyone, and he felt that he had to bring a generous gift to Liu's mansion to bring up this good idea in order to show his sincerity.

……

In the end, the lowercase numbers were approved by the ministers, so the battle for posts in Taicang came to an end, and the ministers left in dismay.

Cui Di and Zhou Fang were officially appointed as supervisors and pianshi in Taicangli.

This can also be considered as Liu Yu fulfilled his previous promise to the two and found a "formal job" for them.

Although Cui Di and Zhou Fang are both wealthy households in Luoyang City, they have always been attached to other wealthy clans, and there have never been any big names in their families.

Now that the two have become officials in Taicang and received the salary of the imperial court, it can be regarded as a little glory for the ancestors!
And the two of them became more determined to always be loyal to Liu Yu.

……

After arranging positions for Cui Di and Zhou Fang, Liu Yu called the operator named Xu Yue just now.

Liu Yu asked: "I saw that you were holding a ... abacus in your hand when you calculated the number just now. I wonder who taught you the method of abacus calculation? Can you invite that person to come and explain it?"

The abacus has long been invented by the ancients and used in calculations, but it is not called abacus calculations but calculations.

Liu Yu has long discovered that the thing in Xu Yue's hands is very different from the abacus on the market. It is more like the abacus of later generations, but it is a little crude and has fewer digits.

The originator of the abacus was created by Liu Hong, a mathematician at the end of Han Dynasty. Does this person named Xu Yue have anything to do with Liu Hong, a great mathematician?

Hearing Liu Yu's question, Xu Yue didn't dare to hide anything, and respectfully stepped forward and replied, "This abacus was made by one of the villain's masters, and the calculation method of Yiying was also taught by his old man!"

"However, my teacher Liu Hong... is old, and he went to Taishan's hometown to take care of him the year before last!

Hearing this, Liu Yu was basically sure that the master Liu Hong Xu Yue mentioned was undoubtedly the master of mathematics Liu Hong who first invented the prototype of the abacus.

"I happen to have a kind of ... abacus invented by my master here. I wonder if you dare to try abacus calculation with me? Let's see if my master's abacus is better, or your master's abacus is stronger?"

After Liu Yu finished speaking, he took out an exquisite little abacus from his sleeve.

This abacus was definitely not invented by Master Kong, but Liu Yu bought it from the system supermarket for 300 Wuxing coins.

Xu Yue was shocked when he saw how delicate the abacus was, and looked at how crude the abacus in his hand was, it was simply incomparable.

In order to be fair, Liu Yu asked Cui Di to write down a few sets of numbers with large values ​​on the paper, and then he and Xu Yue competed to see who could calculate the sum of these sets of numbers first.

The abacus in Xu Yue's hand can only be regarded as a prototype. Although there are upper and lower gears, the number of digits is limited, and it is impossible to calculate when encountering relatively large numbers. Moreover, the abacus was really used proficiently after the Song Dynasty.

So Xu Yue used it very slowly at this time, and he didn't master too many skills at a glance. In addition, he only added two or three sets of numbers before stopping in embarrassment.

"This number is too big, I need two counting boards to continue counting!"

After hearing this, Liu Yu admired Xu Yue's ability to respond. He really is a person who is proficient in arithmetic and knows how to infer other things from one instance.

"Your abacus is still too limited. You must know that there are a lot of materials that go in and out of Taicang every day, but my abacus has enough digits, and there is a more convenient formula for calculation!"

At this time, Liu Yu had just started his calculations, only listening to him chanting formulas such as "three up three, five down, five into one...", and then he calculated the set of data without using half a cup of tea. .

Xu Yue, Cui Di, and Zhou Fang were all shocked by Liu Yu's operation. This abacus is amazing. It can calculate such a large number so quickly!
