Liu Hong couldn't believe it, you are a young person, how can you know this thing? Besides, I just made this one, how can Fei Qian know? Is there really such a thing as a naturally intelligent person?

Fei Qian looked at the "abacus", and finally understood why there was always an awkward sense of familiarity, familiarity was because he had learned this method of operation when he was in elementary school, and the awkward thing was that this abacus was put into the middle layer of the grid with beads one by one, instead of a wooden stick strung between the beads to move up and down.

"Why don't you string them together with sticks?" Fei Qian thought so, so he said it casually.

"What sticks?" Liu Hong on the side was puzzled and asked Fei Qiandao. Could it be that there is any inadequacy in my calculation that I have worked so hard to come up with?

"This ......" Fei Qian hesitated a little, should I order some strange technology tree to come out?

When was the ancient Chinese abacus finalized? Tang Dynasty or earlier? Anyway, the Song Dynasty is definitely there, remember that there is a shop on the counter in the Qingming Shanghe map, and the form is basically no different from modern times.

Now that this calculation is counted, it shouldn't have any effect, right? Fei Qian thought to himself, but he had said all the words, and it was not easy to take them back, so he simply asked for a piece of paper and drew the abacus of the future generations.

Liu Hongkankan waited for Fei Qian to finish painting, grabbed it in his hand before Cai Yong, nodded his head, and praised it in his mouth, "Yes, why didn't I think of it...... In this way, there is no fear of loss, and the pearl of the same pillar, the heaven and earth increase to people, tsk...... Wonderful! Wonderful! ”

"Heaven and earth increase in people" actually means that the top row of beads is called the dzi, and the beads at the bottom are called the earth beads.

However, Liu Hong also found something he didn't understand, and pointed to the abacus drawn by Fei Qian and said: "Why do you want to increase the heavenly beads to two and the earth beads to five?" -- If the modern abacus uses the decimal system, in fact, the top and bottom ones are not used, but Fei Qian didn't think much about it and directly drew it in the form of the modern abacus.

Fei Qian didn't know why the modern abacus should add these two beads that were not used, so he said: "The lower bead is five into one, and the upper bead is two, so it is easy to calculate." ”

"The lower bead is five into one, and the upper pearl is two into one......" Liu Hong nodded after hearing this, and shook his head again, Fei Qian didn't know whether Liu Hong agreed with his statement or not.

In fact, Fei Qian is not a professional after all, and he does not know the development history of the abacus, so he naturally does not know the evolution of the abacus.

In the course of the development of the abacus, gradually from a small number of people who study mathematics to a large number of people who need to deal with numbers, and a large part of them are merchants, and in ancient times, there are not only decimal calculation models, but also hexadecimal, such as the ancient pound for sixteen taels and so on, so the business in order to calculate the hexadecimal convenience, then add the heaven and earth beads on the ancient abacus, so that the sum of the heaven and earth beads is equal to fifteen, which happens to be used both as far as the decimal system and as for the hexadecimal system.

Liu Hong stared at Fei Qian with blazing eyes, if he wanted to accept Fei Qian as an apprentice and just talk casually, now he really has this thought. This son is good at arithmetic, and in a moment, he improved the abacus that I took so long to figure out, alas, how could he be robbed by Old Man Cai?

Cai Yong also saw something on the side, pondered for a while, and simply said: "Ziyuan is newly accepted for me, although it has been introduced, but it is not an auspicious day, it coincides with the autumn class of Taixue tomorrow, so simply salute together, if Yuan Zhuo has time, can he pay a courtesy?" ”

In the Han Dynasty, Taixue generally recruited a group of new students in spring and autumn, the so-called spring and autumn classes. Previously, Taixue was closed for a period of time due to the disaster of the party, and then Emperor Ling of the Han Dynasty rehabilitated the party, so he naturally reopened Taixue.

Liu Hong looked at Cai Yong, nodded, sighed, and then said, "Naturally, I want to come." "-This is completely hopeless, this kid is Cai Yong's person, and he can't grab it, but, hehe-

Cai Yong saw that Liu Hong agreed, so he didn't say anything more, so he told Fei Qian that he could go to prepare and prepare, and let Fei Qian go back first tomorrow.

Fei Qian waited until he got out of Cai's Mansion, and he still felt a little unconvinced, it had only been a few days of hard work, and it seemed that he had upgraded himself?

Cai Yong said to go back and prepare for preparation, what to prepare? Naturally, it is the gift of apprenticeship, which means that as long as Fei Qian has an apprenticeship in Taixue tomorrow, he will get rid of the word "name" and become Cai Yong's real disciple.

This is really a sudden ...... that happiness does not come

However, Fei Qian suddenly thought of a question, and couldn't help but have a big head, originally he was going to leave Luoyang in a few days for the reason of going to Jingxiang to study, but now he has been accepted as a disciple by Cai Yong, and this reason has become a joke, so how can I leave Luoyang?

If you can't leave, how can you save your life in this turmoil?

It's really a plan that never catches up with change, how can that be?

******************

In fact, Fei Qian is far from the only person who has troubles now.

Yuan Kui is one of them, and he is also very troubled after Yuan Shao resigned and ran away.

Yuan Shao's departure is no less than exposing the dispute between the Yuan family and the concubines to the world. In fact, this matter is inevitable in every family, but most of them are silently digested in the family, and few people like Yuan Shao know about it all over the world.

And the most important point is that it is also being used.

Dong Zhuo Pifu actually sealed the Bohai Taishou for that rebel! This shows that the two sons of the Yuan family want to fight, but it's a pity that he Yuan Kui can't say a word.

Now Dong Zhuo, in the name of the imperial court, said that although Yuan Shao had a small fault, he could still use it, so he worshiped Bohai Taishou to protect the good people, eliminate bandits, and make up for the merits......

All aspects are blocked, what else can Yuan Kui say? Don't let Yuan Shao serve as the Taishou? The reason? Is the Yuan family's children incapable? Do you want to serve the imperial court? Or don't you make up for it? Or do you want to immediately give a pursuit order to chase and kill?

Although Yuan Kui really wanted Dong Zhuo to really engage in a thousand-mile chase, but the laws of the Han Dynasty stipulated that it was reasonable and legal for relatives to hide each other, could Yuan Kui still be able to carry out a righteous killing of relatives behind the laws of the Han Dynasty?

This righteous annihilation of relatives is really not a good word in the Han Dynasty, do you want the reputation of the Yuan family? So Yuan Kui had no choice but to pinch his nose and admit it.

However, just like this, Dong Zhuo and Li Ru were asked to mix sand into Yuan's house like this, and Yuan Kui was unwilling to think about it, so he ordered his subordinates to summon Yuan Shu.

Since it is no longer possible to hide it, just put it on the table in a dignified manner! Let everyone in the world see the spirit of the Yuan family, the fourth and third princes!
