Yu Xing didn't leave for long, but Xie Yuan came over in a panic, obviously a little surprised that there was suddenly an extra subordinate.

"Brother Fang, that man was sent by you to help me?" Xie Yuan opened his mouth to ask.

"I'm worried that you can't be busy, so I've arranged for you to work in a bookkeeper to manage the ledger or something. This way you can make it easier and just check the books on time. In addition, you can call him later, and I will teach you a way to calculate and keep accounts, so that you can avoid blurring your income and expenditure. Fang Yun nodded in acknowledgement, and then opened his mouth to admonish.

"This little sister naturally knows...... It's just that the guy actually peed his pants, is it really okay for such a person? Xie Yuan was very curious about what Fang Yun would give her, but she was still very skeptical of Yu Xing's character.

"Haha, he's just frightened, and I forgot to let him change his clothes before going to you, so he's embarrassed now, right?" When Fang Yun heard this, thinking about the appearance of Yu Xing peeing his pants, he couldn't help but laugh.

"Ah, no wonder when I say how I came here, I ask about the smell of pee!" Xie Yuan can be regarded as Fang Yun's childhood sweetheart, so that it is indeed a bit unsuccessful to speak in private.

However, as soon as she said that, Fang Yun suddenly realized, no wonder she felt that something was wrong recently, and she dared to be affectionate because Yu Xing urinated in his tent. Looking at the blood stains splashed everywhere, I couldn't help but have a headache, and secretly said that in the future, I would have to change the tent of the meeting, which would be specially used to deal with this kind of thing, otherwise I wouldn't have to sleep in the future.

This is also something that can't be helped, as a traverser, he has a lot of things that need to be slowly used to and adapted.

After all, Fang Yun was already a school captain, and if he discussed something with his subordinates, he would have to go to the camp where he was resting, which was indeed unreasonable.

"I'll ask for another tent with the quartermaster, but it's hard to say if I can get it." Xie Yuan is the head of the civil officials under Fang Yun, and this kind of thing is naturally done by her.

"Let's go check it out first! By the way, the time is almost up, don't be busy with anything first, let's eat first! Suddenly it was dinner time, and Fang Yun naturally didn't want Xie Yuan, a little girl, to be too busy.

After all, she is only 13 years old this year, how can she be so tired?

"Brother Fang doesn't need to worry, in fact, we really don't have anything to do here. After all, military supplies and grass are almost under the overall management and distribution, and military exploits are also uniformly registered, and even military law is taught to Qu Shuai's personal soldiers in turn, so there is really not much we can do. Xie Yuan smiled and said.

"Just remember not to tire yourself, if there is any heavy work, just leave it to that guy Yu Xing." Fang Yun was still very worried.

"This girl knows......" I could hear that Fang Yun cared about herself very much, and Xie Yuan also replied shyly, but her heart was warm.

After a while, the family camp really brought dinner, and looking at the family members who came to the camp with a big pot of corn, Xie Yuan felt as if he was in a different world. A few days ago, I was still like them, washing clothes for the soldiers, fetching water and cooking, and even helping to take care of the wounded soldiers, taking turns to be on duty at night...... After only a few days, I was already sitting here, enjoying their services.

"Aunt Chen, how are the sisters of the Liu family?" Probably seeing an acquaintance, Xie Yuan ran over.

"Oh, it's a girl? The lady of the Liu family, she went to ......" Aunt Chen looked up at Xie Yuan, and then said indifferently, it seems that she has long been used to this situation.

"How?" Xie Yuan never thought that the person who used to live together and take care of her like a sister would actually leave.

"Throw herself into the lake, a man dies on the battlefield, and there is no one else at home, how can you stand calling her a weak woman?" After Aunt Chen finished speaking, she sighed helplessly and continued to get busy.

In fact, compared to the woman surnamed Liu, Aunt Chen is the strongest, her only son has died in battle, but she still insists on staying in the camp to help work, just to watch the day when the Yellow Turban Army overthrows the Han Dynasty. Because, that is his son's will, he can't see it, and the mother has to see the end for him......

"Zhumen's wine and meat stink, and there are frozen bones on the road...... Troubled times, this is the phenomenon of troubled times...... In a troubled world where human life is as cheap as earth! Fang Yun, who heard this on the side, also gritted his teeth, and finally could only sigh.

"Brother Fang, when will the troubled times end?" Xie Yuan asked with a bit of crying.

"Troubled times, but it's just getting started......" Fang Yun looked at the sky in the distance and said something that only he knew.

The Yellow Turban Rebellion was just the beginning of the rebellion at the end of the Han Dynasty, and the greater turmoil was still to come. There are more than 50 million people, and when the Three Kingdoms returned to Jin, the number on the bright side was only 7.7 million, which is sad and lamentable......

There are some internal reasons for why Wuhu can mess with China, but more often than not, it is the scarcity of the population, so that the shortage of soldiers. With hundreds of thousands of people guarding the huge northern frontier, facing an army of hundreds of thousands of Hu people, it was naturally easy to be defeated by the other party.

Thinking of this, Fang Yun couldn't help but ask himself, when he traveled to this era, had he been reduced to the point where he had no ambition at all? When I was young, I looked at history and shouted "Although I am far away, I will be punished", has the enthusiasm has cooled?

However, there is no point in thinking about this at this stage, after all, if the Yellow Turban Army finally fails, it will be difficult for him to gain a foothold in this world, let alone support the society and revitalize China. In the end, he said that he couldn't end up like Zhang Yan, accept Zhao'an as a young general, and finally be excluded from the political margins, and live in peace and quiet?

"Eating, I cherish the present more than those in the long run!" Fang Yun sighed and motioned for Xie Yuan to go to dinner.

It's just that this meal, eating really doesn't have any taste, that is, hastily filling the stomach, after all, hunger is a real feeling.

After dinner, Fang Yun took Yu Xing and Xie Yuan to his tent. He's a lieutenant, so he's got some lamp oil, but he doesn't have to worry about lighting at night. It's just that he can't get this paper, and this thing is still very rare, and ordinary people really can't afford to use it.

I had no choice but to teach them on the ground, and then find another way.

"First of all, what I'm going to teach is to come up with a counting symbol that I came up with in a hurry, which I call Fang's number!" As for what kind of Fang number was turned into Arabic numerals, Fang Yun didn't mean to be ashamed at all.

After all, it will be at least a few hundred years before this kind of counting is commonly used in the country of origin, so it is absolutely original to take it out at this time!

As Fang Yun wrote out the Arabic numerals from zero to nine, and patiently taught them how to identify these numbers and how to use them simply.

Not to mention that Xie Yuan's eyes were sparkling, and he listened to Fang Yun's teachings with great admiration. It was only said that Yu Xing still had a hint of vague disdain at first, but then he looked at the numbers on the ground in surprise, unable to extricate himself, but he was deeply shocked.

"This is the use of these numbers, now I teach the addition and subtraction of these numbers, because the time is limited, so I will speed up the speed of teaching, and ask me later if I don't understand!" Fang Yun looked at the time, and then said solemnly.

"Yes!" The two of them have no opinion on this, after all, it is already an incomparably precious thing to have the opportunity to learn, and if you are picky, you really can't say it.

With Fang Yun's professor, the two of them immediately mastered the use of these numbers, as well as simple addition and subtraction.

"Lord......" Yu Xing shouted in a low voice.

"If you have something to say, you can say it!" Fang Yun looked up and returned, actually hearing the word 'lord', he was still a little happy in his heart.

"This kind of Fang's number is indeed very convenient to calculate, but it is also easier to tamper with, so I'm afraid it is not very suitable for use in account books!" Yu Xing knew that this was the first step to gain his trust, so he naturally admonished him very seriously.

"Because of this, when it comes to bookkeeping, it is important to use Fang's numbers together with commonly used numbers. Of course, now I still have a way of bookkeeping, called 'loan bookkeeping', time is limited, you listen to the maximum extent, what do you don't understand, you will ask after I finish teaching! Fang Yun was still very satisfied with Yu Xing's discovery, smiled and took out the second good thing by the way.

Credit accounting is a more commonly used double-entry accounting method in later generations, and it is rare to see it at a glance, clear and transparent. It is true that Fang Yun also knows nothing about this thing, so he can only tell the general principle, how to improve it, naturally teach these two guys who are good at bookkeeping to deal with it.

Sure enough, after Fang Yun introduced this bookkeeping method, although the two of them were eye-catching, they obviously felt that this bookkeeping method didn't seem to be perfect, or that some places were a little vague.

I wanted to reflect this problem, but I didn't want Fang Yun to directly give this problem to them to think about, looking at this irresponsible teacher, Xie Yuan directly puffed up her cheeks and sold cuteness, while Yu Xing couldn't cry or laugh.

finally coped with the past, and let the two of them go back to think about it, but they began to practice "Five Birds Shaping the Body" again. An hour later, Fang Yun dragged his tired body back to the tent, which had been cleaned up by the soldiers at the moment, so there was no smell at all.

But even if he had, he couldn't scruple so much, so he collapsed directly on the bed and fell asleep.
