Buried in the pile of books, until the moon branches, Lu Qi rubbed his temples and leaned into the chair.

"Alas, it's not easy to sort out this mess." Lu Qi rubbed his waist and thumped his legs, walked out of the door and walked around twice.

There are three entrances before and after this general's mansion, the front hall, the main hall, the flower hall, and a back garden with a pool, which can be described as everything, but only Lu Qi and his own soldiers, with more than a dozen brocade guards, moved in.

In addition, Lu Qi didn't have time to add any furniture, the remnants of flowers and willows in the yard were uncared for, and the brick floor was overgrown with weeds, which looked quite desolate.

"It's a bit of an atmosphere like Lanruo Temple." Lu Qi sat down on the steps covered with dead leaves, and the breeze was slightly chilly.

After sitting for a while, Lu Qi was going to make some water to make a cup of strong tea, and he had to continue to fight at night.

As soon as he got up, he saw a little light coming from the front hall, and when he looked at it in the moonlight, it turned out to be Cen Qun, and he was followed by two figures, one tall and one short.

Seeing that Lu Qi was here, Cen Qun hurriedly said: "Lord Lu, Mrs. Zun and the imperial brother are here!" ”

Those two figures turned out to be Chen Yin'er and Wei Cheng, and they hadn't seen Lu Qi for a while, so Chen Yin'er missed it very much, so he led Wei Cheng to find it.

Fortunately, Lu Qi had already arranged a brocade guard at home to escort him all the way.

"Husband."

"Lord Lu."

"You're here!" As soon as Lu Qi saw them, he was in a much better mood.

The three of them entered the house hand in hand, and the lamp was lit on the table, Chen Yin'er looked around with the light, and said with a smile: "Such a big house, it's empty, it's not good-looking." ”

Lu Qi nodded: "Go back and ask someone to make some household goods and plant some flowers and plants." ”

Boiling water to make tea, the three of them sat down around the coffee table, drinking tea under the lamplight, talking and laughing, Lu Qi suddenly had a flash of inspiration in his mind:

"Will the lady settle accounts?"

Chen Yin'er smiled: "What a small look! Although I haven't studied, I've always been in charge of our family's accounts, so why don't you hire a bookkeeper? ”

"I'm short of Mr. Billhouse!"

Lu Qi jumped up, pulled Chen Yin'er to the side of the bookcase, and pointed to the mountain of account books:

"Here are the accounts of the right outpost battalion's salary and money withdrawal and military procurement in recent years, and I have the heart to clean it up, but I can't figure it out. You're just in time, give me a hand! ”

Chen Yin'er picked up one of them and flipped through it: "Haha, it's such a mess!" I can't imagine that the officials in the barracks are not as good as me, a deep girl. ”

Lu Qi sat down: "Or Zhao Yongqi and the two of them are fighting this idea, they are in charge of the finances of the whole battalion, and the fat meat is by the side, where can they not get oil?" ”

Wei Cheng, who was still small, stood on tiptoe, and also took a book and flipped through it: "What is written on this?" ”

"You're too young to know you, these are ledgers." Chen Yin'er smiled and touched his head.

Wei Cheng was not happy now: "Although I have never gone to private school, my brother taught me to read and write before, and I wrote the complaint last time!" ”

"Yo!"

Lu Qi raised her head in surprise, she had also seen the form, although the words in it were plain, the logic of cause and effect was clear, and it didn't look like a ten-year-old child could write it.

"I didn't expect our royal brother to have such a literary talent!" Lu Qi picked up a blank piece of paper with a smile: "It's just that learning to calculate accounts not only requires literary talent, but also arithmetic." Come, try to learn my way. ”

Lu Qi listed Arabic numerals into a table, and taught them the vertical method, so that the two of them could start with simple calculations.

The most difficult thing for people in this era to learn this knowledge is that the original knowledge in their minds has been deeply ingrained, and it takes more time to replace the original knowledge.

And Chen Yin'er and Chen Yin'er have not experienced arithmetic learning, and they are both smart and clever people with excellent memory.

Wei Cheng was praised, Chen Yin'er wanted to show his hand, and he worked hard to learn and practice, and no one would let anyone.

By the time of the third watch, the two cooperated and were able to check simple accounts.

"Just now, I thought that this Arabic numeral was really redundant, but now that I am familiar with it, I realize that this is much more refreshing than the method I used!" Chen Yin'er put down the pen and blew the ink.

Wei Cheng was even more happy, and his learning was no slower than Chen Yin'er: "Brother Wang said that Lord Lu is a genius in the world, and what Lord Lu teaches is much better than following the great Confucian masters!" ”

Looking at the two of them who were hungry for study, Lu Qi couldn't help but feel emotional.

She comes from the era of information explosion, where everyone has the right to education as long as they want to learn. Elementary school arithmetic knowledge like this has long been like grass mustard on the side of the road, which is part of common sense.

However, for the people of this era, knowledge is something more precious than gold, but whenever there is a little opportunity to learn, they will not let it go.

Late at night, Lu Qi yawned: "Okay, okay, if you want to sort out this pile of accounts, it can't be done overnight, so go to sleep." ”

But the two disagreed, Lu Qi didn't rest, and they insisted on not resting.

In Chen Yin'er's words: "If there is one more person to help, we will sort it out earlier, we are not here to play." ”

……

The night is long, the lights are flickering, the light and shadow in the courtyard are shining, and the moonlight is flickering in the west.

Dongfang seemed to reveal some white meaning, the time was already five watches, Lu Qi knocked on his stiff and sore waist, stood up and walked two steps.

The slight sound woke Wei Cheng up, he was busy wiping his saliva and sat up, Lu Qi smiled: "It's still early, you go to bed and sleep for a while." ”

This kid is honest, seeing that Lu Qi and the two didn't sleep last night, he also stayed up and refused to sleep. But when he was young, he couldn't resist sleepiness, and finally fell asleep on the ledger.

"I ...... I'm sorry Lord Lu, I said last night that I would settle accounts with you, but I fell asleep. Wei Cheng lowered his head guiltily.

Chen Yin'er rubbed her eyes sleepily: "What does it matter, you are still a child, you should sleep more." ”

Lu Qi wouldn't blame him.

After stretching his long waist and stretching his muscles, Lu Qi rolled up his sleeves: "What do you want to eat in the morning?" General Ben will cook for you himself! ”

"Oops!"

Suddenly, Wei Cheng screamed, desperately wiping the ledger with his sleeve.

He had always been old, and he had never shown such a panicked expression, so Lu Qi leaned over to take a look.

I saw that there was a large pool of water stains on the ledger, which stained the ink, and Wei Cheng's face was already red at this time, and his eyes were dodging and he didn't dare to look at Lu Qi.

"Hahaha, could this be your drool?" Lu Qi said with a smile.

Chen Yin'er also came over to take a look: "The account books are all wet, it seems that it is not easy to settle the accounts." ”

Wei Cheng covered his face, just looking for a crack in the ground to get into.

"It's okay, it's okay." Lu Qi hurriedly comforted him, picked up the account book again, and looked at it, it turned out to be the one that Cen Qun said, sewn under the carpet.

"Huh?"

Lu Qi was looking at it, and suddenly became serious.

Through a night of account management, Lu Qi has roughly straightened out the monthly expenses in the right sentry camp: every month for the purchase of vegetables and vegetables, there is a special account book registration, and the transaction volume is very large.

"The vegetables purchased are obviously recorded in that account, why are there only a few things recorded here?"

Chen Yin'er yawned: "If it's someone's private account, then it's not strange." ”

"Private accounts?"

Lu Qi shook his head: "Hong Dusi has cooking soldiers in the camp on weekdays, and there are also domestic servants serving him outside, so he can't cook and eat by himself, so why set up a set of private accounts to buy vegetables?" ”

Seeing that he might have made a meritorious service, Wei Cheng became excited: "Yes! I remember it so casually in other account books, but this one remembers the rules and regulations clearly, which means that this must be something important! ”

What is it that is so mysterious that the ledger needs to be coded? It's definitely something you don't want anyone to find out.

Thinking about what the Shenji Camp is for, could it be said that what is remembered here is ......

Lu Qi narrowed his eyes and called Cen Qun: "I have a letter, you hand it over to Commander Mu in person for me!" ”
