I am the son of Cao thief, start the awakening of the tyrant system

Cao Cao, Guo Jia, and Dian Wei came to the grain and grass place, and what they saw surprised them.

According to the guess of the two of them, Cao Mao, who is not proficient in grain and grass dispatching, will definitely be in a hurry after taking over the post of warehouse officer.

The granary will definitely be crowded with soldiers asking for food and grass, and there may be problems with Cao Jun's logistics supplies.

However, at the moment, everything in the granary is in order, and there is no sign of chaos at all.

Cao Cao and Guo Jia looked at each other suspiciously.

This is different from what they both imagined.

"Dianwei, go and call Cao Mao."

Cao Cao ordered.

"Yes, Prime Minister!"

Dian Wei strode towards the granary, and brought Cao Mao back after a while.

"Father, military advisor!"

Cao Mao cupped his hands.

Cao Cao coughed lightly and asked,

"Mao'er, you have been in charge of dispatching grain and grass these days, have you encountered any problems?"

"Reporting to my father, everything went well and there was no problem."

Cao Mao replied.

Both Cao Cao and Guo Jia looked suspicious.

The dispatch of food and grass in the army is extremely complicated.

Even Wang Hou, who used to be the warehouse officer, would make troubles from time to time.

Not to mention Cao Mao who has never had experience in this area.

"If father doesn't believe it, he can check it out."

Cao Mao said softly.

"You can't be careless about food and grass. Maoer, you need to check it out as a father."

Cao Cao said seriously.

Cao Mao beckoned to a soldier,
"Just report the current situation of the granary to the prime minister."

"As ordered, General!"

The soldier took out a booklet,
"Report to the Prime Minister, the food stored in the granary is sufficient, enough for the army to use for more than half a year..."

He made a detailed report to Cao Cao on the number and types of granaries.

Cao Cao nodded slightly, his expression relaxed.

Guo Jia on the side frowned and said softly,

"How long have you been working here at the granary?"

"Reporting to the Prime Minister and the military adviser, I originally belonged to Qingzhou soldiers. This is my third day in the granary."

His answer surprised Cao Cao, Guo Jia, and Dian Wei.

From the soldier's previous answer, Cao Cao, Guo Jia and others thought that he had worked in the granary for a long time before he could tell the actual situation of the granary so clearly.

"Don't lie to me!"

Cao Cao stared at him.

"Yes, cheating the prime minister is a capital offense!"

Dian Wei threatened.

The soldier was startled, and quickly knelt on the ground,

"Subordinates dare not deceive the Prime Minister!"

"It's only been three days, how is it possible for you to be so proficient in the situation of the granary?"

Cao Cao couldn't believe it.

The soldier raised his head and secretly glanced at Cao Mao beside him.

Cao Cao looked at Cao Mao suspiciously.

"Reporting to father, it's because I used a new accounting method."

Cao Mao laughed.

"tell me the story."

Cao Cao, Guo Jia, and Dian Wei were full of curiosity.

"In the past bookkeeping method, all income and expenses were recorded together.

This is not only easy to confuse, but also inconvenient to check accounts. "

While explaining, Cao Mao took the brochure from the soldier and showed it to Cao Cao and others.

"And the accounting method I invented separates the income and expenditure, and all the numbers are clear at a glance."

The three of them looked at the booklet.

Sure enough, as Cao Mao said, each page of the brochure is divided into two parts: left and right.

"On the ninth day of the lunar new year, one hundred thousand shi of grain was sent, including some corn and some fodder..."

This is the revenue recorded on the left.

"General Cao Ren sent someone to collect [-] shi of grain on the tenth day of the lunar new year, including some corn and fodder..."

"How much food General Cao Hong received on the same day..."

This is the expense recorded on the right.

The entire account book is clean and concise, and the use of grain and grass in Cao Jun's camp is clear at a glance.

"In this way, you only need to subtract the income and expenditure and compare it with the final remaining amount of food and grass to know if there is any mistake."

Cao Mao laughed.

Guo Jia carefully looked at the records in the account book, pointed to the Arabic numerals on it, and said suspiciously,
"Sir, what is this?"

Cao Mao took a look and explained,
"This is a number used to indicate quantity."

"What's the use of this?" Cao Cao asked suspiciously.

"Most of my soldiers are illiterate. In order to facilitate them to record the income and expenditure of grain and grass,

I use this concise number to make it easier for them to remember. "

While explaining, Cao Mao took out a wooden stick and drew a line on the ground,
"This represents one."

"This represents two."

"This one stands for three."

He wrote all the numbers from 0 to 9, as well as the symbols of addition and subtraction, for Cao Cao and the others to read.

Cao Cao and Guo Jia are both smart people.

After Cao Mao's presentation, the two instantly understood the magic of these numbers.

The accounting calculations that I was responsible for in the past became easier in an instant after adopting Arabic numerals.

This is simply simplification, turning decay into magic!

No wonder Cao Mao has no literati under his command, yet he can manage the granary in an orderly manner.

It turned out to be because of the numbers!
"Mao'er, did Wenhe come up with all these?"

Cao Cao asked, his eyes fell on Jia Xu behind Cao Mao.

He felt that these things must have been researched by the resourceful Jia Xu.

If this is the case, he will definitely ask for such a smart person from Cao Mao.

Before Cao Mao could speak, Jia Xu smiled wryly,
"Returning to the Prime Minister, you really think highly of me. These are all researched and invented by the young master."

The eyes of several people looking at Cao Mao changed suddenly.

Cao Cao didn't quite believe his ears.

How could my own son come up with such a way?
"I didn't expect my son to be so intelligent."

Guo Jia couldn't help sighing, then he looked at Cao Cao,

"Prime Minister, these figures and the new accounting method invented by the young master are wonderful and simple.

My lord, I think it can be extended to the whole army, and even the court. "

"Yes, with numbers and the new bookkeeping method, there will be no need to worry about confusing accounts in the future.

Maoer, you have made a great contribution! "

Cao Cao patted Cao Mao on the shoulder, feeling very relieved!
"Father is overrated."

Cao Mao smiled lightly.

After Cao Cao saw it, he was overjoyed.

No surprise, Maoer became more and more stable.

"Let's go, let's take a look inside the granary."

Cao Cao took the lead and walked into the granary.

The granary is also in order.

Everyone performs their duties, although busy, but not chaotic.

"Mao'er, how did you manage to be so orderly?" Cao Cao couldn't help asking.

"In the past, the procedures for the warehouse officials to distribute grain and grass were too complicated and chaotic.

So after I took over, I re-improved all the procedures. "

Cao Mao pointed to the people in the granary and explained to Cao Cao, Guo Jia, and Dian Wei.

He divided the soldiers in charge of food and grass into three departments.

The personnel of the registration department are responsible for registering and inspecting the soldiers who come to collect the grain outside the granary.

After confirming that they are correct, the documents can be issued to allow them to enter.

The soldiers entered the granary with documents in hand, found the portering department, and handed over the documents to the

The staff of the transportation department handed over the grain and grass to the soldiers according to the number on the document.

The soldiers came to the final inspection department with provisions and documents.

After inspection and verification, there is no problem with the number and documents, and both parties can sign before they can leave.

The whole link flows smoothly, without any stagnation.
