After confirming that no one will come in at this time,

He took out the Notebook of Heaven's Destiny and began to complete today's diary.

[Boss Cao is going to Suanzao soon,

Although facing the battlefield directly will be dangerous,

But I am no longer the same person.

I can't kill people,

But want to kill me,

Then it depends on whether you can catch up with me...]

After writing bits and pieces of what I saw and felt today,

Lu Yan again thought of things like grain and grass statistics that he had been dealing with recently.

"The bamboo slips are really troublesome to use, and the forms are not easy to draw..."

After a pause,

After hesitating and weighing for a while,

Lu Yan decided to give it a try,

[The statistical method of keeping this running account nowadays is really uncomfortable.

Not only is it difficult to reconcile accounts,

Moreover, inspection is quite time-consuming and labor-intensive.】

[Let’s make a form first!]

Lu Yan drew a simple form on his notebook,

For your own convenience,

He wrote the Chinese capital numbers corresponding to the Arabic numerals at the top of the form.

In the table, Arabic numerals are used to record various data, as well as the final summary.

In this process,

He inevitably made some sketches of calculations in the blank space next to him...

[Well, it’s done, this way still looks the most comfortable. 】

...

In the meeting hall,

Cao Cao guessed that it was time for the "immortal" to get off work again.

In view of the fact that this military aircraft meeting was basically just talking to oneself,

So Cao Cao simply said to everyone:

"Everyone, we will leave immediately for the Jujube Alliance tomorrow. We will stop here today."

"Here!"

"Here!"

"Here!"

Without waiting for others to get up,

Cao Cao hurriedly left the meeting hall alone.

He can't wait to read today's diary now.

Go back to the house and open the diary,

Today’s diary was updated on time.

But the content of today’s diary,

Except for the first few sentences that I can understand,

Those square grids and crooked lines at the back immediately confused Cao Cao.

"What are all these things?"

Cao Cao rubbed his eyes,

Then start reading from the beginning again.

After he watched it several times,

He finally understood the meaning of these Arabic numerals,

"This should be the corresponding meaning of the symbols written on it.

1 corresponds to 1,

2 corresponds to two...

That’s it, that’s it!

Can it be combined like this?

The person who created this statistical method is simply a genius... Oh no, if it was created by an immortal, then there is nothing to be surprised about..."

Cao Cao was a versatile man in both civil and military affairs.

He made some changes according to the instructions, and after finally confirming it a few times, he could clearly understand the meaning of the form.

After realizing the huge benefits of this statistical method,

Cao Cao immediately couldn't help but want to promote it.

But after thinking about it again and again,

Cao Cao still felt that he should shelve this idea for the time being:

"Although the method is good,

But plagiarizing the immortal's things rashly will probably anger him, and it will also expose the secret that I can see his diary.

If the immortal leaves in anger, I will lose more than I gain.

If he takes my life again when he is so angry...tsk tsk...then he is really committing suicide...

You still have to hold on,

Anyway, I have learned this method,
Chapter completed!
