Under Qin Yu's teachings.

With the cooperation of Xiao Nan, Shen Binglan and two minor officials.

Just one morning.

The two tables of account books and the entire Funing County account have been basically checked and are coming to an end.

Moreover, Funing County belongs to the Great Wei Dynasty, so the workload is not small.

Among them, Qin Yu's simple numbers contributed a lot, and Xiao Nan's oral calculation also contributed a lot.

Xiao Nan's oral computing ability is really strong. No matter how complex the numbers are, they can be accurately calculated in just one breath.

It is faster and more accurate than abacus.

This is really Xiao Nan’s talent in mathematics.

Not far away.

Qin Wenyao saw Qin Yu who was lying on a chair and taking a nap, and his anger suddenly surged.

He asked Qin Yu to come to the Ministry of Revenue to help.

This is a good thing. Prince Xiao Nan and Shen Binglan were busy working hard, and he was actually sleeping there.

"This bastard is really in need of trouble!"

Qin Wenyao brows deeply and walked towards Qin Yu in a low voice.

Qin Yu was leaning on the chair and closing his eyes to rest, when suddenly he felt the murderous intention sweeping towards him.

He hurriedly opened his eyes and looked.

I saw Dai Yi’s father coming to him angrily.

Qin Yu hurriedly stood up from the chair, saying, "There is no good person to come!"

"Qin Yu! Are you going to piss me to death? I asked you to help, not to sleep!"

Qin Wenyao walked forward, pointed at Qin Yu and cursed.

at the same time.

The noisy hall became quiet in an instant.

Everyone's eyes fell on Qin Wenyao and Qin Yu, the father and son.

Qin Yu's brows froze and said lightly: "Dad, you are so angry that you are so angry to relieve your anger."

"Disease!"

Qin Wenyao glared at Qin Yu, "Look at the style! Can I calm down? The prince is working here, you sleep there, who do you think you are?"

Qin Yu explained: "Dad, the accounts of this county have been settled, and there is no place for me to use."

Hearing this.

Qin Wenyao was stunned, then furiously said, "Nonsense! You are the account books of a whole county, how could you finish the right way so quickly?"

Qin Wenyao is the Minister of Revenue. He knew how much work he had sent to Qin Yu and Xiao Nan. If Qin Yu, Xiao Nan and Shen Binglan alone, it would probably take three days.

Even if Qin Yu asked two more officials for help, it would take two days.

But now just half a day has passed, Qin Yu has finished speaking, and Qin Wenyao doesn't believe a single word.

The eyes of the officials in the hall also fell on Qin Yu.

at the same time.

The books in the hands of the two sly officials are gone.

Xiao Nan completed the mental calculation.

Shen Binglan also finished the last word.

"Mr. Qin, we...we have indeed checked and summarized it."

Xiao Nan looked at Qin Wenyao and said seriously.

The simple numbers developed by Qin Yu really made Xiao Nan's oral computing ability more powerful.

Xiao Nan felt that he was almost flying, and he was enjoying it.

"The checking and summarizing it up?"

Qin Wenyao looked at Xiao Nan, his eyes full of surprise.

Shen Binglan handed over the checked and summarized books in his hand.

In fact, the account of the Ministry of Revenue did not have to be so troublesome, because the prefectures and counties below have already been settled.

However, Qin Wenyao insisted on the Ministry of Revenue to conduct secondary verification and summary, and even checked on the town unit.

Because only in this way can the Ministry of Revenue analyze the tax payment amount in each town, which is normal and whether there is any corruption or abuse of power.

This has increased the workload of the Ministry of Revenue.

Qin Wenyao took the account book and looked at the simple numbers densely packed on it, like tadpoles. He was stunned at first, then shocked, and asked, "This...what is this?"

If this thing was not made by Shen Binglan.

Qin Wenyao almost thought they were fooling him.

But Shen Binglan would never do such a thing, and would not be in the same vein as Qin Yu.

Xiao Nan hurriedly explained: "This is a simple number developed by my brother-in-law. Using this to calculate it is simple, clear, efficient, and really easy to use. We calculate it so quickly because my brother-in-law has just developed this thing."

Qin Wenyao: "???"

He looked at Qin Yu with amazement, not understanding what simple numbers mean.

The officials around him also showed curiosity when they listened.

What the prince-consort has studied is worthy of in-depth discussion.

Qin Wenyao looked at Qin Yu and asked, "Yu'er, what's going on?"

Seeing that things had turned around, he even changed his name to Qin Yu.

After all, the credibility of Qin Yu's research is still very high.

The officials also came over involuntarily.

Qin Yu explained: "This is a simple number, which can be replaced by one, two..."

Then, he explained the use of Arabic numerals to Qin Wenyao and a group of officials.

Listen to Qin Yu's explanation.

Qin Wenyao's eyes widened.

The officials of the Ministry of Revenue were even more amazed.

They were shocked by the easy calculation of simple numbers and were shocked by Qin Yu's talent.

In such a short time, just because of the complexity of accounts, the prince-consin developed a complete set of effective digital systems with his backhand.

this......

This is simply a stroke of magic.

This is an unparalleled talent in the world and shocking the past and present.

If laziness can show such talent, then the laziness of the prince-consort may not be bad.

Now everyone understands why the prince consort is lying there and is still working so hard.

There is no way, the prince consort's ability is really convincing.

Qin Yu looked at Qin Wenyao and whispered: "Dad, don't be so angry, it's not that my child is not working."

Qin Wenyao glared at Qin Yu, "Boy, there is such a good thing, why don't you take it out earlier? I have to delay my Ministry of Revenue for so long?"

Qin Yu explained: "Dad, you are making things difficult for the child. The child is also suddenly enlightened, right?"

Qin Wenyao said again: "Then why didn't you take it out earlier just now?"

Qin Yu said: "If I don't take practical actions, can you believe me? I guess it would be good if I didn't say I was taking shortcuts. I don't know you yet?"

Qin Wenyao was very rigorous about the accounts of the Ministry of Revenue.

These days, he has been in the Ministry of Revenue for food and accommodation, just because he is afraid that the accounts will go wrong. Especially this year, the first year when the Great Wei completed agricultural and tax reforms and the tax revenue soared. He cannot count a penny, otherwise he will be sorry for the people of the world's contribution to the Great Wei.

Listening to Qin Yu's words, Qin Wenyao also lost his words.

Qin Wenyao brows frowned, "Hurry up and popularize it! Accelerate account verification and summary!"
