Datang: My identity as prince was exposed by Li Er

call!

Li Wan clapped her hands.

Looking at Shangguan Yi lying on the ground.

Feeling comfortable.

Shangguan Yi opened his mouth slightly,"Actually……"

"Um?"

Li Yi said solemnly.

Shangguan Yi was about to cry but had no tears, so he wailed:"What a sin! Sooner or later I will be played to death by you!"

Patted the dust on his butt and spat hard.

Shangguan Yi tidied up his clothes and ran directly to Chang'an City. I won't play with you anymore!

I'm going to do business!

Farewell!

Li Wan looked at Li Yi suspiciously and frowned. He asked with an eyebrow:"Why are you still here? Don’t know how to move out?

After thinking about it, Li Wan nodded and said,"Wait for me for two days.""

House prices in Chang'an are soaring now.

It's very difficult to buy real estate.

Li Wan owed a favor to the 'Shangguanyi' in front of her, and secretly decided to go to Chang'an tomorrow to look around and see if there were any extra properties that could be purchased.

In this way, He can also break free from the clutches.

Li Yi:

What's going on? I didn't say anything. Why are you just waiting for two days?

"The master's destiny is great. Recognizing the master is equivalent to recognizing the father. I...can't leave! Li

Yi sighed.

Li Wan's fingers rattled,"Haha, it's okay. When I kill him, you won't have a teacher anymore.""

Damn it!

Li Yi's eyes widened and he silently sympathized with Shangguan Yi for a second.

This child... is unlucky enough.

"No, don't cause trouble.

Li Wan shook her head and said:"Don't worry, I have a sense of discretion and I won't die.""

"……"

Li Yi looked at the breakfast on the stone table and asked Li Wan,"Let's eat something together?"

Li Wan nodded.

A bowl of hot porridge and a plate of gelatin.

The two of them ate with gusto.

Finally, Li Wan wiped the porridge stain on her mouth with her sleeve.

Li Yi quickly handed Li Wan the handkerchief.

"Something wrong!"

Li Wan rolled her eyes at Li Yi:"The scholar is angry. What are these sections for? When eating in the army, who doesn’t grab the food? If this were the case, I'm afraid I would have starved to death."

"But this is not the military, you... still care about it, it's disgusting"

"you!"Li Wan held her breath, reluctantly took Li Yi's handkerchief, and wiped it on her mouth again,"Are you satisfied now? Li

Yi thought for a while and said:"It's okay, but you shouldn't have a Hetian jade hairpin on your head. It's too asymmetrical.""

"you!

Li Wan angrily pulled out the jade hairpin from her head,"Are you satisfied?" Li

Yi nodded with a smile and said:"Look, this is much more pleasing to the eye. In the future, you will either not wear it, or you will have to wear it symmetrically, you know?" This will be pleasing to the eye."

I don't know when, Li Yi started to have some obsessive-compulsive disorder.

Maybe this is because the quality of life has improved. The overall style has also improved?

Li Wan gave him a hard look,"There are so many problems! Let me ask you something serious.

Li Yi nodded and said,"You tell me, I feel comfortable now. Just ask me anything." Li

Wan thought for a while and said,"Hey, do you think there is a way to find out some fraudulent accounts as quickly as possible?""

Seeing Shuyi and Xu Hui working so hard, Li Wan felt heartbroken, but was there any way to go to the Ministry of Household Affairs to help them?

"Benford's Law...ahem, yes."Li Yi blurted out without thinking.

"ah?"

Li Wan looked at Li Yi blankly.

She didn't have much hope at first, so she just talked to Li Yi casually.

But why did he say yes so easily?

Li Wan then said:"I just said It was not made clear that the false accounts were found from thousands or even tens of thousands of account books.

Li Yi nodded and said,"Yes, there is a way, and it's very simple. Children of any age can tell the difference.""

Li Wan:???

Do you want to be such a monster?

This problem has made the entire household department and all the big guys in the court, including Wei Shuyi and Xu Hui, at a loss.

Now you not only say you can solve it. You also say that a child of any age can tell the difference?

This That’s a bit disrespectful!

Li Wan excitedly grabbed Li Yi’s hand and said,"Tell me something."

Li Yi quietly rubbed the palm of Li Wan's hand.

Has this little girl learned to seduce people?

Li Wan blushed, glared at Li Yi fiercely, and quickly took his hand back.

Li Yi said with a serious face:" Ahem, if I want to understand the law of fraud, I have to ask you about a natural law first."

"In your opinion, among all the accounting data, what percentage of the total data is the number with one as the first number?"

Li Wan pondered for a moment and said,"I haven't looked carefully, but among all the numbers, the first ones are from one to nine. According to common sense, the first one is one, which should account for more than 10%.

Li Yi shook his head and said:"This is your expectation, but it is not the case.""

"In a bunch of data drawn from real life, the probability of numbers starting with one is about 30% of the total, which is nearly three times the expected value of 1/9. On the contrary, the larger the first number, the less likely it is to appear."

"I say this...can you believe it?

Li Wan blurted out:"How is this possible?""

Li Yi smiled and said:"I didn't believe it at first, but it is the truth."

"I'm asking you, do you think who will hit the ground first when a big stone or a small stone is thrown from a high altitude?

Li Wan said without thinking:"Of course it's a big stone."

Li Yi smiled and said:"You can verify it yourself when you have time. They landed together.""

Li Wan looked at Li Yi.

After a long time, she held back a sentence:"Nonsense!"

Li Yi ignored his doubts.

Just as he didn't believe in Benford's Law at first.

The so-called Benford's Law is also called the first law of numbers.

This number law was often used in the field of economics in later generations. Through this The law can detect digital fraud. In later generations, many listed companies’ false financial reports fell on this law.

Although this law seems counterintuitive and anti-human, it does exist and is based on big data. It has been proven that science is sometimes so unreasonable and unintuitive.

……

After Li Wan leaves, return to Li Mansion.

She was still doubtful about Li Yi's words.

If it was so easy to detect false accounts, what would the Accounts Department do?

"Dad, do you think who will hit the ground first if a big stone or a small stone is thrown together?"

Li Wan looked at Li Jing. This strange question suddenly came up, which made Li Jing confused.

Li Jing stared at Li Wan as if he was looking at an idiot,"Do you even need to ask? Of course big rocks!

Li Wan shook her head and said,"Will they land together?""

As he said that, he asked his servants to go up to the roof and start doing this experiment.

Once, twice, and three times.

Li Wan and Li Jing's eyes widened.

Li Wan felt a little creepy, and his hair stood on end.

"Oh my God! We really landed together! In this case, the account matter...can't be true, right?"

"If this is true, this guy is as smart as a monster! Li

Jing was also stunned, and then he saw Li Wan murmuring strangely:"Wan'er, what are you muttering about?"

Li Wan shook her head and said,"It's nothing. I'll go to the Ministry of Finance.""

"What? ? ? Li Jing said angrily:"You are not allowed to go."……"

But it's no use, the person has disappeared.
