The moonlight is quiet, shining through the west window and sprinkling on the private room of this drunken fairy building.

At this time, the atmosphere in the room is very solemn.

Lao Zhu was holding a lit cigarette in his hand, Ah Biao was sullenly drinking his elixir wine, Zhu Laosi was frowning and contemplating, only Xiao Zhu Si grabbed a cigar and smoked violently.

Young people are addicted.

"I'll ask you one more question."

Ji Boying's voice broke the solemn atmosphere.

"How long can an emperor sit on the throne on average?"

As soon as this question came out, Ah Biao and Zhu Di were stunned, and they kept their mouths tightly silent one by one, they didn't dare to answer this question, after all, there was only one emperor present, and that was Lao Zhu.

Even if it is Zhu Laosi, he has not yet sat on the throne in the Jianwen time and space, but is just a regent.

"Hmm... About thirty years. ”

Lao Zhu thought for a moment and gave his own answer.

Obviously, Lao Zhu is very pragmatic about lifespan, unlike those emperors in history who are full of thoughts about immortality, Lao Zhu clearly understands that everyone has a limited day, and the Son of Heaven is no exception.

"Five years."

Ji Boying said lightly.

'Five years?! ’

'So short?! ’

This number really surprised several people.

"Of course, this number is the average count of all emperors who have reigned since there was an emperor."

Ji Boying, who has been sensitive to numbers since childhood, remembers very well that from the first emperor Yingzheng to the last Puyi, there were 495 emperors with honorific titles, and 73 people who were posthumously awarded after their deaths were removed, and there were 422 emperors who actually reigned, and the time limit for the existence of the emperor's post was 2137 years, on average, the time for an emperor to sit on the dragon chair was only a short 5.063 years.

At that time, this figure was an average of all dynasties.

"In the Ming Dynasty, the average reign of the emperor was seventeen years."

This number is also very easy to calculate, the Ming Dynasty has been in the past 276 years, and the sixteen emperors have been in the calendar, and the answer can be obtained on average.

When he heard the number 17, Lao Zhu still felt a little relieved, after all, compared to the average number of 5, his 17 years of Daming have more than tripled.

"Brother, I don't know what these numbers mean?"

Lao Zhu listened very seriously, didn't even smoke the cigarette in his hand, and was thinking about it very seriously, but he still didn't understand what the relationship between these numbers was.

Zhu Biao and Zhu Di also looked at Ji Boying with a puzzled expression, waiting for Ji Boying's answer.

"I ask you, if an emperor dies, what is the one thing that must be done after his crown prince ascends the throne?"

Ji Boying continued to ask.

Giving the answer directly, that is not Ji Boying's original intention, just as he left a question during the day, it is better to teach people to fish than to teach them to fish, he wants to exercise the thinking ability of the ancestors of the old Zhu family, and pass it on.

"Naturally, it's an amnesty."

Almost without consideration, Zhu Biao blurted out.

The new emperor ascended the throne and granted amnesty to the world, which is indeed a common practice.

Lao Zhu has no answer, he has never been a prince in his life, he is an emperor directly, how do you know which thing must be done after the prince ascends the throne, anyway, the first thing he Lao Zhu did when he ascended the throne was to set the capital.

As for Zhu Laosi, he thought to himself that even if he ascended the throne, it would not be from the position of the crown prince.

And Xiao Zhu Si, now he has never been an emperor at all, of course, he doesn't dare to think about it.

"When the crown prince ascends the throne, he must canonize his sons as princes."

Ji Boying's words came out, and several people were stunned for a moment, the brain CPU was spinning rapidly, everyone was smart, and combined this sentence with what Ji Boying said before, and suddenly collided with a spark of wisdom.

"What the immortal master means is that it takes more than a hundred years for the descendants of a prince to pass on to the idle clan, and every 17 years, there will be several or even more than a dozen princes, so if the fission continues, the imperial court's finances are still unaffordable."

Zhu Biao was the first to speak, and he understood.

At this moment, he felt that the sky was high and the clouds were wide, and the world suddenly became clear.

"That's a good answer."

Ji Boying glanced at Zhu Biao, and then swept over Lao Zhu and Zhu Laosi, and saw the gradual realization in the eyes of the two of them, so he didn't explain too much.

After all, there are too many unpredictable factors in the concretization of the fission problem of the number of people, although it can also be roughly calculated by mathematical multivariate equations, but this process is too troublesome.

As for Xiao Zhu Si, let this young man slowly realize himself.

"Taking the change in the number of people as a variable and the total cost as the result, this process is difficult to control, because it is impossible to control the fertility of each generation of clans, as well as the overall fission rate of the number of people, these factors will affect the increase of the entire base."

"Therefore, we need to change our thinking and change the perspective of thinking about the problem from "number of people fission" to "sample cost".

"Instead of using the change in the number of people as a variable to calculate the total cost, we should use the sample cost as a quantitative to calculate the total cost."

"Variables are uncertain, and quantification limits the range."

"Listen, I'll just say it once."

Ji Boying's knuckles tapped on the table, including Lao Zhu, they were all concentrated, and they didn't dare to fall asleep for a moment, they could all have a hunch that this was a profound knowledge.

"Cheer us up, if anyone dares not listen carefully, let's hang him up and smoke."

Lao Zhu reminded him fiercely, and his sons were so frightened that they were scared.

"1. The annual salary of the prince will be reduced to 10,000 stones, and the hereditary replacement will be cancelled.

After Ji Boying finished speaking, he paused slightly.

He knew that someone had questions to ask.

"Immortal Master, can you explain in detail, this Yulu is divided by the upper level, what is the division?"

Zhu Laosi frowned, his mood was very excited, because this trip was not in vain, and he felt that several major problems that plagued him were about to be solved.

Immortals are worthy of being immortals, and the disturbance of mortals, immortals only say a few words.

"yes, we want to know."

Lao Zhu also nodded and snorted his cigarette fiercely, he felt that he had understood, but he didn't seem to fully understand.

"I'll give you an example."

Ji Boying said, and as if he had a trick, he had an extra handful of fried chestnuts in his hand, and peeled them and ate them by himself.

"The prince's annual salary is 10,000 stones, if he has two sons, these two sons and the crown queen attack the king of the county, the two sons each have two grandsons, these four grandsons and the crown queen attack the general of the town country, the money is 2,500 stones."

"Generations to come, and so on."

"The distribution of the next generation can be based on the specific distribution of the eldest and youngest, which can be discussed in practice, but the distribution amount will not change."

"Normally, by the time the fourth generation of children and grandchildren arrives, the first generation will inevitably have died out."

"Therefore, calculated in three generations, no matter which generation of descendants it is passed onto, the court only needs to pay a maximum of 30,000 stone taels per year for the children of the same prince."

"This 30,000 stone is a quantitative."
