Zhang Nan immediately stopped Xiao Yu, Xiao Yu is also a legend in the Tang Dynasty, serving as prime minister six times, and ousting the prime minister six times, and even expelled from Chang'an City in serious cases.

But this does not mean that Xiao Yu is talented in arithmetic. On the contrary, the legendary prime minister is an out-and-out liberal arts student, who is inherently insensitive to numbers.

Let him count things, it's really hard for him, not to mention that he is also old now, and his brain is naturally not as fast as when he was young.

didn't count Zhang Nan's question, Xiao Yu naturally couldn't talk nonsense, but he couldn't answer, and Xiao Yu was stunned on the spot for a while.

Comrade Lao Li also saw that Xiao Yu was a little embarrassed, so he could only hurry up to relieve Xiao Yu.

The reason why Xiao Yu was able to serve as the prime minister six times and dismiss the prime minister six times was entirely because he was too upright, and it was not good to say that there were some axes, so in order to prevent Xiao Yu from going down directly in the court, Comrade Lao Li could only personally relieve him from the siege.

"Qingquan, if you have anything to say, just say it." Comrade Lao Li said.

"The minister doesn't mean anything else, the minister means that it only takes less than fifty years for the population to usher in an explosive growth, and now it seems to be just a hundred acres of fertile land, but then it won't be the case, if you don't take precautions, there will be problems at that time." Zhang Nan said.

As soon as he heard that the population would grow explosively, Comrade Lao Li was immediately overjoyed, and for him, the more the population, the better, and the more the population, the more soldiers of appropriate age, and also the more soft power.

After conquering Goguryeo, Comrade Lao Li did not have the strength to continue attacking Tibet, but because the population of the Tang Dynasty was really insufficient, and moving some of the people to Goguryeo was already squeezing toothpaste.

If Tibet is defeated again, Comrade Lao Li will not have so many people to occupy so much land.

The land without a population is completely different from the terra nullius, just like the Turks, although Comrade Lao Li has brought down the grassland, but Lao Li does not have enough population to manage it, which is why the Western Turks are still jumping on the grassland very happily.

Now that Zhang Nan suddenly said that the population of Datang will usher in explosive growth in the next few decades, how can Comrade Lao Li not be happy?

"Qingquan, what you said is true?" Comrade Lao Li asked with some excitement.

"That's true, if the emperor thinks that there is a problem with what the minister said, then you can ask Master Cui about the household registration of Chang'an City, let him count it, and then roughly calculate it, this data is not difficult to come out." Zhang Nan said.

As soon as Zhang Nan said this, Comrade Lao Li immediately turned his face to Cui Shao, and then said: "Cui Aiqing, I order you to calculate the population of my Datang in the next fifty years within three days, and report the number to me." Comrade Lao Li said.

Comrade Lao Li personally gave the order, Cui Shao could only give up, and at the same time, Cui Shao also made a hard note to Zhang Nan in his heart, isn't it okay to find trouble for him?

"Master Xiao, do you remember what the emperor said just now, this land has been nationalized, and the property rights of individuals are only for how many years?" Zhang Nan continued to ask.

"This is naturally remembered, seventy years."

"Master Xiao thinks that these seventy years are not enough?"

"Is seventy years enough?" Xiao Yu asked rhetorically.

Zhang Nan heard Xiao Yu's rhetorical question, but instead of answering Xiao Yu's question, he looked around the court, and then said, "Do you think that these seventy years are not enough?" ”

The courtiers did not speak, but the expressions on their faces betrayed them.

"Okay, since everyone thinks that these seventy years are not enough, then who thinks he can live for seventy years, raise your hand and let me get to know you."

As soon as Zhang Nan said this, everyone stopped talking, but began to think.

That's right, these 70 years of permanent property rights are indeed insignificant compared to them, but the people they are here are basically above 40, and this group of people with an average age of 40 years or older, let alone live for 70 years, is whether they can live for 20 years, that is all unknown.

"Yes, in seventy years, I'm afraid my grandchildren will die of old age." At this time, I don't know who said such a sentence in the team, so everyone's atmosphere is even more awkward.

is like Cui Shao, and now his grandson is only three years old, and it is a question whether Junyan and Zhen Zhen can live for seventy years, let alone him.

All the courtiers present were basically in the same situation as Cui Shao.

"So, don't think that these seventy years are very few, strictly speaking, these seventy years include three generations. One person's exploits benefit three generations, don't you adults think it's enough? ”

"I agree with what Qingquan said, although the fathers have made merits, and the children and grandchildren should enjoy a part, but this does not mean that they can live under the merits of their fathers forever for the rest of their lives, three generations, it is long enough, besides, if the family can't make merits for seventy years, then why should the court support their family idlers?" Cheng Yanjin also stood up and said at this time.

"Yes, the emperor, the minister also thinks so, although the seventy years seem like not much, but for a person, seventy years is enough, as far as the minister is concerned, after seventy years, the minister will already be a handful of loess, and if the descendants of the minister can't even buy their own land, then they deserve to starve to death." The eldest grandson Wuji also stood up and said at this time.

"That's true, seventy years is long enough, if you can't make merits in seventy years, then you really don't deserve to have these things, and the minister feels that these seventy years are a bit long." Fang Xuanling also stood up and said.

Zhang Nan's statement just now can be regarded as speaking to the hearts of these people, they are not afraid that their children and grandchildren will not have enough to eat, they are afraid that their children and grandchildren will only rely on their merits and wait for death, they are all proud people, and naturally they will not allow their children and grandchildren to be mediocre.

This property right for 70 years is also a disguised way to let the children of this group of nobles think about making contributions to themselves.

"Lord Xiao, I don't know this explanation below, Lord Xiao is still satisfied?" Zhang Nan saw that the wind direction of the court was falling to his side again, and he also asked with a smile.

"This ......" Xiao Yu didn't know how to answer for a while.

Seeing that Xiao Yu still had questions, Zhang Nan decided to ask Xiao Yu for death at one time, so that Xiao Yu could fully support him.

"How long does Lord Xiao know about the national ancestry of each dynasty and generation?" Zhang Nan asked.
