The reason why Luo Yan reached out to Li Shimin to ask for this and that was actually something he saw on the exchange page of the system by chance, so he came up with such an idea. Pen ~ fun ~ pavilion www.biquge.info

One pound of potatoes, one million prestige points.

That's right, under the strict historical trend, potatoes were not introduced to China until the Ming Dynasty. It's hundreds of years away.

But after Luo Yan saw such a thing, he couldn't stand it with excitement.

How poor was the productivity of land in the Tang Dynasty? As we all know, the yield per mu of hybrid rice is at least six or seven hundred catties. Some lands with suitable climate and strong soil fertility are said to have a normal yield of 1,000 catties per mu. It is said that an adult eats no more than 300 catties of rice every year, which means that today's mu yield can fully feed two people.

But there were no such good things in the Tang Dynasty, farming methods, irrigation methods, and fertilization methods, which greatly limited the productivity of the land in the Tang Dynasty. According to historical records, the yield per mu of more than 330 catties in the Tang Dynasty was a very good yield. But at the same time, there is a problem, such a production is also very demanding on the environment.

The output of this acre of land is basically enough for an adult man's living needs for a year. But don't forget, there's also taxes. All kinds of taxes are paid once, and basically even a man's food is not enough.

This also says that in the best case, if there is a drought or flood, it can be remedied earlier, and some losses can be recovered. Once a drought or flood occurs when the ears are set immediately, basically there will be no harvest. And that's not all, there are insect infestations like locust plagues. In this way, in fact, this kind of land basically depends on the sky for food.

The reason why Luo Yan was so excited when he saw a potato was because of this. Compared with grains, potatoes have lower requirements for natural conditions, and are not immune to insect infestations, even without fertilizer, the yield is much higher than that of rice.

In later generations, there were potatoes with a yield of 2,000 kilograms per mu, of course, that was achieved through scientific management. Now Datang still doesn't have this condition. But one thing Luo Yan is very clear, potatoes are definitely a lifesaver at a critical time.

However, the value of a potato has reached one million reputation points in the exchange system. Yes, you read that right, a full million reputation points for a fist-sized potato. Luo Yan didn't have a choice.

He is familiar with the trend of history, and naturally knows that in the first three years after Li Shimin seized power, there were many droughts, floods, and locust plagues. Some ill-intentioned people directly said this and spread rumors that Li Shimin's throne was improper, and they were punished by God. This caused a lot of boiling in the country, and many careerists took advantage of this to rebel, and the people's livelihood, which had just been quiet for a few years, was almost destroyed again.

I don't care about how Li Shimin scolded Luo Yan.

Although he has now taken refuge in Li Shimin's subordinates, this does not mean that Luo Yan will be Li Shimin's royal literati and advocate for him. It's just a matter of watching others do such a disgusting thing, if Li Shimin really wants him to do it, Luo Yan will definitely refuse without hesitation.

Luo Yan cares about the people at the bottom.

It's not that Luo Yan began to be compassionate after reading the book for a few days and became a saint. As a good young man from the new society, Luo Yan himself felt that since he could easily do something and help so many people, why not do it. It doesn't hurt anyway, does it?

Speaking carefully, this disadvantage is not without it. After all, if you exchange a potato, that's a million reputation points. Use these to exchange silver coins and convert them into gold, and you can mint dozens of solid potatoes.

There is such a thing in the system, and Luo Yan naturally will not let it go. What Luo Yan needs to worry about now is the source of this prestige value.

Since the fight in July, Luo Yan has not appeared much in front of people. The articles and poems written in the past, as everyone sings, the prestige that should be earned has already been earned. In three months, this reputation value was only about 100,000 yuan before, and it was exchanged for money by Luo Yan. Therefore, reality forces Luo Yan to earn enough prestige by the beginning of spring next year.

Although it is too little to exchange for a potato, Luo Yan also has a full plan, that is, to make a greenhouse.

In fact, greenhouses have existed since ancient times, and vegetables grown in greenhouses have appeared in the Han Dynasty. Luo Yan seems to want to take advantage of this and strive to get the number of potatoes to be mass-produced within three years. In any case, when disaster strikes, more preparation can at least reduce the number of deaths.

Some people may have questions about how much a potato can be transformed in three years. Three years and six stubbles, no matter how you say it, you can make seeds that can reach tens of thousands of catties. Coupled with the existing national reserves, then by the time of those three years, the last difficult period, these potatoes will be enough for disaster relief.

Luo Yan naturally took it for granted, there was no way to avoid this, but it was still guaranteed to relieve the pressure of disaster relief and keep the victims alive.

As for the maintenance funds of the greenhouse, Luo Yan also thought about it, anyway, there were not so many potatoes for them to get at the beginning, and when the time came, they would plant some out-of-season vegetables and sell them, at least they could return to their capital.

As for the future, I am afraid that Li Shimin will know what Luo Yan has done, and he will ask for the door himself without Luo Yan saying more. Ask Luo Yan to expand the scale of potato cultivation.

Imagination is good, of course, but the biggest problem at the moment is prestige.

Seeing that Li Shimin still gave him all the things he wanted, Luo Yan was also very satisfied. At this time, the part that contributes money and effort has been done well, so it is left to continue to show off and earn prestige.

On that day, the gathering of the Literature Museum ended in mixed feelings.

On the way back, several people who had known Luo Yan earlier came together.

"Yu Zhonglang, what do you think of today's incident?" It was Li Xuandao who asked. As the person who has the most contacts with Luo Yan except Lu Deming, Li Xuandao is also very puzzled by Luo Yan's performance today.

"Are you talking about his arrangement for you and me, or is it about asking King Qin for something?" Yu Zhining said with a smile.

"Both, of course." Li Xuandao pretended to be dissatisfied.

"Then the first thing is for me to answer for Master Li." Before Zhining could speak, Gai Wenda interjected: "Actually, Luo Yan is to give the two of you a meritorious service." ”

At this moment, Li Xuandao was a little confused. Although he is the head of the Qin Palace, and he has a lot of experience in political struggles, it is precisely at this point that he is dizzy.

"Think about it. You are the master of the royal house. If the saints want to expel us, you won't be able to escape. Especially the core of you, who served in the Qin Palace, when the time comes, you will be given an idle position, and you will not be able to do anything. After all, we are literati, unlike those military generals, who still have the strength to do it. At that point, I won't be able to wait for anything. But it's different for Luo Yan to arrange you to Chang'an County, as long as you don't make mistakes in the early stage, the saint can't do anything about you. At that time, even if you only control part of the rights of Chang'an County, you can play a key role in the struggle at that time. ”

"Brother Gai is only talking about one side. Actually, it's also about protecting us. At that point, King Qin wanted to do it, how could the prince not want to. Yu Zhining leisurely said the most terrible thing he could think of.

After a moment of silence, Kong Yingda broke the solemn atmosphere: "Let's think about the matter of Kid Luo Yan asking King Qin for something tonight." It's useless to think about that, you just know it's okay anyway. ”

"I think so, Luo Yan's actions today are afraid that he will defile himself." Kong Yingda is very optimistic about this young man.

"Why do you say that, it seems that he is not in a high position, so there is no need for this." Gavinda wondered. is also a Confucian scholar, he feels that his status is much higher than Luo Yan's in the Qin Palace, and even then he did not use such means as self-defilement.

"You see only the present, but you don't see the future. His idea for tonight was spoken with confidence that he would win. "Kong Yingda is a little unfathomable.

"I see, do you mean that what he said tonight will surely be fulfilled in the future. And he did something like tonight in order to prevent the light from shining too brightly after success in the future. At that time, even if King Qin wants to reward him again, we people will stop him, so he will naturally not be suspicious of His Highness. Li Xuandao patted his head and seemed to understand.

"It's not going to be that great, he's a teenager. It's terrible to have to prevent things even a few years from now. Gavinda exclaimed.

But these people didn't think of it, in fact, Luo Yan didn't mean this at all.

After coming back to their senses, these people began to carefully review what Luo Yan said tonight, and the more they thought about it, the more they felt that Luo Yan was much more powerful than other peers.

However, Kong Yingda laughed: "Actually, Luo Yan is also self-defeating tonight." You see, a few of us can think of it, let alone a few others. As for His Highness, even if he can't figure it out himself, there is still his brother-in-law to help. So, let's have a good show in the future. ”

No way, Kong Yingda naturally likes to watch the excitement. is self-defeating like Luo Yan, or a young man he admires more, so there are not many opportunities to make a mess.

As for the other people, after listening to Kong Yingda's words, they looked at each other and were stunned for a moment, and then laughed. I don't know whether to laugh at Kong Yingda for being disrespectful to the old, or laugh at Luo Yan himself for making jokes in the future.

Of course, Luo Yan didn't know all this. Sitting in the car, he was being taught a lesson by Old Master Lu Deming at this moment. The reason is that he rashly asked Li Shimin for something today, and he didn't discuss it with him. Regarding the future of his disciples, Lu Deming was also a little angry with Luo Yan's behavior.
