Song Yi pretended to be busy on the side, but in fact, he pricked up his ears and listened to gossip.

Zhu Xi also found out that Song Yi was eavesdropping, and did not stop it, but was more interested in her as if she was interested in the drought in Henan.

Song Yi didn't realize that he was being noticed, and only tilted his head to think about things.

China has been a large agricultural country since ancient times. In all dynasties, it was plagued by locust plagues. Since ancient times, we have accumulated a lot of experience in pest control.

Ancient China is the country that suffered the most locust plague in the world, according to the statistics of Deng Yunte's "History of China's Famine Relief": the Qin and Han dynasties had locust plagues every 8.8 years on average, the Song Dynasty for 3.5 years, the Yuan Dynasty for 1.6 years, and the Ming and Qing dynasties for 2.8 years. In the oracle bone inscriptions of the Shang Dynasty, there are records of merchants guarding against locusts.

Xu Guangqi's "Removing Locusts" wrote: "The country does not accumulate livestock, and it is not prepared for the loss of people who are hungry." There are three causes of hunger: water, drought, and locusts. ”

The locust plague was one of the three major plagues in China (drought, flood, and locusts) that could not be solved for thousands of years. Just because of the long rule but could not eradicate the roots, in the end, the people even had superstitions, thinking that locusts are "divine insects", and built temples to worship. Xu Guangqi recorded: "In the fourth year of the Kaiyuan Dynasty, the big locusts in Shandong, the people sacrificed and worshipped, sat back and watched the seedlings, and did not dare to catch them"

And these are feudal superstitions, of course, it will not really be because the people build temples and sacrifices to solve the locust plague.

The traditional Chinese experience in locust control is that "it is better to catch locusts than to replenish locusts (young locusts), and it is better to dig eggs than to replenish locusts". Egg digging is to plow the river beach and saline land where the locusts lay their eggs. But then, some people discovered that digging eggs is not a complete strategy, and this can only be a symptom rather than a cure. Digging eggs can only reduce the number of locusts, but not the area of locusts, and the depth of the cultivated land is different, and the eggs of locusts are uneven, but it prolongs the time for locust control. As a result, the government later stopped simply poaching eggs. Adjust the control target to the 2~3 instar locusts that do not grow Akasaka, and it is best to kill them at this time, and when it grows its wings and can migrate, it will be troublesome. Therefore, all localities have focused on "not taking off" in the control of locusts.

However, these are all things that Song Yi saw from books. For as long as she can remember, there have been no more widespread locust plagues in China. This also depends on the country's large-scale development of water conservancy and scientific planting, coupled with the prevention of micro problems, early detection and early prevention, which can ensure that the people are safe.

Song Yi thought a lot, but he didn't interject abruptly.

The people sitting here are all smart people, she is a girl, and she dares to say some strange and confusing words, she can only be regarded as evil, and no one will praise her at all.

But she really couldn't bear to let the people of Henan encounter another locust plague. So, Song Yi could only be in a hurry, but he didn't have a chance to say it.

Zhenwang has been paying attention to this Song Yi, and after she heard about the drought in Chen Gongzi's hometown of Henan, she behaved very strangely.

So, after Song Yi poured the tea again, he opened his mouth and said, "You girl, why are you so soulless today?" Didn't Chen Gongzi just say that there would be a big drought in his hometown, and you were interested? Do you still have relatives and friends in Henan? ”

When Song Yi heard the real king ask, he pretended to answer, "Lord Wang, the slave maid is from the capital, how can there be relatives in Henan." It's just that when I was a child, slaves and maids liked to read idle books, and I once saw an ancient book that said that where water and drought alternately occur, there is a great possibility of locust damage. The slave maid just heard Chen Gongzi say that Henan had a big flood in the first two years, and there will be a big drought in the coming year, so she thought of what was said in the book, so she was a little worried."

But the slave and maid were soft-spoken, afraid that they would speak out and make everyone laugh, so they lost their minds. Please also ask the prince to punish him."

Song Yi's words surprised everyone in the pavilion.

Zhenwang also looked at Song Yi seriously, although he didn't know why she said that there would be a locust plague in Henan. But he didn't blame her, he wanted to punish her.

The real king couldn't see why, but Song Yi said it well, and it was a big matter, so he could only ask the doorman instead, "All the gentlemen are all highly talented, I don't know if you have ever seen a similar record?" ”

Everyone shook their heads and sighed, except for Song Yi, no one had seen it.

Also, although these people boast of being well-read, they are all readers who can't pick and choose, so where are they interested in crops? No one will read these idle books.

The true king didn't get an answer, but he trusted Song Yi very much for no reason.

The real king didn't say anything, but there was a bookworm in the seat, known as Gu Laosheng, who was already ancient, and still participated in Enke, but he repeatedly fell to Sun Shan. He is not like others who are suspicious and disdainful of what Song Yi said, but he is curious about knowledge and is not ashamed to ask.

"Although the old student has read books all his life, he also knows the truth that books are endless. Although I haven't read the idle books that the girl said, and I haven't heard about the locust plague, the girl next to the prince will definitely not lie. I just don't know if the girl remembers the title of the book? If you can remember, let me go back and find it, and then check it. After all, this is a big matter related to the people of Henan, so you can't be sloppy."

Song Yi was asked so solemnly, and she didn't know how to explain it for a while, so she couldn't tell her that she saw it from Xu Guangqi's "Removing Locusts".

Xu Guangqi is a person from the Ming Dynasty, how can he be known by the people of the Qian Dynasty?

Song Yi could only pretend to forget the title of the book, and casually found a reason to prevaricate.

Although Song Yi couldn't name the book, and his credibility was greatly reduced, everyone in the pavilion finally turned their attention to the locust plague that they were not sure if there would be.

Among them, the most active is Chen Gongzi. He originally wanted to curry favor for the people in his hometown and let the true king apply to the court for disaster relief funds.

But now that I heard that there was a great drought in Henan, there was a very likely locust plague, so I also seriously asked for advice, hoping to pool everyone's wisdom and discuss the countermeasures of the ugly Yin.

However, these disciples of the true king are also dead books, and it is easy to let them recite poems against them, but there is no good way to let them come up with countermeasures to control pests.

But, as the saying goes, "three stinkers beat Zhuge Liang". Among them, some people said that quicklime can be sprinkled on the ground to get rid of insect pests.

What's more, it is said that people can catch insects to eat and make up for the losses caused by insect pests.

In short, there is everything to say. Everyone chatted happily, and soon it was dark.

The True King left the people to eat a sumptuous meal, and then let them go home.

Although everyone spoke freely just now, not many people really took a girl's words as true.

It's just that he has the heart to show off his knowledge in front of the true king.

But among them, there is still one person who is very shrewd and always feels that today's things are not simple. So after going back, he immediately recorded all the things in the pavilion that day and sorted out a codex. Although I did a lot of work, I didn't know what to do, so I still put it on the shelf.

Since that day, no one has spoken of the day's events. It's just that when the spring of the next year begins, Henan is really in drought, and locusts have also been found in many places.

And that's what came after.
