King Jing completely trusted Li Yu, but it was no small task to deal with the locust plague. King Jing paused, held Li Yu's hand, and looked worried, as if asking him, are you sure?

Li Yu laughed and said: "Yes, but the means may not be very decent."

King Jing doesn't care about dignity. He is more worried about Li Yu's safety than whether he can stop the locust plague. Generally, people use fire to control locusts. Although many insects can be burned to death in a short time, there is also a danger of burns if you get close to the fire. Fish are carp spirits, so they are also afraid of fire, right?

Li Yu saw his worries and said, "Your Highness, don't worry, I won't go into battle in person."

Or it's not him who is going to fight, hey, don't think of him as a powerful goblin who can call wind and rain, he is just a system fish, and he himself is also very afraid of bugs!

Jing Wang Xu Xu watched Li Yu, seeing that he was really not joking, so he nodded and allowed him to try.

Li Yu begged for a pen and paper, and wrote a few in one breath. It was a coincidence. Before Li Yu passed through the book, some countries in the original world happened to be plagued by locusts. His country gave some help. Li Yu was curious. Next, I roughly studied how to control the locust plague. Although I don't remember everything, I think it is very interesting, and some of them are still fresh in my memory.

They are deep plowing, grain selection, and duck army.

King Jing:?

Li Yu tried his best to explain everything for him in a way that the ancients could probably understand: "Deep plowing means that locust eggs originally grow in the soil. When plowing, the soil is as deep as possible, and the eggs will be exposed to the sun." If you don’t, you’ll…be sunburned to death.”

"Food selection means that not all crops are eaten by locusts. If there are more grains that locusts don't eat, then there will be less food for locusts to eat, and naturally they will not be able to make trouble."

King Jing is smart and understands everything, and both of them are really interesting.

King Jing's eyes fell on the third item again. What is the duck army? Is it the... duck he thought of?

"Your Highness is right." Li Yu blinked, "It is said that ducks can eat locusts. The first two should be too late for locust disasters. Your Highness can get more now." Ducks, to solve the urgent need, this is called... Duck Army."

King Jing: "..."

King Jing frowned, what Xiaoyu said, especially the duck army, was unheard of.

But Xiao Yu's words sounded very reasonable, at least it was not burned with fire, and his life was not in danger, King Jing nodded slowly.

Some families in Luofeng Town raised ducks, not many of them, and they used to sell them for money and eat themselves.

King Jing ordered Wang Xi to buy some ducks. If ducks can eat locusts, let's try it.

Wang Xi took care of the job himself, went there before dawn in the morning, ran back within an hour, and said excitedly: "Your Highness, it's really useful! The old slave saw with his own eyes that the ducks would fly away as soon as they landed." I ate a lot of locusts, and the old slave has been eating them all the time, without stopping!"

Wang Xi rushed back to report the news, so happy that one of his shoes almost ran away.

According to Wang Xizhi's words, one duck could eat more than a hundred ducks in one go. King Jing made a rough estimate, and was a little uncontrollably excited.

At this time, if we first report back to the emperor, and the Ministry of Households allocates funds to buy ducks, the plague of locusts will be even more serious.

King Jing needed this opportunity, so Wang Xi let go of his hands and feet, and with the money of Prince Jing's mansion, first bought all the live ducks in the Western Territory. If the entire Western Territory was not enough, he would send people to nearby counties to buy them.

Li Yu came up with an idea again: "Your Highness, don't just buy the big ones, it's also good to buy some ducklings to raise. You can set up a place to raise ducks. The ducks grow fast and can catch up with the locust plague!"

King Jing thought, this is also a way, so Wang Xi followed suit.

A duck is not expensive, and King Jing has plenty of money. The people of Luofeng Town felt that King Jing had repelled the bandits, and when they learned that King Jing wanted to buy ducks, everyone who had ducks at home rushed to send them over, and many of them paid nothing. No charge.Nearby prefectures and counties heard that King Jing bought ducks to control locusts, and they were all very curious, so they made a fuss and sent the ducks to Luofeng Town in groups.

King Jing ordered the guards to meet him along the way to ensure the safety of the people who came and went, because he was afraid that the bandits would take advantage of the fire and rob them. However, the bandits heard that King Jing was going to control locusts, so they waited to see King Jing's excitement, and for the time being they didn't want to snatch a few ducks.

Wang Xi quickly collected [-] live ducks and nearly [-] ducklings.

The duck cubs still needed to be fed, so the live ducks formed a duck army and rushed to the worst-hit town.

King Jing also went there in person, and after one day, there were gratifying results. The duck army could really eat, and a small group of ducks could eat almost as much locusts in an acre of land in just half a day.

What troubled the common people in the past was that locusts did not live long. Even if they tried to burn a wave, they would grow back quickly and cause a fire. Now, there is no need to worry about it at all. Ducks can eat non-stop for several days. Other risks, and the loss is extremely low. When the locusts in a town are almost eaten up, the duck army will only lose less than [-]%.

Ducks are really amazing soldiers. King Jing smiled and gave Li Yu his thumbs up, and continued to ask Wang Xi to go around to buy ducks.

However, something unexpected happened in the second acquisition. Wang Xi discovered that some merchants knew that they needed ducks, and they bought a lot of ducks from farmers at low prices in advance, and then resold them to Wang Xi at high prices.

Wang Xi was so angry that he reported to King Jing. Li Yu himself didn't expect such a problem. The palace spends money to buy ducks to cure the locust plague for the common people. Some people make such black-hearted money with no conscience. If the locusts eat up all the food, where will they go to eat?

Really, if you give three times the profit, you dare not even die.

King Jing had been thinking about it for a long time, so he glanced at Wang Xi lightly, and asked Wang Xi to write down who they were, so that they could keep it and ignore it.

Wang Xi didn't buy many ducks this time, and was very worried that he might miss the job, but King Jing was confident.

It should be okay to buy chicken, right?King Jing looked at Li Yu.

"Chicken is also available! But chickens can be eaten without ducks..."

Li Yu nodded quickly, His Highness even knew this!

As long as King Jing can eat locusts, he ordered Wang Xi to also buy some chickens. On the other hand, King Jing also managed the duck farm run by Li Yurang. Using locusts as food, the ducklings grew extremely fast. Just when the duck army in front was about to fail, the ducklings grew up, and the duck army gave birth to a lot of duck eggs.

Li Yuxi said: "Fortunately, Your Highness bought a lot for the first time, and now you can continue!"

Wang Xitang is the chief servant of the palace. These days, he is only buying chickens and ducks and hatching eggs. King Jing smiled confidently and took over the latter. His Highness King Jing also knows about hatching eggs very well.

As for those who farmed live ducks, they couldn't wait for the high price of the palace to buy them, and gradually they couldn't continue to farm.

Ducks are living creatures, no more than food, they can be piled up in the warehouse, they have to be fed and looked after, if they are not careful, they will starve to death, and many escape.

Seeing that King Jing's Mansion no longer buys ducks, the ducks are dumbfounded, what to do with so many ducks?But besides Prince Jing's Mansion, who in Xicheng can afford to buy so many ducks at once?

These people were afraid of losing money, so they made a special trip to find Wang Xi to apologize. Wang Xi was reminded by King Jing, and he straightened his waist, so he pressed the price again and again, blowing out the bones of these people, and finally lowered the market price. It took a lot to collect these ducks.

Both the duck army and the duck farm are operating normally.Li Yu went to the duck farm run by King Jing, looked around, and made a lot of comments with the eyes of modern people. He thought the ducklings in the duck farm were cute, so he begged for two Huang Chengchengs on a whim. The ducklings are also raised in the yard where they live.

The fish cubs were as excited as the father Yu when they saw the fresh ducks they had never seen before.

Li Yu was afraid that the ducklings would eat the small fish, so he resolutely refused to allow the cubs to approach, and only allowed them to take a look from a distance.

Sibao likes pretty ducklings very much, one time when Li Yu was taking a nap, he secretly jumped out of the crystal bottle to play with the ducklings.

Speaking of naps, it is actually a habit that Li Yu developed after giving birth to cubs. It is said that when he was young, he slept a lot and developed well. Cubs take a nap together.

The fish cubs are all lively and active. When Li Yu woke up, they all got into the water plant quilt obediently with Li Yu. As soon as Li Yu fell asleep, the fish cubs got out of the quilt and played separately.

Four treasures and a fish just jumped out of the crystal bottle.Fortunately, King Jing had the foresight to lay a thick blanket on the ground just in case, and the Four Treasures fell to the ground without injury.

But Sibao was just a small fish the size of a palm, he completely forgot to leave the crystal bottle and the fish tank, he couldn't move an inch, and soon after landing, he felt uncomfortable.

Dabao, Erbao and Sanbao all swam to the edge of the crystal bottle, looking anxiously at Sibao fluttering.

Brother is in danger!

Dabao jumped out in spite of everything, followed by Erbao and Sanbao, and they all wanted to help Sibao.

As a result, only one cub of Sibao was flopping on the ground, but all four cubs flicked their tails.

Li Yu only took a short nap, and woke up from time to time to look at the cubs, and found that the cubs jumped out of the crystal bottle one after another.

Sibao was terrified and clung to Li Yu tightly.

Li Yu was both angry and distressed, so he couldn't blame this careless and confused cub, so he fed Sibao some fish food, trying to divert Sibao's attention.

Unexpectedly, Sibao was still clinging to him while gnawing on the fish food.

Li Yu: "..."

Li Yu wanted to know what happened to Sibao, so he teased Sibao to talk, but Sibao lisp: "Daddy, I want ducks!"

Li Yu guessed that Sibao wanted to see the ducks, but he fell to the ground.

Why does Sibao like ducks so much?

Li Yu thought about it, and took Sibao to see the grown-up duck with a smirk. Sibao saw with his own eyes that the mouth had grown a lot compared to when he was a child, and the neck had become curved and long. It was a tall and fat duck. Duck, think about the fluffy and cute duckling, and cry.

After Li Yu bullied Sibao, he went to bully Dabao again.

Dabao failed to save his younger brother, but caused himself and the other two younger brothers to fall to the ground. Dabao realized that what he did was wrong, and as soon as Li Yu came to him, he took the initiative to say to Li Yu: "Father, I know I was wrong. "

In fact, Li Yu also likes to stroll: "Oh, what is Dabao's mistake, can you tell Dad?"

"Yes... I was too weak to bring my brother back."

Dabao felt a little wronged and embarrassed.

Li Yu:? ? ?

Wake up, son, it's not your fault that you have too little strength, okay?

Dabao didn't know about Yu's father's complaints, and said very seriously: "I want to be the strongest fish, and I want to protect my younger brother and my father!"

Li Yu: "..."

Li Yu seemed to see the great pride behind Dabao. Really, it was obviously a small fish hatched from the same wave of fish eggs. Sibao couldn't speak well, but Dabao could clearly articulate a long list of wishes!

"Dabao is a good boy." Li Yu rubbed him with his fins to comfort him, and continued: "But remember to do what you can."

Dabao:?

Do what you can, what do you mean!

Li Yu taught him: "It is only when Dabao grows up that he can protect his father and younger brother."

Dabao nodded with a vague understanding: "Then Dabao must grow up quickly."

Li Yu: "..."

Emma, ​​although I think it's a bit exaggerated, but what's the matter with being warmed by Dabao inexplicably!

Thanks to the efforts of the Duck Army, the momentum of the locust plague in the western frontier has been brought under control. Although there are still relapses in some areas, according to the current combat power of the Duck Army, I believe it will not take long for the locusts to be completely wiped out.

However, after the locusts were wiped out this year, we cannot easily relax our vigilance in the future. The locust disaster will mainly recur, but now that there is a magic method to control the locusts, it does not matter even if it recurs in the future. A few ducks are gone.

I heard that ducks are a good thing. Not only can they be sold for money, they can be eaten, and they can also kill locusts!

How to deal with the last bunch of ducks who ate locusts and ate fat is quite a headache.

Seeing so many ducks, Li Yu's eyes lit up, he took a deep breath when he thought of something, and said to King Jing, "Your Highness, why don't we eat roast duck!"

King Jing: "..."

King Jing is a man who can eat cucumbers that Li Yu personally patted without changing his face or heartbeat, so what's the point of eating a mere roast duck?

King Jing nodded, and Xifeng Quan Jude had a prototype.
