"In fact, the best way to control the locust plague is to turn over the soil in the dark and damp places in the fields before the locust plague has formed, and let the soil be exposed to the sun, so that the locust eggs can be sunburned to death! The eggs of locusts are sunburned to death, so naturally there will be no locust plague! ”

"Why?" Zhao Kuo naturally understood what Qin Yu said, but he didn't understand why he had to turn over the soil in those fields.

"Because locusts like to lay eggs in that kind of place!" Qin Yu said naturally.

"Qin Yu, why do you know where locusts like to lay eggs? Do locusts lay eggs? Zhao Kuo asked in confusion.

In his mind, the formation of locust plagues was not caused by locusts laying eggs, and he didn't even have this concept! Whenever there is a plague of locusts, it is the locust god who spreads his people to the heavens and the earth, which is the punishment of the heavens for the unvirtuous king!

"Locusts don't lay eggs, so how do they reproduce?" Qin Yu was asked by Zhao Kuo's question and laughed.

"Didn't they live and die at one time, and finally return to the arms of the locust god?"

Zhao Kuo's answer made Qin Yu stunned for a moment.

What Zhao Kuo replied just now, after he said this, Qin Yu understood what the situation was!

Zhao Kuo, or rather, no one in the entire Later Qin Dynasty understands how locusts reproduce their offspring!

"His Royal Highness the Prince, if it is really as you said, then what else are we talking about controlling locusts?"

Zhao Kuo was also stunned, it seems to be such a reason!

If the occurrence of the locust plague was spread to the world by the locust god, then what was the use of him looking for Qin Yu? If Qin Yu had a countermeasure, wouldn't it be said that Qin Yu was also a first-class immortal?

For a while, Zhao Kuo felt that his thinking was a little confused!

After a few breaths, Zhao Kuo shattered the mixed thoughts in his mind, now is not the time to think about this kind of thing, the most important thing now is how to stop the locust plague.

"Captain Qin, now that you know how the locust plague is formed, is there a solution?" Zhao Kuo is the cultivated prince after all, and when he asks about business, his aura has changed a little.

"The last general does not dare to have any guarantees!" Qin Yu said this in a bare manner.

He doesn't know how big the locust plague is, how big the disaster is in the three provinces and one state, I'm afraid Zhao Kuo doesn't know either, and he doesn't have any confidence that he can control the locust plague.

If Zhao Kuo can believe him, then he will say that if he is cured, it will be regarded as a credit, but if he can't be cured, he will also be vaccinated in advance, and Zhao Kuo or the emperor Lao'er can't trouble him.

Zhao Kuo was entangled in Qin Yu's words, he gritted his teeth and said, "But it's okay to say it!" The worst thing is a void! ”

Qin Yu got Zhao Kuo's assurance, and then he spoke: "If the locust plague is smaller, it can actually be controlled by manpower?" ”

"You mean people to catch locusts?" Zhao Kuo looked at Qin Yu with a slightly ugly face, he waited for a long time, looking forward to the result for half a day, is this?

If that's the case, does he still need to listen to Qin Yu?

Whenever there is a locust plague in a place, the local people will spontaneously rush into the fields to drive away, light fires and smoke, and the locusts will not only eat the crops, but also the lives of their families!

"His Royal Highness the Crown Prince, do you think you can rely on people?" Qin Yu also heard the difference in Zhao Kuo's tone, and asked a little funny.

Even if the locusts can't run or fly, just covered by a black and oppressive locust cloud, can you cope with it with a little manpower?

"And what do you mean?" Seeing that Qin Yu had a different opinion, Zhao Kuo hurriedly asked.

"Manpower is the auxiliary, in fact, the real main force, there are other things!"

Zhao Kuo saw Qin Yu selling Guanzi, and he couldn't wait to slap him to death, every time he delayed a few more breaths, wouldn't the people of the three prefectures and one state suffer a few more crimes?

"Speak quickly!" Zhao Kuo's tone became a little serious, and then he felt that his tone was too tough, so he explained: "Captain Qin, this matter is too hasty, and you can't take your time!" ”

"It's a duck! As long as enough ducks are gathered, a small-scale locust plague can actually be wiped out! ”

Qin Yu said that the method is naturally a biological control method, normally speaking, there will be this scene in nature, when there are too many locusts, some birds in nature will gather together, flocks to prey on locusts, and reach the effect of inhibition.

Now that there is a locust plague in three provinces and one state, it is naturally more difficult to rely on God to rectify it than to ascend to the sky!

But he can't rely on God, Qin Yu can still rely on the ducks raised in his hands!

When the locusts fly in the sky, it is tantamount to a fool's dream to rely on ducks to hunt the locusts, but when the locusts hit the ground, the ducks can go to hunt.

"Ducks?" Zhao Kuo looked at Qin Yu in confusion.

He felt that Qin Yu was playing with him as a fool!

What is a duck, can he still not know?

That kind of little thing that walks and sways, can still fly to the sky and eat locusts?

What do you do to dream of spring and autumn?

"Ducks eat locusts, and relying on them to eat is much more convenient than manpower."

Qin Yu's answer did not make Zhao Kuo half satisfied, and even a little annoyed.

"Captain Qin, don't be joking! How can the foot of a duck compare to that of a locust? As soon as the locusts fly, even if the ducks on the ground chase them desperately, I'm afraid they won't be able to catch up! ”

"Did you say that the ducks should chase the locusts?" Qin Yu replied with a smile.

"What does Captain Qin mean?"

"Of course, I'm waiting for the locusts to come, and then I'll let the ducks eat!" Qin Yu said seriously.

"Alas..."Zhao Kuo was speechless because of Qin Yu's words.

After gasping hard and calming down his emotions, Zhao Kuocai said in a serious tone: "Captain Qin, locusts are not people, they fly wherever they want, why are you waiting?" Even if you can wait, your name is the palace, where can you ask the imperial court to get so many ducks? ”

"Haha..."

Qin Yu suddenly laughed, which made Zhao Kuo feel like he was being teased.

His face also turned a little unkind.

"Your Royal Highness the Prince, you said that where the locusts are flying is not certain, we can't wait for them? This is not accurate, but in fact, can we wait for them? ”

"The principle is simple! When the locusts are finished in one place, they naturally have nothing to eat, so do they have to go to other places to find food, and since they are going to find food in other places, do they have to go to places where there is something to eat? Let's just wait for the rabbit! ”

"It's just that this way is relatively unreliable! But at least it's not powerless, you can only watch the locusts spoil the food! ”

"As for the question of whether the ducks can catch the locusts, it's actually very simple! As long as the imperial court can send troops, each soldier has one person and two horses, and immediately brings one or twenty ducks on his body, and chases the traces of locusts day and night, and finally can eliminate some locusts! ”

Zhao Kuo was a little stupid!

Can you still do this?

Listening to Qin Yu's statement, it is no less than the way the cavalry cruises in the march and battle!

If the locusts are regarded as enemies, the cavalry carrying the ducks is the long knife that destroys its living force, and the victory will eventually belong to the imperial court!

For a while, Zhao Kuo was impressed by Qin Yu, and even had some doubts about Qin Yu's evaluation in Lin'an City, whether it was intentional or not?

A person who can treat the little locusts as enemies, and everything he says and does is the art of marching and arranging, will he really want to blend into the circle of scholars?

"Relying on ducks to hunt for food can only eliminate a part of it, in fact, there is another way to eliminate some locusts."

"Speak quickly!" After Zhao Kuo heard what Qin Yu said just now, he had already decided in his heart that this method was feasible, and now Qin Yu still had countermeasures, naturally the more the better.

"That's a human catch!" Qin Yu said with no embarrassment on his face.

I don't know who just said that it is caught by manpower, and the birds are useless?

Zhao Kuo looked at Qin Yu a little dumbfounded, how could this person speak upside down? He who says no, he is the one who says yes, and he who says yes?

Zhao Kuo took a hard breath, suppressed the resentment in his heart, and asked, "How can you rely on people to catch it?" ”

"Use a net! What else can be used? ”

Even if Zhao Kuo has a good temper, after hearing this, he felt a little angry.

What is the difference between saying these words and not saying them?

Qin Yu also saw that Zhao Kuo's face was ugly, and he no longer wanted to tease Zhao Kuo, so he said: "Your Royal Highness the Prince, in fact, what the last general wants to say is not what you understand!" ”

Zhao Kuo snorted, and he didn't bother to reply.

"The last general's reference to relying on manpower to grasp literally really means relying on manpower to grasp! But it doesn't mean all that, it means something else! ”

"When people catch locusts, what will they do with them, has His Royal Highness the Crown Prince thought about it?"

Zhao Kuo said almost without thinking: "Of course, burn all the locusts to death with fire!" ”

The locust plague caused by locusts eats up the crops planted by the people, and the people naturally hate these locusts to the core, and it is difficult to understand the hatred in their hearts if they are not burned to ashes!

"Wrong!" Qin Yu shouted, shook his head and said.

"What's wrong? Do you have to let those locusts go? You know, locusts..."

Qin Yu interrupted Zhao Kuo's statement and said with a smile: "Your Royal Highness the Prince, those locusts have eaten so many crops of the people, and the people are already short of food, you just burned the locusts to death to vent their hatred, but the people have not been able to solve the problem of lack of food, so! Why burn the locusts you catch? ”

"Wouldn't it be better to give it to the people as food to eat?"

Zhao Kuo's face turned pale, and he was a little resistant to stay away from Qin Yu.

"Captain Qin, what nonsense are you talking about? Locusts are worms, how can they be eaten? It's so delicious, isn't it..."

Zhao Kuo is poor in some words, and he really can't find words to describe it.

"Why can't the locusts be eaten? Fry the locusts in the oil pot, fry it on the outside and tender on the inside, and then sprinkle some salt grains on it, not to mention the people who can't eat good salt, even the dignitaries and nobles in Lin'an City may not be able to eat it! ”

Zhao Kuo instinctively swallowed his saliva, and after reacting, he waved his hand again and again, feeling a little nauseous.

If they eat even locusts, then how are they different from animals when they are born as human beings?
