After I traveled through the book, my whole family overheard my thoughts and went crazy

Just him?

I really didn't expect that he could even make it to the palace examination.

Looking at his poor appearance in plain cloth.

This palace examination is open to everyone.

Especially these ministers in the court.

Apart from flattery, do you have any other skills?

As long as you open your mouth.

They will all applaud!

That's how you scream.

Why don’t you go to the market and set up a stall and sell your wares?

"I think that in addition to what the two brothers above said, we should also spray pesticides in time when the locusts lay eggs. We should start controlling them from the larvae. We can't wait until they grow up and eat the crops before we pay attention to them." Pei Qin said casually.

Liu Erbao listened to the two people complementing each other.

His originally smug expression suddenly fell a little.

"But if we use the method of spraying pesticides, in addition to killing locusts, we may also accidentally harm some beneficial insects, just like what Brother He just mentioned, some farmed frogs, they also live in the fields." Xie Ruofan retorted.

Pei Qin's expression darkened. This...he really didn't seem to have thought of it.

“Indeed, this is indeed a problem.”

"If those drugs can kill locust eggs, it means they are toxic to a certain extent. If they are sprayed in large quantities, the land may be polluted, which may affect the harvest of that year."

"But if we only spray a small amount, it probably won't have much effect on locusts with strong reproductive capacity, and it may even hurt other beneficial insects by mistake."

"This method is not feasible. It cannot be used. It cannot be used..."

Emperor Yuanwu couldn't help but frown as he listened to the discussions of the crowd.

Although they discussed intensely.

But what they said were all recorded in history books.

If this method is really feasible.

The ancients would have eradicated locusts long ago, and they would not have become a headache for people today.

It seems that the qualifications of this year's candidates are mediocre. They can only apply what is taught mechanically and cannot offer any constructive suggestions.

I am afraid that when they serve as officials in the previous dynasty in the future, they will all be people who go with the flow and are useless talents.

This student is really getting worse every year.

There is no real knowledge at all.

Emperor Yuanwu sighed helplessly in his heart.

When Liu Erbao heard Xie Ruofan's proposal being refuted.

I was secretly delighted in my heart.

Just now.

He moved his lips and wanted to add something, but his mind went blank.

Last night.

He clearly wrote down every single one of them.

How come I can’t remember a single word now?

Fortunately, he was prepared.

Liu Erbao looked around and took a step back without making any expression.

He secretly glanced at the cuffs. The white cuffs were densely covered with various words.

"Does anyone else want to add anything?" Emperor Yuanwu asked casually, having no longer held out any hope.

Lu Zhaolin, who had been silent all this time, slowly walked to the center of the crowd.

"Students think that in terms of locust control, we can start with the cultivated land. According to previous historical records, locusts generally occur in mountainous areas, forests, grasslands, low-lying areas and semi-arid areas. The climate and geographical conditions in these areas provide a suitable living environment for locusts."

"If we want to fundamentally solve the problem of locust reproduction and growth, we can plant different crops to change the composition of the swarm."

"For example, if we plant corn this year and other crops next year, the nutrients in the soil can be balanced through the absorption of the crops by the soil."
