Datang: Signed in for Seven Years and Was Exposed by Empress Changsun

He even saved the life of Empress Changsun, and was granted the title of Wannian County Marquis at a young age!

No wonder my father asked me to dress up a bit before coming here, the future of such a young man is limitless.

"Miss Du is too polite."

Li Hong returned the salute slightly and let the two sit down.

"Master Li Hong, I'm here to ask for advice."

"Your Majesty said that you came up with the solution to the locust plague?"

Du Ruhui got straight to the point.

He looked at Li Hong with some horror.

Thinking that the ingenious plan came from Li Hong, I felt a burst of shock.

"Yes, is there a problem?"

Li Hong nodded and said.

He didn't know that after Li Shimin left here, he went back to Xiande Hall and pretended to be coercive.

I don't know if Du Ruhui hadn't asked about Li Shimin, Li Shimin wouldn't have said that he came up with the method.

Thinking that there was something wrong with his own method, he attracted the prime minister of the empire to correct him.

"No no."

"How can there be any problems with such a wonderful plan?"

"It's just that I don't understand a few things, and I want to ask the genius doctor Li Hong to give some pointers."

Du Ruhui waved his hands repeatedly.

Just kidding, how dare he say there is a problem with such a clever plan?

Looking at the entire imperial court, no one could think of such a method, how could he dare to rely on the old to sell the old.

"Just ask, tell me everything."

Li Hong stretched out his hand and spoke in a gesture of invitation.

"The old man would like to ask, what do locust eggs look like, and how do you find their nests?"

Du Ruhui sat upright and asked seriously.

"White with a yellowish color, they are usually produced side by side in the soil, about half the size of a little finger..."

"As for how to find their old nests, you can let people observe where most of them rest, or ask more experienced old farmers."

Li Hong thought for a while and said.

"Ask an experienced old farmer?"

Du Ruhui was a little puzzled.

"That's right, even though they are not educated, they are full of experience and can give you a lot of useful advice."

"They plow at sunrise and rest only at sunset. They see a lot more than they learn. It is right to ask their opinions."

Li Hong said in a deep voice.

The opinions of those old farmers could not be conveyed to the imperial court.

But if people from the imperial court ask in person, there will be great gains.

"It turned out to be like this. I would like to ask, how do you know this?"

Du Ruhui nodded with understanding, and lamented that Li Hong really saw it deeply.

Out of curiosity, he couldn't help asking Li Hong how he knew.

Li Shimin actually asked Li Hong about this.

Chapter 038 An incredible discovery, Li Hong exported it into a poem

"Look more, think more, practice more."

Li Hong answered habitually.

Not long ago when Li Shimin asked him how he knew, he answered the same way.

Anyway, it is impossible to tell them that they are time travelers, knowledge is learned from later generations.

Besides, it's useless to tell them, they don't even know what time travel really means.

"what?"

Du Ruhui immediately exclaimed.

His voice was a little loud, and his expression was a little exaggerated.

Du Shijing, who was sitting next to him and was listening to the conversation between the two with great interest, was taken aback.

But just one sentence?

Why is my father so shocked?
