After listening to Li Mengwei's words, Xiao Er's face changed.

"Guest officer, you're laughing, how did you drive the inn to the vicinity of the embankment?"

"Isn't that waiting to lose money? It is washed out once a year, and the water floods it, and even if the inn is not washed away, most of the objects in the inn are soaked. ”

"The silver we have earned hard for a year may not be enough to lose!"

Li Mengwei smiled and shook his head: "That was in previous years, and this year will not be like this." ”

Xiao Er didn't believe it.

"My lord, you may be from a foreign enemy, and you don't know anything about the situation in our Huainan."

"It's just that muddy embankment, if it can hold back the water, there is a ghost!"

"We didn't count on it!"

"All we want is for the water to come later, so that the big guys can clean up the grain and grass in the field."

"This way, the price of food will not rise too much."

In fact, although the little guy is just the second child of the inn. _o_m

But he also hated this great water to the extreme.

Once the flood comes, Huainan will inevitably suffer.

At that time, there will be no merchants coming to Huainan at all.

The inn's business will also plummet.

In this case, who wants to live in Huainan?

Li Meng tasted what he said, but he promised:

"Not this year, I said that the levee will not collapse, it will not collapse!"

Xiao Er only thinks that the other party is drinking too much and talking nonsense.

So he laughed and said: "Yes, yes, what the guest officer said is yes!" The levee won't collapse! ”

Li Mengwei knew that the other party was perfunctory, and he didn't care.

After all, even if this kind of thing is said a thousand times now, the little guy may not believe it.

When the flood came, and when he saw the facts, he had to believe it even if he didn't believe it.

"Alright, go and prepare something for us!"

"Yes, guest officer!"

Li Mengwei sent Xiao Er, and then took Cao Menghua into the room to discuss the important matter of flood fighting.

The reason why he only stayed for one night was simple.

Huainan officials must stay on the front line of flood fighting, and so does Li Mengwei.

What would it be like to let those people stay by the levee and watch over the floods, while they themselves were happy in the inns of the city?

In the past, when he was fighting, Li Mengyan was used to taking the lead.

Even though Li Shimin talked to him many times about this, he still couldn't change it.

So this time is no exception.

Li Mengwei still planned to personally guard a section of the embankment.

The embankment is in, and the people are there!

The carriage was bumpy all the way.

Qin Fan finally prepared the potion promised Li Shimin before rushing to the East China Sea.

These potions are not for human consumption, but are specially formulated for locusts.

Since the first departure, it has been a drought.

Now that it has come to the coast of the East China Sea, it has not improved.

Occasionally, a few drops of rain fall from the sky.

But there is no difference between such sporadic raindrops falling and not falling.

Now that the drought is a foregone conclusion, locust plagues are bound to follow.

Therefore, it is necessary to prepare immediately to fight locusts.

Qin Fan Zeng also proposed many methods.

For example, rice and wheat are replanted with potatoes and sweet potatoes with rhizomes in the ground.

In this way, the locusts will eat only the stems and leaves of the crop on the surface, while the stems buried in the ground are intact.

There will not be much loss of food.

However, on the one hand, there is a limited amount of grain, and on the other hand, it is impossible for the people to uproot the grain that they have worked so hard to grow and irrigate.

Therefore, this method can only be put on hold for the time being for next year.

As for biological control, in the face of the overwhelming number of locusts, biological control may only have little effect.

In an ordinary year, raising chickens and ducks and other poultry can also have a lesstening effect on locust plagues.

But this year is different, and with such a severe drought, the locusts must have multiplied well.

If you want chickens and ducks to eat the locusts, I'm afraid it's a little unrealistic.

So, Qin Fancai.

I prepared these potions.

Along the way, he blended a number of varieties and tested them at the same time.

The material on hand is simple, the effect is extraordinary, and it is also suitable for a wide range of use.

It is the final product developed by Qin Fan.

He handed the potion to Li Shimin together with a piece of paper with the recipe and recipe, and said:

"Fortunately, this medicine can be regarded as a concoction."

Hearing this, Li Shimin was overjoyed:

"I'm going to order people to send copies to all places, and make sure that every place is equipped with such locust killing weapons."

Qin Fan nodded, and then admonished: "Although this elixir is mainly aimed at locusts, the toxicity in it is only a trace amount. ”

"If the people come into contact with it, it doesn't matter."

"But after all, it is a pesticide, and the people need to be informed that after spraying, crops cannot be picked for consumption for at least three to five days."

Li Shimin nodded: "Remember." ”

Then, a knight lined up from the ranks and began to rush to various places with potions and copied formulas.

At this time, it is a race against the locust plague.

If you can wait for the potion recipe to arrive before the locust infestation is raging, and make a large number of blends.

Then the locusts are not to be feared.

But if it's too late, and the locusts are already raging and gone, it's too late to say anything.

Letting go of a major event in his heart, Li Shimin breathed a sigh of relief.

Nowadays, you can feel the salty sea breeze blowing from the sea.

It is only half a day's journey from the coast of the East China Sea.

It may not be long before the silhouette of the huge merchant ship can be seen.

In this regard, Li Shimin has expectations.

After all, as long as a merchant ship makes a round trip between Datang and those countries in Europe, it is dozens of times the profit.

In this way, not only does the imperial court not have to worry about the silver, but even the national bonds that it borrowed from the wealthy families can be repaid smoothly with interest.

Construction of the Huainan dam can also begin.

Datang's mining and smelting can also be popular.

It is a cement road, which can be extended from Wannian County, spread to Chang'an City, and then spread throughout the entire Tang Dynasty.

More than 800 years ago, King Yingzheng of Qin implemented the same track and the same text.

But the roads of Daqin are still muddy.

Even if it is an official road, it will become difficult to move an inch after a heavy rain.

If you pave a concrete road, everything will be different.

No matter how heavy the rain is, the road is still refreshing.

The groom didn't have to worry about cleaning the carriage either.

And the cement road is only Qin Fan's most elementary plan.

Since then, asphalt roads, various tracks.

will gradually emerge with the development of Datang's national strength.

Qin Fan also hesitated about whether to bring these things to the people of the Tang Dynasty.

After all, these are not the objects of this historical era. @

By doing so, you are undoubtedly forcibly speeding up the course of history.

But soon, Qin Fan was relieved.

Even if it speeds up the course of history, so what?

At least the people will be able to profit from it and live a better life, right?
