After pondering for a while, Li Su couldn't help but say: "If you plant trees on the edge of the desert, it is naturally the poplar tree that is the easiest to survive. ”

Hearing this, the envoys of various countries couldn't help but exchange a look, and they all saw shock in each other's eyes.

It turned out that this King of Shu was not untargeted.

He, a prince of the Central Plains, how could he know about poplar in the desert?

It seems that this King of Shu is really omniscient of the three religions and nine streams, and all the sons of a hundred schools know everything!

At the end of the end, there is a talent who has been through the heavens and latitudes!

Li Su continued: "When planting, it was not easy to survive because of the drought. If you want to increase your survival rate, you can do this. Prepare a jar and fill it with water. Then, when planting the tree, put some of the roots in the jar, seal the jar, and bury it. ”

In this way, the water in this jar can be preserved for at least a month or two. With this buffer time, the planted trees will basically be able to survive! When you get back, you can give it a try. ”

After listening to Li Su's method, the envoy of the small country couldn't help but light up suddenly.

I have to say that this method, just after listening to it, will feel feasible.

With this approach, they will be able to curb desertification outside their country.

Their land will not be swallowed up by the desert every year.

And not only the envoys of that small country, but also the envoys of other countries, even Li Shimin and those ministers.

After hearing this method, they all showed thoughtful expressions.

This method is definitely a simple and effective method.

It's so simple that you just need to hear about this method and you can easily implement it.

But with such a simple and effective solution, why hasn't anyone been able to come up with it for so many years?

And what about the king of Shu? I came up with it casually, this is the gap!

Well, well, in fact, this method was gradually explored by later generations in the process of desertification control and afforestation.

The envoy of the small country couldn't help but look at Li Su deeply, and said sincerely: "On behalf of all the people in our country, I would like to thank His Royal Highness the King of Shu of the Tang Dynasty for his guidance. ”

Li Su smiled and said: "Everyone is responsible for governing the desert, so there is no need to be grateful." ”

The envoy of the small country then asked, "Your Royal Highness the King of Shu of the Great Tang Dynasty, do you know how to grow crops in the desert?" ”

This question is the most important thing!

They really hope that the King of Shu can solve this problem in a simple and effective way, just like he solved the problem of planting trees on the edge of the desert just now.

In this way, they will benefit a lot from each country, and even say that they can change their fate.

Li Su smiled and said: "Of course there is a way, the soil of the grassland is not suitable for the growth of most plants. But potatoes can still grow, and the harvest of potatoes is still good, one acre of land can produce at least two thousand catties or more, and it can also be used as a staple food. ”

Hearing Li Su's answer, the envoy of the small country couldn't help but be surprised and happy, and couldn't help asking: "Your Royal Highness the King of Shu of the Tang Dynasty, I don't know what kind of crop this potato is?" What does it taste like? ”

Li Su smiled and said, "Yesterday you were in the food city, did you eat sour and hot shredded potatoes?" ”

The envoy of the small country nodded again and again and said: "I have eaten it, it is very delicious, it is a rare delicacy in my life." ”

Li Su smiled and said: "The potatoes I am talking about are the raw materials for burning hot and sour shredded potatoes. ”

The envoy of the small country couldn't help but ask in surprise: "Your Royal Highness the King of Shu of the Great Tang Dynasty, is this true?" ”

Li Yu laughed and said: "Naturally, it's true!" ”

The envoy of the small country asked with apprehension: "Your Royal Highness the King of Shu of the Tang Dynasty, can you sell us some of these potatoes?" In terms of price, you can rest assured, we will definitely pay a high price! ”

Li Su pondered for a moment and said, "This question, hahaha! Let's talk about it later, let's talk about it later! Let's talk about your problem first, did this king give a perfect answer? ”

The envoy of the small country nodded again and again and said: "Your Royal Highness the King of Shu of the Tang Dynasty, your profound knowledge is the only one I have ever seen in my life. His admiration for His Royal Highness is like a surging river! ”

……

At this time, the Tuyuhun envoy stood up.

"Your Royal Highness the King of Shu, we want to see the majesty of the Tang army, I don't know if we can?"

Hearing the words of this envoy, Li Su couldn't help but nod slightly.

In fact, even if Tuyuhun's envoy didn't mention this request, Li Su would inevitably use the excuse to show the military strength of the Tang Dynasty.

It's not enough to overwhelm them on the subject.

It is necessary to give them enough deterrence in terms of force, so that they can feel frightened and dare not act rashly.

And the envoy of Tuyuhun did not ask any difficult questions, but raised them with great interest.

Sure enough, it's very good.

Thinking of this, Li Su couldn't help but smile and said, "Okay, since you all want to see it, then let you see the standing strength of the Yizhou Nineteen Horsemen!" ”

Yizhou Eighteen Rides?

Hearing this name, they couldn't help but think of Yanyun's eighteen horses.

Yanyun Eighteen Rides, according to legend, was founded by Luo Yi.

At that time, people often described him: fast as the wind, as fierce as fire, wherever he went, there was not a single grass left. Strong bow scimitar, good at riding and shooting, with one enemy hundred, never tasted defeat.

Yanyun Eighteen Cavalry took the horn as an order and only obeyed the orders of its master Luo Yi. The Yanyun Eighteen Cavalry is a very terrifying killer force, and every time the Yanyun Eighteen Cavalry appears, it will bring a terrible massacre.

And the current Yizhou Eighteen Horsemen were created by following the example of Yanyun's Eighteen Horsemen?

Just when everyone was puzzled, Li Su walked forward directly with the envoys of various countries.

Ladies and gentlemen, the terrain here is narrow, and it is inconvenient to display, so please come with this king.

In a short time they came to an open field with a forest in front of them.

Then Li Su gave an order, and suddenly there was a sound of horses' hooves from a distance.

Immediately after, in everyone's sight, were eighteen handsome white horses.

Each horse is strong, and the hooves are shining gold, and they are like horseshoes made of gold.

A knight on horseback, all dressed in white suits, with a white cape, and a silver moon scimitar worn at his waist.

These eighteen horsemen are like growing on war horses, and the men and horses are one.

Eighteen horsemen staggered forward, intricately intricate, dazzling to see, and they couldn't see their formation at all.

They were like a whirlwind, and they were extremely fast.

When they reached a hundred paces away from the woods, they suddenly pulled their horses together, and the horses suddenly stood together, their front hooves raised high, and they roared to the sky.

The eighteen horses actually stopped at the same time, which was neat and frightening.

Next, the eighteen horsemen simultaneously removed their longbows and bent their bows to shoot arrows together, aiming directly at the grove in front of them.
