Jingwen took out a jar of tea leaves, and then asked the maids in the palace to make tea. After that, it was handed to Emperor Li Shimin and the servant Zhang Wansui next to him, and they also drank two sips of tea and immediately said that it was good.

"This thing is good, it smells pleasant, it's very good!" Zhang Wanzai said.

"Boy Jingwen, we're talking about Ma Zheng, how did you come up with this thing? Something is not right, right? Let's talk about Ma Zheng as much as possible, don't fool me with these unreliable things. Li Shimin said.

Jingwen said: "Your Majesty, if you want to talk about Ma Zheng, you must first talk about this tea, how do you look at the root of this tea?" ”

"Very good, much better than that kind of boiled tea. But what does this have to do with Ma Zheng? Li Shimin asked.

Jingwen was curious when he saw Li Shimin, and Jingwen immediately explained that he had seen a few Hu people in his teahouse today, and told Li Shimin about their cattle drinking tea. After that, he told Li Shimin what he had told about eavesdropping on those Turks, and Li Shimin's face immediately changed.

After that, Jingwen explained the eating habits of the ethnic minorities in the border areas, and explained that if those ethnic minorities did not have tea, they would be prone to diseases. This is enough to show that tea will be indispensable for those border ethnic minorities in the future, just like the salt of the Han people. Since it is indispensable, it can be used as an important method for the Han people to control the ethnic minorities in the border areas. Because it was almost impossible for the Turks, Tibetans and the like to produce tea, they could only buy it from the Han Chinese.

At this time, the Han dynasty could exchange tea for war horses. What's more, the place where tea is planted is a hilly or other place, which does not occupy farmland, and the cost is acceptable. What's more important is that this kind of tea will not allow the enemy to increase the strength of weapons, nor will it cause their own financial strain, and the main thing is that those Hu people like it, so many benefits are obvious.

"Is this true?" Li Shimin asked excitedly.

"Your Majesty, it's definitely true, it's more true than pearls. Your Majesty, I risked offending my international friends to eavesdrop, of course it's true. Jingwen said.

Li Shimin paced back and forth, and then said, "Call Fang Xuanling and Du Ruhui!" ”

Soon, Fang Xuanling and Du Ruhui also came, and after listening to the emperor's explanation, they actually knew that this tea would be such an important thing for the Hu people. They're not fools, and they're strategists before, so they're better at this kind of conspiracy. Of course, they knew that if they had mastered some of the necessities of controlling those Hu people, then they would probably have to compromise a lot with the Han people. Even, they are going to trade war horses.

The reason why the Central Plains Dynasty was weak to the Hu people was because the Central Plains Dynasty did not have many cavalry. The cavalry is mainly war horses, and the Han people are difficult to have a large number of war horses armed cavalry. The Hu people were also shrewd, and they knew that if the Han people were given a large number of war horses, the Han people would also have the advantage of cavalry. Therefore, it is also very strict about the control of war horses.

Now that the Han people have tea, they can take the opportunity to ask them to trade war horses, which is much better. And the Hu people are in urgent need of tea. However, the Han people can slowly breed war horses by themselves, which is not very urgent. And those Hu people also had no other materials that the Han people urgently needed, so the Han people only needed war horses and nothing else. The Nahu people were at a disadvantage in trade, and they could only exchange a large number of war horses for these teas.

"Your Majesty, I think this thing is feasible! Since the Turks are obsessed with our tea, we can take the opportunity to ask for war horses. As long as we have a large number of cavalry in the future, where will we be afraid of them Turks? Now we are like this, and that is because we lack cavalry. Once the Turks attacked, even if they lost, they could quickly retreat, and our infantry could not catch up. And if we have cavalry, we can pursue. In this way, we can also have an advantage. Fang Xuanling said.

And Du Ruhui also added: "Your Majesty, not to mention that our Central Plains have as much as we want for war horses." We can't do without war horses in the Central Plains, and if there are no war horses, then our Central Plains will be in danger. Therefore, we need a lot of money to buy war horses, and tea is the best choice. As long as the tea is sufficient, don't worry about the Turks not taking the bait! ”

Fang Xuanling and Du Ruhui both elaborated on the situation that they could take the opportunity to blackmail the Turks, but Fang Xuanling and Du Ruhui came out of the troubled times, but there was no politeness, righteousness and shame. These two guys are definitely not good birds, they will not give tea to others for the sake of face. These guys attach great importance to practical interests, but they don't pay attention to false fame.

And Jingwen, a petty official, also interjected and said: "Your Majesty, we can make those Turkic people addicted to tea in the future, and we can take the opportunity to control the export volume of tea." If the Turks behave badly, we can control the export of tea, or even stop the tea and horse trade with the Turks. Anyway, we don't have to buy war horses from the Turks, we can buy them from Tibet! We can't hang ourselves from a tree, and we have to find ways to buy war horses. Anyway, if the Turks have anything unfavorable to us, we can stop the tea and horse trade and sanction them. ”

"Good! That's a good idea! Li Shimin also said.

Jingwen actually instilled in everyone the method of trade sanctions in later generations, that is, to use their dominant position in trade, and then sanction those countries that are disrespectful to themselves. Of course, this is based on the fact that you are able to protect yourself. After all, the trade war is only a supplement to the armed war, and if the national defense strength is not good, then the enemy will not come to trade directly, but will come directly to loot.

Now, Datang is qualified to sanction the Turks with trade. The reason why the Turks were able to come to the Weishui Alliance last year was because Li Shimin had just ascended the throne and had not yet secured the throne! At that time, the world had not really recognized Li Shimin as the emperor, so the Turks came to take advantage of the fire to rob, which allowed the Turks to extort all the money from the treasury. Now that Li Shimin is firmly on the throne and has deployed a large army on the border with the Turks, he is not afraid of repeating the mistakes of last year.

In such a situation of strong national defense strength, Datang has the capital to impose trade sanctions on the Turks without fear of invasion by the Turks. What's more, the Turks were also unstable internally, so the Turks had no way to launch another large-scale attack on the Tang Dynasty.
