Sending someone to Luzhou, of course Li Yuanjia would not let people bring only two books over.

Anyway, Li Lingkui is also his own brother, born to a mother, and it can be said that he is the closest person left in his life, so when people set off from Han Wangfu the next day, there were a total of six people and three carriages, and the things they brought could weigh hundreds of catties!

In addition to books, there are also some small things that Li Yuanjia has recently designed.

It's not anything particularly valuable, it's just something he specially designed to make it more comfortable to live in the new Han Wangfu.

Of course, it's all ideas from the future, the kind that if you make a large number of them and sell them, you can make thousands of dollars casually.

It's just that Li Yuanjia has long given up thinking about making money from small inventions.

In this era, there should be no problem for ordinary people to do this, and it seems that the little nobles can do it if they give up their faces, but he is a dignified prince of the Tang Dynasty, with 700 households and tens of thousands of acres of professional fields......

The impeachment of the officials is a small matter, but it is a big deal to be cleaned up by Li Shimin!

So in addition to using these things at home, Li Yuanjia also plans to send a set to his younger brother first, and after the emperor and they all return to Chang'an, he will send a set to Li Shimin, Fang Xuanling, and his uncle Yu Wenshi and that side. As for whether there are any people who think it is easy to use and imitate something, Li Yuanjia doesn't care.

Anyway, the detailed drawings or something, he had already entered them into his study, and he was going to throw them out sooner or later......

"This prince is so unaccomplished!"

After getting the news from Han Shan that the convoy had set off, Li Yuanjia couldn't help but sigh secretly in his heart. In fact, he really wanted to experience the thrill of making money in Datang, but he ......

"Step! Trample! Step ......"

Just when Han Shan watched the king's face flicker, and he couldn't understand it, he suddenly heard a rush of footsteps in the corridor outside.

With a frown, Han Shan glanced at Li Yuanjia again.

Seeing that the king was still squinting and contemplative, as if he didn't seem to be aware of it, Han Shan quietly retreated to the door of the study, pushed open the door and went out and asked in a low voice, "What's the matter?" ”

The little guy who was already standing outside the door with low eyebrows hurriedly saluted, and said respectfully: "Steward Han, the person we sent to Qiantang is back." ”

"Oh?"

After listening to Xiao Xiao's reply, Han Shan's eyes suddenly lit up, and he hurriedly asked in a low voice, "You're back?" How many carriages? ”

"Two carriages!"

"Good!"

Han Shan was suddenly overjoyed and nodded heavily.

Qiantang was formerly known as Qiantang, which was the seat of Hangzhou, belonging to Jiangnan Province, and was renamed Qiantang in the fourth year of Wude because of the avoidance of the Tang Dynasty. This place is thousands of miles away from Chang'an, and it is not close to Luzhou, so it has nothing to do with Han Wangfu, but because of Li Yuanjia's sudden order a few years ago, Han Shan had to send a few people to this place, and every year he has to collect something from there and bring it back......

"You are waiting here, and I will go and tell the king at once!"

Han Shan waved his hand to let the little guy wait, and he hurriedly walked back to the study, and said in a low voice: "King, the person we sent to Qiantang has returned." ”

“…… Well? ”

Raising his head a little dazedly, Li Yuanjia hadn't come back to his senses from his thoughts: "Qiantang? ”

"Yes, King!"

Nodding, Han Shan hurriedly said, "It's the tea you asked us to collect...... They are back from Qiantang! And brought back two whole carts of tea! ”

"Oh? So much? ”

Li Yuanjia, who finally came back to his senses, suddenly lit up, and asked in surprise: "Is it the tea that has been fried?" Or ......"

"Back to the king, it's fried!"

"Haha, good!"

After listening to Han Shan's words, Li Yuanjia patted the armrest of the chair and stood up with a smile.

In order to drink a good cup of tea, he sent people to Hangzhou every year to buy tea. In the past few years, because it was not very ripe, and the number of tea leaves in Hangzhou was not very large, the number of tea recovered each time was relatively small, and the most one was only more than 40 catties.

I didn't expect to be able to receive two wagons of tea this time!

And because this year, someone was specially sent to rent a set of yards and ship the collected tea leaves back after roasting, so the tea leaves in these two carriages were still dry......

"Now, no matter how much you toss, it's enough!"

After secretly thinking about it, Li Yuanjia hurriedly said: "Han Shan, order someone to bring twenty catties of tea, catch up with the convoy in Luzhou, and send the tea to King Yu!" ”

"Yes, King!"

After listening to Li Yuanjia's order, Han Shan was not surprised, and immediately nodded.

And when Han Shan went out to convey the order and went to get some new tea by the way, Li Yuanjia walked around the room a few times with some excitement, and then walked back to his desk, spread out the paper and wrote a big word "tea" on it!

He is not very clear whether the tea collected from Hangzhou is the future Longjing tea, but there is one thing Li Yuanjia is very sure of, that is, if he can popularize the technology of roasted tea in Datang in advance, then tea, an important strategic material, is likely to appear on the stage of Chinese history in advance!

The most important role of tea is not to pretend to be forced.

In the northwest and southwest regions of the Central Plains, due to the influence of the natural environment, meat is basically the main food, and the drink is also cheese. The result of this is that although the body will be stronger, but there is a lack of essential vitamins - drinking tea can reduce the greasy caused by eating meat for a long time, and on the other hand, it can supplement vitamins, which can be said to be extremely important for many ethnic groups.

It was only later that everyone understood this, so tea became an important strategic material!

Even after the Tang and Song dynasties, the salt tea monopoly will replace the salt and iron official camp. The Central Plains Dynasty monopolized the production of tea, and exchanged horses with the ethnic minorities in the northwest through the tea and horse trade, so in a sense, it was through tea that it mastered the trade lifeline of the edge of China!

In the Ming Dynasty, the imperial court would even set up a "tea division" in the tea-producing area, stipulating that the tea monopoly, and the merchants who sold tea must have a "tea introduction" or "tea by", and stipulated that "those who leave the country with private tea will be beheaded"! All "side tea" imported abroad is uniformly operated by the "Tea and Horse Division" and is regarded as "official tea".

To put it simply, this is the origin of "treating the border with tea".

Li Yuanjia naturally didn't understand how to operate it specifically, but he understood that Datang definitely hadn't understood the importance of tea yet! Because in the north of the Tang Dynasty, that is, the center of the rule, there are even few people who drink tea, and everyone still prefers cheese, which is the same as those people in the borderlands......

"Whether tea can be made a strategic material in advance depends on the operation of this king in the next few decades......"
