With a few math books with him, Li Tai left the Han Palace.

And Li Yuanjia was full of doubts, and pondered Li Tai's intention for a long time - he really couldn't believe that the other party was for a few books, so after thinking about it, there was only one answer, that is, he went to see the emperor and the prince successively, which made Li Tai pay attention......

"Could it be that this kid has that mind now?"

Thinking of a possibility, Li Yuanjia naturally shuddered and quickly shook his head.

Can't think about it too much!

And whether this is the case or not, he, the king of Han, must not be involved in the battle between the two brothers, at least not yet!

The current Li Yuanjia is a complete idle king.

Perhaps because of things such as the plough, the overturned, and even the white paper, the emperor looked at his younger brother differently, and even gave him a false title of Yongzhou pastor and the right to stay in Chang'an. But Li Yuanjia himself knows his identity and situation very well, he is still just an idle king.

And after experiencing all the things before, Li Yuanjia also discovered one thing, that is, the future things in his head...... Or the things that have been taken out are not necessarily so important in the emperor's heart.

Tables and chairs that are more comfortable than a few are nothing more than making people sit more comfortably.

Stir-frying, iron pot and thirteen spices, because of the high price of oil, pig iron and spices, are only things that only a very few people can enjoy.

Better white paper and innovative movable type printing, before the technology was completely matured and the prices of paper and books fell sharply, were at most novelty in Li Shimin's eyes, and did not play a decisive role.

There are also things like cotton and glass, and even in Li Yuanjia's eyes, they are also to make some preparations for the future, for this era...... At least during the Zhenguan years, you really can't see the possibility that they can attract everyone's attention!

Therefore, the only thing that can make Li Shimin pay attention to it should be the curved plough and the improved overturn.

The former allowed the peasants to cultivate more land, and the latter took advantage of the drought in the 26 states to let the emperor see its potential value.

As for Li Yuanjia's Songti characters and fried tea......

He didn't even want to mention it, it was all tears!

Song style is now called Han Wangti by many people, but Li Yuanjia knows that it is definitely not a compliment, but a faint taste of ridicule - this is the future of printing, but who does not despise anyone with a little calligraphy level? As for roasted tea, no one despises it, but thinking about Li Tai's attitude just now, Li Yuanjia can only say that it is not easy to make Tang people fall in love with it!

Just as it is not easy to make people who are accustomed to drinking coffee fall in love with tea in the future, or people who are accustomed to tea to fall in love with coffee, it is estimated that it is necessary to slowly cultivate a group of "elegant people" to make people who are accustomed to goat milk and cheese fall in love with tea......

……

Just when Li Yuanjia was thinking about his eldest nephew and second nephew, worried that he would be involved in the battle between the two imperial heirs, on the carriage back, Li Tai was also thinking about his eleventh uncle.

In his eyes, Li Yuanjia is really a wonderful person.

In Li Tai's memory, this uncle actually had no sense of existence before, and even after Li Yuanjia was sent to Luzhou to be the king, he couldn't remember this uncle. But two years later, Quyuan Plough, which was sent from Luzhou to Chang'an, suddenly reminded countless people of Li Yuanjia, the prince of the Tang Dynasty.

For Datang, Quyuan plough is too important.

Before and after the Quyuan plough was sent, iron pots and stir-fried vegetables became popular in the homes of the powerful, and the appearance of thirteen incense and tables and chairs also made more and more people remember the figure of Li Yuanjia, the king of Yu.

However, what surprised Li Tai the most was that King Yu migrated to the king of Han and received the position of Yongzhou pastor!

You know, he's a prince.

According to the rules of the Tang Dynasty, the prince is an adult...... No, it should be said that most of the princes were basically sent out before the crown salute, and apart from Li Tai himself, he really didn't see anyone who could stay in Chang'an.

So from that time on, Li Tai began to pay attention to this eleventh uncle.

After all, it seems that King Han is very favored by His Majesty, and he is also the son-in-law of Xuanling of Liang Guogongfang, if it weren't for the identity of the prince, Li Yuanjia's center in the Tang Dynasty would probably be a different scene.

But slowly, Li Tai soon ignored this eleventh uncle again.

Because Li Yuanjia, who returned to Chang'an, became an otaku again - it is said that in order to keep filial piety for the first emperor and Yuwen Zhaoyi, King Han almost closed his door, and he was not even willing to move in the mansion given by the emperor, but lived in a "small" house.

For a time, the reputation of Han Wang Chunxiao spread all over Chang'an.

Li Tai naturally scoffed at this, thinking that this uncle might really have a bad brain. After all, everyone is not those rotten Confucians, and they often mourn for a while, who is really so serious about keeping filial piety for three years?

And I heard that Li Yuanjia built many workshops outside the city, making white paper and glass, which made Li Tai despise him more and more. The princes are not in business in private, but everyone is sneaking here, so they have to find a few people to cover it up in the open, who is as blatant as King Han who is building a workshop on his own land outside Chang'an City, isn't it clear that he is telling others that I want to do business?

And when the news came that Han Wangfu had bought a set of shops in Dongshi, Li Tai was speechless.

It's just that when I thought that this imperial uncle was incorrigible, the news suddenly came that King Han was summoned by His Majesty before the wedding, and after the wedding, he was summoned by the crown prince. After Li Tai got a deck of "pirated" playing cards, he was also amazed by this fresh game, and finally couldn't help but send a letter of worship to Li Yuanjia......

Today's trip to King Han's Mansion really surprised Li Tai.

At least in his heart, he really didn't have no interest in the bamboo forest, the pavilion, and the kung fu tea, especially the elegant action of making tea in the ink painting, and every step full of meaning, which made Li Tai's heart move.

It's just that in order to protect his face as King Wei, he didn't show it on the spot.

So......

For this eleventh uncle, Li Tai suddenly became interested again.

This time, he saw several new things: cards, kung fu tea, a new type of rollover that was similar to the quyuan plow, and of course, the so-called magic method that would make the carpenters several times faster!

"What's the mystery in these books?"

After squinting his eyes and thinking for a while, Li Tai couldn't help the curiosity in his heart, picked up the "Tianzhu Numbers" marked with the words of the first volume, and flipped through it casually......
