Every time like this, Li Yuanjia will be full of energy.

He changed history...... In other words, it can also be the determination to be a "great man" of history, and now it is becoming stronger and stronger.

Every time the age of this life increases, this idea becomes stronger.

At the beginning, in fact, Li Yuanjia didn't have this mind at all, because of his special identity and special historical environment, he had to be careful and live honestly. In his spare time, Li Yuanjia thinks most about how to make his life more comfortable and less boring.

As for the rest, he had no idea.

Because Li Yuanjia knew from the beginning that it was impossible for him to show his strength in the political, military, and even economic fields in this life, and it could even be said that the greater the influence, the faster he would die! Even if the second Li Shimin doesn't deal with him, I'm afraid that the gang of eldest grandson Wuji will not let him go.

This kind of thing has happened in history.

For example, the eldest nephew Li Ke, who do you say he offended? Li Yuanjia has seen it a few times, and he feels that kid does have more ideas...... It's not terrible for a young person to have ideas, but it's terrible to be in this era, and to have such a special identity, it's terrible to have ideas.

Therefore, Li Yuanjia has always warned himself not to think too much, let alone cross the line at will.

But......

Fortunately, even if Li Yuanjia's identity as a prince is shackled, the times still leave him a window after all...... No, in his opinion, there should be a door left!

A door to science!

Although everyone looks down on those obscene skills these days, and even the mathematical artifact of Arabic numerals is difficult to promote because of the pride of the Central Plains scholars, Li Yuanjia is willing to persevere.

And, crucially, he can stick to it too.

Although the prince of the Tang Dynasty and the emperor's younger brother are not "appropriate" to get these strange and obscene skills, especially Tianzhu numbers, Song characters or something, and they have been ridiculed by Li Shimin many times, and a few times Li Yuanjia even felt that the emperor had the intention of beating himself, but there is no doubt that he felt that the shackles on his body were slowly beginning to be loosened.

Because of the curved plow, but also because of the overturning and improved papermaking.

Maybe it's because he thinks that the things that his younger brother has made are "still a little useful", although he still feels that the prince always tosses these things out of order, but the emperor's attitude has unconsciously changed a lot, and even in Li Yuanjia's opinion, it has been a bit of a tacit acquiescence. 、

This is very obvious in the salt, tea, and of course, Huang Ren and Ma Yuan.

So this is also the reason why Li Yuanjia dared to come outside the city frequently in July and mingle with the craftsmen of those workshops every day - on the one hand, the acquiescence of the emperor, which is the most important factor; On the other hand, it is also because Li Yuanjia is slowly thinking about it now, maybe focusing on "strange and obscene skills" will cause the emperor's dissatisfaction and reprimand, but if you think about it differently, isn't this the best disguise for yourself, or a cover?

Think about it, who would worry about a prince who thinks about making glass and paper every day?

Otherwise, with the things that Li Yuanjia made before, if it is really unacceptable, let alone the emperor, I am afraid that my uncle Yu Wenshi and his father-in-law Fang Xuanling would have jumped out and tried their best to persuade themselves, right?

"Hehe......"

"Step on ...... Trample...... Step ......"

Just when Li Yuanjia shook the recliner and couldn't help laughing twice, he only heard a rush of footsteps coming from a distance, and quickly approached the place where Li Yuanjia was.

Without looking at it at all, Li Yuanjia already knew the identity of the person who came: "Han Lucheng, why are you in such a hurry?" ”

"Big, king, letter from Jiucheng Palace!"

Without waiting for his breath to even, Han Lucheng hurriedly stepped forward to salute, and then held a letter in both hands and presented it to Li Yuanjia.

"Huh? Letters again? ”

Squinting his eyes, Li Yuanjia raised his hand a little carelessly and took the letter in Han Lucheng's hand.

In the summer of the thirteenth year of Zhenguan, the center of the Tang Dynasty was still in Jiucheng Palace.

As the king of Han in the Tang Dynasty, although Li Yuanjia does not need to go to Jiucheng Palace with the holy driver to escape the summer, it is still very necessary to send people to Jiucheng Palace to guard it, and receive three letters every month to understand what happened in the Tang Dynasty and the decisions of the court.

Anyway, he is also the Yongzhou pastor of the Tang Dynasty!

Anyway, Li Yuanjia didn't hide it, he put it in front of everyone generously, and he was never afraid that others would know. And to tell the truth, Li Yuanjia is generally not interested in the news from these Jiucheng Palaces, because most of the time it is the news that the bandits in which state have rebelled again, or how many people have died in which state because of the drought.

So even if he took over this "report", Li Yuanjia was actually excited.

There was no good news this summer, and he really didn't want to watch it.

However, since he had already received it, and it seemed that there was still a little time before eating, Li Yuanjia no longer hesitated and directly opened the letter in his hand.

After reading the first page, my face was full of "sure enough" expressions.

The people of Zhenguan for thirteen years are really miserable, and the drought has continued until now, even if the center of the Tang Dynasty has sent officials to relieve the disaster, it is still difficult to change the fate of many people. At least in terms of Datang's current national strength, don't think that it would be good to let everyone survive this year in peace and ensure that most of the affected people survive.

So after shaking his head, Li Yuanjia quickly skipped this part.

The next content is much more relaxed, and there are a few more important ones, one is that there are two more states that have rebels, and the name seems to be from the southwest...... is accustomed to it, and it can't make Li Yuanjia feel strange; The other is the birth of a new Prince of the Tang Dynasty, and the identity of the other party is Li Yuanjia's younger brother, that is, Li Yuanying, the twenty-second son of Tang Gaozu......

Seeing the name Li Yuanying, Li Yuanjia's face was full of complexity.

This kid, is he nine or ten years old now?

A little big kid was directly sent to Tengzhou, Shandong by the emperor and was named King Teng...... If it weren't for the fact that he had memorized the "Preface to the Pavilion of King Teng" in his previous life and firmly remembered the name of King Teng, I am afraid that Li Yuanjia would have been at a loss for a long time!

But now, he knows a lot about this brother.

Li Yuanying's reputation in history is not very good, he has built pavilions and pavilions in several fiefdoms, and bullied men and women, so that his nephew Li Zhi is helpless. But in the next Wu Zetian era, so many Tang royal families were killed, Li Yuanying not only survived, but even received many rewards from Wu Zetian......

Li Yuanjia sometimes has to wonder if it was because he was a bastard, so Wu Zetian let him go?

Keeping him is to discredit the royal family surnamed Li?

"Hehe, who knows."

Thinking about it, Li Yuanjia suddenly smiled, shook his head, and left this brother behind. In any case, this kid has nothing to do with him, and there should be no contact in the future, after all, almost all the princes don't get along with each other, this is the reality of Datang.

Blinking, Li Yuanjia continued to look back, and then quickly stared, and then sat up from the recliner with a rub: "Hou Hongren? Who is this man...... Hey, whoever he is! The point is that this guy opened the road to Jiaozhou and Guizhou? This...... Is this to Vietnam? ”
