Seeing the Eleventh Emperor Uncle, Li Ke naturally hurried forward to salute.

As a prince who has been "exiled", and has just been taught a lesson by the emperor, Li Ke is now much more mature than before. And knowing that this eleventh imperial uncle was quite valued by his father, Li Ke naturally did not dare to show the arrogance of his prince - even if it was now that the two met in private, he did not want to leave a bad impression on this imperial uncle.

As an "imperial uncle", Li Yuanjia naturally didn't put on any shows, and he was very amiable to help his nephew up.

In the final analysis, he is only Li Shimin's younger brother, and he is also a half-brother.

For an emperor, the younger brother is a creature...... Well, how to say it? It must be preferential, after all, there is a blood relationship, whether it is from the consideration of maintaining the rule of the royal family surnamed Li, or from the consideration of the world's leisurely people, Li Shimin cannot be too harsh.

What's more, he has a lot of sons of his own!

If Li Shimin dares to treat his younger brothers badly, his sons will definitely do the same, and in the end, his sons will definitely suffer!

But in any case, the younger brother is still not as close as the son after all.

So a few years ago, when Li Yuanheng and others met Li Tai, Li Ke and others, they not only had to salute, but also saluted their nephews first, because in the eyes of everyone, even if they are both princes, there is a huge gap in everyone's status!

But after Li Shimin realized this, everything changed.

Therefore, when he knew the history and understood that although the nephew in front of him was quite favored by Li Shimin, he would never be able to stand at the center of power in the future, it was naturally difficult for Li Yuanjia to have any special feelings.

It's just that a polite attitude is still necessary.

After some greetings, Li Yuanjia carefully observed the famous King Wu, and naturally cared about his nephew's life in Anzhou, and then asked about his body, political affairs, friends, etc., and the atmosphere was quite harmonious.

The kid in front of him is really handsome and extraordinary.

He is tall, at least half a head taller than Li Tai's kid, and although his body is a little fatter, it is already very normal in Li Yuanjia's eyes. After all, in recent years, women's pursuit of fruitful aesthetics has begun to rise, while men's "rich" aesthetics have always been there, which can be seen from Li Tai's figure - no one will ever think that guy is too fat, and there are even many people who think that it is enough momentum!

It's already good to be able to maintain a slightly chubby figure.

The most important thing is that the young man is handsome!

Especially when compared to what I looked like when I first saw myself in the mirror a few days ago...... Well, Li Yuanjia, who is absolutely objective in two lives, can be sure that this kid is still a little more handsome than himself.

Whether it is the aesthetic view of the Zhenguan period or the twenty-first century, it is the same result.

And this kind of handsomeness is not the kind of handsomeness of small fresh meat, because Li Ke does not have the so-called big eyes and pointed chin, but a dignified and upright Chinese face, both the lines and the eyebrows and eyes are very tough, which looks heroic and masculine!

So even from a man's point of view, Li Yuanjia felt that the imperial brother's sentence "Yingguo is like me" was not praising his son, but habitually boasting......

Just when Li Yuanjia secretly looked at his nephew, and even began to think of the tragic experience of this kid in the future, wondering whether to help him, Li Ke finally couldn't help but be curious, and asked, "Uncle Huang, what is that cement?" ”

"Cement? Why did you suddenly remember to ask this? ”

After a pause, Li Yuanjia asked with some surprise.

"Hehe, just curious."

Blinking, Li Ke said with a smile: "When I came in just now, I walked on the cement road, and I felt very surprised - this thing is hard and flat, if you can pave one from Chang'an to Anzhou, wouldn't it save more than half of the time back and forth?!" ”

Speaking of the journey back to Chang'an from Anzhou, Li Ke is also bitter!

This sin is truly great!

The road is long and takes too much time, not to mention, everyone has long been used to it these years, but the potholed official roads along the way, as well as the muddy road conditions when it rains, make Li Ke very painful - riding a horse is very cold, and the carriage is very bumpy!

And in order to be able to rush back to Chang'an as soon as possible, he suffered a lot along the way.

So as soon as he heard Han Lucheng say that there was no problem with this road even after it rained, Li Ke immediately thought of the bumps on the road, and naturally became very interested in this cement.

Simply saying his thoughts, Li Ke looked at the Eleventh Emperor Uncle very expectantly, waiting for the other party's answer.

And then......

"Haha, no, no, no!"

After hearing his words, Li Yuanjia immediately laughed, waved his hand again and again, and said, "Pave the road with cement?" Your idea is so unrealistic! In fact, I asked people to build this kind of thing just for a hobby, at most I just built a few roads at home to try, and I didn't think about taking them out to pave the way for the time being! ”

"Huh? Why? ”

After a pause, Li Ke's brows suddenly furrowed.

"It's simple, because it's too expensive!"

The corners of his mouth twitched, and the smile on Li Yuanjia's face became a little reluctant: "If you use cement to pave the road, it is more expensive than using stones, how do you think we can afford it?" ”

When I said this, I was really a little congested.

Truth!

If cement is so easy to manufacture on a large scale, and can even be used to pave the way in the Zhenguan era, will the future of New China still need to be so hard?

Think about it, how many cement roads were there in China at that time?

If it is really used to pave the way, the cost is definitely high enough to bankrupt the imperial court!

The Romans were born with good luck and were able to pick up a large amount of volcanic ash for nothing, but the Tang Dynasty did not have such good conditions, so they could only burn cement by themselves......

Just a burning word determines that there is no future industrial system, don't think about large-scale application of cement!

Therefore, what Li Yuanjia can do is to produce on a small scale, first, to satisfy his own wishes, and secondly, to build some special buildings.

As for taking it out and paving the official road or something, it's good to think about it, it's not realistic at all!

While sighing, Li Yuanjia told his nephew the specific reason, and as for the cement formula or something, he explained it without reservation!

Except for glass and mirrors, Li Yuanjia didn't think about keeping anything else secret.

It doesn't make sense.

Even a lot of things Li Yuanjia can't wait to spread out, at least he can improve the technical level of Datang, right? Especially for something like cement, who can afford it, Li Yuanjia is afraid that he will have to thank others!

For such a result, Li Ke was also speechless, and asked with a frown: "Uncle Huang, according to what you say, it is impossible for cement to be used on a large scale?" ”

"This ...... It's not impossible. ”

After thinking for a while, Li Yuanjia's eyes flickered: "If there are a large number of people...... Ahem, I mean you don't have to pay for it, and you have a lot of people who can work all year round, I think you can still use this thing......"
