"Huh? King Wu? ”

After following the gaze of the eldest grandson Wuji beside him, Fang Xuanling's eyes changed slightly, and he subconsciously frowned. It's just that after seeing the emperor not far away, his brows quickly stretched again, and he refocused his attention on a few colleagues next to him.

This son-in-law of his own, Fang Xuanling is still very relieved.

If another person had such contact with King Wu, it might still arouse Fang Xuanling's vigilance, but Li Yuanjia's words...... Hehe, this kid almost doesn't go to court, thinking about craftsmen and businessmen every day, what are you worried about?

Could it be that it is speculated that he conspired to push King Wu to the throne?

Haha, don't be funny!

Not to mention that King Han and King Wu have almost never dealt with each other before, and there is no reason for this at all, just say that with his identity as the prince of the Tang Dynasty, if he is not persecuted, why do he want to do such a thankless thing?

Could it be that if King Wu comes to power, he, the king of Han, will be promoted to one level?

It's already at the top, okay!

Besides, based on Fang Xuanling's understanding of his son-in-law, this kid has no interest in politics at all! And Fang Xuanling firmly believes that this is not only understood by himself, but also by the emperor, and even Sun Wuji, the eldest prince of Zhao State, who is most jealous and hated by King Wu, should also understand!

Sure enough, it was just two or three breaths, and the eldest grandson Wuji took his gaze back and talked and laughed with his colleagues around him again.

"Alas!"

After discovering this, Fang Xuanling's eyelids jumped twice, and then sighed heavily.

There is some relief, but more than that, there is a loss.

Although he knows that he is in Li Yuanjia's position, this is actually a good choice, but Fang Xuanling, who was in the first instance of a scholarly family, still can't get used to these ways of his son-in-law - you are a prince who doesn't worry about eating and drinking, and has a good life, even if you can't get involved in politics, isn't it good to spend more time on piano, chess, calligraphy and painting, especially in academics?

Fang Xuanling remembers very clearly, this son-in-law is a book collector!

Nowadays, the Han Wangfu has a large collection of books and a wealth of various unique books, which is probably second only to His Majesty back then...... Wouldn't it be nice to put a little more thought into this? With Li Yuanjia's talent when he was a child, as well as the talent discovered by Fang Xuanling in daily contact, if he concentrates on learning, he will be a generation of masters!

Famous through the ages, isn't he fragrant?

I just have to study those things...... Even if he knew that the appearance of things such as Quyuan plough and overturning car would be of great benefit to Datang, Fang Xuanling still couldn't let go.

Everything is inferior, only reading is high!

Just when Fang Xuanling's eyes sank and he was a little lost, Li Yuanjia was actively promoting his cement: "Xiao Ke, in fact, in the long run, the cement road is still more cost-effective, because once it is paved, there is no need for people to maintain it every year, even if it is occasionally broken, it doesn't matter, just make up for that small piece with new cement...... Of course, you don't have to be too anxious to try it right now, my people are still experimenting, and it doesn't hurt to wait two or three years. ”

While talking, Li Yuanjia also wanted to slap his thighs here!

Tsk, why didn't you think of it earlier?

There is no way to do it elsewhere, but it is ...... in Luzhou Although it is said that Li Lingkui, the king of Xu, is the assassin of history, but if it is really discussed, isn't it him Li Yuanjia who has the final say?

Li Lingkui, that kid, almost never refutes his brother's words!

Just to build a cement road in the valley outside the city, the frequency of use is still too low, and it is impossible to test the durability of the cement road!

However, strictly speaking, Li Yuanjia's confidence is still very strong.

The reason why cement roads in the future often have to be renovated, that is to say, often break down, is that the daily pressure is too great! A few tons or even tens of tons of cars pass every day, I don't know hundreds of thousands, can it not be broken? But during the Zhenguan period of the Tang Dynasty, the final car was only a few hundred catties, how could it be used badly?

Wouldn't it be the best testing ground if someone was willing to build a few roads?

Merely......

After listening to Uncle Huang's words just now, Li Ke was a little entangled: "But...... Uncle Huang, the cost of building a road is too great, and I am a little scared when you said it just now. ”

"This ...... Yes, indeed. ”

Blinking, Li Yuanjia smiled: "So it's up to you to think about it." But if there were no concrete roads, the carriages would be of little use, especially on dirt roads, which would have been finished with a little rain. ”

“…… Also. ”

The corners of his mouth twitched twice, and Li Ke nodded helplessly.

He still wanted a four-wheeled carriage more than anything else, because after trying it once, he didn't want to ride on two wheels again. But when I think of the weight of the wagon and the condition of the dirt roads......

"If it really doesn't work, let's pave a few stone roads in the city!"

After thinking for a while, Li Ke said with a wry smile helplessly.

"Uh......"

After listening to his words, Li Yuanjia was stunned at first, and then couldn't help but roll his eyes - paving with stone slabs is cheaper than using cement, and this kind of thing can only exist in ancient times, right?

However, he also knew that cement was too difficult to do, not to mention anything else, just a fuel problem could kill people, so even if he looked forward to it in his heart, there was nothing to say at this time.

But on the younger brother Li Lingkui's side, Li Yuanjia is worried about it.

Anyway, Luzhou should be the future Shanxi area, if you spend some effort to find it, there will be no shortage of coal! So while chatting with his nephew casually, Li Yuanjia's thoughts had already flown to his younger brother......

"Uncle Huang, Uncle Huang?"

"Huh? What's wrong? ”

Just when Li Yuanjia was habitually distracted, Li Ke suddenly tugged at his sleeve and reminded in a low voice: "Father...... Father came over. ”

"Huh? Oh good. ”

With a move in his heart, Li Yuanjia hurriedly looked at Li Ke's appearance, and sure enough, he saw Emperor Li Shimin walking over with a happy face: "Haha, what are you uncles and nephews talking about?" ”

After getting up and saluting, Li Yuanjia didn't talk nonsense, and said with a smile: "Xiao Ke met Fang Jun a few days ago, so he also wants a four-wheeled carriage, isn't this asking me again...... By the way, Your Majesty, my brother made another good thing a few days ago in the workshop outside the city! ”

"Oh? What's good? ”

With a raised brow, Li Shimin's interest was immediately aroused.

Not only was Li Shimin interested, but even Li Ke blinked his eyes, looking very curious. In the past few days since he came back, not only did he know about the four-wheeled carriage, but Li Ke also learned a lot about his imperial uncle, and knew that anything that came out of the Han Wangfu would make people's eyes shine and he couldn't put it down.

Not to mention anything else, he really likes mahjong these days!

"Hey, absolutely good stuff!"

Grinning, Li Yuanjia said: "Originally, I wanted to put it in the gift list, but that thing was too easy to break, so the younger brother took it with him, and was ready to hand it over to you in person......"
