"Well, what about the Eleventh Emperor Uncle?"

After waving his hand casually, Li Ke asked lightly, and at the same time motioned for the saluting subordinates to get up.

"If you go back to the king, I'll be waiting for you in the main hall!"

Han Lucheng naturally didn't dare to slack off, and hurriedly replied.

"Okay, lead the way!"

Li Ke was not surprised, just nodded and took the lead in walking inside. Although he is also a prince, and Li Ke is much better than Han Wangniu in any aspect, he does not dare to have any complaints about Li Yuanjia's lack of greeting.

If it had been a few years ago, the situation would have been different.

At that time, don't talk about an inconspicuous prince like Li Yuanjia, it is a few uncles who have already reached adulthood, and they are not polite when they see Li Tai and Li Ke? Not only to salute your nephews, but even before your nephews salute!

It's just that those good days are gone.

Under the advice of the ministers, the emperor issued a very serious order, not only requiring the sons to deal with the uncles politely, but also to salute before meeting......

No, it's not, they should have to salute, but the uncles don't have to return the salute!

Anyway, except for the crown prince Li Chengqian, everything is on par with the uncle-nephew relationship of ordinary people. So if Li Ke arrived at the gate of King Han's Mansion a few years ago, I'm afraid that this eleventh emperor uncle would be coming up, where would he stay in the main hall and wait for him leisurely like now?

"Huh."

Thinking of this, Li Ke subconsciously pursed the corners of his lips, and then let out a low laugh: "Now that you are in this situation, you still have the heart to think about these things...... Li Ke, Li Ke, your hardships in the past two years have been in vain! ”

After laughing, it was a sigh so low that no one could hear it.

In the past, Li Ke was also a high-spirited master, except for Zhenguan who went to Qizhou for a year for seven years, he basically stayed in Chang'an City. It wasn't until the eleventh year of Zhenguan that Li Ke went to Anzhou again...... He didn't want to go, but this time the emperor was determined not to let him refuse.

It was also this time that Li Ke was impeached for gambling with his nurse's son.

He didn't want to recall the specific situation, but in short, he was dismissed from the government and cut the closure of 300 households, which immediately caused a considerable blow. However, it is precisely because of this incident that when Li Ke went to Anzhou to take up his post again, he suddenly matured a lot......

When you go back to Chang'an City, you won't have the frivolity of the past!

Not to mention, in fact, Li Ke also knows very well in his heart that this eleventh emperor uncle in his family is different from others, at least his father values it very much. Otherwise, just for a carriage and a few pieces of glass, Li Ke thought that he didn't need to make a special trip......

"Huh?"

As soon as he walked into the door of King Han's Mansion, Li Ke sighed lightly, and instantly felt that his eyes were a little insufficient.

Although he is the prince of the Tang Dynasty, and he is also a prince whose status is faintly higher than that of ordinary princes, coupled with the noble background of his mother's family, Li Ke almost stood at the top of the pyramid of this era as soon as he was born.

However......

After walking into the Han Palace, Li Ke was still shocked by what he saw.

Needless to say, the glass on the doors and windows of the house, Li Ke had already known about this kind of novelty from others, and he had seen it with his own eyes when he came back to meet his father; The four-wheeled carriage is nothing, he has also taken a closer look at Fang Jun's side before, after all, one of the main reasons for visiting the imperial uncle this time is that!

But even so, seeing so much glass, Li Ke was still a little shocked!

This thing, even the East Palace has not seen a few sides!

Especially before coming, Li Ke had already inquired, so far there are only a few companies in Chang'an City that use glass, except for Sun Wuji, the eldest prince of Zhao State, the others are Li Yuanji's relatives......

But at this moment, there are at least a dozen sides just to see, right?

And this is not the most curious thing for Li Ke, after walking more than a dozen steps inside, the young King Wu finally didn't hold back, and squatted down with the hem of his clothes: "What the hell is going on on this gray and hard ground?" ”

Although he didn't specify who to ask, Han Lucheng naturally hurriedly whispered: "Back to the king's words, this road ...... Well, it's paved with cement. ”

"Cement? What is cement? ”

After being stunned for a moment, Li Ke looked at Han Lucheng in amazement.

Why is this name so weird?

"This ......"

After his eyelids jumped for a moment, Han Lucheng replied helplessly: "If you go back to the king, cement is actually a good ...... Well, the mixture of several materials is called cement because it is soft and sticky when water is added, like soft mud that has rained...... It was paved on the road while it was wet, and when it dried, it looked like this! ”

"Huh? What kind of things are mixed? ”

“……”

Seeing that King Wu bent down with great interest and picked the cement floor with his hands, and continued to ask about the cement, Han Lucheng's heart suddenly sudden, and he quickly shook his head and said: "King, the little one only knows a little bit of fur, and I still have to ask my king if I want to ask the king!" ”

After finishing speaking, Han Lucheng hurriedly lowered his head.

Zhang Wan and his research time is not short, almost every month to build a few small sections of road in the house, and then test the performance of the new cement formula.

For this kind of thing, the cost of Han Road is not very cold, because the cement road built in front is either too soft, even if it is dry, it can't withstand the big car; Either it's too brittle, it doesn't take long to crack one after another, and the cost of firing cement is not low, so in his opinion, there is no stone or green brick to use.

But recently, Han Lucheng's views have changed a little.

The main reason is that the cement that Zhang Wan took out suddenly made a big stride, and after three months of paved roads, it is still the same as the one just paved! The king was happy, and directly asked them to pave hundreds of long roads in the palace, saying that they wanted to see how long they could last......

In this case, why didn't Han Lucheng know the importance of this thing?

"Oh?"

With a slight raising of his eyebrows, Li Ke glanced at Han Lucheng, and his face suddenly sank.

He knew that the other party didn't dare to say it.

However, after suppressing the unhappiness in his heart, Li Ke became more and more interested in the cement pavement under his feet - it was very hard, very flat, and it looked very strong, which made him extremely curious!

Subconsciously stomped his feet, Li Ke asked; "This kind of road...... Afraid of rain? ”

"Back to the king, don't be afraid!"

Secretly relieved, Han Lucheng hurriedly replied: "This cement road is not only not afraid of rain, but it is also about the same as a stone road in terms of hardness......
