The October day in Chang'an City is already considered to be winter.

Although it had not snowed yet, the temperature was not high, and even if the sun was shining in the sky, the courtiers were still wearing a lot of clothes, and many of them wore woolen sweaters under their clothes.

The Daming Palace itself is the terrain of high and low in the front, and the Hanyuan Hall is built on Longshou Mountain, and when Li Kuan asked Yan Liben to design, it was raised up a zhang high.

Therefore, as soon as you enter the Danfeng Gate, you can intuitively feel the majestic momentum of the Hanyuan Palace.

Li Yuan can be regarded as a person who is accustomed to seeing the world, and his face does not change along the cement road, step by step, and goes straight to Hanyuan Palace.

"Imperial grandfather, this Hanyuan Hall is more than five zhang high, it is the highest building in the entire Daming Palace, standing in the hall, you can see the situation of the entire front palace."

In the Daming Palace, there is a palace wall that separates the front and rear palaces, so although the place where the harem is located is relatively low, it cannot be seen in the Hanyuan Palace, which is also for the sake of privacy.

"More than five feet? This is two zhang higher than the Taiji Palace, it should not be easy to find such a large giant tree to build a palace, right? Could it be that this is the rumored use of concrete technology to make it? ”

Although it was difficult for Li Yuan to see the courtiers and he couldn't walk around outside the palace at will, he still knew some news about Chang'an City, especially for a while, when the construction delay of the new palace was hyped up, Li Yuan made people inquire about the situation.

So at this moment, when he said the word concrete craft, Li Kuan didn't think it was strange.

"Grandfather Huang, it's true, it's because of cement that this Hanyuan Hall can be built so high."

Li Kuan supported Li Kuan, crossed the threshold of Hanyuan Palace, and entered the hall.

"Huh?"

Li Yuan looked around and couldn't help but let out a sound of surprise.

This Hanyuan Hall is so spacious and bright, there is no dark feeling at all.

The most important thing is that it was a little cold just now, but now it is only a few steps into the hall, and I feel that the inside of the hall is much warmer than the outside.

Li Yuan's eyes swept around, but he didn't find a coal stove.

On the contrary, a transparent scene on both sides of the main hall caught his attention.

"Could it be that you really used the glass used to make mirrors to build the Daming Palace?"

Although Li Yuan had also heard this kind of rumor, he originally thought that there was some glass in the key place at most, but how could he ......

The entire Hanyuan Hall is almost transparent on both sides, but between the glass and the glass, there are some frames.

How much glass does this have to use?

Li Yuan couldn't help but walk towards the side of the main hall.

Even Li Yuan, the former emperor, was so surprised, let alone his reaction.

"Big brother, the second brother came out of such a Daming Palace, and robbed you, His Royal Highness the Prince, of the limelight, so you don't have any opinion at all?"

Li Tai was also shocked in his heart, but he did not miss the opportunity to provoke the relationship between Li Chengqian and Li Kuan.

If this Li Kuan hadn't been passed on to Li Zhiyun, maybe this sowing discord would have been successful.

In all dynasties, the position of the crown prince was relatively embarrassing.

As a prince, if his actions are too big, the people on the throne will have opinions.

But if there is no movement, the other brothers will have ideas in their hearts, and there will be all kinds of actions.

Not to mention the crown prince of the Tang Dynasty, look at Li Jiancheng......

"Hmph, the second brother is filial, I'm the eldest brother, it's too late to admire, how can I have an opinion?"

Li Chengqian is not stupid, so naturally he will not let Li Tai's treacherous plan succeed.

"I heard that the eldest brother invited the second brother to the East Palace for banquets many times, but it didn't work out once."

"Hmph, the fourth brother is saying bad things about the second brother behind his back, and at the same time he takes the initiative to recruit him, I'm afraid this will damage your image as a gentleman, right?"

"Big brother, to put it mildly, in this court, apart from you and my brother, who else is worthy of the second brother? But he didn't care about it anywhere, don't you think he might have something else in mind? ”

Li Tai faintly felt that he probably had no chance to recruit Li Kuan, so he kept giving him eye medicine.

And when Li Chengqian and Li Tai were whispering, Li Yuan was already standing in front of the glass wall, feeling the cold touch of a handful of glass with his hand, and Li Yuan couldn't help but feel very satisfied with this palace.

"Kuan'er, let you break the bank!"

The construction funds of Daming Palace are said to come from the city port tax, but Li Yuan does not need to understand it specifically, and he also knows that the city port tax that was only levied this year is definitely not enough for the construction of Daming Palace, and the Chu Wangfu must have advanced a lot of funds first.

In the future, whether the city tax can make up for this deficit, except for Li Kuan himself, everyone else basically has no confidence.

Hanyuan Hall used a lot of glass, and this original rumor became a reality, which not only shocked Li Yuan and Li Shimin.

It surprised the courtiers who followed.

Generous!

It's definitely a big deal!

His Royal Highness the King of Chu, it can't be that there is a problem with his brain, right?

Not to mention taking the initiative to take over the construction of Daming Palace, it is still so luxurious.

Li Zhiyun is long gone, otherwise......

Yang Benman was still a little depressed just now, but now when he saw the glass on the wall of Hanyuan Palace, he was suddenly in a good mood.

The more Li Kuan is a loser, the happier he is.

It's best to defeat the Chu Palace, and your own breath will be over.

"This King of Chu, I have to talk about him well when I turn around, filial piety is due, but it's not this law, if my daughter marries him......"

Cheng Yanjin followed behind the large army, and he also complained in his heart.

My daughter's daughter goes out every once in a while, and the frequency is significantly higher than in previous years, with Cheng biting gold on the surface, she is actually shrewd and dying, how can she not investigate what Cheng Jingwen is doing?

Li Kuan has no parents and brothers in his house, and his daughter has married and is a stable hostess.

So although Cheng Yanjin knew about Cheng Jingwen, he didn't object.

Of course, it is necessary to wake up your daughters openly and secretly not to do anything out of the ordinary.

This year, it is not popular to give birth to a baby who has participated in the wedding of his parents!

Li Shimin followed behind Li Yuan, in addition to being shocked, he actually felt a little envious in his heart.

The conditions of this Hanyuan Hall are much better than those of the Taiji Palace, needless to say, the warmth of the winter is like spring, and it seems that his back is beginning to sweat.

"Kuan'er, it's so warm in this Hanyuan hall, but why haven't I found a furnace?"

Li Shimin saw that Li Yuan's forehead also began to sweat, and couldn't help but ask.

And after Li Shimin asked like this, many ministers around him who were excited also found out, hey, they were actually sweating?
