"That's right, this dining place is made of water jade, and I wanted Qingquan to build one in my palace too, but in the end, I forgot about it in a hurry." Li Erdao.

"That's right, Qingquan, your house made of water jade, I think it can be used as the house you said to build for crops." Fang Xuanling also raised his head and looked at the transparent ceiling and said.

After Zhang Nan listened, he nodded and said: "Actually, that's what I said, in fact, this thing is called glass inside our passage door, your Majesty, guess what material this thing is made of." ”

"Water jade, water jade, is naturally quarried out of stone." Li Erdao.

"Yes, but not entirely, this thing is essentially the same as stone, but it's made of sand." Zhang Nan explained.

"Sand? Qingquan, don't lie to me, although I am not good at this, but how can the sand be made into such a translucent water jade? Li Er's face was puzzled, obviously Li Er couldn't associate the soft and loose sand with the translucent glass.

"Although you don't believe it, Your Majesty, it is true. Your Majesty, think about it, even iron can be refined from stone, why can't this thing? Zhang Nan said.

"Then according to your words, this thing is the same price as sand?"

"Almost, at that time, the minister also thought about taking these things to other countries to exchange money, but our Datang is really fast, and in the blink of an eye, there are few rich countries around." Zhang Nan also patted Comrade Li Er's ass a little.

Sure enough, hearing Zhang Nan's words, Li Er immediately smiled, and now Comrade Li Er likes to listen to others exaggerate the strength of the Tang Dynasty, because Li Er feels that the strength of the Tang Dynasty is inseparable from his wise leadership.

"Eh, Qingquan, what you said is not right, you look at the Yuan-Ri Dynasty meeting some time ago, there are still so many countries that come to worship my Tang Dynasty, how can it be said that there is no country? But can this thing really make money? Li Er wondered.

"Your Majesty, when you didn't know that this thing was made of sand, how much did you think it would cost to build a room like this?" Zhang Nan asked rhetorically.

"This ......"

It is true that as Zhang Nan said, when he didn't know that this thing was made of sand, Li Er felt that building a house with such a translucent water jade was simply astronomical, Li Er didn't even dare to think about it, but after knowing that the raw material of this thing was sand, Li Er was not so good at it, how much money can such a room of sand be worth? How much is sand worth for a hundred houses?

"So, we know that this thing is burned out of sand, so let's buy the little things that are burned out to countries that don't know that this thing is burned out of sand, and that's definitely a lot of money, Your Majesty." Zhang Nan said.

"Well, I think this plan is feasible, not bad, but how do you burn this thing?" Li Er nodded with satisfaction, and exchanged the sand for real money from other countries, Li Er felt happy when he thought about it.

However, Zhang Nan's answer made Comrade Li Er regret why he asked him.

"I don't know."

“...... What don't you know? Li Er asked with a dark face.

"The minister doesn't know how to burn glass, the minister only knows that this thing is made of sand."

“......”

As soon as Zhang Nan's words came out, he also fell through the eyeballs of the people present, and he just said a lot of rambling words, all of which are talking about calves here? I can't do it at all, so what's the use of talking about it?

Sure enough, looking at Comrade Li Er's expression that was about to go crazy, Zhang Nan also hurriedly said: "But the minister can learn, the emperor, you can rest assured, this thing is simple, and the minister promises to burn the glass within a month." ”

After getting Zhang Nan's guarantee, Comrade Li Er's face eased, Li Er was already planning to go crazy, but now that Zhang Nan has made a guarantee, Comrade Li Er doesn't have anything to say, after all, Zhang Nan's guarantee is still very valuable in Comrade Li Er's eyes.

"In that case, I'll hand over this matter to Qingquan you, ask for money for money, ask for people to give people, in short, to get this thing out for me, and when it's fired, Cui Shao, you can hand me a fold, I want to know how much I can make if these things are sold to other countries." Li Erdao.

Now Comrade Li Er has moved towards a businessman, and he is also a wealthy businessman, if the profit is small, then Li Er will absolutely disdain, such as Zhang Nan's clothing store, if it was put in the past, Li Er would have to find a way to participate in a share, but now with the racecourse, and private clubs, as well as the support of other industries, Li Er's small treasury is also very rich.

Not to mention the value generated by forcibly sending fresh blood to Datang by capturing prisoners, now Datang's taxes in one year are worth the taxes of the previous five years, and Zhang Nan's cement road has also begun to radiate towards the major state capitals with Chang'an City as the central point, after all, Datang will not let those captives eat rice, so a large part of the captives are engaged in infrastructure construction for Datang.

"Okay, let's talk about this matter here, today is the hundred-year-old of the four little guys, it's not appropriate to talk about political affairs, let's put these things on the morning court." Li Erdao.

Hearing Li Er say this, everyone was naturally happy.

"By the way, Qingquan, when this hundred years old is so important, you can take out one to eat, I'm afraid it's not very suitable." Li Er suddenly thought that he had just asked Zhang Nan to offer treasure, and he was almost fooled by Zhang Nan with a cake, although this cake was delicious.

"Yes, yes, Qingquan, hurry up and get your gift, I can't wait." Li Yuan also hurriedly said, the cream on his beard had not been wiped clean, and his mouth shook when he spoke with Li Yuan.

"Your Majesty, the ministers have come up with something that is so beneficial to the country and the people, and you still want the ministers to offer treasures, this is not old and appropriate." Zhang Nan also said with a bitter face, because Zhang Nan really didn't think of giving anything to these four little guys.

"Then what's the matter, even if you don't give anything to the pheasant slave and the son, don't you even give Junyan and Zhenzhen's gifts?" Li Er's righteous words said that Zhang Nan almost believed it.

In fact, Li Er's words should be listened to in reverse. Even if you don't give anything to your son and daughter, then you won't even give gifts to my son and daughter?

"Then the emperor, you can also let the ministers think about it, there are too many strange things that I have passed through the door, and I don't know what to take out for a while." Zhang Nan said.

"Then you thought, before I finish eating this cake, you'd better come up with it for me." After speaking, Li Er took a bite into his cake, and a third of this bite was gone.

"Are you eating or pouring?" Zhang Nan looked at Li Er's blood basin and shouted in his heart.
