"Yes, this place for meals is made of water and jade. I wanted Qingquan to build one in my palace at that time. In the end, I forgot about this matter after a hurry." Li Erdao.

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

After hearing this, Zhang Nan nodded and said, "Actually, this is what I mean. In fact, this thing is called glass in our time travel door. Your Majesty, guess what material this thing is made of."

"Shui jade, water jade, is naturally picked from the stone." Li Erdao.

"Yes, but not entirely right. This thing is essentially the same as a stone, but it is made of sand." Zhang Nan explained.

"Shazi? Qingquan, don't lie to me. Although I am not good at this, how can sand be made into such a transparent water jade?" Li Er looked puzzled. It was obvious that Li Er could not associate the soft and loose sand with the transparent glass.

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

"In your words, this thing is the same as sand?"

"It's almost the same. At that time, I also thought about taking these things to other countries for money, but our Tang Dynasty fought too quickly. In the blink of an eye, there were not many wealthy countries around." Zhang Nan also flattered Comrade Li Er a little.

Sure enough, when Li Er heard Zhang Nan's words, he immediately smiled happily. Comrade Li Er now likes to listen to others exaggerate the power of the Tang Dynasty, because Li Er feels that the power of the Tang Dynasty is inseparable from his wise leader.

"Hey, Qingquan, what you said is wrong. Look at the New Year's Day celebration some time ago, there are still so many countries that came to worship my Tang Dynasty. How can you say there is no country? But can this thing really make money?" Li Er said in confusion.

"Your Majesty, when you didn't know that this thing was made of sand, how much does it cost to build such a house?" Zhang Nan asked back.

"this......"

It is indeed as Zhang Nan said, when he didn't know that this thing was made of sand, Li Er thought that building a house with such transparent water jade was simply an astronomical figure. Li Er didn't even dare to think about it. However, after knowing that the raw material of this thing was sand, Li Er was not so human. How much money can a room of sand be worth in such a room? How much money can a hundred houses be worth?

"So, we know that this thing is burned out of sand, so we can buy the small things that are burned out of burnt out of the country where we don't know that this thing is burned out of sand. That will definitely make a fortune, the emperor." Zhang Nan said.

"Well, I think this plan is feasible, it's good, but how do you burn this thing?" Li Er nodded with satisfaction and exchanged sand for real money from other countries. Li Er felt happy after thinking about it.

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

"have no idea."

"...You don't know what?" Li Er asked with a dark face.

"I don't know how to burn glass, I only know that this thing is made of sand."

“…”

As soon as Zhang Nan said this, it also fell into the eyes of the people present. He said a lot of things just now, all of whom were talking about it? He didn't know how to do it at all. What's the use of saying it is so vague?

Sure enough, seeing Comrade Li Er's expression about to get angry, Zhang Nan also hurriedly said: "But I can learn it, please don't worry, yourselves, this thing is simple, I promise to burn out the glass within one month."

After getting Zhang Nan's guarantee, Comrade Li Er's expression calmed down. Li Er had already planned to get angry, but now that Zhang Nan has made a guarantee, Comrade Li Er doesn't have to say much. After all, Zhang Nan's guarantee is still very valuable in Comrade Li Er's eyes.

"Since that's the case, I will hand over this matter to Qingquan. I want money and people to give it to me. In short, I have to make this thing out. After it is burned, Cui Shao, please give me a note. I need to know how much money I can earn if these things are sold to other countries." Li Erdao.

Comrade Li Er is now moving towards businessmen, and he is a wealthy businessman. If the profit is small, Li Er will definitely disdain, such as Zhang Nan's clothing store. If it were placed in the past, Li Er would have to find a way to join the company. However, now with the racecourse, private club, and other industries, Li Er's small treasury is also very rich.

Not to mention the value generated by forcibly transporting fresh blood to the Tang Dynasty by capturing prisoners. Now the annual tax of the Tang Dynasty is worth the tax of the previous five years. Moreover, Zhang Nan's cement road has also begun to radiate towards major prefectures with Chang'an City as the center point. After all, the Tang Dynasty will not let those prisoners eat nothing, so a large number of the prisoners are doing infrastructure for the Tang Dynasty.

"Okay, let's talk about this matter here. Today is the 100th anniversary of four little guys. It's not appropriate to talk about political affairs. Let's talk about these things in the morning court." Li Erdao.

When everyone heard Li Er say this, they naturally enjoyed leisure.

"By the way, Qingquan, when this hundred years old is so important, you should take out a food, which is probably not very suitable." Li Er suddenly thought that he had asked Zhang Nan to offer treasure just now, and Zhang Nan almost fooled it with a cake, although this cake was delicious.

"Yes, yes, Qingquan, come out your gift quickly, I can't wait." Li Yuan also said hurriedly, the butter on his beard had not been wiped clean, and his mouth trembled as he spoke with Li Yuan.

"Your Majesty, I have brought out such a thing that is beneficial to the country and the people. You also want me to offer treasures. It's appropriate to be old." Zhang Nan also said with a bitter face, because Zhang Nan really didn't expect to give these four little guys anything.

"How can you do it? Even if you don't give things to Zhinu and Yizi, don't you even give Junyan and Zhenzhen's gift?" Zhang Nan almost believed Li Er's righteous expression.

In fact, Li Er should listen to what he said the opposite. Even if you don’t give your son and daughter things, will you not even give me my son and daughter’s gifts?

"Then you, please think about it. There are too many strange things I have traveled through the time sect, and I don't know what to do for a moment." Zhang Nan said.

"Then you think, before I finish eating this cake, you'd better think it out for me." After saying that, Li Er bit his own cake, and one-third of it disappeared after one bite.

"Are you eating or pouring things?" Zhang Nan shouted in his heart as he looked at Li Er's bloody mouth.
