"Of course it's true, but we don't have this fruit in the Tang Dynasty, so the Taoist priest should not think about it." Zhang Nan said with a smile.

As soon as he heard that there was no Tang Dynasty, Sun Simiao stopped asking more questions. After all, Zhang Nan was always able to take out some things that people had never seen before. Since this fruit did not belong to the Tang Dynasty, Sun Simiao could not study it.

"Hey, I didn't expect that in such a season, I could actually eat such fresh dishes and fruits. It was really a blessing." Changsun Wuji took a bite of the yellow peach on the cake and said with satisfaction.

It is no wonder that Changsun Wuji would express such feelings. After all, the cultivation capacity in ancient times was not very good, and there was not enough food to eat, let alone fresh vegetables. In this season when spring is not yet available, even half of the nobles would not enjoy it.

As for the fruits Zhang Nan took out, let alone the ministers, even Comrade Li Er did not have such treatment.

When Kong Yingda heard Changsun Wuji say this, he nodded and said, "That's right. I have lived for so many years. This is the first time I have eaten such fresh fruits in this season before spring. Qingquan, where did you get so many fruits?"

Although Kong Yingda often impeached Zhang Nan and Kong Yingda was dissatisfied with some of Zhang Nan's behaviors, Kong Yingda recognized Zhang Nan's talent, and although he did not like what Zhang Nan did, Zhang Nan also did some practical things for the people of the Tang Dynasty. With this, Kong Yingda was not dissatisfied with Zhang Nan.

"Haha, Lord Kong, this is a secret. If Qingquan tells you, wouldn't you be able to eat such fresh things every winter?" Du Ruhui also said with a smile.

When Kong Yingda heard Du Ruhui say this, he also laughed.

"Hey, Qingquan is such a talented person. He can get a lot of ice in summer and fresh vegetables in winter. With this, I, old Cheng, accept it." Cheng Yaojin smiled.

"Hey, actually, this thing is really nothing rare. Isn't it just to eat fresh vegetables in winter? Then wouldn't it be enough to just put a greenhouse?" Zhang Nan said indifferently.

"Green? What is a greenhouse?" Li Eryi looked strange.

Facing Li Er's question, Zhang Nan didn't take it seriously because Zhang Nan suddenly thought of something good.

Although Datang cannot produce a greenhouse with plastic film, it is still possible to build a glass greenhouse. After all, the only thing a glass greenhouse needs is glass with high transparency. Plastic Datang cannot produce it, but glass is OK.

Not to mention anything else, the vertical furnace iron smelting method that has been promoted by Li Er in the Tang Dynasty has been able to melt silica in the temperature of its furnace. Since it can be melted, it is really not difficult to make glass.

Although the heat retention of glass is not good, Zhang Nan believes that this thing can be supplemented by manpower. After all, the Tang Dynasty has the most lacking labor force. The prisoners captured from Goguryeo are now entering the slack season. After all, their number is too large, and the border of the Tang Dynasty is relatively stable, so there is no need for so many people to shoot the city walls.

"Mr. Langjun, the emperor is asking you something." Seeing that Zhang Nan did not respond for a long time, Cui Yue also quietly reminded him below, but he did not expect that Zhang Nan still had a thoughtful expression and ignored Li Er at all.

Cui Yue saw Zhang Nan's appearance and planned to pat Zhang Nan directly, but Li Er made a gesture and stopped him.

So everyone stared at Zhang Nan silently. After a long time, Zhang Nan slapped his thigh and said, "I thought of it!"

Zhang Nan's sudden scream shocked everyone.

"Qingquan, what did you think of? Tell me." Li Er did not blame Zhang Nan for this shocking expression. After all, Zhang Nan rarely showed a thoughtful look in front of him. He could come up with so many good ideas if he laughed in a normal manner, let alone look so serious now.

"Reply to the emperor, I thought of a good thing that can also allow the people of the Tang Dynasty to eat fresh vegetables in winter." Zhang Nan said with a smile.

“!!!”

As soon as Zhang Nan said this, everyone was shocked. After all, the problem of eating a full stomach has just been solved, and he suddenly jumped to the stage where he could eat vegetables in winter. This is the same as the fact that he had just been liberated and had a well-off life.

"Qingquan, you can't say anything nonsense. Where will the crops grow in winter? It's snowy, even if you plant it, the seeds can't even sprout and they will be frozen to death." Li Er frowned. Obviously, Li Er didn't believe that Zhang Nan could make the crops grow in winter. Li Er believed that Zhang Nan could take out some cold-resistant things to plant, but when Zhang Nan said that she could grow vegetables, Li Er didn't believe it.

"I dare not say anything. Your Majesty, do you still remember the weather in Qiongzhou? What is the weather in Qiongzhou?" Zhang Nan asked.

"The weather in Qiongzhou is naturally good. Even in winter, I think it's no different from spring, it's very warm." As a man who has been to Sanya, Li Er naturally likes such weather very much. Although there are typhoons and heavy rains, the high temperature cannot be ignored.

"Then the emperor thinks that the warmth can grow crops?" Zhang Nan continued to ask with a smile.

"Of course... Oh, I understand what you mean. Do you want me to farm there? This is not possible. There are too few people there, and the land is still wasteland. Even if I send people to open the land there, there is no way without a person. After all, the people are unwilling to leave the place where they have lived for generations." Li Er shook his head with a smile.

Moving the people is a huge project, especially Li Er, who is currently in the provinces and prefectures, doesn't think it's enough, let alone moving people to a place where chickens can't lay eggs and birds can't poop.

Although there are now attracting a large number of businessmen because of Huanghuali and seafood, it is a migrant population after all, and it is impossible to count.

"No, no, no, you can think of this good, but my method is much smarter than this one." Zhang Nan smiled.

"Oh? Then what's your method?" Li Er asked.

"It's simple. Since we need the weather in Qiongzhou and Qiongzhou needs our land, wouldn't it be better if we just get the climate in Qiongzhou here?" Zhang Nan said.

"Qingquan, are you talking nonsense? How is Qiongzhou so far away from Guanzhong? What's more, this is the weather." Li Er frowned.

"Your Majesty, what we want is just that warm climate. When we farm, at most, wouldn't it be enough to make such a warm climate for artificial people? Even people can burn fire to keep warm, so why can't food and vegetables?" After Zhang Nan said, everyone's faces appeared with an expression of "There is also such operation."

"As the saying goes, fighting with the sky will bring endless fun, Your Majesty!" Zhang Nan bowed.
