Tan Yun explained here that he did not grow this family when he was a child, and because his family was poor, he would not buy this kind of fruit that could not be eaten, so he naturally never saw it.

"Okay, no wonder you are serious nonsense." Cao Yi nodded and complained.

"No!" Tan Yun blushed, and even the cucumber on his hand was not eaten. He said coquettishly: "Dan Yun has never seen it, so he had to guess based on his own cognition. There are indeed many things in the world, which were tender and light when he was a child, but when he grew up, the color would become darker and darker when he was a child. Look at the little ducks and chicks, they were light yellow and tender when they were a child. When they grew up, the color of the feathers would become darker, gray, black. Young Master, don't you teach us to be brave enough to imagine and guess..."

After saying that, he pouted his little mouth. If he hadn't subconsciously raised the cucumber in his hand and stuffed it into his mouth, Cao Yi would have really coaxed him.

"Hahaha, okay, what you said is right. Your behavior of being brave enough to imagine and guess is very good, and it is still very worthy of encouragement. But this time you guessed wrong. This cucumber is not born and raised in our Central Plains or the Han Kingdom. It is an alien species."

"Exotic species? What does this mean?" Tan Yun asked with his head tilted.

Even Liu Baiqing turned around with interest and planned to listen carefully to what the young master explained. He had inexplicable curiosity and resonance with the words "exotic" and "species".

"In fact, it means literal meaning. Species, which actually means objects and species. Here it refers to cucumbers, which are foreign. As I said just now, it is not something native to the Han people. It was transmitted from the Western Regions."

"Western Regions? Is it the current Western Region?" Liu Baiqing asked.

"Well, the place is the place now, but time is not the time now." Cao Yi originally wanted to show off his extensive knowledge, but then he realized that the cucumber had been planted in the Central Plains for so long, so others naturally knew that it was not the time now, and his face was slightly red at the moment. Fortunately, neither Liu Baiqing nor Tan Yun noticed his embarrassment, and he was covered up by his laughter.

"Do you know Emperor Wu of Han?" Cao Yi asked quickly.

"I know!" Liu Baiqing nodded excitedly. After all, during the reign of Emperor Wu of Han, it can be said that the Han people were the most powerful.

At that time, this Emperor of Eternal Famous, who was famous in history, left a famous saying, "Those who offend me, who are strong Han will be punished even if they are far away!" The military strength of the Han Dynasty at that time also reached its peak, and they fought against the Huns and the Hu people so hard that they dared not invade the border and stay away from the territory of the Han Dynasty. This is a scene that every soldier yearns for, and naturally the same is true for Liu Baiqing.

After hearing this name, Tan Yun was confused. For her, she had only been taught some books such as the Four Books and Five Classics, "Women's Training" and "Women's Commandments", and only reached the level of literacy in stating the text. At most, she read some poetry books. She had never read the history and history records before.

Not to mention Emperor Wu of Han, the Han Dynasty, which was nearly a thousand years ago, even Tan Yun, the previous official and founding emperor of this dynasty, could not tell the name of Tan Yun. As for the current emperor, it was only known to others when they talked about it.

In order to take care of Tan Yun, Cao Yi explained: "In fact, nearly a thousand years ago, our country was under the control of an emperor named Emperor Wu of Han. At that time, he ordered a minister named Zhang Qian to take more than 100 people to the Western Regions to open up the Silk Road. The Silk Road actually transports the silk from our side through the Hexi Corridor to the countries in the Western Regions and sells it at a high price, and then transports the goods we do not have on them back. The trade route is called the Silk Road. Do you understand this?"

As Cao Yi spoke, the saying "Silk Road" emerged, but after all, it was given by modern scholars. In this era, there was no such statement, so Cao Yi also explained it consciously.

"I understand, I understand, young master, did the cucumber be brought to us at that time?" Tan Yun said excitedly.

Cao Yi nodded and said, "This is indeed the case. After Zhang Qian returned from his mission to the Western Regions, he did bring back many things we didn't have, such as good horses, lions, camels, ostrichs and other animals. These things we didn't have before were all brought back by Zhang Qian at that time."

"These are all animals, what about eating? Why don't you say anything like cucumber?" Tan Yun was indeed interested in eating, and was already anxiously asking Cao Yi's question.

"Of course there are some foods, otherwise how can you eat the cucumbers in your hands? At that time, I brought a lot of food, such as grapes, alfalfa, walnuts, pomegranates, flax, beans and courgettes, etc."

"Ahhhh, grapes, and pomegranates are all loved by Tan Yun. They are very sweet, but the walnut, flax, beans, courgettes, and the ones are called...

…Is alfalfa? These are all fruits?" Tan Yun asked in confusion.

Cao Yi chuckled softly: "Don't worry, I'll answer you one by one. Alfalfa is the golden cauliflower on our side. You always know this."

Tan Yun nodded obediently. She knew that fried golden cauliflower and pickled golden cauliflower were her favorite dishes.

"As for the others, walnuts are walnuts, flax is square stem, also called stew, and then beans are broad beans. As for cucumbers, they are the cucumbers you are eating now." Cao Yi pointed at the cucumbers that Tan Yun was eating and said with a smile.

Tan Yun glanced at the cucumber in his hand again and asked in confusion: "Young Master, why did I hear what you said? Those who came from the Western Regions before were all with the characters "Ni"? Why did they change their names later?"

"That's also related to history. You know, before this dynasty, there were the Five Dynasties and Ten Kingdoms, before the Li Tang, Yang Sui, and before, there were the Five Barbarians and the Sixteen Kingdoms and the Wei, Jin, Southern and Northern Dynasties. At that time, the Jin Dynasty was still the one who ruled the world, but the emperor was an idiot at that time. Then his wife controlled the government and messed up the country, so the Eight Kings Rebellion broke out, which greatly damaged the vitality of the Jin Dynasty. Later, the Xiongnu Liu Yuan called the emperor, and the country was named Han, and then the Western Jin Dynasty was destroyed. The five Hu people who originally entered the Central Plains, namely the Xiongnu, Xianbei, Jie, Di, and Qiang, formed the "Five Liang: Fore Liang, Northern Liang, Western Liang, Later Liang, Southern Liang", "Four Yan: Fore Yan, Later Yan, Southern Yan, Northern Yan", "Three Qin: Fore Qin, Western Qin, Later Qin", "Two Zhao: Fore Zhao, Later Zhao" and the Xia regime in the north, and the Chenghan regime in the south. "Sixteen countries."

"So many! Sixteen countries and five Hu people, you are so amazing! You can write down all of this word!" Tan Yun exclaimed, and unknowingly patted Cao Yi's flattery. Even Liu Baiqing looked at Cao Yi with admiration. As long as it was about reading, writing poems and lyrics, the young master said that no one would dare to be the second. Both of them thought so.

"This story of the change of Hu Gua to cucumber is in the Later Zhao country among the Sixteen Kingdoms. Because the rulers were all Hu people at that time, you also know that Hu people were the names of our Han people who had a contemptuous nature towards their northern nomads. Because they often did not care about details, did not like to be clean, and had long beards. We Han people despise them more and thought they were all rude people, so we called them "Hu people". " Cao Yi also picked up a cucumber, took a bite, chewed a few bites, and continued.
