"This is the reason why I want Your Majesty to occupy the land of Linyi and the Wa Kingdom." Xia Hongsheng ignored Li Shimin's shock and said to Li Shimin: "This piece of land, the only people known in the world today are His Majesty, the prince and Weichen. If Datang wants to prosper forever, the first thing to ensure is the people's food. There are hundreds of kinds of grains and vegetable crops here, if they can be planted in Datang, they can make Datang no longer lack of grain, and there will be no famine. And if you want to get these crops, you have to find a way to go to this land. And there are only two ways to get to this land. ”

"Sea vessels?" Li Shimin looked at the map and said, "But this place is tens of thousands of miles away from my Tang Dynasty, how can there be a sea ship that can sail so far?" ”

"Yes, with our current ships, it is indeed not possible. This requires a kind of tree in Linyi Country, which is the most suitable for shipbuilding, and the sea ships made of this kind of tree will not rot all year round, so that they can be competent for such ocean voyages. Xia Hongsheng nodded and said to Li Shimin: "If you don't use a sea boat, you need to go north, pass through Liaodong to the Liugui Country, continue to go north, and get here...... The name of this place is called the Yaksha country, and along the Yaksha country to the northeast, His Majesty saw that between these two lands, this place is the closest distance. In winter, it is extremely cold here, and it freezes for a long time, and it can pass over the ice, and as for this place, it turns south and ends here. It's just that this move is particularly dangerous, much more dangerous than the sea ship. The Yaksha country is extremely cold, spitting, and as soon as it leaves his lips, it has become ice, and the ice is also extremely dangerous, and there are many white bears. And by sea, in addition to the timber of Linyi Country, it is also necessary for the seaport to be able to transfer sea vessels. The land of Yizhou in the Tang Dynasty and the four islands of the Wa Kingdom can be used as the gateway to the sea of the Tang Dynasty. ”

"These things...... How do you know all this stuff?! Li Shimin was surprised: "Isn't it true that someone walks in the sky to see the whole picture of the world?" It's a blink of an eye, but everywhere, you know about the local things?! ”

"Where can I be!" Xia Hongsheng shook his head and said: "These are all the accumulations of thousands of years in China, but they are all discovered by people little by little, some of this and some of that and some of them have summarized this and recorded them, and they have accumulated for thousands of years before they have made these discoveries." ”

"This ...... Just like this place, so far away, inaccessible by sea ships and unreachable by manpower, how can anyone come here? If you know that there is a crop here, can you pass it back? Li Shimin pointed to a map of South America and asked.

Uh, don't bother with those details...... Xia Hongsheng scratched his head, rolled his eyes, and explained: "Naturally, someone knows. Didn't Your Majesty hear that there is a biography of Fusang in the Book of Liang, which is about this place? ”

"Fuso?" Li Chengqian interjected: "Isn't Fusang the Wa Kingdom? ”

Of course Xia Hongsheng knows, but doesn't this have to be justified, otherwise Li Shimin would have been entangled in the question of how this map came out.

The country of Fuso, which is not controversial in modern times, refers to Japan. However, in ancient times, there was no specific name for Fuso, one for Japan and the other for Mexico.

The person who first advocated the idea that Fuso was Mexico was a Frenchman named Jin Quan, who submitted a study in the eighteenth century and said that according to Chinese historical books, in the fifth century A.D., people from China had already arrived in Fuso, and Fuso, he thought was Mexico. Among Chinese scholars, the first to respond to this argument was Zhang Taiyan, who also identified Fusang as Mexico in his book Wenshi. The Chinese history book that Jin Jian refers to refers to "The Book of Liang and the Biography of Fusang". According to this theory, Fuso should be far away in the Americas in the Western Hemisphere. This is because cotton, which is native to Mexico, has all the characteristics described in the "Book of Liang: The Legend of Fuso". In addition, the leader of the Maya people in Mexico was called "Dui-Lu," which is pronounced exactly what the nobles of the Fuso country mentioned in the Book of Liang: the size of the "Lu". Fuso has two prisons in the north and south, the south prison for minor offenders, the north prison for felons, the children of repeat offenders, boys are enslaved at the age of eight, and girls are enslaved at the age of nine, which is also the system of the Maya people in Mexico.

"Not really." Xia Hongsheng shook his head: "It's a pity that his person has passed away, otherwise, he would be able to tell His Majesty about the exotic customs." ”

"And how do you know these things?" Li Shimin asked.

Xia Hongsheng scratched his head: "My master is a hermit in the mountains, and hermits often communicate with each other, so they know a lot of things, so they teach Weichen, and Weichen naturally knows." Seclusive masters will also talk to each other about what they know, this is called mutual communication, as the so-called you have a cup of grape wine, I have a bowl of three le pulp, everyone ignores each other, then you only taste grape wine, I only taste three le pulp, if we communicate with each other, then you and I have both drunk grape wine, but also tasted three le pulp...... Therefore, the master will often communicate and talk about the knowledge they know, so everyone has this knowledge, and the knowledge is broader. ”

Xia Hongsheng talked nonsense in a serious way, and after a big circle, this pot was pushed to those unwarranted Junshan hermits.

"Sure enough, he is worthy of being a master in the mountains! That's a great deal! Li Chengqian slapped a divine assist at this time and smoothly changed the topic: "In the past, everyone was too self-cherishing, and they hid all knowledge and technology by themselves, resulting in the loss of many things. Fortunately, after the implementation of the patent law, it is much better now. ”

Following Li Chengqian's attention, Xia Hongsheng said to Li Shimin again: "Your Majesty, you still have to keep this drawing, I'm afraid that within ten years, it won't be needed for the time being." ”

Li Shimin is a man of great talent, excited but not impulsive, after listening to Xia Hongsheng's words, he nodded, and said: "Yes, the road must be taken step by step, and each step must be solid in order to go further." The current plan is to enhance the national strength of the Tang Dynasty, not to be ambitious - I want to hang this picture in front of the couch in the study, and look at it from time to time as a spur! ”

"Your Majesty is wise!" Xia Hongsheng hurriedly slapped his ass on the back: "To strike iron, you must be hard first!" His Majesty is not impulsive, and he can keep his feet on the ground, which is the best. ”

"Good! A good sentence 'striking iron first needs its own hardness'! Li Shimin's eyes lit up, and he said with a smile: "Xia Qing, I really deserve the title of immortal in the market, my Tang Dynasty has Xia Qing's help, and I will be able to live forever!" It is also a blessing for my Li family to be able to get Xia Qing's righteousness! Xia Qing will live up to me, I and the Tang Dynasty, and the Li family will also live up to Qing! I will be rewarded for my dedication and advice! (To be continued.) )
