Li Shimin took two steps forward curiously and began to examine the sphere carefully.

He saw that there were words on the seven strange patterns that he didn't see clearly, which were written in Asia, Europe, and South America...... As for the blue places, they say the Pacific Ocean, the Indian Ocean, or something.

Li Shimin reached out and touched the sphere, and found that there was a strong sense of concave and convex, and then knocked lightly, the crisp sound showed that the inside of this thing was hollow.

"Porcelain?" Li Shimin looked at Li Yuanba with a stunned expression.

Li Yuanba said a little proudly: "Brother Huang, this sphere is a fine porcelain made by the courtier's brother who ordered someone to go to Changnan Town and fired it several times!" ”

Changnan Town is actually Jingdezhen, Jingdezhen belongs to the eastern border of Chu in the Spring and Autumn Period, Qin is the county of Jiujiang County, Han belongs to Poyang County, Yuzhang County, and the Eastern Jin Dynasty is called Xinping Town.

Tang Wude placed Xinping County in four years, Xinping Town belonged to it, in the south of the Changjiang River, also known as Changnan Town. Wude withdrew from the county in eight years, and the name of Changnan Town was restored.

"No wonder!" Li Shimin nodded thoughtfully and said, "But what is this thing?" ”

With the instinct of fighting for many years, Li Shimin thought that this was a map, but even if he thought about all the state capitals and counties of the Tang Dynasty, he didn't search for a place called Asia or North America in his mind, and he didn't even think about the surrounding states, but he didn't have it.

Li Yuanba did not answer Li Shimin's words, but asked a question: "Brother Huang, do you know how big the world is?" How vast is this world? ”

Li Shimin furrowed his brows and said, "As far as I know, in addition to the Tang Dynasty, which has infinite territory, there are also Persia, Tianzhu, and Great Eaters thousands of miles away...... If you want to go all these countries around, I'm afraid it will take more than ten years! As for this heaven and earth, it is a place that we Tang people can reach. Isn't it all heaven and earth? ”

Li Yuanba shook his head and said: "There is a saying in ancient times, this heaven and earth are round places, that is to say, the heaven and earth under our feet are round, like starting from Chang'an City. If you walk in a straight line around the ground under your feet, after many years, you will find that the end point is also Chang'an City! ”

"I know!" Li Shimin nodded and said: "The heaven and the earth are round is a specific manifestation of the Yin and Yang doctrine, and it is also the evolution of the Taoist innate gossip. ”

Li Shimin still has some understanding of arriving at home, so compared to the stupid civilian, Li Shimin is obviously wiser.

"It seems that the imperial brother knows this, so I will explain it to you again if I don't have to save my brother!"

Li Yuanba nodded to Li Shimin with a smile and said, "Brother Huang." In fact, the statement that the sky is round is not accurate, do you see the sphere on the table, that is the world we live in, the vast heaven and earth! ”

"What do you say? This is the world we live in? Li Shimin's brows suddenly furrowed, and for a moment he couldn't believe Li Yuanba's words.

"Brother Huang, how can this heaven and earth be explained simply by the round heaven and the earth? Do you know where the end of heaven and earth is? Why does the sun and moon rise in the east and set in the west? ”

Li Yuanba can be regarded as understanding. Feelings: Li Shimin also knows nothing about the round sky, let alone let Li Shimin understand that they all live on the same sphere.

"You...... Yuanba. Are you going to become a monk? Li Shimin looked at Li Yuanba strangely, and continued: "You must not have this kind of thought, at least leave some more heirs for my royal family, and wait until fifty to become a monk!" ”

Li Yuanba was almost blown away by Li Shimin's words, what the hell is this? Why did you become a monk?

There is no way not to let Li Shimin have this kind of thought, whether it is the round sky or the end of heaven and earth. The sun rises and sets, all these are mysterious things, and only those Taoist monks who only know how to practice all day long will consider these issues.

"Then Brother Huang, do you know what Hun Tian said?" Li Yuanba said weakly to Li Shimin. I didn't have much hope.

"Nonsense, this is naturally known!" Li Shimin rolled his eyes and said: "In the Eastern Han Dynasty, there is a saying in "Zhang Heng's Armillary Notes" that the sky is like a chicken, the celestial body is round like a projectile, and the earth is like a chicken in the yellow...... So, you kid still doesn't read much! ”

Yes, it's terrible to be uneducated!

"Although Hun Tian said that he was not completely prepared, the statement that the earth was as round as a chicken is still not false...... Forget it, it's useless to say those! ”

Li Yuanba originally wanted to give Li Shimin a popular science, but when he thought about it later, it didn't make sense at all, so he hurried to get down to business:

"Anyway, the place where we live is indeed this sphere, and I have given this sphere a figurative name, which is called the earth!"

This kid is really stinky and shameless, and he directly plagiarized the name of the earth.

Li Yuanba fiddled with the earth with his hand, then pressed the globe with one hand, pointed to the strange patterns on it, and said: "Brother Huang, come and see, this sky blue place represents the sea, and those colorful shapes are land ......."

"Where is my Datang?" Li Shimin interjected.

Li Yuanba pointed to a large area of Asia with only the coastal area in the shape of a chicken, and said: "Here, this is the place where our Tang Dynasty is called the Eastern Empire by Persia and Tianzhu!" ”

"Here?"

Li Shimin frowned and looked at the largest piece of land in the middle that Li Yuanba pointed to, this one seemed to be a chicken, but the west and north sides were extremely broad, and said: "My Tang Dynasty only has such a small territory!" ”

Li Yuanba was a little speechless for a moment, looking at the vast Eurasian continent, only the Tang Empire, Persia, Tianzhu and Great Qin occupied such a vast territory, Li Shimin was still not satisfied.

It's really a lack of people's hearts!

Seeing Li Shimin's expression a little stunned, Li Yuanba hurriedly explained:

"Brother Huang, look at these places I specially marked, they are our Tang Dynasty, Persia, Tianzhu, and a Byzantium, that is, Daqin, in addition to these four major countries, the other continents are still in the era of Ru Mao drinking blood, which is equivalent to the form of more than 2,000 years before our Tang Dynasty!"

"And at present, Tianzhu and Persia are not our opponents of the Tang Dynasty, and the only thing that can be compared to us is the most vast Daqin in this territory!"

When he said this, Li Yuanba stretched out his hand and pointed to the Balkan Peninsula in southeastern Europe and said, "If we want to easily take down Great Qin, we must start planning now!" (To be continued.) )
