The night is already deep, but Yuechan has not yet felt the slightest sleep, Liu'er and Qi Niang next to her have slept very soundly, the weather has warmed up in the past few days, so that Liu Er and Qi Niang kick off the quilt from time to time, but Yuechan has taken the trouble to help them cover the quilt again. Pen ~ fun ~ pavilion www.biquge.info

Qi Niang originally had her own room, but today is a little special, because I saw that the light was still on in the study where Li Xiu lived, and the sound of two men quarreling came from time to time, which was extremely noisy in this quiet night, and the bedroom where Qi Niang lived was very close to the study, and she couldn't sleep at all, so she ran to them with the quilt in the second watch and slept together.

"That big man with a curly beard looks fierce, I hope I don't fight!" Yuechan looked at the study with the light not far away, and whispered to herself at the moment, the quarrel in the study became more and more intense, she was really worried that the vicious man would make a move, just by looking at the other party's figure, she knew that her master would definitely suffer.

"No, apart from Luzon, there are four large islands in the South Seas, not the three you said!" In the study, Li Xiu argued with a red face.

"Impossible, I have been to Nanyang at least a dozen times, and there are only three big islands in total, namely Borneo, Jinzhou and Java, where is the fourth big island?" The bearded guest on the opposite side also argued with a flushed face at this time.

When he was by the river before, Li Xiu asked the bearded man if he was a big pirate leader, and the bearded man told him very heroically that he not only occupied the southern part of Tsukushi Island, but also had a more powerful maritime power, monopolizing the trade between the Tang Dynasty and the Wa Kingdom, Silla and other countries, and he also had his own fleet in the Nanyang area, and he also had a lot of power, and he himself had been to the Nanyang several times and knew the Nanyang area very well.

Li Xiu didn't expect that the bearded guest would have such a strong maritime strength, and he could be called the pirate king of China's coastal waters, but the stronger the bearded guest, the more places he had visited, the happier he was, and immediately began to discuss with the bearded guest about the customs and customs of various places, starting from the Japanese kingdom, all the way south to Luzon, and then to the South Seas.

It was only at this time that the bearded man suddenly discovered that his nephew knew everything about overseas customs and customs, and even knew some things better than him, which made him even more surprised, and his gaze at Li Xiu became more and more incredible, but there were some things that he still couldn't accept, so quarrels broke out between the two from time to time, but many times he was proved wrong.

"Haha~, uncle, since you know Borneo, why don't you know that not far east of Borneo, there is a big island with a peculiar shape, although the area of this island is not as large as Borneo, but it is definitely larger than the Tsukushi Island where you live now!" Li Xiu laughed at this time and said that the big island he was talking about was actually the Sulawesi Island of the later generations, and the shape was like a distorted "ten", which was very peculiar.

"You...... How did you know that, boy, as if you had been there yourself? The bearded guest was also a little deflated at this time, he was still in the mood to argue with Li Xiu just now, but every time Li Xiu said it with a nose and eyes, he was not allowed to refute it at all, and this time he simply didn't bother to argue anymore.

"Hehe, don't care where I know, I don't dare to boast about anything else, I'm afraid no one knows better than me about the world we live in!" Li Xiu smiled again and said, the bearded guest is a person with eyes above the top, if you want to convince this kind of person, you must prove that you are better than him, although Li Xiu thinks that he is better than the bearded guest in many places, such as his handsome appearance, but unfortunately the bearded guest turns a blind eye to this, and he has to compare what knowledge with him?

"Boy, there must be a limit to big words, I don't believe you know everything!" When the bearded man heard Li Xiu's boastful words, he was aroused a little angry again, he always thought he was well-read, and he had personally traveled a lot of places, and his vision and knowledge were far beyond ordinary people, but he didn't dare to say that he knew the world.

"Hehe, if you don't believe it, uncle, then just say hello!" Li Xiu said confidently, in the era of the information explosion in later generations, Li Xiu was exposed to a wide range of knowledge, which was absolutely unimaginable to the ancients, so he was really not afraid that the bearded guest would have any problems that could stump him, even if he really didn't know, he could fool the other party by making up an explanation.

"Okay, don't you know everything, then tell me what is the end of the sea?" The bearded guest glared at the moment and said, in this era, as long as people who have been out of the sea, they will have such a question in their hearts, the sea is almost boundless in their eyes, as if they can never reach the end of the sea, but it is precisely because they can't reach it that people want to know what the end of the sea is, just like people in later generations want to know what the end of the universe is?

"Uncle, I can't answer this question of yours!" To the surprise of the bearded guest, Li Xiu shook his head very simply this time.

"Why, don't you know everything?" The bearded guest glanced at Li Xiu with some disdain at this time and said.

"Hehe, it's not that I don't know, but there is a problem with the question you asked, uncle, you are well-read, you must know what Hun Tian said, right?" Li Xiu smiled without being in a hurry.

"Hun Tian said that I naturally know, and from my sailing experience, the earth and the sea are indeed not flat, but if the earth is spherical, then the people under the ball are not going to fall?" The more intelligent the person, the easier it is to discover the fatal flaw of the Hun Tian Theory, even if the bearded man finds that the sea surface has a curvature, he still can't believe that the earth under his feet is spherical.

"Uncle don't have to doubt that the world we live in is indeed a sphere, as for why the people on the other side of the ball will not fall, this is because the ball under our feet has a kind of gravity, so that people and things on the surface of the sphere will not be separated, it can be called gravitation, this gravity is very complex, and we can discuss it again when we have time."

Li Xiu paused when he said this, and then introduced the earth again: "The ball we live in can be called the earth, and the interesting thing is that seventy percent of the earth's surface is ocean, so when the uncles sail on the sea, they will feel that the sea is boundless, in fact, it is indeed boundless, if the uncle recognizes a direction and keeps moving forward, in the end it will only return to the original point again!" ”

After listening to Li Xiu's description, the bearded man's eyes widened again, if what Li Xiu said was true, it would simply subvert his perception of the world, which made him a little unacceptable for a while.

After a long time, the bearded man came to his senses, turned to Li Xiu with a dull gaze and asked again: "Xiu'er, how big do you say our world is, if the earth under our feet is spherical, then what is it like beyond this earth?" ”

"From our point of view, this world is indeed outrageous, the land of Datang is not small, but it only accounts for a few tenths of the world's land area, in addition to the land, there is a more vast ocean, counting the land of Datang only accounts for about one percent of the world's surface, as for the appearance beyond the earth, if the uncle wants to know, the nephew can give you a general explanation!" Li Xiu also replied with a smile, I'm afraid he is the only one who can answer these questions of the bearded guest.

"You know even what's going on beyond Earth!" Hearing this, the bearded man exclaimed again in shock, "Is there anything else in this world that you don't know?" ”

"Didn't my nephew just say, there is really nothing in this world that I don't know!" Li Xiu smiled confidently again, as long as he could convince the bearded guest in terms of knowledge, it would be much easier to interact with him in the future, and at the same time, he would be able to gain his respect, and there would be no more incidents like today when he recklessly came to arrest him and return to the Li Mansion.

Hearing this, the bearded guest couldn't help but feel shocked, shook his head to regain a little calm, and then spoke again: "I thought I was a pedantic, but I didn't expect to meet my nephew today, only to find out that I was a frog at the bottom of the well, I wonder if my nephew can explain it to me, what are the places outside the Tang Dynasty and Nanyang?" ”

"Since my uncle wants to hear it, then my nephew will be ugly, speaking of which, our Datang can be called the most prosperous area in the world, you have also been there in Nanyang, where the natives are almost a group of barbarians, and they don't know what etiquette is, and go west along Jinzhou in Nanyang, and after passing through a narrow strait, they will enter the Tianzhu Sea......"

"I know this, where did many Persian maritime merchants come to our Datang!" Without waiting for Li Xiu to finish speaking, the bearded guest hurriedly spoke, he was really hit by Li Xiu, and now that he finally heard something he knew, he naturally wanted to show it.

"Yes, that strait we can call the Strait of Malacca, there is also a connection between the South Sea and the Tianzhu sea area of the traffic artery, after the Strait of Malacca to the west, you can reach the Tianzhu Continent, where is the origin of Buddhism, but now the Tianzhu Continent is divided into countless small countries, fighting with each other, more interesting is that Buddhism is not very popular there, only the southernmost Lion Country has always believed in Buddhism, and the Lion Country also enshrines a section of the Buddha's finger bone relics, the country is rich in gemstones......"

Li Xiu first talked about the South Asian subcontinent, then talked about the rise and fall of the Persian Empire and the rise of the ******, then talked about the African continent, and the ancient Egyptian civilization, and finally talked about the brilliance of the Mediterranean civilization, especially the rise and fall of the Roman Empire......

These are all things that the bearded guest has never heard of, at first he interjected to ask a few words, but then he listened to it as if he was fascinated, in vain he always thought that he had traveled from south to north and seen a lot, but he did not expect that there were so many places in this world that he had not yet reached, some places he had heard from the mouths of some Hu merchants, but it was far less detailed than Li Xiu's words.

After talking about the situation in Europe, Li Xiu finally crossed the Atlantic Ocean and began to talk about the situation in North and South America, and he also told the bearded guest at the end that a current-to-east could be hit from the island of Honshu of the Japanese country, and if it went well, he could reach the American continent in the rest of the month!
