The question soon became clear that these Arabs were not pure foreign merchants, but permanent residents with green cards of the Great Song Dynasty. According to Hou, there were a large number of Arab merchants living in Guangzhou and Quanzhou, who bought real estate here, even married wives and had children, and lived the same life as the people of the Great Song Dynasty. The Great Song Dynasty government also opened up residential areas for them in these two cities, so that they could live with their own people, so as not to have friction with local residents because of different living habits.

As for why the Arabs are treated so favorably, there is only one answer, they pay more taxes! These Arabs had their own merchant ships, which came from their homeland once a year, loaded with spices, ivory, and jewelry. These things were not available in the Great Song Dynasty, so they would naturally be sold for a good price, and then they would load the porcelain, silk and tea of the Great Song Dynasty, return to Arabia, and become a wealthy man with thousands of dollars in their pockets. So much so that the emperor of the Song Dynasty knew about their existence, and personally issued an edict, persuading these Arabs not to live a small life behind closed doors in Guangzhou and Quanzhou, but to go back to their hometowns to see.

Why was the emperor of the Southern Song Dynasty so enthusiastic about the life of the Arabs? Because these Arabs didn't want to go back when they came to the Great Song Dynasty, they stayed in the courtyard they bought before the money was spent. If they don't run business, the tax revenue of the Great Song Dynasty will be less, which shows that the Great Song Dynasty is a very thorough commercial society, and even the emperor has to stand up and speak for a little bit of taxation. This is impossible for any other dynasty, and those who stand up are either traitors or executioners, either offering foreigners as ancestors or driving foreigners like beasts, but no one thinks about how to do business with them and let them contribute to the country.

These Arabs all have one surname, which is Pu! And this surname also appeared from the Song Dynasty and was specifically used for Arabs, so all those with the surname Pu, especially in Liangguang and Fujian, are basically descendants of Arabs who settled in Guangzhou and Quanzhou in the Song Dynasty. But why did the Arabs have the surname Pu in the Song Dynasty? Because most of their surnames are named after Abdullah, Cantonese people hear Abdullah...... Oh, so your surname is Pu!

After eating, drinking, and seeing enough, it was already midnight, and Hong Tao refused Luo Youde's enthusiasm and insisted on returning to the ship to spend the night. On the one hand, because Bo Zhu was still on the boat with a few children, he was not very relieved, and on the other hand, he had something in his heart, and he didn't have the heart to have a long talk with Luo Youde. According to the small talk with Hou Fang and that Yan Wei tonight, Hong Tao had a basic judgment in his heart about the situation in the north, that is, the Jin State would not last long, and maybe the Inner Mongolians would launch an attack on the Southern Song Dynasty in five years. But on his own side, let alone helping the Southern Song Dynasty court to stop the Mongols, he didn't even have a serious warship. Forced by the situation, Hong Tao didn't dare to develop slowly, he had to think about how to speed up!

In fact, Hong Tao is a history illiterate, he is in a hurry, if he can be given a junior high school history textbook now, he will be able to develop step by step for another 20 years. Because in history, after the Mongols destroyed the Jin State, they did immediately launch an attack on the Southern Song Dynasty, but they fought back and forth for decades, but they did not break through the defense of the Southern Song Dynasty army, and both sides lost and won. It wasn't until Kublai Khan began to make a breakthrough from Xiangfan and entered the Yangtze River basin from the Han River that he really broke through the defense of the Southern Song Dynasty, and it took less than 6 years to sweep the Southern Song Dynasty away.

The problem is that there is no if, Hong Tao thought that he was about to be too late, and his mind was full of thoughts that the Mongols were going south, and directly set this deadline between five and ten years. After returning to the ship, let everyone go to sleep, and he was on duty himself. It's not that he sympathizes with his subordinates, but he can't sleep at all, his mind is a mess, and he has to find someone to talk to and clean up. Who to look for? Carl, the unlucky bastard, has been honorably chosen again!

"Lao Ka, you and I are considered to have fate, and the word fate means God's will. It's your God, my fate that made us meet by chance, and I'm going to send you back to China. However, now that something has gone wrong, I have to change my previous plan for a while, and I am afraid that the time for you to go home will be delayed, can you understand? I didn't break my promise, but I was in big trouble. Hong Tao leaned on the helm platform, and wanted to have a cigar to smoke, even if it was a cannon, but unfortunately Hong Tao had not found the tobacco yet, as for whether it came from South America, or whether it was originally in Asia, who knows.

"My lord, can you tell me the specific reason?" As soon as Carl heard that his return to China would be postponed, the light in his eyes instantly dimmed.

"In the north of the Great Song Dynasty, there is a country called Mongolia, which has just emerged in recent years and has very strong combat effectiveness. According to my estimates, it will soon launch an attack on the Southern Song Dynasty, and the Southern Song Dynasty will definitely not be able to defeat it, and the result will be that the Southern Song Dynasty will be destroyed, and my ancestors' hometown will be occupied by barbarians. I don't want this to happen, I want to help the Great Song defend against the invaders from the north, so I may not have time to take you on a long voyage in the past few years. You must know that it will take about a year to travel from here to your hometown, and if the northern invaders defeat the Great Song army during the time I am away, when I come back, it will be too late to help the Great Song army defend against the invaders, so I want to postpone going to your hometown for a few years. "Hong Tao is not so much discussing with Carl, but trying to find someone to talk to, no one else is suitable, only Carl is the most reliable, he knows what is in vain, even if a Great Qin person goes to the Great Song Dynasty Mansion to denounce himself, no one will believe it.

"Like the Vikings?" Carl's comprehension is quite strong, and he found a suitable example in an instant.

"Well, almost, but there are a lot more than the Vikings, hundreds of times!" Hong Tao actually didn't know how many Vikings were when they entered Western Europe, so he just said it casually.

"A hundredfold! Lord, how are you going to defend against them? Carlton panicked, it seems that the Vikings are still very powerful in the eyes of Europeans.

"I don't have a perfect plan for how to defend myself at the moment, but I'm always going to try. You know, Karl, the Vikings here can only ride horses and can't row, and in the north of the Great Song Dynasty, there are many big rivers that can stop their progress, do you think if I build some particularly powerful warships to block the crossings of these big rivers, can it work? "Hong Tao is also blind to ancient wars, he has neither experienced nor studied, he has no practice to practice, he wants theory without theory, he can only think nonsense.

"How long are those big rivers? How wide? What about the speed of the water? Carl seems to be much more reliable than Hong Tao, and at this time the quality of a professional soldier is revealed, and he at least knows what to care about.

"Uh...... It is thousands of kilometers long, or longer. Width, about a kilometer, or more. The current should not be very fast, and we can't cross the river where the current is too fast. When asked a specific question, Hong Tao still didn't have an accurate score, where did he know what the situation was in the Yangtze River and Huai River in the Song Dynasty, so he could only say it blindly.

"Thousands of kilometers!" Carl had already learned the concepts of meters and kilometers from Hong Tao, but he was not familiar with them yet, and he had to convert them to Rome, which he was familiar with, in order to have a vague concept.

"That's going to take many, many ships to defend, I'm afraid it's hard to ......" Cal began to shake his head after figuring out the unit of length, obviously disagreeing with Hong Tao's defense.

"Well, I admit, I'm not a qualified soldier and I'm not good at fighting. If you were me, how would you defend against the Mongols? Hong Tao is still very humble in an area that he is not familiar with, and as long as he thinks that there is someone who may know more than him, he can listen patiently.

"I've never been in this situation either, to be precise, I've only participated in this crusade...... But my lord, since you know the Vikings, why not do what they do? All you need is a fleet, then take your warriors, choose any port of the opponent to land, and when the enemy reinforcements arrive, you can hold it, and if you can't hold it, you can get on the ship and go to the next place, the sea voyage is always faster than the land march. The coasts of England and the Franks, where many places were once captured by the Vikings, were such tactics. Carl didn't brag to Hong Tao about how he was a hundred battle generals, and it was precisely because of this that Hong Tao took the next paragraph to him to heart.

"Landing battle! It's kind of interesting! Hong Tao felt that the method that Carl said was a bit high-end and high-grade, and it also met his own conditions. First of all, it does not need a large fleet, as long as it can control the sea supremacy in the landing area. Secondly, the landing battle is to take the initiative to attack, without passive defense, which is very in line with Hong Tao's character, he does not like to float on the river every day, always wondering where the Mongols want to cross the river. Now we can hit you wherever we want, we can fight as much as we want, and we can fight whenever we want, how energetic! In the end, Hong Tao likes to save trouble, not trouble.
