The emperor of the Holy Roman Empire finally went back peacefully, and he also heard that the Germans were behind his back, so he simply did not admit that he was a German, and took his birthplace Italy as the motherland, and shifted the focus of the development of the empire from Germany to Italy, and stopped playing with them, so he had a personality!

Even more personal was the erudition of the emperor, who himself mastered seven languages: German, Italian, French, Latin, Greek, Hebrew and Arabic, and founded the University of Naples, inviting many Arabic teachers to teach students advanced Oriental knowledge. He was also a poet, published a collection of poems, had a deep knowledge of the law, loved the natural sciences, and is said to have personally conducted human experiments, which is why the church has a strong opinion of him.

But Hong Tao was not interested in this European emperor, he was interested in the fact that he happened to remember the year of the Sixth Crusade, and if this Karl could tell him what year he was captured, then according to the European calendar, he would be able to know how many years the year was in the Gregorian calendar. The calendar and year name of the Great Song Dynasty are useless to themselves, what year is the first year of Shaoding? He had no idea.

"Just 4 months ago! I followed the first Knights Hospitaller from the sea to the Levant, encountering a fleet of Arabs on the way. Carl reluctantly talked about his experience in Wheat City.

"It's 1228?" Hong Tao asked again.

"......" Karl didn't understand what Hong Tao meant, but nodded blankly. In his opinion, an Oriental who can speak German is already amazing, and how can such an amazing person still not know the year?

"Hehehe...... It's useless to know it! Alright, you grab the snacks, we're off to go! Remember, you're my captive until you pay the ransom, understand? It's dishonorable to run away, and you can't run away either! Do you know what kingdom you are in? At this time, Hong Tao saw Bo Xiaoer running from a distance with Bo Fu and Chen Mingen from the window, and pointed to the snacks on the table.

"I've sworn it...... This is the country of Seris! "Carl, this fool still doesn't understand why Hong Tao said this, will a knight break his oath after he takes it? It seemed impossible to him.

"Seris?" Hong Tao waved his hand at the three people below from the window, and then took Carl downstairs, this grandson was hungry, and the two plates of dim sum were gone......

"That's right! Seris, the land of silk! The mysterious Eastern Empire! Carl had a little food in his stomach, and his waist was straightened, he was about the same height as Hong Tao, with long arms and long legs, and he was dressed in a short dress like a shopkeeper, and his trouser legs and sleeves were only six or seven minutes long, which was very funny. But he didn't think it himself, and pointed to the merchants who were drinking tea and chatting on the first floor and explained it to Hong Tao.

"Interesting, Seris, is it Greek?" Hong Tao pondered, if the Latin silk is not said so, it is probably ancient Greek.

"Your wisdom is as vast as the Mediterranean, as Egyptian ......," Karl suddenly became literary, reciting poetry in a mouth of strange Latin.

"Stop! I'm not very good at Latin, so I'll speak German in the future! Hong Tao did not have the pursuit of being praised by others, he felt that once someone said this, he hated himself very much, waved his hand to interrupt Carl's chatter, nodded at the older shopkeeper in the counter, and saw that the other party was also smiling and making a gesture at himself, so he walked out with confidence, he was afraid that Luo Youde would forget to pay the bill.

"Grandpa, Fu Bo, this is a maritime merchant on my shipwreck, from the Great Qin Kingdom, after the shipwreck, he was captured as a ship slave, and I ransomed him back. He can't speak Chinese, I will teach him slowly in the future, let him live with us, his hometown is too far away, and there are no sea ships in the Great Song Dynasty to arrive. Moreover, the Great Qin State was at war with Persia, and once it fell into the hands of the Persians, he would have to be taken away as a slave. "As for the origin of this knight Karl, Hong Tao still has to make it up. It just so happens that there is a lack of a witness to the story of his shipwreck, so let him be it, anyway, few people in the Great Song Dynasty can understand ancient Latin and ancient German, and they can be blinded for a while.

"Tao Yanzi, will you fight the Jiao Shark? I heard Xiao Er say that you killed a lot and sold them for hundreds of dollars? Chen Mingen and Bo Fu stood in front of Zhenhai Tower, their faces full of anxiety, they didn't dare to enter here, it was useless to dare, they would be kicked out. But he was worried about Hong Tao's safety, and when he saw Hong Tao coming out, he didn't pay attention to the strange-looking Carl next to him, but pulled Hong Tao from head to waist, for fear that a piece of meat would be missing.

"Hey, hey, hey...... Grandpa, Fubo, let's get rich! Let's go back to the boat and say, the people here don't seem to like us very much. Hong Tao is not used to this feeling of being cared for, he doesn't need others to care, every time there is one more such person, there is more weight on his shoulders, and the more he worries when he tosses. Although this feeling is sometimes very moving, out of reason, he still instinctively downplays, avoids, and ignores.

Four barefoot Tan people, one of them still has a monk's head, plus a red-haired and dazzling Da Qin man, this combination is too weird, even a well-informed Song person like Luo Youde can't help but take a few more looks, not to mention these ordinary Song people and foreign merchants on the dock, even the sailor soldiers wearing green shoulders and holding iron rulers in their hands all stared at Hong Tao and them nervously, and watched them until they got on the boat.

These soldiers are different from the ordinary soldiers of the Great Song Dynasty, they are the sailors of the Song Dynasty who were specially sent to maintain the order of the port, not only in the port, but also the sea outside the port are under their control, and they can ask for help in big and small matters, and it is free. For example, if your boat breaks down, you can ask them to tow it back for you; In the event of a storm or pirates, they will also rescue in their area of responsibility. In addition to not helping you do business, as long as you arrive at the open port of the Great Song Dynasty, there are such sailor soldiers wearing green shoulders to protect the safety of ships from various countries, which is a bit of a coast guard.

Hong Tao didn't know which Emperor of the Great Song Dynasty and which ministers formulated this policy of opening up to the outside world, but he admired it very much. This policy not only has policies, but also implementation details, such as mobilizing non-governmental forces to supplement the deficiency of the state through the licensing of different goods, and the state exclusive purchase and sale of ten kinds of luxury goods, which are all very scientific macroeconomic regulation and control means. Even coastal rescue, supply stops, and language translation have been taken into account, and this Nima is a graduate of international trade, and he has also attended business school, and he even uses services to increase the competitiveness of the port.
