Although Lao Luo always behaved like a traveler along the way, he was really not a traveler. Because if he hadn't behaved like a traveler, his war knife, sharpened in later generations, would have been discovered by the wise men of the Arabs long ago, and then he would have been surrounded and killed by the army, or chased by the army to the end of the world.

In the early morning, before the sun rose, Lao Luo was on the roof of the hotel, through the thin mist, hiding the reflection of the single-hole sniper scope, carefully observing the defenses of this so-called conquered city. It's rare to have such a good opportunity to peek into the ancient city defenses, how can you miss it?

What can only a few imaginary illustrations in textbooks illustrate in later generations? The offensive and defensive system of the battlefield in this era is completely different from that of later generations, this is an era when archers, heavy cavalry, light infantry, heavy infantry, trebuchets coexist, and there are even camel soldiers, elephant soldiers and other types of troops that are completely unknown.

All the battlefield parameters, all the logistical procedures, all have to be refamiliarized. Maybe the battlefield here is different from the homeland, and maybe there will never be a chance to attack this city, but everyone understands the truth that the stones of his mountain can attack jade, and there are always places that can be used for reference, such as the tallest minaret in the distance, which can be used as a signal tower for the commander of the city defender, such as the staggered arrow towers in the protrusions of the city walls, which can play the role of staggered fire points......

When the morning bell rang and the Arabs began to worship, Lao Luo stood on the roof of the house and played Tai Chi, which no one could understand here, so no one doubted his whereabouts before. Including Camille and Cui Eighteen, of course, this kind of slow boxing technique will not arouse the interest of others, but it is the best thing for Lao Luo to adjust his body and study Jingyuan's secret arts.

During the day, Camille went to report to his uncle, who was a minister of the dynasty, and it was said that he was preparing to go to school. Lao Luo didn't care about this, and took a few young boys to wander the streets of Cairo by himself.

The same Arab city, it is much bigger than Suez. The most different thing is that the industrial zoning here is much more reasonable, indicating that the Arabs have begun to pay attention to urban planning at this time, and the local people have different skins, iron tools, vegetables and fruits, cloth, grain, herbs, etc., and there is even a special artisan block.

Of course, in addition to the locals, there is also a special street for foreign or foreign merchants, which contains the gems of the merchants of the Delhi Sultanate, and their appearance is very similar to that of the Sikhs; There were Jews with small yarellas, who were generally responsible for the accounts of the merchants; There were also Greeks with golden or light brown hair, who generally sold Roman-style armor or grains such as wheat; Of course, there were also sellers of silk and porcelain, but Lao Luo did not see a single Chinese, only an Arab agent......

Passing through the neighborhood of imported goods (there should have been such a term, unfortunately I couldn't find it, so I had to use this instead) neighborhood, not far from the banks of the Nile, is the trading market for mules, horses, cattle and sheep, where all the shepherds or traders who sell cattle and sheep want a good harvest. In addition to these domestic animals, there are wild animals such as lions, leopards, and even elephants, and it is not known how they drove the huge African elephants from the grasslands to this desert city.

Bypassing the mule and horse market, which is full of the smell of cow and sheep dung, is the city of people that Lao Luo is more curious about, and it is also the place mentioned by the innkeeper Maher. Although he was already prepared in his heart, Lao Luo was still touched by many humans in cages, who were sadly sold as slaves, like ordinary animals.

Many of them came from defeated captives, while others were civilians taken captive by the army or slave traders in other countries or regions, and those of poor physique or quality were kept in cages for selection. Their destination was basically a ranch or farm of some Arab, where they worked until they died.

There are also higher-quality ones that are pulled to a distant platform, undressed, and then bought by the surrounding buyers. The so-called high quality is a strong man who can be trained as a warrior, or a beautiful woman who can be used as a concubine.

Of course, this was not of the highest quality, and it was said that the best slaves would be provided in closed places for the nobles, who were often not stingy with money, and the slave traders were often paid well.

The Arab slave trade should have been learned from the Romans, but it is ridiculous that later European and American countries always said that the Arab world was a barbaric and evil country, but they did not know that the root of barbarism was inherited from the northern shore of the Mediterranean. Moreover, Lao Luo seems that although the Arabs at this time were barbaric, they did not have the custom of teasing slaves to fight each other for fun like the Romans.

Roman civilization vs. Arab civilization, I don't know which one is more barbaric. Lao Luo can't tell this clearly, but these are the products of this era, he is not the savior of these races, although he looks at the slaves pitifully, he can't save them. Even if he could kill all the slave traders present, he could not change the slave trade of the Arabs, and he did not know how to arrange the fate of these slaves.

Naga, Mnaqi and Cui Shibalang were also very touched by these, and Lao Luo, who was silent, was also silent. In the Maasai tribe, there was no slave class, and when dealing with defeated captives, they only demanded equal compensation and redemption from the other party, or integrated into their own tribe. Although Shibalang also followed the education of the Tang Dynasty relics and also had slaves at home, he had never been to a place like a slave trading market.

The silent crowd walked slowly along the banks of the Nile back to the hotel, and no one in the middle wanted to speak.

During the afternoon exercise, Lao Luo found a place in the backyard of the hotel where no one was around, and erected many thick wooden stakes and stones of different weights. Then silently stared at Naga Munachi and Cui Shibalang practiced, Cui Shibachi is a thousand times to swing a knife, Munaqi is a thousand and five, Naga is to throw stones five hundred times, the three of them practiced very much, not to mention the serious Maasai people, Cui Shiba, a boy who wants to play slippery every time he exercises, has changed his appearance today, every time he swings a knife, he is fierce, and he doesn't know who he wants to cut in his heart.

When Mnaki and Choi cut the stakes to pieces, Camille returned.

"Teacher, I'm back." Camille's voice was visibly excited as he walked into the backyard driving range, "I'm going to study in Al-Azhar." ”

"Al-Azhar?" Lao Luo didn't think of this word for a while.

"Yes, the best school, Al-Azhar Mosque, the school supported by the Caliphate." Camille's face was excited.

"yes, congratulations!" Lao Luo is also happy for him, from a foolish boy to a promising young man now, this kid has changed well, "Don't disappoint your father." ”

"Yes, teacher, thank you for teaching during this time." Camille hesitated and continued, "My uncle has heard about you and wants to meet you. ”

"Your uncle? I don't know him, what do I see him doing? Lao Luo refused without thinking about it, "Besides, your side is over, and I will leave too." ”

"That's right, my father asked me to bring a letter with me to my uncle, probably he recommended you to my uncle." Camille explained, "Besides, it's nothing for you to see him, and I don't ask you to say yes or anything anyway." ”

"You know I hate trouble the most...... Lao Luo's face was a little heavy, "Your father, that old man, always likes to cause trouble to people." ”

"Don't dare to trouble you, it's really just to meet, and it's up to you to decide what you have." Where did Camille dare to say that his father was not, and he had to tactfully keep Lao Luo, who was afraid and respectful, "Besides, you see that I went to study in Al-Azhar, maybe I can introduce you to a few scholars, and I can accompany you to Kaihelen for a spin." ”

"Scholars? What scholars are there? Lao Luo was quite interested in this, "Okay, you can tell me, if there are really good characters, I will stay for a few more days." ”

"The one introduced by my uncle, who is said to have been invited by the caliphate, includes Ibn Yunus and Ibn al-Haitham, both of whom are well-known scholars...... "Hearing Lao Luo say that he was interested in scholars, Kamil quickly explained.

"What the hell does your uncle do, that he has the opportunity to get to know these people?"

"My uncle is the Caliph's Undersecretary of Commerce, his name is Naifel Abdul Rahaman Khaled, and he is in charge of Kahelen's commerce, and he is temporarily recruiting scholars for the Caliph." Camille explains.

"Oh, well, tell your uncle that you want to see me here." Lao Luo thought for a moment, let go and said, "You arrange the time, remember those scholars, I hope to meet them as soon as possible." ”

"Okay, teacher." Camille said helplessly, "I really hope the teacher can not leave." ”

"Really? Camille? Old Luo looked at Camille with a smile.

"I, I'm ......" Camille felt the tightness on his body, and quickly slipped out, still shouting, "I still have some business, I need to go out, teacher." ”

The few people watching on the side were laughing non-stop, although Camille was not Lao Luo's official entourage, but he respected Lao Jirohard's opinion, Lao Luo did not "educate" him, which made Camille have phobia.

"Is the mission complete?" Lao Luo stared at a few guys who laughed and said, "Don't hurry up and continue to practice......"

A few people hurriedly got busy, and only Eighteen Lang said more, "Third uncle, where are we going to leave here?" ”

"Where to go, I haven't figured it out yet, Rome? Constantinople? Baghdad ......"
