The construction of the city was thus settled, but the construction of the city could not begin until the design of Petus was released, and the construction of the town guard of the commander could be started earlier, and designing a building was not difficult for an architect like Pethius.

After the decree of Qindong was issued, the trade in the Pazar region began to flourish, the trading area was located on the south bank of the Maricha River, not far from the military camp of Qindong, and the merchants and travelers in the surrounding areas began to trade here, as long as they paid taxes, they could be safe, but in half a month, there were Roman merchants and Germanic merchants in the south with a large fleet of goods to trade, they brought salt, cloth, ironware, wheat, dried seafood, and even silk, tea and porcelain trafficked from the East.

When the Huns were not at war, they were very hospitable, they warmly entertained every guest who came from afar, after a hundred years, those who belonged to the peoples also learned the Huns' hospitable customs, they never plundered the caravan during the non-war period, on the territory of the Hun Empire, the caravans of all countries can pass freely, the Huns need these caravans to bring them much-needed materials, if there is no caravan to sell them food and clothing, many people and livestock may freeze to death in winter.

After the development of the Pazar trade area, it became famous in the Thrace region for a while, in the eyes of the vast majority of Romans and Germanic people, the Huns were very ferocious, these barbarians could not do business at all, let alone build cities and develop commerce, and now there are Hun commanders who set up border trade areas in the Pazar region, as long as they do business. It can be safe, and this kind of thing seems to many Eastern Romans and Germanic people to be absolutely the sun hitting the west.

But that's exactly what it is. As Pazar's border trade area grew famous, the merchants of the surrounding area traded here. The Xiongnu herders brought their cattle, sheep and furs here to sell, while the Eastern Roman merchants sold the goods to the Huns with the goods they needed.

As a result, some of the slave-turned-freedmen saw a huge business opportunity, and the Eastern Roman and Germanic merchants were unfamiliar with the situation when they first came here, so these freedmen borrowed money from Qin Dong to open shops to buy the Huns and other peoples' furs, cattle and sheep to sell to the Eastern Romans and Germans, and from the Romans to buy materials and sell them to the Huns and other peoples.

Although the border free trade zone was opened, Qin Dong still stipulated that there were some things that could not be sold to the Eastern Romans and Germans, that is, important strategic resources such as horses, although there was no shortage of war horses in the Eastern and Western Roman Empires. They have their own horses, and they can also buy them from the Persian Empire, but their war horses are different from the war horses of the Huns, because the Hun horses have lived in the cold north for a long time, although the size is not comparable to the Arabian horses, but in terms of endurance is not comparable to the Arab horses, and the Hun horses are not picky eaters, they can survive in most environments, and are suitable for long-distance running. This is also one reason why the Hun cavalry is so strong.

Qin Dong stipulated that horses could be bought and sold freely within the territory, but could not be transported out of the border, and smuggling out of the border was smuggling, and if caught, heavy fines were imposed. At the same time, Qin Dong also made regulations for the army, no weapons and bows and arrows in the army can be sold, even if they are used, they must be taken back and handed over to the logistics department for disposal. Any soldier who lost his weapon or bow and arrow was to be held accountable.

For the border free trade zone, Qindong is not to let it be truly free. Nothing, he sent a special official to manage the trade zone. There were also cavalry units to maintain order, to deal with emergencies, and the officials in charge of the markets were responsible for mediating disputes between merchants, and stipulated that prices must be stable and kept within a boundary, and that unscrupulous Eastern Roman and Germanic merchants were never allowed to deliberately lower prices to buy cattle, sheep and skins from the Xiongnu herdsmen.

Qin Dong understood that it was not much money to sell raw materials, and that in order to make money, those raw materials must be deeply processed, and the raw materials became semi-finished products and finished products after deep processing, and the price was many times higher, so Qin Dong asked those herdsmen to teach them to tann leather, teach them to spin wool thread, and weave wool thread into finished products such as carpets, blankets, wool felt, scarves, wool sweaters, etc., and also taught them to use plant juice to dye textiles, so that the finished wool weaving products have a variety of colors and patterns, the grade will be improved, and the value will be multiplied.

Eastern Roman and Germanic merchants were very fond of the wool weaving goods, which were warm, colourful, and varied, and would sell well if they were shipped back to Constantinople, so they bought wool textiles in large quantities.

Qin Dong also asked the herdsmen to make cheese into dried cheese, which can be eaten as a snack or made into tea, and the excess milk or goat's milk that cannot be drunk every day can be made into cheese for sale, which is not easy to spoil, easy to preserve, and suitable for long-distance transportation. Since there was no preservative and preservation technology in this era, things like beef jerky and lamb jerky could not be made.

In order to prevent the outflow of strategic resources or smuggling them by unscrupulous merchants, Qin Dong set up a special point for the army to purchase horses, cowhides, horns, tendons, horns and other materials sold by herdsmen for making bows and arrows.

On this day, Qin Dong wore ordinary herdsmen's clothes to check the market situation in the business area, and Batu and Liu San followed not far behind him with a few guards.

Everyone was strolling around the crowded trade area, Liu San suddenly stopped and didn't leave, he looked at an Eastern Roman vendor on an item and was fascinated, and then hurriedly walked over and picked up an oriental ancient jade and looked at it, then slowly put it back in its place, and looked at a few other things before turning his head and saying to Batu: "Hurry up and ask the young master to come over!" ”

Batu didn't understand what was going on, but he still asked a guard to go to the front to invite Qin Dong over, Qin Dong quickly walked over under the guidance of the guard, and Liu Sancai whispered in Qin Dong's ear: "Young master, look at the fast jade pendant on this stall, is it a pair with the one on your neck?" ”

After listening to Liu San's words, Qin Dong noticed that there was indeed a jade pendant on the stall, squatted down and picked it up to take a look, sure enough, it was a pair of jade pendants around his neck, his face changed slightly, but he said to Liu San quietly: "Give money, ask him where this jade pendant came from, and then tell me after asking clearly!" ”

"Yes, young master!"

After returning to his big tent, Qin Dong put the jade pendant bought from the stall on the table, and took off a jade pendant from his neck, together it was a pair of dragon and phoenix jade pendants, Qin Dong hung a dragon pendant around his neck, and the one he bought was a phoenix pendant, the phoenix pendant should be on Qin Dong's mother Caroline at this time, but she appeared here at this time, something must have happened in the middle.

Qin Dong had crossed over from the afterlife, and he had no feelings for the relatives of the original owner of this body, but the blood in his body was destined to find his mother Caroline and bring her to live in Pazar.

Qin Dong was deeply worried about Caroline, the mother of the original owner of this body, no matter what, the blood connection made him unable to leave Caroline alone, and the matter of going to Constantinople to take Caroline over must be carried out as much as possible.

It didn't take long for Liu San to come back, only to see that his face was a little ugly, Qin Dong saw Liu San's face and knew that something was likely to be wrong, he asked, "Uncle Liu, how is it, have you asked clearly?" ”

"Asked, but the Eastern Romans don't know what happened, this phoenix pendant was received by him from a ruffian, so in this way, the master mother either had to sell the jade pendant because of financial constraints, or it was stolen or robbed!"

After hearing this, Qin Dong stood up and said, "Liu San, go and prepare, in ten days, we will disguise ourselves as a caravan and set off for Constantinople, remember, this matter must be kept secret, except for a few major officers and officials, no one else can know!" ”

Liu San hurriedly said: "Young Master, now that you have a heavy responsibility, it is not appropriate to go far away, just let the old slave take a few people!" ”

Qin Dong shook his head and said, "No, I am not only going to pick up my mother this time, but also have other very important things to do!" ”

"Okay then, the old slave will do it!" (To be continued......)
