Although there are no slaves on the Arab side, they are at war with other countries, anyway, the Tang Dynasty buys slaves, and those they capture do not surrender, and those who are not easy to deal with can naturally be sold.

War, in fact, can sometimes catalyze many things, because in times of war, the most precious things in peacetime are not so precious, such as life.

When even life is not so precious, not many people care about other things.

In particular, the war between these three countries has almost become like fire and water, and it is impossible to reconcile at all, in such a situation, as a Datang who trades with three countries at the same time, no matter who can offend.

Especially after Sassanid Persia learned that even the Western Turks had completely become a member of the Tang Dynasty, they were even more unlikely to offend.

In fact, although these trades are directly negotiated with the officials of the three countries, there are also directly negotiated among the people, after all, the nobles of the people will not think so much, as long as they can get the goods from the Tang Dynasty, it doesn't matter what they buy or sell.

Anyway, it's not them who sell it.

But the officials of these three countries need arrows, weapons, armor, food, spices and everything else from the Tang Dynasty.

And these materials, such as arrows and other things, can only be provided quickly and in large quantities by Datang, and Datang still provides iron arrows.

That's right, the iron arrows provided to them are naturally all iron arrowheads, and the steel arrows are only used by Datang himself, and it is impossible to sell them to the outside world.

The iron arrowheads sold to them are also graded, and the highest grade is naturally the iron arrowhead directly cast from pig iron, and then the arrowhead covered with a layer of iron sheet, etc.

Or just provide them with arrow shafts, and they install the arrows themselves, etc.

Whatever the method is, it consumes a lot of their resources.

In the past few years of trade, Datang has actually earned a lot of silver with them, such as Persia and other places where there was originally more silver, and the ratio of gold to silver was originally 1:10.

But because of the outflow of a large amount of silver, the current exchange ratio of gold and silver in Persia has also become the same as that of Datang.

Moreover, the gold settlement will only be settled according to Datang's own proportion, so they themselves had to exchange domestic gold for silver with ordinary people in China at the beginning.

In order to make this profit, Datang doesn't care, but after they have almost exchanged their domestic silver, they can only accept this price of gold.

Or you don't buy it.

And now Datang has finally begun to buy another thing, although it is a slave, but it is good news for them.

As for the price of the skin color grade given by Datang, they didn't care, although they knew that there were also blacks on the other side of the continent in Byzantium, but Datang didn't want it, and those blacks were primitive people, they couldn't understand the words, and they definitely didn't want to get Datang back.

Who cares about worthless things? Maybe one day when they want people to work, they will take them back to work, and it will always be better to use them than livestock, and it would be good to consume them as consumables.

It's just that Li Ke didn't expect that the slave trade between Datang and these countries would come much faster than he imagined, and in Li Ke's opinion, it would take until the 27th year of Datang before the first batch of slave trade was born.

It's just that the time is much faster than he imagined, and the first batch of slave trade was reached in less than ten days after the exchange between Datang and the three countries.

And the number of slaves in the first batch was as high as more than 5,000.

The first people to trade with them were the Arabs.

And this group of slaves came from the 4,000 Persian soldiers they had captured, and all the Persians in a Persian village they had just conquered.

In the past, they would have kept these people and gradually assimilated them into their own, but now they lack the funds, and they can exchange them for money, and they can vacate their land.

So these Arabs simply sold them for more logistical supplies, and it was more convenient, because after they stayed, they needed to send some soldiers to take care of them.

Now, just take care of it, and you don't have to take care of it.

If it is historical, because the war between Arabia and Persia was pushed all the way, many Persians surrendered directly, but now because of the intervention of the Tang Dynasty, Persia has received unprecedented support.

When the Arab momentum is curbed, the faith they propagate becomes less powerful.

Religion can brainwash people because they need to constantly tell them that believing in these gods can give them great power, can give them a better life, and allow them to defeat their enemies.

But when they are unable to defeat the enemy, or even defeated by the enemy, this belief is instantly shaken.

Li Ke couldn't know more about this, although religion is different from his brainwashing, but in fact, some aspects of the truth are the same, especially the nascent religion! Brainwashing in the early stage is very crucial.

Can Li Ke know about these? This is also the reason why Li Ke directly interrupted the momentum of the Arab offensive at any cost in the past few years.

Cutting off their momentum is not just a frustration for them, but directly digging out their foundation, and cutting off the soul on which they live, which is the most important thing.

After their momentum is cut off, their combat effectiveness will fall rapidly, the Arabs themselves do not think, but from the point of view of a third party, if the Arabs who quickly conquered the entire peninsula in the early stage had a combat strength of one hundred at that time.

After the Tang Dynasty curbed the momentum of their attack and annihilation of Persia, their combat strength was only fifty, and until now, this fifty has not recovered, and is even falling.

The reason why they don't feel it is because their opponents are even worse, after all, both Persia and Byzantium are countries that have been inherited for many years, and the internal system has long been rotten, all classes are rotten, and the army and the like are even more ineffective.

The enemy is even worse, and they, of course, do not perceive that their combat effectiveness has fallen.

But in Datang's assessment, their threat has dropped several notches.

Under such circumstances, the first Persians dressed in ragged clothes and boarded the ships of the Tang Dynasty.

It was under these circumstances that Joshua's family boarded the ship, and Joshua was desperate for his future, but he only wanted one thing, and that was for his daughter Celi to live.

Even if you become a slave, you just need to live. Before boarding the Datang ships, they had already been taught a lesson by the Arabs, and told them that they were going to Datang to be slaves, so that they would all be obedient!

They did not resist, the latter said that they had no right to resist, and it was better to go to that powerful country, Datang, than to stay in Arabia like a demon!

Just hope that their future master will be a little more merciful, Joshua kept praying in his heart.
