For the sake of gold, people dare to do anything. Because there are also rewards for destroying the eagle's nest and falcon's nest, many people risk their lives and learn from Guo Jing to climb the cliff in order to destroy the eagle's nest and falcon's nest on the cliff. Destroying an Eagle's Nest or Falcon's Nest will reward you with 1 gold as long as you can bring back the corpse of the Eagle or Falcon, or an egg.

As a result, the falcons in many parts of the North Sea Kingdom were horrified to find that their nests on the cliffs were not safe, and they were extremely unsafe. In desperation, many falcons had to migrate away. However, their departure gave other birds a chance to breathe, and their numbers began to increase significantly.

Later, seeing that the number of many birds stealing grains began to overflow, Marin had to cancel the bounty so that the number of those birds was controlled to a certain extent.

However, this kind of reward, in a short period of time, did make the carrier pigeon a lot safer. Without the threat of falcons, carrier pigeons can naturally reach their destinations safely without losing numbers.

However, this method can only be used in the North Sea countries. Outside the North Sea Country, the Falcon troops under Marin's command could not operate smoothly in the territory of other countries. After all, other countries are not stupid and will not let a team of hunters on horseback and archery enter their borders to wreak havoc.

To this end, after discussing with his subordinates, Marin finally came up with a good way to buy Eagle Feathers (Falcon Feathers) and Eagle Eggs (Hayabusa Eggs). Send people to disguise themselves as merchants, infiltrate the territory of other countries on the carrier pigeon route, and buy eagle feathers and eggs from local hunters at high prices. With a heavy reward, these local hunters are sure to be happy to help.

Moreover, it doesn't take much to drive hunters from other countries to serve. Why? Because in foreign countries, the areas that need to be taken care of are actually some inaccessible mountainous areas on the middle of the road. As for the plains where there are many people, there are no falcons. In mountainous areas, the locals are often poor. You don't need to open a reward of 1 gold coin in the Beihai Kingdom, you only need to use a small silver coin of a pfennig to make the local poor mountain people take a risk.

In addition, it is too eye-catching to offer too high a reward in other countries. If you are targeted by the imperial court of the country, it will cause a lot of trouble. A reward or two of Finney is just right to attract the interest of the poor mountain dwellers, but not to the attention of the country's superiors.

Although those foreign mountain hunters are not as professional as the falcon troops of the North Sea Country, and they are not assisted by telescopes. But in the face of interests, their fanaticism is no less than that of the falcon troops, although it will not exterminate the nearby falcons, but it will definitely make the local falcons dare not approach. After all, the falcon is not a fool, and where it is chased and killed a few times, it will know where it is dangerous and will not come again.

You know, as a hunter, a minimum condition is to be more cunning than the prey. Otherwise, you will go hungry because you can't catch your prey. Just as a seasoned hunter is always more cunning than a foxwolf, the falcon, as a hunter, is naturally also cunning and knowledgeable. As long as you are hunted down a few times, if you don't die, you will know that you are powerful. Otherwise, he wouldn't be worthy of being a hunter.

In fact, in Western Europe, because of the high degree of development, there are not many falcons. And in some places, it is also possible to avoid the carrier pigeon by choosing another route. What really gave Marin a headache was actually Eastern Europe.

The Polish region is okay, the population density is still relatively high, and there are not too many falcons. However, when entering the Ukrainian steppes, because of the sparse local population, the range of the falcon is naturally larger, and it is easier to injure carrier pigeons.

The most troublesome is the Caucasus, where the mountains and forests are densely forested, and it is a natural hunting ground for falcons. Marin was there to offer bounties, and the most troublesome thing was the issue of currency.

After all, the small silver coins of Germany and France are not recognized in Eastern Europe, especially because they belong to the Orthodox and Green Church regions, and there is a gap between them and the Western European world, and it is inconvenient to communicate with them.

Fortunately, the Ukrainian region has begun exchanges and trade with the North Sea countries. And the Caucasus, then it has nothing to do with the North Sea State. But the region with the greatest loss of carrier pigeons happens to be in the Caucasus. Even in Greek mythology, there is a legend of the Caucasian eagle.

But this line had to be taken, because Marin needed to contact Persia quickly, so he had to take this line.

Before, it was possible to pass through the territory of the Mamluk dynasty and go through Syria. However, now that Syria is occupied by Turkey, it is difficult for carrier pigeons to take that line.

In addition, the Arabs of the Middle East have a tradition of falconry. The Arabian falcon was also very famous in later generations, seeing the pigeon flying in the air, the Arabs gave an order, and the falcon could easily intercept the carrier pigeon.

Therefore, in the Arabian Peninsula and Syria, it is a death zone for carrier pigeons, and it is extremely easy to intercept them.

In the Caucasus, although there are falcons, the locals do not have the habit of falconry. As long as you are willing to find a way, there will always be someone to help eliminate the local falcons.

And as long as you cross the Caucasus Mountains, it is the territory of the Persians. The Persians did not have the habit of the Arabs to falconry, and the carrier pigeons were much safer there.

Therefore, if Marin wants to open up the hollow communication route of Persia, the main obstacle is the falcon in the Caucasus Mountains. Of course, there are some obstacles in the Ukrainian steppes.

However, the obstacles in the Ukrainian steppes are not very large. After all, falcons actually prefer mountains and forests. Because, there are more birds in the mountains and forests, and the food source is more abundant.

Moreover, the Crimeans and Cossacks of the Ukrainian steppes, influenced by the Mongol culture of the Golden Horde, were often good at mounted archery. Even, there will be fierce people like "Condor Shooters".

At the same time, these guys, who are good at archery, love to drink. Although some people believe in the Green Religion, it is a rule not to drink alcohol. However, Marin was cunning and sold them liquor in the name of "drinks", and they still drank in the name of "drinks", tacitly acknowledging each other.

Therefore, in the Ukrainian steppes, Marin does not need to spend money, only needs to use rye two pot heads as a reward, and there are a large number of "eagle archers" willing to help hunt falcons along the way. That is, it is easier to clean up falcons in the Ukrainian steppes.

But there are some troubles in the Caucasus, which is less influenced by Mongolian culture, and the people there are also very early in the influence of the Green Religion. In addition to the fact that Armenians are staunch Christians, Azerbaijanis and Georgians are currently Green Christians. In later generations, most of the Georgians, deterred by hats, converted to Orthodox Christianity. But for now, it's still the territory of the Green Cult. If you want to use spirits to buy people there, you will probably be hacked to death......

Moreover, low-quality silver coins from Western Europe are also estimated to be in circulation in the Caucasus. However, according to the spies who had traveled to Persia by land, the locals were willing to accept the gold coins of Gulden along the way. After all, the purity of the European progress is high, and the Middle East also recognizes it.

In the end, Marin decided to let a group of his men take the gold coins and exchange them for silver and even copper coins in local circulation. Then, a bounty is offered to buy locals to help hunt falcons and dig up falcons' nests.

But at this time, Bard, a spy based in Persia, learned of Marin's concerns through carrier pigeons, and gave a plan - change the eagle halfway.

Bard believes that the falcons on the Ukrainian side are easy to clear, because there are not many falcons on that side. In addition, there are many Mongolian-style marksmen on the steppe, so it is easier to clean up. However, the Caucasus region is full of mountains and forests, and there are many falcons, so it is too expensive to get rid of them. Therefore, it is better to change the Falcon to deliver the message.

The falcon may not be as far as a carrier pigeon, but it is no problem to climb over the dangerous Caucasus mountains. As for the problem of the falcon's ferocity and untamability, Bard also gave a plan - hire a few Arab falconers and let them stay together for a while and touch several other falcons. When a few falconers get acquainted with the other falcons, they can be used to send messages. There were many Arabs in Baghdad under Persian rule, and there were many master falconers, which were easy to hire, and it didn't cost much money, and they could bring their own falcons to work......

Because the falcon itself is an aerial hunter, there is no other falcon to find fault. After all, it's not worth it. Although it is not as easy to use as a carrier pigeon, it is safe. As long as you don't encounter powerful hunters, there's nothing wrong with that. Moreover, the people of the Caucasus did not have as many "condor shooters" as the Mongols. The falcon climbed the Caucasus Mountain, and there was still no danger.

Falcon transmission is more difficult to convey over long distances, because falcons are not as obedient and easy to tame as carrier pigeons. However, it is still easy to take care of such a short and medium distance as flying over the Caucasus Mountains. Then, continue to transfer with carrier pigeons.

Moreover, the use of falcons to transmit messages also saves a lot of money on the cost of hunting falcons in the Caucasus......

Therefore, after much thought, Marin affirmed Bard's plan of "halfway through the falcon" and used the falcon to take charge of the most dangerous Caucasus route. For other safe routes, carrier pigeons are still used. And Bard was also rewarded by Marin for proposing the "Halfway Eagle" plan......
