After a period of time, the two sides finally completed the transaction. The Centaurs were very satisfied with the iron armor provided by Zhenbei fort. Many people wear those armor directly on their bodies.

After the transaction was completed, Su Lun's team became stronger and 300 horses were mighty. Fortunately, these horses have been trained and only a few people can control these horses to keep up.

The time to go back was much faster than when I came back. Twenty carriages were basically empty. When I returned to Zhenbei fort, I arranged for these horses. Su Lun took a centaur longbow and was ready to try.

The Centaur long bow is longer than ordinary human bows and arrows, which is about one meter and five meters. In fact, this kind of bow and arrow is not suitable for cavalry. The bow body is too long and it is very inconvenient to ride on a horse. The length of human riding bow is rarely more than one meter, which is also the special body shape of centaur.

The range difference between ordinary riding bows and such longbows is close to one-third or more. Su Lun bought these Centaur longbows to make a walking bow. From this point, it can be seen that Centaur light cavalry can be said to abuse human light cavalry. They can fly kites to kill human cavalry, which is a racial advantage.

The Centaur long bow is made of purple shirt wood. The bow body is very smooth. Because it is a weapon used by centaurs, it takes a lot of effort to open the bow. People without professional training can't control it at all.

[Centaur long bow: hard bow. It uses purple shirt wood as the main material. It is an excellent Centaur long bow. It took a centaur craftsman three years to make it. It has much more toughness and range than ordinary bows and arrows. However, to use it, it requires good strength, long range and great power. Range + 1, armor piercing + 1, strength: 10]

When he came to the special shooting range, Su Lun stood about 120 meters away from the target, then stretched out his hand to pick up an arrow, stretched out his bow and took an arrow, aimed at the target and shot.

"Dong"

A sharp arrow fell into the bull's eye in an instant.

Next, Suellen didn't stop, grabbed the arrow inserted on the ground, and then shot at the target in front of him.

"Dong Dong!"

Five sharp arrows flew out in a row, with more than 100 bows and arrows. Su Lun's level of playing bows and arrows is very high. This kind of continuous arrow is not difficult for him. It took only a few seconds from the first arrow to the fifth arrow. The five sharp arrows hit the center of the target in just one breath.

Su Lun didn't stop. He grabbed the arrows and shot continuously. There were 30 arrows in a pot of arrows. Su Lun shot them all in half a minute. All the arrows on a row of distant targets were right at the center of the bull's-eye.

After some tests, these Centaur longbows have a quarter to a fifth longer effective range than the best walking bows used by humans, and a third longer range than riding bows.

The Centaur long bow can reach a distance of 330 meters at most, and the effective range can reach 200 meters. The best range is about 120 meters. Within this distance, the arrows fired have strong penetration.

Only sulun's iron tire bow can surpass the Centaur long bow in Zhenbei fort. The range of the long bow used by those war spirits is the same as that of the Centaur long bow.

This kind of bow and arrow can easily penetrate ordinary armor at a distance of 120 meters. Only the armor made of refined steel can resist this kind of bow and arrow.

Of course, the shortcomings of Centaur longbows are also obvious. It takes a lot of power to pull these longbows. Ordinary people can't use them at all. They can only master them after some professional training.

At present, the recruits of archers in the barracks can't use this kind of bow and arrow. They can only use this kind of bow and arrow when they upgrade the longbow. If they want to use it flexibly, they need to upgrade to elite longbow. But even so, the number of shots with this bow and arrow will be much lower.

It may be difficult for others to choose enough archers, but it just takes more time for Su Lun with plug-in.

The recruited refugees will become qualified recruits after training in the military camp for three to six months. In fact, if they were not weak before, their recruits' training would end in three months, and then they would patrol the territory with the barbarian guard. After several battles, they would soon be upgraded to Longbowman or elite Longbowman.

After understanding the power of these Centaur longbows, Su Lun had a clear understanding of the combat power of those centaurs. If Su Lun met a team of Centaur longbowmen when he just opened up his territory, 90% of his barbarian soldiers might be destroyed by the whole army.

These centaurs run faster than the barbarians, and the bows and arrows shoot accurately. As long as the barbarians are not given a chance to get close, the barbarians are a group of targets.

If there are 1000 elite longbowmen in sulun territory, even if there are ten times as many enemies to attack the city, they can destroy the enemy only by relying on these longbowmen.

After knowing the strength of the archers, sulun has decided to continue to expand the archers. Of course, if you want to build a large number of archers, you need to increase a sufficient population base. Although Zhenbei fort has found many ways to increase its population, so far the population is still less than 3000.

With the passage of time, Beidi wasteland has entered winter. When you get up in the morning, you can clearly see a piece of white frost on the roof. When I went out, my breath was already a white fog. The winter in Zhenbei fort was more than a month earlier than that in southern provinces.

After this month, it began to snow in Beidi wasteland. At that time, the roads will be closed by heavy snow, and the commercial roads in zhenbeibao and kart city will be interrupted. Therefore, if sulun wants to rapidly increase the population this year, there is only the last month left, and then there will be a three-month cold winter.

Not long ago, in the transaction of the Centaur tribe, Su Lun obtained 300 Jin of gold. These gold can be cast into jinnar. At least 30000 pieces can be cast. If the black heart is a little bit mixed with some other metals, it is not a problem to cast 10000 more. After all, even the jinnar officially cast by the king of Florence is also mixed with other metals.

He was going to let gene go to kart to buy slaves in large quantities while he had the last month left. In addition to buying serfs this time, sulun is also going to buy slaves with various skills.

Arrange a team of 20 war spirits and a team of barbarian warriors. Suellen asked boulder to follow Jean to kart city with 15000 jinnars.

After arranging the caravan, Su Lun began to think about the drow elves. Seeing that it was winter, which drow elves had not experienced the cold winter in the northern wilderness, he wanted to take over these drow elves. This was a good opportunity.
