"Jean, don't be under pressure, in all fairness, aren't these pieces of jewelry exquisite?" said Suren as he picked up a piece of jewelry and said to Jean.

"Yes, these pieces of jewelry are some of the finest I've ever seen. Jean nodded.

"Isn't that it, we need to give him a reasonable value for this kind of fine jewelry. Su Lun said.

"As for the jewelry made by real elves, how many people have seen it now?" Su Lun picked up the pair of bracelets shaped like immortal birds and said, "Since few people have seen them, what are you worried about?"

"Then you say that it was found in the ruins, and then you can guide it a little, and with the beauty of these jewels, those people will naturally believe it. ”

Why did Su Lun have to pull these jewels on the elves? It's very simple, because of the price, in the human realm, the nobles are very sought after for the things left by the elves, so as long as the things related to the elves have to pay at least several times.

The second wife of his cheap father brought a necklace from her mother's house, which was said to have been made by an elf, and it was said to have been prepared for her by her father, the Marquis of Osborne. Su Lun had seen it a few times at the time, and to be honest, the necklace was indeed beautifully made, but it was just like the jewelry in his hand.

This is also the reason why he dares to pretend to be the jewelry made by the elves, the elves have returned to the elven forest for hundreds of thousands of years, and there can be a few pieces of jewelry made by the elves, so Su Lun is not worried that this will be debunked at all.

Jean really deserves to be a business-minded guy, and after being reminded by Su Lun, he immediately prepared a set of rhetoric, and then after Su Lun made up the differences, a story was made up by him.

Originally, the price of these beautifully crafted jewelry pieces was more than 1,000 gold narls at most, but now with the blessing of the elf background, they can be sold for at least 5,000 gold narls.

Five thousand kinnars, all purchased into grain, enough to support his territory through the winter.

After discussing with Jean, Suren asked him to go back and prepare, and the caravan set off in the next few days, this time the caravan's escort Suren was going to let the new barbarians go half, and Johnson also brought half of them, in order to let these new barbarians grow up as soon as possible after a few battles.

With Johnson and these veterans here, Suren doesn't have to worry about those newcomers suffering losses. The goblins, kobolds, and gnolls encountered along the way almost upgraded after a few back and forth.

With the matter in order, Suren began to deal with another crisis facing the realm.

Ice pterosaurs generally do not attack humans, because compared to the prey of bison, giant horned deer, and impala in the wasteland, the risk of attacking humans is higher, so he is safe here for the time being, but after winter, the animal activity in the wasteland is scarce, and the ice pterosaur is likely to attack humans after there is not enough prey.

Suren couldn't pin the security of his territory on whether the Ice Pterodactyl would attack, so the best thing to do was to make a ballista.

Surren had already made a ballista, was very familiar with the structure of the ballista, and more importantly, he later gained mechanical control, gained a lot of mechanical knowledge, and had some ways to improve the ballista.

There are also ballistas in this world, the names are bed crossbows, giant ballistas and other different names, in fact, they are all the same thing, the structure of the ballista is complex, and the operation is also very inconvenient, a ballista needs eight to ten people to complete the operation.

The range of the ballista can reach up to a kilometer, but this distance is actually not powerful for a long time, let alone any accuracy, in fact, the effective range of the ballista is between four hundred and six hundred. Of course, accuracy is difficult to guarantee.

This kind of ballista is powerful, using a two-meter-long javelin as a weapon, and can shoot into rammed earth walls within 400 meters, even if it is a masonry wall, it can be more than a foot deep, even if the ice pterodactyl is shot by this kind of ballista. However, although this weapon is powerful, it also has many disadvantages.

First of all, the winding speed is slow, and when winding, it requires several strong men with big shoulders and round waists to work together, and secondly, the accuracy is low, basically after more than 200 meters, the crossbow arrow has no accurate head. Thirdly, it was difficult to carry, the ballista was heavy, and it was generally fixed to the city wall.

Fourth, it is difficult to maintain, the bowstring used in the ballista is specially made, and it is best to be the tendon of some high-level warcraft, but this tendon is too little, and the cost is expensive, so most of the ballista uses specially processed cow tendon, which is wound with the cow tendon into one, and at the same time adds silk steel wire and other mixed winding, the bowstring made in this way has a short service life, and basically needs to replace the bowstring after six or seven uses.

In addition, there are some other shortcomings, although these defects have not been solved after Sulun's transformation, but they have also been improved a lot. The most obvious of these is the increased winding speed, which uses the principle of pulley block and lever, and the ballista is much easier to operate.

At the same time, the ballista uses stainless steel as parts, which makes maintenance easier and the service life is increased, of course, not all of them are good, so the weight of the ballista is increased again.

Suren divided the design of the ballista into various parts, then asked the blacksmith to make them according to the drawings, and finally he assembled all the parts himself, so that the process of making the ballista was still known to him alone. The bowstring of the ballista uses the main tendon of the Raging Wind Demon Tiger.

After the more than 20-meter-long main rib was specially processed, a total of sixteen bowstrings were made, and this time Suren was going to make eight ballistas, eight of which were directly loaded, and the rest were kept for backup.

Eight ballistae were placed on all sides of the town, and Suren had built eight high platforms in the city to install them.

The construction of the territory was still in progress, and the first iron ore mined in the mines was transported to the port by water, although the boat was slow and required the boatman to paddle, but even then it was much faster than land transportation.

What is the situation of the road in the wilderness, Su Lun knows it clearly. In comparison, the ore transported by ships at one time is more than ten times that of horse-drawn wagons.

Once the ship docks, the goblin slaves who have been waiting here for a long time begin to load and unload the ore, which is then sent to the blast furnace of the blacksmith's shop. At most, the day after tomorrow, the first iron tools produced by the mine's iron ore will be baked.
