Although these mercenaries and guards are not as strong as the regular army, they are much stronger than ordinary people. Su Lun doesn't want to fight on the front line. As a result, these mercenaries and guards make trouble in the north city of the town.

Su Lun has never overestimated the integrity of mercenaries and caravan guards. In this era, it is very dangerous to do business in the wild, especially in the northern wilderness, in the city or within the city. These people are the same as normal businessmen, but they are the law of the jungle in the wilderness.

It's common for those businessmen, guards and mercenaries to rob other caravans directly. These people are caravans when they enter the city, and robbers when they leave the city. Unless they are directly caught, they can't be distinguished at all.

Moreover, there are many crazy things in sulun City, such as sugar secret recipe, rum brewing process, papermaking technology, etc. any of these technologies is worth thousands of gold. As long as you learn one that you can eat and drink all your life, it is impossible to even change your title.

From the first day after these people came to Zhenbei City, they wanted to steal these technologies. Far from it, Chris caught more than a dozen people who wanted to steal technologies last month, an average of one in two days. As for the final fate of these people, it was actually very good.

Alex told Suellen that the low-level Eagle Banshee wanted some materials. With a big hand, Suellen handed these people over to Alex and sent them to the eagle castle.

There are more than 3000 harpy banshees in the eagle castle. Except for the harpy man and the head of the harpy banshee, other harpy banshees can't get rid of their instinctive control. Those who dare to steal technology in the north town basically have two brushes, and their strength is fairly good. Many of them are Knight level.

This is good news for the eagle Banshee. 24 hours a day, these people are fed by the eagle Banshee. They have been working hard all the time. These people can be said to enjoy the feeling of a royal daughter 3000 directly rising to heaven.

Once the orcs attack the North Town, the city Lord's mansion will certainly transfer people. The protection will naturally be relaxed at that time. Su Lun doesn't think that those businessmen will miss such a good opportunity to resist the orc attack. They will definitely take advantage of this opportunity. Suellen never overestimated human nature.

The cheapest and most precious thing in the world is human nature, and the most untenable thing is human nature.

......

Blackstone fortress.

The war has been going on for three days. The orc army has sent a large number of servants to fight. These servants are used to consume human rolling logs, stones and bows and arrows. The high-intensity war makes the consumption of Blackstone fortress very large. The wall of Blackstone fortress, as a military important town, has been repaired quite well, and the orc army has not taken advantage of it.

On the fourth day of the war, before dawn, the orcs slowly approached the city wall with several huge siege instruments.

The siege tower is a simple building built with a wooden tower. Then the orc soldiers can enter from the bottom of the siege tower and step up the stairs step by step. Because there are wooden boards to protect them, they will not be hit by the enemy. The upper end of the stairs is the exit of the siege tower. This exit is flush with the height of the city wall. When you come out, you can immediately step on the city wall and start a white-edged war with the enemy.

This siege equipment is very rough, but the effect is not bad. These siege equipment were built by cutting down wood after the orcs came here. Although siege equipment is a sharp tool in engineering, their disadvantage is also obvious, that is, slow moving speed.

The siege instruments made by the orcs are rough and heavy due to technological problems. It is difficult for ordinary humans to push these siege instruments forward, but they are just good for the orcs.

In addition to these siege towers, the orcs also prepared some ladders and washing cars. These siege instruments, driven by the orc soldiers, kept approaching the wall.

The defenders and generals of Blackstone fortress looked dignified. After seeing these siege equipment approaching, they began to order the archers to launch rockets. Rockets are still very threatening to these siege equipment. After applying rocket oil, the ignition ability of rockets is still good. In particular, the siege equipment made by the orcs did not have many fire prevention measures.

After the bows and arrows hit the siege tower, the fire oil attached to the board and soon lit a flame. Although the orcs did not ignore it and pushed forward quickly, at the same time, the orc archers standing on the siege tower also began to shoot arrows. The archers of both sides began to compete. For a time, both sides suffered heavy casualties.

Then, under the cover of the archers, these siege instruments quickly approached the city wall. The fastest running vehicles were about to rush to the city gate. At this time, a fireball the size of a washbasin suddenly flew out of the city wall. The fireball dragged a long tail and flew directly to the car.

"Boom!"

An explosion came, and the whole car, together with a dozen Orc soldiers, was immediately surrounded by flames. Under this force, the wooden car was directly blown apart, and a dozen orcs were lit into a torch.

"Wizard! Wizard! We have wizards!" there was cheering on the city wall, and the morale of human soldiers soared in an instant.

On the city wall, a middle-aged man in a red robe waved his staff, and soon a fireball flew out. This time, the fireball flew directly to a tall siege tower. The siege tower, which was more than 20 meters high, could not be avoided and was hit by a fireball in an instant.

The siege tower, which had not been burned by a large number of rockets, exploded. The orc archers on the siege tower were blown out. The tall siege tower was directly cut in two from the middle. Many orcs below were directly hit by burning wood, and the flame shrouded the siege tower in an instant. The orc soldiers who did not run out were burned alive by the fire.

The wizard stopped fighting after he used several fireballs to destroy most of the siege equipment. The wizard is only a medium-level wizard. There are only a few wizards in Blackstone fortress. The wizards will not consume all their magic. They just shot more to boost morale.

Although many siege tower instruments were destroyed, the orcs soon pushed out some new siege instruments. This time, the Wizards did not continue to fight. A bed crossbow on the wall opened its bow string, and the toothy sound of pulling the bow string sounded. A soldier nearby put a spear on it and ignited it with fire oil.

"Collapse!"

With a buzzing sound, a three meter long spear flew out in an instant. The spear directly penetrated an orc, and then nailed it to the siege vehicle. The heavy siege vehicle shook back and forth several times, and the flame on the spear ignited the siege vehicle.

"Collapse!"

The bow strings on the city wall sounded continuously, and spears flew out one by one. The corpses where the spears passed were everywhere. The orc soldiers who were directly hit were a blood hole the size of a bowl, and some were directly dressed as sugar gourds.

However, the accuracy of the bed crossbow is limited and the firing speed is slow. There are still many siege instruments close to the city wall. Seeing this situation, the general guarding the city directly ordered a counter charge.

Five hundred Knights have been standing quietly behind the gate. All these knights are wearing iron armor and holding sharp blades. The five hundred Knights stand quietly behind the gate and wait for the gate to open.

An impassioned horn sounded, the gate of Blackstone fortress was slowly opened, and the knight regiment that had been ready immediately launched an assault. Five hundred Knights launched in an instant. The sound of horses' hoofs sounded like thunder on the battlefield. The knights in armor rushed out of the city gate in an instant, and then rushed directly to the orc's engineering equipment.

The orcs did not expect that humans would open the city gate and attack. He might as well be directly dispersed by human knights. The infantry were completely slaughtered when facing the heavy cavalry in the charge. Even the orcs are the same. Where the Knights pass, the orcs are cut down like mowing grass.

After only two charges, the orc forward was killed and scattered. Seeing the orc soldiers fleeing in confusion, these Knights did not continue to chase, but lit the oil they carried and threw it on the siege equipment. Dozens of siege equipment were soon ignited. After lighting these siege equipment, a dull horn sounded, All the Knights turned their horses back to the city. After the last Knight entered, the gate was closed again.

The battle is still not over. After losing a lot of siege equipment, the orcs did not choose to retreat, but allocated two or three thousand soldiers to take the ladder to attack the city again.

Count Louis, the keeper of Blackstone fortress, had a heavy face: "these damn orcs want to work hard to take us, and they are not afraid to have their teeth broken!"

The archers pulled the bowstring crazily. Many people's arms became extremely sore because they pulled the bow for a long time. Many archers' fingers had been cut by the bowstring, and the rain of arrows fell from the sky. These arrow rain did not scare the orcs. The orc soldiers held up one side of a rough wooden shield, many of which did not even peel off the bark, He attacked the city wall with arrow rain.

Despite the impact of casualties, a large number of orcs soon built a ladder on the wall. The orc soldiers behind rushed up as soon as they accelerated, climbed to the wall three times and two times, and then stabbed it with a gun by the waiting soldiers. Several soldiers nearby cut off the hook of the ladder, and then pushed it down, On the ladder, two Orc soldiers who had climbed halfway fell directly from the air.

After a few jumps, a tall Orc jumped up the city wall from the ladder, swept the huge axe in his hand, directly cut the soldiers who rushed up into two parts with human weapons, and then guarded the city wall to let more orcs climb up. After a while, five orcs came up here.

These orcs, led by the leading orc, defeated the surrounding human soldiers. Seeing this situation, several Knights immediately rushed up with people.
