The other side of the Black Rock Canyon.

In a col about two kilometers from Blackstone Fortress.

The rocks in the col have been cleared, and the mountain wind blows coldly, and the whining sound is incessant. Three bonfires were also lit in the clearing, and dozens of burly orcs sat scattered next to the bonfires, sitting silently on the ground, chewing some food in their mouths, and looking up at the sky from time to time.

There was a sudden sound of wings flapping in the dark sky, and then a gust of wind hung up, and several bonfires around were blown into flickering light, and several creatures with bodies of more than three meters and wings spread about five meters fell from the sky, and then the firelight could clearly see their hideous and ugly faces, officially bipedal wyverns.

Several orcs flipped off the two-legged wyvern, and the two-legged wyvern flew into the sky once more, heading towards the orc camp. The other orcs nodded at the newcomers, and silence soon returned to the humble camp.

These orcs entered the Nafir Mountains when the orcs began to attack the Blackstone Castle, and after many hardships and heavy casualties in the mountains, these orcs finally crossed the Nafir Mountains. Among them, those who died in the mouths of various demonic beasts, those who died by mistake, and those who fell into the abyss, the original team of more than 300 people, in the end, only a few dozen people remained.

However, they also succeeded in completing their mission, finding a hidden col behind the Blackstone Fortress and establishing this humble camp.

After returning to the orc tribe, the two-legged wyvern once again took off with more than thirty orc warriors, and the same orc shaman blessed them with flying skills again, and the two-legged wyvern once again flew towards the back of the Blackstone Fortress.

The two-legged wyvern continuously transported the orcs to the rear of the fortress, and although it could only transport about thirty people at a time, it added up to a lot. The orc warrior led by him looked up at the night sky, it was pitch black and there was no light, this kind of weather was the best camouflage for the bipedal wyvern.

For this plan, the tribe has taken all the bipedal wyverns that have been domesticated over the years, blessed them with spells, and let them take on the transportation. According to the plan, they can transport almost five hundred orc warriors before the operation tonight.

More than 500 of the most elite orc warriors may not be very good on large battlefields, but they are very good for sneak attacks as death squads.

Wait for the humans, soon the army of orcs will return to that fertile land again, relying on the help of the elves and dwarves, those emaciated humans took the land from us, and now we will take back all the land left to us by our ancestors!

The orc leader took a sip of his wine and handed the sac to the other orc warriors, the night wind howled, adding a few sticks of wood to the campfire, and the orcs waited silently for the Wyvern to bring in more soldiers.

Orcs are born with dark vision, although they are only less than ten meters away, but with the faint bonfire, they can already see their surroundings clearly. Faintly in the night, hundreds of orcs have already arrived.

These orcs are silently chewing dry food, these dry food is coarse and unpalatable, it is the unique cold wheat of the Northland, this is also one of the few foods in the orc tribe, for tonight's battle, the orc tribe can be said to be doing their best.

In fact, since last winter, the orcs have been in short supply of food, and they have finally survived the cold winter, but this year, the appearance of the elemental tide has caused a large number of beasts to mutate, and the original demonic beasts have also become very active, which has made it even more difficult for the orcs, who are already living a difficult life.

Röm didn't know what elemental tides meant, but he did know that the white dragons on the ice sheets were more active, and they had to migrate south in order to survive.

As one of the high-ranking members of the orc tribe, it was well aware of how important this war was to their tribe, and as the key to victory, tonight's surprise attack played a decisive role.

They can't fail!

There is no chance of failure once!

Losing their fertile land, the orcs had a very difficult life, there was not enough food, many tribesmen froze to death every winter, and every heavy snow was a test of life and death. Cold and hunger have been with Rohm since he was born, and this time he wants to make it impossible for all his people to endure hunger and cold!

The human kingdom is about to harvest food at this time, as long as they break through this blackstone fortress, there will be abundant farmland everywhere, and countless grains are waiting for them to harvest.

After looking at a timekeeping tool given to him by the great shaman, the time was already half past two in the morning, calculating the time, the last group of orcs should almost arrive, according to the plan, they would attack at three o'clock in the morning, one after the other.

The Blackstone Fortress was built to defend against orcs, and although it has two walls, the one to the south is not high, after all, the rear is human territory.

Soon there was a sound of wings flapping, and the last group of orc warriors arrived, and there were already nearly six hundred elite orc warriors in this small col in front of them.

The orc officer's scarlet eyes glanced around, then he picked up his weapon and walked towards the outside of the mountain pass, and behind him, nearly six hundred orc elite soldiers silently followed.

......

Gavin has not slept very well at night, he always feels that the situation seems to be wrong, but he can't find any problems, which makes him a little irritable, the battle during the day makes his body very tired, in order to cope with tomorrow's battle, he must ensure enough sleep, although he has some doubts in his heart, but Gavin still forces himself to sleep, although it is not very comfortable in armor, but he has long been used to it.

Just as he was sleeping soundly, the alarm bell rang several times.

Gavin immediately got up, and then rushed out with the guards who were also awakened, and as soon as he came outside, the entire fortress was filled with killing shouts, and the fire was dark in the night, and it was completely impossible to see how many enemies there were. Seeing this, Gavin immediately began to gather the soldiers.

"Listen to the soldiers of the Thorns! I'm Gavin, and all the soldiers of the Thorns are back at once!"

Gavin shouted, and soon a large number of soldiers gathered around him.

"Don't panic everyone, light the torches, the number of enemies is not large, the fortress has not been breached, these orcs are a small force running from the Nafael Mountains!"

The guards around Gavin kept shouting, and more and more soldiers stopped running around like headless flies.

But his behavior was so conspicuous in the chaos that the orcs noticed it when Gavin's side gathered nearly a thousand people.

"Head, there's a big fish there!Looks like he's supposed to be the human commander, can't let him keep gathering his troops!" said an orc, pointing to Gavin, who was shouting loudly in the distance.

"Call your man, come with me, I'm going to kill that human!" Rom's eyes flashed with a fierce light.

As he spoke, he rushed towards the group of humans with dozens of orc soldiers, although Gavin gathered the soldiers, but the formation of these soldiers had long been disrupted, and it was impossible to form a military formation in this environment.

Originally, these humans were not the opponents of the orcs, and there was no military formation, and under the collapse of morale, they couldn't stop these wolf-like orcs at all, not to mention that these orcs were all the elite of the orc tribe. As soon as the two sides came into contact, the human soldiers suffered heavy casualties.

The soldiers who had just gathered together were instantly stunned, and seeing this situation, the orcs attacked even more desperately, and the human soldiers scattered one after another wherever they passed.

Seeing the orcs rushing up, Gavin was furious and raised his weapon and was about to step forward, but the guards beside him hurriedly hugged Gavin and dragged him away.

Just when the Blackstone Fortress fell into chaos, the orc army that had been waiting for a long time showed its fangs at this moment, and one after another siege vehicles and siege towers were pushed onto the battlefield, and the orc shamans blessed these orc soldiers with various spells.

The human defenders were constantly projecting rockets to attack, but the chaos in the city made it impossible for humans to concentrate their forces. The rockets projected became so thin that they couldn't compare to what they were during the day.

And the orcs siege equipment is more than twice as much as during the day, it turns out that the orcs have already made enough siege equipment, but in order to paralyze the human race, they use a part of it every day, and now when it comes to the critical time, all the engineering equipment is directly sent.

Vane, who had just arrived on the city wall with his guards, felt a chill rise in his heart after seeing the orc army besieging the city.

"Damn the orcs, they've been preserving their strength all along!" Vane gritted his teeth and said, in the eyes of humans, orcs are all muscular, simple-minded creatures, but he, the commander of the army, was played by the orcs who had always despised him, how could this not make him angry.

It's just that now even if he knew it, he was helpless, and a large number of siege equipment quickly advanced towards the city wall under the impetus of the orc army, and the human defenders looked panicked.

"My lord, the Blackstone Fortress can't be defended, we must evacuate!" several red-robed wizards said after glancing at the scene.

"No, it can't be withdrawn, the Blackstone Fortress is a barrier to the northern provinces, once it is lost, the orc army can no longer be stopped!" Vane said angrily.

"There's no way around you now, look at the soldiers around you, they've lost their courage!" the wizard sighed, then pointed to the human soldiers on the city walls, who had already begun to sneak away.

Vane silently put down the weapon in his hand, as the commander of the army, he saw that those soldiers had no intention of fighting, this fortress could not be kept tonight, but he was unwilling!

The night wind howled with a hint of chill.

"Team, let's evacuate!" Vane closed his eyes in pain, and then gave the order to retreat.
