Duke knew very well that he could not stay in Karazhan forever.
Outside, Stormwind was under siege, and the green frenzy of the orcs was raging across the entire continent. From any angle, he had to rush back as soon as possible.
The task of defense can only be left to helpers such as Khadgar and Michael.
Although the Heroic Warriors may be much higher in rank than the original Stormwind elite soldiers, fighting demons is like fighting orcs. It is meaningless to simply fight with numbers. Unless they are guys like Lothar who have entered the realm of heroes, no matter how experienced the elite soldiers are, they will not be able to please the demons.
Duke suddenly recalled a game he had played before, and combined with a book called "Compendium of Mechanical Traps" he found in Medivh's library, Duke came up with an idea.
108 mage hands appeared. They flew across the first and second floors of Karazhan. They unloaded the wood Duke needed with a creaking sound, and even uprooted some pillars in the stable. Duke injected arcane energy into the earth, allowing the huge stone bricks to break free from the constraints of gravity and fly into the air with the soil.
He looked like an idiot, watching Duke, who had not mastered a lot of magic theories before, transforming the entire structure of the first and second floors of Karazhan like building blocks.
"Damn it, even if Karazhan is located in the gap between time and space right now, Karazhan will still collapse if you mess around !" Khadgar screamed.
"What? Do you know anything about architecture?"
"Huh!?" Khadgar was a mage, not the old foreman of the Brotherhood of Stonemasons. He was immediately confused when Duke said this: "You understand?"
"Of course, as long as the supporting columns and load-bearing walls are not moved, it won't be a problem even if I hollow out the first and second floors. Besides, I've calculated the gravity here, and it's only about 80% of that outside. I can move more sharply."
Although Khadgar didn't understand what Duke was saying, he felt it was impressive!
In this way, Duke spent about a day turning the entire first and second floors of Karazhan into a huge death maze.
Spike traps, asphalt traps, arrow wall traps, spring traps, blade wall traps... combined with some gaps that could lead directly to the turbulence of the void, Duke ran into a push trap that could knock away a huge body larger than a ton.
Everything is ready, except for the devil.
Two days later, at the main entrance of Karazhan, the red and black chaos void parted. A thick green light that was not too dazzling, like the light of moldy pea soup in dark cuisine, illuminated the main entrance of Karazhan.
In Duke's perception, an evil aura pierced through the chaotic void and connected directly to Karazhan from an unknown world.
A huge crack was forcibly torn open in the space, and some kind of magic was rapidly reinforcing the crack. A terrible smell that was almost tangible and evil poured out from the portal. Duke, who was sitting at the end of the second floor, could also quickly smell the unpleasant smell.
Khadgar, who was beside Duke, changed his expression slightly. After seeing Duke nod, he came to a crystal ball flashing with arcane light and pressed his hand on the crystal ball.
That is a soul crystal ball that can connect to the spiritual seas of all the heroic warriors on the first and second floors.
"The guests have arrived! I repeat, the guests have arrived."
As the words fell, a huge red gauntlet was placed on the edge of the portal at the main entrance. The next second, a humanoid demon with a height of more than five meters and scarlet dragon wings stepped out of the portal.
He had explosive red muscles all over his body, and was wearing heavy armor. His head looked a bit like that of a rough orc, but he had huge horns on his head, which orcs didn't have. His strong thighs were like goat legs, not only folded backwards, but also had huge hooves.
The blazing flames wrapped around him, contrasting with his huge body, made this Doomsday Guardian look extremely hideous and terrifying.
"Kill all the rebels here. Master Sargeras cannot die in a place ! Search! Search them all! Even if this place has to be completely destroyed, we must find the passage leading to the master!" The giant demon was roaring at his subordinates in Eredun, which is commonly known as the demon language by humans.
Countless terrifying figures rushed out from beside him.
There is a demon hound with a red body, crawling on all fours, with two long black and white tentacles and two huge horns.
There were also demon guards with bare upper bodies, indigo skin, and strong chest muscles. In addition to the bare upper body, the demon guards' arms and the area below the waist were all wearing heavy armor that was mainly red with white edges. On his head and back, there were long, red horns growing out.
There is also a set of armor, and the real body is actually a void demon with an inverted triangle of dark blue energy.
They rushed forward in a chaotic manner and rushed into the long passage at the entrance of Karazhan.
Suddenly, the fastest hellhound seemed to step on something. All that was heard was the sound of metal rubbing in the darkness. The next second, dozens of sharp spikes sprang out from the floor, piercing the hellhound's abdomen as if they were going to make a skewer of it.
As the scout and vanguard of the demon army, the hellhound had an agility that Duke didn't know. At the moment when the spikes were about to touch its abdomen, the hound suddenly arched its back and bounced into the air like a spring.
Unfortunately, without any warning, a two-meter by two-meter square block suddenly fell heavily from the low ceiling, and before the hellhound could do anything, it was knocked back to the ground.
"Swish!" With a sound, the sharp metal spikes ended the life of the hellhound.
Accompanied by a series of "clacking" sounds, the spikes were retracted into the ground, and the ceiling that had fallen for a distance was pulled back up by the stirring gears, quietly waiting for the next victim.
Of course, more than one hound was hit.
As the demons were charging forward, there was a sudden "bang". A huge demon that could easily kill twenty elite human warriors was suddenly bounced away by a metal floor tile that bounced up from the ground.
The unfortunate guy was caught off guard and was ejected with a loud bang, like a cannonball stuffed into the barrel of a gun.
Demons are not beasts without intelligence that only know how to kill. The strange situation surprised them. Their eyes followed the victim's figure until the victim hit a wall and stopped, and then their pupils began to focus.
Before they could shift their focus, three sets of crossed giant axes suddenly appeared on the seemingly ordinary wall. They were exaggerated axe blades that even ogres would find too heavy to lift.
The axe blade, which was over one meter in diameter, could be used to chop demons, and even a dragon's neck could be easily cut off if placed on it.
With a chilling cold light, the demon only had time to let out a half-scream before the cold light of the axe blade flashed across his body. On the wall, only a few deep cracks remained, as well as the demon's blood splattering in all directions and scattered pieces of flesh that could no longer be pieced together.
