Phasing through the fake wall in the sewers Marcus came back into the corridor that leads into the necromancer's lair.
Looking around Marcus noticed a few doors and another passage leading deeper into the complex.
Popping his head through all of the doors, most of them seemed to be just storage areas that were not in use but one of them had crates full of grave soil and powders Marcus did not recognize.
'I do not know anything about necromancy in this world so maybe these are ingredients to make things like zombies or something. Well, it does not really matter, once I kill the necromancer it will al just be junk anyways.'
Finding that there were no other obvious or hidden passages, Marcus directed his attention to the corridor that lead farther inside the lair and seemed to give off an ominous atmosphere.
'Okay no need to be afraid if people here that a ghost was getting spooked by something like zombies or skeletons they would laugh. In fact, if I think about it that way, I am the scariest thing down here, so they should be afraid of me.'
Getting his nerves steady as he was expecting to run into the impending creatures of undeath Marcus floated along down the corridor anticipating a jump scare at any moment.
Luckily, that scare never came as after around a minute of floating Marcus came to another room with corpses piled up in it that had two doors at either end.
Checking around to make sure that their was no one in the room with him, Marcus checked the door to his right first phasing his upper body through to have a look around.
On the other side of the door, he saw another fake wall that would lead back into the sewers. Satisfied that this was not the right way to go he turned around and headed to the opposite side of the room where the other door was situated.
When he poked his head through this door however, Marcus nearly had a heart attack as he noticed dozens of zombies and skeletons moving around.
Pulling back with a start, if Marcus could breath he would have been panting in fear right now as would anyone who abruptly saw a bunch of corpses shambling around.
'Fuck I knew it was coming but in some ways that made it worse. I just need to calm down a bit this world is a lot different than Earth and undead are just another type of monster. I have killed hundreds of other monsters and these guys will be no different.'
After calming himself down and thinking about it rationally Marcus was ready to confront the horde of undead that lay behind the door.
Floating back through Marcus rematerialized and prepared for battle, except none of the zombies or skeletons attacked him. Standing their baffled Marcus walked right in front of one of the undead but there was still no reaction.
'Huh, guess they will not attack another undead, well if they did, they would all be fighting each other. At least this gives me ample time to prepare.'
Marcus then checked the different undead finding that their levels ranged from seven to sixteen which was not really a threat to him.
Then with the knowledge of their level's Marcus figured the best way to get rid of the horde of undead would be to let his iron golem squash them since it would have been too exhausting to try to kill them all alone.
Summoning his iron golem their was still no reaction from any of the undead so Marcus just ordered it to crush all of the zombies and skeletons it came across.
The iron golem then moved over to the nearest zombie raised up its fist and brought it down and under the enormous pressure the zombie splattered all over the place.
As the first zombie was destroyed the other undead in the room finally began to react, keying in on Marcus and his iron golem as the threat that had just attacked one of their own.
The hoard of undead then rushed towards Marcus and his golem. The hundreds of zombies and skeletons began throwing themselves at the iron golem trying to tear it apart with little success. Most of them were barehanded and fruitlessly clawing or biting at its solid iron frame while the few with crude weapons managed to inflict no more than a few dents and scratches. The iron golem also did not remain idle during this time stomping and thrashing the undead swarming it, destroying many of them with each of its devastating attacks.
While most of the undead horde were attacking his iron golem a few did slip by and come towards Marcus.
With the fast-approaching zombies and skeletons coming for him, Marcus brought out his scythe and cast his iron sphere spell.
As the first skeleton approached him, he sent his iron sphere barreling through its boney body smashing it to bits and rendering it unable to move. He next swung his scythe decapitating a zombie that was running for him.
After a while when the horde of undead were slowly decreasing Marcus ordered his iron golem to advance down the hall while destroying the undead in its way.
His iron golem then slowly advance swing its arms and stomping down any undead unfortunate enough to cross its path.
Some of the undead though were lucky enough to slip past the rampaging iron golem but unfortunately for them they were greeted by Marcus' scythe and iron sphere.
Eventually with the help of his iron golem Marcus had managed to destroy the entire hoard of undead though his iron golem did look a bit worse for wear after being assaulted by over a thousand zombies and skeletons.
'Well, I suppose a death by a thousand cuts really is a thing, even though my golem is now level twenty-three these guys managed to slowly chip away at. Guess I will just summon another one.'
Letting his first golem crumble into nothingness Marcus recast his tier four iron magic spell and brought forth another one.
With his new golem ready to be his punching bag incase of another undead horde Marcus set off deeper into the hideout.
Walking for around a thousand feet he eventually came to a large double door that had two skeletons in full armor guarding it. Checking their levels, he found that one was twenty-one while the other was twenty-two.
'So, he did create some formidable undead after all, I was wondering if all he had were basic zombies and skeletons.'
Looking over the two high level skeletons Marcus quickly came up with a plan to defeat them easily.
Walking forward nonchalantly with his iron golem at his side the two skeletons reacted to him once he was within a hundred feet of the door. The two armored skeletons then drew their swords and shields and charged towards Marcus.
Of course, while these two skeletons had higher levels and impressive gear in comparison to the others Marcus had faced, at the end of the day, they were still mindless undead programed only to attack intruders.
When the two skeletons were only around ten feet away from Marcus, they suddenly fell over face first on to the ground tripping on Marcus' iron threads.
Having expected this from the start Marcus had already ordered his iron golem to attack when they fell over, and it quickly slammed each one of the skeletons' heads with its fists.
Even with their steel helms, under the immense force of the iron golems attack their heads were crushed helm and all.
This however was not the end as even without heads the higher-level skeletons were still able to get up and began assaulting Marcus' Iron golem.
Unfortunately, even with their higher levels they had a bad matchup against the iron golem and were soon crushed under it and Marcus' power.
'Well, they were a little tougher but after destroying all of those undead with minimal effort I see it was stupid off me to be scared earlier. But now that I have taken out all of the sentries it is time for me to deal with the boss.'
Turning his attention towards the large double doors, Marcus walked forward ready to finish up his request and kill the necromancer.
