Kahn and his subordinates set up an ambush at the other end of the narrow tunnel while Oliver successfully led a group of 10 skeleton undeads by shooting arrows around their surroundings and attracting them using the noise.
The completely fleshless bodies of the skeletons clattered while walking as their bones hit each other and their zombie-like walk took a lot of time for them to reach the other end.
Kahn who watching this through Oliver's vision also noticed that there was a small amount of visible black smoke leaking out of these skeletons. And it was nothing else that the Dark Magic that was keeping these bodies intact and move them.
But as soon as the skeletons entered the proximity.. They sensed a life form and suddenly, their hollow eyes glimmered with a fiery red glow. The unmotivated bodies of the walking dead now suddenly showed a hint of intelligence and gazed at the living being that was leaning against a wall.
There was a figure of a human who was sitting against a wall and the cold floor at the other side of this small cave-like space. His arms were folded together and his eyes were closed. He looked completely carefree and didn't mind the group of undead looking at him with malicious intentions. The group of skeletons sprung in action and ran towards this humanoid creature.
The humanoid and carefree figure was none other than Kahn.. But at this moment, his head was leaning against the wall and didn't seem to care if someone was attacking him. Because at this moment, Kahn was..... Sleeping.
Yes, during an incoming attack.. Kahn was dozing off without the care of the enemies.
Clatter! Rattle!
But before the skeleton undead could even reach halfway to their target, a reddish and tangible barrier was cast upon them and suddenly; their boney bodies no longer produced any sort of sound.
Ceril who was standing on top of a small boulder waved his hands and the area of this silence barrier enlarged more than twice the earlier size.
A giant figure of a black and furry Lycan jumped inside this barrier and in just a few seconds, it utterly decimated the skeletons; breaking their entire bodies with a few swipes of his claws.
"I already gave you lot a feast yesterday. There are no free meals in the world. So keep on going." commanded Kahn and went back to his merry sleep.
He was acting as bait to lead the skeletons to attack him the moment they saw him and enter inside their already prepared ambush hotspot.
This way, his subordinates could take them out effectively without wasting any time or produce any commotion that would alert the Lich for the first few times.
Now Ronin & Oliver both started the work of luring out the undead while Ceril handled the silence barrier and Omega and Jugram finished them off.
The first two waves were of only 10 skeletons but then both the subordinates started bringing in more enemies by themselves as if there was some sort of competition between them.
Although their numbers were increasing, in front of a Lord rank monster like Omega and a berserker like Jugram, they stood no chance as they always walked in the trap of attacking Kahn as soon as they sensed his presence.
Little by little, they started whittling down their numbers and in the span of 3 hours, Kahn's subordinates had managed to kill more than 200 of these skeleton soldiers.
Since these skeletons didn't have any weapons on them, they could barely put up a resistance against the duo of Omega and Jugram while Ronin & Oliver kept bringing more skeletons to gnaw on.
Kahn who finally woke up from his nap and yawned suddenly heard a loud march of footsteps from 600 meters away from the other end of the tunnel.
"So it begins.." he said and ordered both Oliver and Ronin to openly attack and bring the horde of the enemies through the tunnels ran towards their direction.
"Everyone, get ready!" said Kahn and the remaining of the Six Generals and the Legion jumped out of his shadow and finally prepared for a frontal clash.
THUD! THUD! PITTER! PATTER!
The army of the dead charged through this narrow tunnel, each line containing only 4 to 5 skeletons at most while they were walking in exactly the spot where Kahn wanted them to be. The biggest problem was going to be none other than those Skeleton Warriors the floor boss had created.
Just 2 of them were enough to hold off one Lord rank subordinate of Kahn. So 8 of them were enough to hold off his top fighters. And that's why Kahn had chosen the narrow tunnels so that they won't be overwhelmed in terms of numbers or combat power.
Both Kahn and Ceril attacked the incoming horde with their large AoE and destructive fire, wind & lightning spells while Blackwall, Jugram & Omega facing them head-on along with the Minotaurs and the Nymphs from the Legion.
Kahn's side had a total of 52 fighters while the opposition still had more than 300 members left.
"Still not taking actions by itself? Or perhaps it can't leave that place?" asked Kahn as he noticed that everyone from the enemy side except the Undead Lich itself didn't come to attack him.
"Attack!" declared Kahn as his side attacked and engaged with the enemies that were coming in small groups and even his stealth-related subordinates joined this arduous battle of breaking bad.. Urmh, breaking bones.
Without the Lich itself ordering the undead army, there wasn't much resistance these 300 or so skeletons could put as they entered little by little through the tunnels and were destroyed in a full-blown ambush by his side.
Kahn used Firestorm and Windcutter simultaneously and killed far many skeletons compared to his subordinates. His advantage in Mana & Long-range attacks helped him a lot.
After breaking through the Grandmaster rank, he was far more powerful than before and his attacks with mage spells and sword had already reached a point where these small-timers proved no threat to him.
Another 2 hours passed as he finally managed to kill the remaining army of the undead. Even the giant monsters were taken care of under Kahn's impeccable coordination with his subordinates. They were all Unique Rank monsters at the end so his side didn't have too much trouble taking care of them.
He put a High-grade Health & Stamina recovery potion in his mouth and prepared to meet the Lich.
He couldn't get any cores or absorb abilities from these undead so he didn't bother spending any time on them.
He traveled to the Lich's location with his own army this time.
"Human.. Do not think that you've won. You only gained some more time before your death. For I am the death, for I am the eternal Darkness. I am a God!" spoke the Lich floor boss who was wearing long and hooded purple mage robes.
Kahn looked at the fiery red eyes of the undead Lich and spoke..
"I don't time have to listen to your monologue, you wannabe Ainz Ooal Gown." replied Kahn.
"Now.. Let's get this party started!"
