"Remember, level three mages and level three monsters go through one of the biggest changes that makes lower-level ones unbeatable."
All three of them nodded in agreement as Katherine started burning the spider's body with a massive fire.
At the same time, a gate appeared right behind the body, leading up to a pitch-black room that didn't reflect any of the outside lights at all.
"You three prepare for the last room?"
Katherine's question cheered them up a little after losing their chance to fight the spider boss.
"What's behind the gates?" Alex curiously asked as he picked up his sword that had fallen onto the floor.
"You all will see it when you get there. Are you all ready?" Katherine asked as she put her hand on the button next to the door.
With a nod, Katherine pressed the button, causing the gate to reveal a long hallway just like the room they were in.
The room was almost filled with hundreds of skeletons, all with swords and even shields, as the two rooms were now merged.
More importantly, all of them were alive with blue flames in their eye sockets as they looked over at the four of them.
Alex immediately stepped up in front, showing zero fear as Sophia and Mary began casting their spell.
With Katherine turning invisible, the skeleton's attention was focused on Alex, who charged in with a wall of light element covering in front of him.
Almost every skeleton he ran into fell onto the floor before he ran out of mana to keep up the light wall.
Just as Alex started to run back, ten orbs of light flew right into the crowds of skeletons, causing massive gaps in the skeleton formations.
Still, it quickly filled back up after the orbs of light ran out of steam, disappearing as more skeletons filled in the gaps.
"So many skeletons! Alex, do you think we can beat this?" Sophia asked as the two of them started casting another round of spells.
"Just keep doing it. I'm sure there's a limit to how many skeletons there are."
Alex kept on getting into close-range combat, with his occasional light wall covering spots where his shield couldn't.
Every second that went by, he was being slowly forced back, retreating towards the entrance to avoid being surrounded.
With more and more orbs of light being shot by Sophia and Mary, the skeleton army finally started to dwindle.
Soon, they were about to kill half of them as Alex had been pushed all the way back to where Sophia and Mary stood.
"What do we do now?" Mary asked as they were now surrounded by skeletons, with the wall behind their back.
The only thing holding them was the light barrier they cast, which was starting to crack as the skeleton kept attacking it.
"We'll just charge our way out. Cast a barrier on my shield and just follow right behind me."
Just as the barrier was about to break, Sophia and Mary withdrew their mana from holding it up.
Alex immediately charged out, holding the shield lit up with a strong light with both hands before full sprinting it like a bull.
Fortunately, his gamble paid off as he picked the thinnest part of the skeleton army to break through.
The three quickly continued running forward until they were at the opposite end of the room, with tons of skeletons now chasing after them.
With a small break to regenerate their mana, the three of them began casting orbs of light right at the remaining skeleton army.
By the time the skeleton army reached them, only ten skeletons were remaining.
"Let me clean this up. I want to try to beat this myself."
Neither of the girls said anything, but they cast a layer of light over his body.
As Alex charged in with his sword and shield, he blocked the right skeleton's attack while swinging his sword to the right.
The slash was enough to neutralize one of the skeletons as he jumped backward to dodge the other attacks from the side.
Next, he made his next move by running to the side, forcing the skeletons to clump up as he charged in again.
With a stab, he cut one of the skeletons' heads right off before raising his shield to block one of their attacks.
Alex continued to dance around the skeleton, making occasional attacks, using its immobile movement as its weakness.
"Can you finish already?" Sophia complained as she was starting to get a little bored watching the sword fight.
"Fine."
Alex recklessly charged at the last two, shield slamming one of them down before swinging his sword at the other one.
"Finally, we're done..." Mary murmured as Alex went over to a few of the neutralized skeletons, stabbing them in the head to end their life.
"Mom, we're done, right?"
Sophia asked as she noticed Katherine still nowhere to be seen, as if there was still a fight coming up.
"Mom?"
Alex and Mary quickly realized something was off as well, as they couldn't find Katherine anywhere in the room.
However, before they could say anything else, dark elements suddenly began to cluster in the middle of the merged room.
"Shit, there's another boss!"
Both of the girls immediately moved behind Alex, letting him stand before them as they had already begun casting their spell.
As the dark element surrounding the center slowly disappeared, a skeleton with full knight armor appeared.
It held a giant greatsword with both hands, slowly turning its head towards them as the blue flame glowed through its helmet.
"I can definitely not tank that," Alex murmured, already picturing his arm being shattered if he tried to block it.
Still, Alex stepped forward to create some distance between him and the two girls as he raised his weapon.
"Come on, swing at me if you dare."
Alex flat-out threw his shield at the skeleton before running to the side, drawing the skeleton's attention.
The skeleton knight immediately became enraged as it started charging towards him with its greatsword.
Alex immediately bolted away, yet the skeleton knight somehow managed to catch up despite wearing full armor and wielding a massive sword.
With no time to think, he took a quick turn as the skeleton swung his sword down onto the floor, creating several cracks in the tiles.
"Thank god that sword is slow—"
Just as Alex was relieved at the slow swinging speed, the knight suddenly raised his sword and swung sideways.
Alex was forced to raise his sword right, sliding across the floor as he didn't try to push back against it.
"God damn, this thing is strong," Alex murmured as he could still feel his ankles almost broken from sliding so much without falling.
Every second that went by, his legs were getting real tired. It was starting to reach the point of no return.
"Fuck it!"
This time, Alex didn't try just running away.
He started casting several rock spells and hurled them right at the skeleton, which delayed several of the attacks.
It was just enough time for Alex to dodge the vertical and the horizontal slash as he started rolling around instead.
Soon, he realized he could force the skeleton to swing at awkward angles as he rolled closer, allowing him occasionally to stab at the knight.
Although it couldn't scratch the armor, Alex was still doing it to keep the knight's attention on him rather than on his sisters.
"What's taking you all so long?" Alex asked, his head starting to feel dizzy from rolling underneath the skeleton so much.
"Just a few more seconds. We're trying to make a big one!"
As Alex turned for a split second, he was shocked to see a massive orb of light, four times the size of the skeleton knight, hanging in the air.
In a split second, his mind came up with a plan. He immediately withdrew from being so close to the skeleton.
Next, he started running at full speed, lunged towards the two before falling flat onto the floor as they finally finished casting the orb of light.
The skeleton knight seemed to finally notice the magic as it charged right at them at full speed, getting ready to pierce it with his sword.
"Take this!"
With a blinding bang, both girls were forced to cover their eyes as the orbs of light hit the skeleton knight.
By the time the light disappeared, the skeleton knight had vanished, with the only thing remaining being its great sword.
As Alex stood back up, the great sword evaporated into small particles, and the room was now finally at peace.
"God damn, that felt so scary...' Alex murmured as he still couldn't believe he managed to stall for that long.
He could still feel his heart pumping like crazy, every part of his muscles feeling sore, unable to calm down at all as his hand kept on shaking.
"That thing looks even more intimidating than the spider."
Sophia commented, still feeling a little scared after seeing the skeleton knight making a desperate charge at the last second.
"Mom! Are we done yet?" Mary impatiently asked, her mind starting to regret exploring the dungeon.
"Yep, you guys are done! That was the last boss of this dungeon."
Katherine finally appeared from the shadows as she began walking towards them, clapping and looking a little proud.
"Mom, was that a level two mob?" Alex curiously asked.
