The Supreme Level Up System

After doing that a few times, everyone noticed that the ground was starting to shake, and the monsters were approaching faster, but the pressure caused by the heat was intense enough to make everyone think that it was about to explode.

"Is this how it will happen in the future?" Seris asked while furrowing her eyebrows.

"I don't know, but this is how I want to make it happen now," Aion shrugged.

"Don't you think that the enemy is here?" Seris asked while wondering why the monsters still were coming in that stupid manner.

"Most likely not… they are a different type of creature than humans. I would like to think that they are better suited to moving between timelines than most, though," Aion explained. "That being said, their sense of self-preservation is strong enough to try to change the past without coming directly out of fear of meeting me."

"Those are a lot of assumptions…" Seris furrowed her eyebrows.

"Still, I think that Aion is correct… everything that thing did was to interfere indirectly with the timelines once it was unable to defeat Aion in the timeline I came from," Arlana explained. "That thing is troublesome because it becomes more knowledgeable and resourceful over time."

Just like an AI programmed to learn by trying again and again… such a creature sure was interesting as it was scary. Aion couldn't help but think that given enough time, it could even become a problem to the giant calamities.

In any case, Aion has forgotten about that since. Eventually, the trembling became so powerful that Aion summoned several ice walls around them. Eventually, the dungeon exploded, and like an eruption of steam, a lot of hot air emerged from several fissures that appeared around them. The heat and pressure had been so high that they even reached the clouds and pushed them away, revealing the blue sky that was so rare in that area.

Bloody Zombie: at the cost of fifty points of mana, you can summon a bloody Zombie that will have all of its parameters equal to the level of this skill multiplied by three. You need to use the blood of a corpse to summon it.

Vampirism: it grants you the power to recover health when you are attacking a target directly or when you are using the skills of this class. The amount recovered will be equal to three points of health multiplied by the level of this skill.

"Bloody Undead… but it is just like the abilities of a primordial vampire," Aion furrowed his eyebrows.

In any case, the land eventually stopped trembling, but they had to wait for a bit since a lot of rocks were fired upward, and Aion had to get rid of them before they could smash him. He was in a good mood since he could feel that the mana around the dungeon had stabilized and the temperature had decreased.

"It will be hard to find the way to the end of the dungeon now… while I don't think you had any other option, the path will be completely filled with rocks and earth," Seris said once they approached the entrance of the dungeon that now was just a large area of destroyed land.

"Nah, it will be fine," Aion said while he was increasing the refinement of the Necromancer class again.

At the same time, Aion took out several bodies of earthworms from his inventory since he didn't have time to process them until now and used them as a catalyst to create skeletons. They began to dig around while helping Aion, who was using earth magic.

In the end, it took three hours for them to reach the point where they found the magic door. It had lost all of its magic power and became just a huge chunk of metal… Aion still stored it in his inventory, though.

Although the whole dungeon had collapsed, that final part which was basically a massive shelter that had walls, a ceiling, and a floor made of stone, still was standing. It had some cracks here and there, but it looked fine, thanks to the numerous stone pillars around it.

"Why is the final part of the dungeon like this when it makes spawn magma golems?" Seris asked while frowning.

Aion was also thinking along those lines, and he could only assume that it was something that had been built way before the dungeon was formed. Maybe it was just a coincidence that the final part of the dungeon and the monsters didn't look alike in any shape or form.

"What did your brother say that dungeons and labyrinths were again?" Aion asked.

"... Dungeons are like a defense mechanism of the world, and we can say that the labyrinths are like the offensive mechanism. They keep growing stronger and larger the longer they exist. They only stop working when they want… many countries in this world were abandoned due to their existence and their inability to destroy those things," Seris quoted Sauros' words exactly. "This is what he said before."

Aion recalled that… dungeons appear when certain parts of the world are suffering a lot due to the human hands. Still, no one lived in that area in hundreds of kilometers, and yet… someone built that place who knows when.
