A few hours later, Leon and the harvesters finally managed to secure three more dungeons. Genelosa and Alurelle stayed behind to defend the previous two dungeons.

"You will stay here," Jorhorn declared. "Eventually, we will return and confirm our success to you."

Leon looked around and saw the corpses of hundreds of angels and some mermaids. The dungeon was located on a beach on the southern part of the northern continent, and that only meant one thing, Leon would have to guard the dungeon, which was the closest to the central continent.

"Even if your powers are not enough," Jorhorn smirked. "Considering your new spell, you should be able to deal with the monsters here."

Leon indeed was weak in comparison to the mob monsters of that world, but he didn't want to hear that from him. Still, Leon decided to shut up and just nod. The elemental advantage would help him, as much as he wanted to create weapons using the spirits of cyclops, reptilians, and centaurs, and even seeing them, Leon had to move at the correct pace.

Fortunately, even the angels needed the light of campfires to fight. So, Leon didn't have to create one after Jorhorn and the others left to clean the other camps.

"Let's see how much I improved against those mermaids… Also, I should keep my eyes off their boobs just in case."

Half of the mermaids' dungeon was underwater, so Leon had to be careful in order not to let them flee to the ocean. However, that wasn't a problem, thanks to Mana Dominion. That skill was at a level where Leon could feel anything within two hundred and twenty meters around him. The very moment three mermaids left the dungeon, it was the moment where Leon electrocuted them with two Thunder Rays. Although he only managed to hit two directly, the ocean conducted the electricity and also shocked the third monster. After being hit for five seconds, all mermaids died.

"Thanks to the elemental advantage, I can kill them using the same amount of mana I would have to use by using Magma Spear… isn't half bad, but… it is all thanks to these rings."

It was a weird feeling, Leon created those rings using his own power, but couldn't help but feel frustrated… it was probably because after he left the island, he didn't have much of a hard time against the monsters. Or perhaps it was because Thunder Ray wasn't that awesome as he imagined it would be.

"My standards when it comes to magic are too damn high… There is no spell that I want more than teleportation, after all."

Congratulations! The skill Thunder Ray has leveled up.

Leon managed to level up Thunder Ray quite a bit before morning came, surprisingly, soon after things became brighter again, Jertien appeared.

"Hey, there," Jertien said. "It looks like you have been guarding the dungeon well."

"Where are the others?" Leon asked.

"Protecting their respective dungeons," Jertien answered. "Soon, I will have to do the same, but before that, I have come to tell you something. We will need you to create Checkpoints near the dungeons and connect them to our tower. We will use that in case something happens and when we feel like resting for a while."

"So, everything went well?" Leon asked.

"Yes, you don't have to worry," Jertien smiled calmly. "Despite our numbers, we managed to secure all the dungeons. Anyway, you will have the chance to use this dungeon as much as you want. However, to save time, you will also have to help us move from our base to the dungeons."

That would be a massive pain in the ass, but considering the situation, it couldn't be helped. Leon could only Transfer himself and others to a point where he could see with his eyes. That plan was a bit risky, but it wasn't like Jorhorn could solve that problem just by thinking of something. Again, Leon could solve everything by using Summon Zombie, but again he decided to stay quiet about it.

"All right then," Leon said. "I will do that."

In the end, Leon would have a dungeon to train by himself. It was a dungeon of a world that was on the third stage of assimilation, so he couldn't ask for more at the moment to grow stronger.

It took Leon an entire day to create the checkpoints in all dungeons, but in the end, even though Checkpoint wasn't as useful as Transfer, it would be helpful in the future.

For a few days, Leon did nothing but killed mermaids. Some mermen noticed the slaughtered caused by Leon and came from the sea to attack him, but they suffered the same fate. Regardless, even though Leon didn't enter the dungeon, but only checked the shop now, and then, Inglar and Ivolaer did, and they also learned something interesting. If monsters wanted, they could use the purple crystal of the dungeons to return to their own planet.

"I didn���t remember monsters doing that back on Earth or Miebos… I guess this is only possible because this world is on the third stage of assimilation."

Another weird thing about those dungeons, it was the fact that they didn't spawn any boss. That was weird since Leon was pretty sure those six angel generals were bosses… or at least he imagined that they were. Although most mob monsters were troublesome alone, the fact that the dungeons didn't spawn bosses helped Leon… at least that was true gainst mermaids and merman.

"I just hope nothing will happen for a while… although I can use the Checkpoint or even Transfer to escape, I really need to grow stronger as fast as I can."

Maybe those words were one of those death flags, but Leon couldn't care less about such a thing. Although he was hoping for the best, he would never stop preparing for the worst.
