Although the cave was big, it wasn't big enough for one hundred meters tall creatures to enter while standing and keeping themselves at that size. So, everyone had to return to their standard sizes while Leon was transporting their equipment using Telekinesis.

Much to Leon's surprise, the cave was pretty near the ocean, and there he could found the same krakens and ancient horned whales. But there was an interesting addition to the sea creatures of that world… a busty woman who had lower-half of a fish… and she wasn't wearing any clothes! The beast wasn't just sexy. It was incredibly beautiful… almost unrealistic beautiful. The moment Leon looked at her, he felt something entering his Mana Dominion… before he could get mesmerized even further, he shot his full-powered Magma Spears at the creature, obliterating it.

...

Leon couldn't help but frown once he killed the creature. For some reason, the head of the beast escaped his attack, and that made him feel depressed… because the mermaid also had the head of a fish…

"Great… now monsters can also play with my brain…"

When Leon looked behind, he saw Inglar, Ivolaer, Jorhorn, and Jertien looked away… it looked like they have been mesmerized too. But unlike Leon, they didn't notice that something was wrong. Meanwhile, Alurelle, Ismenria, and Genelosa seemed pretty okay.

"I guess mermaids can't charm other women…"

Leon didn't even have time to use Appraisal, the very moment he looked at the creature, he got caught by its illusion… it wasn't an enemy. He could analyze or go easy. Otherwise, he would become a minion of a monster.

"A new type of monster…" Genelosa sighed.

"At least, it isn't that strong," Ismenria frowned. "But to use that kind of power… how shameless."

"Let's just be thankful that Leon noticed on time the trap," Alurelle said.

"The hell am I thinking the same day I arrived in this dangerous world?"

Anyway, even though Kraken and ancient horned whales were monsters that only appeared in the world that were on the second stage of evolution, those mermaids weren't. By the look of things, they didn't treat other monsters like enemies either. And that was a relief. The harvesters would be able to find food to maintain their gigantic form… as long as Leon is around to keep the mermaids at bay, because they also found merman, and they could charm the females of the group.

After securing some food, the harvesters and Leon reunited at the cave. Although he was part of the group, Leon didn't know all that much about what they should do. This was one of their planets, so the harvesters probably would have better ideas of how to proceed. So, Leon decided to plant the blue angel leaves while they talk.

"What now?" Ismenria asked.

"We will decrease their numbers until we have the chance to attack their dungeon on the central continent," Jorhorn said. "We will have to be patient in order not to let their leader discover about us. That guy isn't a maniac like the others, and he is pretty smart… if we get careless, he will destroy us again."

As expected, the angels had a leader and considering things Leon knew so far. It probably was an angel who also was a dungeon boss. Strong and smart… it wouldn't be an easy opponent. Still, now that he was on that planet, Leon started to wonder how their plan would work. They couldn't seal a dungeon, opponents of that level could quickly destroy any barrier that the harvesters might create. So, trying to seal the dungeons would be the same as creating a time-bomb.

"The easiest option would be to strengthen someone to the point where that person can clear all the angels that leave the dungeon, even the boss, but that person would have to stay behind the moment they reconquest the planet. And that would make things difficult on the other planets…"

"What about the monsters of other dungeons?" Alurelle asked.

"For the time being, we will ignore them," Jorhorn answered. "We don't know the changes the dungeons suffered when we reached the third stage of assimilation. Besides, the angels are by far the most troublesome enemies. As long as we keep defeating them, we will grow stronger, and the difficulty will decrease… at least regarding the fights against non-bosses."

Leon made a mental note about that topic. He also had to memorize the changes and number of dungeons in that world. Things on Miebos were a bit different and rather irregular, thanks to that shadowy figure. However, all information would be useful later when Leon returns to Earth… as long as he returns to Earth on time.
