Reborn in a world where people can communicate with elves, Yang Fan becomes a gym leader who is about to inherit the gym.

But because his initial Pokémon was an extremely weak and timid Ralts, he was about to be kicked out of the gym as the gym review was imminent.

At this critical moment, obtain the elf development system.

"Your Larulas, blaming himself for being too weak, decided to mutate into darkness and evolve into Kirlia!"

"I'm so happy that your jackrabbit is going to square dance with you. I'm giving you my treasured mega stone!"

"Your Milotic has activated a skill buff because of taking a bath with you. The power of all water-based skills has increased by 30%!"

Chi: The only gym I haven't fought in is Yang Fan's!

Lan: All of Brother Fan’s elves like him so much, I’m so envious!

Before long, everyone discovered that the once dilapidated gym had somehow become the pinnacle of two worlds, and even traces of mythical beasts could be seen lurking within the gym from time to time...

Ji Ran traveled to the Collapse World. In this world, which was extremely hostile to men... well, humans, Ji Ran felt a little panicked. However, after obtaining the [Dungeon System], he felt that his survival might be somewhat guaranteed. However, there were two options for the dungeon. The first was to clear the dungeon alone. This was too difficult, so he skipped it. Even if one person buffed the player, he still had to skip it! The second option, while the system's buffs would be weakened, would randomly match players with other players. So... Kiana: [Huh? This world actually has so many fun things?] Alicia: [Hehehe, it seems I'm popular elsewhere, too?] Bronya: [Is this a new game? Okay, Bronya accepts the challenge! Watch Bronya clear it with one life!] Raiden Mei: [I'd like to ask, this dungeon allows me to become stronger and control the power of the Herrscher Core by increasing my natural strength, right?] Mei Raiden: [What the hell is this Shenzhou home cooking 300-style dish? (╯‵□′)╯︵┻━┻]
