"Adventure Quest: At the HoYoFair 2"

Various adventurers get projected or teleported from wherever they’re at into MiHoYo HQ. Varin and Charlie are specifically astral projected from their current campaigns and return with the memories of the events but none of the physical fatigue (they did not take rewards). They are outfitted with a bracelet that displays information needed for the current area and minigame, as they hop between various HoYoVerse IPs testing out different modes. They managed to win the first minigame, Teyvat Turboflux Tail-Light Trail, being a team based rally race and capture the objective.

Rewards: 300 gold, 2600 exp
