Well, there are a lot of world quests that I liked when I was in the early to the mid-game phase of my Genshin Impact journey. Right now, I have a few quests in mind, like the Nine pillars of the peace world quest that requires players to level the statue of seven in the Liyue region to the maximum level. You need to collect stones of remembrance to unlock nine pillars and eventually obtain your first 5-star artifact sets. This Quest is evident in my mind as I got my first 5-star artifact when I was below Adventure rank 45, and the fight was challenging enough to make me change my team composition. Another Quest I liked was The Chi of Guyun quest, which is now called The Chi of Yore. This world quest featured a backstory about the events that happened in the past between Rex Lapis ( Zhongli) and an evil monster. I won't go into the plotline of that world quest here because we already have an excellent guide on it. But, that world quest really has a tough challenge that you have to complete to successfully end the Quest and get rewards from an NPC, Granny Ruoxin. I love how world quest features interesting stories of various NPCs and sometimes relates to past events to shed light on the current world.
