How to light up (unlock) the whole Chasm underground map in Genshin Impact

Genshin Impact players should know that The Chasm's underground section doesn't have a Statue of the Seven to unlock its entire map.

Lighting up the Overworld part is easy, as one just needs to go near Cinnabar Cliff and interact with the Statue of the Seven there.

While there might be nothing like this in the Underground Mines, one can choose to complete quests to light it up. However, it's not just any quest.

You must complete all of the quests in The Chasm Delvers quest series to unlock everything. Individual quests in that series will unlock and light up some parts of the world map.

Completing the necessary quests in Genshin Impact

Players need to complete the following quests to unlock the whole Chasm underground map (in order):

1. Chasm Spelunkers
2. First Miasmic Contact
3. Meeting New People... and Foiling Some Bandits
4. The Heavenly Stone's Debris
5. Perils in the Dark
6. Wherefore Did the Spiritstone Descend?

There is no shortcut for Travelers to unlock the full map quicker. One might as well get ready to grind through an entire quest series as soon as possible if they want to see the Underground Mines without darkness in Genshin Impact.

It's worth noting that one can access certain parts of the Underground Mines without lighting it up. However, it's highly advisable to unlock the entire map as soon as possible for one's convenience. Otherwise, it will be a hassle to explore this area.
