The Archon quest you need to have completed already is “A New Star Approaches” which is in Chapter 1, Act 3, just before Inazuma can be unlocked. You will also need to complete Perils in the Dark quest which is the previous quest in the series of the Chasm delver quests that you can start by talking to either Lan or Xu in Liyue Harbor, and then talking to Muning at The Chasm.
You can start this particular quest in the middle of the Underground Mines map which is in the lower part of The Chasm. There is a path here that leads to the south to the Nameless Ruins where you need to talk to an NPC called Zhiqiong, and follow the path behind him to the camp. Travel west from here through the Glowing Narrows and use the Geo mines to blow up the obstacles in your way. Jump down the tunnel and carry on westwards to find a glowing mushroom here.
You will need to speak with Zhiqiong again and open the gate here using the key which you have obtained during the Perils in the Dark quest. There is a piece of Lumenstone Ore here that you need to pick up. You will need to purify the large crystal which you can achieve by going to five of the glowing red mechanisms nearby and using the Lumenstone gadget to cleanse them. It’s a good idea to upgrade your Lumenstone gadget prior to this. Once you glide to the crystal, it will start the next cutscene.
Now, you will need to face the Ruin Serpent called Haftvad the Worm. The strategy is to use your Lumenstone to destroy the Oozing Concretions which will stun Haftvad. You can recharge it with some yellow crystals nearby with Geo attacks.
