This guide shows the complete walkthrough of the Meeting New People and Foiling Some Bandits world quest in Genshin Impact 2.6, which released on 30th March 2022. You get this quest automatically during the Chasm Spelunkers world quest.
Go to the campsite that has been occupied by Treasure Hoarders
Go to the waypoint marked in the picture below. Then jump down on the east side and glide down to the Treasure Hoarders camp as shown in the pictures below. Clear the Treasure Hoarders in the miner’s camp and then open the cage there to free the prisoner.
Go to the second occupied camp
Now jump down and continue in the south direction to reach the second camp as marked in the picture below. Clear the Treasure Hoarders in the camp and then examine the giant cannon there.
Go to the storehouse in which the cannonballs are stored
From the second camp, go west to reach the storehouse as shown in the pictures below. The storehouse is on the lowest level of the mine, so there is no need to climb on the scaffolding around there. Simply go west to reach the storehouse. On reaching there, a cutscene will start and the quest will be complete.
