This event is available for players above Adventure Rank 12. During this event period, the trader NPC Liben will appear in various locations across Teyvat each day. Once you find him, you can give him the required material for that day, and you will then be able to claim one box.
In version 1.2, Liben will always be in Mondstadt, and every player will get different elemental boxes that contains different rewards. You can click on the present box to see what rewards are available for the available elements. You can also go to other player's world to claim a reward from their Liben instead. Keep in mind that you can only claim a reward once a day, and the attempts are not stored. Not claiming a day will mean that you lose a day's reward.
Additionally, there will be a Mega Box O' Marvels after exchanging for rewards 5 times. The mega box gives Primogems, Hero's Wit, Mystic Enhancement Ore, and Mora.
