Genshin Impact's Three Realm Gateway Offerings event is probably the most player-friendly limited event we've had to date. There's no confusing puzzles like Dante's labyrinth mazes and all the event treasure chests are marked on the map already. Here's all you need to know about the Bunkoku Enigma and the Three Realm Gateway Offerings event parts two and three.
As mentioned previously, both the new limited event resources you need to gather--Aphotium Ore and Tokoyo Legumes--as well as treasure chests, are marked clearly on the minimap, which is quite different from the Golden Archipelago limited event.
The basic play process then is to venture out into the open world--collecting minerals and plants necessary for unlocking Towers and opening chests--then going back to the tree and upgrading the Bokuso Box. You'll want to do this consistently in between the primary questline branches (unlocking the Towers) because the Corrosion level increases in new areas. Upgrading the Bokuso Box increases the amount of Corrosion you can withstand. Once you reach level 14 on the Bokuso Box, a new set of chests and challenges will sprout up on the map.
My advice for solving these puzzles: First check which panels can be rotated--some are fixed. Then starting from the first panel the light will hit, determine how it should be oriented and if it should be ice or water in order to reach the next totem. Go one-by-one until you reach the final destination.
The side quest will guide you to three locations to find seven stone slates.
Library: Hit three totems with Electro. Pick up four slates here.Underground Labyrinth: Follow an electro seelie and pick up two slates in the labyrinth.Aboveground Labyrinth: Solve two mirror puzzles to access the underground area. Solve another mirror puzzle once in a new area. Pick up one slate here.

The pattern you want to recreate with the stone slabsUnsolved puzzle.Steps to get to the solution:
Move 1 and 2 up. Move 3 to the left.We know we have to get 6 to the 3's initial position. So move 6 to the left, 4 to the right, 5 down.After solving the puzzle, it's easy from there. You'll end up unlocking an underground area, fighting an enemy, and getting a Luxurious Chest at the end.
My major piece of overall advice is to take the Three Realms Offerings event slow. There are 40 days more until it ends (at the time of writing this guide), so don't feel pressured to clear the entire map in one session.
