The first second you come across on the 4th day of the Mimi Tomo event at Genshin Impact is the thoughtful Hilichurl. It has a Mutual Exchange task for you, which means that it is looking for a specific item, and if you can give it to it, it will give you some information you need. Two requests to exchange one day are the first event, so it’s interesting.
The good news for players is that they have a Handy Handbook of Hilichurlian that they can use to find the various phrases that the Hilichurli will use. Hilichurl will use the phrase “Lata Boya Sada” and we will have to figure out what he needs from us.
Lata Boya actually means color and means blue. Set on the other hand means hard or hard. So we can figure out that Hilchurl wants something hard and blue. Interacting with them will recall your inventory and you can select and place them. We went with Crystal Chunk, which meets both requirements. Then he will give you the place and time to find the Unusual Hilichurl on the 4th day.
Players can open the Handy Handbook of Hilichurlian at any time by going to the Mimi Tomo section of the event menu and clicking on the Handbook prompt button at the bottom of the event description. There are quite a few Hilichurlian phrases, but fortunately it’s pretty easy to figure out what these little boys are talking about.
