What can it do?

It's just a decoration, not very useful, but it can make your modpack more advanced (maybe).

How to use?

After entering the biome, a message will be displayed in Chinese (I only know how to hard code it). Press B+L to open the progress interface, which will display the biomes you have walked through, the number of biomes you have walked through, and the unlocked milestones.

Compatibility with other mods

It must be compatible.
