The Lost World

This is my first time to make a mod, some places are not very mature, .......
Let's talk about the main content of this mod:
This mod adds a new dimension called “The Lost World”, you need to make a specific entrance to enter it, but this dimension is not a very pleasant place, it is full of very dangerous creatures ...... but you can also create new items to face these creatures and challenge the bosses in this mod!
Also, since this mod uses the geckolib plugin, please use the appropriate version of the geckolib plugin when playing!
