Unbreakable Stone

Unbreakable stone is the default bedrock of the Modernity. It generates at the bottom of the Modernity to prevent the player from falling from the world. Just like regular bedrock, modern bedrock cannot be broken in survival. However, a bug allowed modern bedrock to be pushed or pulled by a piston. Therefore, players were able to access the void by pulling modern bedrock up with a piston, and then moving it sideways so that an entrance to the void appears.

Unbreakable stone can be broken in creative. When broken by a command, modern bedrock will drop nothing.

Generation
At y-level 4 and below, unbreakable stone will generate. Here, the y coordinate determines the chance that an unbreakable stone block will generate. At y-level 0, there is always an unbreakable stone block.

Trivia
