A free mod for Mount & Blade II: Bannerlord, by Shemiroth.
This mod adds an extra speed option to the Better Time mod for Mount & Blade II: Bannerlord. It allows you to fast forward through time.
Once installed, pressing the corresponding button will speed up the game to 12x. And, when you release it it will go back to normal. This is great for when you need to wait for a while in-game and you want to be able to skip the slow parts of the story.
The only thing you need to do is to install this mod into your game.
