Easier Gunpowder [FABRIC]
This is a modification specifically designed for Fabric and incompatible with Forge. Its operation requires the installation of the Anvil Crushing Recipes mod.
With this mod, you can obtain gunpowder through an alternative method without building a creeper farm. The process is designed to be logical yet straightforward enough to execute.

The first step involves creating a charcoal block. Arrange nine pieces of charcoal in the shape of a standard block.

Next, place the obtained charcoal block under an anvil and make it fall. Tip: to avoid damaging the anvil too much, limit the falling height to one block.

After the anvil falls, collect the result - you'll get one to two units of crushed charcoal.

As the next step, place the obtained crushed charcoal in water. Within a short time, it will transform into mill cake.

Leave the mass to dry for about 10 seconds, after which it will turn into two units of gunpowder.
As a result of the entire process, the nine initial units of charcoal are converted into two or four units of gunpowder, depending on the amount of crushed charcoal obtained.
