VeinMiner Add-on 1.21+

With VeinMiner mod you no longer need to destroy one block after another. You'll reduce your mining time by several times, because when you destroy one block, all the other blocks will fall out at once. This is a very handy feature if you spend a lot of time searching for resources. In addition to ore, you will also drop and experience for each block in Minecraft. If you don't want to waste time on useless work, then use this addition.

Pick up a tool, use crouch and destroy blocks.

The add-on works on everything but ancient debris, even in survival mode. Remember that enchantments to increase loot do not work with this feature.

For smartphones, the author has made a handy feature. As soon as the player sits down and starts destroying the block, a sight will appear. It indicates where you need to point the character's tool for the fast loot function to work.
