Edds' VeinCapitator Add-on 1.21+

Do you want to break trees with one hit? This feature is, of course, available to Minecraft users. Even in Creative Mode, you can't break an entire tree at once, but with the mod Edds' VeinCapitator, you can. Just break one block of wood, and the entire trunk will drop as loot. This functionality will also work with ore veins.

To use this add-on, simply press the crouch button and start breaking a block. If you want to use the tree-breaking and ore-mining functions separately, you can change this in the settings.
