Fluid breaking Blocks

Ight, this may have been asked before but I couldn't find anything that gives a more brief explanation, im trying to create a liquid that destroys any block that come to contact with it (Im including the non-source block breaking blocks too). I'm pretty new to modding and don't know much yet so does anyone have a detailed explanation of what to actually do? I know it probably has to do with When neighbour block changes or update tick but it doesn't seem to be what im exactly looking for. Any help is appreciated
