[Something is not working in my mod]

So i'm making a mod that removes water in the range of (100 x 100 x 100)

But the code I'm using doesn't seem to work

Minecraft version is 1.7.10 and I'm using the newest mcreator for Minecraft 1.7.10

 

This is the custom code it runs when it clicks a water block

for(int aaaa = i - 50; aaaa <= i + 50; aaaa++){
	for(int bbbb = j - 50; bbbb <= j + 50; bbbb++){
		for(int cccc = k - 50; cccc <= k + 50; cccc++){
			if(world.getBlock(aaaa, bbbb, cccc) == Blocks.water || world.getBlock(aaaa, bbbb, cccc) == Blocks.flowing_water){
				world.setBlock(aaaa, bbbb, cccc, Blocks.air);
			}
		}
	}
}

 

it gives me no error but its simply not working

 

please give my advice about what I'm doing wrong.
