This creation will slowly give gold when operating it. be carefull.

First you make sure the 2 pistons ar blocking the lower part. then on easy, medium, or ,hard, let the zombie pigmen spawn. make sure you dont fall in with them and then kill it. once you do so dont jump in for you cant get out. instead, either turn it on peacefull or do this fast, switch the lever and go down and get the items. [gold nuggets and rotten flesh]. then leave there and close the pistons.
