Storage ring can suck in anything?
I was just contemplating about all the times the mc gets stuck somewhere with no way out for days or longer even, sometimes alone or with other people. Yeah shure, often they already don't need to eat and stuff, so no problem, but! as always in novels they neglect to basic necessity of getting rid of the food they eat! But then it hit me, dimensional storage bags /rings. Can you just directly suck stuff out of you bowels /bladder?
