The point of this is to kill all of your friends and every animal (Including item frames and paintings since the are enties)
What to put in the first command block: /say Testing World Kill Rate
The second: /say 3
The third: /say 2
The fourth: /say 1
The fifth: /kill @e
(Or /kill @a to just kill the players, not the mobs and entities)
Since every tick mark on a repeater slows the process down by 1 tick, you will want to add 10 tick marks to make the command block command magic happen by the second.
Hopefully you get what I'm saying. Or else your a noob.
So once you flick the switch, this will happen:
I broke the last repeater so I didn't die and lose all the entities in the world, but if I hadn't I and all the entities would have died.
