Minecraft wiki entry for Defeating_an_End_city, associated text: Another way is to mine all the blocks or important blocks of the end city. This can be done if you start from the top of the city and mining down until you reach the bottom. Keep a few shulker boxes at the bottom in case your inventory is full. Using an highly enchanted diamond or netherite pickaxe, preferably with Unbreaking 1-3 or Efficiency 1-5 can help you mine the city quicker and with less pickaxes. In case you accidently fall while mining, keep an water bucket in your hotbar or a potion of slow falling can prevent you from falling and dying. Be careful of shulkers hidden in the city that you didn't kill earlier, as they can give you the levitation effect and cause you to rise high and fall down. Keep on mining until the city is gone.
