Merciless Ender Dragon

What? The end?

well that’s where my story ended because after Responing The ender dragon, every thing started as normal as could be, then I went to a tower with a Crystal on it. I managed to get to the top but when I got there... I tried to destroy the Crystal but... I slashed to no avail. The Crystal stayed in its unrighteousness sitting there. Thus I was left with  the enormous task of killing a near immortal dragon.
