@Odie: Doing this challenge in less than 13 days is very likely possible, though. If you ever try it again, I'd love to know how fast you managed to do it.
Maybe I will, maybe I will.
It is very tempting...
I have just started another attempt at the Immortal Dynasty though, but trying this challenge again could be a nice change from time to time.
I really enjoy it very much to read everybody's strategies. Thanks for that!
