Even though I am a Zombie, I don't know what to do. And if I attack the Castle, I lose my entire army, which is very tough. Even for me, it's a bit too much. And now I don't quite understand what to do next. Because without an army, you are nothing. Especially when there are demons ranging from 100 to 500. And I don't know how to kill them. Does this mean I have to sit in the Castle and build up my army? It seems a little unappealing, honestly, but I guess I don't have a choice. So instead of fighting myself to liberate the Castle, I used auto-battle. The auto-battle left me with only 6 Inquisitors and 79 Halberdiers. And it will be problematic to break through with that because you can't build Paladins in the Castle. And losing all your Paladins means you are nothing. Not even regeneration will save the Inquisitors, because they have less HP than the Paladins. This means the Inquisitors will die faster than the Paladins.
