Even though I'm a Zombie, I don't know what to do. And if I attack a Castle, I lose my entire army, and that's 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. So, does this mean I have to sit in the Castle, build, and accumulate an army? It seems a little unappealing, honestly, but I guess I don't have a choice. Instead of fighting myself to liberate the Castle, I used auto-battle. And the auto-battle left me with only 6 Inquisitors and 79 Halberdiers. And it will be problematic to break through with them because Paladins cannot be built in the Castle. And losing all your Paladins means you are nothing. Not even regeneration can save the Inquisitors. After all, they have less HP than Paladins. This means that Inquisitors will die faster than Paladins.
