My disbelief is failing to be suspended now. They are standing there, talking for like half a minute, Jelly and hero are capable of running extremely fast (especially the hero as seen in previous chapter when he caught falling plates).
Why can't they just run straight at the guy controlling the monsters and decapitate him in a second? He isn't being protected, he isn't far behind monsters, he's not super human. Just kill him and it will be over. Why do they HAVE to defeat the dragon and wolves first.
