The ninth stage of the Kanigem Tournaments

Victory is achieved by eliminating the last Hero and capturing the castle, but if there are still caravans or simply free units on the map, there are two options: either kill them all, which is practically impossible unless they are right in front of you, or wait 3 days. After 3 days, victory is achieved automatically, as there are no more enemy Heroes and you have defended your cities... In your case, you just need to wait 3 days... After all, there are still free units left...

Sincerely, Luchik!
