The cow knight in Cow Castle will be the only one who will ensure the viability of the kingdom. First you need to focus on building a lock, and then on its constantly improvement. You have to build a sawmill, as well as a stone processing workshop. Cut the trees, get stones and strengthen the lock. Inevitably an attack from neighbors, they have long been looking at the fat, full of resources of the earth of your kingdom. We will have to run in order to get resources and build new workshops in order to expand production and develop products that will even more powerfully strengthen the lock in Cow Castle.
