Invincible Heroes' Great Diplomacy

There is no relaxed and funny daily life, no colorful magic, just knights fighting in the blood, sweat and quagmire, and giant cannons roaring on the battlefield and city walls! (The Goldfinger destiny template is based on the English 3 template, and its skills include diplomacy, leadership, etc. The background of the story is the furry bear of Europa Universalis 4. The protagonist has a stable but reckless character.)
