Idle Conquest

Greetings generals! I am Queen Catherine von Conqueror the Fourth and I will conquer the world. Of course no conquering is successful without a good general. You will be my general! I-I mean I just think you will do a good job and serve my country Touria well so don’t get the wrong idea!
The other countries have strong armies and well trained troops. But I do not care about that because I have a secret that they do not have fufufu! Dark knights will join Touria and I need your help to make them grow! Soon, our dark knight armies will overrun their pathetic countries and Touria will rule the world!
Will you join Touria and help me conquer the world? You will rule the world together with me!
Your goal is to conquer the world by buying as much as you can, gaining as many dark knights as you can and resetting so that they join your nation forever!
Do you have what it takes to rule the world with Queen Catherine?
