There comes some more stuff after the endless layers of stone.
And there will be, in future updates, tons more layers to explore.
But for now the max. depth is 6000. So yes, you can dig beyond 3km! :D
Originally we had the concept of battle losses, and leaving troops in the captured country (you know... to keep it captured!). So we wanted the full number of troops to be somewhat overblown since the losses are random. But we are now discussing better ways to handle the balance of troop count vs power. Expect an update in the next few days! Thanks for playing!
