Trench Crusade: I Am the King

[Trench Crusade] + [Conquest] + [Partially Developed Worldbuilding] + [Steam] + [Middle Ages] + [Loyalty] As fanatical religious wars sweep across Europe, as the Crusaders on their eastern expedition capture Jerusalem, a deceived knight quietly opens a gateway to Hell. Thus begins a demon war that will rage for eight hundred years. Wu Lin, who soul-transmigrates into the king of a small country in the medieval Mediterranean, doesn’t see it that way. Since you demons are so powerful, then come and face the trial of absolute loyalty from mere mortals. One day, the double-headed eagle flag, symbol of the human empire, will fly everywhere… across the mortal realm and every corner of Hell. Of course, that is, if Wu Lin can survive the demons’ relentless attacks.
