The Blood Castle occupies the entire Crescent Heights, with only around 60,000 troops under its control.
If the Human Federation wished, they could easily snatch Crescent Heights from the hands of the Blood Clan.
But the Human Federation has never done so.
Under pressure, they even signed a peace treaty.
The main reason for this situation was the Red Duke, who defended Crescent Heights.
A ninth-level orange hero was enough to deter everyone from touching Crescent Heights.
It's not that the Human Federation doesn't have the capability to annihilate Crescent Heights, but unless it was absolutely necessary, no one would want to provoke an orange hero.
The Red Duke, who is adept at hunting humans, could single-handedly exterminate the majority of the human leaders.
Even if Fang Hao's undead army could easily break into Crescent Heights,
they still couldn't defeat the Red Duke.
If Rolana hadn't resurrected him, he would have suffered the Red Duke's vengeance.
