Heroes' invitations are the stepping stones among nobility.
It's also a way for nobles to challenge each other.
For one to gain a voice, they must have absolute strength.
Otherwise, they can only make compromises.
Back then, the North Palace King bore the sign of eight dragons, so after he slew the old Nine Provinces King, no one in the royal mansion troubled him.
The true reason the North Palace King became an overlord was that when he entered, he broke that bone slab.
People of royal stature would have a bone slab.
It's a symbol of their identity and the only chance in their life to break it and become the Nine Provinces King.
That's why many plan thoroughly before daring to break the bone slab.
But the older one gets, the more timid they become.
It's a fact and a rule.
