In their eyes, the founding of the Seven Great Domains or, to begin with, Da Qin, was a mistake.
And ultimately, it was Da Qin that destroyed the Seven Countries, and all the Titan bloodlines from those founding countries were eradicated by Da Qin, leaving no descendants to consider a restoration, which is why the only one with the potential for restoration is Qin Hong, who has Da Qin blood flowing through him.
This is also why the 13th Domain targets only Qin Hong.
To this, Qin Hong spoke in confusion, "The Holy King has ordered the Dark Continent Twelve Domains to wage a war to claim the world, why have you only targeted our Da Qin's founding?"
