Not killing the king is not a question of willingness, but facing the king's suppression, there's only one path to death. Demons who sign contracts can originally be resurrected, but if killed by the king, there's no chance of resurrection.
Moreover, the strength will be severely suppressed when forced to act, making it almost akin to seeking death.
Through the contract, the retreating Succubus transmitted a message to the senior Magician: this Succubus royal family is not directly leading her, but is greatly renowned. Not only is their royal bloodline pure, but they also have the bloodline of a Demigod, perfectly blending two bloodlines together.
The senior Magician finally put away his disdain; while he has many Demon Pets, the Succubus is one of the strongest, though not irreplaceable. He promptly replaced the Succubus with the Demon Queen.
