The Gold Queen

Minseo, betrayed by her adoptive family, friends, and lover, loses her life and is reincarnated as Princess Helia of the Arsene Kingdom.
In her reincarnated world, she is stripped of her royal command through a plot and imprisoned in Daisy Palace.
But determined to no longer be subjected to this abuse, she steadily builds her power.
She establishes a merchant group, forges a connection with the Magic Tower, and expands her business. Eight years later, she reveals herself...
This is the story of Helia, who, with both money and power, becomes the Munchkin Empress, unifying the continent.
