In the fantasy continent "Land of Fallen Stars", strong men practice with the power of stars. The Pole Star Abyss is an abyss prison where felons are imprisoned.
Mingyi, who appears to be the "Silver Moon Warrior Princess" who has won seven consecutive victories, is actually a secret intelligence officer of the shadow organization who was poisoned while investigating a high-level conspiracy.
Ji Bozai was born as a prisoner in the Polar Star Abyss. He rose to power with his astonishing talent and will, and was burdened with a blood feud and an unspeakable secret.
The poison Mingyi received did not come from the enemy, but was secretly inflicted by the organization she was loyal to in order to test new control drugs; Ji Bozai's true identity is the orphan of a hidden family that was destroyed by the organization many years ago, and his revenge target is Mingyi's superior.
