His first companion is Mia, a blonde elven maid who checks his every box. After making love to her, Jett gains mana, unlocks legendary powers, learns his duties as Master of the Warden Mansion, and uncovers its hidden secrets.

He never touches her, and even insult her in front of other women, “Si Wan, you are the most disgusting woman in the world.” Facing his ruthlessness, she decides to leave, “Gong Siming, if you don’t love, just let me go.” But he replied dominantly, “Si Wan, of course I love you.” Si Wan is caught in a trance. And he goes on, “I want to love you tenderly every night.”
