Love on the Turquoise Land

Also known as: Mad Blade, Feng Dao

Nie Jiu Luo is a low-key sculptor who is secretly a descendant of the Nanshan (South Mountain) Hunters, an elite unit descended from an army once sent by Qin Shi Huang to seek immortality. Code-named "Mad Blade," she hunts dangerous Earth Fiends while trying to live an ordinary life devoted to her art, but her heritage keeps pulling her back into danger. A chance collision with Yan Tuo, whom she initially mistakes for an Earth Fiend, draws her into a deepening partnership and eventually into an ancient conspiracy involving immortality and a hidden kingdom.

Yan Tuo is the general manager of Roadsound Chemical, publicly a rich second-generation heir adopted by Lin Xi Rou, but privately carrying a blood feud: his birth mother was paralyzed and later died because of Lin Xi Rou's scheming, his birth father died tragically, and his younger sister disappeared without a trace. He sets out to uncover the truth about his adoptive mother's manipulation of his family, and a chance encounter with Nie Jiu Luo pulls him into her hidden world of Earth Fiends and ancient secrets. The two gradually move from suspicion to deep trust and love as they investigate together.
