As she grows, she uncovers her noble heritage and encounters her destined fiancé, a proud young general who looks down upon her. 
But through tough times, they recognize each other and work toward her ultimate goal.

Chapter 165 Book 4 Concubine Su's Intervention

Xian Town had a unique charm that neither Long Hai nor his adjutant, Yong Ji, could ignore.
