In the thirty-fifth year of Wanli in the capital, Yu Ling, a homeless and unregistered youth, struggled to survive at the bottom of society alongside his sworn brother Xiao Laohu, getting by on begging and theft while enduring years of oppression and humiliation. By a twist of fate, the two accidentally obtained a Jinyiwei waist token, and a fatal disaster suddenly descended, entangling them in the power struggle between the Jinyiwei and the Eastern Depot. At a life-or-death moment, Xiao Laohu chose to throw himself into the Eastern Depot to carve out a path to survival, forcing the sworn brothers into a heartbreaking farewell. Hanging by a thread, Yu Ling was fortunately rescued by retired military officer Yu Yuanwai and brought back to his residence to be settled. The youngest daughter in the manor, Menmen, stubbornly believed that Yu Ling was her long-lost older brother from her dreams.
