The third son of the emperor, Gu Mingyuan, was sent to Qingzhou by his father Gu Jinglan when he was five years old. He became a disciple of Jiang Wuyi, a martial arts stranger. His biological mother, Qin Ruling, faked her death and stayed away. Unable to worry about her son, she disguised herself as a man and went to Qingzhou under the pseudonym Lin Er to become his neighbor.
Gu Mingyuan lost his love at a young age and had doubts about Lin Erduo. After all kinds of temptations and speculations, he learned part of the truth, which led him to a wrong conclusion: his mother abandoned her husband and son and eloped with his uncle Chen Guanghua, and his father's neglect of him was all caused by this. They asked the master to accept them as disciples and treat them well, just to compensate.
Chen Guanghua's adopted daughter and Lin Er's apprentice were actually their illegitimate daughter.
He is soft-hearted towards his amiable uncle, helpless towards his guilt-ridden mother, and his weak and incompetent father is even more innocent.
Only his half-sister was the one he tried so hard to get revenge on.
