Chen Ping, the Millennium Pill Emperor, was favored by the ancestor of the Mu family when he ascended through a tribulation. In order to repay his kindness, when the ancestor of the Mu family was about to expire, he responded to his call and transformed into a mute son-in-law to protect the Mu family for five years. During this period, everyone in the Mu family regarded Chen Ping as a useless son-in-law and bullied him in every possible way. The eldest daughter of the Mu family, Concubine Mu Luo, was even more mean to him. When the five-year period is approaching, the leader of the Dan Alliance (Chen Ping's disciple) holds a grand gathering of Ten Thousand Dans. Chen Ping secretly helps Concubine Mu Luo refine the Nine-Turn Return to Yang Pill, but Guo Yun takes the credit for it. Concubine Mu Luo not only fails to distinguish right from wrong, but also humiliates Chen Ping. At the Wandan event, Chen Ping showed up to reveal his identity.
