In an attempt to save the captive Butterfly Slaves, Ling Chang Feng enters the prison cell to assess the condition of the slaves who were fed the black peonies soup. At that very moment, black peony petals drift throughout the city, and when inhaled by the imprisoned slaves, they become restless and eventually turn to ashes. Tang Qian Yue, at this moment, also exhibits peculiar symptoms.
Ling Changfeng is an honourable general and has been in a passionate marriage with his wife for the past 3 years. However, a strange disturbance hits their city on their third anniversary, and "madmen" run wild in the town, attacking innocent citizens violently. Ling Changfeng leaves his wife behind to protect the people but when he returns, finds that his wife has been infected by this phenomenon. He refuses to reveal this as he knows that anyone who turns mad will be killed. He keeps her by his side in secret while trying to solve the cause of this frightful phenomenon.
