Xu Wan married into the Hou Mansion with the intention of living a stable life, but she was threatened one after another by the notorious Zong Jincheng. She immediately raised her knife to fight back, which instantly became famous in the capital. Who would have expected that her parents-in-law would hand over this demon king to her discipline. Everyone is not optimistic about it, but Xu Wan is very capable. Zong Jincheng, who used to be stubborn in the past, has gradually improved and become excellent in both civil and military affairs, shocking both the government and the public.
