Murong Changge, a genius from the Xianxia sect, was framed and reborn in the city, becoming a bullied son-in-law. At the same time, he accidentally activated the twin system, connecting the two worlds of the city and the fairy tale. In the city, he relied on the skills and knowledge provided by the system to help his wife Su Wanqing develop her career and fight against hostile forces such as the Zhao family. In the world of Xianxia, he returned to his sect and fought side by side with his junior sister Lu Qingyao from his previous life, uncovering hidden plots and looking for opportunities for revenge. As his strength increased, he discovered that his death in his previous life was no accident, and that there was a larger conspiracy behind it. In the end, Murong Changge reached the pinnacle of both the city and the fairy world, becoming a veritable God of War, and successfully changed his own destiny.
