In Panshi Village on the East China Sea, the wealthy Ye family and the bandits entrenched on Lingfeng Mountain have been locked in a blood feud for a hundred years. Fate takes an unexpected turn when Ye Mingyu, daughter of the Ye family, and Zhao Qingfeng, the mountain stronghold's third-in-command known as “Cloud-Piercing Arrow,” meet by chance and fall for each other. But when their identities are exposed, tensions between their families flare into an even deeper conflict.
In 1937, the flames of war reach their doorstep. Japanese troops trample the peace of the village, seize the Ye residence as a stronghold, and secretly build an airfield on Lingfeng Mountain while conducting inhuman biological weapons research.

The survivors, Ye Mingyu, Zhao Qingfeng, and Ye Shouwen, the third son of the Ye family, carry Panshi's resilience and the fallen's legacy with them as they resolutely leave the ruins and join the tide of national resistance.
