On a rainy night at the Shen Mansion, the soul-protecting Ying Niang is ordered to guard the orphans of the Shen family, accompanied by the young child A Dou. The barrier undergoes an anomaly, and the traitorous second uncle leads the black-armored soldiers to surround the mansion, framing the Shen family for colluding with the Myriad Demon Gate. Amidst the chaotic battle, someone carries away an infant to break through the encirclement. Ying Niang stays behind alone to block the rear, fights in a beast-like state, and ultimately dies. A Dou, hiding in the cabinet, survives the disaster, finds his dying mother, takes the torn cloth embroidered with the Shen character, and embarks on a solitary journey carrying the unfulfilled wish to find the orphan and the Flame Bone Spear.
