Geologist Lu Yao uncovers Ming Dynasty weapons and bones at a landslide site, awakening an ability to see what others cannot. Soon after, he witnesses ghost soldiers in tattered armor marching silently through the night while entranced villagers dig at an ancient burial ground. Family records reveal his ancestor once "eliminated over three hundred bandits," but as Lu Yao delves deeper with the help of a mysterious Taoist, he discovers a truth buried for centuries. These weren't bandits at all. With a bronze bone bell and ancient scripture, Lu Yao must unravel why these souls cannot rest. Their unfinished business isn't about vengeance—it's about something his family has owed them for three hundred years. What sacrifice will it take to put these restless warriors to peace? And what happens when the past refuses to stay buried?
