Cleaning up skeletons was a time-consuming task. Glancing at your left hand to check the time, you turned to Hu Qing and Xian Qianling and said, "These people must be the victims of Xu Minjiao and Xu Tonghua, originally buried under the soil. The rain caused the mountain slope's mud to collapse, exposing their skeletons. If it were just the resentful qi of a single skeleton, it wouldn't be enough to affect such a large area, but with so many, the collective resentful qi lingered, gathered by the stream into the reservoir, and then entering the village. The villagers drinking the mountain water tainted with different degrees of resentful qi naturally showed such conditions."
"What should we do next?" Xian Qianling asked.
After some thought, you said, "Retrieve all the skeletons from this place, identify them and the grudge between the Xu sisters, then take revenge for them—that should do it."
