Ye Jingcheng landed beside the hole and studied it closely.
He pinched up some black-red grit and examined it for a long while, then took out a treasure mirror.
This treasure mirror could trace back scenes from not too long ago.
It was useless against cultivators; they would use fire-attribute spells to sweep away the lingering spiritual-light imprints, making any tracing impossible.
