The sound of suona played, and the strong men of Yu Family Village hurried towards a nearby valley under the guidance of the Village Chief.
Tian Lin and Elder Ran mingled with the boys from Yu Family Village, following behind the group of adults as they entered the valley.
There was a stream in the valley, which flowed out from a cave deep within the valley.
Tian Lin noticed that from the entrance of the valley, broken iron chains continuously stretched out from the stone walls, hanging between the two sides of the valley.
These iron chains had array patterns engraved on them.
Perhaps a long time ago, the entire valley was set up as a large formation.
But this formation was later destroyed by someone, causing the iron chains to break.
What was the reason for establishing this formation, and who destroyed it?
