The sacrifice to the Mountain God, this was the price the humans paid for the god's protection. It needed a living sacrifice.
It was unclear if other mountain gods demanded the same.
When the earlier arrivals learned of this condition, some fled, seeking the protection of other mountain gods.
Some huddled together for warmth, ensuring they were not forcibly taken as sacrifices.
Others were domineering, wanting to select sacrifices to ensure their own protection.
After the initial disputes, they reached an unspoken agreement. If anyone else arrived before nightfall, that person would be the sacrifice.
Unfortunately, Li Changhe and Xiao Nan were the last to arrive.
They became the chosen sacrifices in the eyes of the others.
As for making Li Changhe let go of Xiao Nan, it was simply a plan to deal with the man first, keeping the girl as a backup sacrifice while also satisfying their lust.
