Unbeknownst to them, Li Xu and his companions had already spent two nights in this replica scene.
The first night was in the small building by the riverbank. The situation that night was extremely dangerous. If Li Xu hadn't taken great risks to move the monsters' corpses out of their hiding place and staged it to look like an accidental fall from a tree, the mission might have already failed. Amidst such a horde of monsters, even someone with extraordinary abilities would not have escaped being devoured.
Hiding on the top floor of the small building was like being on an isolated island in the vast ocean. Everyone was terrified, passing the night in such anxiety that they hardly dared to breathe too loudly.
