By the time the higher-ups finally ordered for everybody to return, it was already 10:30 in the morning. The forensics departments had dug out numerous sets of human bones that night. Due to the bones being buried deeply within the rocks, and completely scattered, not to mention the water build up, the search job had been extremely difficult.
At the moment, the squads outside were gradually leaving, but Department Leader Wang Fei still made part of the collectors remain on scene to continue working, not leaving any evidence behind if possible.
Zhao Yu heard from Hu Bin that the bones at the scene were scattered and damaged badly. According to the experts, the corpses must have encountered some strong impact. The experienced engineers also mentioned that the cave clearly had evidence of an explosion! It was very possible that this tunnel collapse had been caused intentionally.
