Ren Feifan sat in the police station for a while, explained the general situation briefly and then left. Everyone was grateful to Ren Feifan, so they naturally wouldn't cause him any more trouble. Without Ren Feifan, they probably wouldn't have been able to return alive.
As for the disappearance of the ancient tripod, the police were perplexed, but they could not find it onsite.
With such a large ancient tripod, it certainly wasn't carried away by someone. It was probably hidden by the group of dead criminals. Sending out search parties for a few days should find it.
