章節 1467: Chapter 1466-the most annoying clue in history

Just as Zhao Yu had been worried about before, the case of the missing exploration team seemed to be in a dead end, with no clues at all.

He read the exploration team's log a few times but did not find anything suspicious.

There were no torn pages, no traces of editing, and the exploration team's work had been normal without any accidents.

In order to make sure that there were no problems, Zhao Yu even checked the latest well that the exploration team had opened, but there was nothing in the well, which was consistent with the exploration log.

According to Zhao Yu's understanding, including the two security guards from tarstan, the twelve exploration team members were all clean and had good backgrounds. They did not have any bad habits, nor had they had any contact with any criminals.
