Chu Xisheng and Lu Luanti had stayed in the lower level of the cavern for a total of four days.
Actually, they realized something was not quite right on the first day.
The Long Family's search efforts were virtually nonexistent; the three of them roamed below for an entire day and didn't encounter a single person from the Long Family.
The next day, there were still a few Medicine Gatherers sporadically descending from above.
Based on these people's information, not only had the Long Family revoked their 'enter but do not leave' ban, but they had also withdrawn all clan soldiers from the Fire Bone Cave half a day earlier.
However, the two of them suspected that the Long Family was employing a deception to lure the snake out of its hole, intending to tempt them out of the Fire Bone Cave and ambush them outside.
To be completely safe, they stayed inside the cave for four full days before venturing out.
