Hundred Thousand Great Mountains, entrance to Lost Valley.
Every half month at dusk, it was time for Disciples of the Eight Major Sects to rotate their guard duties, each sect assigned two people, making a total of sixteen guarding the valley.
This had been the rule for many years, and disciples patrolling and guarding the valley would typically find a quiet spot to close their eyes and cultivate.
After all, with so many people watching, it was difficult for even a fly to enter without being noticed, and there was no need for people from different sects to take the risk of sneaking in.
If anyone was most likely to take such a risk, it would be someone from the Heavenly Silkworm Witch Sect.
At this moment, a black figure had already quietly infiltrated near the valley's entrance, concealing his form in the miasma and fog.
The figure in black silently calculated the time, less than half an incense stick of time remained before the guards would rotate.
