The rules here are very simple; in fact, anyone who has reached the sixth tier and entered this place is a member of the Dark Web. Those sixth tiers who haven't joined the Dark Web are all outside in Yellow Sand City, to the maximum extent ensuring that secrets are not divulged.
So the task received by the sixth tiers here are mandatory; they need to enter the frontline and fight the frontline forces.
As for the fifth tiers, most of them are not part of the Dark Web, as very few people are recommended to join the Dark Web before reaching the sixth tier. Thus, these fifth tiers are mostly either cleaning up behind the frontline or clearing out Blood Lotus members deep in the rear.
The fourth tiers are absolutely not allowed on the frontline; the most dangerous task for them is joining the fifth tiers in wiping out hidden Blood Lotus members. Of course, managing logistics is their duty. Those who haven't reached the fourth tier are not allowed in this world.
