[6 1] How to do this task of the Demon Master?

Put the mission items near the wall of Hellfire Basin (west of the wall), and then gradually brush some monsters that look like imps, but they are physical attacks. They will attack mission items. You should ensure that the task items will not be damaged by them, and wait until the task items have connectors in all four directions before ordering the task items. This task can also be completed with the dialogue of task items protected by others. It should be noted that the speed of brushing monsters will gradually accelerate, and the number will be more in the end, so the suggested number of players written in the remarks is 2.
