Sweep function

I finally unlocked the "sweep" function for fast dungeon play. To unlock this sweep function, you need to reach Lv.26 in Guardian Level (the level you increase at the New Guardian Base). I thought it only required the points. However, to upgrade from Lv.25 to Lv.26, you need to satisfy another requirement: Complete Nightmare W3-6 Magic School 5th Floor, 3 Months Ago. I thought "3 months ago" meant the actual time, and I thought I did not complete that nightmare stage. If I complete today, I need to wait 3 more months??? I was wrong. The title for W3-6 was "Magic School 5th Floor, 3 Months Ago".

Now I have access to the "sweep" function. It completes the assigned dungeon play instantly. I like it. I don't know how long it would take to reach Guardian Lv.51 (for awakening dungeon sweep) and Lv. 76 (for evolution dungeon sweep). It will be a long way to go.
