According to one of the сhinese forums
The update this month is as follows:
V0.412
-----------------------------------------------------------------------------------------------------------------
Dungeon
The plot has been fine-tuned.
The difficulty of the dungeon has been reduced.
The hint has become more obvious.
Switching characters is no longer a necessary choice. Now Mengli can pass each level through her own unique method.
Added a new event for Mengli to pick up treasure chests, 10 sets of CG. (CG will be affected by factors such as the durability of clothes, but the plot is the same.)
A new event has been added that allows Mengli to close certain traps. 7 sets of CG.
A new event has been added, which allows Mengli to obtain a small amount of wood elements. 3 CG.
A new type of ground thorns has been added, and if Mengli steps on it, there will be an independent event. 2 CG sheets.
The CG that was not colored last month has been drawn.(2 sheets and 2 sets)
