Unfinished unlocking tasks: Before unlocking Sumerian conquest, you need to complete a certain number of ordinary, elite or world degradation levels. Only by completing these unlocking tasks can you log in to the game during the opening hours of Sumerian conquest activities, otherwise you will not be able to enter the activities.
Not logged in during the activity time: Sumeru conquest has a specific opening time, and you need to log in to the game during this time to enter the activity. Please pay attention to the activity time prompt in the game announcement and participate according to the time.
Incorrect activity field input: after the activity starts, you need to enter the activity field through the activity icon on the left side of the main interface. Please make sure that you clicked the icon correctly and entered the correct activity field.
If the above three steps are confirmed, but you still can't enter the field of Sumeru conquest, it is recommended to seek help from the game customer service or the official forum.
