I, Seele, Are Making Trouble in the Collapsed World

As a cute newcomer, it is very good for Amway to play Honkai 3 mobile game. The girls in it are all beautiful, they speak well, and they look good. I fell in love with this game at first sight.
As a newbie with good luck, when Twin Xier was UP, she completed the graduation of S Xier with four rounds of precision, which made me like this game even more.
Obviously it's a double happiness, and it should become very good if they are together, but why does it become like this?
I, unexpectedly, traveled to Honkai 3 and became Xier! !
It's not that the original role has been replaced, but it is completely an independent Xier who was airborne in!
Hey!
I have never played the game Honkai Impact 3 at all, and I have no idea what the plot in this game is!
Who can tell me why Bronya looks at me like that, who are you! ?
Who can tell me why this guy named Kiana keeps pestering me every day? !
Who can tell me who Otto is? !
In this dark, cold, and ruthless collapsed world, only the salted fish module, which has no novice tutorials at all, can bring me a little warmth.
