Honkai Impact 3rd: You Can't Be Serious? This Is the Previous Era

Good news: I transmigrated.

Bad news: I ended up in the Previous Era of Honkai Impact 3rd.

“Wait, you’re saying this is the world of Honkai Impact 3rd? Is there still any chance I can go back?” the desperate boy suddenly shouted.

“I’m sorry, but you can’t go back. You have to accept your mission.” A hoarse voice echoed beside the desperate boy’s head.

Oh, well. Since I’m here, I might as well see if I can change their fate.

(This is my first time writing a book, so please forgive me if it isn’t very good.)
