I, the Collapsed, the Death Squad

After an unexpected death, the lazy captain Dong Moxuan finds himself in a Honkai-era world. Originally intending to continue his duties as captain, he discovers he's become a suicide soldier. So, Dong Moxuan decides… "I'm not human anymore, Valkyries! I'll become the King of Suicide Soldiers and reign supreme!" Then… "Oh, really?" Looking at the girl pointing a gun at him, Dong Moxuan disdainfully declares… "Don't kill me, I'm really a good suicide soldier!!!" PS1: Harem story, the protagonist is male. If you don't like it, please don't hurt the story. PS2: Don't worry about the protagonist being male; there will be an explanation later.
