"Why doctors can command as soon as they wake up!" "Because they once stayed in the border city." "Why know so much about firearms!" "Because I have broken the bridge of my nose."

"Then why run away!" "Because I am not a Doctor Master Commander!" ps1: Comprehensive comics, infinite, The beginning of Game Life Zero, follow the volume name. ps2: Talk to you, there is absolutely no disease this time!
