"Who are you?"
"A janitor cleans, assembles customers, cleans up traces, and restores the scene..."
"Who are you?"
"A detective in a small town, a dancer in a tavern, an assassin in the dark, a general on the front lines... And of course, a loyal servant of the people."
"Who are you anyway?"
"I, Zuo Ling, am a player in the apocalyptic train game. I drive a train from the starting station to the far-off destination. I participate in games on every platform along the way. I get points, upgrade, survive, and then gain insight into the truth of the apocalypse and save her world."
"Why do you have so many identities?"
"Because, I have a random identity card at the beginning."
