After Xiao Lei dies from overwork while writing his thesis, he transmigrates to another world and is reborn as a treasure-hunting mouse. Dazed and confused, he asks the ultimate question: "Who am I?" The different factions then give him different answers.
Mota, a traveler from another world: A poor, unlucky outsider.
His fellow treasure-hunting mice: Our future leader, the star of our hopes.
The three great civilizations: The culprit responsible for the world's destruction.
The power of erosion: A powerful contaminant that must be eradicated.
The world's consciousness: An insignificant pawn.

When Xiao Lei hurries over to greet someone from his homeland, he calls out the secret code. "Odd changes, even stays the same."
The fellow countryman says, "What does that mean?"
Xiao Lei blinks. "Are you bad at math? Then, 'The sea lies before us.' What's the next line?"
The fellow countryman says, "??"
Xiao Lei scratches his head. "Don't tell me you're a foreigner. Then, 'The harder I work...' What's the rest?"
"So what exactly are you talking about?" the other person asks, confused.
Xiao Lei tears up and demands, "Aren't you from Earth, like me?" Then he discovers that, sure enough, they aren't.
