When the gear-shaped aurora lights up on the campus dome in the 23rd century, Lin Xiaodong, who is wearing a retro plaid shirt, is being chased by a sweeping robot to "sort garbage." This frozen man who used emojis from 200 years ago to tease girls made a series of jokes on the steampunk future campus: he used the quantum portal as a microwave oven to heat up lunches, taught the AI butler to curse in Zaun dialect, and led the mechanical club to build an old-fashioned arcade machine using a steam engine. But when the shocking conspiracy in the freezing agreement is discovered, when Arya's mechanical heart starts counting down, and when the suspended classroom falls into the neon wasteland, those daily routines that lead to laughter and tears will eventually become a weapon against the doomsday.
