Whoosh!
The black hoverboard soared into the air, racing on the knife-straight, smooth facade of the skyscraper.
On the hoverboard was a girl wearing a loose hoodie, her delicate chin visible beneath the shadow of the hood. Her eyes were fixed on the cobblestone path that faintly appeared on the glass curtain wall of the building, the wind whistling past her ears, shaking the rim of her hood violently.
Suddenly, a silver blade swooped up from beneath her feet. The hoverboard narrowly dodged it, but the moment the girl in the hoodie got distracted, a tall, dark shadow flashed past her. Looking up in surprise, she only saw a man wearing a black tank top, his well-defined muscles moving fluidly as he sprinted on the side of the high-rise.
The man bared his teeth, defying gravity as he ran wildly on the facade of the skyscraper. Unwittingly, he stepped on a hand-drawn, grid-patterned, white-paper landmine sticker.
Boom!
