In 2035, technology has advanced to the point that virtual reality has permeated every aspect of life. Dawn Project, hailed as the world's most advanced fully immersive VR game, has drawn countless players eager to explore its uncharted virtual world. Mo Han is one of its top players, famous in the game under the ID “Nightfall.”
On this day, Mo Han clears Dawn Project for the hundredth time. The moment he completes the game, blue-violet arcs of electricity burst from the neural-interface headset inside his game pod, their dazzling light reflecting off his stern face. The final boss's holographic projection shatters before his eyes into a flurry of binary snowflakes, scattering like the end of a dream. Mo Han deftly removes his headset, but the next second, his movements suddenly freeze. He stares at the inner wall of the game pod. The water droplets that had collected there at random are now arranged in an impossibly precise pattern, gradually forming a string of numbers: “19990607.”
