In the midst of the blue and purple neon lights, under the gray, metallic sky, it is the frontier of all data, the aftermath of a scientific revolution, also the border of fiction and reality. Metal and flesh, past and future. Here, the virtual world and the physical world exist side by side. It seems like the wall of time is right in front of your eyes. As darkness gradually descends, you must realize, my friend, that we can't survive the darkness with kindness. We must light a fire. (Source: Bilibili, translated)
