Code Name: Yuan

Late at night, a man was running anxiously towards a lighted place, as if there was something scary in the darkness. The next moment, a knife with a strange green light cut his neck. "It's done, call it a day!" "Can you take off the green fluorescent strip on the knife? It will reveal your whereabouts..." "Sister, you don't understand, this is so handsome!" Under the bright neon, there are dangers and opportunities; Above the bright lights, not the sun but more lights; We walk in darkness and pursue true light. Our codename is Abyss, because the world has become an abyss. We... Really succeeded, and sunshine returns to the world. But, are we really... Doing it right?
