What exactly is civilization? What about more advanced civilization? Have you ever thought about it? In an urban world, everyone pursues light because of light, and thus shines and heats! Under the dazzling light, there will also be extreme "darkness", where terrifying and weird creatures are born, devouring life, and life restricted areas appear! When all life dies, the existence of "light" will be meaningless. In this "civilized" world, the existence of "light" is the right way, and "darkness" needs to be illuminated.
