I'm not a theatre god

After a red meteor streaked across the sky, human civilization came to a standstill. From that day on, people could no longer build a rocket, a nuclear bomb, an airplane, or a car... The pyramid of civilization built up by modern science suddenly collapsed, and the disaster was far more than that. The gray world descends with the red meteor, like a ghostly reflection behind a mirror, dragging the civilized world into the abyss of disorder little by little. In this era, human life is as small as dust; in this era, human beings are as bright as stars. The building is about to collapse, and someone sees an actor standing on top of the ruins of civilization, red as blood, laughing and crying at times, the curtain of the times.
