Ember: Reverberation

Except for the initial civilization, subsequent civilizations grew from the ashes of the previous civilization. The inheritance of mankind is also that the pioneers burn themselves and the doers move towards the future. The darkness below the tall building echoes the brilliance of the stars in the sky. The candles that are running out of time are burned out, dedicate yourself, and light the next candle; the extremely sharp blade sharpens the blade, breaks itself, and forges the next magic weapon.
