A fantasy country in the West. In the corner of the sky, there is a city in the sky. The sky there is as blue as ink, and the clouds there are incredibly white. There is no sadness there because the sun warms your heart. Everyone was happy until the new city lord Wei Liqi took office. She covered the sun and the world became dark. No more beautiful flowers bloom, no more color and light, no more happiness. And all of this is just for a reason as small as dust.
