"The world is so big, there are all kinds of wonders; there are so many things, there is no end."
"World Independent Zone", referred to as "Independent Zone". This is an ultra-modern cyber city cluster floating in the sky, divided into a main city and twelve satellite cities. Directly below him is a vast sea. There was once a huge hole left by the "Independence Zone" when it rose from the ground. As the years passed, it has become an endless sea.
Whenever night falls over the earth, the Independence Zone and the moon light up the night sky together. Therefore, the Independence District is also known as the "Second Moon of the World".
The Independence Zone welcomes all. It accommodates all dreams and delusions, all beauty and evil. As a member of the independent zone, Kacha walks at the intersection of night and morning with secrets in his arms. Is there happiness or bad news ahead? In this incredible city, dreams can invade reality. The days are long, today's tasks are not completed, and the city is still great.
Concept: A city hanging in the sky originally exists to get rid of prejudice and accept everything, but as time goes by, its meaning is constantly changing.
