My ancestors miraculously encountered the floating land that they traveled through and opened a grocery store on it. Their ancestors have been living and selling in it for generations. Going east and west, they will appear in a densely populated but unnoticed small place every once in a while. Wherever they go, the world will rationalize the existence of the grocery store. As an anchor point, you can enter the grocery store at any time. As a new youth in the 21st century, Zhang Xujin, the 19th generation descendant of the grocery store, has begun the journey of choosing his own anchor point.
