Beast of Shackles

Have you ever believed in myths? Have you ever imagined the other side of the world? The world is a cube placed on an invisible table. An observer can see at most three sides and at least one. What is seen is "knowable", what is not seen is "unknown", and the hidden truth fluctuates in the "two-sixths" range - it exists in the embers of myths, strange stories in the city, and corners where people tell stories but no one believes them. But what if someone comes from another cube? Who will be the archivist and night watchman for this "two-sixths"? By recording and then changing the viewing angle, can the six sides of the cube be truly pieced together? How will a "wrong" observer disturb and redefine the "knowable" and "unknown" of this world? Lu Xian opened the book: "My mission is so noble... So can I add more money?" "Yes," new words appeared on the page, "but you may not really know the price yet."
