In the early 20th century, scientists proposed a shocking theory: there once existed a highly civilized ancient continent in the Pacific, known as Mu. This continent was said to be as large as the combined areas of North and South America, and its inhabitants created a brilliant culture and advanced technology, only to vanish beneath the waves overnight. Scholars have been attempting to unravel the mystery of this enigmatic continent through literature and archaeological discoveries, but many questions remain unanswered to this day.
