What's going on with the "Modor Empire"?

Mu Continent, also translated as Mu Continent, is a land that exists in legend.

This landmass occupies most of the South Pacific: starting from Tahiti in the south, Hawaii in the north, Easter Island in the east, and the Mariana Islands in the west. It is about 8,000 kilometers long from east to west and about 8,000 kilometers wide from north to south. 5,000 kilometers, an area equivalent to the combined area of ??North and South America. The residents of the current Polynesian Islands, Melanesian Islands, and Micronesian Islands are said to be descendants of immigrants from the Mu mainland. These people are said to have lived on this continent 12,000 years ago. The people of Mu continent are highly civilized, and they have achieved communication with alien planets. Some of the unexplainable phenomena in our human civilization today all come from the civilization of the Mu continent.

Atlantis, the legendary ancient utopia, was nothing more than a once prosperous empire on the continent of Mu.
