If nothing unexpected happens, the so-called Middle Earth by Vivian is most likely the Earth Immortal Realm mentioned by Chen Min.
Because Vivian's description and Chen Min's description have many similar points in terms of terrain.
The Earth Immortal Realm is a planet several times larger than Earth.
On this planet, there are only two continents, and the rest are all oceans.
These two continents face each other across the sea, and in between them is a large island.
This large island is the only safe transit point between the two continents.
It is on this island that Vivian has seen those sword-flying Taoist cultivators.
And Ning Fan once heard Chen Min mention that many barbarians live on the other continent.
Now hearing Vivian say this, Ning Fan immediately understood that the "barbarians" mentioned by Chen Min were clearly the blonde, blue-eyed residents of Middle Earth.
