The Red Fox did as told and brought back a book. Pu Yanlan flipped it open and saw it was a travel log. Fortunately, the text here bore similarities to their own, so reading it was not difficult for the two of them.
"So this place is called the Hanchen Continent, with twelve states and over two hundred countries..."
The two spent the whole night reading the travel log and finally gained some understanding of this place!
Pu Yanlan really didn't guess wrong; this place is indeed across the sea. At the end of the book, italso introduces the sea on the opposite side, saying that there's a lost continent over there. In ancient times, immortals used Supreme Immortal Power to pull a giant meteorite from the cosmos and placed it within the continent, creating a vast Secret Realm. After the Primeval Wars, the Illusion Sea emerged, severing the connection between the two sides. This separation has lasted for a hundred thousand years!
