Yehuji's Adventure in Another World

After his parents died in a bizarre car accident, Yehuji took their relics—two life diamonds made from bone and blood—on a journey to the end of the world. He was supposed to go to the Antarctic continent, but after he lost his footing and fell into the sea, he was carried into an ice wall by a talking polar bear. On the other side of the wall is a completely unfamiliar world: surrounded by a huge ice wall, the earth is flat. There is an ancient empire that has been inherited for more than two thousand years, a city in the sky suspended in the clouds, domestic slaves named after birds, and a young prime minister with golden eyes and silver hair who is about the same age as him. He is drawn into the fate of a family, the rise and fall of an empire, and an ancient secret about the gods.
