Red Dust Immortal and Infinite Red Dust

A young man who had traveled to ancient times had survived the Untainted Land, watched the rise and fall of the Witches and Demons, the establishment of the Heavenly Court, the ascension of the Gods, and the rise and fall of the mortal world. When he finally got married to the Heavenly Immortal Couple, he was "betrayed" by her and sealed in a dimensional island by a mighty person.

A peerless island drifting across the oceans. If a survivor of a shipwreck a thousand years later were to become a thousand-year visitor when the seal of a certain mighty person was lifted after his death, a young girl who escaped from the disaster would encounter a mysterious man on the island. The man would help her out of danger, and she would help the man leave the island and return to the bustling city together. A few days later, in another city, a teenager who had been missing for half a month returned home, and all kinds of strange things happened.

There are four volumes in this book. The first volume is The Homecoming Boy from the Unparalleled Desert Island (Lichen, who had traveled to the Wilderness and lived until now, was sealed on the island. Later, the seal was lifted and he received help to return to the time before he traveled.)
