Gawain transmigrated, but his transmigration had a little problem. After floating in the sky of a continent from a different world for hundreds of thousands of years, he thought that he probably needs a body to be considerd a complete transmigrator, however he didn't expect that after managing to get a body with great difficulty, he unexpectedly has to crawl from his coffin, moreover, he has to face two scared ladies that are his great-great-great......... great-granddaughters. As well as a world that it's about to arrive at its era's conclusion.
