His father disappeared ten years ago, leaving behind only an old blue-covered book. Shen Yan, a tombstone restoration craftsman, is transported to another world because of a single tombstone. There, martial artists possess blood and energy powerful enough to reach the divine, while returning entities knock on doors wearing the faces of the deceased. He can retrace another person's entire life and master the martial arts of those who came before him, but he cannot borrow anyone else's life. From a humble tombstone craftsman to an unrivaled master, everyone in the world seeks to cross the Heavenly Gate. But the path Shen Yan must take lies beyond the Heavenly Gate.
