Lin Ye is accidentally caught up in a murder case and mistaken for the killer, landing in police custody. His secret, hidden for twenty-one years, that he can understand animals, nearly comes to light.
After clearing his name, he returns home and follows his grandfather’s dying wish, opening a mysterious wooden box that has been sealed away for years and swallowing a strange pill. Overnight, the pill purges his marrow and reshapes his meridians, transforming him from a refined young man and dramatically enhancing his abilities. He also unexpectedly uncovers a family secret: the Dragon Keepers.
He thinks the trouble is over, but the police inform him that the killer has been caught. Lin Ye learns from a cat, however, that the real murderer has a scar on his face, and the person in custody is merely a scapegoat.
His ordinary college life comes to an end. A mysterious bracelet, an ancient bloodline, and the ability to communicate with all things force him into a world he has never known.
And there seems to be more to his origins than that!
