Layoffs, bankruptcy, homelessness... Chen Anan's life collapsed overnight. In order to survive, she was forced to accept a sky-high price commission and step into the extremely rumored "Kirigakure Hot Spring Villa". I thought it was an ordinary haunted house, but unexpectedly, I awakened the Yinglong bloodline that had been dormant for thousands of years, and even met the man who controls everything - Lu Chen.
He is the Lord of Cloud Peak and the key to the mystery of her parents' disappearance. In order to survive and find the truth, she signed a contract and became his exclusive "purifier".
From mutual testing to life and death dependence, when the ancient bloodline awakens, and when the cold heart is warmed by warmth, Chen Anan discovers that this contract based on interests has unknowingly turned into a fate that she cannot escape. Let's see how ordinary programmers join hands with the descendants of the true dragon to break the puzzle, protect the common people, and compose a love song that spans a thousand years.
