If you're a fan of Legend of Sword and Fairy, if you're a fan of The Legend of the Ancient Sword, or if you're a fan of Hua Qian, I'm sure you'll become a fan of Immortals and Demons, too. What is love, that it makes people pledge their lives to one another? Where does love lead, that it makes people stay together through life and death? Life and death, love and hate, good and evil: in the end, they all come to nothing. Love without resentment, hate without regret. What could be worse in life than holding on to what you shouldn't and giving up what you shouldn't? Since ancient times, passion has left nothing but regret, a regret that will never end.
