How to Stop the Male Lead from Going Mad

Lu Qing transmigrates into a book. The male lead is deeply devoted, but the female lead is heartless. She not only breaks off their engagement, she also drives a sword into his chest. When he wakes, he turns dark and becomes a madman who kills anyone who stands in his way, god or Buddha alike. Well, she transmigrated, so be it. But Lu Qing feels like she needs to shout out a missing-person notice to the whole book: Male lead! We're already in the middle of the story! The Taoist temple where we were supposed to fall in love burned down early! I even beat the monsters you were meant to fight! Where on earth are you?! What happened to your devotion? What happened to your promise to love only me? Get over here already!
