In her previous life, Nan Lianzhi gave her heart to the wrong person. Her family was destroyed, her sect was wiped out, and the one she loved threw her into the Linglong Tower, where she was forced to keep company with evil spirits day after day. She earned herself a reputation as a demoness. It was a bad reputation, but at least she had a good time. That didn’t last long. In the end, the one she loved stabbed her to death... And so the demoness who had once unleashed chaos and bloodshed was reborn as a "troublesome" snake.
