Lin Zhiye, young master of the Demon Cult, had guarded the formation on Demon Mountain for eighteen years. Her daily routine was staring at the mist and daydreaming, and her one wish was to escape and see what the immortal sects looked like.
Disguised as a lowly servant, she sneaked into the Lingxiao Immortal Sect, only to run into Shu Zekai, the sect disciple who took everything most seriously. He chased her to spar with him, while she dodged him and slacked off. Their scabbards sparked during a practice bout, and he caught her red-handed when she tried to sneak away. Their feelings quietly blossomed amid all the teasing and laughter.
The day her identity was exposed, she hurried back to Demon Mountain overnight, thinking that from then on they would be separated by the divide between immortals and demons. But three days later, Shu Zekai stood at the entrance to Demon Mountain with his sword on his back and lied without batting an eye: "I'm bad with directions. I took a wrong turn."
Immortal sect disciples fear demonic energy, yet he hangs around Demon Mountain every day for a meal. The Demon Cult's young master follows the rules, yet keeps making exceptions for him. When the serene immortal sect meets the lively bustle of Demon Mountain, which of them will be the first to give in to this cross-faction romance?
