The Fox Demon Master Turns Evil

When the straightforward Iron Lady offended her fox demon master with eight hundred schemes up his sleeve.
Sangmo was a straightforward Iron Lady, and after she jumped down from the Heavenly Realm, blinded by ignorance, she mistook someone else for her master. Not only did she kill her master's reincarnation on her wedding day, but she also gifted the Heavenly Book, bestowed upon her by her master, to her enemy.
The moment she was reborn, the aloof master suddenly turned into a petty and mischievous young ghost.
What could she do about it? She had to endure it, since she had done him wrong in her past life, right?
Shen Yanqing intentionally left kiss marks on her neck to mislead others, and Sangmo endured it.
He cast a spell so she could only be hit, and she endured that too.
Shen Yanqing, "Was that wrong?"
Sangmo, "It was wrong."
Shen Yanqing, "Where was it wrong?"
Sangmo, "…"
Shen Yanqing, "Immortal, that's hardly sincere!"
Immortal?
Sangmo was stunned; could it be that Shen Yanqing had also been reborn?
