The 'friend' she mentioned was her previous incarnation. If it weren't for Yun Luofeng, she wouldn't have become an orphan and been bullied for so many years.
"What did you say?" Wang Haotian turned pale from fright. "That young man actually has such an evil mother? If Yun Chutian were to marry into his family, wouldn't she have to suffer?"
"Xuelian, what should I do? I can't allow Chutian to be cheated into a wolf's lair!"
"Brother," Wang Xuelian smirked and said, "Secretly feed Yun Chutian this medicine and after you've done the deed with her, she will become your wife."
Wang Haotian stared blankly and frowned. "I don't think this is a good idea. Also, Yun Chutian said that she's invulnerable to poison."
"Invulnerable to poison doesn't mean impossible to be poisoned. Moreover, this medicine isn't poison and it'll be effective if used on her." Furthermore, Wang Xuelian completely disbelieved the matter of invulnerability to poison.
