Since they were new sisters, and they were on the same side, Xinyan couldn't just sit by and do nothing. Even if it was just for Lin Yi's sake, she had to take good care of Huang xiaotao. The best way was to make Huang xiaotao also become Donghai's disciple. This way, the two would be sisters in the same sect, and no matter what happened, they could face it together.
Moreover, she was the only personal disciple of Donghai's nun, so she would take care of everything. If Huang xiaotao joined them, she believed that she would not suffer any grievances.
Donghai Shanni was already tempted, but she was too embarrassed to argue with Ling Yuanqing and Wei Hebei. However, after hearing Wang Xinyan's words, she made up her mind.
