Princess Ceni and Ma Jiang talked for a few minutes before parting ways on good terms. Since neither of their interests overlapped there was no reason to be aggressive.
Ma Jiang simply wanted to help out of the goodness of her heart and Princess Ceni's motives were entirely selfish when it came to Hao Xuan.
For the next three days Princess Ceni tried her best to get to Hao Xuan but the grand priestess forbade anyone from meeting him. She knew exactly where Hao Xuan was being kept since their connection was stronger than ever but she also knew that there was no way to get to him without picking a fight with many of these people.
Only Henrik was allowed to visit him just once on Princess Ceni's incessant urging to see if he was okay.
With her newly awakened bloodline Princess Ceni could have easily fought her way through but chose to keep a low profile. It was better to 'act a fool' until such a time as her real strength was needed.
