No matter how she looked at it, it was hard to blame Ryu for it. She was the one who had said she was just fine with it, but now that her standing had changed and she overlooked the world, it was a lot harder to accept.
And she knew that this wasn't just a matter of Ryu's love life. If that was all it was, her reaction would be far more petty and less… hurtful.
In the world of cultivation, it was only natural for powerful men to have multiple wives due to the difference between Primordial Yins and Yangs.
Men benefitted from having multiple women, and promiscuous women, except in rare cases, were hurt instead.
The Martial Gods were a clear example of this exception. Their women were often extremely promiscuous, and they were equally as powerful.
But obviously, Ailsa didn't fall into such a category.
