When Xu Rouguang first entertained that simple request about Fan Yuye, he didn't really think it was because she was a former demon. It must be something about her, but he didn't pry too much into it since he knew his husband so well. However, it did derail his thoughts when he saw him staring at her like he was looking at someone he wanted to hug and hold.
Then, Lai Mingjie said something about him 'figuring it out already' so Xu Rouguang realized it had something to do with the past. However, he really did not think of Emodao's demon sentinels.
When Lai Mingjie accepted Nuwa's powers and awakened his divine core, she signed a contract wherein it was stated that the four demon sentinels who had lost their lives to Youming's schemes were to be reborn without memories and without punishment. Even most demons who helped in the evacuation during the attack were gifted with a conditional pardon.
How wild was it for them to come around now?
