Spoiler I've caught up with the latest chapters of ATG. In one of the recent chapters, XQ destroyed BPS and effectively "kill" Yun Che's entire family. Is there any information from Mars that states why she did what she did or is this just one of those "i killed your entire family but not really to make you stronger" scenario? I think she actually killed Yun Che's family. Why? She has inherited her predecessor's memories now so she's not the same anymore. She had probably seen plenty of drama, suffering and all of that shenanigans. She didn't want BPS and Yun Che's family to suffer at the hands of the others so she destroyed it, to end BPS's suffering. She knew she can't save them so she ended their suffering by destroying it. And I think she really, really means it when she said she wanted to kill Yun Che, too. He had shown his devil powers now so she had to follow the footsteps of her predecessors and kill Yun Che.
