Receiving a riddle from Xiao YuRin was like a thousand of needles piercing YuYan's mind. YuYan can't help thinking why does it have to be this way. It is not that she is not good with it, but it was confusing. Therefore, YuYan tried to contemplate in her thoughts but she can't help feeling irritated after not getting a response from Xiao YuRin. She suddenly blurted out. "What it has to do with birthmark? We are not the only one who has birthmarks.. All eight of us has birthmarks.." YuYan lowered her head while she tried to think until she finally realize. "Hang on… Only me and big brother Yun has different birthmarks, then you and the others were the same.." This is true. The entire siblings have birthmarks. The same six pointed star birthmark on their left chest, but only YuYan and Xiao FengYun has a different birthmarks. "Mine has both six pointed star and crescent moon, while big brother Yun only has the crescent moon.." YuYan uttered while trying to remember, making her more confuse about the connections. Then, YuYan raised her head and looked at Xiao YuRin who was just staring at her and suddenly remembered when Xiao XiRan came back. Xiao XiRan's black eyes have turned into scarlet, and not just that, a six pointed star appeared in his pupil. It was when she abruptly lifted Xiao XiRan's shirt to reveal his faded birthmark located on his left chest. The same mark in his pupil, a six pointed star. (Chapter 433) As she remember, their birthmarks only appears in their eyes whenever they reveal their real eyes and real power that has been hidden the whole time. Despite this knowledge and experiences, only YuYan doesn't know if her own birthmark appears on her pupil when she was in the same state. Although she had seen it through her brothers when they were still young, YuYan never thought about herself at that time. She never asked about it as well. Now she wondered whether her eyes also changes into scarlet and her birthmark would appear. Too bad she can't remember or maybe she doesn't have that memory? Therefore, YuYan blinked twice while looking at her brother and slowly contemplated, faintly mumbling. "But this only happens when you are using your element." "The eyes will change into scarlet and the birthmark appears, but does that happen to me too?" YuYan asked while tilting her head in curiosity. YuYan did not wait for Xiao YuRin to answer though. She looked down on the floor while thinking of the possibilities. "Is this the reason why mommy and daddy keeps on telling us not show our element?" She mumbled.Thinking about any possible connection with their birthmarks, YuYan remembered something, making her frown after all, it made her feel more confused. 'What about Ruegen? His eyes also turn into scarlet with a six pointed star in his pupil, but he has no birthmark..' YuYan asked herself. She has no plan on letting Xiao YuRin know about it since she promised Ruegen that it was a secret. With all the questions popping on YuYan's mind, she has the feeling of wanting to slam her head on the wall to stop making her feel more confused. But of course, even if she did knock her head on the wall, it won't do any good. She's not stupid to do it for real. YuYan closes her eyes and took a deep breath to calm her mind. It won't end well if she thinks of the other things without solving the current question she has in mind. Therefore, YuYan decided to focus about the riddle given by Xiao YuRin.
