Zhu Yi Pin, Liu Ruo Xin and the others find Xiao Yuan Zi's body with his heart ripped out by the heart-stealing demon. Zhu Yi Pin notices a red mole at Xiao Yuan Zi's heart. Judging from all the heart-stealing demon's victims, he concludes that the heart-snatching demon targets people whose hearts have a red mole. That reminds him of the little prince who also has a red mole on his heart. He thinks the little prince is the heart-snatching demon's next target and, therefore rushes to the palace for the little prince with Liu Ruo Xin and Chen An An. (Source: Viu)
