The Demon Lord tells Hou Chi about his younger sister and how she makes him stronger due to having truly protected someone, whereas Hou Chi remains secluded within his home in order to cultivate. This confuses him as he has been secluded since he was a child but he is determined to find out what a younger sister is and get one of his own. Shi Xia lost her brother a year ago when he disappeared on her birthday, but on the day of her speech in order to obtain a national scholarship she receives a phone call telling her that they know the whereabouts of her brother. When going out to look for her brother she is suddenly sucked into a puddle and finds herself in Hou Chi's pool for cultivation where she grabs his robes in order to clime up. Confused on how she managed to get through Yuhua Sect's enclosed ward without powers, he begins to question her and finds out that she is a younger sister. When trying to satisfy Shi Xia with food, we are introduced to Bi Hong, Hou Chi's only childhood friend. (Source: Itscelina on MDL)
