It's been three days since they left for Longhu, but cheng still doesn't find any news. They're going to have to say goodbye to cheng, since he's so enthusiastic about finding jiuniang and helping them find her. Hongguiao, the granddaughter of the original owner of the mansion, tells cheng that she's from the descendants of the old man. She's waiting for her to come to Longhu for 26 years, since her grandmother passed away. She says that she inherited her grandmother's will when her great-grandmother died, so she can stay at the mansion for the rest of her life. She also says that cheng is a good man, and that he saved her from being killed by liangyi back in the day. Worried that he might be unreliable, she says that the secret of the wooden box has been kept by the family for a hundred years, and now that her grandmother has died, the box is safe for her. She asks her parents if they've seen the box, and they say that they have. They also say that there's a pattern on the box's pendant, which reminds them of the blade they're wearing. They don't know what to do with the pendant, since it's clearly a taiyi blade, but they do know that the blade is in the box.
