In the meantime, Guili's soul has been locked in a seven-star "soul formation" , so that Guili can't lose it while he's away. He's worried that someone will try to sabotage the formation while they're away, so he asks Guili to take off his cloak. He tells Guili that he doesn't really know where he is, but he does know that the girl is the lover of Guili who's on the ground. She came to him for an investigation, so she's not allowed to gossip. They'll go to the city and bring back Guili, but Guili has to pay more for his help. They can follow the red string to the gate of the underworld, and they can use a talisman to find the soul of the dead man. If it's human, they can call the police. The red string was there when the girl entered the city, but she probably cut it off before she left. They should follow the two souls first, since they've probably been led somewhere. They don't notice Guili and the girl, so they'll just have to fight their way out of the city.
