Yan Xuan, the majestic lord of the underworld, the head of the ten palaces of Yama that rules all ghosts - but he has a fatal weakness: he is afraid of ghosts! (Especially the ones that are ugly, appear suddenly, and die miserably...)
When Yan Xuan used a modern shower for the first time, the water heater suddenly buzzed and vibrated. He thought it was a "water ghost" and was so frightened that he fled through the wall to the living room, wrapped in a bath towel in foam, and knocked over the coffee table. Su Muqing rushed out with a gun raised, "Is there an enemy?!" Yan Xuan said harshly: "I, I am testing the... Seismic resistance of your wall!" His ears turned red. From then on, he only dared to bathe in cold water (he had strong yin energy and was not afraid of the cold, but Su Muqing thought he was energy-saving and environmentally friendly).
