In the end, the butler let Shen Chun in.
Shen Chun asked the two of them to guard outside and not disturb her.
When she arrived at the Fu family's old residence, she realized that the malicious ghost was not here at all. Shen Chun saw that Old Master Fu did not have any sinister energy around him, but he had lost his soul, so he could not wake up and was trapped in a nightmare.
After Shen Chun opened the door, she said to Song Han and the butler, "Old Master Fu is having a nightmare. His soul is trapped inside. I'm going to cast a spell to enter Old Master's nightmare later. The two of you, guard him well. Even if Fu Shi comes over, tell him to wait outside obediently."
Seeing that Song Han and the butler understood what she said, Shen Chun closed the door again and fumbled for the Dream Soul Bell in her bag before hanging it on the window.
When a breeze blew, the Dream Soul Bell would echo in one's ears.
