To avoid unnecessary trouble, Qin Sisi had Ye You put up an Invisible Bubble in a secluded corner.
Then, a person, a cat, and a ghost came to the door of Xiaolan's house.
Since Qin Sisi had previously helped Zhu Zihao deliver money to his family, she decided to use the same trick this time.
At the moment, Xiaolan's parents were quietly at home, one watching television, the other tidying up the room.
The sound of knocking echoed. It took the elderly couple a while to react, as it had been a long time since they had had visitors.
Xiaolan's mother put down her work, walked to the door and opened it, only to find an empty staircase.
Xiaolan, being a ghost, was invisible to ordinary people. Qin Sisi and Ye You, who was hiding in the Invisible Bubble, were also hidden from sight.
There was a black plastic bag on the ground, on top of which was a folded note.
