After one night, although the group's experience was amazing, they still did not see the ghost, so they made an appointment to explore again. After learning that Xia Lidong participated in the haunted building operation, Xia Lidong's lover, Liang Haonan (played by Chen Sihan), a married man, unexpectedly expressed his support and sent Xia Lidong to the haunted building.
