Dahuang: in the Beginning, My Sister Becomes a Spirit and Comes to My Door Every Night.

"Li Tianran, you are mine, no one can separate us!" Listening to this voice, Li Tianran then felt that he was trapped in a cold, damp and narrow space, with only the murmurs echoing in his head. After his sister disappeared, Li Tianran had nightmares like this every night until his good friend Wang Mingguang showed up. He turned out to be an exorcist and told him that his sister was dead and had turned into a spirit to haunt him. The only way to be saved was to fulfill his sister's last wish before she died. Li Tianran is panicking now because his sister's last wish before she died seems to be to accompany her by himself. What should I do? I'm waiting online. It's very urgent.
