Han Xiaohan traveled through time and not only had a ghost exorcism system, but also a fierce ghost husband.
When I just crossed over
Han Xiaohan: Oh my God! Why does this handsome man keep following me?
Wen Ruyu: I am your husband, and it is my responsibility to protect you.
Han Xiaohan: Tsk, I have a ghost exorcism system and I don't need your protection.

Han Xiaohan: There are so many ghosts, so scary! Husband, come out and save me!
Intention: True love is invincible. Even though you and I are on different paths, I still love you
