Is it time travel? Is it crossing robbery? Or was Gongdou in the sky kicked down from the heaven by some fairy concubine? who knows?

However, Lian Youyou, a hot-mouthed girl, was stuck to her, her dead skin and rotten face was so sticky.
The white-haired wolf demon on the mountain, the noble son who turned into a butterfly disappeared, and the palace ladies who disappeared mysteriously…
A series of supernatural cases may seem like monsters acting as monsters, but they are actually humans acting as monsters.
The difficult and miscellaneous cases are definitely caused by people, and they are caused by demons and ghosts.
Is it someone playing tricks? Or a ghost? Is it a monster? Or be a monster? who cares?
Just as long as the people who eat melons express excitement!
After checking, why did Lin Tingjun and the other eight gods have their own goals and stories? Then who is she, Lian Youyou?
The ancient dimensional monsters are ready to move again, eyeing the earth!
Divine matters, demonic matters, monster matters, and human affairs are not as important as Lian Youyou’s protecting the earth!
