After a Century, My Dog Has Become a Demon

(Spiritual qi revival + the centennial deadline + Bureau 749 + decisive and ruthless protagonist)

Bureau 749: The centennial deadline hasn’t arrived yet. Your dog has turned into a demon, so we have to take it away and keep it under supervision.

Lu Yuan: Da Huang, you’ve turned into a demon? What on earth have you been eating!

Lu Yuan never imagined that one day Da Huang, the dog he’d raised since it was a puppy, would become a demon and be discovered by Bureau 749.

With no other choice, he took Da Huang and joined Bureau 749.
