Eight years ago, Ma Tianci was abandoned by his family and lived in the Kunlun Mountains. On the verge of death, he unexpectedly received the inheritance of the ancient beast god and coexisted with the royal souls of a nest of Kunlun Tibetan Mastiffs. Eight years later, he returned to the city with his nine-headed Tibetan Mastiff brothers and became the king of the dark night.

Ma Tianci originally wanted to keep a low profile, but was forced to take action again and again.
