Hence, the people that wanted to snatch the art of managing ghosts returned empty-handed and disappointed.
However, some people tried to find other ways to obtain the techniques.
During that time, many people from the Qian family were killed and injured. This huge family was destroyed within a short period of time. The people left in the Qian family started concealing their identity.
The power of the Qian family was dependant on the number of ghosts they helped to cross over. The more ghosts they helped, the more powerful they became.
As time went by, there were fewer and fewer people in the Qian family.
Around 300 years ago, a bunch of people created something similar to the art of managing ghosts.
However, the last stage was changed from releasing ghosts to cultivating ghosts.
Without the blood of the Qian family, no one could help a ghost cross over.
This was also the reason why no one could be as strong as the Qian family.
