Not long afterward, everyone in the Liu family was supposedly slaughtered!
In reality, it was not there had been no survivors from the Liu family, as there were still quite a few members who had survived. However, it was mentioned in the information that these people had all been captured and were cruelly experimented on.
To reproduce the blood of the sacred ones, many forces had secretly participated in the bloodbath.
In an attempt to give birth to children who've inherited the blood of the sacred ones, some members of the Liu family were captured and used for breeding. Others were captured and experimented on, to try and find out the specific characteristics of the blood of the sacred ones.
Those from the Liu family who weren't home were in various situations, but none of them were any better than those who died. Although these people from the Liu family did not die that night, they had suffered all kinds of persecutions afterward.
