The Blood Emperor is not the ancestor of the Blood Family, but the cultivation technique practiced by the Blood Family Ancestor Blood Emperor is somewhat related to him, considered to be passed down in one line.
The soul of the Blood Emperor was weak, passed through several hands, and eventually landed in the hands of Xue Wuhen's mother, then onto Xue Wuhen.
Upon discovering Xue Wuhen's strong Blood Emperor bloodline, the Blood Emperor expended soul power to help Xue Wuhen awaken the Blood Emperor bloodline and taught him the Blood Emperor Scripture.
The Blood Emperor Scripture had some manipulations; once Xue Wuhen cultivated to the Divine Skill Realm, he could easily possess Xue Wuhen, take over his body, resurrect, and reign supreme.
But he didn't expect Xue Wuhen to just die like that.
He cultivated him for twenty years, even expended soul power to awaken the Blood Emperor bloodline for Xue Wuhen, but because of one sword from Zhou Chen, all was for naught.
