As a descendant of the "Blood Drinker" Haibo, still a Demon Hunter, the ancestral mansion of Viscount Windsor preserved a significant amount of records related to this "Blood Drinker."
It was precisely because of these records that he was able to find some secret techniques of the "Blood Drinker" Haibo during his time as a Demon Hunter in the Windsor Family cemetery.
Particularly among them were records of the period when Haibo was on the verge of becoming a "Blood Drinker."
Viscount Windsor was certain that those notes were written by Haibo himself.
As for why Haibo left these notes within the Windsor Family?
Viscount Windsor didn't know.
However, the Viscount was clear that if he wanted to live a stable life with Ross, he would certainly need tremendous strength.
So, he moved into the cemetery with Ross.
There, he unearthed one of the graves, meticulously researching those secret techniques.
As for the guilt toward his wife?
It was also real.
She was a good woman.
