In normal cases, if a demon were to see someone with a bloodline higher than them, then the first thought they would have would be killing the said person.
There are some conditions before that, however.
Those conditions are that the said person has authority that is ranked lower than theirs, and the one who awakened that bloodline is not so strong that they won't be able to defeat him/her.
Above all, the difference in their bloodline shouldn't be colossal.
The demon generals, or the higher-ups of the demon empire, wouldn't sit still after that.
Even if the perpetrator of the murder was a duke of the empire or a general, the others would not let it slide.
That was the case for Alex.
He had a bloodline so highly ranked that just the mere presence of that bloodline was enough to bring the demons to their knees.
Yes, there was no way they would turn loyal just because of the bloodline, but at least they wouldn't show it upfront.
