Alright, well that music was really loud for no reason.

Damn. and so the plot thicken's thinking it was the holy lord all this time that killed his father, but in fact his very own brother, now ain't that something.

Yes, But maybe his brother was a possessed puppet, like many in this story, because he never returned to his family for their treasure, the black dragon and to use his family reputation.

There is another twist there. His brother was only ordered by his mother to kill his father. But in reality, they all didn't die. It is just to test the mc (it's difficult to remember his name) and make him stronger along the way.

Testing people still makes you an a**hole either way ,especially in that way
