Review Detail of HighLander in Talent Swallowing System

I liked the book for a while but it got tiring when he is around his loved ones for a 100 chapters but doesn't bother telling them his real identity because he wants to meet them after "completing" his revenge. MC is warm to his loved ones and sits on a very high horse when it comes to the topic of slavery but doesn't really mind massacring an entire family ( a lot of whose members definitely never even heard of him ) in the name of cutting loose ends ( man is ruthless as hell. )
