This spirits are really intelligent, because they have wide experiences for living for so long. The young master is really brave and strategic. I really like the dialogue and how they exchanging this powerful words and showcasing their philosophies. His heart is the strongest. This ep is a hard episode, because it shows how far can some go with wrong intent, blinded by greed and selfishness, but it’s sad that an entity can go that far just how badly they wanted something and neglecting everything.
