As the current marshal learned the truth behind his father's forced abdication, Long Tian felt his father's anger wasn't unjust. It is just that, it is hard to say who is truly the wrong one as both sides only had chosen the best course to save their loved one. It is just that because of this choice, the truth which was built up for years was wasted just like that. They are no different from enemies.
That night to learn the specific details of what happened in the past Long Tian sent his people to investigate. After all, information was gathered, the current marshal felt a bit overwhelmed. It is no wonder after his father had abdicated that things between him and his friend were suddenly gone for good.
The uncles who would visit the house even without invitations were now blocked at the gates and even the letters they sent were thrown to the fireplace by the old marshal without reading. It was only now that he understood how much that betrayal had harmed his father's heart.
