Wei Wuyin wasn't willing to simply end the matter like this. He decisively shook his head and said, "I went through quite a bit of trouble to resolve your inheritor's issues. All of which, he had caused. All to obtain the ring, you, and I'm not someone to simply surrender without obtaining some gains in return." A tinge of arrogant stubbornness suffused his words.
It would truly be an unfortunate outcome if he were to simply return this protective amulet and supreme expert to the hands of someone who wanted to kill him. While he knew that likely all of his plans were dust before a desperate Wu Yu within his own sect, he didn't relent to his will.
Wei Wuyin wasn't a saint; he would never act to benefit another without first calculating his own reasonings, desires, and subsequent gains. While he could be selfish, acting on his own desires, this was a rare occurrence that typically occurred when he was emotionally invested into something or someone.
