Tuo Bihan soon went through the list, delivering the rings to their destined recipients. He no longer felt that his decision was incorrect, and from the previous reactions of Su Mei and Na Xinyi, it seemed he had made the perfect decision.

Perhaps the rings couldn't even be seen through without a special means, hence the spiritual seals.
The more Tuo Bihan considered these things, the more astonished he was of Wei Wuyin's means and foresight. Almost always, he found out that the more he learned about Wei Wuyin, the more incredible things were revealed. What other secrets did the little boss hold?
