Lin Yun was always good at deceiving people. He would mix lies with the truth. And because his previous truths had won the Flower Fairy's trust, she naturally wouldn't suspect the subsequent lies—especially since she already trusted Lin Yun. She would have never imagined that Lin Yun would deceive her.
The purpose of Lin Yun's actions was merely to shift the Flower Fairy's hatred from himself to Hu Yuling and perhaps even to the entire Demon Race.
But that had nothing to do with Lin Yun. The Demon Race was the enemy, after all. It was simply a matter of setting a trap for them to fall into.
As for Hu Yuling...
When the time came for the Flower Fairy to want her dead, all he needed to do was quietly lend a helping hand. Wasn't a little maidservant supposed to relieve her master of his worries?
Upon learning the "truth" of the matter, the Flower Fairy was momentarily unable to accept it.
