Duan Ling Tian had pondered upon it before deliberately asking Zi Yun's direct disciple to pass the message saying that he had avenged Zi Yun.
Although he had used another disguise and name to make his move in the Windfall Nation's Imperial Palace, due to the fact that Zi Yun was Feng Tian Wu's master, Duan Ling Tian did not intend to hide this from her.
As for this direct disciple who was asked to pass the message, when Duan Ling Tian had first met Tian Wu in the Drift Blaze Sect, he had learned from Tian Wu that her senior sister was an orphan who was taken in by her master when she was young. Thus, she treated her master like her mother and cared for her very much.
For this reason, Duan Ling Tian was not worried she would spread this news out. Naturally, even if she did, not many people would believe her.
