Huo Fenghuang was not playing around. She used her Heavenly Eye Technique to see through falseness. Unfortunately, Ao Shen used an Extreme-level Innate Treasure and could use a lot of its power with his Immortal Venerable strength, so she could not detect him.
So, Huo Fenghuang used the background of her Ancient Clan. Although Qiyuan almost left them broke, after so many years, they recuperated to some degree.
She waved her hand to summon an Extreme-level Innate Treasure in the shape of an eye–its name was Phoenix Eye.
'Find you,' thought Huo Fenghuang before instantly appearing before Ao Shen, using a brilliant application of Yin-Yang Dao. The distance between her and Ao Shen was considered "far" or "long," but using Yin-Yang Reversal, she made it "near" or "short," thus achieving instant teleportation.
