Naturally, Zhang Heng would not fully believe what the old man in the Tang suit said. However, the timing of the book appearing was indeed a big problem, but he decided to put this matter aside for the time being. Recently, he spent most of his energy learning to control the pair of newly acquired Shadow Wings.

After two weeks of training and exploration, he had finally mastered his flying technique, no longer landing face first.
