After Wu Gang returned to the auction house, Yang Feng looked at him in surprise and asked, "What have you been up to? Why are your clothes dirty, and why did it take you so long?"
"Obviously, I had important things to handle."
Wu Gang smiled and asked, "How much longer until the auction ends?"
"This is the last item up for auction."
Yang Feng said, "Don't you want to take a look? It's a treasure; maybe you could use it."
"What is it?"
Wu Gang looked at the big screen and saw a tattered book. He frowned and said, "Could this be a cultivation technique?"
"Yes."
Yang Feng nodded and said, "Xu Bingke just mentioned that this item is a set of techniques from the Tianshan Sect called Feitian Step."
"It's from the Tianshan Sect?"
Wu Gang immediately became interested, but still, he asked doubtfully, "If this is a technique passed down from the Tianshan Sect, why aren't many people bidding for it?"
