Han Zhao reached out and opened the scroll. On it was a ferocious Inky Flood Dragon.
"This is the fundamental diagram of the Furious Flood Dragon True Technique. Only the successors of past gang leaders and gang leaders can check it. I don't have any children, and my personal disciple is the next gang leader, so I'll teach you this first basic diagram first.
"This Furious Flood Dragon True Technique is the foundation of my Shangguan family's safety. It's also a top-notch divine technique that leads to the Seven Fiend Martial Saint Realm. You have to promise me that you won't spread it to outsiders before I can tell you the incantation for the First Level."
Shangguan Yunfei continued.
"Yes, Master. I'll remember it," Han Zhao said seriously. It was not a burden to call him Master. It was fine as long as there were benefits. Shangguan Yunfei probably had ill intentions by teaching him the family's divine technique so easily.
