Lu Chengfeng's current cultivation is vastly different from before, and his refinement of the Void Dragon-Binding Rope has gone deeper, "With my current cultivation, I should be able to obtain another Taoist skill, the Void Capturing True Technique, from the Void Dragon-Binding Rope."
"To truly bring out the greater power of the Void Dragon-Binding Rope, I need to advance the Great Five Elements Extinction Divine Light Sword and the Void Capturing True Technique in parallel, and possibly even cultivate the ultimate divine technique."
"Although the Void Dragon-Binding Rope is immensely powerful, it still isn't the Five-Colored Divine Light. Since the ancestor left so much legacy, there is a good chance they also left the Five-Colored Divine Light as a divine technique."
"I suspect the Five-Colored Divine Light's legacy is hidden within this Hidden Dragon Cave Heaven, but my current cultivation is insufficient to find it just yet."
