Although Master Qingwei had always known that Zhou Chun was cultivating the Secret of Dragon Transformation,
the Dragon Transformation Sect was, after all, long ago classified as a heretical sect. As a nominal disciple of Green Lotus Temple and its Sect Leader, wouldn't Zhou Chun be slapping his own master's face if he used the Dragon Transformation Secret Technique on the battlefield?
Moreover, his foundation in the Dragon Transformation Secret Technique had already been converted to the bloodline of the Thunder Flood Dragon Baibai. If he were to display it at this moment, it would be tantamount to informing those in the know that his Spirit Pet Baibai was not some Thunder Python, but a true Third-Order Thunder Jiao!
So even though he could have fought the Demon Cultivators of the Beast Demon Palace at close quarters after using the Dragon Transformation Secret Technique, he never entertained such an idea from start to finish.
