章節 664: Chapter 664: Overestimating Oneself

"Is this kid a demon?"

Heavenly River looked at Feng Wuchen with a face full of shock, unable to believe that after just a little more than a month, Feng Wuchen had actually made a breakthrough.

In this period of time, while Heavenly River was secretly surveilling and cultivating, his own cultivation had only improved by a smidgen.

In comparison, his cultivation speed was not even one thousandth of Feng Wuchen's.

"Buzz buzz!"

The Ninth Level Qiankun Divine Killing Array activated, the Dragon God Palace buzzed and trembled, and a vast expanse of golden light enveloped the Dragon God Palace.

"Feel free to try the Dragon God Palace's Ninth Level Qiankun Divine Killing Array!" Feng Wuchen said with a confident smile.

"To be able to set up such an intricate array at such a young age shows that your proficiency in formations is extremely brilliant," the stooped old man praised as he glanced at the formation, his astonishment evident.
