Although a Qiankun Grandmaster is known as "unbeatable among grandmasters,' throughout the Da Xuan era, Qiankun Grandmasters had also typically perfected their Martial Body before mastering the Qiankun Domain, only then reaching that stage, towering above the extraordinary grandmasters.
Yet, Chen Mu didn't need to.
His foundation and essence were simply too solid, too formidable. As long as he grasped the Qiankun Domain, he would be sufficient to ascend to that level, or perhaps push his Qiankun Martial Body a few steps further to Major Achievement, he might not be inferior to the past Qiankun Grandmasters.
About these, Chen Mu's heart didn't fluctuate much, for from the moment he embarked on the path of Qiankun, he was quite clear that he would inevitably become the strongest in the history of this path. Let alone the past Qiankun Grandmasters, even the Martial Emperor who founded Da Xuan, he didn't believe the opponent could match him in the same realm. That was impossible.
