Hearing Ren Pingsheng agree to join the Underworld, Wang Yu still found it somewhat unbelievable. Su Xin had actually pulled it off.
A Yang Spirit Realm expert stood at the very pinnacle of the Jianghu. Moreover, Ren Pingsheng was among the finest even within the Yang Spirit Realm, not on the same level as people like Cen Weizhuang of the Qingcheng Sword Sect or the Su Family Ancestor.
Wang Yu instinctively glanced at Zuo Wujiang. In truth, Zuo Wujiang would also have been quite suitable for joining the Underworld. Unfortunately, his luck was poor. He and the Heroes Association had formed an irreconcilable blood feud; one of him and Ren Pingsheng had to die. Thus, the one who died this time could only be him.
Though Zuo Wujiang and Ren Pingsheng had previously fought each other to mutual ruin, and Zuo Wujiang had nearly caught Ren Pingsheng with that gu insect in the end, that was only because Ren Pingsheng had no techniques for defending against primordial spirit attacks, allowing Zuo Wujiang's sneak attack to succeed.
In terms of overall strength, Ren Pingsheng was undoubtedly superior to Zuo Wujiang. Once he entered the Underworld and learned its cultivation methods, he would be able to make up for this sole weakness.
The ancient cultivation methods of the Underworld might lack other merits, but they possessed one distinct advantage: comprehensiveness—utter comprehensiveness.
Take Su Xin's True Explanation of the Ice Hell, for instance. Beyond its primary cultivation method, it included no small number of miscellaneous martial techniques and methods of application.
The Heroes Association's cultivation methods were far too mediocre, while the Underworld's methods certainly contained ways to defend against primordial spirit attacks.
They were not specialized primordial spirit cultivation methods like those of the Phantom Demon Path or the White Lotus Sect,
