Cao Zhen was able to reach the Golden Core Period Limit with the Nine Abnormal Phenomenon Golden Pill largely because of the Heretical Golden Core.
However, crafting a Heretical Golden Core requires not only a vast amount of resources but also an extraordinarily close connection to oneself. Thus, when he previously considered how to lower his cultivation base, how to circulate the Eight Nine Mysterious Art, and how to reach the physical Golden Core Period Limit, all he ever contemplated was self-destructing his Golden Cores—not destroying his Heretical Golden Core.
He felt that even if he were to self-detonate two, three, or even four Golden Cores, the impact still wouldn't compare to the devastating effects of detonating his Heretical Golden Core.
