Every legacy system has its own separate inheritance, with records of the experiences of predecessors that are all different.
Moreover, each inheritance system has produced a Nascent Soul Ancestor in the past or present, and it is for this reason that the sects are unable to overly interfere with such matters.
In addition, the most crucial point is that the 'Earth Evil Demon Skill' has very high cultivation requirements; even within the Earth Evil Sect, there are not many cultivators who have the ability to practice it. The 'Earth Evil Demon Skill' is only passed down among elite disciples, so the sect does not worry about the technique being leaked.
Like this Mid-stage Golden Core Cultivator, the reason he possesses the inheritance of the 'Earth Evil Demon Skill' is that he is the strongest practitioner in their inheritance system; thus, the legacy of the 'Earth Evil Demon Skill' is preserved in his hands.
