Evil Born of the Heart speaks of demon nature.
The stronger the demon nature, the more one achieves with half the effort when practicing Devil Skill, greatly enhancing its power, and the demonic qi becomes purer and denser.
Therefore, if the Demon Emperor Six Paths were to obtain Moluo's demon nature, it would indeed greatly increase his power, cause the demonic qi to surge, and perhaps, if the two become one, he might have the ability to break through the Sky.
However, the stronger the cause and effect, the deeper the karma.
Obtaining profound demon nature will also rapidly amplify various desires, and if one cannot control the demon nature, it will backfire, leading to a drastic change in nature and loss of self-control, descending into frenzy, or worse, becoming possessed and devoured by demon nature, becoming a part of it.
