Li Nanfeng couldn't help but feel a bit uncertain.
However, the Sect Leader spoke calmly, "Don't be nervous. What does it matter if the cultivation technique is imbued with evil energy? I see that this technique is in fact very powerful. Remember, as long as it's useful, it does not matter whether it's a skill from the Demon Clan or a secret technique from the Demon Clan, just use it. Don't be like those pretentious righteous people who fear this and that. But still, in the Cultivation World, pretentious righteous people are indeed the majority, hence I will teach you a method to conceal your aura. Once you learn this method, using this cultivation technique will make it indistinguishable from other cultivation techniques."
A gleam of joy flashed through Li Nanfeng's eyes.
He hadn't expected this.
His Master not only did not mind but also wanted to teach him how to conceal the evil aura of this cultivation technique.
