Synopsis: The founder of the Wusheng Sword Sect, Tian Xiezi, has mediocre talent. To break through to a higher realm, he secretly cultivates by drawing on the primal yin of beautiful immortals. But in public, he remains a revered patriarch of the righteous path, a paragon of strength, kindness, and light, adored and admired by the sect's junior disciples. Meanwhile, the Sword Sect's senior disciple goes to any lengths to save his innocent little junior sister, who knows nothing of the world's dangers. To avoid arousing their founder's suspicions, he always acts like a wicked schemer. Yet behind the scenes, he has been protecting the Sword Sect's light and hope all along. So when everyone believes him to be a demon from the depths of hell, there are still some who insist he is the kindest angel from the highest heavens. And thus resentment and gratitude quietly unfold amid it all.
