The innocent and naive Lu Huanqu was coaxed down the mountain by her master and master's husband under the pretext that a demon lord had emerged, entering the Sword Peak of the Tianyan Sect to become the group favorite little junior sister. She seems ordinary, but she actually possesses peerless strength, accompanied by a transformed Vermilion Bird named Little Hot Pot. Along the way, she slaps the faces of doubters, works side by side with her senior brothers and senior sisters to complete dangerous missions, gets acquainted with aristocratic scions like Situ Lang, and cultivates joyfully while secretly investigating the traces of the so-called world-destroying demon lord.
