Yun Xiaoman, the "weakest" errand runner of the Guixu Sect, wakes up to find the sect in ruins and her senior brothers living in misery. Heartbroken, she resolves to provide for everyone—yet the porridge she cooks allows people to break through, the grass she pulls out gushes with spiritual springs, and the "broken stone" she casually slaps turns out to be a ten-thousand-year ginseng king. It turns out that a hundred years ago, she built the mountain-guard array with her chaos Dao foundation and has been sleeping ever since, while her three senior brothers guarded her for a full one hundred and three years, each covered in scars. As her memories recover and heavenly demons are about to break their seals, this girl who considers herself the "weakest" will once again fight to protect everyone.
