The adventure of an ordinary herbalist's son.
In a peaceful era of Joseon where war is absent and the nation is stable. In a village where forests and rivers flow, strange rumors began to circulate. They say strange shadows appear at night, and people go missing. Naturally, people dismissed these rumors as mere hearsay. However, as coincidences continued to pile up, people began locking their doors one by one after dark. Yoon Sahyuk, the son of a herbalist, went into the mountains on an errand for his father to find the legendary herb known as Wolryeongcho, a panacea for all ills. There, he encountered a Sim-gwi monster named Cheongseol. Saved by a man named Kim Dokyeom, a 'Wol', he eventually joined the Wolsadae. Time passed, and after meeting his companions Seo Yuchan and Han Jinhyuk, the day of their first mission at the Wolsadae continued.
