"Taiyi Immortal and Demon Chronicles: Earthly Fiends and Myriad Phenomena" is a xianxia story set against the backdrop of the Ming Dynasty, narrating the millennia-long conflict between the righteous and demonic paths. As the decisive battles between the two factions have occurred twice consecutively at Mount Kunlun, it is also known as the Kunlun War. Legend has it that during both the first and second Kunlun Wars, the righteous path, with the aid of the South Pole Emperor and the Ziwei Empress, defeated the demonic path, bringing peace to the Middle Yuan Realm. Our protagonists—the young emperor Zhu Yunwen and the righteous disciple Leng Shuangning—are the reincarnations of the South Pole Emperor and the Ziwei Empress. This time, internal turmoil arises within the righteous path, while the demonic faction plans to seize the opportunity to strike. The third Kunlun War looms imminent, and the course of this great conflict grows increasingly shrouded in uncertainty due to the intervention of a mysterious force, plunging the Middle Yuan Realm into crisis.
