Wang Zheng transmigrates into the world of immortal cultivation and unexpectedly becomes a disciple of the Ten Thousand Demons Sect. With a double-sided bronze mirror capable of copying treasures, he rapidly advances his cultivation. After killing Zhong Yingqi, a disciple of Purple Qi Mountain, he seizes numerous magical artifacts and spiritual consciousness techniques. Seeking spiritual herbs to cultivate secret arts, he trades a jade slip capable of breaking formations for medicinal herbs and powerful Bai Miao Pills, greatly improving his cultivation and spiritual sense. Later, the sect undergoes reforms and begins assigning mandatory missions. Wang Zheng joins a team sent to guard a spirit stone mine, where he unexpectedly discovers disciples of Purple Qi Mountain and encounters Huang Qing, a former fellow disciple who once betrayed and fled the sect.
