Transmigrating teenager Ye Chen unexpectedly activates the Number One Sect in the Heavens system, unlocking Immortal Emperor cultivation right at the start. He chooses Duanlong Mountain as the site to establish the Kunlun Holy Land, and subdues the Nether Bone Dragon—covered in gold and red with white bone armor—to guard the mountain gate. He successively takes in six Emperor- and Immortal-level prodigies as direct disciples, including Mu Yan of the Flame Spirit Body, Gu Yingluo of the Supreme Immortal Body, and Su Jian of the Supreme Sword Bone. He descends the mountain multiple times to sweep through hostile sects such as the Jinyu Sect and Qingxu, casually suppressing the ancestors of major holy lands. A fantasy immortal cultivation story about building the number one sect in the heavens.
