Zhao Hao, a modern office worker, transmigrates into a world of immortal cultivation and becomes expendable cultivation material for the Corpse Refining Ceremony of the demonic sect Extreme Yin Sect. He possesses the universally despised five-element mixed spiritual roots, considered utterly useless. At the brink of death, he awakens the Myriad Things Enhancement System and sacrifices four spiritual roots to strengthen his fire spiritual root. By a twist of fate, the sect mistakes him for the rare fire-element Heavenly Spiritual Root. Maintaining his false identity, he carefully navigates the demonic sect while secretly enhancing his cultivation techniques and power. After slaying his pursuers, he escapes to the neutral immortal city of Myriad Immortals City. Using his system's abilities, he makes a name for himself at a grand alchemy gathering and becomes embroiled in a struggle over the legacy of the ancient Lihuo Sect. Amid countless dangers and opportunities, he rises against the odds.
