Xiao Chen transmigrated into a cultivation world, originally just a lowly firewood-shed chore boy in the Hundred Flowers Immortal Sect with no spiritual root at all. While being bullied by a vicious supervisor, he accidentally activates the [Myriad Realms Dual Cultivation Check-In System], gaining the top-tier divine physique [Supreme Chaos Body] and the heaven-grade technique [Nine Revolutions Dual Cultivation Art]. From then on, Xiao Chen checks in to obtain top-tier techniques and divine weapons along the way, subduing and conquering the aloof sect master Ji Liuli, the tsundere sword immortal senior sister Ye Qingxue, and the fox-clan succubus Mei'er. He slaps the face of the Blood Demon Sect's young master, annihilates the demonic army with a single sword strike, rises to become the sect's number one supreme elder, and ultimately cleaves open the heavens with one sword, setting off on a journey to conquer all realms!
