Bai Yifan, a transmigrator, is reincarnated as an Iron-Clawed Chicken on Fengming Mountain and bound to the "Strongest Rooster System." Upon hatching, he slays a black python to level up; later, he consumes a Fengming Red-Gold Flower and battles a profound turtle, evolving his bloodline into that of a Crimson-Flame Iridescent Chick. When the snake-demon She Zhao massacres the flock, Bai Yifan destroys the enemy using his bloodline powers and obtains a Bone Spirit Flame seed, earning the reverence of the fox-spirit Tu Shanling, who hails him as the Demon King. He seizes the Water-Cloud Cave, devours the wolf-demon Lang Mie to form his core and take human form, and enters seclusion; during this time, cultivators from the Cloud Sect mistake him for the reincarnation of the Demon Emperor. Tu Shanling risks her life to protect him, and upon emerging, he overawes the crowd with his might, thereby becoming embroiled in the conflict between humans and demons.
