Modern student Xiao Yunxiu transmigrates into the body of a descendant of the previous dynasty, pursued by a Taoist priest. While fleeing, he stumbles into a forbidden area of the Regent's Palace and accidentally triggers a miraculous bone manifestation that draws hundreds of demons to worship him. Born with a spirit bone, he can summon hundreds of demons to worship him, but he has no idea. This makes him the target of Xie Wuhuan, the current regent. Xie Wuhuan appears gentle and refined, but is actually calculating and obsessively ruthless. He has spent ten years plotting to control the realm. After meeting Xiao Yunxiu, he falls for him in earnest and begins forcing his love upon him. Xiao Yunxiu is naive and oblivious, yet fate repeatedly thrusts him into the spotlight. Xie Wuhuan advances step by step, supporting him in public while imprisoning him in private, and secretly eliminating everyone who covets him. The two go from control and resistance to choosing each other, their slow-burning romance full of tension and push and pull. Later, fellow transmigrators will appear, the dragon energy will run wild, and other exciting events will unfold. In the end, the two will uncover the conspiracy behind the Great Yin Dynasty's thousand-year cycle of reincarnation.
