Awakened in the modern world after millennia, Matthew Moore—once Emperor Quinn—finds himself appointed as Shadowguard Division Captain but receives little support. To break his cultivation limits, he seeks Melody the Muse, gathering three talented female disciples connected to her. Together, they embark on a thrilling journey.
Samuel Yerkes married Wendy Lake due to his family's decline and gave her his corneas. But he was thrown out of the Lake family after Wendy’s eyesight was restored, and the Lake and Zeus families even plotted to have him killed in a car accident. Luckily, Samuel formed ties with the perpetrator of the car accident, Sienna Yale (the most beautiful woman in River City), and the blood dipped into his mother's jade pendant awakened the Devil of Essence, who passed on profound magical powers to him. In return for Samuel’s curing the chronic disease of Mr. Yale (namely Sienna’s grandpa), Sienna promised to find out the truth about his parents' death three years ago. After that, Sienna expressed a liking for Samuel and got involved in his revenge against the Wells, Zeus and Lake families.
