Xuan Chen, the cold immortal king, and Ye Heng, the prince of the Demon Realm who hides his identity, are a master and an apprentice, and their love grows secretly as they accompany each other day and night. Xuan Che colluded with the traitors in the Demon Realm and framed him with soul-eating cruelty, forcing Xuan Chen to draw his sword and destroy the disciple. He said "the relationship between master and disciple is broken", which hurt the young man and hurt himself even more. Ye Heng went down the mountain with hatred, returned to the Demon Realm to quell the rebellion, killed the traitors, and returned powerfully as the Demon Lord; Xuan Chen guarded Chen Xiao to resist the evil spirit and block the plot, just to wait for him to turn back. The two teamed up to break the soul-devouring formation, eliminate the Shura clan, survive the test of life and death, and finally break the barrier between immortals and demons.
Intention: etiquette is the form, good and evil are the expressions, the direction of the heart is the right path, and the love can determine the three lives.
