2. Introduction to the story of the fourth season of Lucifer: Lucifer is a TV series adapted from DCVertigo cartoons of the same name created by NeilGaiman, SamKeith and MikeDringenberg, and tells the first stories of fallen angels. Tired of the Lord of Hell, Lucifer Morningstar (Tom Ellis, Merlin) decided to give up the throne, retire to Los Angeles and open an upscale nightclub called Lux. While the handsome and charming Lucifer was enjoying his comfortable retirement life-wine, beauty and music, a beautiful young pop singer was killed outside Lux. For the first time in ten billion years, he felt a strange feeling inside. Is it pity? Is it sympathy? This feeling deeply troubled him and made his best friend Leslie-Ann Brad (librarian) deeply uneasy. This single murder case also attracted the attention of LAPD homicide detective Chloe Dancer. She was noncommittal about Lucifer, but she was attracted by his ability to lure others into telling secrets and his desire to seek justice, punish evil and eliminate rape. They began to cooperate to trace the singer's real cause of death, and Chloe's kindness deeply shocked Lucifer. Lucifer, accustomed to the darkest side of human nature, was attracted by Chloe's purity and began to doubt whether his soul could be redeemed. At the same time, the angel D.B. woodside, the angel of God, was sent to L.A. to persuade Lucifer to return to hell ... Will this demon incarnate evil and do good, or will he eventually be pulled back to evil by nature?
