In a world where magic and divine power collide, the youngest son of Lucifer, a demon boy born with unimaginable strength, was chained and sealed away by his father to prevent him from destroying Hell itself. At the age of eight, his power became so uncontrollable that even the King of Hell feared his existence. Desperate to keep the demon's destructive potential contained, Lucifer made a pact with the great Merlin, who trapped the boy in the human realm, binding his powers with enchanted chains.Years later, with Merlin dead and a kingdom still fearful of the demon’s release, an elite group of knights, blessed by the gods, take it upon themselves to guard his prison. However, when a war between the mages and knights erupts, chaos provides the perfect opportunity for the young demon to break free.Hidden among the knights, disguised within their ranks, the demon plots his next move.

As he travels deep into enemy territory, sneaking into the heart of the kingdom, he is driven by one purpose: freedom.Now, with his powers still sealed but his physical strength unmatched, the young demon embarks on a journey that will shake the foundation of both realms.

Wei Lan accidentally transformed into a cannon fodder girl of the era. She was dissatisfied when she went to the countryside for her brother and broke up with her family.

Because he was greedy for the male protagonist’s “beauty”, he was framed by another cannon fodder’s female partner, and successfully married a second-rate man in the brigade. In the end, he died in a foreign country. It can be said that he was a master of death!

Wei Lan, who is familiar with the plot, said who the male protagonist loves! Please let me be beautiful alone!

                                                                                                                                                                                                                                                        The female protagonist who wears books and is a squeamish woman VS the male protagonist who was ruthless in the early stage and didn’t talk much in the later stage.

(The heroine has a delicate setting, she doesn’t like to stray in, her daily purpose is: sweet, sweet, sweet!)

Note: There is another male protagonist, not the male protagonist in the original book.

They say this unhealthy atmosphere was brought about by you, as the new generation's Duel King. What do you think about this?” a reporter asked during an interview.“Slander! Pure slander!”Kira was angered by this accusation.“Why say it was me who started this?”“Dueling has always been like this!”It's not his fault.Who let him play Yu-Gi-OH!
