When Elian discovered this truth, he finally understood the reason for all his misery, and he snapped. His parents were dead, his fiancée was gone, and every hope for the future had been crushed, all while the bastards responsible for his suffering enjoyed wealth, power, fame, and beautiful women. With nothing left to lose, Elian launched a suicidal attack against a protagonist, and through an almost impossible stroke of luck, he accomplished the impossible feat of killing a Child of Destiny! Though it cost him his own life, death wasn't the end for him, and he unexpectedly transmigrated into a novel he had once read, becoming Ryan Longstaff, the kidnapped son of a multibillionaire family, destined to die miserably at the protagonist's hands. But Ryan refused to accept such a fate. 'Son of a bitch, you want to kill me and steal my girl? Then I'll f*ck your mother and sister on your grave! Let's see how you like that!' So what if this was a modern world filled with monsters, dungeons, and superpowered humans? If he could kill a protagonist once, he could certainly kill another, and this time, he even had the knowledge of the original plot and the help of the System. [Ding!] [Multiverse Villain System activated!] "Whoa... A Villain System?! Traveling across different worlds, destroying protagonists, stealing their heroines, and getting rewarded for it?! Awesome!" Now, it was his turn to take beauty, power, wealth, and everything from these protagonists. But would everything go the way he wants? Join Ryan on his epic journey as he builds his harem, plunders the protagonists' destinies, grows stronger, and struggles to survive in this new world while traveling to multiple worlds and completing missions, unraveling the truth behind everything. =================== Points To Remember: » The worlds he would travel to would not take up much space from the original world, and the story would still revolve around the main world. » In this novel, there will be 18+ scenes in some chapters, but nothing that would take away the fun of the story. » No NTR » All characters are 18+ » Criticism is welcome, but please be respectful.
