The Pretty Airhead Is Always Targeted by Sinister Villains [Quick Transmigration]

Shen Xijun is a peach blossom spirit. While undergoing a tribulation, he was struck by heavenly lightning and sent into a quick transmigration world. System: "Your mission is to kill the evil main villains in every world." Shen Xijun raised his soft, delicate little face, pointed at himself in confusion, and asked timidly, "...Me?" System: "...Never mind. Go play." Shen Xijun: ...? Because he was so weak, his mission changed from killing the main villain to gloriously sacrificing himself as a minor cannon-fodder character so the protagonist could kill the main villain. But Shen Xijun never expected that he would survive every supposedly fatal plot point, while the looks the protagonist and the villain gave him grew stranger and stranger. [Cthulhu World] He is cast as the only "messenger" able to connect three-dimensional and four-dimensional space, and sent as bait to lure an ancient evil god into a human trap. But the unfathomably powerful evil god wraps a cold tentacle around the top of his thigh, bites his ear, and whispers, "Humanity should be grateful they offered you to me, my consort. That spared them from destruction." Meanwhile, the general who offered him up as bait eventually kneels before the sealed space portal, abandoning faith and dignity to beg the evil god to release him, even at the cost of all humanity. [Xianxia World] He is cast as the righteous Immortal Venerable's junior disciple and sent to poison the evil Demon Lord's wine. But the Demon Lord calmly drinks the poisoned wine, then leisurely grabs him by the ankle and drags him back to bed. "Fool, what you just gave me wasn't poison. It was an aphrodisiac." Meanwhile, his aloof and untouchable master eventually fights his way into the demon realm, covered in blood, his eyes red. "Return my junior disciple to me." [Vampire World] He is cast as a holy son whose blood has a special fragrance, and sent to stab a silver dagger into the heart of the progenitor of vampires. But the thousand-year-old vampire rubs his sharp fangs against his delicate neck and says seductively, "Let me bite you and mark you. Then I'll spare the werewolf who sent you here." Meanwhile, the werewolf brother who raised him and expected him to give his life for the pack eventually cuts out his own heart, just to beg for his forgiveness. [ABO World] He is cast as an Omega born with alluring pheromones, and sent to seduce and assassinate the villainous Alpha. But the Alpha locks him inside a villa, strokes his belly, and murmurs darkly, "I'll let you out when you get pregnant." Meanwhile, the man who gave him the mission in the first place sneaks into the heavily guarded villa and caresses his slightly rounded belly. "Baby, get rid of it. Wouldn't you rather have my child?" [Supernatural World] He is cast as a young Taoist priest with yin-yang eyes, and sent to stick a yellow talisman on an evil ghost's forehead. But the ghost takes the talisman from him with ease and presses it to his own forehead. His cold palm strokes the back of Shen Xijun's neck as he says ominously, "You've been pretending you can't see me all this time, just for this?" Meanwhile, the head of the family who raised him for eighteen years solely to steal his special constitution eventually searches tirelessly for Taoist priests across the land, just to find the soul the evil ghost stole from him. Other worlds to be decided: [Apocalyptic Zombie King] [Miaojiang Black Wizard] Shen Xijun: ...Something seems wrong. Why are both the villains and the protagonists lusting after his body? [An innocent, silly, sweet, soft beauty bottom x all kinds of dark, obsessive, possessive, extremely yandere tops] Note: 1. The villain is the true top. The righteous protagonist is a scum top (he isn't one of the top's fragments). The scum top will suffer the consequences, but the bottom will only end up with the true top. 2. The villain will dote on his darling to an extreme degree. 3. The top's fragments are the villains in each world. Theme: When evil runs rampant, love saves the day
