Quick Transmigration: The Host Is the Real Villain

[1v1, Female Pursuer, Sweet Romance, Tsundere, Scheming, Yandere Male Lead x Coolheaded, Rational Villainess] After being imprisoned for three hundred years, Yin Li binds to a System and transmigrates into different small worlds. He works hard to complete his missions so he can win his freedom, never expecting to run into his nemesis! He meant to get revenge on her, but when he saw her injured and being bullied, he couldn't bring himself to do it. Assassin Qi Yue: “Help me, or die!” CEO Yin Li: “Heh, woman, you've successfully caught my...” Before he could finish, a loaded gun was pressed against his abdomen. “No! I'm saving my first kiss for my partner!” Bodyguard Qi Yue: “Master, you belong to me.” Yin Li: There's an offer like that? The crazier you are, the more I love you. Vampire Queen: “You're my prey. Don't even think about escaping.” Imprisoned Yin Li: “Don't think you can win my heart by doing this!” Let the storm rage even harder! I'm not afraid of you being crazy, I'm afraid you won't be. Immortal Venerable Yin Li: “Demoness, put down your weapons and repent.” Demon Lord Qi Yue: “Get lost.” “How dare you tell me to get lost?” [Ding! Warning! Warning! Host's corruption level has exceeded 80!] Qi Yue: ...So which one of us is the villain? P.S. The male lead, Yin Li, travels through worlds to win over the female lead, Qi Yue. They fall for each other mutually. Minor spoilers: The leads' crazy, yandere traits emerge in the third world. There won't be any sudden corruption; everything follows a cause-and-effect logic. Those who walk alone will always meet interesting people.
