I Raised the Future Tyrant

Rong Ci was forcibly kidnapped by a System and transmigrated to an alien planet, with a script shoved into his hands. It was a web novel from a certain site. The protagonist, who was supposed to become an excellent emperor, strayed from his destined path, became a tyrant, and ended his life by suicide. With the protagonist dead, the story couldn't continue, and the world collapsed. The System that kidnapped him told him: If he couldn't save his target, he wouldn't be able to go home. System (excited): "See the protagonist getting beaten up over there? Hurry and save him, then get him to like you!" It even handed Rong Ci a script for a gentle, big-brother type. Rong Ci said he couldn't do it. Instead, he played the part of a madman from the start, stepping on the protagonist's hand and making up an identity to give himself more lines, all while laughing maniacally and spinning a tale. Then the System watched as he successfully conned the already corrupted protagonist into a complete mess. At last, the mission was complete, and Rong Ci faked his death to go home. That was what he thought the ending would be. But that dumb System came back and said, "This is bad! He found out you're not dead, and now he's coming here to attack!" Three days later, Rong Ci watched as the alien emperor, black-haired and golden-eyed, led his troops to blockade Earth and declared that he wanted to see him. System: "So what are you going to do?" Rong Ci raised an eyebrow. "Con him again?" * Is it hard to tame someone? Not really. A false peace is the basis of friendship. Give him a little honey to put him at ease. When he refuses to be tamed, deliver a whip-crack he will never forget. Even a fierce, unruly beast can be trained to kneel at your side and bow its head in submission. He'll obediently put a collar on himself and become your loyal dog. From then on, there'll be no need for shackles. Invisible chains will bind him forever. Samuel was the successful test subject in this plan. Even though Rong Ci was so cold and cunning, scheming against him and mercilessly trampling on his sincere feelings, Samuel still became so madly infatuated with him that he couldn't break free. Bonus Scene Imperial Negotiation Team: "We can negotiate everything else, but he has to be our empress." (They toss out a photo of Rong Ci.) Earth's Negotiation Team, who thought they were about to be colonized: "..." What the hell are you talking about??? Content Warnings: 1. The love interest is a little tsundere at first, then becomes a loyal dog. 2. The protagonist is a sadistic, refined scoundrel. 3. Happy ending. Theme: Relationships between people should be built on sincerity.
