Quick Transmigration: Are You Going to Lock Me in the Black Room?

[Dual male leads + quick transmigration + semi-coercive + both pure + 1v1] This novel is complete. The gong is a little obsessive, but not too obsessive (whispers). Run if that's not your thing! For the sake of completing his missions, Ran Qiyue endured hardship and quietly bided his time at the villains' sides (not really), hoping they would turn over a new leaf. As long as they behaved themselves and obeyed the law, they could do whatever they wanted! The major villain in each world: “Anything?” Ran Qiyue, who somehow wound up on the villains' ship: “...I think that might be going a little too far.” World One (complete): Murderous regent gong x disposable little emperor placed under house arrest from the start (ancient court) “Your Majesty, as long as you behave, I'll give you anything.” World Two (complete): Imperial general gong x undercover agent on an enemy planet (sci-fi) “Your skills are mediocre, but you taste all right.” “An undercover agent? Perfect. I'm no good person either.” World Three: Cold, bloodthirsty thousand-year-old ghost gong x greedy little Taoist priest (supernatural) World Four: Powerful leader of an ability-user base gong x weak, helpless zombie emperor (post-apocalypse) Note: For the sake of later plot developments, the gong isn't a villain in every world, and not every world has a local protagonist. The gong is a little obsessive and far from perfect. In some worlds, things get too intense and I'll write a bad ending (if things go too far, he won't get a wife). He'll gradually improve as the missions progress.
