Quick Transmigration: Every Villain I Saved Turned Dark

After Song Yu had the misfortune of being hit by something falling from a great height, he unexpectedly became bound to a System. The System said that if he could successfully reform ten villains, he would be reborn and receive a ten-billion-yuan reward. Could there really be a deal this good? Song Yu immediately set off on a mission to bring warmth to the villains. But when he told them he wanted to leave, all the powerful villains he had saved turned dark... The sinister research tycoon: “Xiao Yu, I developed a drug. Take it, and you'll never be able to resist my advances.” The obsessive, hugely popular film emperor: “Xiao Yu, do you like the golden house I built?” The wicked Demon Venerable villain: “Xiao Yu, this ankle chain suits you perfectly...” Song Yu was on the verge of tears. He had no choice but to rely on the System to escape. To make matters worse, his rewards from the System had somehow become “Level Ten Beauty,” “A Sweet Voice and Soft Body,” and “A Slim Waist and Long, Straight Legs”! He's a grown man, so why give him all this ridiculous stuff? He's had enough. He wants to go home! One-on-one, both physically and emotionally.
