The Beloved Little One of the Villain Squad

This is a fictional world where the protagonist is always invincible. The villains, numbered One through Five, have been beaten to a pulp again and again, and they're sick of losing. The System tells the villain team that Zong Sheng can lead them to defeat the protagonist. He's the key to turning the tables. The villain team immediately decides to find Zong Sheng and finally get their revenge. But when they arrive, they discover that Zong Sheng isn't some hidden powerhouse with overwhelming strength. He's... A freshly turned five-year-old toddler with boundless energy. Villain team: ...Forget it. We can raise him. There's still hope. The villain team adopts Zong Sheng, planning to raise him into a highly intelligent criminal. The result: Villain One, naturally cold and born evil: “You'd rather herd cows than go to school?” (expression crumbles) Villain Two, picky and severely germophobic: “You stepped in dog poop?! Don't come near me!” (leaps away) Villain Three, always composed and a genius: “Say that again. What's four plus eight? Forty-eight?!” (collapses, spitting blood) Villain Four, short-tempered and petty: “I've been reading you bedtime stories for an hour. Can you go to sleep already? What, you want to hear about a domineering CEO who runs away with his baby?!” (frantically tries to revive himself) Villain Five, sick of life and practically dead on his feet: “They called your parents to school again? Why am I still alive?” (closes his eyes on the spot) The villa is in chaos every day. The villain team gets so angry they really want to assassinate Zong Sheng, but... Whenever they're hurt, it's Zong Sheng who puts medicine on their wounds and blows on them. When they're sad, it's Zong Sheng who cheers them up. And Zong Sheng remembers every one of their birthdays. As time goes by, the villain team starts to dread the protagonist's arrival. They're afraid the protagonist will hurt Zong Sheng, and afraid they won't be able to protect him. * Zong Sheng loves his family, even if they're ill-tempered, hard to please, snobbish, and full of themselves... But she will protect them. One day, when the villain team goes to pick Zong Sheng up, they unexpectedly find him face-to-face with the protagonist. Everyone's heart leaps into their throats. The next moment, Zong Sheng deftly throws the protagonist over his shoulder, then plants his hands on his hips and laughs loudly. Villain team: (gasps) (uneasy and suspicious) (seems fine) (cheers loudly) (embraces one another in tears) Thank goodness, Shengsheng isn't afraid of the protagonist! There's hope for this family! *A story about a group of dysfunctional villains stumbling their way through raising a kid.
