Being the Dad of the Villainous Kids in an Infinite Game

After transmigrating into a horror game, Jian Wan becomes a caregiver at Lita Orphanage. The System says, "Today is your first day working at Lita. The children may be a little mischievous. Your task is to work at this childcare home for three years. Once your term is up, you can receive a luxurious gift pack and return to reality." He pushes open the castle gates, steps into the garden, and sees the children sitting on the sofa in the hall. A dainty little girl with an angelic face. A sweet, well-behaved little boy with white hair and red eyes. A chubby little baby with a fluffy tail waves adorably and clings to him. "Daddy..." Jian Wan's heart is instantly won over. He hugs the child, moved. "What an adorable little one! This job is wonderful. Caregiver, right? Three years will be a piece of cake!" He goes to sleep without a care, but when he opens his eyes, he's back at the castle gates on his first day. The System says, "Your mission failed because you died. Welcome back to Lita Orphanage. Please work here for three years." Jian Wan: "?!" He pushes open the castle gates again and meets the adorable little ones all over again. That night, he trembles in fear and doesn't dare sleep. Before he can figure out what's going on, a shadow outside the door ends his life with a single slash. He opens his eyes, gripped by the terror of death, and despairingly pushes open the castle gates. Inside the castle, the adorable little one sitting on the sofa has demonic wings behind them. They tilt their head, revealing a sweet smile and sharp fangs. "Daddy, hug me." Trembling, Jian Wan: "..." He... doesn't dare move! This private childcare home has been shrouded in silence for years, filled with emotionless monsters of powerful demonic bloodlines. Then one day, a weak human caregiver pushes open its heavy gates. When the witch sings her song of death: Jian Wan: "No singing at night. Early to bed and early to rise keeps you healthy. Now, get under your blankets. It's time for a bedtime story about the Three Little Pigs!" The little witch: "..." When demons bare their fangs, everyone is afraid and runs away. Caregiver Jian Wan: "Come on, what's so tasty about this blood pack? Try the fries and meatballs Daddy made!" The little demon: "..." When the mastermind behind the breeding of powerful demons pushes open the castle gates, expecting to see a group of cold-blooded, merciless humanoid weapons, all they find in the courtyard is a line of children doing their morning exercises. Jian Wan enthusiastically shakes the mastermind's hand. "Hello, Duke. Under my care, the children now go to bed and get up early. They're optimistic, positive, and healthy. You can rest assured!" The Duke: "..." Theme: Stay positive and strive forward
