Goddess Development System

He becomes Yang Tian, an eight-year-old boy. When his older sisters help him complete tasks, they receive System rewards!

Eldest sister Lin Yatong: "I cooked him a loving late-night snack, and I noticed I got prettier."

Second sister Liu Ruoyan: "That's nothing. I helped him fulfill a wish, and this morning I won a hundred million in the lottery!"

Third sister Jiang Yurong: "What's there to brag about? I discovered that I can beat even god-tier assassins in combat!"

Yang Tian: "With the System's help, I've already made nine goddesses mine!"
