😋I think this book," Familiar: Start with Summoning ", might fit your description. The protagonist, Qin Tian, has an origin system. He only needs to consume origin points to be able to kill the sky, the earth, and the air. Activate the Summoning Space, starting from the Summoned Beast. Little Skeleton + Origin Points = Skeleton Dominator, Iron Thread Worm + Origin Points = Mastermind, Grass + Origin Points = Head of a Billion Swords. As the summoned beasts level up, there will be more and more types. Perhaps my senior sister's summoned beast has obtained the ultimate evolution and become a powerful summoned beast that can affect the entire continent. In short, it's very exciting! I hope you like my recommendation.😗
