My messenger is a little fox

Introduction: Li Yu inexplicably traveled through his own work. He thought he would reach the peak of his life, but found that the original story trajectory had changed. This is a world where humans and angels coexist. If humans want to become stronger, they can only contract with the most powerful angels. I originally wanted to follow the path of the protagonist and start a life of passion and cheating, but I was tricked by fate and made a contract with the weakest familiar. Frustrated, Li Yu had to settle for the next best thing - getting rich would mean peace. Unexpectedly, fate played a joke on him again, forcing him to embark on the road of becoming stronger.
