I Let You Control the Beast, but Not the Goddess.

On the day I awakened my D-class demon power, the school beauty threw a rose on my face - "You deserve it too." Oh, how could she know that this is the moment I have been waiting for. After two and a half years of dormancy, the system finally woke up. Ignoring the level-enforced contract, I took over the nine-tailed demon fox school belle and let me do whatever I wanted. After that, I pushed Qingluan all the way to avenge his friends? Receive! The True Ancestor of the Vampire comes to your door? Receive! On the Badi battlefield, the fifth-level Naga knelt down in front of me and begged for mercy; in the realm of beast control, the world ranking was trampled under my feet, and the eighth-level demon emperor begged me to do something.
