A Jade Pendant Opens the Life of a Monster

He was in a low mood at the time and did not pay attention to the jade pendant... "Ding, the system is activated, please complete the host binding as required." This is the plot in the novel, why did it happen to me? Mischief? I checked and found nothing. It's true. I'm going to be the protagonist. The protagonists in novels are all awesome. Okay, done... As each mission was released, he gradually realized that his evil life had just begun... This novel and its characters are purely fictitious.
