背景通天，舔什么狗？！

[Villain + decisive killing + system + background invincibility + domineering] Xiao Ce traveled through time and became the legitimate son of a top family. The ancestor is a quasi-emperor! My father is the pinnacle of the Great Sage! He can be called the prince of the fantasy world. I thought Long Aotian had the script in hand! But it turns out that the original owner is the ultimate bitch, and is being used as a human-shaped self-propelled cash machine by Green Tea's fiancée. While receiving the magical elixir he gave her, she sighed to outsiders: "It's hard to refuse such kindness, but it's actually not what I want..." Xiao Ce drew his sword with his backhand, preparing to physically transcend this green tea. At this moment, a cold mechanical voice sounded in his mind: [It has been detected that the host has deviated from the character design, and the villain system is officially activated! Xiao Ce smiled. "The system made me the villain? What a coincidence, I'm a professional counterpart." "Go to hell with the Son of Destiny, go to hell with the savior." I have a supreme background! There is also a villain system! Why do I still have to accept your insults? From today on, I am the biggest villain in this fantasy world! Fiancée? Kneel down and kowtow. Destined child? Trampled underfoot. If this Heavenly Dao dares to be partial, I will destroy this Heavenly Dao too!
