The Villain Also Wants to Be the Protagonist

My name is Wang Fugui. I was born in the Wang Clan, one of the three major clans in the upper world. I am a young master. I have been gifted since I was a child. When I was 5 years old, I broke through the foundation building. I reached the peak of Dan formation at the age of 10. My family all thought that I had the appearance of an immortal emperor. I also thought that I would be like the protagonist and have smooth sailing and then become the king. Until one day, Ding, congratulations to the host for activating the villain system! Has the protagonist's plug-in arrived? Sure enough, wait, what is the villain system? The system said that it is to help the protagonist grow and then give experience, or to be the protagonist's younger brother, but the protagonist's name is Tang San. What? Tang San? ? This isn't Douluo Continent? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
