I’m on a Rampage! I Have the Villainous Male Lead Eating Out of My Hand

Synopsis: The hard-working author launches a new book! A world of high martial arts! The ultimate laugh-out-loud power fantasy, packed with anti-clichés! I actually transmigrated into a novel as the villain’s lackey? The kind who doesn’t survive three chapters! What should I do? Help, I need answers! Huh? Why is the villain so nice to me? Money, a house, a car, pills, women... The villain’s experience points? I’ll take those! The protagonist’s luck? I’ll take that too! The heroine? I’ll take... I’m on a rampage! I’m playing both sides, taking from both, and milking every opportunity. The most shameless villain’s lackey in history!
