Lu Mingfei, how can you slay a dragon if you don't play the villain?

After seventeen years of living a life of idleness and complacency, Lu Mingfei was ultimately driven by a momentary desire and bound himself to a villain-cultivation system.
However, the task issued by the system left him dumbfounded.
Rebel against your aunt? Get first place in your grade at the end of the semester? Reach the limits of human physical endurance within 100 days? Failure to complete the mission will send you to heaven?
Lu Mingfei felt that either the system had gone mad, or he had gone mad!
In order to avoid going to heaven, Lu Mingfei had no choice but to muster his courage and try to complete the tasks issued by the system.
As a result, the system tasks became increasingly absurd. Lu Mingfei looked at the task display on the system panel:
[Daily Task: Please bathe in Chu Zihang's Flame for one hour!]
Side Quest: Elope with the little monster and become an enemy of the world!
Main Quest: Collect the Dragon King's Authority! Rebel against the world!
Lu Mingfei was on the verge of tears: "Six hundred and sixty-six, I'm not even going to act anymore!"
System: "Crying! Crying also counts towards your time limit!"
