After I defeated the Demon King, I was executed for false accusations by the heroines.When I came back to life, this was the first thing they said.“I know it’s shameless, but would you help us one more time? Without you, the world will be destroyed.”…Would you help them if you were in my shoes?

The cousin that Jing Huan has been closest to since he was a child was labelled as “the other woman” in a certain popular online game: only after devoting herself did she know that the other party was a jerk with a girlfriend.

After several days of being bullied online by people in the game, his cousin went abroad in a fit of anger and sorrow.

Jing Huan couldn’t take this lying down; he decided to take revenge for his cousin using the same method as that guy – buy a character in game and kill that slag guy thousands of times online.

With his strength and skill as the Great God when the game was first launched, wouldn’t he be able to kill that guy and force him to quit the server in minutes?!

He went online, eager to fight, but made a discovery after conducting a round of investigations — this slag guy was the number one DPS server-wide, number one on the expert ranking list, number one on the wealth ranking list, number one on the popularity ranking list, and number one on the fame ranking list.

Conclusion: Can’t screw him over.

Jing Huan felt despondent. He was just about to give up when he personally witnessed his dormmate’s online relationship end right after meeting each other in real life. The other party had sent fake photos and changed their voice, and had even cheated him of his money, triggering his dormmate so much that he was almost admitted to a hospital.

Jing Huan felt enlightened as a sudden realisation dawned on him. After comforting his roommate, he moved the high-priced voice changer back to his rented house overnight.
