Impersonating the Female Demon Lord's Husband to Toy with the Original Story's Heroes and Villains

[Neutral NPC + Multiple Heroines + Conceptual Deity + Comedy + Toying with the Original Story's Heroes and Villains + Satisfying from the First Ten Chapters, and Gets Better from There]

Chen Xian transmigrated into a book, only to become a neutral creature in an urban cultivation novel. Everyone around him was an overpowered protagonist cobbled together from different books:

There was a miraculous doctor who had come down from the mountains, a Dragon King of Asura, a reborn immortal sovereign, and a whole bunch of fated villains who had transmigrated into books with a System.

To survive in the cracks between them, Chen Xian decided from the start to trick an amnesiac female cultivation demon lord into becoming his wife.

Cultivation, you say? My wife can cultivate with me!

But even neutral creatures have a golden finger.

[Absolutely Neutral Creature] + [Universal Social Pass]!

As long as he remains neutral, he can ignore attacks from both heroes and villains.

As long as he has a safety helmet and a stepladder, he can go wherever he wants.

And so, Chen Xian accepted his role as an ordinary bystander and began stirring things up between both sides.

The heroes and villains got swept up in the bystander's provocations and beat each other senseless without knowing why. Then they looked around:

What the hell? Where are my magic treasures? Where's my fiancee? How did some random bystander pack up and take everything I own?
