Rule-Breaking Tales, but With Money to Burn [Infinite]

Blurb:

Jiyao went to the wrong grave on Tomb-Sweeping Day and burned over ten billion ghost coins, plus a safe, for some unknown wandering ghost.

That night, a supernatural rules game descended, and Jiyao was swept into a horror instance crawling with ghosts.

Faced with paranormal rules with no solution, terrifying bloodthirsty ghosts, and scheming players... Jiyao figured she wouldn't survive three chapters.

But then:

[ Ding! Congratulations, you've inherited the balance in the Underworld Bank account of a lonely wandering ghost: 9999999999 hundred million ghost coins! ]

[ Task refreshed: Money Makes the Ghosts Turn the Millstone. Spend 10,000 ghost coins in three minutes! ]

[ Task reward: One handsome ghost bodyguard, at your side! ]

Jiyao: ?!

-

The world moves forward, and the times make progress. Feudal customs are gradually being abolished, and burning paper money at graves is no longer allowed.

All the ghosts are scraping by, without a single coin to their names.

With no other choice, they enter instances to work.

For every instance they complete, they earn the princely sum of ten yuan!

Then one day

A young woman! She's here! She's brought 9999999999 hundred million in cash! She's scattering (ghost) money like crazy!

From then on, all the ghosts understood that money really can make ghosts turn the millstone!

And Pei Yan, the terrifying Big Boss who strikes fear into every player, the mighty Ghost King and captain of the security team, led by example. At Jiyao's hint of a glance, he bashfully (?) undid his buttons (?) and followed her back to her room...

Players: ?!!?

Wait... Rich lady, they can do that too!

Ghosts: →_→ Get in line!

Couple: A beautiful but sickly girl, rich beyond belief * a handsome, incredibly powerful Ghost King who's dirt poor
