I'm a City Ghost Officer. Is It a Problem to Get the System for Free?

I'm an urban ghost officer, and I've awakened the World's Most Shameless System!

The System's name makes it clear I'm supposed to be shameless, so there's nothing wrong with using the powers of the underworld to get the System for free, right?

As the saying goes, the more shameless you are, the stronger you get! That's me, Wang Xiaoyi!

In this world, where the upgrade paths for Systems are monopolized by a few powerful groups, other people need upgrade crystals worth millions...

But me? Zero cost! Mass production!

Other people's divine weapons require cash shop spending? My cultivation techniques are cheap and shameless: "Look! You're getting worked up again!"
