I Turned Over the Supernatural Realm, and the Nation Helped Me Become a Top Exorcist

[Ghosts cannot be killed.] [Understand the rules governing ghosts to secure a chance of survival.] [Only ghosts can deal with ghosts.] [Gold can contain supernatural activity.]

What would you think if you saw these four statements written on your school's blackboard?

Ye Yan transmigrated after finding an amber bead at a secondhand market, arriving in a world where the supernatural was resurging.

Here, ghosts killed without a trace. Gods and Buddhas were useless, and even technology and modern weapons were ineffective.

Facing a world overrun by supernatural forces, Ye Yan knew he couldn't survive on his own, so he chose to contact the country of his ancestral homeland, the Dragon Country! Only with the nation's support would he have a chance of fighting back against wave after wave of supernatural invasions.

Rules that couldn't be understood? The nation devoted all its resources to analyzing them, even using big data to calculate ways to control the supernatural!

The precious gold of the ghost realm? The nation supplied it in full, helping Ye Yan build the first safe house!

Supernatural entities growing increasingly uncontrollable? The nation provided research and analysis, developing drugs to suppress them...

While the nation supported Ye Yan, Ye Yan also gave back to the nation!

The constantly changing and multiplying ghost skin was controlled through layering, allowing the nation to develop the perfect adaptive camouflage optics, capable of tracking environmental changes!

The parasitic ghost hand that grew back became the subject of research, leading the nation to develop limb-regeneration technology!

The ghost bell that made anyone who heard it lose control of their emotions became the nation's most powerful alarm system when used properly...

As Ye Yan became a top ghost-tamer with the nation's help, the Dragon Country on his ancestral homeworld gradually became the most powerful nation on the planet...

Years later, the supernatural descended into reality.

The other countries were horrified: Why is everyone in the Dragon Country a ghost-tamer?!!!
