《Interim Regulations on the Management of Demons in the Nation of Donghuang》
"Any demon that crosses the boundary and harms humans shall be executed without exception."

In a dark alley, eighteen-year-old student Shen Chang'an stared expressionlessly at the demon before him as he recited the regulations.

As the highest-ranking commander of Qingzhou's Nightwatch Division, handling incidents like this was second nature to him.

***

Eighteen years ago, countless abyssal rifts tore open the sky, and demonic creatures surged forth like an endless tide.

That day became known as the 《Black Swan Incident》.

On that very same day, an abandoned infant was left alone amidst the fleeing crowd.

Eighteen years later, a young man named Shen Chang'an emerged from Qingzhou.

At the age of fifteen, he became the commander of Qingzhou's Nightwatch Division. At eighteen, he fell into the Abyss. Everyone believed he had perished, yet instead he discovered Zhenyuan City, a lost city buried deep within the Abyss. There, he inherited long-lost techniques before returning to Donghuang.

When the great aristocratic clans came to intimidate him, he tore down half of their manor.

When an abyssal rift threatened to devour the land, he stood alone at its mouth, refusing to retreat even a single step.

Yet there was only one thing he truly wanted:

To uncover what had really happened on that night eighteen years ago.

But when he finally reached the edge of the truth, he discovered that the waters of Donghuang's cultivation world ran far deeper than he had ever imagined.

This era needs a hero.

As for who that hero is—

That doesn't matter.
