At the dead of night, he patrols with his watchman's lantern, illuminating the shadows.

Through haunted alleys echoing with ghostly wails, he walks alone.

A single life-lantern lights the endless night;
Half the street lies in wind and rain, half in clear skies.
To safeguard lasting peace for one land,
To keep the lights of ten thousand homes forever burning.

Such is the duty of the Midnight Watchman.

Li Muxuan transmigrates to a world overrun by malevolent spirits.

By day, the blazing sun hangs high in the sky, its scorching rays keeping the spirits at bay.

But when night falls, the malevolent spirits emerge in droves, driven by a single purpose—

To devour humans.

Among the common people exists a unique profession. Using their own souls as the wick and their flesh and blood as the wax, they kindle spiritual flames to illuminate the darkness, drive back the night, and exterminate the malevolent spirits.

They are known as—

The Midnight Watchmen.

Li Muxuan awakens the Illustrated Compendium System. By collecting and recording malevolent spirits, he can summon them to fight on his behalf.

But before he can begin pursuing his grand ambitions, he becomes the victim of his parents' favoritism. Forced to marry Luo Bingyun—the fiancée his younger brother had rejected—he has little choice but to accept his fate.

What no one expected, however, was that this seemingly fallen eldest daughter of the Luo Clan...

...is actually the Empress, reborn.
