Haunted House Sleep Tester: I Am the Underworld's Son of Heaven, and All Ghosts Kneel

Burdened with millions in debt, his mother gravely ill and bedridden, and the hospital repeatedly demanding astronomical medical bills, Wang Yue’s life had already plunged into an abyss.

His company went bankrupt, his friends and family abandoned him, and with nowhere else to turn, he had no choice but to accept a bizarre job that paid an exorbitant fee, one everyone else avoided: spending the night in a century-old haunted house.

Everyone said the place was haunted, that vengeful spirits claimed lives after dark, and that no one who entered had ever made it out safely.

But to save his mother, he had to go, even if it meant taking a road straight to the underworld.

The old house was deathly silent in the dead of night. Bone-chilling cold filled the air, and a sinister wind swept through the halls.

As soon as midnight struck, a piercing wail rang out. A rotting black shadow slowly emerged, and the century-old vengeful spirit opened its icy eyes and lunged at him with lethal force.

With death just a breath away, Wang Yue was overcome with despair and could barely breathe. Then a cold, mechanical voice echoed in his mind.

[Ding! Netherworld System successfully bound!]

[Host detected as the last descendant of the ancient Yin Son of Heaven. Innate Yin Veins automatically activated!]

[Mandatory beginner task: Survive until dawn!]

A clear status screen and a bestiary of ghosts appeared before his eyes. From then on, the dark and supernatural world became a place of data and rules.

A boy on the brink of despair now held dominion over Yin and Yang and the netherworld after just one night. All ghosts would bow before him!
