My Nightmare Carriage Connects Worlds

Sigmund was trapped. Twenty-seven agonizing days, reliving the same brutal blizzard, the same hunger, the same gruesome deaths. He died seven times, burying himself, only to wake up and repeat the nightmare. Despair was his only constant. Until the 28th day. A phantom carriage, wreathed in dark flames, burst through the loop. It wasn't just an escape; it was his Golden Finger, a monstrous system that offered grotesque gifts: flesh-boosting fruits and enlightening forbidden books. Now, strong enough to shatter bones, he's a servant in a decrepit manor, playing house with a doll-obsessed boy and his 'sister'—a disturbingly lifelike mannequin. But the manor hides more than just eccentricity. Its staff aren't merely human, and the carriage's next destination promises realms far stranger than this nightmare… or perhaps, far more familiar.
