Ghost Apocalypse? I Am the Lord of the Underworld!

A burned-out office worker transmigrates to another world and becomes a powerful figure. Using the Underworld as a foundation, he gathers strength through contracts to counterattack in desperate situations, leading his partners to the peak and writing a legendary tale. After dying suddenly and crossing into a post-apocalyptic blue star, Chen Mu's ordinary mansion hides a shocking secret—it is the Underworld ruling over ten thousand ghosts! Betrayed by a green-tea type, he forms contracts with a fallen school beauty and a loyal brother, transforming mortal weapons into heavenly-tier artifacts. As evil ghosts ambush the trial ground and the blue fire legion emerges, a mysterious phenomenon reveals a more sinister crisis and unknown fate behind the scenes, with the path to counterattack hiding deep mysteries.
