Ordinary people tremble, but I awakened [Underworld Sign-in System]. Sign in at the Mass Grave, unlock the [Soul Suppression Seal], and kill the female ghost in red with one palm! Sign in in the underworld and get the [Judge's Pen], which determines life and death with one stroke! Sign in at Fengdu Ghost City, awaken the [bloodline of Yin Tianzi], and rule all ghosts!

The host subdues the ghost general, and the reward is: the artifact·soul-locking chain!" When all the ghosts worshiped and all living beings were in awe, I discovered—— This weird world is just my back garden!
