"Having passed through the Tomb of the corpse, you now face Huangquan Road, the true Threshold of Death, where all powerful Demon Spirits have perished."
"Ha-ha, you must be surprised, why are The Other Side, San Tu, Wangchuan, and Huangquan so powerful?"
"The reason is simple, The Other Side, San Tu, Wangchuan, and Huangquan are the four strongest Demon Spirits selected from all the challenger spirits!"
"To step into the Immortal Sky Realm is no easy feat, and it's not just about defeating the four guardians. All challenger spirits must defeat the four guardians, take their places, and then guard for four long years. Only if no other spirit replaces them during this guarding period do they qualify to wear the Demon Crown and step into the Demon Tomb Inner Island," the Elderly Fox Man explained, pointing at the Demon Crown on the screen.
