Raiding the Immortal Realm

This is a cultivation novel themed around the "world." A jailer from the Demon Realm’s Infernal Prison was sent to the mortal world to carry out a mission assigned by the Demon Realm: cultivate as an immortal undercover agent. Using the astonishing secrets and immortal arts he learned while torturing captured immortals as a prison guard, he turned his sinister demonic claws toward those reincarnated in the mortal world... "The Demon Realm knows that our Immortal Realm has celestial immortals and Great Luo Golden Immortals with inner worlds, and that they are reborn in the mortal world after death. But they don’t know that the inner worlds they cultivate are beyond the reach of reincarnation. Even if they become mortals with no memories, their worlds remain within them!" An inner world is a Sumeru realm that only experts at the celestial immortal level can open within themselves. Let me reiterate: Treading the Immortal Path, Ascending to Demonhood is being held back by the publisher, but it will absolutely be completed, or I’ll be fined. As for Stirring Up Trouble Away from the Immortal Path, the editor rejected it, so YD didn’t deliberately abandon it.
