I Became a Demon Emperor, and the Immortal Realm Issued an Order to Slay Me

After transmigrating to the world of immortal cultivation, Gu Changge discovers that being a demonic cultivator is incredibly difficult. Cultivation techniques, divine abilities and forbidden arts, magical treasures, and parasitic insects all require piles of ordinary people. But killing is intolerable to the Heavenly Dao of the human race. The demonic sects have also been wiped out by the righteous path, leaving their members branded enemies of all and treated like rats in the street. Luckily, the Horror Game reaches across servers to recruit him, and Gu Changge becomes an NPC, able to travel freely between the world of immortal cultivation and the Horror Game world. From then on, cultivation materials are inexhaustible. The Heavenly Demon Codex requires countless vengeful souls? As far as I know, tens of thousands of evil ghosts die by accident in the Ghost Realm every day. I can just collect the bodies. What can those city-slaughterers possibly do to compete with me? The Ten Thousand Souls Banner needs evil ghosts? I’ll hold a recruitment fair and hire them at sky-high rates to enter the banner. A hundred years from now, we’ll ascend with the banner, and every one of them will become a Ghost Immortal. That day, hundreds of millions of evil ghosts came to apply. Many years later. Gu Changge, who had long since played it safe and become a Demon Emperor, faces the Immortal Realm’s decree to exterminate demons. Transforming into the Primordial Heavenly Demon, he launches a counterattack against the Immortal Realm. Only then does he realize that the immortals and gods in heaven are nothing special!
