Starting from the Tomb of Remnant Souls: I Rebuild the Demon Realm

In this world, where immortals and Buddhas control the heavens and human races live, the demon race can only huddle in the cracks of the corpse mountain and the sea of ​​blood - the so-called "ten thousand demons" are just the medicine in the immortal sect's alchemy furnace and the sacrifices on the human altar. He is a remnant of the candle dragon who is about to starve to death. His scales have been peeled off and his dragon tendons are about to be broken. He lives in the sewer of the "Soul Refining Workshop" where demon clans are slaughtered. Until one day, the abandoned dragon bone that was eaten suddenly cracked, revealing the bronze key of the ancient "demon prison". The moment the key was stained with blood, the "Sutra of Ten Thousand Demons' Calamity" that had been sleeping for eternity exploded in his soul sea: "If an immortal presses you, the day will be shattered; if a human bullies you, the ground will be flattened!" When the first ray of netherworld candlelight rose from his remains, the three realms were shocked to realize that the ancestor of all demons who was suppressed by the immortals and Buddhas was using this dying body to burn away the shackles of heaven! But those immortal monks who cut off his scales and whipped his dragon tendons would not have thought that what they were feeding with their own hands was their own gravedigger.
