I Am a Demon Cultivator in the Real World

The magic book is opened... "Closing the world passage, besieging and killing low-level races, carrying out genocide, and gaining 2 points of the origin of the devil." "Encountered three demon saints to snatch spiritual treasures, injured the demon saints, and gained 4 points of the origin of the devil." "Encountered an ancient ferocious beast, suppressed it with one palm, and gained 6 points of the origin of the devil." "Set up the origin formation, destroy the immortal king of the foreign land, and gain 8 points of the origin of the devil." … After a serious illness, Chen Yuan had a magic book in his mind. He looked at the words that emerged from the magic book and didn't know how to complain. "Closing the door to kill mosquitoes is called genocide?" "I encountered three monkeys snatching bananas at a tourist attraction. Is this called the Monkey King?" "This big duck is called an ancient beast?" "Use a toy trap to trap a seven-year-old naughty child and call him to destroy the immortal king of a foreign land?" … "Wait a minute, what does it mean that I have become a great evil emperor who is the source of darkness and turmoil in the world?" This book is also called "Guide to Demonic Cultivation", "No One Knows Demonic Cultivation Better than Me", "I've already practiced Demonic Cultivation, and I don't care what you do", "There's Something Wrong About This Demonic Cultivation", and "Meet the Master Demonic Cultivator".
