I've Spent Sixty Years Exorcising Demons, and You Call Me Cruel? Fine, All of You Can Come at Me

[Invincible from the Start] + [Satisfying Power Fantasy] + [No Female Lead] + [Decisive and Ruthless] + [Destroys a Sect in Ten Chapters] + [Brings About the World's End in Fifty Chapters] + [Proves the Dao Through Slaughter] My name is Chen Mo. I am a transmigrator. In this world, overrun with demons and monsters and crawling with evil spirits, I awakened the Demon-Slaying System. As long as I slay demons and monsters, I can gain Justice Points and grow infinitely stronger. To stay alive, and to protect those behind me, I gripped the blade in my hand. I guarded Demon-Suppressing Cliff for an entire sixty-year cycle. For sixty years, I slew demons until they trembled in fear, wiped out the evil spirits, brought peace to the four seas, and secured tranquility in every direction. Everyone respectfully called me the True Lord Who Suppresses Demons. As a result, my sect, the Tianyuan Sect, became the greatest righteous sect under heaven, enjoying the incense offerings of countless generations. I thought my life would go on like that. Until, on the day of my hundredth birthday, the sect held a grand celebration in my honor. The founding ancestor, who had long lived in seclusion, arrived before the eyes of the assembled crowd. Pointing at me, he declared that my countless killings had left me steeped in murderous energy and that I had become possessed by demonic influences. He said I had incurred Heaven's wrath and would bring utter destruction upon the sect. He even planned to cripple my cultivation, seal me beneath Demon-Suppressing Cliff, and keep me from ever being reborn. I looked at the fellow disciples and cultivators around me, those I had once protected, now staring at me with fear and greed in their eyes. I smiled. Sixty years of protecting them had earned me nothing but betrayal and false accusations. So-called righteous sects turned out to be filthier than demons and evil spirits. "You call me brutal?" "Fine." "In that case, you can all join me on the road to the afterlife."
