In the Midst of Catastrophe, I Am the Ultimate Calamity

[Corruption + Extreme Cultivation + Revenge + Dark Tone + No Female Lead + No Harem + Calamity and the End of Cultivation + Unhinged and Ruthless + Decisive and Merciless] Before the great calamity arrived, order had already collapsed. A century of pagodas, ruthless cultivators, and commoners treated like dogs. The young man watched with his own eyes as his only family member was beaten to death in the street. In the end, his hair turned white, and he lost all humanity. Resources are taken by force. You make your own connections by fighting. Ruthless, mad, and cunning, he follows the extreme path, founds the Mad Sect, and dances wildly on the edge of a blade. An unparalleled young man becomes an unrivaled great evil! (No System, no good people, cruel and ruthless, stopping at nothing. Truly inhuman. If that bothers you, don't read. Do-gooders, don't read. Do-gooders, don't read.)
