My 'Grandfather' is a Demonic Cultivator

Once hailed a genius, Qin Hao is now a crippled waste, ridiculed by his clan and abandoned by his betrothed. Drowning in despair, he clings to a rusted ring – his last relic of hope. Within it stirs Ji Jiu, an ancient, infamous Demon Patriarch. This sinister 'grandfather' offers Qin Hao forbidden cultivation arts, promising unparalleled power and a path to reclaim everything. Qin Hao’s ascent is meteoric, his enemies fall before his ruthless might. Yet, as his strength soars, a chilling truth unfolds: every victory, every act of vengeance, pushes him closer to becoming the very monster guiding him, threatening to consume his humanity and his soul.
