Demon Slayer: My Talents Stack Infinitely

Ten minutes before Muzan massacres the Kamado family, Xue Kang finds himself thrust into the world of Demon Slayer with one impossible mission: save them all. The system's rewards are too tempting to ignore, but can he really rewrite fate when he's just arrived? Armed with a unique talent that stacks infinitely with each victory, he's willing to gamble everything. In a world where demons lurk in shadows and breathing techniques mean the difference between life and death, one transmigrator will discover that unlimited growth might be exactly what humanity needs to turn the tide.
