The tragic side story no one cared to fix.Discarded by his clan. Humiliated by his siblings. Dead by suicide before the main plot even began.Guess who woke up in his body?Yeah. Me.Now I’m stuck in a game world that had zero lore, zero guidance, and zero chance of survival — except for the broken-ass Talent I somehow unlocked.I’ll kill, steal, lie, betray—whatever it takes.If survival means blood on my hands, then so be it.I didn’t choose this world, but I’m not going to let it chew me up and spit me out.I’ll climb over corpses if I have to. I’ll become the villain, the monster, the nightmare they never saw coming.Because in this world, there’s only one rule that matters: survive or die.And I’m not dying again.~~~More tags: no Yuri, no NTR, transmigration, rarebloodline, no dense mc, dragons, dragon girl, dog girl, vampire, succubus, mana cultivation, cursed heir, academy setting, secret identity, hidden talent, demons, death and rebirth, political intrigue, ancient bloodline, dark fantasy, family conflict.
