Shadow Dragon: The Fallen Angel Is My Teacher

The story

The deadliest assassin inherits the blood of dragons. ... The Exorcist Clans failed and Earth fell. A few escaped to another world — including him — but the one he served betrayed and killed him. He should have died. Instead, he wakes on the day he was born. “I've returned to the past.” Earth is still standing and the Exorcist Clans have no idea of what's coming in the future. Now, armed with the dragon blood, the strongest assassin Class, and a Fallen Angel granted by the System as his mentor, he just doesn’t want to save the world. No, that goal is far too small. He wants vengeance. He will hunt down everyone who destroyed his world and every hand that killed him. *** Additional Tag: #Bloodline Evolution, #Heir of a Rich Family, #Genius, #Swordmaster, #Reborn in a Magical Family, #Space Magic User, #Master of All, #Hidden Bloodlines, #Multiple Worlds, #Gods, #Demons, #Elves, #Vampires, #Mythical Species, #SCP Universe
