Shadow Dragon: The Fallen Angel Is My Teacher

[Awakening Supreme God’s Treasure: Shadow] [System Boot Successful] [Host can now gain infinite classes.] [Hint: Complete hidden requirements to gain a Class.] [Alert! Host is too young. Dispatching a Fallen Angel to guide the host. The Guide is allowed to share Class requirements with the host.] The world hides its teeth. Mages, warriors, vampires, and gods aren’t stories. They exist, hidden from ordinary eyes. The world dances on their whims. I was one of the clueless. I lived my life believing the world was normal… until I found out the truth. By then, it was too late for me. All I could do was survive in the darkness, working as an assassin for the one I once called my master. But in the end, I was betrayed. I was killed once my use was over. I thought it was the end. But fate had other plans. I woke up as a newborn — on Earth — with all my memories intact. “I’ve returned to the past?” And it was not a simple return. I had gained the strongest weapon in existence. [Shadow], the treasure of the Supreme God. I was thrilled… but the surprises didn’t stop there. I found I had the blood of dragons! Now, armed with one of the strongest bloodline, the most powerful assassin Class, and a Fallen Angel as my mentor, I would take my destiny into my own hands. This time, I’ll grow stronger from the cradle. I’ll kill every traitor who betrayed me. I’ll take everything I was denied. No more masters. No more chains. This time— I’ll live for myself.
