Mage Adam - Chapter "369"

After dying a pathetic death as an overworked office drone, I woke up reincarnated as Archer—the bastard prince of the Brutish Empire.My existence is a royal secret as My father, the King, would rather pretend I don't exist. My half siblings get royal treatment while I'm hidden away like a dirty secret.But I have a secret of my own. I was OP.By age two, I realized monsters flee from my stupidly OP mana. By age ten my mana could level cities—if I dare to unleash it.When my half-sister is kidnapped by the demon king, I finally decided to step out of hiding to become the strongest in this new world.

Yiwen traveled through time, but Yiwen didn’t panic at all…

Because he traveled with him, as well as the character template in the mobile game, and the five devil fruits obtained by the lottery.

Yiwen believes that she can rely on the special physique obtained by charging six yuan for the first time, and the devil fruit in the backpack, and become a strong party in the world of One Piece.

Until Yiwen opened her eyes and saw a crimson dragon.

Only then did Yiwen realize that this was not One Piece at all, but Fairy Tail!

Start to capture Erza? The start was captured by Irene!
