Fairy Tail : Sign-In To Become Invicible

Transmigrated to the fairy tail world and got the sign-in system. Dragon Slayer Magic, Celestial Spirit Magic, Ancient Magic, and all other types of magic have all been learned. Since then, Dino has became the strongest in the Fairy Tail world. Makarov: “Ah! I’m really old, and it’s time to hand over the guild to Dino. He is much stronger than me.” Zeref: “It turns out that in addition to my brother Natsu, Dino is strong enough to kill me!” Acnologia: “Too strong, how could Dino be countless times stronger than me!” Mirajane : “Ara - Ara, Dino is indeed my man, and he is indeed the most powerful.” (Hey Guys, I'm translating this fanfic for fun, using ai, my english is not good)
