Fairy Tail, This Plot Is Wrong

Semi-invincible in the early stage, invincible after Tenrou Island in the later stage. Multiple heroines (including Erza and Mira). You Feng accidentally came to the world of Fairy Tail and obtained the inheritance of the Chinese Dragon God. On the way to join Fairy Tail's mission, he met Olgast, and he was also with Mavis. When I returned to the guild, I saw Gildarts pestering Kana again. When I came to the north, I found Uru and Urrutia learning magic. They went to find Erza. Irene bought a yard next door and went to find Mira. Mira hugged him directly. Something doesn't seem right about this Fairy Tail plot. Oh, it seems to be me. That's okay.
