Fantasy: I Am the Mythical Beast at the Beginning!

I, a young man from Blue Star, traveled through time and became a big tortoise? Holy shit! The key is that I don't have any memory of this big turtle. Who am I? Where am I? What are you doing? I don't know at all, I just know that this place looks like ancient times on Blue Star, judging from the costumes of these people. Fortunately, I can understand what these ancients said. They seem to be praising my deeds, judging from the information revealed in their praise. This big turtle, which is me, is named Jiankang, and it is a mythical beast. Jiankang has endless life, unrivaled strength, and a huge body. In short, high physical attack, high blood volume, large size, and slow speed. This novel and its characters are purely fictitious.
