I Use Magic in Fantasy

Traveling from the magical world, he discovered that this fantasy world was actually based on elements. With the memory of his previous life and his carrying system, wouldn't it be soaring into the sky? I heard that a genius can only cultivate the power of three elements at the same time. Sorry, I have eight! Are you saying that there are too many cultivation elements, the affinity is too low, and the cultivation is too slow? Sorry, I was an all-powerful magician in my previous life!
