The World Tree I Cultivated

I am a tree keeper, but the tree I raise is the world tree. The big guys from all the worlds respect me very much, but I am just a mortal, except I can destroy a world with one hand. I traveled around the world, leaving my own legends among humans and gods. Looking at their trembling legs, I just want to say, I am really just a mortal! ! ! !
