Alien Beast: Become a God from a Lizard

I am the god of the mountains and a great and noble ancient dragon. My body is as huge as a mountain, and the mountains shift at every turn, and the earth trembles. My followers are all over the alien world, and the giants and dragons are my followers. The people who believe in me call me the Lord of the Mountains, Terratar Horn. And I was just an ordinary boy named Chen Zhou in Blue Star. Just one day ago, I was a defeated dog, connected to countless worlds, where magic, cultivation, and superpowers all became real, and I lived a life that was inferior to that of ordinary people. But everything changed, I became the host of the system, but why does this cheating system not act according to common sense?
