Wang Dalong's Summoning System of the Heavens

Hello, my name is Wang Dalong. I don't know why. When I woke up, I had an additional mental retardation summoning system, and I came to this world full of mythology. Those monsters raging in the sky, those huge dragons, and those monsters and monsters wandering around. What are these things, and more! Who I am? I'm there! Also, this mentally retarded summoning system, what the hell does it summon? It's completely useless! Who said that? I have the system in hand and I own the world. Come out and get beaten! ! !
